New release of Joinmarket.
(REDRAFT: Small bug in 0.6.3 fixed so replacing with

Improvements and bugfixes as usual make upgrading recommended. Most notable is that next release will deprecate Py3.5 and earlier, read here for details:


Also a binary (static build) for Linux 64 bit that you can try is attached to the release. Verify signatures as usual please :)

Apparently btcpayserver is starting to randomize wallet fingerprints for improved privacy. This is pretty cool.


(I think there are more things they're randomizing but not sure of details).

So BIP78 has been merged (no, don't ask me what that means!) and even has a test vector:


It's interesting how much debate there was about tiny subtleties of fee choice and restriction, and what each side checks - even the most trivial 2 party protocol can be hugely complex with interactivity.

We focus so much on staying safe and not risking anything. What is the point of a life if you're too afraid to do anything interesting with it?

So, some people still believe that banning Gab from fedi somehow helps with fighting fascism. You (I assume very young) people should consider:

1. Not listening to someone doesn't mean that they magically disappear from planet Earth
2. Not being able to see your opponent means you're robbing yourself of the ability to understand them, and thus defend against them (or even understand where they're coming from and address their concerns in civil argument)

I've used 'make' quite a lot, but never really understood it.
pkgw.github.io/make_for_scient has been great for making me understand it better.

"some recipes are a lot more complicated than that, and it's important to have them stored somewhere other than your shell history"

This struck a chord with me.
I rely on my shell history WAY too much.
I've done quite a bit of experimentation with video conversion and am now documenting it in markdown file(s)

What do you do to not rely on your shell history?

Interesting aspects of the Wirecard case: short selling was banned at one point. Journalists investigating were threatened ("McCrum pursued Wirecard despite becoming the target of a BaFin investigation into stock manipulation..").
The short selling/derivatives thing is a hobby horse of mine: it's incredible to me how few people get that shorting and derivatives can *only* improve the quality of markets. Shorting roots out fraud. This is a very concrete and obvious case.


In doing open source documentation (like release notes and similar) collaboration, I've noticed something interesting: many people will perceive as typos things that I learned as correct formal English decades ago. It's definitely partly about native vs non-native speakers (FOSS is global), but I think it's also that language shifted substantially in the new internet age, and some grammatical constructions considered correct (for formal writing) in, say, the 1980s are now perceived as errors.

It's about time we stopped buying into the propaganda phrase "ad blockers", and started calling user-protection tools like #uBlockOrigin and #NoScript what they are; spy blockers. If I display ads on my website using HTML and CSS, spy blockers won't block those. As far as they know, the text, images, audio, or video that make up the ads could be anything. So what's really being blocked is not ads, but tracking. Thanks to the authors of this site, for pointing this out:
