+= Spaces around h1 tags
+:updatedat: 2021-08-15
+
+_EDIT_: Apparently, the behaviour below is consistent between Firefox and
+Chromium for links, but not for `<h1>`.  My conclusion is that the `<h1>`
+behaviour is a Firefox quirk, but the `<a>` is expected.

+'''''
+
+The HTML below has selectable extra spaces after `<h1>` tags:

+# Rollout, feature flag, experiment, operational toggle
+Different use cases for **backend**, **frontend** and **mobile**
+
+---
+
+"Feature flags" tend to come up when talking about **continuous deployment**
+
+???
+
+I'm using "quotes" because I'm mixing up different meanings of "rollout"
+
+---
+
+# CI
+continuous integration
+
+# CD
+continuous delivery
+
+# CD
+**continuous deployment**
+
+???
+
+Background: build vocabulary, why are feature flags related to CD
+
+CI solves: manual integration of long-lived branches
+
+CD solves: automation of deployment process
+
+CD solves: releases as frequent as possible
+
+That's where the "GoCD" name comes from

+
+---
+
+We now know about the types
+
+## But they have different relevance for **backend**, **frontend** and **mobile**
+
+---
+
+# backend
+
+1. **rollout**: k8s blue/green, canary and ~`common-rollout`~ `common-xp`
+2. **feature flag**: ~`common-rollout`~ `common-xp` and datasets
+3. **experiment**: `common-xp`
+4. **operational toggle**: ~`common-rollout`~ `common-xp`
+
+???
+
+This is a bit why common-rollout isn't called *common-feature-flag*: it was
+initially designed with backend usage of mostly *rollouts* in mind, and just a
+bit *feature flags*.
+
+Avoid using configuration for doing operational toggles: it is less dynamic, so
+it defeats the purpose.
+
+---
+
+# frontend
+
+1. **rollout**: CDN and page refreshes
+2. **feature flag**: percentages and maybe IPs (no `:customer/id` on the website)
+3. **experiment**: via dynamic backend control
+4. **operational toggle**: via dynamic backend control
+
+---
+
+# mobile
+
+1. **rollout**: app stores
+2. **feature flag**: via dynamic backend control
+3. **experiment**: via dynamic backend control
+4. **operational toggle**: via dynamic backend control
+
+---
+
+Key differentiator is
+## How much **control** we have over the **environment**
+
+---
+
+## **backend**
+
+# Full control
+🎉
+
+???
+
+Can edit, update and even delete rollouts as desired.
+
+Mix and match at will!
+
+---
+
+## **frontend**
+
+# Partial control
+
+When choose when to make a new version available
+
+???
+
+We can control when a new version is available, partially when someone will
+upgrade it.
+
+But it is easy to fallback to "reload the page and try again".
+
+---
+
+## **mobile**
+
+# Very limited control
+
+- app stores can restrict updates (worse for iOS)
+- customers still have to download new versions
+
+---
+
+# Costs
+
+- more complex code
+- compatibility with old app versions
+- nesting is exponential
+
+---
+
+# Benefits
+
+- dynamicity
+
+---
+
+## Weighting costs × benefits
+
+The less control we have, the more we value dynamicity
+
+---
+
+## Weighting costs × benefits
+
+- backend: sometimes worth the cost
+- frontend: almost always worth cost
+- mobile: **always** worth cost
+
+---
+
+# Best practices
+
+---
+
+## Dynamic content > feature flag
+
+Always true for **mobile**, almost always for **frontend**
+
+---
+
+## Use `:include-list` for named groups
+
+Always true for **backend**, **frontend** and **mobile**
+
+{% raw %}
+```clojure [2-3]
+{:rules
+ #{{:type    :include-list
+    :content {:filename "debit-team-members.txt"}}}}
+```
+{% endraw %}
+
+---
+
+## Always use `:app-version`
+
+only for **mobile**
+
+{% raw %}
+```clojure [2]
+{:rules
+ #{{:type    :app-version
+    :content {:min-version #{{:platform :android
+                              :code     1000000}
+                             {:platform :ios
+                              :code     2000000}}}}}}
+```
+{% endraw %}
+
+---
+
+## Extend ~`common-rollout`~ `common-xp` if required
+
+That's how `:include-list`, `:app-version`, *etc.* were born
+
+---
+
+## Beware of many nested feature flags
+
+True for **backend**, **frontend** and **mobile**
+
+???
+
+Exponential growth of combinations
+
+---
+
+## Don't delete app-facing feature flags
+
+True for **mobile**
+
+???
+
+This could break old app versions, only do this intentionally
+
+We don't have (yet) a strategy for dealing with LTS of the app, and we just say:
+"we'll support every app version out there".
+
+---
+
+## Include a feature flag on the whiteboarding phase
+
+---
+
+## Include deleting/retiring the feature flag at the end
+
+---
+
+## Avoid renaming a feature flag
+
+Use `:app-version` with `:min-version` instead
+
+---
+
+# And most importantly...
+
+---
+
+# ***Always*** rely on a feature flag on the app
+
+Never do a hot fix, avoid expedited releases at all costs
+
+???
+
+The app is where we have less control, so the feature flag is how we get some of
+that control back.
+
+This doesn't mean you'll need 1 feature flag per PR
+
+There's not such thing as:
+"This is such a small thing, it doesn't need a feature flag"
+
+You should ask yourself:
+"It this crashes the app, am I OK with waiting for the next release train?"

+## Towards a Better Future
+
+CRDTs (Conflict-free Replicated Data Types) as a Foundational Technology
+
+---
+
+### Use case
+
+```
+# in node A and node B
+s = "Hello, World"
+
+# in node A
+s = "Hello, Alice"
+
+# in node B
+s = "Hello, Bob"

+# Part 2

+Critique
+
+---
+
+### Software license
+
+> In our opinion, maintaining control and ownership of data does not mean that
+> the software must necessarily be open source.
+
+---
+
+#### Example 1 - intentional restriction
+
+```bash
+#!/bin/sh
+
+TODAY=$(date +%s)
+LICENSE_EXPIRATION=$(date -d 2020-10-27 +%s)
+
+if [ $TODAY -ge $LICENSE_EXPIRATION ]; then
+  echo 'License expired!'
+  exit 1
+fi
+
+echo $((2 + 2))
+```
+
+```bash
+# today
+$ ./useful-adder.sh
+4
+# tomorrow
+$ ./useful-adder.sh
+License expired!
+```
+
+---
+
+#### Example 2 - unintentional restriction
+
+```bash
+# today
+$ useful-program
+# ...useful output...
+
+# tomorrow, with more data
+$ useful-program
+ERROR: Panic! Stack overflow!
+```
+---
+
+### local-first **requires** free software
+
+Otherwise "The Long Now" (ideal nº5) is lost
+
+---
+
+### Denial of existing solutions
+
+> In principle it is possible to collaborate without a repository service,
+> e.g. by sending patch files by email, but the majority of Git users rely
+> on GitHub.
+
+Solution: either  GitHub+CRDTs or `git` **`send-email`**
+
+---
+
+### Plain text formats
+
+> Git is highly optimized for code and similar line-based text file
+
+It even pulls software to the plain text direction, e.g.:
+- delivery-templates
+- `common-core.protocols.config`
+
+Why not exploit that more?
+
+---
+
+### Ditching of web applications
+
+> The architecture of web apps remains fundamentally server-centric
+
+Disagree.  Contrast [PouchDB][pouchdb] with Android [Instant Apps][instant-apps]
+
+[pouchdb]: https://pouchdb.com/
+[instant-apps]: https://developer.android.com/topic/google-play-instant
+
+???
+
+Talk on dynamic content
+
+---
+
+### Costs are underrated
+
+- storage
+- backups
+- maintenance
+
+Example: blog vs vlog
+
+---
+
+### Real-time collaboration a bit overrated
+
+It is only possible on the presence of reliable, medium-quality network
+connection
+
+> X also works when inside an elevator, subway or plane!
+
+<!-- 🤦‍ -->
+
+---
+
+### On CRDTs and developer experience
+
+> For an app developer, how does the use of a CRDT-based data layer compare to
+> existing storage layers like a SQL database, a filesystem, or CoreData?  Is a
+> distributed system harder to write software for?
+
+Yes.

+
+---
+
+## Conclusion
+
+Why this is a "paper I love": it took offline-first and ran with it.
+
+But a pinch of CRDT won't make the world local-first.
+
+The tricky part is the end of the sentence: "**in spite of the Cloud**".

+= Simple filename timestamp
+:categories: shell
+
+When writing Jekyll posts or creating log files with dates on them, I usually
+struggle with finding a direct way of accomplishing that.  There's a simple
+solution: `date -I`.
+
+[source,sh]
+----
+./my-program.sh > my-program.$(date -I).log
+cp post-template.md _posts/$(date -I)-post-slug.md
+----
+
+Using this built-in GNU/Linux tool allows you to `touch $(date -I).md` to
+readily create a `2020-08-12.md` file.
+
+I always had to read `man date` or search the web over and over, and after doing
+this repeatedly it became clear that both `date -I` and `date -Is` (`s` here
+stands for seconds) are the thing that I'm looking for 95% of the time:
+
+[source,sh]
+----
+# inside my-program.sh
+echo "Program started at $(date -Is)"
+# output is:
+# Program started at 2020-08-12T09:04:58-03:00
+----
+
+Both date formats are hierarchical, having the bigger time intervals to the
+left.  This means that you can easily sort them (and even tab-complete them)
+with no extra effort or tool required.

+= Anchor headers and code lines in Jekyll

+:empty:

+:kramdown: https://kramdown.gettalong.org/
+:rouge: https://rouge.jneen.net/
+:jekyll-hook: https://jekyllrb.com/docs/plugins/hooks/
+
+The default Jekyll toolbox ({jekyll}[Jekyll], {kramdown}[kramdown] and
+{rouge}[rouge]) doesn't provide with a configuration option to add anchors to
+headers and code blocks.
+
+The best way I found of doing this is by creating a simple Jekyll plugin, more
+specifically, a {jekyll-hook}[Jekyll hook].  These allow you to jump in to the
+Jekyll build and add a processing stage before of after Jekyll performs
+something.
+
+All you have to do is add the code to `_plugins/my-jekyll-plugin-code.rb`, and
+Jekyll knows to pick it up and call your code on the appropriate time.
+
+== Anchor on headers
+
+:jemoji: https://github.com/jekyll/jemoji
+:jekyll-mentions: https://github.com/jekyll/jekyll-mentions
+:html-regex: https://stackoverflow.com/questions/1732348/regex-match-open-tags-except-xhtml-self-contained-tags/1732454#1732454
+
+Since I wanted to add anchors to headers in all documents, this Jekyll hook
+works on `:documents` after they have been transformed into HTML, the
+`:post_render` phase:
+
+[source,ruby]
+----
+Jekyll::Hooks.register :documents, :post_render do |doc|
+  if doc.output_ext == ".html"
+    doc.output =
+      doc.output.gsub(
+        /<h([1-6])(.*?)id="([\w-]+)"(.*?)>(.*?)<\/h[1-6]>/,
+        '<a href="#\3"><h\1\2id="\3"\4>\5</h\1></a>'
+      )
+  end
+end
+----
+
+I've derived my implementations from two
+"official"{empty}footnote:official[
+  I don't know how official they are, I just assumed it because they live in the
+  same organization inside GitHub that Jekyll does.
+] hooks, {jemoji}[jemoji] and {jekyll-mentions}[jekyll-mentions].
+
+All I did was to wrap the header tag inside an `<a>`, and set the `href` of that
+`<a>` to the existing id of the header.  Before the hook the HTML looks like:
+
+[source,html]
+----
+...some unmodified text...
+<h2 id="my-header">
+  My header
+</h2>
+...more unmodified text...
+----
+
+And after the hook should turn that into:
+
+[source,html]
+----
+...some unmodified text...
+<a href="#my-header">
+  <h2 id="my-header">
+    My header
+  </h2>
+</a>
+...more unmodified text...
+----
+
+The used regexp tries to match only h1-h6 tags, and keep the rest of the HTML
+attributes untouched, since this isn't a general HTML parser, but the generated
+HTML is somewhat under your control.  Use at your own risk because
+{html-regex}[you shouldn't parse HTML with regexps].  Also I used this strategy
+in my environment, where no other plugins are installed.  I haven't considered
+how this approach may conflict with other Jekyll plugins.
+
+In the new anchor tag you can add your custom CSS class to style it as you wish.
+
+== Anchor on code blocks
+
+Adding anchors to code blocks needs a little bit of extra work, because line
+numbers themselves don't have preexisting ids, so we need to generate them
+without duplications between multiple code blocks in the same page.
+
+Similarly, this Jekyll hook also works on `:documents` in the `:post_render`
+phase:
+
+[source,ruby]
+----
+PREFIX = '<pre class="lineno">'
+POSTFIX = '</pre>'
+Jekyll::Hooks.register :documents, :post_render do |doc|
+  if doc.output_ext == ".html"
+    code_block_counter = 1
+    doc.output = doc.output.gsub(/<pre class="lineno">[\n0-9]+<\/pre>/) do |match|
+      line_numbers = match
+                      .gsub(/<pre class="lineno">([\n0-9]+)<\/pre>/, '\1')
+                      .split("\n")
+
+      anchored_line_numbers_array = line_numbers.map do |n|
+        id = "B#{code_block_counter}-L#{n}"
+        "<a id=\"#{id}\" href=\"##{id}\">#{n}</a>"
+      end
+      code_block_counter += 1
+
+      PREFIX + anchored_line_numbers_array.join("\n") + POSTFIX
+    end
+  end
+end
+----
+
+This solution assumes the default Jekyll toolbox with code line numbers turned
+on in `_config.yml`:
+
+[source,yaml]
+----
+kramdown:
+  syntax_highlighter_opts:
+    span:
+      line_numbers: false
+    block:
+      line_numbers: true
+----
+
+The anchors go from B1-L1 to BN-LN, using the `code_block_counter` to track
+which code block we're in and don't duplicate anchor ids.  Before the hook the
+HTML looks like:
+
+[source,html]
+----
+...some unmodified text...
+<pre class="lineno">1
+2
+3
+4
+5
+</pre>
+...more unmodified text...
+----
+
+And after the hook should turn that into:
+
+[source,html]
+----
+...some unmodified text...
+<pre class="lineno"><a id="B1-L1" href="#B1-L1">1</a>
+<a id="B1-L2" href="#B1-L2">2</a>
+<a id="B1-L3" href="#B1-L3">3</a>
+<a id="B1-L4" href="#B1-L4">4</a>
+<a id="B1-L5" href="#B1-L5">5</a></pre>
+...more unmodified text...
+----
+
+Happy writing :)

