I was looking at some ancient code and then thought: Hmm, maybe it would be a good idea to see more details in this error message. Which of the values don’t line up. On the other hand, that feature isn’t probably used anyway, because it’s a bit ugly to use (historically evolved). And on top of that, most teams need something slightly different, if they deal with that sort of thing.

I still told my workmates about it, so they could also have a look at it and we can decide tomorrow what to do about it. Speaking of the devil, no kidding, not even half an hour later, a puzzled tester contacted me. She received exactly that rather useless error message. Looks like I had an afflatus. ;-)

It’s interesting, though, that in all those years, nobody stumbled across this before. At least we now know for sure that this is not dead code. :-)

@prologic@twtxt.net FWIW, I love the idea and I do the same with my email domains. It’s the most effective way to fight spam, IMO. 🥳

@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. 😂

@kiwu@twtxt.net hey, not random! How dare you! (with Greta accent, and emphasis). LOL. Old man here doing, well, like old man do. Wait until you are old, and that will give you a better idea. :-P

Java’s Swing is allegedly in “maintenance mode”, so I doubt it’s a good idea to use it for new programs. For example, I very much doubt that it will ever support Wayland.

The replacement is supposed to be JavaFX, but that’s not included in JREs – anymore! It used to be, now it’s not, even though it’s well over 15 years old now.

This whole thing (“Java GUIs”) appears to have stagnated a lot. Probably because everything is web stuff these days …

Erlang Solutions: ​​Expert Insights from Our Latest Webinars
The Erlang Solutions team has been creating webinars that share knowledge, spark ideas, and celebrate the BEAM community. Each one offers a chance to explore new tools, hear fresh perspectives, and learn from the people building scalable and reliable systems every day.

If you haven’t tuned in yet, here’s a look at some of our recent sessions, full of practical insights and new thinking shaping the future of the BEAM.

@prologic@twtxt.net Hmm, I’ll have to take a look. Appears to be Go only, doesn’t it?

I’m not quite sold yet on the idea of “immediate mode” GUIs. 🤔

@movq@www.uninformativ.de he sure does! LOL. It is more like incomprehensible stuff that comes out. Sometimes I manage to get what he was trying to say, but more often than not I have no idea. 🤣

Intranets have been around since Jesus times (well, not quite 😂, but you get the idea). They are fun to play with, but that’s about it. I mean, the “fun” of the Internet comes from its variety.

It happened.

“Can you help me debug this program? I vibe coded it and I have no idea what’s going on. I had no choice – learning this new language and frameworks would have taken ages, and I have severe time constraints.”

Did I say “no”? Of course not, I’m a “nice guy”. So I’m at fault as well, because I endorsed this whole thing. The other guy is also guilty, because he didn’t communicate clearly to his boss what can be done and how much time it takes. And the boss and his bosses are guilty a lot, because they’re all pushing for “AI”.

The end result is garbage software.

This particular project is still relatively small, so it might be okay at the moment. But normalizing this will yield nothing but garbage. And actually, especially if this small project works out fine, this contributes to the shittiness because management will interpret this as “hey, AI works”, so they will keep asking for it in future projects.

How utterly frustrating. This is not what I want to do every day from now on.

@movq@www.uninformativ.de That’s satisfying. :-) Not all my clocks are radio-controlled, though.

I’ve got a digital alarm clock from the Netherlands (no idea where I got this) and it always runs an hour late. No clue. I put it on a shelf in the workshop where it causes the least amount of confusion.

@prologic@twtxt.net Where do I stand on “Chat Control”? How long of a response/rant do you want? 😅 It’s a disaster. As I understand it, they want to spy on me directly on my devices before encryption even happens – jfc, no, fuck off. And since there are so many devices, they want to automate the scanning, which is the worst idea you could possibly have.

Random musing from a #Python creative coder:

I have this naïve cumbersome thing for dealing with collinear vertices in a polygon (like a vertex in the middle of an edge that doesn’t change the shape of the polygon, and I tried to replace it with some clever #shapely method such as .simplify(…) or .buffer(0) and failed miserably. So I’ll have to keep my home made check-area-every-three-vertices thing for now…

I’m kind of proud of my idea of representing polygons as a set of frozensets of edge vertex pairs because it eliminates all visually equivalent rotations and reverse ordered rotations (that is, if you don’t have pesky collinear vertices).

