Take this with a grain, micro-dose or truck of salt, but I wanted to do some mask math.
One stubborn confusion I often see, and tried to clarify at the bottom, is the difference between effectiveness (how many times a mask prevents spread) and filter quality (what percentage of particles it stops). A low quality mask can be very effective in some settings!

Didn't see this coming: another 25% speedup in signature validation on Bitcoin. No consensus changes, everything already implemented and tested. Only a patent was in the way, and it just expired. https://twitter.com/pwuille/status/1309707188575694849
The new setup is based on this 5 year old blog post. Although Zoom (slighty?) updated their H6 it's nice to see not much changed.
Plug analog mics into the little device, turn of phones to prevent interference, adjust volume (I need more practice with that), press record, press stop, put SD card in laptop and mail WAV files (1 per mic) to editor. 3 meter extension cables even make it corona-proof :-)

We also switched from USB mics to analog gear. It's an absolute pain in the ass to get multiple USB mics to behave, especially when there's three, as in episode 8 with Ruben Somsen about state chains. macOS just magically combines them in a single surround sound track, leaving your audio editor confused. No way to adjust volume. Monitoring also adds a slight delay, making you feel you're a robot. It's easy to mess up settings and fail to record and annoying to export in useful format. So...

Disturbing reports that Google Play is threatening to kick out Mastodon apps. See:

App stores have a track record of acting capriciously & are also easy targets for gov't censors (including Trump). This is why alternatives like @fdroidorg are so important for user freedom.
If unfamiliar: F-Droid is a free & open source app you can use to install other Android apps, with focus on free & open source software. Get it here:
Back from holidays! In episode 6 @AaronvanW explain various ways to share a single UTXO amongst multiple people. We start with a simple multisig address and work our way up to payment pools:

A new c-lightning release has been tagged (with another hilarious name). You can now send payments through multiple channels at once, increasing both privacy and routing pathways for your transactions of larger amounts.

Someone in Utrecht threw a birthday party at a bar and later found out he had Corona. At least 16 infected, including other guests. Poor guy.

RT @matt_odell
Spent the morning building this out with @DennisReimann.
Introducing http://bitcoindevlist.com.
If you are working on a bitcoin project and currently accepting donations: submit a PR and get yourself added.
If you are a bitcoiner: please consider supporting our builders!
@AaronvanW addendum: it looks like the 1 MB limit did have an activation flag height. There's actually 3 commits:
1. introduce the limit: https://github.com/bitcoin/bitcoin/commit/a30b56ebe76ffff9f9cc8a6667186179413c6349
2. set a flag height: https://github.com/bitcoin/bitcoin/commit/f1e1fb4bdef878c8fc1564fa418d44e7541a7e83#diff-118fcbaaba162ba17933c7893247df3aR1421
3. remove the flag height (presumably once it was active): https://github.com/bitcoin/bitcoin/commit/172f006020965ae8763a0610845c051ed1e3b522
The changes are buried deep inside innocuously named commits. Don't get lazy with code review...
