Day 7 was pretty tough, I initially ended up implementing an exponential in both time and memory solution that I killed because it was eating all the resources on my Mac Studio, and this poor little machine only has 32GB of memory (I stopped it at 118GB of memory, swapping badly!), This is what I ended up doing before/after:

• Before: Time O(2^k · L), memory O(2^k), where k is the number of splitters along a reachable path and L is path length. Exponential in k.
  
• After: Time O(R·C) (or O(R·C + s) with s split events), memory O©, where R = rows, C = columns. Polynomial/linear in grid size.

I’m seeing crashes in the 3D subsystem. (Gallium? Glamor? Whatever other Mesa thing they have? No idea.) In the logs I find this:

malloc(): unaligned tcache chunk detected

And that’s why I still care about Rust and want to learn more about it, even though it’s giving me so much headache and I’ve given up so many times. Because Rust currently seems to be the only popular systems programming language that tries to eliminate these error classes.

And of course “the Rust experiment” in the Linux kernel has recently been concluded as “successful”, so that alone is reason enough for me:

Alright, Advent of Code is over:

It’s been quite the time sink, especially with the DOS games on top, but it was fun. 🥳

In case you’re wondering: All puzzles (except for part 2 of day 10) were doable in Python 1 on SuSE Linux 6.4 and ran in a finite time on the Pentium 133. Puzzle 10/2 might have been doable as well if I had better education. 🤣

@shinyoukai@neko.laidback.moe Time to become a trixie or forky!

Webp, though it has been around for a long while, wasn’t fully supported on all browsers until recently. The other formats have been in use for such a long time, proving to work just fine, that the advantages Webp provides haven’t been seemingly enough to merit a switch.

Google is also the one behind Webp, and, well, people don’t trust, nor like, them much.

@movq@www.uninformativ.de @zvava@twtxt.net I think people get sick of everything changing all the time and so don’t bother adopting things to change when things are already good enough 🤷

@bender@twtxt.net on the way o7  spent enough time away from the codebase

Fuck me, soooooooo beautiful! Awwww! :‘-) https://www.youtube.com/watch?v=oYfKgi133qo

This focuses more on the landscape part, other episodes also have amazing interactions with the locals. I cannot recommend the Itchy Boots channel enough. It’s in my top three channels of all time I believe. I hardly get the travel bug, but this has now changed. Watching Noraly’s videos brings me great joy. It also shows humanity is not lost, contrary to what one might think in this crazy world. :-)

Caution, this channel gets very addictive!

@prologic@twtxt.net Bwahahaha! I tried to establish some form of “convention” for commit messages at work (not exactly what you linked to, though), but it’s a lost cause. 😂 Nobody is following any of that. Nobody wants to invest time in good commit messages. People just want to get stuff done.

I’m just glad that 80% are at least somewhat useful – instead of “wip” or “shit i screwed up”.

@lyse@lyse.isobeef.org no wonder I picked that cake (albeit coincidentally), I adore almonds, and hazelnuts! Your teammates are absolutely amazing, dude! A very nice project farewell! On leaving places I have a small anecdote.

I know someone who on 3 February 2004 left his job to go elsewhere. At the time his teammates threw a party, and gave him a very nice portable storage. Twenty days later, he returned, and jokingly they asked him for the storage, and money spent on farewell party back. I heard, from a close source, that he gave them his middle finger, but don’t quote me on that. 😂😂😂

@kiwu@twtxt.net I’ve no idea about regulations in your area, but over here there are different taxation rules for video and photo cameras. Hence, manufacturers limit the video recording time of photo cameras typically to half an hour, so that they don’t classify as video cameras with their higher taxes.

@prologic@twtxt.net Tada! There you once hope for your flight and ride to be delayed and then of course they are right on time! :-D You gotta wait either way. ;-) Looks like you got some good drinks, though.

@lyse@lyse.isobeef.org I want to record vlogs. it doesn’t have to be a super high quality one, just something that records for longer periods of time!!

@bender@twtxt.net a mobile phone camera doesn’t cut it because it cant take long videos. I would say like the cheapest possible tbh! it doesn’t have to be an amazing grade a camera, just something that will record in decent quality for long periods of time! I mostly want it to make vlogs :p

@aelaraji@aelaraji.com Thanks for the account! I figured out one thing at least so far, my WAF was blocking some of the AP requests. Fixed that. Anyway, holiday time 🤣 Back in ~2 weeks.