@alexonit@twtxt.alessandrocutolo.it prologic has me sold on the idea of hashv2 being served alongside a text fragment, eg. (#abcdefghijkl https://example.com/tw.txt#:~:text=2025-10-01T10:28:00Z), because it can be simply hacked in to clients currently on hashv1 and provides an off-ramp to location-based addressing (though i still think the format should be changed to smth like #<abc... http://example.com/...> so it’s cleaner once we finally drop hashes)

@prologic@twtxt.net Hm, I don’t know. Over here, we have parties that we would call “left” or “right”, one of them even calls themselves “The Left”. No idea about your political landscape, but it still makes sense for us. 🤔 For me, at least.

@prologic@twtxt.net yup, that’s what I meant. The lack of it on the URL is fine, but on the post itself it is always a good idea. Time frames matter.

Removing the empty cache file and it works again. No idea about the PATH glitch, though. Very strange.

We’ve been discussing the idea of changing the threading model from Content-based Addressing to Location-based addressing for years now. The problem is quite complex, but I feel I have to keep reminding y’all of the potential perils of changing this and the pros/cons of each model:

With content-addressed threading, a reply points at something that’s intrinsically identified (hash of author/feed URI + timestamp + content). That ID never changes as long as the content doesn’t. Switching to location-based anchors makes the reply target extrinsic—it now depends on where the post currently lives. In a pull-based, decentralised network, locations drift. The moment they do, thread identity fragments.

This thing about making software run on other people’s computers can be pretty hard!

No wonder I think I’ve heard this is one of the things that distinguishes professional software development from [my preferred domain of] things such as “end-user programming” etc.

The problem is that when you start sharing code in the context of a FLOSS project you almost immediately get enmeshed in concerns about packaging and how other people will install stuff, when sometimes you just don’t want to be a professional software developer! 😿

I’m always borrowing terms (learning ideas) from @lr like: incidental complexity. I hate incidental complexity or maybe I just fear incidental complexity. Can we escape incidental complexity? I guess not.

@bender@twtxt.net Seriously I have zero clue 🤣 I don’t read or watch any news so I have no idea 🤦‍♂️

The worst thing you can do is make your infrastructure (switches, wifi, …) depend on some cloud service. Because someone else is maintaining that service; you have no control over it. You 100% depend on that other person now. Very stupid idea.

Now guess what manufacturers are pushing for …

Now guess who couldn’t complete a task at work this Saturday morning, because a certain cloud service was down …

IT is fucked. Throw it all away and start over.

at first i dismissed the idea of likes on twtxt as not sensible…like at all — then i considered they could just be published in a metadata field (though that field could get really unruly after a while)

retwts are plausible, as “RE: https://example.com/twtxt.txt#abcdefg”, the hash could even be the original timestamp from the feed to make it human readable/writable, though im extremely wary of clogging up timelines

i thought quote twts could be done extremely sensibly, by interpreting a mention+hash at the end of the twt differently to when placed at the beginning — but the twt subject extension requires it be at the beginning, so the clean fallback to a normal reply i originally imagined is out of the question — it could still be possible (reusing the retwt format, just like twitter!) but i’m not convinced it’s worth it at that point

is any of this in the spirit of twtxt? no, not in the slightest, lmao

@dce@hashnix.club Apart from the crap produced in Redmond two decades ago, I only ever used and still happily use Linux, mainly Debian and Ubuntu. I’ve no idea, but maybe something in there catches your eye: https://en.wikipedia.org/wiki/List_of_operating_systems (I know, what a silly recommendation.)

There’s always something more urgent: I’ve been known for a long time that sooner or later I’d feel prompted to switch from #github to somewhere else (since 2018 at least!), but I’ve been postponing and only very slowly flirting with the idea… That didn’t work too bad for me: if I had rushed into it I would have probably migrated to #gitlab, before knowing about the more objectionable sides to it. In the end, 2025 was the year I finally acted upon the urge to move. I did not do a very thorough analysis of the alternative hosts - what I have been reading about them along the years felt enough, and I easily decided to choose #codeberg. Being hasty like that, alas, was a mistake: I just now found - during this slow and time-consuming process of deciding what and how to migrate - that there is a low repository limit on codeberg: “The owner has already reached the limit of 100 repositories.” I’m not complaining, mind you, and those “lucky 100” that are already there will stay - at least as a sort of backup. But this means that codeberg is not for me - and so this time I turn to you, the #mastodon community.

What github alternative, not self-hosted, should I move my >100 projects into?

@movq@www.uninformativ.de Hahaha, great idea! :-D I never saw the Epson Image Scan logo before.