+= Browse a git repository at a specific commit
+:categories: git
+
+I commonly use tools like `git log` together with `git show` when inspecting
+past changes in a repository:
+
+[source,sh]
+----
+git log
+# search for a the commit I'm looking for
+git show <my-commit>
+# see the diff for the commit
+----
+
+But I also wanted to not only be able to look at the diff of a specific commit,
+but to browse the whole repository at that specific commit.
+
+I used to accomplish it the "brute force" way: clone the whole repository in
+another folder and checkout the commit there:
+
+[source,sh]
+----
+git clone <original-repo> /tmp/tmp-repo-clone
+cd /tmp-repo-clone
+git checkout <my-commit>
+----
+
+But git itself allows we to specific the directory of the checkout by using the
+`--work-tree` global git flag.  This is what `man git` says about it:
+
+[source,text]
+----
+--work-tree=<path>
+    Set the path to the working tree. It can be an absolute path or a path relative to the current working
+    directory. This can also be controlled by setting the GIT_WORK_TREE environment variable and the
+    core.worktree configuration variable (see core.worktree in git-config(1) for a more detailed
+    discussion).
+----
+
+So it allows us to set the desired path of the working tree.  So if we want to
+copy the contents of the current working tree into `copy/`:
+
+[source,sh]
+----
+mkdir copy
+git --work-tree=copy/ checkout .
+----
+
+After that `copy/` will contain a replica of the code in HEAD.  But to checkout
+a specific, we need some extra parameters:
+
+[source,sh]
+----
+git --work-tree=<dir> checkout <my-commit> -- .
+----
+
+There's an extra `-- .` at the end, which initially looks like we're sending
+Morse signals to git, but we're actually saying to `git-checkout` which sub
+directory of `<my-commit>` we want to look at.  Which means we can do something
+like:
+
+[source,sh]
+----
+git --work-tree=<dir> checkout <my-commit> -- src/
+----
+
+And with that `<dir>` will only contain what was inside `src/` at `<commit>`.
+
+After any of those checkouts, you have to `git reset .` to reset your current
+staging area back to what it was before the checkout.

+= Search in git

+
+Here's a useful trio to know about to help you search things in git:
+
+. `git show <commit>`
+. `git log --grep='<regexp>'`
+. `git grep '<regexp>' [commit]`
+
+== 1. `git show <commit>`
+
+Show a specific commit and it's diff:
+
+[source,sh]
+----
+git show
+# shows the latest commit
+git show <commit>
+# shows an specific <commit>
+git show v1.2
+# shows commit tagged with v1.2
+----
+
+== 2. `git log --grep='<regexp>'`
+
+Search through the commit messages:
+
+[source,sh]
+----
+git log --grep='refactor'
+----
+
+== 3. `git grep '<regexp>' [commit]`
+
+:browse-article: link:../14/browse-git.html
+
+Search content in git history:
+
+[source,sh]
+----
+git grep 'TODO'
+# search the repository for the "TODO" string
+git grep 'TODO' $(git rev-list --all)
+# search the whole history for "TODO" string
+----
+
+And if you find an occurrence of the regexp in a specific commit and you want to
+browse the repository in that point in time, you can {browse-article}[use git
+checkout for that].

+= Grep online repositories
+:categories: git
+
+:cgit: https://git.zx2c4.com/cgit/
+
+I often find interesting source code repositories online that I want to grep for
+some pattern but I can't, because either:
+
+* the repository is on {cgit}[cgit] or a similar code repository that doesn't
+  allow search in files, or;
+* the search function is really bad, and doesn't allow me to use regular
+  expressions for searching patterns in the code.
+
+Here's a simple script that allows you to overcome that problem easily:
+
+[source,sh]
+----
+#!/usr/bin/env bash
+set -eu
+
+end="\033[0m"
+red="\033[0;31m"
+red() { echo -e "${red}${1}${end}"; }
+
+usage() {
+  red "Missing argument $1.\n"
+  cat <<EOF
+Usage:
+    $0 <REGEX_PATTERN> <REPOSITORY_URL>
+
+      Arguments:
+        REGEX_PATTERN     Regular expression that "git grep" can search
+        REPOSITORY_URL    URL address that "git clone" can download the repository from
+
+Examples:
+    Searching "make get-git" in cgit repository:
+        git search 'make get-git' https://git.zx2c4.com/cgit/
+        git search 'make get-git' https://git.zx2c4.com/cgit/ -- \$(git rev-list --all)

+  exit 2
+}

+[[ -z "${REPOSITORY_URL}" ]] && usage 'REPOSITORY_URL'
+
+mkdir -p /tmp/git-search
+DIRNAME="$(echo "${REPOSITORY_URL%/}" | rev | cut -d/ -f1 | rev)"
+if [[ ! -d "/tmp/git-search/${DIRNAME}" ]]; then
+  git clone "${REPOSITORY_URL}" "/tmp/git-search/${DIRNAME}"
+fi
+pushd "/tmp/git-search/${DIRNAME}"
+
+shift 3 || shift 2 # when "--" is missing
+git grep "${REGEX_PATTERN}" "${@}"
+----
+
+It is a wrapper around `git grep` that downloads the repository when missing.
+Save in a file called `git-search`, make the file executable and add it to your
+path.
+
+Overview:
+
+* _lines 1~2_:
++
+Bash shebang and the `set -eu` options to exit on error or undefined
+variables.
+
+* _lines 4~30_:
++
+Usage text to be printed when providing less arguments than expected.
+
+* _line 33_:
++
+Extract the repository name from the URL, removing trailing slashes.
+
+* _lines 34~37_:
++
+Download the repository when missing and go to the folder.
+
+* _line 39_:
++
+Make the variable `$@` contain the rest of the unused arguments.
+
+* _line 40_:
++
+Perform `git grep`, forwarding the remaining arguments from `$@`.
+
+Example output:
+
+[source,sh]

+create on a Git hosting provider’s web
+UI{empty}footnote:pr-webui[
+  And maybe even using the Git hosting provider’s API from the command line!
+] like GitLab/Bitbucket/GitHub actually comes from Git itself:
+`git request-pull`.
+
+At the very core, they accomplish the same thing: both the original and the web
+UI ones are ways for you to request the project maintainers to pull in your
+changes from your fork.  It’s like saying: "hi there, I did some changes on my
+clone of the repository, what do you think about bringing those in?".
+
+The only difference is that you’re working with only Git itself, so you’re not
+tied to any Git hosting provider: you can send pull requests across them
+transparently!  You could even use your own {cgit}[cgit] installation.  No need
+to be locked in by any of them, putting the "D" back in "DVCS": it’s a
+*distributed* version control system.
+
+== `git request-pull` introduction
+
+Here’s the raw output of a `git request-pull`:
+
+[source,sh]
+----
+$ git request-pull HEAD public-origin

+----
+
+That very first line is saying: "create me a pull request with only a single
+commit, defined by `HEAD`, and use the URL defined by `public-origin`".
+
+Here’s a pitfall: you may try using your `origin` remote at first where I put
+`public-origin`, but that is many times pointing to something like
+`git@example.com`, or `git.example.com:repo.git` (check that with
+`git remote -v | grep origin`).  On both cases those are addresses available for
+interaction via SSH, and it would be better if your pull requests used an
+address ready for public consumption.
+
+A simple solution for that is for you to add the `public-origin` alias as the
+HTTPS alternative to the SSH version:
+
+[source,sh]
+----
+$ git remote add public-origin https://example.com/user/repo
+----
+
+Every Git hosting provider exposes repositories via HTTPS.
+
+Experiment it yourself, and get acquainted with the CLI.
+
+== Delivering decentralized pull requests
+
+:cli-email: link:../04/cli-email-fun-profit.html
+
+Now that you can create the content of a pull request, you can just
+{cli-email}[deliver it] to the interested parties email:
+
+[source,sh]
+----
+# send a PR with your last commit to the author's email
+git request-pull HEAD public-origin | mail author@example.com -s "PR: Add thing to repo"
+
+# send a PR with your last 5 commits to the project's mailing
+# list, including the patch
+git request-pull -p HEAD~5 public-origin | \
+  mail list@example.com -s "PR: Add another thing to repo"
+
+# send every commit that is new in "other-branch"
+git request-pull master public-origin other-branch | \
+  mail list@example.com -s 'PR: All commits from my "other-brach"'
+----
+
+== Conclusion
+
+:distgit: https://drewdevault.com/2018/07/23/Git-is-already-distributed.html
+
+In practice, I’ve never used or seen anyone use pull requests this way:
+everybody is just {distgit}[sending patches via email].
+
+If you stop to think about this model, the problem of "Git hosting providers
+becoming too centralized" is a non-issue, and "Git federation" proposals are a
+less attractive as they may sound initially.
+
+Using Git this way is not scary or so weird as the first impression may suggest.
+It is actually how Git was designed to be used.
+
+Check `git help request-pull` for more info.