The funny thing is, Yarn moving to Twt Hash v2 sounds a tad more optimistic than Git adopting SHA-256.

Git is several years too late, while Yarn is pretty much on time.

@aelaraji@aelaraji.com Ahhh! That would be even funnier and even more brilliant! 🤣 If you can find this, I would happily employ this tactic next time and make ‘em pay 💰 Bahahahaha 🤣

@prologic@twtxt.net it would have been so much easy to run your own. I guess we all like to suffer every once and then, and this time is your turn. 😅

Fark me again with the bots. This time DDoS-style crawling from hundreds of IPs and dozens of ASN(s) wtf?!
I’ve had to disale the Ingress to my Git instance for the time being, i need to sleep and I can’t fight this :/

yakumo.dev is finally done for, November 26, 2025 in UTC time.

So long… I won’t be missing it though

@movq@www.uninformativ.de Seems fine to me! Plenty of time to get our shit™ in order! 🙌

@prologic@twtxt.net Time to make a new internet. Maybe one that intentionally doesn’t “scale” and remains slow (on both ends) so it’s harder to overload in this manner, harder to abuse for tracking your every move, … Got any of those 56k modems left?

(I’m half-joking. “Make The Internet Expensive Again” like it was in the 1990ies and some of these problems might go away. Disclaimer: I didn’t have my coffee yet. 😅)

Fark me 🤦‍♂️ I woke up quite late today (after a long night helping/assisting with a Mainframe migration last night fork work) to abusive traffic and my alerts going off. The impact? My pod (twtxt.net) was being hammered by something at a request rate of 30 req/s (there are global rate limits in place, but still…). The culprit? Turned out to be a particular IP 43.134.51.191 and after looking into who own s that IP I discovered it was yet-another-bad-customer-or-whatever from Tencent, so that entire network (ASN) is now blocked from my Edge:

+# Who: Tentcent
+# Why: Bad Bots
+132203

Total damage?

$ caddy-log-formatter twtxt.net.log | cut -f 1 -d  ' ' | sort | uniq -c | sort -r -n -k 1 | head -n 5

      8 106.200.1.116
      6 104.250.53.138

61k reqs over an hour or so (before I noticed), bunch of CPU time burned, and useless waste of my fucking time.

All my newly added test cases failed, that movq thankfully provided in https://git.mills.io/yarnsocial/twtxt.dev/pulls/28#issuecomment-20801 for the draft of the twt hash v2 extension. The first error was easy to see in the diff. The hashes were way too long. You’ve already guessed it, I had cut the hash from the twelfth character towards the end instead of taking the first twelve characters: hash[12:] instead of hash[:12].

After fixing this rookie mistake, the tests still all failed. Hmmm. Did I still cut the wrong twelve characters? :-? I even checked the Go reference implementation in the document itself. But it read basically the same as mine. Strange, what the heck is going on here?

Turns out that my vim replacements to transform the Python code into Go code butchered all the URLs. ;-) The order of operations matters. I first replaced the equals with colons for the subtest struct fields and then wanted to transform the RFC 3339 timestamp strings to time.Date(…) calls. So, I replaced the colons in the time with commas and spaces. Hence, my URLs then also all read https, //example.com/twtxt.txt.

But that was it. All test green. \o/

@lyse@lyse.isobeef.org @bender@twtxt.net Pfft, they want folks to relocate to Sydney. Fuck that 🤣 Sydney is a bit like San Francisco, I’m not actually sure which is worse. Fuck’n expensive as hell, the only palce you’d be able to afford to buy or rent is at least ~2hrs out of the city by public transport (i.e: train) and by that time you’ve just pissed your life down the toilet, because you’d be expected ot work a 9-10hr day + 2-3hrs of travel each way, buy the time you factor in having to wake up super early to get ready to travel in to work, you basically have zero time for anything else, let alone your ufamily,

Fuck that.

@prologic@twtxt.net I couldn’t have phrased it any better than @bender@twtxt.net. :-)

Twice or three times the money as before sounds a bit suspicious to me. Of course, I could be wrong, but I always was under the impression, that your last jobs weren’t all that badly salaried. If the new offer is really paid this highly, it might be a shit job. For me, money isn’t everything, I’d rather opt for a lower income where the job is fun than hating to go to work every day. But if the new job ticks all boxes, go for it. :-)

Also: Consult your pillow, don’t rush it.

