In episode 14 @AaronvanW and I explain Assume-UTXO, as well as some earlier performance improvements like headers-first and assumevalid.

@emil @momar I don't get why EFF is "disappointed" by the RIAA. It's like being disappointed by Philip Morris still trying to get children addicted to smoking in countries where they get away with it.

The good news is that although Github is centralized, git repositories themselves are not. So it's probably fine to use Github as long as it works. Don't jump off a ship before it sinks, even if you're a good swimmer :-)

In episode 11 @AaronvanW and I discuss the Easypaysy proposal, a bit of BIP 47 Payment Codes and if you really want to use the blockchain for your address book.

Bitcoin Optech newsletter #117 is here:

- describes a compiler bug that casts doubt on the safety of secure systems
- explains a technique that can be used to more efficiently verify ECDSA signatures in Bitcoin
- popular Q&A from the Bitcoin StackExchange

@frank87 zodat naast de Belastingdienst ook het OM je inkomen weet? Lijkt me niet ideaal. Ik zou eerder de Amerikaanse aanpak kiezen (minus de discriminatie) om overtreders veel laagdrempeliger voor de rechter te laten verschijnen. Dat raakt veelverdieners mogelijk ook vrij hard, wegen tijdsverlies en reputatieschade.

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.

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:

@jon @waxwing I've been very lazy moving my Medium over to Wordpress one by one, but it will happen...

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:

This guy's videos are really funny.

The bit at the end about return to nature in particular had me cracking up 😂