+git log -- *pattern*

+= DIY bare bones CI server with Bash and Nix
+:categories: ci
+:sort: 2
+
+:post-receive: https://git-scm.com/book/en/v2/Customizing-Git-Git-Hooks
+:example-project: https://euandreh.xyz/remembering/ci.html
+
+With a server with Nix installed (no need for NixOS), you can leverage its build
+isolation for running CI jobs by adding a {post-receive}[post-receive] Git hook
+to the server.
+
+In most of my project I like to keep a `test` attribute which runs the test with
+`nix-build -A test`.  This way, a post-receive hook could look like:
+
+[source,sh]
+----
+#!/usr/bin/env bash
+set -Eeuo pipefail
+set -x
+
+LOGS_DIR="/data/static/ci-logs/libedn"
+mkdir -p "$LOGS_DIR"
+LOGFILE="${LOGS_DIR}/$(date -Is)-$(git rev-parse master).log"
+exec &> >(tee -a "${LOGFILE}")
+
+unset GIT_DIR
+CLONE="$(mktemp -d)"
+git clone . "$CLONE"
+pushd "$CLONE"
+
+finish() {
+  printf "\n\n>>> exit status was %s\n" "$?"
+}
+trap finish EXIT
+
+nix-build -A test
+----
+
+We initially (lines #5 to #8) create a log file, named after _when_ the run is
+running and for _which_ commit it is running for.  The `exec` and `tee` combo
+allows the output of the script to go both to `stdout` _and_ the log file.  This
+makes the logs output show up when you do a `git push`.
+
+Lines #10 to #13 create a fresh clone of the repository and line #20 runs the
+test command.
+
+After using a similar post-receive hook for a while, I now even generate a
+simple HTML file to make the logs available ({example-project}[example project])
+through the browser.
+
+== Upsides
+
+No vendor lock-in, as all you need is a server with Nix installed.
+
+And if you pin the Nixpkgs version you're using, this very simple setup yields
+extremely sandboxed runs on a very hermetic environment.
+
+== Downsides
+
+Besides the many missing shiny features of this very simplistic CI, `nix-build`
+can be very resource intensive.  Specifically, it consumes too much memory.  So
+if it has to download too many things, or the build closure gets too big, the
+server might very well run out of memory.

+= Git bisect automation
+:categories: git
+:sort: 1
+
+It is good to have an standardized way to run builds and tests on the repository
+of a project, so that you can find when a bug was introduced by using
+`git bisect run`.
+
+I've already been in the situation when a bug was introduced and I didn't know
+how it even was occurring, and running Git bisect over hundreds of commits to
+pinpoint the failing commit was very empowering:
+
+[source,sh]
+----
+$ GOOD_COMMIT_SHA=e1fd0a817d192c5a5df72dd7422e36558fa78e46
+$ git bisect start HEAD $GOOD_COMMIT_SHA
+$ git bisect run sn -c './build.sh && ./run-failing-case.sh'
+----
+
+Git will than do a binary search between the commits, and run the commands you
+provide it with to find the failing commit.
+
+Instead of being afraid of doing a bisect, you should instead leverage it, and
+make Git help you dig through the history of the repository to find the bad
+code.

+
+{bash}[GNU Bash] has a few two letter variables that may be useful when typing
+on the terminal.
+
+== `!!`: the text of the last command
+
+The {bash-bang-bang}[`!!` variable] refers to the previous command, and I find
+useful when following chains for symlinks:
+
+[source,sh]
+----
+$ which git
+/run/current-system/sw/bin/git
+$ readlink $(!!)
+readlink $(which git)
+/nix/store/5bgr1xpm4m0r72h9049jbbhagxdyrnyb-git-2.28.0/bin/git
+----
+
+It is also useful when you forget to prefix `sudo` to a command that requires
+it:
+
+[source,sh]
+----
+$ requires-sudo.sh
+requires-sudo.sh: Permission denied
+$ sudo !!
+sudo ./requires-sudo.sh
+# all good
+----
+
+Bash prints the command expansion before executing it, so it is better for you
+to follow along what it is doing.
+
+== `$_`: most recent parameter
+
+The {bash-dollar-underscore}[`$_` variable] will give you the most recent
+parameter you provided to a previous argument, which can save you typing
+sometimes:
+
+[source,sh]
+----
+# instead of...
+$ mkdir -p a/b/c/d/
+$ cd a/b/c/d/
+
+# ...you can:
+$ mkdir -p a/b/c/d/
+$ cd $_
+----
+
+== Conclusion
+
+I wouldn't use those in a script, as it would make the script terser to read, I
+find those useful shortcut that are handy when writing at the interactive
+terminal.

+the previous article:
+
+[source,sh]
+----

+
+PREFIX='/srv/ci/vps'

+
+The important part is in the `finish()` function: - #25 stores the exit status
+and the generated filename separated by spaces; - #26 adds the log file in a
+note using the `refs/notes/ci-logs` ref; - #27 it adds a note to the commit
+saying how to see the logs.

+:shellcheck: https://www.shellcheck.net/
+
+Inspired by Fred Herbert's "{awk-20-min}[Awk in 20 Minutes]", here's a problem I
+just solved with a line of Awk: run ShellCheck in all scripts of a repository.
+
+In my repositories I usually have Bash and POSIX scripts, which I want to keep
+tidy with {shellcheck}[ShellCheck].  Here's the first version of
+`assert-shellcheck.sh`:
+
+[source,sh]
+----
+#!/bin/sh -eux
+
+find . -type f -name '*.sh' -print0 | xargs -0 shellcheck
+----
+
+This is the type of script that I copy around to all repositories, and I want it
+to be capable of working on any repository, without requiring a list of files to
+run ShellCheck on.
+
+This first version worked fine, as all my scripts had the `.sh' ending.  But I
+recently added some scripts without any extension, so `assert-shellcheck.sh`
+called for a second version.  The first attempt was to try grepping the shebang
+line:
+
+[source,sh]
+----
+$ grep '^#!/' assert-shellcheck.sh
+#!/usr/sh
+----
+
+Good, we have a grep pattern on the first try.  Let's try to find all the
+matching files:
+
+[source,sh]
+----
+$ find . -type f | xargs grep -l '^#!/'

+./scripts/generate-tasks-and-bugs.sh
+./scripts/songbooks.in
+./scripts/with-container.sh
+./scripts/assert-shellcheck.sh
+----
+
+This approach has a problem, though: it includes files ignored by Git, such as
+`builld-aux/install-sh~`, and even goes into the `.git/` directory and finds
+sample hooks in `.git/hooks/*`.
+
+To list the files that Git is tracking we'll try `git ls-files`:
+
+[source,sh]
+----
+$ git ls-files | xargs grep -l '^#!/'
+TODOs.org
+bootstrap
+build-aux/with-guile-env.in

+scripts/ci-build.sh
+scripts/compile-readme.sh
+scripts/generate-tasks-and-bugs.sh
+scripts/songbooks.in
+scripts/with-container.sh
+----
+
+It looks to be almost there, but the `TODOs.org` entry shows a flaw in it: grep
+is looking for a +'^#!/'+ pattern on any part of the file.  In my case,
+`TODOs.org` had a snippet in the middle of the file where a line started with
++#!/bin/sh+.
+
+So what we actually want is to match the *first* line against the pattern.  We
+could loop through each file, get the first line with `head -n 1` and grep
+against that, but this is starting to look messy.  I bet there is another way of
+doing it concisely...
+
+Let's try Awk.  I need a way to select the line numbers to replace `head -n 1`,
+and to stop processing the file if the pattern matches.  A quick search points
+me to using `FNR` for the former, and `{ nextline }` for the latter.  Let's try
+it:
+
+[source,sh]
+----
+$ git ls-files | xargs awk 'FNR>1 { nextfile } /^#!\// { print FILENAME; nextfile }'
+bootstrap
+build-aux/with-guile-env.in
+old/scripts/assert-docs-spelling.sh
+old/scripts/build-site.sh
+old/scripts/builder.bats.sh
+scripts/assert-shellcheck.sh
+scripts/assert-todos.sh
+scripts/ci-build.sh
+scripts/compile-readme.sh
+scripts/generate-tasks-and-bugs.sh
+scripts/songbooks.in
+scripts/with-container.sh
+----
+
+Great!  Only `TODOs.org` is missing, but the script is much better: instead of
+matching against any part of the file that may have a shebang-like line, we only
+look for the first.  Let's put it back into the `assert-shellcheck.sh` file and
+use `NULL` for separators to accommodate files with spaces in the name:
+
+[source,sh]
+----
+#!/usr/sh -eux
+
+git ls-files -z | \
+  xargs -0 awk 'FNR>1 { nextfile } /^#!\// { print FILENAME; nextfile }' | \
+  xargs shellcheck
+----
+
+This is where I've stopped, but I imagine a likely improvement: match against
+only +#!/bin/sh+ and +#!/usr/bin/env bash+ shebangs (the ones I use most), to
+avoid running ShellCheck on Perl files, or other shebangs.
+
+Also when reviewing the text of this article, I found that `{ nextfile }` is a
+GNU Awk extension.  It would be an improvement if `assert-shellcheck.sh` relied
+on the POSIX subset of Awk for working correctly.
+
+== _Update_
+
+After publishing, I could remove `{ nextfile }` and even make the script
+simpler:
+
+[source,sh]
+----
+#!/usr/sh -eux
+
+git ls-files -z | \
+  xargs -0 awk 'FNR==1 && /^#!\// { print FILENAME }' | \
+  xargs shellcheck
+----
+
+Now both the shell and Awk usage are POSIX compatible.

+= SVG favicon
+:updatedat: 2021-01-12
+
+:favicon: link:../../../../../img/favicon.svg
+
+I've wanted to change this website's favicon from a plain `.ico` file to a
+proper SVG.  The problem I was trying to solve was to reuse the same image on
+other places, such as avatars.
+
+Generating a PNG from the existing 16x16 icon was possible but bad: the final
+image was blurry.  Converting the `.ico` to an SVG was possible, but
+sub-optimal: tools try to guess some vector paths, and the final SVG didn't
+match the original.
+
+Instead I used a tool to draw the "vector pixels" as black squares, and after
+getting the final result I manually cleaned-up the generated XML:
+

+</svg>
+----
+
+The good thing about this new favicon (at {favicon}[`/static/lord-favicon.svg`])
+is that a) it is simple enough that I feel comfortable editing it manually and
+b) it is an SVG, which means I can generate any desired size.
+
+With the new favicon file, I now had to add to the templates' `<head>` a
+`<link>` to this icon:
+
+[source,html]
+----
+<head>
+  <meta charset="UTF-8" />
+  <link rel="icon" type="image/svg+xml" href="/static/favicon.svg">
+  ...
+----
+
+Still missing is a bitmap image for places that can't handle vector images.  I
+used Jekyll generator to create an PNG from the existing SVG:
+
+[source,ruby]
+----
+module Jekyll
+  class FaviconGenerator < Generator
+    safe true
+    priority :high
+
+    SIZE = 420
+
+    def generate(site)
+      svg = 'static/favicon.svg'
+      png = 'static/favicon.png'
+      unless File.exist? png then
+        puts "Missing '#{png}', generating..."
+        puts `inkscape -o #{png} -w #{SIZE} -h #{SIZE} #{svg}`
+      end
+    end
+  end
+end
+----
+
+I had to increase the priority of the generator so that it would run before
+other places that would use a `{% link /static/lord-favicon.png %}`, otherwise
+the file would be considered missing.

