↳ In-reply-to » @movq Thanks. I noticed the <updated> of the feed, too. But for some reason, some articles were suddenly marked as new.

Aha, yesterday’s newly added support for LC_TIME to render localized timestamps also broke the feed parsing with my LANG=de_DE.UTF-8 and LC_CTYPE=de_DE.UTF-8 environment. :-)

Atom feeds make use of RFC 3339 timestamps. They are first converted into RFC 882 timestamp representation, which is the one that RSS feeds use. However, this conversion now results in localized RFC 882 timestamps, which cannot be parsed into Unix timestamp numbers via curl_getdate(…). I bet that it doesn’t know about the localization at all and expects English month and weekday names. Looking at its docs, I reckon that function was selected because of its myriad of supported timestamp formats: https://curl.se/libcurl/c/curl_getdate.html RFC 3339 is not included, though, hence the transformation up front.

The intermediate Item objects in the parser domain use std::string for the timestamp representation. This isn’t all that silly, because Newsboat supports all sorts of different feed formats with different timestamp formats. These RFC 883 timestamps are centrally parsed into time_t.

Speaking of time: It’s time to go to bed after this late bug hunting fun. :-)

↳ In-reply-to » You didn't change your Atom feed by any chance yesterday or today, @movq? Not only do I have a metric shitton of "new" old items in my YouTube feeds, but also a bunch of your old articles are shown as new.

@lyse@lyse.isobeef.org Uhhh, yes, I have one single script to build the website and I ran that while writing that noai.html page. Apart from the global updated field in my feeds (that one got changed), everything else should be stable, though.

Maybe this helps narrow things down?

I just missed the 20 year anniversary of my blog. 😬 What a stupid long time to do this.

This started out as a PHP page with user comments, MySQL as a database, a PHP webadmin … can you believe that? Totally unnecessary. But everything was “LAMP” back then, so that’s what I was using as well. I kicked out MySQL in 2011 (it just stored files since then) and eventually switched to static HTML pages in 2015.

RSS feeds have only been there since 2009, because I was late to the party. For a long time, I didn’t understand what they were good for. 🤦

@tftp@tilde.town mentioning in here requires he whole shebang. With jenny, if using vim, there is a key combination:

Nick name completions: Allows you to use ^X ^U to turn verbatim nick names into full twtxt mentions. For example, typing “cath” and then pressing ^X ^U will turn “cath” into a full mention, like “@”. (This function will read the contents of your “~/.config/jenny/follow” file.)

Disclaimer: Can’t guarantee that I’m fully awake and I’m being trained at work not to use my brain anymore, so maybe this is complete bullshit. 😪🧟‍♀️

It says here that SQLite uses signed integers:

https://sqlite.org/datatype3.html

In pure bits, 1 << 63 would be 0x8000000000000000, but as a signed value, it gets interpreted as -9223372036854775808. Subtracting 1 yields -9223372036854775809 – but that doesn’t fit in 64 bits anymore. It’s possible that SQLite doesn’t want to wrap around but instead saturates? Haven’t checked. 🤔

With 62 bits, there is enough room.

With 1 << 64, I have no idea how SQLite wants to handle this, because this should immediately trigger a warning, because it doesn’t fit right away. Maybe it gets truncated to 0?

sqlite> select printf('0x%x', 2 * (1 << 64));

In the interest of fairness and hopefully for the last time, I ever have to address this, Google has flip-flopped again and promised “sideloading” will not be removed from their version of Android, but instead have to be enabled in the developer settings, using the following “advanced flow”:

To be perfectly clear, this still falls short of what I wanted, but at this point, it is a compromise I’m willing to take, over further pursuing this, through the various available European courts, myself.

@lyse@lyse.isobeef.org Thanks for letting me know. HTML checkers seem happy now. I’m not sure what to do about the images not loading. The photos have three sizes (thumbnail, photo page, and original if you click the img tag on the photo page); can you at least see the smaller two sizes? Maybe I will do some experimental fetches and/or start measuring things on my web server.