I had no meetings this arvo, so I made an appointment with the woods in my extended lunch break. The 6°C warm sun was out all day long and there was only a very light breeze. So, a very nice autumn day.

When I stopped to take a photo in the forest, a deer behind me took off into the woodland. I didn’t see it before. Also, I came across one or the other clearing. Sadly, it’s all commercial timberland here. Luckily, in a year or so, when nature slowly took over and reclaimed some spots, the apocalyptic sites are then looking a bit more decent again.

Cleaning of the ruin walls on my backyard mountain slowly takes shape. They made some progress and moved on to the other section. The flag on top is halfway disintegrated again, all the yellow half is completely gone. I’m wondering if they just stop replacing it at some point in time. But probably not.

Enjoy! https://lyse.isobeef.org/waldspaziergang-2025-11-19/

@lyse@lyse.isobeef.org @bender@twtxt.net that’s also what Yarn.social’s logo is, and just happens to be the yarnd default. Hmmm figured times for a change? 🤔

I know its been a long time, but I did come about around to howl a bit recently https://git.gay/xjix/howl needs a ton of work to be usable, but I think itll be a fun way to browse the twtxtverse.

@movq@www.uninformativ.de I think I now remember having similar problems back then. I’m pretty sure I typically consulted the Qt C++ documentation and only very rarely looked at the Python one. It was easy enough to translate the C++ code to Python.

Yeah, the GIL can be problematic at times. I’m glad it wasn’t an issue for my application.

@prologic@twtxt.net Hm, same startup delay. (Go is not an option for me anyway.)

It’s hard to tell why all this is so slow. Maybe in this particular case it has something to do with fonts: strace shows the program loading the fontconfig configs several times, and that takes up a bulk of the startup time. 🤔 (Qt6 or Java don’t do that, but they’re still slow to start up – for other reasons, apparently.)

To be fair, it’s “just” the initial program startup (with warm I/O caches). Once it’s running, it’s fine. All toolkits I’ve tried are. But I don’t want to accept such delays, not in the year 2025. 😅 Imagine every terminal window needing half a second to appear on the screen … nah, man.

I like to read through old RPG books and zines for inspiration for my games, and lately I’ve been enjoying the Arduin Grimoire (https://en.wikipedia.org/wiki/Arduin), one of the earliest 3rd-party zines (coming out during the initial run of OD&D). It’s filled with a bunch of unique ideas (some better than others), entirely too many charts, and is very much a product of its time, but there’s something about its “raw”-ness (and its variety) that I still find appealing.

Be it Java with Swing or PyQt6, it takes ~300 ms until a basic window with a treeview and a listbox appears. That is a very noticeable delay.

Is it unrealistic to expect faster startup times these days? 🤔

Once the program is running, a new second window (in the same process) appears very quickly. So it’s all just the initialization stuff that takes so long. I could, of course, do what “fat” programs have done for ages: Pre-launch the process during boot, windowless. But I was hoping that this wasn’t needed. 😞 (And it’s a bad model anyway. When the main process crashes, all windows crash with it.)

Man, @quark@ferengi.one has an absolute gold mine. Having dealt again with different clocks and all sorts of strange time things at work today, this made my day! https://netbros.com/1755172401/ :‘-D

@bender@twtxt.net Twtxt <-> ActivityPub (2nd time’s the charm? 🤣)

This looks like a botnet, to be honest. The IPs are all over the place. Ethopia, Brazil, Kenya, Lebanon, Netherlands, … I mean, that’s the logical thing to do, isn’t it? Do your web crawling on infected PCs. Nobody will block those, because those are the same IP ranges as legitimate requests. And obviously you don’t have to pay for computing time.

… and they all send invalid HTTP requests, all answered with HTTP 400 … How silly.

I used Gemini (the Google AI) twice at work today, asking about Google Workspace configuration and Google Cloud CLI usage (because we use those a lot). You’d think that it’d be well-suited for those topics. It answered very confidently, yet completely wrong. Just wrong. Made-up CLI arguments, whatever. It took me a while to notice, though, because it’s so convincing and, well, you implicitly and subconsciously trust the results of the Google AI when asking about Google topics, don’t you?

Will it get better over time? Maybe. But what I really want is this:

• Good, well-structured, easy-to-read, proper documentation. Google isn’t doing too bad in this regard, actually, it’s just that they have so much stuff that it’s hard to find what you’re looking for. Hence …
  
• … I want a good search function. Just give me a good fuzzy search for your docs. That’s it.
  