+= Awk snippet: send email to multiple recipients with cURL
+
+:neomutt: https://neomutt.org/
+:found-out-article: https://blog.edmdesigner.com/send-email-from-linux-command-line/
+:curl: https://curl.se/
+
+As I experiment with {neomutt}[Neomutt], I wanted to keep being able to enqueue
+emails for sending later like my previous setup, so that I didn't rely on having
+an internet connection.
+
+My requirements for the `sendmail` command were:
+
+. store the email in a file, and send it later;
+. send from different addresses, using different SMTP servers.
+
+I couldn't find an MTA that could accomplish that, but I was able to quickly
+write a solution.
+
+The first part was the easiest: store the email in a file:
+
+[source,sh]
+----
+# ~/.config/mutt/muttrc:
+set sendmail=~/bin/enqueue-email.sh
+
+# ~/bin/enqueue-email.sh:
+#!/bin/sh -eu
+
+cat - > "$HOME/mbsync/my-queued-emails/$(date -Is)"
+----
+
+Now that I had the email file store locally, I needed a program to send the
+email from the file, so that I could create a cronjob like:
+
+[source,sh]
+----
+for f in ~/mbsync/my-queued-emails/*; do
+  ~/bin/dispatch-email.sh "$f" && rm "$f"
+done
+----
+
+The `dispatch-email.sh` would have to look at the `From:` header and decide
+which SMTP server to use.  As I {found-out-article}[found out] that {curl}[curl]
+supports SMTP and is able to send emails, this is what I ended up with:
+
+[source,sh]
+----
+#!/bin/sh -eu
+
+F="$1"
+
+rcpt="$(awk '
+  match($0, /^(To|Cc|Bcc): (.*)$/, m) {
+    split(m[2], tos, ",")
+    for (i in tos) {
+      print "--mail-rcpt " tos[i]
+    }
+  }
+'  "$F")"
+
+if grep -qE '^From: .*<addr@server1\.org>$' "$F"; then
+  curl                                                      \
+    -s                                                      \
+    --url smtp://smtp.server1.org:587                       \
+    --ssl-reqd                                              \
+    --mail-from addr@server1.org                            \
+    $rcpt                                                   \
+    --user 'addr@server1.org:my-long-and-secure-passphrase' \
+    --upload-file "$F"
+elif grep -qE '^From: .*<addr@server2\.org>$' "$F"; then
+  curl                                                      \
+    -s                                                      \
+    --url smtp://smtp.server2.org:587                       \
+    --ssl-reqd                                              \
+    --mail-from addr@server2.org                            \
+    $rcpt                                                   \
+    --user 'addr@server2.org:my-long-and-secure-passphrase' \
+    --upload-file "$F"
+else
+  echo 'Bad "From: " address'
+  exit 1
+fi
+----
+
+Most of curl flags used are self-explanatory, except for `$rcpt`.
+
+curl connects to the SMTP server, but doesn't set the recipient address by
+looking at the message.  My solution was to generate the curl flags, store them
+in `$rcpt` and use it unquoted to leverage shell word splitting.
+
+To me, the most interesting part was building the `$rcpt` flags.  My first
+instinct was to try grep, but it couldn't print only matches in a regex.  As I
+started to turn towards sed, I envisioned needing something else to loop over
+the sed output, and I then moved to Awk.
+
+In the short Awk snippet, 3 things were new to me: the `match(...)`,
+`split(...)` and `for () {}`.  The only other function I have ever used was
+`gsub(...)`, but these new ones felt similar enough that I could almost guess
+their behaviour and arguments.  `match(...)` stores the matches of a regex on
+the given array positionally, and `split(...)` stores the chunks in the given
+array.
+
+I even did it incrementally:
+
+[source,sh]
+----
+$ H='To: to@example.com, to2@example.com\nCc: cc@example.com, cc2@example.com\nBcc: bcc@example.com,bcc2@example.com\n'
+$ printf "$H" | awk '/^To: .*$/ { print $0 }'
+To: to@example.com, to2@example.com
+$ printf "$H" | awk 'match($0, /^To: (.*)$/, m) { print m }'
+awk: ligne de commande:1: (FILENAME=- FNR=1) fatal : tentative d'utilisation du tableau « m » dans un contexte scalaire
+$ printf "$H" | awk 'match($0, /^To: (.*)$/, m) { print m[0] }'
+To: to@example.com, to2@example.com
+$ printf "$H" | awk 'match($0, /^To: (.*)$/, m) { print m[1] }'
+to@example.com, to2@example.com
+$ printf "$H" | awk 'match($0, /^To: (.*)$/, m) { split(m[1], tos, " "); print tos }'
+awk: ligne de commande:1: (FILENAME=- FNR=1) fatal : tentative d'utilisation du tableau « tos » dans un contexte scalaire
+$ printf "$H" | awk 'match($0, /^To: (.*)$/, m) { split(m[1], tos, " "); print tos[0] }'
+
+$ printf "$H" | awk 'match($0, /^To: (.*)$/, m) { split(m[1], tos, " "); print tos[1] }'
+to@example.com,
+$ printf "$H" | awk 'match($0, /^To: (.*)$/, m) { split(m[1], tos, " "); print tos[2] }'
+to2@example.com
+$ printf "$H" | awk 'match($0, /^To: (.*)$/, m) { split(m[1], tos, " "); print tos[3] }'
+----
+
+(This isn't the verbatim interactive session, but a cleaned version to make it
+more readable.)
+
+At this point, I realized I needed a for loop over the `tos` array, and I moved
+the Awk snippet into the `~/bin/dispatch-email.sh`.  I liked the final thing:
+
+[source,awk]
+----
+match($0, /^(To|Cc|Bcc): (.*)$/, m) {
+  split(m[2], tos, ",")
+  for (i in tos) {
+    print "--mail-rcpt " tos[i]
+  }
+}
+----
+
+As I learn more about Awk, I feel that it is too undervalued, as many people
+turn to Perl or other programming languages when Awk suffices.  The advantage is
+pretty clear: writing programs that run on any POSIX system, without extra
+dependencies required.
+
+Coding to the standards is underrated.

+= POSIX sh and shebangs
+
+:awk-1: link:../../../2020/12/15/shellcheck-repo.html
+:awk-2: link:../12/curl-awk-emails.html
+
+As I {awk-1}[keep moving] {awk-2}[towards POSIX], I'm on the process of
+migrating all my Bash scripts to POSIX sh.
+
+As I dropped `[[`, arrays and other Bashisms, I was left staring at the first
+line of every script, wondering what to do: what is the POSIX sh equivalent of
+`#!/usr/bin/env bash`?  I already knew that POSIX says nothing about shebangs,
+and that the portable way to call a POSIX sh script is `sh script.sh`, but
+I didn't know what to do with that first line.
+
+What I had previously was:
+
+[source,sh]
+----
+#!/usr/bin/env bash
+set -Eeuo pipefail
+cd "$(dirname "${BASH_SOURCE[0]}")"
+----
+
+Obviously, the `$BASH_SOURCE` would be gone, and I would have to adapt some of
+my scripts to not rely on the script location.  The `-E` and `-o pipefail`
+options were also gone, and would be replaced by nothing.
+
+I converted all of them to:
+
+[source,sh]
+----
+#!/bin/sh -eu
+----
+
+I moved the `-eu` options to the shebang line itself, striving for conciseness.
+But as I changed callers from `./script.sh` to `sh script.sh`, things started to
+fail.  Some tests that should fail reported errors, but didn't return 1.
+
+My first reaction was to revert back to `./script.sh`, but the POSIX bug I
+caught is a strong strain, and when I went back to it, I figured that the
+callers were missing some flags.  Specifically, `sh -eu script.sh`.
+
+Then it clicked: when running with `sh script.sh`, the shebang line with the sh
+options is ignored, as it is a comment!
+
+Which means that the shebang most friendly with POSIX is:
+
+[source,sh]
+----
+#!/bin/sh
+set -eu
+----
+
+. when running via `./script.sh`, if the system has an executable at `/bin/sh`,
+  it will be used to run the script;
+. when running via `sh script.sh`, the sh options aren't ignored as previously.
+
+TIL.

+
+CLOS uses a similar logic when choosing the method from parent classes, when
+multiple ones are available:
+
+[source,lisp]
+----
+* (defclass class-a () ())
+
+#<STANDARD-CLASS CLASS-A {583E0B25}>
+* (defclass class-b () ())
+
+#<STANDARD-CLASS CLASS-B {583E7F6D}>
+* (defgeneric another-fn (obj))
+
+#<STANDARD-GENERIC-FUNCTION ANOTHER-FN (0) {583DA749}>
+* (defmethod another-fn ((obj class-a)) :class-a)
+; Compiling LAMBDA (.PV-CELL. .NEXT-METHOD-CALL. OBJ):
+; Compiling Top-Level Form:
+
+#<STANDARD-METHOD ANOTHER-FN (CLASS-A) {584523C5}>
+* (defmethod another-fn ((obj class-b)) :class-b)
+; Compiling LAMBDA (.PV-CELL. .NEXT-METHOD-CALL. OBJ):
+; Compiling Top-Level Form:
+
+#<STANDARD-METHOD ANOTHER-FN (CLASS-B) {584B8895}>
+----
+
+Given the above definitions, when inheriting from `class-a` and `class-b`, the
+order of inheritance matters:
+
+[source,lisp]
+----
+* (defclass class-a-coming-first (class-a class-b) ())
+#<STANDARD-CLASS CLASS-A-COMING-FIRST {584BE6AD}>
+
+* (defclass class-b-coming-first (class-b class-a) ())
+#<STANDARD-CLASS CLASS-B-COMING-FIRST {584C744D}>
+
+* (another-fn (make-instance 'class-a-coming-first))
+:CLASS-A
+
+* (another-fn (make-instance 'class-b-coming-first))
+:CLASS-B
+----
+
+Combining the order of inheritance with generic functions with multiple
+arguments, CLOS has to make a choice of how to pick a method given two competing
+definitions, and its default strategy is prioritizing from left to right:
+
+[source,lisp]
+----
+* (defgeneric yet-another-fn (obj1 obj2))
+#<STANDARD-GENERIC-FUNCTION YET-ANOTHER-FN (0) {584D9EC9}>
+
+* (defmethod yet-another-fn ((obj1 class-a) obj2) :first-arg-specialized)
+#<STANDARD-METHOD YET-ANOTHER-FN (CLASS-A T) {5854269D}>
+
+* (defmethod yet-another-fn (obj1 (obj2 class-b)) :second-arg-specialized)
+#<STANDARD-METHOD YET-ANOTHER-FN (T CLASS-B) {585AAAAD}>
+
+* (yet-another-fn (make-instance 'class-a) (make-instance 'class-b))
+:FIRST-ARG-SPECIALIZED
+----
+
+CLOS has to make a choice between the first and the second definition of
+`yet-another-fn`, but its choice is just a heuristic.  What if we want the
+choice to be based on the second argument, instead of the first?
+
+For that, we use the `:argument-precedence-order` option when declaring a
+generic function:
+
+[source,lisp]
+----
+* (defgeneric yet-another-fn (obj1 obj2) (:argument-precedence-order obj2 obj1))
+#<STANDARD-GENERIC-FUNCTION YET-ANOTHER-FN (2) {584D9EC9}>
+
+* (yet-another-fn (make-instance 'class-a) (make-instance 'class-b))
+:SECOND-ARG-SPECIALIZED
+----
+
+I liked that the `:argument-precedence-order` option exists.  We shouldn't have
+to change the arguments from `(obj1 obj2)` to `(obj2 obj1)` just to make CLOS
+pick the method that we want.  We can configure its default behaviour if
+desired, and keep the order of arguments however it best fits the generic
+function.
+
+== Comparison with Clojure
+
+Clojure has an equivalent, when using `defmulti`.
+
+Since when declaring a multi-method with `defmulti` we must define the dispatch
+function, Clojure uses it to pick the method definition.  Since the dispatch
+function is required, there is no need for a default behaviour, such as
+left-to-right.
+
+== Conclusion
+
+Making the argument precedence order configurable for generic functions but not
+for class definitions makes a lot of sense.
+
+When declaring a class, we can choose the precedence order, and that is about
+it.  But when defining a generic function, the order of arguments is more
+important to the function semantics, and the argument precedence being
+left-to-right is just the default behaviour.
+
+One shouldn't change the order of arguments of a generic function for the sake
+of tailoring it to the CLOS priority ranking algorithm, but doing it for a class
+definition is just fine.