I’ve got a prototype of my hardcopy simulator going. I’m typing on the keyboard and the “display” goes to the printer:

The biiiiiiiiiig problem is that the print head and plastic cover make it impossible to see what’s currently being printed, because this is not a typewriter. This means: In order to see what I just entered, I have to feed the paper back and forth and back and forth … it’s not ideal.

I got that idea of moving back/forth from Drew DeVault, who – as it turned out – did something similar a few years back. (I tried hard to read as little as possible of his blog post, because figuring things out myself is more fun. But that could mean I missed a great idea here or there.)

But hey, at least this is running on my Pentium 133 on SuSE Linux 6.4, printer connected with a parallel cable. 😍

(Also, yes, you can see the printouts of earlier tests and, yes, I used ed(1) wrong at one point. 🤪 And ls insisted on using colors …)

In order to publish my personal projects/pages (and most of my teaching materials, hundreds of pages) on #Codeberg, I need to convert #markdown files into #HTML and sprinkle some CSS & JS from a layout template, like #GitHub’s Pages #Jekyll does, but I dread the complexity of installing and tending to Jekyll or Hugo or other static site generators, and I can’t even imagine going near Forejo Actions or any sort of CI intergration.

Should I be brave and do the Jekyll /static generator thing? Any other ideas for poor, overworked, stressed out, clumsy people? :(

My next try with twtxt - because it’s the closest to my idea of microblogging.

@kat@yarn.girlonthemoon.xyz I have absolutely no idea, but I wouldn’t be surprised if it uses the closest full image after your cut point and not the one before. Hence, the deltas between the two full images have nothing to really refer to. So, the video player just shows the first full image it finds and “freezes” the image until the video stream actually hits it.

Let me try to visualize it, | represent full images, . just subsequent deltas:

Original start of video
↓
|......|.....|........|......|..
   ↑                      ↑
   Cut point      Cut point

Resulting video:

   ....|.....|........|....
   ↑↑↑↑
   This is where it freezes         

Could be complete bullshit, though. Wouldn’t be the first time that I’m wrong. :-)

I’m just curious, what exact command line do you use to cut the video?

@lyse@lyse.isobeef.org yesss it’s not my idea but it’s sooo fun here ngl like i should use it more!!

@movq@www.uninformativ.de That’s an interesting idea. For privacy, I’d just omit the Referer altogether. But maybe this helps talking to misconfigured HTTP servers that reject requests without such a header. No clue.

@lyse@lyse.isobeef.org Hm, I don’t think so, the requested page was a Linux-specific post. 🤔 I sometimes wonder if privacy-oriented browsers might do this on purpose, to create garbage data? 🤔 No idea.

Something happened with the frame rate of terminal emulators lately. It looks like there’s a trend to run at a high framerate now? I’m not sure exactly. This can be seen in VTE-based terminals like my xiate or XTerm on Wayland. foot and st, on the other hand, are fine.

My shell prompt and cursor look like this:

$ █

When I keep Enter pressed, I expect to see several lines like so:

$
$
$
$
$
$
$ █

With the affected terminal emulators, the lines actually show up in the following sequence. First, we have the original line:

$ █

Pressing Enter yields this as the next frame:

$
█

And then eventually this:

$
$ █

In other words, you can see the cursor jumping around very quickly, all the time.

Another example: Vim actually shows which key you just pressed in the bottom right corner. Keeping j pressed to scroll through a file means I get to see a j flashing rapidly now.

(I have no idea yet, why exactly XTerm in X11 is fine but flickering in Wayland.)

@prologic@twtxt.net @bender@twtxt.net That’s what I thought as well, sounds way too expensive to me. But I have no idea what the prices are over here. Probably also astronomical. Campers sit around most of the time, one really would need to use them a lot to justify spending so much money on them.

But yeah, each to their own (expensive) hobbies. :-) I, for example, burn my money on tools that I don’t really™ need. :-P

@prologic@twtxt.net Yeah, this really could use a proper definition or a “manifest”. 😅 Many of these ideas are not very wide spread. And I haven’t come across similar projects in all these years.

Let’s take the farbfeld image format as an example again. I think this captures the “spirit” quite well, because this isn’t even about code.

