Show HN: I built 80 mini-games using Fable before it was shut down
Dear Hacker News,

I’m kindly asking for your participation in the open beta for my AI-managed mini-games website. Thank you in advance!

For a limited time window, I’m setting the all-free feature flag to true. I hope you have a lot of fun exploring the AI’s sense for games! Here and there, I tweaked it to help with visual consistency.

I would be deeply grateful if you opted into analytics.

@movq@www.uninformativ.de I’ve got the same problem that you had the other day: finding past temperature data. But yeah, it looked much warmer than it actually was. Maybe 5°C? Possibly less when I found myself in the snow- and rainstorm in the end.

With the wind, my fingers were frozen. I should have worn gloves. Without them, I could only put my hands in the pockets of my jacket. That didn’t help much, though, because I frequently stopped to take yet another photo, so they cooled off again right away. :-D

Balancing the big/long, closed umbrella under my arm while I had my hands burried was also a little tricky.

First world problems. :-)

@movq@www.uninformativ.de Oh, so just half a millimeter then! :-D That’s plenty these days for everything to shut down, I’m afraid. If only the same élan was still in action as back then:

Image

And here I am watching Mattias Björnström’s gas pedal freezing at full throttle around -40°C. Well, falls apart and gets stuck.

https://www.youtube.com/watch?v=MLgmV15XeSY

I’m not an expert on this subject at all, but I reckon an automatic in addition with all its sensors is much worse than a manual one. All wheel drive, studded tires and diff locked is what one wants in icy situations. :-D

I’ve got sore muscles. The sticky snow couldn’t be pushed, it had to be laborously cleared shovel by shovel. :-D

In my lunch break, I went on a short stroll. Oh boy, walking through deep damp snow is exhausting! There were sections with easily 30 centimeters and more. Some big wind drifts had piled up. Despite melting off quickly in the 4°C, especially turning the trees brown again, the white landscape still looks so nice. I’m glad these road marking sticks finally came in handy for the snow plow guys. :-) The black and orange stripes are 30 cm high.

https://lyse.isobeef.org/waldspaziergang-2026-01-26/

That’s probably it. There’s no significant snowfall announced for the rest of the week and temperatures are supposed to stay in the 2-4°C range by day.

@movq@www.uninformativ.de I was also extremely surprised and couldn’t believe it myself. But around the hair were definitely two, three millimeters of ice with a bunch of snow on top. I couldn’t simply brush it off, the hair were all frozen together. Back in the house, it took maybe three minutes to melt the solidified white stuff and free up and disconnect the individual hair. Crazy.

Yeah, 0°C in town, maybe -2°C on the summit. It definitely didn’t feel all the cold, but I came prepared with a few layers of cloth.

@lyse@lyse.isobeef.org Ohh, Winter Wonderland. Lovely!

Never had frozen hair. 😳 With just around 0°C? 🤔

What a beautiful, beautiful 0°C Sunday arvo and evening! The weather forecast delayed the snow by the minute. An hour or so after it finally started very, very lightly, I headed off for the woods to check out the lake again. Unfortunately, with the fresh snow layer, the crazy wild surface texture of the ice sheet wasn’t visible anymore. But it brought some other nice views and photo opportunities.

I initially thought that I just go for a quick turn. However, with the snowfall a wee bit increasing I was hooked and kept going. Visibility was poor, but the snow blankets just looked too stunning. The road surfaces were quite slippery, so I often just walked alongside the pathways. On downhill slopes I had some good fun sliding down the road on my feet. With varying success. Luckily, I managed not to fall.

On the summit of the mountain the twigs had those absolutely magnificently looking windblown crystal coverings. Awwwwwww! They never get old. It was already getting dark, so the camera was tired and wanted to sleep. The snow program then made use of the flash and I’m quite pleased with how these shots turned out.

Two deer crossed the road in front of me and ran into the woods, that was sight for sore eyes. Although I felt bad that they had to flee from me in this white terrain. By the time I got home, the snow had accumulated around eight centimeters in height, even in town down in the valley. Walking on this fresh snow is just amazing. And I love the sound it makes. Today, the snow consistency must have been just right, because the crushing sound was really loud.