+= Clojure auto curry
+:sort: 1
+:updatedat: 2021-04-27
+
+:defcurry-orig: https://lorettahe.github.io/clojure/2016/09/22/clojure-auto-curry
+
+Here's a simple macro defined by {defcurry-orig}[Loretta He] to create Clojure
+functions that are curried on all arguments, relying on Clojure's multi-arity
+support:
+
+[source,clojure]
+----
+(defmacro defcurry
+  [name args & body]
+  (let [partials (map (fn [n]
+                        `(~(subvec args 0 n) (partial ~name ~@(take n args))))
+                      (range 1 (count args)))]
+    `(defn ~name
+       (~args ~@body)
+       ~@partials)))
+----
+
+A naive `add` definition, alongside its usage and macroexpansion:
+
+[source,clojure]
+----
+user=> (defcurry add
+         [a b c d e]
+         (+ 1 2 3 4 5))
+#'user/add
+
+user=> (add 1)
+#object[clojure.core$partial$fn__5857 0x2c708440 "clojure.core$partial$fn__5857@2c708440"]
+
+user=> (add 1 2 3 4)
+#object[clojure.core$partial$fn__5863 0xf4c0e4e "clojure.core$partial$fn__5863@f4c0e4e"]
+
+user=> ((add 1) 2 3 4 5)
+15
+
+user=> (((add 1) 2 3) 4 5)
+15
+
+user=> (use 'clojure.pprint)
+nil
+
+user=> (pprint
+        (macroexpand
+         '(defcurry add
+            [a b c d e]
+            (+ 1 2 3 4 5))))
+(def
+ add
+ (clojure.core/fn
+  ([a b c d e] (+ 1 2 3 4 5))
+  ([a] (clojure.core/partial add a))
+  ([a b] (clojure.core/partial add a b))
+  ([a b c] (clojure.core/partial add a b c))
+  ([a b c d] (clojure.core/partial add a b c d))))
+nil
+----
+
+This simplistic `defcurry` definition doesn't support optional parameters,
+multi-arity, `&` rest arguments, docstrings, etc., but it could certainly evolve
+to do so.
+
+I like how `defcurry` is so short, and abdicates the responsability of doing the
+multi-arity logic to Clojure's built-in multi-arity support.  Simple and
+elegant.
+
+Same Clojure as before, now with auto-currying via macros.
+
+== Comparison with Common Lisp
+
+My attempt at writing an equivalent for Common Lisp gives me:
+
+[source,lisp]
+----
+(defun partial (fn &rest args)
+  (lambda (&rest args2)
+    (apply fn (append args args2))))
+
+(defun curry-n (n func)
+  (cond ((< n 0) (error "Too many arguments"))
+        ((zerop n) (funcall func))
+        (t (lambda (&rest rest)
+             (curry-n (- n (length rest))
+                      (apply #'partial func rest))))))
+
+(defmacro defcurry (name args &body body)
+  `(defun ,name (&rest rest)
+     (let ((func (lambda ,args ,@body)))
+       (curry-n (- ,(length args) (length rest))
+                (apply #'partial func rest)))))
+----
+
+Without built-in multi-arity support, we have to do more work, like tracking the
+number of arguments consumed so far.  We also have to write `#'partial`
+ourselves.  That is, without dependending on any library, sticking to ANSI
+Common Lisp.
+
+The usage is pretty similar:
+
+[source,lisp]
+----
+* (defcurry add (a b c d e)
+    (+ a b c d e))
+ADD
+
+* (add 1)
+#<FUNCTION (LAMBDA (&REST REST) :IN CURRY-N) {100216419B}>
+
+* (funcall (add 1) 2 3 4)
+#<FUNCTION (LAMBDA (&REST REST) :IN CURRY-N) {100216537B}>
+
+* (funcall (add 1) 2 3 4 5)
+15
+
+* (funcall (funcall (add 1) 2 3) 4 5)
+15
+
+* (macroexpand-1
+    '(defcurry add (a b c d e)
+       (+ a b c d e)))
+(DEFUN ADD (&REST REST)
+  (LET ((FUNC (LAMBDA (A B C D E) (+ A B C D E))))
+    (CURRY-N (- 5 (LENGTH REST)) (APPLY #'PARTIAL FUNC REST))))
+T
+----
+
+This also require `funcall`s, since we return a `lambda` that doesn't live in
+the function namespace.
+
+Like the Clojure one, it doesn't support optional parameters, `&rest` rest
+arguments, docstrings, etc., but it also could evolve to do so.

+= Three-way conditional for number signs on Lisp
+:categories: lisp scheme common-lisp
+:sort: 2

+
+:on-lisp: https://www.paulgraham.com/onlisptext.html
+:sicp: https://mitpress.mit.edu/sites/default/files/sicp/index.html
+
+A useful macro from Paul Graham's {on-lisp}[On Lisp] book:
+
+[source,lisp]
+----
+(defmacro nif (expr pos zero neg)
+  (let ((g (gensym)))
+    `(let ((,g ,expr))
+       (cond ((plusp ,g) ,pos)
+             ((zerop ,g) ,zero)
+             (t ,neg)))))
+----
+
+After I looked at this macro, I started seeing opportunities to using it in many
+places, and yet I didn't see anyone else using it.
+
+The latest example I can think of is section 1.3.3 of {sicp}[Structure and
+Interpretation of Computer Programs], which I was reading recently:
+
+[source,scheme]
+----
+(define (search f neg-point pos-point)
+  (let ((midpoint (average neg-point pos-point)))
+    (if (close-enough? neg-point post-point)
+        midpoint
+        (let ((test-value (f midpoint)))
+          (cond ((positive? test-value)
+                 (search f neg-point midpoint))
+                ((negative? test-value)
+                 (search f midpoint pos-point))
+                (else midpoint))))))
+----
+
+Not that the book should introduce such macro this early, but I couldn't avoid
+feeling bothered by not using the `nif` macro, which could even remove the need
+for the intermediate `test-value` variable:
+
+[source,scheme]
+----
+(define (search f neg-point pos-point)
+  (let ((midpoint (average neg-point pos-point)))
+    (if (close-enough? neg-point post-point)
+        midpoint
+        (nif (f midpoint)
+             (search f neg-point midpoint)
+             (midpoint)
+             (search f midpoint pos-point)))))
+----
+
+It also avoids `cond`'s extra clunky parentheses for grouping, which is
+unnecessary but built-in.
+
+As a macro, I personally feel it tilts the balance towards expressivenes despite
+its extra cognitive load toll.

+----
+
+On the first line we import the public key (funnily enough, available via
+HTTPS), and after cloning the code via the insecure `git://` protocol, we use
+`git verify-commit` to check the signature.
+
+The verification is successful, and we can see that the public key from the
+signature matches the fingerprint of the imported one.  However
+`git verify-commit` doesn't have an option to check which public key you want to
+verify the commit against.  Which means that if a MITM attack happens, the
+attacker could very easily serve a malicious repository with signed commits, and
+you'd have to verify the public key by yourself.  That would need to happen for
+subsequent fetches, too.
+
+Even though this is possible, it is not very convenient, and certainly very
+brittle.  Despite the fact that the Git Protocol is much faster, it being harder
+to make secure is a big downside.

+= Encoding and decoding JavaScript BigInt values with reviver
+:updatedat: 2021-08-13
+
+:reviver-fn: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse#using_the_reviver_parameter

+:json-rfc: https://datatracker.ietf.org/doc/html/rfc8259
+
+`JSON.parse()` accepts a second parameter: a {reviver-fn}[`reviver()` function].
+It is a function that can be used to transform the `JSON` values as they're
+being parsed.
+
+As it turns out, when combined with JavaScript's {bigint}[`BigInt`] type, you
+can parse and encode JavaScript `BigInt` numbers via JSON:
+
+[source,javascript]
+----
+const bigIntReviver = (_, value) =>
+    typeof value === "string" && value.match(/^-?[0-9]+n$/)
+        ? BigInt(value.slice(0, value.length - 1))
+        : value;
+----
+
+I chose to interpret strings that contains only numbers and an ending `n`
+suffix as `BigInt` values, similar to how JavaScript interprets `123` (a number)
+differently from `123n` (a `bigint`);
+
+We do those checks before constructing the `BigInt` to avoid throwing needless
+exceptions and catching them on the parsing function, as this could easily
+become a bottleneck when parsing large JSON values.
+
+In order to do the full roundtrip, we now only need the `toJSON()` counterpart:
+
+[source,javascript]
+----
+BigInt.prototype.toJSON = function() {
+    return this.toString() + "n";
+};
+----
+
+With both `bigIntReviver` and `toJSON` defined, we can now successfully parse
+and encode JavaScript objects with `BigInt` values transparently:
+
+[source,javascript]
+----
+const s = `[
+    null,
+    true,
+    false,
+    -1,
+    3.14,
+    "a string",
+    { "a-number": "-123" },
+    { "a-bigint": "-123n" }
+]`;
+
+const parsed = JSON.parse(s, bigIntReviver);
+const s2 = JSON.stringify(parsed);
+
+console.log(parsed);
+console.log(s2);
+
+console.log(typeof parsed[6]["a-number"])
+console.log(typeof parsed[7]["a-bigint"])
+----
+
+The output of the above is:
+
+[source,javascript]
+----
+[
+  null,
+  true,
+  false,
+  -1,
+  3.14,
+  'a string',
+  { 'a-number': '-123' },
+  { 'a-bigint': -123n }
+]
+[null,true,false,-1,3.14,"a string",{"a-number":"-123"},{"a-bigint":"-123n"}]
+string
+bigint
+----
+
+If you're on a web browser, you can probably try copying and pasting the above
+code on the console right now, as is.
+
+Even though {json-rfc}[`JSON`] doesn't include `BigInt` number, encoding and
+decoding them as strings is quite trivial on JavaScript.

-
-All I did was to wrap the header tag inside an `<a>`, and set the `href` of that
-`<a>` to the existing id of the header.  Before the hook the HTML looks like:
-
-[source,html]
-----
-...some unmodified text...
-<h2 id="my-header">
-  My header
-</h2>
-...more unmodified text...
-----
-
-And after the hook should turn that into:

-<a href="#my-header">
-  <h2 id="my-header">
-    My header
-  </h2>
-</a>
-...more unmodified text...

-
-The used regexp tries to match only h1-h6 tags, and keep the rest of the HTML
-attributes untouched, since this isn't a general HTML parser, but the generated
-HTML is somewhat under your control.  Use at your own risk because
-{html-regex}[you shouldn't parse HTML with regexps].  Also I used this strategy
-in my environment, where no other plugins are installed.  I haven't considered
-how this approach may conflict with other Jekyll plugins.

-In the new anchor tag you can add your custom CSS class to style it as you wish.
-
-== Anchor on code blocks
-
-Adding anchors to code blocks needs a little bit of extra work, because line
-numbers themselves don't have preexisting ids, so we need to generate them
-without duplications between multiple code blocks in the same page.
-
-Similarly, this Jekyll hook also works on `:documents` in the `:post_render`
-phase:
-
-[source,ruby]
-----
-PREFIX = '<pre class="lineno">'
-POSTFIX = '</pre>'
-Jekyll::Hooks.register :documents, :post_render do |doc|
-  if doc.output_ext == ".html"
-    code_block_counter = 1
-    doc.output = doc.output.gsub(/<pre class="lineno">[\n0-9]+<\/pre>/) do |match|
-      line_numbers = match
-                      .gsub(/<pre class="lineno">([\n0-9]+)<\/pre>/, '\1')
-                      .split("\n")
-
-      anchored_line_numbers_array = line_numbers.map do |n|
-        id = "B#{code_block_counter}-L#{n}"
-        "<a id=\"#{id}\" href=\"##{id}\">#{n}</a>"
-      end
-      code_block_counter += 1
-
-      PREFIX + anchored_line_numbers_array.join("\n") + POSTFIX
-    end
-  end
-end
-----
-
-This solution assumes the default Jekyll toolbox with code line numbers turned
-on in `_config.yml`:
-
-[source,yaml]
-----
-kramdown:
-  syntax_highlighter_opts:
-    span:
-      line_numbers: false
-    block:
-      line_numbers: true
-----
-
-The anchors go from B1-L1 to BN-LN, using the `code_block_counter` to track
-which code block we're in and don't duplicate anchor ids.  Before the hook the
-HTML looks like:
-
-[source,html]
-----
-...some unmodified text...
-<pre class="lineno">1
-2
-3
-4
-5
-</pre>
-...more unmodified text...
-----

-= Browse a git repository at a specific commit
-:categories: git
-
-I commonly use tools like `git log` together with `git show` when inspecting
-past changes in a repository:
-
-[source,sh]
-----
-git log
-# search for a the commit I'm looking for
-git show <my-commit>
-# see the diff for the commit
-----
-
-But I also wanted to not only be able to look at the diff of a specific commit,
-but to browse the whole repository at that specific commit.
-
-I used to accomplish it the "brute force" way: clone the whole repository in
-another folder and checkout the commit there:
-
-[source,sh]
-----
-git clone <original-repo> /tmp/tmp-repo-clone
-cd /tmp-repo-clone
-git checkout <my-commit>
-----
-
-But git itself allows we to specific the directory of the checkout by using the
-`--work-tree` global git flag.  This is what `man git` says about it:
-
-[source,text]
-----
---work-tree=<path>
-    Set the path to the working tree. It can be an absolute path or a path relative to the current working
-    directory. This can also be controlled by setting the GIT_WORK_TREE environment variable and the
-    core.worktree configuration variable (see core.worktree in git-config(1) for a more detailed
-    discussion).
-----
-
-So it allows us to set the desired path of the working tree.  So if we want to
-copy the contents of the current working tree into `copy/`:
-
-[source,sh]
-----
-mkdir copy
-git --work-tree=copy/ checkout .
-----
-
-After that `copy/` will contain a replica of the code in HEAD.  But to checkout
-a specific, we need some extra parameters:
-
-[source,sh]
-----
-git --work-tree=<dir> checkout <my-commit> -- .
-----
-
-There's an extra `-- .` at the end, which initially looks like we're sending
-Morse signals to git, but we're actually saying to `git-checkout` which sub
-directory of `<my-commit>` we want to look at.  Which means we can do something
-like:
-
-[source,sh]
-----
-git --work-tree=<dir> checkout <my-commit> -- src/
-----
-
-And with that `<dir>` will only contain what was inside `src/` at `<commit>`.
-
-After any of those checkouts, you have to `git reset .` to reset your current
-staging area back to what it was before the checkout.