This is the entire farbfeld spec:

farbfeld is a lossless image format which is easy to parse, pipe and compress. It has the following format:

╔════════╤═════════════════════════════════════════════════════════╗
║ Bytes  │ Description                                             ║
╠════════╪═════════════════════════════════════════════════════════╣
║ 8      │ "farbfeld" magic value                                  ║
╟────────┼─────────────────────────────────────────────────────────╢
║ 4      │ 32-Bit BE unsigned integer (width)                      ║
╟────────┼─────────────────────────────────────────────────────────╢
║ 4      │ 32-Bit BE unsigned integer (height)                     ║
╟────────┼─────────────────────────────────────────────────────────╢
║ [2222] │ 4x16-Bit BE unsigned integers [RGBA] / pixel, row-major ║
╚════════╧═════════════════════════════════════════════════════════╝

The RGB-data should be sRGB for best interoperability and not alpha-premultiplied.

(Now, I don’t know if your screen reader can work with this. Let me know if it doesn’t.)

I think these are some of the properties worth mentioning:

• The spec is extremely short. You can read this in under a minute and fully understand it. That alone is gold.
  
• There are no “knobs”: It’s just a single version, it’s not like there’s also an 8-bit color depth version and one for 16-bit and one for extra large images and one that supports layers and so on. This makes it much easier to implement a fully compliant program.
  
• Despite being so simple, it’s useful. I’ve used it in various programs, like my window manager, my status bars, some toy programs like “tuxeyes” (an Xeyes variant), or Advent of Code.
  
• The format does not include compression because it doesn’t need to. Just use something like bzip2 to get file sizes similar to PNG.
  
• It doesn’t cover every use case under the sun, but it does cover the most important ones (imho). They have discussed using something other than RGBA and decided it’s not worth the trouble.
  
• They refrained from adding extra baggage like metadata. It would have needlessly complicated things.

@movq@www.uninformativ.de Yeah that’s why I’m striking this conversation with you 😅 Not only do I respect your opinion quite highly 🤣 But like you say (and I’ve read their philipshpy) it can be a bit “elitism” for sure. I’m genuinely interested in what we think of as software that “doesn’t suck”. Tb be honest I haven’t really put thought to paper myself, but I reckon if I did, I’d have some opinions/ideas…

I’m watching #TheOrville. Some ideas are interesting but the sense of humor isn’t really to my taste. Maybe a bit on the nose, could I phrase it that way? And the clumsy stuff makes me feel nervous instead of making me laugh.

In all fairness, GOG says that Forsaken is only supported on Ubuntu 16.04 – not current Arch Linux. If you ask me, this just goes to show that Linux is not a good platform for proprietary binary software.

Is it free software, do you have the source code? Then you’re good to go, things can be patched/updated (that can still be a lot of work). But proprietary binary blobs? Very bad idea.

I was wondering: What the heck is the light on my boot!? Turns out between sock and shoe tongue was a firefly, unbelievable! ;-D I’ve no idea how that happened. After untying, it took me five attempts to finally get it off. How crazy!

Watching several hundred glowworms tonight did not get boring. It’s just so damn cool. :-)

@movq@www.uninformativ.de I also don’t think that I’m a particularly good speaker. :-) The workshop model is a good idea, I like that.

Yeah, it’s really good fun. I can highly recommend it. This is also a good way to train (new) developers to think like attackers, how to break in, destroy something or raise awareness of some classes of bugs. Then you can avoid them next time. It’s surprising to me what vulnerabilities come up during this event every time. So, absolutely worth it, win, win.

Okay, here’s a thing I like about Rust: Returning things as Option and error handling. (Or the more complex Result, but it’s easier to explain with Option.)

fn mydiv(num: f64, denom: f64) -> Option<f64> {
    // (Let’s ignore precision issues for a second.)
    if denom == 0.0 {
        return None;
    } else {
        return Some(num / denom);
    }
}

fn main() {
    // Explicit, verbose version:
    let num: f64 = 123.0;
    let denom: f64 = 456.0;
    let wrapped_res = mydiv(num, denom);
    if wrapped_res.is_some() {
        println!("Unwrapped result: {}", wrapped_res.unwrap());
    }

    // Shorter version using "if let":
    if let Some(res) = mydiv(123.0, 456.0) {
        println!("Here’s a result: {}", res);
    }

    if let Some(res) = mydiv(123.0, 0.0) {
        println!("Huh, we divided by zero? This never happens. {}", res);
    }
}

You can’t divide by zero, so the function returns an “error” in that case. (Option isn’t really used for errors, IIUC, but the basic idea is the same for Result.)

Option is an enum. It can have the value Some or None. In the case of Some, you can attach additional data to the enum. In this case, we are attaching a floating point value.

The caller then has to decide: Is the value None or Some? Did the function succeed or not? If it is Some, the caller can do .unwrap() on this enum to get the inner value (the floating point value). If you do .unwrap() on a None value, the program will panic and die.

