Someone has started to run git pull on one of my repos – once every two minutes. This is a very pointless endeavour. I push new code a couple of times per month.
So far, this isn’t causing any issues. I think this is just a regular human being who misconfigured some automation. And I hope this doesn’t mean that the “AI” bots have finally discovered my page …

Finally I propose that we increase the Twt Hash length from
⤋ Read More
7 to 12 and use the first 12 characters of the base32 encoded blake2b hash. This will solve two problems, the fact that all hashes today either end in q or a (oops) 😅 And increasing the Twt Hash size will ensure that we never run into the chance of collision for ions to come. Chances of a 50% collision with 64 bits / 12 characters is roughly ~12.44B Twts. That ought to be enough! -- I also propose that we modify all our clients and make this change from the 1st July 2025, which will be Yarn.social's 5th birthday and 5 years since I started this whole project and endeavour! 😱 #Twtxt #Update
I will be adding the code in for yarnd very soon™ for this change, with a if the date is >= 2025-07-01 then compute_new_hashes else compute_old_hashes

@bender@twtxt.net Hehe good sleuthing 🤣 I swear it was an edit ✍️ Haha 😂 yarnd now “sees” both every single time, where-as before it would just obliterate the old Twt, but remain in archive. Now you get to see both 😅 Not sure if that’s a good thing or not, but it certainly makes it much clearer how to write “code logic” for detecting edits and doing something more UX(y) about ‘em 🤔

To the parents or teachers: How do you teach kids to program these days? 🤔
⤋ Read More
@movq@www.uninformativ.de I started with Delphi in school, the book (that we never ever used even once and I also never looked at) taught Pascal. The UI part felt easy at first but prevented me from understanding fundamental stuff like procedures or functions or even begin and end blocks for ifs or loops. For example I always thought that I needed to have a button somewhere, even if hidden. That gave me a handler procedure where I could put code and somehow call it. Two or three years later, a new mate from the parallel class finally told me that this wasn’t necessary and how to do thing better.
You know all too well that back in the day there was not a whole lot of information out there. And the bits that did exist were well hidden. At least from me. Eventually discovering planet-quellcodes.de (I don’t remember if that was the original forum or if that got split off from some other board) via my best schoolmate was like finding the Amber Room. Yeah, reading the ITG book would have been a very good idea for sure. :-)
In hindsight, a console program without the UI overhead might have been better. At least for the very start. Much less things to worry about or get lost.
Hence, I’d recommend to start programming with a console program. As for the language, not sure. But Python is probably a good choice, it doesn’t require a lot of surrounding boilerplate like, say Java or Go. It also does exceptionally well in the principle of least surprise.
I just fixed a bug in tt’s reply to parent feature. Previously, when the message tree looked like the following
Message
├╴Reply 1
│ └╴Subreply
└╴Reply 2
and “Reply 2” was selected, pressing A to reply to the parent should have picked “Message”. However, a reply to “Reply 2” was composed instead. The reason was a precausiously introduced safety guard to abort the parent search which stopped at “Subreply”, because its subject didn’t match “Reply 2”’s. It was originally intended to abort on a completely different message conversation root. Just in case. Turns out that this thoght was flawed.
Fixing bugs by only removing code is always cool. :-)

@movq@www.uninformativ.de @aelaraji@aelaraji.com Yes @david@collantes.us It would be good for me, or new developers, if the documentation were agnostic. And if possible with many example cases. I’m fine-tuning the code as you inform me of bugs, trial and error. It’s a lesson to be learned for the future.

“That PHP snippet could be merged into https://twtxt.dev/exts/twt-hash.html”
Why, though?

AI problems, top to bottom:
1: Open AI nerds, believe fine tuning a language model algorithm, will eventually produce an AGI god.
2: Subpar artists and techbros who can’t code, convinced AI image bashing and vibe coding, will help convince the dumber parts of Internet, they are a real deal.
3: Parasites, using AI to scam people, because they just want passive income, selling crap, made by an automated process.
Side: Adobe&co, killing Flash/old web, pricing new artists and developers out, to face learning curves of free tools, or use AI, peddled as solution.
