TODO Send patch to upstream `bmake` for bug on `$*` macro {#td-ca621da2-2e94-ae6f-0e3d-db744c00a656}

TODO in 2021-11-21

From the standard:

$*      The $* macro shall evaluate to the current target name with its suf‐
        fix deleted. It shall be evaluated at least for inference rules.

        For example, in the .c.a inference rule, $*.o represents the out-of-
        date .o file that corresponds to the prerequisite .c file.

Given the Makefile:

.POSIX:

.SUFFIXES: .x .y

.x.y:
        cp $< $*.y

all: a/b.y

bmake works correctly without flags, but behaves incorrectly with -j1:

$ mkdir a && touch a/b.x
$ make -j1
cp a/b.x b.y
$ make
cp a/b.x a/b.y

This impacts the upcoming lilypond -o $name command in the Makefile.

DONE in 2020-12-28

Done when moved to WebM. Firefox gives an error when loading the file directly, and a different error when loading with WebTorrent. I'll call this a Firefox error, since Chromium was able to play the video on both, since both the file creation and serving are pretty straighforward.

When loading the file directly, Firefox says with console.warn():

Media resource https://euandre.org/screencast/2020/12/24/sample-screencast.webm could not be decoded, error: Error Code: NS_ERROR_DOM_MEDIA_DECODE_ERR (0x806e0004) Details: virtual mozilla::MediaResult mozilla::FFmpegVideoDecoder<46465650>::DoDecode(mozilla::MediaRawData*, uint8_t*, int, bool*, mozilla::MediaDataDecoder::DecodedData&): avcodec_send_packet error: -1

When loading with WebTorrent, Firefox says with console.error():

Future-proof wesite (and also later software): - remove Jekyll - remove markdown, or embed markdown process, and write in HTML directly (and maybe commit the HTML) - commit directly most derived data, such as torrent files, ogg media, SVG from graphviz input, etc., so that the absence of those tools don't impede the generation of existing pages of the website. Move brinquedoteca out of jekyll?

FIXMEs: - DIY: - CommonMark parser - envsubst, with errors on undefined variables - date -d isn't POSIX: simple replacement - translation not coming from english (like pt -> fr) - add linkchecker - how to use tmp fd over tmpfile? - po4a for markdown... - render slides - shrink CSS - build makemake output in parallel - remove the need for makemake: it is the slowest step, and sometimes breaks the Makefile graph
