1. Install mkvtoolsnix.
2. brew install --with-qt5 mkvtoolnix
3. Use mkvinfo to get the audio track IDs that you want.
4. mkvinfo *.mkv
5. Note that the audio track IDs are not the track numbers. Check the man page of mkvmerge or mkvinfo for more details.
6. Use mkvmerge to create a copy of the mkv with ONLY the desired tracks using --audio-tracks.
7. mkvmerge -o out.mkv -a 2 orig.mkv

exFAT support on macOS seems to have some bugs because my external drives with exFAT formatting will randomly get corrupted.

Disk Utility is unable to repair this at first, but the fix is this:

1. Use diskutil list to find the right drive id.
2. You want the id under the IDENTIFIER column, it should look like disk1s1
3. Run sudo fsck_exfat -d <id from above>. eg sudo fsck_exfat -d disk1s3
4. -d is debug so you'll see all your files output as they're processed.
5. Answer YES if it gives you the prompt Main boot region needs to be updated. Yes/No?

Port forwarding should be fairly straightforward, but what Arris doesn't tell you is that you need to have the firewall on in order for port forwarding settings to have an effect.

I don't know why the "firewall off" option would mean "block everything", but as best I can tell, that was the case on my Arris DG2470A (from RCN, could be some custom firmware that RCN uses?)

So step by step:

I always forget these steps and have to google for them, even though they're super simple

Prereq:

• pip install gsutil
• gsutil config, have your project id ready.

1. tar --create --verbose --xz --file images.tar.xz /directory/containing/images/*
2. gsutil cp images.tar.xz gs://<bucket name>

zpty

Zsh has a feature called zpty which creates a pseudo-terminal in the background.

According to the docs, this can be useful to run a program in the background that expects to be run in a normal terminal environment.

Some zsh themes such as pure use this to run commands asynchronously. Pure uses the zsh plugin zsh-async for this.

DirectTV Now added a FreeVIEW thing where you can watch some tv shows for free, but they don't show you only the shows that are available on "FreeVIEW", because that would be too convenient.

Luckily, they helpfully mark these subscriber only shows with a badge on the /watch/shows endpoint.

Here's a bookmarklet to hide the subscriber only shows.

javascript:document.querySelectorAll("[data-label='SUBSCRIBE']").forEach( (el) => { el.parentNode.parentNode.parentNode.parentNode.style.display = 'none'; });