-git show
-# shows the latest commit
-git show <commit>
-# shows an specific <commit>
-git show v1.2
-# shows commit tagged with v1.2

-
-== 2. `git log --grep='<regexp>'`
-
-Search through the commit messages:
-
-[source,sh]
-----
-git log --grep='refactor'
-----
-
-== 3. `git grep '<regexp>' [commit]`
-
-:browse-article: link:../14/browse-git.html
-
-Search content in git history:
-
-[source,sh]
-----
-git grep 'TODO'
-# search the repository for the "TODO" string
-git grep 'TODO' $(git rev-list --all)
-# search the whole history for "TODO" string
-----
-
-And if you find an occurrence of the regexp in a specific commit and you want to
-browse the repository in that point in time, you can {browse-article}[use git
-checkout for that].

-= Grep online repositories
-:categories: git
-
-:cgit: https://git.zx2c4.com/cgit/
-
-I often find interesting source code repositories online that I want to grep for
-some pattern but I can't, because either:
-
-* the repository is on {cgit}[cgit] or a similar code repository that doesn't
-  allow search in files, or;
-* the search function is really bad, and doesn't allow me to use regular
-  expressions for searching patterns in the code.
-
-Here's a simple script that allows you to overcome that problem easily:
-
-[source,sh]
-----
-#!/usr/bin/env bash
-set -eu
-
-end="\033[0m"
-red="\033[0;31m"
-red() { echo -e "${red}${1}${end}"; }
-
-usage() {
-  red "Missing argument $1.\n"
-  cat <<EOF
-Usage:
-    $0 <REGEX_PATTERN> <REPOSITORY_URL>
-
-      Arguments:
-        REGEX_PATTERN     Regular expression that "git grep" can search
-        REPOSITORY_URL    URL address that "git clone" can download the repository from
-
-Examples:
-    Searching "make get-git" in cgit repository:
-        git search 'make get-git' https://git.zx2c4.com/cgit/
-        git search 'make get-git' https://git.zx2c4.com/cgit/ -- \$(git rev-list --all)

-fi
-pushd "/tmp/git-search/${DIRNAME}"
-
-shift 3 || shift 2 # when "--" is missing
-git grep "${REGEX_PATTERN}" "${@}"
-----
-
-It is a wrapper around `git grep` that downloads the repository when missing.
-Save in a file called `git-search`, make the file executable and add it to your
-path.
-
-Overview:
-
-* _lines 1~2_:
-+
-Bash shebang and the `set -eu` options to exit on error or undefined
-variables.
-
-* _lines 4~30_:
-+
-Usage text to be printed when providing less arguments than expected.
-
-* _line 33_:
-+
-Extract the repository name from the URL, removing trailing slashes.
-
-* _lines 34~37_:
-+
-Download the repository when missing and go to the folder.
-
-* _line 39_:
-+
-Make the variable `$@` contain the rest of the unused arguments.
-
-* _line 40_:
-+
-Perform `git grep`, forwarding the remaining arguments from `$@`.
-
-Example output:

-= Pull requests with Git, the old school way
-:categories: git
-
-:empty:
-:cgit: https://git.zx2c4.com/cgit/
-
-It might be news to you, as it was to me, that "pull requests" that you can
-create on a Git hosting provider’s web
-UI{empty}footnote:pr-webui[
-  And maybe even using the Git hosting provider’s API from the command line!
-] like GitLab/Bitbucket/GitHub actually comes from Git itself:
-`git request-pull`.
-
-At the very core, they accomplish the same thing: both the original and the web
-UI ones are ways for you to request the project maintainers to pull in your
-changes from your fork.  It’s like saying: "hi there, I did some changes on my
-clone of the repository, what do you think about bringing those in?".
-
-The only difference is that you’re working with only Git itself, so you’re not
-tied to any Git hosting provider: you can send pull requests across them
-transparently!  You could even use your own {cgit}[cgit] installation.  No need
-to be locked in by any of them, putting the "D" back in "DVCS": it’s a
-*distributed* version control system.
-
-== `git request-pull` introduction
-
-Here’s the raw output of a `git request-pull`:
-
-[source,sh]
-----
-$ git request-pull HEAD public-origin
-The following changes since commit 302c9f2f035c0360acd4e13142428c100a10d43f:

- 1 file changed, 6 insertions(+), 6 deletions(-)
-----
-
-That very first line is saying: "create me a pull request with only a single
-commit, defined by `HEAD`, and use the URL defined by `public-origin`".
-
-Here’s a pitfall: you may try using your `origin` remote at first where I put
-`public-origin`, but that is many times pointing to something like
-`git@example.com`, or `git.example.com:repo.git` (check that with
-`git remote -v | grep origin`).  On both cases those are addresses available for
-interaction via SSH, and it would be better if your pull requests used an
-address ready for public consumption.
-
-A simple solution for that is for you to add the `public-origin` alias as the
-HTTPS alternative to the SSH version:
-
-[source,sh]
-----
-$ git remote add public-origin https://example.com/user/repo
-----
-
-Every Git hosting provider exposes repositories via HTTPS.
-
-Experiment it yourself, and get acquainted with the CLI.
-
-== Delivering decentralized pull requests
-
-:cli-email: link:../04/cli-email-fun-profit.html
-
-Now that you can create the content of a pull request, you can just
-{cli-email}[deliver it] to the interested parties email:
-
-[source,sh]
-----
-# send a PR with your last commit to the author's email
-git request-pull HEAD public-origin | mail author@example.com -s "PR: Add thing to repo"
-
-# send a PR with your last 5 commits to the project's mailing
-# list, including the patch
-git request-pull -p HEAD~5 public-origin | \
-  mail list@example.com -s "PR: Add another thing to repo"
-
-# send every commit that is new in "other-branch"
-git request-pull master public-origin other-branch | \
-  mail list@example.com -s 'PR: All commits from my "other-brach"'
-----
-
-== Conclusion
-
-:distgit: https://drewdevault.com/2018/07/23/Git-is-already-distributed.html
-
-In practice, I’ve never used or seen anyone use pull requests this way:
-everybody is just {distgit}[sending patches via email].
-
-If you stop to think about this model, the problem of "Git hosting providers
-becoming too centralized" is a non-issue, and "Git federation" proposals are a
-less attractive as they may sound initially.
-
-Using Git this way is not scary or so weird as the first impression may suggest.
-It is actually how Git was designed to be used.
-
-Check `git help request-pull` for more info.

-In most of my project I like to keep a `test` attribute which runs the test with
-`nix-build -A test`.  This way, a post-receive hook could look like:
-
-[source,sh]
-----
-#!/usr/bin/env bash
-set -Eeuo pipefail
-set -x
-
-LOGS_DIR="/data/static/ci-logs/libedn"
-mkdir -p "$LOGS_DIR"
-LOGFILE="${LOGS_DIR}/$(date -Is)-$(git rev-parse master).log"
-exec &> >(tee -a "${LOGFILE}")
-
-unset GIT_DIR
-CLONE="$(mktemp -d)"
-git clone . "$CLONE"
-pushd "$CLONE"
-
-finish() {
-  printf "\n\n>>> exit status was %s\n" "$?"
-}
-trap finish EXIT
-
-nix-build -A test
-----
-
-We initially (lines #5 to #8) create a log file, named after _when_ the run is
-running and for _which_ commit it is running for.  The `exec` and `tee` combo
-allows the output of the script to go both to `stdout` _and_ the log file.  This
-makes the logs output show up when you do a `git push`.
-
-Lines #10 to #13 create a fresh clone of the repository and line #20 runs the
-test command.
-
-After using a similar post-receive hook for a while, I now even generate a
-simple HTML file to make the logs available ({example-project}[example project])
-through the browser.
-
-== Upsides
-
-No vendor lock-in, as all you need is a server with Nix installed.
-
-And if you pin the Nixpkgs version you're using, this very simple setup yields
-extremely sandboxed runs on a very hermetic environment.
-
-== Downsides
-
-Besides the many missing shiny features of this very simplistic CI, `nix-build`
-can be very resource intensive.  Specifically, it consumes too much memory.  So
-if it has to download too many things, or the build closure gets too big, the
-server might very well run out of memory.

-= Git bisect automation
-:categories: git
-:sort: 1
-
-It is good to have an standardized way to run builds and tests on the repository
-of a project, so that you can find when a bug was introduced by using
-`git bisect run`.
-
-I've already been in the situation when a bug was introduced and I didn't know
-how it even was occurring, and running Git bisect over hundreds of commits to
-pinpoint the failing commit was very empowering:
-
-[source,sh]
-----
-$ GOOD_COMMIT_SHA=e1fd0a817d192c5a5df72dd7422e36558fa78e46
-$ git bisect start HEAD $GOOD_COMMIT_SHA
-$ git bisect run sn -c './build.sh && ./run-failing-case.sh'
-----
-
-Git will than do a binary search between the commits, and run the commands you
-provide it with to find the failing commit.
-
-Instead of being afraid of doing a bisect, you should instead leverage it, and
-make Git help you dig through the history of the repository to find the bad
-code.

-
-{bash}[GNU Bash] has a few two letter variables that may be useful when typing
-on the terminal.
-
-== `!!`: the text of the last command
-
-The {bash-bang-bang}[`!!` variable] refers to the previous command, and I find
-useful when following chains for symlinks:
-
-[source,sh]
-----
-$ which git
-/run/current-system/sw/bin/git
-$ readlink $(!!)
-readlink $(which git)
-/nix/store/5bgr1xpm4m0r72h9049jbbhagxdyrnyb-git-2.28.0/bin/git
-----
-
-It is also useful when you forget to prefix `sudo` to a command that requires
-it:
-
-[source,sh]
-----
-$ requires-sudo.sh
-requires-sudo.sh: Permission denied
-$ sudo !!
-sudo ./requires-sudo.sh
-# all good
-----
-
-Bash prints the command expansion before executing it, so it is better for you
-to follow along what it is doing.
-
-== `$_`: most recent parameter
-
-The {bash-dollar-underscore}[`$_` variable] will give you the most recent
-parameter you provided to a previous argument, which can save you typing
-sometimes:
-
-[source,sh]
-----
-# instead of...
-$ mkdir -p a/b/c/d/
-$ cd a/b/c/d/
-
-# ...you can:
-$ mkdir -p a/b/c/d/
-$ cd $_
-----
-
-== Conclusion
-
-I wouldn't use those in a script, as it would make the script terser to read, I
-find those useful shortcut that are handy when writing at the interactive
-terminal.

