## TODO Send patch to upstream `bmake` for bug on `$*` macro {#td-ca621da2-2e94-ae6f-0e3d-db744c00a656}
- TODO in 2021-11-21

---

From the standard:

```txt
$*      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:

```makefile
.POSIX:

.SUFFIXES: .x .y

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

all: a/b.y
```

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

```shell
$ 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 Fix play of videos with WebTorrent {#task-9d75fe3a-b7e5-4cc5-9300-1054c7e981c0}
- 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)

  ```

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

  ```
  Uncaught Error: XDR encoding failure
  ```
