Had no clue @prologic@twtxt.net has his own computer mouse brand now, straight up giving them away, for under $3 a piece.

I got one and well pleasantly surprised, especially for the price. It fits perfectly in the hand, decent rubber, weighs nothing, clicks very silently. The scroll wheel is where you can feel some of the cost cutting, it’s pretty wonky, but good enough.

Classic cheap thin long cable, you better like 1600 DPI, cause there’s no button to change that. Sensor is the usual red light, but works on all surfaces, bedsheets included. Gliders are small and not around the sensor, but at this weight, that makes next to no difference.

Decent 8/10 option

At 8 o’clock, we had chilly 10°C. My mate and I dashed up our backyard mountain in just a tad under an hour. And that wasn’t the direct way. Our jumpers came off quick. It was really nice, because the sun was already warming and lighting up the landscape and everbody else still asleep. We had everything to our own.

Shortly after we were atop, the first two yoga women showed up with their mats. When we decended, a bunch more were on the way up. And then came the families with dogs and kids. Very glad to have missed all this hustle and bustle.

Now, I’m really tired. But it’s a great feeling of exhaustion. Two and a half hours later, we’re at 17°C. It’s supposed to hit an acceptable 23°C later on.

Unfortunately, no pics. I learned that charging via the docking station when the computer is turned off doesn’t do shit at all. Oh well.

It is such a nice feeling that Mu is such a capable little language 😅 And I decided to write code code in Mu by hand 🤚 haha 🤣 and start solving Project Euler problems, like Problem 8 which works out to be a nice elegant solution in Mu:

#!/usr/bin/env mu

// Largest Product in a Series

import "fp"
import "sys"

fn usage() {
  print("Usage: cat |", args()[0], "<n>")
}

fn products(xs) {
  return fp.reduce(xs, 1, fn(x, y) {
    if y == nil {
      return x
    }
    return x * y
  })
}

fn main() {
  if len(args()) < 2 {
    usage()
    exit(1)
  }

  s := must(sys.read_all(0))
  if len(s) == 0 {
    usage()
    exit(1)
  }

  n := must(int(args()[1]))
  r := fp.max(fp.map(fp.sliding(fp.map(s, int), n), products))
  print(r)
}

main()

So… my little experimental Mu (µ) OS is now ~8.7k of Mu and ~2k of Assembly, which makes this about an ~80/20 split. I’ve managed to achieve most of the goals I had set out, by ensuring a tiny Nucleus of only ~2k Assembly and all Policy, Services and Userland written entirely in Mu (a language I also deisnged and created, which still has no support for floats LOL)

↳ In-reply-to » I trip over this in our code at work all the time.

@movq@www.uninformativ.de The nice thing about properties is that you can compute and cache things on the fly at first attempt and also ensure validation for writing. But like you said, since it’s not obvious that reading or writing might do some more things, it’s strongly advised to avoid doing expensive stuff disguised as properties.

I reckon the vast majority of property use cases is to provide read-only access. At least that was my impression when I was doing a lot more in Python.

Personally, I think that this just reads a lot nicer:

oink.my_property
oink.my_property = 42

Than:

oink.get_my_property()
oink.set_my_property(42)

Btw, any field access is implemented using method calls. I might be wrong, but I believe there’s always __getattr__ and __setattr__ involved. 8-)

@david@daiwei.me Oh, really? I thought I’ve posted compose view screenshots before. Anyway. Glad you like it as much as I do. :-)

The update interval has always been one second. I just didn’t remember and thus tried to time it by watching the preview update while typing. It felt like roughly under two seconds, but apparently my inner clock was off. After taking the screenshot and then examining it more closely, I noticed that the interval is stated right in the UI. :-D So, I just amended my message and didn’t bother taking a new screenshot. I figured I just leave it alone and see who spots the change, if at all. And, of course, you found the easter egg. Congrats, mate! 8-)