I cannot recall that I had frozen hair and beard before, but today, there was a thick ice buildup. In case I had, it was definitely never this much. Felt really cool.

Enough of this preliminary skirmishing, there ya go: https://lyse.isobeef.org/waldspaziergang-2026-01-25/

My mate and I went on a hike earlier. Yesterday, we had lovely 12°C. But today, it was down to at most 4°C. Oh well. At least the sun was out and and there was just a tiny bit of wind. We knew upfont that scarf, beanie and gloves were mandatory. Especially at the more windy sections like up top the hills. The view was absolutely terrible, but we made the best of it.

With the sun shining on us during our lunch break at a forest edge bench, we still enjoyed the lookout in 01. I brought some old carpet scraps to sit on and was happily surprised that they isolated even better than I had hoped for. Some hot tea helped us staying warm.

After five hours we returned just after sunset. I’m quite tired now, completely out of shape.

@prologic@twtxt.net I’d love to take a look at the code. 😅

I’m kind of curious to know how much Assembly I need vs. How much of a microkernel can I build purely in Mu (µ)? 🤔

Can’t really answer that, because I only made a working kernel for 16-bit real mode yet. That is 99% C, though, only syscall entry points are Assembly. (The OpenWatcom compiler provides C wrappers for triggering software interrupts, which makes things easier.)

But in long mode? No idea yet. 😅 At least changing the page tables will require a tiny little bit of Assembly.

Vacation: Doing crazy things like C on DOS, lots of Rust, bare-metal assembly code, everything is fine.

Back at work: How the fuck do I move an email in this web mail program? Am I stupid? 😮‍💨

@bender@twtxt.net They’re not completely impossible, but C makes it much easier to run into them. I think the key point is that in those “safe” languages, buffer overflows are caught and immediately crash the program (if not handled otherwise) instead of silently corrupting memory, not being noticed right away and maybe only later crashing at a different location, where it can be very hard to find the actual root cause. This is a big improvement in my book.

Some programmers are indeed horrible. I’m guilty myself. :-)

I like the article.

I came across this on “Why Is SQLite Coded In C”, which I found interesting:

“There has lately been a lot of interest in “safe” programming languages like Rust or Go in which it is impossible, or is at least difficult, to make common programming errors like memory leaks or array overruns.”

If that’s true, then encountering those issues means the programmer is, simply, horrible?

@shinyoukai@neko.laidback.moe Oh no, fuck that 🤣 That’s why I built an FFI so I can call C-functions via shared libraries 🤣

Mu (µ) is now getting much closer to where I want it to be, it now has:

• A process stdlib module (very basic, but it works)
  
• An ffi stdob module that supports dlopen / dlsym and calling C functions with a nice mu-esque wrapper ffi.fn(...)
  
• A sqlite stdlib module (also very basic) that shows off the FFI capabilities

It would be cool to have something like Turbo Vision eventually.

My little toy operating system from last year runs in 16-bit Real Mode (like DOS). Since I’ve recently figured out how to switch to 64-bit Long Mode right after BIOS boot, I now have a little program that performs this switch on my toy OS. It will load and run any x86-64 program, assuming it’s freestanding, a flat binary, and small enough (< 128 KiB code, only uses the first 2 MiB of memory).

Here I’m running a little C program (compiled using normal GCC, no Watcom trickery):

https://movq.de/v/b27ced6dcb/los86%2D64.mp4

Next steps could include:

• Use Rust instead of C for that 64-bit program?
  
• Provide interrupt service routines. (At the moment, it just keeps interrupts disabled.)

I like this. You get performance that’s more or less in the ballpark of C, but without the footguns.

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 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.

@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.

FTR, I see one (two) issues with PyQt6, sadly:

1. The PyQt6 docs appear to be mostly auto-generated from the C++ docs. And they contain many errors or broken examples (due to the auto-conversion). I found this relatively unpleasent to work with.
   
2. (Until Python finally gets rid of the Global Interpreter Lock properly, it’s not really suited for GUI programs anyway – in my opinion. You can’t offload anything to a second thread, because the whole program is still single-threaded. This would have made my fractal rendering program impossible, for example.)