I just don’t have the time or energy to constantly second-guess this stuff. Give me something reliable. Something that is designed to do the right thing, not toy around with probabilities. “AI for everything” is just the wrong approach.

@bender@twtxt.net Of course, I didn’t do anything yet at all. Maybe I will find some time next weekend. Let’s see.

Android shopping list apps disappointed me too many times, so I went back to writing these lists by hand a while ago.

Here’s what’s more fun: Write them in Vim and then print them on the dotmatrix printer. 🥳

And, because I can, I use my own font for that, i.e. ImageMagick renders an image file and then a little tool converts that to ESC/P so I can dump it to /dev/usb/lp0.

(I have so much scrap paper from mail spam lying around that I don’t feel too bad about this. All these sheets would go straight to the bin otherwise.)

Thank you for the encouragement and love and kind words, @lyse@lyse.isobeef.org @movq@www.uninformativ.de @bender@twtxt.net @doesnm@doesnm.p.psf.lt and others along the way I’m not sure of their feed uris 💕 I’ll keep at it, but for the time being I will keep my distance, mostly off IRC, because I don’t have the energy to spare in that kind of engagement (what//if the worst happens, it’s so draining). I need to remember what I ever did any of this for, it was back in ~2020 and I wanted really to build small interconnected communities that any non “tech savvy” person (more or less) could also benefit from ane enjoy. Even if there are aspects of the specs we’ve built/extended over time that aren’t “perfect”™, they’re “good enough”™ that they’ve last 5+ years (I believe this is 6 years running now). I want to spend a bit of time going back to why I did any of this in the the first place, and get a little micro-SaaS offering going (barely covering running costs) so encourage more folks to run pods, and thus twtxt feeds and grow the community ever so slightly. Other than that, I plan to get the specs “in order” to a point (with @movq@www.uninformativ.de and @lyse@lyse.isobeef.org’s help) where I hope they’ll stand the test of time – like SMTP.

Thank you all ! 🙏

Welcome to the party, @threatcat@tilde.club! I reckon it’s totally fine what you’re doing. Over time, message counts naturally drop anyway. :-D And this is fine, too.

@quark@ferengi.one Very sad indeed! :-(

@eldersnake@we.loveprivacy.club Unfortunately, it’s back down again. But my hopes are high as it is a 503 this time and not a connection error anymore. :-)

@prologic@twtxt.net nothing to be sorry about. It gave me time to watch TV with kids! 🤭

Double congrats, @thecanine@twtxt.net! \o/

I’m not a fan of the gemtext limits. This being only a single page (which probably doesn’t get updated a whole lot), the efforts of having two dedicates files are not all that big, or so I’d at least naively imagine.

I always recommend checking the W3C validator results, even though I’m very guilty of not doing that myself. It just doesn’t occur to me in the heat of the moment. I reckon if I were writing HTML on a more regular basis, I would pick up on making that a real habit. Anyway, your HTML being generated, you probably can’t address the findings, though. So, might not be even worth the time heading over to the validator.

From a privacy point of view, personally, I would definitely host the CSS myself. Other than that, nice link collection. :-)

@eldersnake@we.loveprivacy.club What version are you running btw? It’s probably time you upgraded and time I released a new version finally 😂 If you’re running a version that’s pre-SQLite-cache, then yeah I’m not surprised. The SQLite cache version is honestly much better 🤣

@prologic@twtxt.net He’ll be probably back in a few days or weeks I reckon. It’s not the first time that his raspi (or what hardware does he use again?) is down. :-)

… and now I just read @bender@twtxt.net’s other post that said the Gemini text was a shortened version, so I might have criticized things that weren’t true for the full version. Okay, sorry, I’m out. (And I won’t play that game, either. Don’t send me another AI output, possibly tweaked to address my criticism. That is besides the point and not worth my time.)

@prologic@twtxt.net Let’s go through it one by one. Here’s a wall of text that took me over 1.5 hours to write.

This section says AI should not be treated as an authority. This is actually just what I said, except the AI phrased/framed it like it was a counter-argument.

The AI also said that users must develop “AI literacy”, again phrasing/framing it like a counter-argument. Well, that is also just what I said. I said you should treat AI output like a random blog and you should verify the sources, yadda yadda. That is “AI literacy”, isn’t it?

My text went one step further, though: I said that when you take this requirement of “AI literacy” into account, you basically end up with a fancy search engine, with extra overhead that costs time. The AI missed/ignored this in its reply.