-= Awk snippet: ShellCheck all scripts in a repository
-:categories: shell
-:updatedat: 2020-12-16
-
-:awk-20-min: https://ferd.ca/awk-in-20-minutes.html
-:shellcheck: https://www.shellcheck.net/
-
-Inspired by Fred Herbert's "{awk-20-min}[Awk in 20 Minutes]", here's a problem I
-just solved with a line of Awk: run ShellCheck in all scripts of a repository.
-
-In my repositories I usually have Bash and POSIX scripts, which I want to keep
-tidy with {shellcheck}[ShellCheck].  Here's the first version of
-`assert-shellcheck.sh`:
-
-[source,sh]
-----
-#!/bin/sh -eux
-
-find . -type f -name '*.sh' -print0 | xargs -0 shellcheck
-----
-
-This is the type of script that I copy around to all repositories, and I want it
-to be capable of working on any repository, without requiring a list of files to
-run ShellCheck on.
-
-This first version worked fine, as all my scripts had the `.sh' ending.  But I
-recently added some scripts without any extension, so `assert-shellcheck.sh`
-called for a second version.  The first attempt was to try grepping the shebang
-line:
-
-[source,sh]
-----
-$ grep '^#!/' assert-shellcheck.sh
-#!/usr/sh
-----
-
-Good, we have a grep pattern on the first try.  Let's try to find all the
-matching files:
-
-[source,sh]
-----
-$ find . -type f | xargs grep -l '^#!/'

-./scripts/ci-build.sh
-./scripts/generate-tasks-and-bugs.sh
-./scripts/songbooks.in
-./scripts/with-container.sh
-./scripts/assert-shellcheck.sh
-----
-
-This approach has a problem, though: it includes files ignored by Git, such as
-`builld-aux/install-sh~`, and even goes into the `.git/` directory and finds
-sample hooks in `.git/hooks/*`.
-
-To list the files that Git is tracking we'll try `git ls-files`:
-
-[source,sh]
-----
-$ git ls-files | xargs grep -l '^#!/'
-TODOs.org
-bootstrap
-build-aux/with-guile-env.in
-old/scripts/assert-docs-spelling.sh
-old/scripts/build-site.sh
-old/scripts/builder.bats.sh
-scripts/assert-shellcheck.sh
-scripts/assert-todos.sh
-scripts/ci-build.sh
-scripts/compile-readme.sh
-scripts/generate-tasks-and-bugs.sh
-scripts/songbooks.in
-scripts/with-container.sh
-----
-
-It looks to be almost there, but the `TODOs.org` entry shows a flaw in it: grep
-is looking for a +'^#!/'+ pattern on any part of the file.  In my case,
-`TODOs.org` had a snippet in the middle of the file where a line started with
-+#!/bin/sh+.
-
-So what we actually want is to match the *first* line against the pattern.  We
-could loop through each file, get the first line with `head -n 1` and grep
-against that, but this is starting to look messy.  I bet there is another way of
-doing it concisely...
-
-Let's try Awk.  I need a way to select the line numbers to replace `head -n 1`,
-and to stop processing the file if the pattern matches.  A quick search points
-me to using `FNR` for the former, and `{ nextline }` for the latter.  Let's try
-it:
-
-[source,sh]
-----
-$ git ls-files | xargs awk 'FNR>1 { nextfile } /^#!\// { print FILENAME; nextfile }'
-bootstrap
-build-aux/with-guile-env.in
-old/scripts/assert-docs-spelling.sh
-old/scripts/build-site.sh
-old/scripts/builder.bats.sh
-scripts/assert-shellcheck.sh
-scripts/assert-todos.sh
-scripts/ci-build.sh
-scripts/compile-readme.sh
-scripts/generate-tasks-and-bugs.sh
-scripts/songbooks.in
-scripts/with-container.sh
-----
-
-Great!  Only `TODOs.org` is missing, but the script is much better: instead of
-matching against any part of the file that may have a shebang-like line, we only
-look for the first.  Let's put it back into the `assert-shellcheck.sh` file and
-use `NULL` for separators to accommodate files with spaces in the name:
-
-[source,sh]
-----
-#!/usr/sh -eux
-
-git ls-files -z | \
-  xargs -0 awk 'FNR>1 { nextfile } /^#!\// { print FILENAME; nextfile }' | \
-  xargs shellcheck
-----
-
-This is where I've stopped, but I imagine a likely improvement: match against
-only +#!/bin/sh+ and +#!/usr/bin/env bash+ shebangs (the ones I use most), to
-avoid running ShellCheck on Perl files, or other shebangs.
-
-Also when reviewing the text of this article, I found that `{ nextfile }` is a
-GNU Awk extension.  It would be an improvement if `assert-shellcheck.sh` relied
-on the POSIX subset of Awk for working correctly.
-
-== _Update_
-
-After publishing, I could remove `{ nextfile }` and even make the script
-simpler:
-
-[source,sh]
-----
-#!/usr/sh -eux
-
-git ls-files -z | \
-  xargs -0 awk 'FNR==1 && /^#!\// { print FILENAME }' | \
-  xargs shellcheck
-----
-
-Now both the shell and Awk usage are POSIX compatible.

-I've wanted to change this website's favicon from a plain `.ico` file to a

-
-Generating a PNG from the existing 16x16 icon was possible but bad: the final
-image was blurry.  Converting the `.ico` to an SVG was possible, but
-sub-optimal: tools try to guess some vector paths, and the final SVG didn't
-match the original.

-Instead I used a tool to draw the "vector pixels" as black squares, and after

-The good thing about this new favicon (at {favicon}[`/static/lord-favicon.svg`])
-is that a) it is simple enough that I feel comfortable editing it manually and
-b) it is an SVG, which means I can generate any desired size.

-  <link rel="icon" type="image/svg+xml" href="/static/favicon.svg">

-Still missing is a bitmap image for places that can't handle vector images.  I
-used Jekyll generator to create an PNG from the existing SVG:
-

-module Jekyll
-  class FaviconGenerator < Generator
-    safe true

-        puts `inkscape -o #{png} -w #{SIZE} -h #{SIZE} #{svg}`
-      end
-    end
-  end
-end

-
-I had to increase the priority of the generator so that it would run before
-other places that would use a `{% link /static/lord-favicon.png %}`, otherwise
-the file would be considered missing.

-= Awk snippet: send email to multiple recipients with cURL
-
-:neomutt: https://neomutt.org/
-:found-out-article: https://blog.edmdesigner.com/send-email-from-linux-command-line/
-:curl: https://curl.se/
-
-As I experiment with {neomutt}[Neomutt], I wanted to keep being able to enqueue
-emails for sending later like my previous setup, so that I didn't rely on having
-an internet connection.
-
-My requirements for the `sendmail` command were:
-
-. store the email in a file, and send it later;
-. send from different addresses, using different SMTP servers.
-
-I couldn't find an MTA that could accomplish that, but I was able to quickly
-write a solution.
-
-The first part was the easiest: store the email in a file:
-
-[source,sh]
-----
-# ~/.config/mutt/muttrc:
-set sendmail=~/bin/enqueue-email.sh
-
-# ~/bin/enqueue-email.sh:
-#!/bin/sh -eu
-
-cat - > "$HOME/mbsync/my-queued-emails/$(date -Is)"
-----
-
-Now that I had the email file store locally, I needed a program to send the
-email from the file, so that I could create a cronjob like:
-
-[source,sh]
-----
-for f in ~/mbsync/my-queued-emails/*; do
-  ~/bin/dispatch-email.sh "$f" && rm "$f"
-done
-----
-
-The `dispatch-email.sh` would have to look at the `From:` header and decide
-which SMTP server to use.  As I {found-out-article}[found out] that {curl}[curl]
-supports SMTP and is able to send emails, this is what I ended up with:
-
-[source,sh]
-----
-#!/bin/sh -eu
-
-F="$1"
-
-rcpt="$(awk '
-  match($0, /^(To|Cc|Bcc): (.*)$/, m) {
-    split(m[2], tos, ",")
-    for (i in tos) {
-      print "--mail-rcpt " tos[i]
-    }
-  }
-'  "$F")"
-
-if grep -qE '^From: .*<addr@server1\.org>$' "$F"; then
-  curl                                                      \
-    -s                                                      \

-    --user 'addr@server2.org:my-long-and-secure-passphrase' \
-    --upload-file "$F"

-  echo 'Bad "From: " address'
-  exit 1

-
-Most of curl flags used are self-explanatory, except for `$rcpt`.
-
-curl connects to the SMTP server, but doesn't set the recipient address by
-looking at the message.  My solution was to generate the curl flags, store them
-in `$rcpt` and use it unquoted to leverage shell word splitting.
-
-To me, the most interesting part was building the `$rcpt` flags.  My first
-instinct was to try grep, but it couldn't print only matches in a regex.  As I
-started to turn towards sed, I envisioned needing something else to loop over
-the sed output, and I then moved to Awk.
-
-In the short Awk snippet, 3 things were new to me: the `match(...)`,
-`split(...)` and `for () {}`.  The only other function I have ever used was
-`gsub(...)`, but these new ones felt similar enough that I could almost guess
-their behaviour and arguments.  `match(...)` stores the matches of a regex on
-the given array positionally, and `split(...)` stores the chunks in the given
-array.
-
-I even did it incrementally:
-
-[source,sh]
-----
-$ H='To: to@example.com, to2@example.com\nCc: cc@example.com, cc2@example.com\nBcc: bcc@example.com,bcc2@example.com\n'
-$ printf "$H" | awk '/^To: .*$/ { print $0 }'
-To: to@example.com, to2@example.com
-$ printf "$H" | awk 'match($0, /^To: (.*)$/, m) { print m }'
-awk: ligne de commande:1: (FILENAME=- FNR=1) fatal : tentative d'utilisation du tableau « m » dans un contexte scalaire
-$ printf "$H" | awk 'match($0, /^To: (.*)$/, m) { print m[0] }'
-To: to@example.com, to2@example.com
-$ printf "$H" | awk 'match($0, /^To: (.*)$/, m) { print m[1] }'
-to@example.com, to2@example.com
-$ printf "$H" | awk 'match($0, /^To: (.*)$/, m) { split(m[1], tos, " "); print tos }'
-awk: ligne de commande:1: (FILENAME=- FNR=1) fatal : tentative d'utilisation du tableau « tos » dans un contexte scalaire
-$ printf "$H" | awk 'match($0, /^To: (.*)$/, m) { split(m[1], tos, " "); print tos[0] }'
-
-$ printf "$H" | awk 'match($0, /^To: (.*)$/, m) { split(m[1], tos, " "); print tos[1] }'
-to@example.com,
-$ printf "$H" | awk 'match($0, /^To: (.*)$/, m) { split(m[1], tos, " "); print tos[2] }'
-to2@example.com
-$ printf "$H" | awk 'match($0, /^To: (.*)$/, m) { split(m[1], tos, " "); print tos[3] }'
-----
-
-(This isn't the verbatim interactive session, but a cleaned version to make it
-more readable.)
-
-At this point, I realized I needed a for loop over the `tos` array, and I moved
-the Awk snippet into the `~/bin/dispatch-email.sh`.  I liked the final thing:
-
-[source,awk]
-----
-match($0, /^(To|Cc|Bcc): (.*)$/, m) {
-  split(m[2], tos, ",")
-  for (i in tos) {
-    print "--mail-rcpt " tos[i]
-  }
-}
-----
-
-As I learn more about Awk, I feel that it is too undervalued, as many people
-turn to Perl or other programming languages when Awk suffices.  The advantage is
-pretty clear: writing programs that run on any POSIX system, without extra
-dependencies required.
-
-Coding to the standards is underrated.