B-/C+ - black and white icons, favicons. I did it before it was cool, but it’s getting overused.

E - gradientslop, barely started, already all blends together.

@movq@www.uninformativ.de Yeah, give it a shot. At worst you know that you have to continue your quest. :-)

Fun fact, during a semester break I was actually a little bored, so I just started reading the Qt documentation. I didn’t plan on using Qt for anything, though. I only looked at the docs because they were on my bucket list for some reason. Qt was probably recommended to me and coming from KDE myself, that was motivation enough to look at the docs just for fun.

The more I read, the more hooked I got. The documentation was extremely well written, something I’ve never seen before. The structure was very well thought out and I got the impression that I understood what the people thought when they actually designed Qt.

A few days in I decided to actually give it a real try. Having never done anything in C++ before, I quickly realized that this endeavor won’t succeed. I simply couldn’t get it going. But I found the Qt bindings for Python, so that was a new boost. And quickly after, I discovered that there were even KDE bindings for Python in my package manager, so I immediately switched to them as that integrated into my KDE desktop even nicer.

I used the Python KDE bindings for one larger project, a planning software for a summer camp that we used several years. It’s main feature was to see who is available to do an activity. In the past, that was done on a large sheet of paper, but people got assigned two activities at the same time or weren’t assigned at all. So, by showing people in yellow (free), green (one activity assigned) and red (overbooked), this sped up and improved the planning process.

Another core feature was to generate personalized time tables (just like back in school) and a dedicated view for the morning meeting on site.

It was extended over the years with all sorts of stuff. E.g. I then implemented a warning if all the custodians of an activitiy with kids were underage to satisfy new the guidelines that there should be somebody of age.

Just before the pandemic I started to even add support for personalized live views on phones or tablets during the planning process (with web sockets, though). This way, people could see their own schedule or independently check at which day an activity takes place etc. For these side quests, they don’t have to check the large matrix on the projector. But the project died there.

Here’s a screenshot from one of the main views:

This Python+Qt rewrite replaced and improved the Java+Swing predecessor.

@lyse@lyse.isobeef.org Hmmmmmmmmmmmm … guess I should take a look at Qt. 🤔 That’s the one popular toolkit that I’ve never really tried for some reason. I really don’t like C++ (might as well use Rust), so I’ll also use Python.

@movq@www.uninformativ.de Don’t you worry, this was meant as a joke. :-D

There was a time when I thought that Swing was actually really good. But having done some Qt/KDE later, I realized how much better that was. That were the late KDE 3 and early KDE 4 days, though. Not sure how it is today. But back then it felt Trolltech and the KDE folks put a hell lot more thought into their stuff. I was pleasantly surprised how natural it appeared and all the bits played together. Sure, there were the odd ends, but the overall design was a lot better in my opinion.

To be fair, I never used it from C++, always the Python bindings, which were considerably more comfortable (just alone the possibility to specify most attributes right away as kwargs in the constructor instead of calling tons of setters). And QtJambi, the Java binding, was also relatively nice. I never did a real project though, just played around with the latter.

37C3 and New Year’s Eve 2023
Another one from the vaults. The 37C3 conference took place in
December, 2023. This report was mostly written in January, 2024.
Mostly finished it at night in my cottage between 28 and 29th
December, then edited and added some stuff in July, 2025. So… Only
1.5 years late?

It was a little ironic, and a little sad, that I was finishing the
37C3 report during 38C3. I didn’t manage to get any tickets for me and
#3 for 38C3 and had to make do with watching the stream.

Here’s an example of X11/Xlib being old and archaic.

X11 knows the data type “cardinal”. For example, the window property _NET_WM_ICON (which holds image data for icons) is an array of “cardinal”. I am already not really familiar with that word and I’m assuming that it comes from mathematics:

https://en.wikipedia.org/wiki/Cardinal_number

(It could also be a bird, but probably not: https://en.wikipedia.org/wiki/Cardinalidae)

We would probably call this an “integer” today.