The if let version using destructuring is much shorter and, once you got used to it, actually quite nice.

Now the trick is that you must somehow handle these two cases. You must either call something like .unwrap() or do destructuring or something, otherwise you can’t access the attached value at all. As I understand it, it is impossible to just completely ignore error cases. And the compiler enforces it.

(In case of Result, the compiler would warn you if you ignore the return value entirely. So something like doing write() and then ignoring the return value would be caught as well.)

@kat@yarn.girlonthemoon.xyz I might give it a shot. 😃

Skimming through the manual: I had no idea that keeping the “up” cursor pressed actually slows you down at some point. 🤦

@movq@www.uninformativ.de I like this idea 👌 Very neat!

@prologic@twtxt.net will do. No worries, not a show stopper. I will suggest that the muted numbered list not be sorted, but latest muted first. That way we have a better idea. Maybe adding timestamps to those too? Just a thought.

How can one write blazing fast yet useful compilers (for lazy pure functional languages)?
I’ve decided enough is enough and I want to write my own compiler (seems I caught a bug and lobste.rs is definitely not discouraging it). The language I have in mind is a basic (lazy?) statically-typed pure functional programming language with do notation and records (i.e. mostly Haskell-lite).

How to Adjust Font Smoothing in macOS Sequoia & macOS Sonoma
Font Smoothing is a longstanding feature in MacOS that aims to make rendered screen text more legible, and it works by subtly blending the edges of display fonts with the background by using anti-aliasing. The idea is to reduce the jaggedness of screen text, but in practice nowadays it basically makes screen fonts on the … [Read More](https://osxdaily.com/2025/06/04/how-adjust-font-smoothing-macos-sequoia-sonoma-v … ⌘ Read more

Ten Outlandish Ideas to Deal with Nuclear Waste
Toxic waste is an urgent issue. Nuclear power plants provide nearly 20% of all electricity in the United States, and many of us rely on them around the world.

@kat@yarn.girlonthemoon.xyz Ta! The dead end wasn’t all that bad in my opinion. Personally, I really do like dirt paths and exploring. It was all dried up, so no muddy mess we had to walk through. More like climbing over thick branches that have been worked into the ground by harvesters or forwarders in the muddy winter. Rough terrain. My mate, on the other hand – whose idea it was to check out the real summit in the first place ;-) — wasn’t all that pleased about the detour. Oh well. :-D

To follow up what I said minutes ago, they don’t even want you to think of the initial idea, they want you to be a mindless organism, the AI algorithm analyses and tells what you should make, down to the script, so that you get the highest number of people possible to click it and see some AI generated advertisement, blended seemly into what’s no lonher even your work.

sooo many ideas for my site now that it’s SSG powered, not enough energy….. i wanna make little content collections but no energy T__T also i only half know what content i wanna put in them lol!

@kat@yarn.girlonthemoon.xyz come on! Stop giving me ideas when I’m bored, specially when there’s a sewing machine in a room next to mine xD

Thanks to @kat@yarn.girlonthemoon.xyz and her shelf I finally spent several hours in the woodshop. I wanted to build two drawers for the workbench and thought that I will complete this project in no time. I’ve been so wrong again. ;-)

I didn’t draw any plans, just measured a few times and then went to cutting a bunch of particle board leftovers at the table saw. I routed rebates on the sides, fronts and backs to lap the boxes and sink in the bottom. It turned out that having no plans was a stupid idea. I cut exactly on the lines as I calculated and measured, however, the math in my head fell apart when it eventually met reality. The bottoms are too short, so I gotta glue on some strips. Also, with the longer fronts, the sides won’t work either, I have to fix them as well. :-D

Finally, the lid of my cyclone bucket broke when the negative pressure got too large. Oh well. It was just an old wood glue bucket, I’ve got another empty one, so I can use that lid but strengthen it first with some plywood. Something for future Lyse to deal with.

All in all, it was still good fun. Wood (haha) do it again, but at least with some sketches on paper. ;-)

Which AI “arena” is the one we can actually trust?
I’m getting deeper and deeper into the AI space, and I’m discovering the different AI “arenas” and benchmarking. I have no idea what to trust or leverage to help me learn about the different models out there. Does the lobste.rs community have one that they go to by default? ⌘ Read more

@kat@yarn.girlonthemoon.xyz Any idea why?