-= POSIX sh and shebangs
-
-:awk-1: link:../../../2020/12/15/shellcheck-repo.html
-:awk-2: link:../12/curl-awk-emails.html
-
-As I {awk-1}[keep moving] {awk-2}[towards POSIX], I'm on the process of
-migrating all my Bash scripts to POSIX sh.
-
-As I dropped `[[`, arrays and other Bashisms, I was left staring at the first
-line of every script, wondering what to do: what is the POSIX sh equivalent of
-`#!/usr/bin/env bash`?  I already knew that POSIX says nothing about shebangs,
-and that the portable way to call a POSIX sh script is `sh script.sh`, but
-I didn't know what to do with that first line.
-
-What I had previously was:
-
-[source,sh]
-----
-#!/usr/bin/env bash
-set -Eeuo pipefail
-cd "$(dirname "${BASH_SOURCE[0]}")"
-----
-
-Obviously, the `$BASH_SOURCE` would be gone, and I would have to adapt some of
-my scripts to not rely on the script location.  The `-E` and `-o pipefail`
-options were also gone, and would be replaced by nothing.
-
-I converted all of them to:
-
-[source,sh]
-----
-#!/bin/sh -eu
-----
-
-I moved the `-eu` options to the shebang line itself, striving for conciseness.
-But as I changed callers from `./script.sh` to `sh script.sh`, things started to
-fail.  Some tests that should fail reported errors, but didn't return 1.
-
-My first reaction was to revert back to `./script.sh`, but the POSIX bug I
-caught is a strong strain, and when I went back to it, I figured that the
-callers were missing some flags.  Specifically, `sh -eu script.sh`.
-
-Then it clicked: when running with `sh script.sh`, the shebang line with the sh
-options is ignored, as it is a comment!
-
-Which means that the shebang most friendly with POSIX is:
-
-[source,sh]
-----
-#!/bin/sh
-set -eu
-----
-
-. when running via `./script.sh`, if the system has an executable at `/bin/sh`,
-  it will be used to run the script;
-. when running via `sh script.sh`, the sh options aren't ignored as previously.
-
-TIL.

-= Common Lisp argument precedence order parameterization of a generic function

-multiple ones are available:
-
-[source,lisp]
-----

-
-#<STANDARD-CLASS CLASS-A {583E0B25}>

-; Compiling LAMBDA (.PV-CELL. .NEXT-METHOD-CALL. OBJ):
-; Compiling Top-Level Form:
-
-#<STANDARD-METHOD ANOTHER-FN (CLASS-B) {584B8895}>
-----
-
-Given the above definitions, when inheriting from `class-a` and `class-b`, the
-order of inheritance matters:
-
-[source,lisp]
-----
-* (defclass class-a-coming-first (class-a class-b) ())
-#<STANDARD-CLASS CLASS-A-COMING-FIRST {584BE6AD}>

-:CLASS-A
-
-* (another-fn (make-instance 'class-b-coming-first))
-:CLASS-B
-----
-
-Combining the order of inheritance with generic functions with multiple
-arguments, CLOS has to make a choice of how to pick a method given two competing
-definitions, and its default strategy is prioritizing from left to right:
-
-[source,lisp]
-----
-* (defgeneric yet-another-fn (obj1 obj2))
-#<STANDARD-GENERIC-FUNCTION YET-ANOTHER-FN (0) {584D9EC9}>

-
-* (yet-another-fn (make-instance 'class-a) (make-instance 'class-b))
-:FIRST-ARG-SPECIALIZED
-----
-
-CLOS has to make a choice between the first and the second definition of
-`yet-another-fn`, but its choice is just a heuristic.  What if we want the
-choice to be based on the second argument, instead of the first?
-
-For that, we use the `:argument-precedence-order` option when declaring a
-generic function:
-
-[source,lisp]
-----
-* (defgeneric yet-another-fn (obj1 obj2) (:argument-precedence-order obj2 obj1))
-#<STANDARD-GENERIC-FUNCTION YET-ANOTHER-FN (2) {584D9EC9}>
-
-* (yet-another-fn (make-instance 'class-a) (make-instance 'class-b))
-:SECOND-ARG-SPECIALIZED
-----
-
-I liked that the `:argument-precedence-order` option exists.  We shouldn't have
-to change the arguments from `(obj1 obj2)` to `(obj2 obj1)` just to make CLOS
-pick the method that we want.  We can configure its default behaviour if
-desired, and keep the order of arguments however it best fits the generic
-function.
-
-== Comparison with Clojure
-
-Clojure has an equivalent, when using `defmulti`.
-
-Since when declaring a multi-method with `defmulti` we must define the dispatch
-function, Clojure uses it to pick the method definition.  Since the dispatch
-function is required, there is no need for a default behaviour, such as
-left-to-right.
-
-== Conclusion
-
-Making the argument precedence order configurable for generic functions but not
-for class definitions makes a lot of sense.
-
-When declaring a class, we can choose the precedence order, and that is about
-it.  But when defining a generic function, the order of arguments is more
-important to the function semantics, and the argument precedence being
-left-to-right is just the default behaviour.
-
-One shouldn't change the order of arguments of a generic function for the sake
-of tailoring it to the CLOS priority ranking algorithm, but doing it for a class
-definition is just fine.
-
-TIL.

-This simplistic `defcurry` definition doesn't support optional parameters,
-multi-arity, `&` rest arguments, docstrings, etc., but it could certainly evolve
-to do so.
-
-I like how `defcurry` is so short, and abdicates the responsability of doing the
-multi-arity logic to Clojure's built-in multi-arity support.  Simple and
-elegant.
-
-Same Clojure as before, now with auto-currying via macros.
-
-== Comparison with Common Lisp
-
-My attempt at writing an equivalent for Common Lisp gives me:
-
-[source,lisp]
-----
-(defun partial (fn &rest args)
-  (lambda (&rest args2)
-    (apply fn (append args args2))))
-
-(defun curry-n (n func)
-  (cond ((< n 0) (error "Too many arguments"))
-        ((zerop n) (funcall func))
-        (t (lambda (&rest rest)
-             (curry-n (- n (length rest))
-                      (apply #'partial func rest))))))
-
-(defmacro defcurry (name args &body body)
-  `(defun ,name (&rest rest)
-     (let ((func (lambda ,args ,@body)))
-       (curry-n (- ,(length args) (length rest))
-                (apply #'partial func rest)))))
-----
-
-Without built-in multi-arity support, we have to do more work, like tracking the
-number of arguments consumed so far.  We also have to write `#'partial`
-ourselves.  That is, without dependending on any library, sticking to ANSI
-Common Lisp.
-
-The usage is pretty similar:
-
-[source,lisp]
-----
-* (defcurry add (a b c d e)
-    (+ a b c d e))
-ADD
-
-* (add 1)
-#<FUNCTION (LAMBDA (&REST REST) :IN CURRY-N) {100216419B}>
-
-* (funcall (add 1) 2 3 4)
-#<FUNCTION (LAMBDA (&REST REST) :IN CURRY-N) {100216537B}>
-
-* (funcall (add 1) 2 3 4 5)
-15
-
-* (funcall (funcall (add 1) 2 3) 4 5)
-15
-
-* (macroexpand-1
-    '(defcurry add (a b c d e)
-       (+ a b c d e)))
-(DEFUN ADD (&REST REST)
-  (LET ((FUNC (LAMBDA (A B C D E) (+ A B C D E))))
-    (CURRY-N (- 5 (LENGTH REST)) (APPLY #'PARTIAL FUNC REST))))
-T
-----
-
-This also require `funcall`s, since we return a `lambda` that doesn't live in
-the function namespace.
-
-Like the Clojure one, it doesn't support optional parameters, `&rest` rest
-arguments, docstrings, etc., but it also could evolve to do so.

-= Three-way conditional for number signs on Lisp

-A useful macro from Paul Graham's {on-lisp}[On Lisp] book:
-
-[source,lisp]
-----
-(defmacro nif (expr pos zero neg)
-  (let ((g (gensym)))
-    `(let ((,g ,expr))
-       (cond ((plusp ,g) ,pos)
-             ((zerop ,g) ,zero)
-             (t ,neg)))))
-----
-
-After I looked at this macro, I started seeing opportunities to using it in many
-places, and yet I didn't see anyone else using it.
-
-The latest example I can think of is section 1.3.3 of {sicp}[Structure and
-Interpretation of Computer Programs], which I was reading recently:
-
-[source,scheme]
-----
-(define (search f neg-point pos-point)
-  (let ((midpoint (average neg-point pos-point)))
-    (if (close-enough? neg-point post-point)
-        midpoint
-        (let ((test-value (f midpoint)))
-          (cond ((positive? test-value)
-                 (search f neg-point midpoint))
-                ((negative? test-value)
-                 (search f midpoint pos-point))
-                (else midpoint))))))
-----
-
-Not that the book should introduce such macro this early, but I couldn't avoid
-feeling bothered by not using the `nif` macro, which could even remove the need
-for the intermediate `test-value` variable:
-
-[source,scheme]
-----
-(define (search f neg-point pos-point)
-  (let ((midpoint (average neg-point pos-point)))
-    (if (close-enough? neg-point post-point)
-        midpoint
-        (nif (f midpoint)
-             (search f neg-point midpoint)
-             (midpoint)
-             (search f midpoint pos-point)))))
-----
-
-It also avoids `cond`'s extra clunky parentheses for grouping, which is
-unnecessary but built-in.
-
-As a macro, I personally feel it tilts the balance towards expressivenes despite
-its extra cognitive load toll.

-On the first line we import the public key (funnily enough, available via
-HTTPS), and after cloning the code via the insecure `git://` protocol, we use
-`git verify-commit` to check the signature.
-
-The verification is successful, and we can see that the public key from the
-signature matches the fingerprint of the imported one.  However
-`git verify-commit` doesn't have an option to check which public key you want to
-verify the commit against.  Which means that if a MITM attack happens, the
-attacker could very easily serve a malicious repository with signed commits, and
-you'd have to verify the public key by yourself.  That would need to happen for
-subsequent fetches, too.
-
-Even though this is possible, it is not very convenient, and certainly very
-brittle.  Despite the fact that the Git Protocol is much faster, it being harder
-to make secure is a big downside.

-= Encoding and decoding JavaScript BigInt values with reviver
-:updatedat: 2021-08-13
-
-:reviver-fn: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse#using_the_reviver_parameter
-:bigint: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/BigInt
-:json-rfc: https://datatracker.ietf.org/doc/html/rfc8259
-
-`JSON.parse()` accepts a second parameter: a {reviver-fn}[`reviver()` function].
-It is a function that can be used to transform the `JSON` values as they're
-being parsed.
-
-As it turns out, when combined with JavaScript's {bigint}[`BigInt`] type, you
-can parse and encode JavaScript `BigInt` numbers via JSON:
-
-[source,javascript]
-----
-const bigIntReviver = (_, value) =>
-    typeof value === "string" && value.match(/^-?[0-9]+n$/)
-        ? BigInt(value.slice(0, value.length - 1))
-        : value;
-----
-
-I chose to interpret strings that contains only numbers and an ending `n`
-suffix as `BigInt` values, similar to how JavaScript interprets `123` (a number)
-differently from `123n` (a `bigint`);
-
-We do those checks before constructing the `BigInt` to avoid throwing needless
-exceptions and catching them on the parsing function, as this could easily
-become a bottleneck when parsing large JSON values.
-
-In order to do the full roundtrip, we now only need the `toJSON()` counterpart:
-
-[source,javascript]
-----
-BigInt.prototype.toJSON = function() {
-    return this.toString() + "n";
-};
-----
-
-With both `bigIntReviver` and `toJSON` defined, we can now successfully parse
-and encode JavaScript objects with `BigInt` values transparently:
-
-[source,javascript]
-----
-const s = `[
-    null,
-    true,
-    false,
-    -1,
-    3.14,
-    "a string",
-    { "a-number": "-123" },
-    { "a-bigint": "-123n" }
-]`;
-
-const parsed = JSON.parse(s, bigIntReviver);
-const s2 = JSON.stringify(parsed);
-
-console.log(parsed);
-console.log(s2);
-
-console.log(typeof parsed[6]["a-number"])
-console.log(typeof parsed[7]["a-bigint"])
-----
-
-The output of the above is:
-
-[source,javascript]
-----
-[
-  null,
-  true,
-  false,
-  -1,
-  3.14,
-  'a string',
-  { 'a-number': '-123' },
-  { 'a-bigint': -123n }
-]
-[null,true,false,-1,3.14,"a string",{"a-number":"-123"},{"a-bigint":"-123n"}]
-string
-bigint
-----
-
-If you're on a web browser, you can probably try copying and pasting the above
-code on the console right now, as is.
-
-Even though {json-rfc}[`JSON`] doesn't include `BigInt` number, encoding and
-decoding them as strings is quite trivial on JavaScript.