EWMH says that icons are arrays of cardinals and that they’re 32-bit numbers:

https://specifications.freedesktop.org/wm-spec/latest-single/#id-1.6.13

So it’s something like 0x11223344 with 0x11 being the alpha channel, 0x22 is red, and so on.

You would assume that, when you retrieve such an array from the X11 server, you’d get an array of uint32_t, right?

Nope.

Xlib is so old, they use char for 8-bit stuff, short int for 16-bit, and long int for 32-bit:

https://x.org/releases/current/doc/libX11/libX11/libX11.html#Obtaining_and_Changing_Window_Properties

That is congruent with the general C data types, so it does make sense:

https://en.wikipedia.org/wiki/C_data_types

Now the funny thing is, on modern x86_64, the type long int is actually 64 bits wide.

The result is that every pixel in a Pixmap, for example, is twice as large in memory as it would need to be. Just because Xlib uses long int, because uint32_t didn’t exist, yet.

And this is something that I wouldn’t know how to fix without breaking clients.

st tries not to redraw immediately after new data arrives:

The exact timings are configurable.

This is the PR that changed the timing in VTE recently (2023):

https://gitlab.gnome.org/GNOME/vte/-/issues/2678

There is a long discussion. It’s not a trivial problem, especially not in the context of GTK and multiple competing terminal widgets. st dodges all these issues (for various reasons).

We covered quite some ground in the two and a half hours today. The weather was nice, mostly cloudy and just 23°C. That’s also why we decided to take a longer tour. We saw four deer in the wild, three of which I managed to just ban on film, quality could be better, though. My camera produced a hell lot of defocused photos this time. Not sure what’s going on with the autofocus. https://lyse.isobeef.org/waldspaziergang-2025-07-10/

When the sun came out, colors were just beautiful:

Just realized: One of the reasons why I don’t like “flat UIs” is that they look broken to me. Like the program has a bug, missing pixmaps or whatever.

Take this for example:

Image

I’m talking about this area specifically:

Image

One UI element ends and the other one begins – no “transition” between them.

The style of old UIs like these two is deeply ingrained into my brain:

Image

Image

When all these little elements (borders, handles, even just simple lines, …) are no longer present, then the program looks buggy and broken to me. And I’m not sure if I’ll ever be able to un-learn that.

@movq@www.uninformativ.de @kat@yarn.girlonthemoon.xyz It’s awful, “just” 32°C here. When I rode my bike into town I came across some spots where the heat was stationary built up and really intense. The airflow felt like the sauna attendant poured water over the heated rocks and severely fanned the hot air with his towel.

@prologic@twtxt.net … or just bullshit.

I’m Alex, COO at ColdIQ. Built a $4.5M ARR business in under 2 years.

Some “C-level” guy telling people what to do, yeah, I have my doubts.

@prologic@twtxt.net I’m trying to call some libc functions (because the Rust stdlib does not have an equivalent for getpeername(), for example, so I don’t have a choice), so I have to do some FFI stuff and deal with raw pointers and all that, which is very gnarly in Rust – because you’re not supposed to do this. Things like that are trivial in C or even Assembler, but I have not yet understood what Rust does under the hood. How and when does it allocate or free memory … is the pointer that I get even still valid by the time I do the libc call? Stuff like that.

I hope that I eventually learn this over time … but I get slapped in the face at every step. It’s very frustrating and I’m always this 🤏 close to giving up (only to try again a year later).

Oh, yeah, yeah, I guess I could “just” use some 3rd party library for this. socket2 gets mentioned a lot in this context. But I don’t want to. I literally need one getpeername() call during the lifetime of my program, I don’t even do the socket(), bind(), listen(), accept() dance, I already have a fully functional file descriptor. Using a library for that is total overkill and I’d rather do it myself. (And look at the version number: 0.5.10. The library is 6 years old but they’re still saying: “Nah, we’re not 1.0 yet, we reserve the right to make breaking changes with every new release.” So many Rust libs are still unstable …)

… and I could go on and on and on … 🤣

Nothing makes you feel better than mowing a wet lawn, while rain falls, under 33°C temperature, with 80% humidity. I loved every step I took!