@GabesArcade@gabesarcade.com The no-JS part is one thing, but you also have to disable the (nowadays common) forced-HTTP-to-HTTPS-redirect, because those old browsers can’t do modern crypto. And make sure that your webserver serves the correct page even if no Host header is sent by the client. And don’t even think about serving UTF-8 or even just putting utf-8 in the content type. 😅 And for the JPEG thumbnails I pass a special flag to ImageMagick so that IBM Web Explorer from OS/2 won’t trip. 🤣 And always use link rel="stylesheet" for CSS, because some browsers render inlined CSS as literal text. And … probably more that I forgot by now. 😂

Every now and then, I think that I have carefully proof-read my message enough times and hit the “Add message” button in tt. But then, in the message tree, I spot another missed typo. My process is then to go to my twtxt.txt and fix it by hand. However, I still have to clean up tt’s cache. This is rather tidious:

  1. Recall the sqlitebrowser ~/.local/share/twtxt/tt2.sqlite from my shell history.
  2. Switch to the “Browse data” tab.
  3. Go to the messages table and wait a second or two until it’s loaded.
  4. Sort by the created_at column twice, so that I get descending order.
  5. Select the first message, which is typically the one in question.
  6. Find the “Remove currently selected row” button in the tool bar.
  7. Commit the changes.
  8. Close sqlitebrowser.

So, I finally implemented the removal of messages from the cache in tt. I can now hit d and confirm the removal. Bam! Should have done that ages ago!

Next up is the search, I think.

↳ 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 » @lyse (Do you want to be linked on that page? Do you want your name to be there at all? 🤔)

@movq@www.uninformativ.de I really like your style of writing, btw. It’s much calmer and less aggressive then mine. :-) When I turned my bullet points into paragraphs, I got a bit mad in the process.

Sure, feel free to include anything you want. Regarding citing, this is where twtxt falls short in my opinion. Especially with feed rotation, classic links die quickly. Message hashes only help so much. Nobody outside the twtxt universe knows how to deal with them. So, not perfect for inclusion on a web page. Linking to a thread or message on some yarnd instance might be the more user-friendly option. But the disadvantage is that it’s “just” a mirror, not the primary or original source. In all reality, this could be considered splitting hairs, though.

I should have probably written a proper article. That would have given me time to review the result more carefully, too. ;-) Perhaps that’s something for the future. But honestly, I’m not sure if I really want to waste my time and energy on that subject. So many other fun or useless things come to mind right away that I could do instead. 8-)

So, yeah, do whatever feels best to you. I don’t mind being cited or linked, but I also don’t mind not to be cited or not to be linked to. :-D Not a helpful answer, I know. Sorry. ;-) But anyway, thanks for asking, mate! I do appreciate it.

To finish my thought, linking to my frontpage is probably also useless, since I deliberatly do not have a table of contents there. In fact, my entire frontpage is rather silly.

@lyse@lyse.isobeef.org Oops, I guess the new text is a bit obscure. If you follow the link, the text is a bit more explicit, but you still need to know what a lexical scope is. Anyway, this is part of Perl moving very carefully toward being UTF-8 by default while also not breaking code written in the 90s. If you name a recent version like “use v5.42;” then Perl stops letting you use non-ASCII characters unless you also say “use utf8;”. The “lexically” part basically means that strictness continues until the next “}”, or the end of the program. That lets you fix up old code one block at a time, if you aren’t ready to apply the new strictness to a whole file at once.

Another project where I’m going to use my terminal widget toolkit is a hex editor. This is still very young, obviously, and there’s a lot of work to do (both in the toolkit and this particular application), but I’m making some progress:

https://movq.de/v/2bae14ed16/vid-1769283187.mp4

Since this program is UTF-8 clean (I hope), you can do things like enter multi-byte UTF-8 sequences or paste them from the system clipboard (another hex editor I just tried failed to do this correctly):

https://movq.de/v/e9241034c1/vid-1769283755.mp4

Under the hood, I’m using mmap() with MAP_PRIVATE, which is really cool: I get the entire file as a byte array, no matter how large it is, no need to actually read it upfront; and MAP_PRIVATE means that I can write to this area however I like without changing the underlying file. The kernel does copy-on-write for me. Only when you hit Save, it will write to the filesystem. And it’s just a couple lines of code. The kernel does all the magic. 🥳

↳ 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.