@bender@twtxt.net I think this would be a good idea as @movq@www.uninformativ.de and @andros@twtxt.andros.dev have done ✅ I may even join the experiments if I have any spare time to hack a custom yrand branch and run it up on say something like a yarnexp.mills.io or something 🤔

@sorenpeter@darch.dk Yes, there are interesting things that can be incorporated to see how they work.
The issue of allowing the use of Z for UTC is interesting. I think I should add a brief explanation.
The url issue is for a debate :D . Maybe an issue could be opened. My opinion is that it is necessary to leave it as it is right now because otherwise the thread system, or replies, may have problems (404s). It’s all a matter of discussion.
I like your idea of contact. I will add it.
Thanks to you for your feedback!!!

@andros@twtxt.andros.dev Thanks for consolidating a lot of good ideas. Especially how you have deiced to just extend the mention syntax for location-based treads. This might even be backward compatible with older (pre-yarn) clients.
What about using Z for UTC +00:00- is that allowed in your specs?
Regarding url = I would suggest to only allow one and the maybe add url_old = or url_alt = !?
I’m still not a fan of a DM feature, even thou it helps that i have now been split out into a separate feed file. Instead if would suggest a contact = field for where people can put an email or other id/link for an established chat protocol like signal or matrix.

10 Critical Bottlenecks in Modern Civilization Posing a Major Risk
We like to think modern civilization is robust, backed by endless redundancy.

@kat@yarn.girlonthemoon.xyz Off-topic areas are always a good idea. :-) Web forums often had those. And web forums are actually what I had in mind, @bender@twtxt.net. 😅 (While I do have a certain nostalgia for it now, Usenet has always been a bit weird to me. Can’t really explain why.)

So, the “AI” bots have reached my website. Looks like they’re just slowly crawling everything at the moment – no DDoS-like attack yet. I wonder if that has something to do with my website being 100% static HTML. There are no GET parameters they can tweak and, at the end of the day, there’s not that much data on my server anyway … And maybe they have no idea what stagit is, so it doesn’t trigger “standard behavior”, like “this is a Gitea instance, let’s crawl this like crazy!”?

@lyse@lyse.isobeef.org Kind of, but on the other hand: This twt right here refers to 3rvya6q and your feed, but your feed certainly does not include that particular twt (it comes from my feed).

But my proposal probably isn’t very helpful, either. We have this flat conversation model, so … this twt right here, what should it refer to? Your twt? My root twt? I don’t know.

@prologic@twtxt.net Don’t include this just yet. I need to think about this some more (or drop the idea).

If we must stick to hashes for threading, can we maybe make it mandatory to always include a reference to the original twt URL when writing replies?

Instead of

(<a href="https://txt.sour.is/search?q=%23123467">#123467</a>) hello foo bar

you would have

(<a href="https://txt.sour.is/search?q=%23123467">#123467</a> http://foo.com/tw.txt) hello foo bar

or maybe even:

(<a href="https://txt.sour.is/search?q=%23123467">#123467</a> 2025-04-30T12:30:31Z http://foo.com/tw.txt) hello foo bar

This would greatly help in reconstructing broken threads, since hashes are obviously unfortunately one-way tickets. The URL/timestamp would not be used for threading, just for discovery of feeds that you don’t already follow.

I don’t insist on including the timestamp, but having some idea which feed we’re talking about would help a lot.

July 1st. 63 days from now to implement a backward-incompatible change, apparently not open to other ideas like replacing blake with SHA, or discussing implementation challenges for other languages and platforms.
Finally just closing #18, #19 and #20 without starting a proper discussion and ignoring a ‘micro consensus’ feels… not right.

I don’t know what to think rather than letting it rest (May will be busy here) and focus on other stuff in the future.

@movq@www.uninformativ.de Agreed, finding the right motivation can be tricky. You sometimes have to torture yourself in order to later then realize, yeah, that was actually totally worth it. It’s often hard.

I think if you find a project or goal in general that these kids want to achieve, that is the best and maybe only choice with a good chance of positive outcome. I don’t know, like building a price scraper, a weather station or whatever. Yeah, these are already too advanced if they never programmed, but you get the idea. If they have something they want to build for themselves for their private life, that can be a great motivator I’ve experienced. Or you could assign ‘em the task to build their own twtxt client if they don’t have any own suitable ideas. :-)

Showing them that you do a lot of your daily work in the shell can maybe also help to get them interested in text-based boring stuff. Or at least break the ice. Lead by example. The more I think about it, the more I believe this to be very important. That’s how I still learn and improve from my favorite workmate today in general. Which I’m very thankful of.