Okay, so, the AI also said that you should use AI tools just for drafting and brainstorming. Granted, a very rough draft of something will probably be doable. But then you have to diligently verify every little detail of this draft – okay, fine, a draft is a draft, it’s fine if it contains errors. The thing is, though, that you really must do this verification. And I claim that many people will not do it, because AI outputs look sooooo convincing, they don’t feel like a draft that needs editing.

Can you, as an expert, still use an AI draft as a basis/foundation? Yeah, probably. But here’s the kicker: You did not create that draft. You were not involved in the “thought process” behind it. When you, a human being, make a draft, you often think something like: “Okay, I want to draw a picture of a landscape and there’s going to be a little house, but for now, I’ll just put in a rough sketch of the house and add the details later.” You are aware of what you left out. When the AI did the draft, you are not aware of what’s missing – even more so when every AI output already looks like a final product. For me, personally, this makes it much harder and slower to verify such a draft, and I mentioned this in my text.

You, @prologic@twtxt.net, also mentioned this in your car tyre example.

In my text, I gave two analogies: The gym analogy and the Google Translate analogy. Your car tyre example falls in the same category, but Gemini’s calculator example is different (and, again, gaslight-y, see below).

What I meant in my text: A person wants to be a programmer. To me, a programmer is a person who writes code, understands code, maintains code, writes documentation, and so on. In your example, a person who changes a car tyre would be a mechanic. Now, if you use AI to write the code and documentation for you, are you still a programmer? If you have no understanding of said code, are you a programmer? A person who does not know how to change a car tyre, is that still a mechanic?

No, you’re something else. You should not be hired as a programmer or a mechanic.

Yes, that is “skill evolution” – which is pretty much my point! But the AI framed it like a counter-argument. It didn’t understand my text.

(But what if that’s our future? What if all programming will look like that in some years? I claim: It’s not possible. If you don’t know how to program, then you don’t know how to read/understand code written by an AI. You are something else, but you’re not a programmer. It might be valid to be something else – but that wasn’t my point, my point was that you’re not a bloody programmer.)

Gemini’s calculator example is garbage, I think. Crunching numbers and doing mathematics (i.e., “complex problem-solving”) are two different things. Just because you now have a calculator, doesn’t mean it’ll free you up to do mathematical proofs or whatever.

What would have worked is this: Let’s say you’re an accountant and you sum up spendings. Without a calculator, this takes a lot of time and is error prone. But when you have one, you can work faster. But once again, there’s a little gaslight-y detail: A calculator is correct. Yes, it could have “bugs” (hello Intel FDIV), but its design actually properly calculates numbers. AI, on the other hand, does not understand a thing (our current AI, that is), it’s just a statistical model. So, this modified example (“accountant with a calculator”) would actually have to be phrased like this: Suppose there’s an accountant and you give her a magic box that spits out the correct result in, what, I don’t know, 70-90% of the time. The accountant couldn’t rely on this box now, could she? She’d either have to double-check everything or accept possibly wrong results. And that is how I feel like when I work with AI tools.

Gemini has no idea that its calculator example doesn’t make sense. It just spits out some generic “argument” that it picked up on some website.

The AI makes two points here. The first one, I might actually agree with (“bad bot behavior is not the fault of AI itself”).

The second point is, once again, gaslighting, because it is phrased/framed like a counter-argument. It implies that I said something which I didn’t. Like the AI, I said that you would have to adjust the copyright law! At the same time, the AI answer didn’t even question whether it’s okay to break the current law or not. It just said “lol yeah, change the laws”. (I wonder in what way the laws would have to be changed in the AI’s “opinion”, because some of these changes could kill some business opportunities – or the laws would have to have special AI clauses that only benefit the AI techbros. But I digress, that wasn’t part of Gemini’s answer.)

Except for one point, I don’t accept any of Gemini’s “criticism”. It didn’t pick up on lots of details, ignored arguments, and I can just instinctively tell that this thing does not understand anything it wrote (which is correct, it’s just a statistical model).

And it framed everything like a counter-argument, while actually repeating what I said. That’s gaslighting: When Alice says “the sky is blue” and Bob replies with “why do you say the sky is purple?!”

But it sure looks convincing, doesn’t it?

This took so much of my time. I won’t do this again. 😂

This brings a thought I had for a long time, why can’t we upload arbitrary files to a twtxt? If not an image, make it simply a link. I could have used such feature to upload the text.