Fuck me dead! I accidentally confused an HTML file for a YAML file and manually opened it in my browser. Unfortunately, I clicked on the OK button of the popped up dialog a bit too fast, it just caught me off guard. It asked which program to open the YAML file in. Of course Firefox thought that it could handle that and suggested itself by default. Conveniently, the “don’t prompt me again and always use this selection from now on” checkbox was enabled.

And then the endless loop of death started. Turns out, this fucking browser can’t do shit with YAML files and delegated to what had been just configured. Oh, would you look at that!? Firefox! Empty tabs after empty tabs appeared. Killing and restarting Firefox just loaded the last session with all the tabs and the loop continued.

Some bloody snakeoil on my work machine slows down link openening requests by two, three seconds. It’s always absolutely anoying, but luckily, it actually limited the rate of new tabs popping up. I still could not close the many tabs fast enough that had accumulated before I noticed what was going on in the background.

Going to the settings to change them was always interrupted with a new tab opening in the foreground.

Finally, killing Firefox and renaming the file on disk before restarting Firefox did the trick and broke the loop. I was still holding down Ctrl+W for a minute or so to get rid of the useless tabs. I didn’t want to loose the important tabs, so just ditching the session wasn’t an option.

↳ In-reply-to » Btw @movq you've inspired me to try and have a good 'ol crack at writing a bootloader, stage1 and customer microkernel (µKernel) that will eventually load up a Mu (µ) program and run it! 🤣 I will teach Mu (µ) to have a ./bin/mu -B -o ... -p muos/amd64 ... target.

@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.

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?

↳ In-reply-to » More widget system progress:

And now the event loop is not a simple loop around curses’ getch() anymore but it can wait for events on any file descriptor. Here’s a simple test program that waits for connections on a TCP socket, accepts it, reads a line, sends back a line:

https://movq.de/v/93fa46a030/vid-1767547942.mp4

And the scrollbar indicators are working now.

I’ll probably implement timer callbacks using timerfd (even though that’s Linux-only). 🤔

@movq@www.uninformativ.de I noticed that your feed’s last modification timestamp was missing in my database. I cannot tell for certain, but I think it did work before. Turns out, your httpd now sends the Last-Modified with UTC instead of GMT. Current example:

Sat, 03 Jan 2026 06:50:20 UTC

I’m not a fan of this timestamp format at all, but according to the HTTP specification, HTTP-date must always use GMT for a timezone, nothing else: https://httpwg.org/specs/rfc9110.html#http.date

↳ In-reply-to » On my way to having windows and mouse support:

At around 19 seconds in the video, you can see some minor graphical glitches.

Text mode applications in Unix terminals are such a mess. It’s a miracle that this works at all.

In the old DOS days, you could get text (and colors) on the screen just by writing to memory, because the VGA memory was mapped to a fixed address. We don’t have that model anymore. To write a character to a certain position, you have to send an escape sequence to move the cursor to that position, then more escape sequences to set the color/attributes, then more escape sequences to get the cursor to where you actually want it. And then of course UTF-8 on top, i.e. you have no idea what the terminal will actually do when you send it a “🙂”.

Mouse events work by the terminal sending escape sequences to you (https://www.xfree86.org/current/ctlseqs.html#Mouse%20Tracking).

ncurses does an amazing job here. It’s fast (by having off-screen buffers and tracking changes, so it rarely has to actually send full screen updates to the terminal) and reliable and works across terminals. Without the terminfo database that keeps track of which terminal supports/requires which escape sequences, we’d be lost.

But gosh, what a mess this is under the hood … Makes you really miss memory mapped VGA and mouse drivers.

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.)

AI systems being egregiously resource intensive is not a side effect — it’s the point.

And someone commented on that with:

I’m fascinated by the take about the resource usage being an advantage to the AI bros.

They’ve created software that cannot (practically) be replicated as open source software / free software, because there is no community of people with sufficient hardware / data sets. It will inherently always be a centralized technology.

Fascinating and scary.
