In-reply-to » I’ve been making a little toy operating system for the 8086 in the last few days. Now that was a lot of fun!

@mckinley@twtxt.net

So, just a hobby. It won’t be big and professional like GNU, then?

Ha! 😅 No, that certainly won’t happen this time. 🥴

(What an exciting time that was when there were new operating systems. 🤔)

Improving the filesystem is probably going to be the next big task. I don’t know that much about this stuff, so I’ll have to learn a lot. 🥴

I’ve been making a little toy operating system for the 8086 in the last few days. Now that was a lot of fun!

I don’t plan on making that code public. This is purely a learning project for myself. I think going for real-mode 8086 + BIOS is a good idea as a first step. I am well aware that this isn’t going anywhere – but now I’ve gained some experience and learned a ton of stuff, so maybe 32 bit or even 64 bit mode might be doable in the future? We’ll see.

It provides a syscall interface, can launch processes, read/write files (in a very simple filesystem).

Here’s a video where I run it natively on my old Dell Inspiron 6400 laptop (and Warp 3 later in the video, because why not):

(Sorry for the skewed video. It’s a glossy display and super hard to film this.)

It starts with the laptop’s boot menu and then boots into the kernel and launches a shell as PID 1. From there, I can launch other processes (anything I enter is a new process, except for the exit at the end) and they return the shell afterwards.

And a screenshot running in QEMU:

In-reply-to » QOTD: Do you have a way to get back into your home network if you get locked out?

@mckinley@twtxt.net

Early on, I was thinking about WAN IP address changes as well but it hasn’t happened in ~2.5 years with this ISP.

You mean to say you have the same public IP all the time? For 2.5 years now? Without paying extra? 🤔

In-reply-to » QOTD: Do you have a way to get back into your home network if you get locked out?

@mckinley@twtxt.net I used to have an SSH port reachable from the outside, but since I’m doing 99.999999% working-from-home now, I no longer need that. (I don’t even have a desk at the office anymore and – and this is important for us Germans! – no parking spot, either! 😅)

In-reply-to » A blog post of mine is on the front page of HackerNews again. Not sure if I like this. 🤔 Let’s hope there won’t be people shouting at me this time. Angry nerds can get quite emotional …

@prologic@twtxt.net Crap! 🤣

It’s unfortunate that so many people in tech have such an unfriendly communication style. I won’t read comments on HackerNews, for example. It’s sad, because these people might be more knowledgeable and they might have important things to add, but I just don’t like “being shouted at”. 🫤

In-reply-to » I was today years old when I learned that Firefox supports custom per-domain CSS. Is this new? I thought I had tried a while ago and it only worked globally. 🤔

@sorenpeter@darch.dk In your profile folder (somewhere under ~/.mozilla on Linux), there’s a chrome folder. You can put a file called userContent.css in there.

This also needs the setting toolkit.legacyUserProfileCustomizations.stylesheets to be true.

(I hope they never remove this, it’s super helpful.)

I was today years old when I learned that Firefox supports custom per-domain CSS. Is this new? I thought I had tried a while ago and it only worked globally. 🤔

@-moz-document domain(movq.de)
{
    div { border: 1px solid red; }
}

Either way, I love that I don’t need a plugin for that. 🥳

In-reply-to » Trying to get some custom T-shirts made. Ordered my first one with Media -- Let's see what eh quality of the print and T-shirt is before I make any more 😅

@prologic@twtxt.net Nice, let’s hope this works out! 🔥🐶🔥 I’ve been wanting to do that, too. Better wait until after Christmas, postal service is jammed now. 😂 (Not really, but I don’t want to add to the congestion.)

In-reply-to » Goodbye Blender, I guess? 🤔

@lyse@lyse.isobeef.org Mostly small and simple stuff, like cable management, headphone rests, pill dispensers (that I didn’t end up using), … The most elaborate thing I made was that contraption for my keyboard, which is a bit hard to explain right now, so here’s some photos:

I didn’t end up using that, either. 🥴

In general, I print very little. So little that some of my supplies have simply gone bad, like that “3D LAC” (sprayable glue).

@aelaraji@aelaraji.com Yeah, I saw that when googling the issue. I’m on Linux, there are no DLLs to swap. I could use an older version indeed. 🤔 Let’s see if I can find some better alternative first. (Let’s face it, Blender is hard to use.)

“A graphics card and driver with support for OpenGL 4.3 or higher is required. Installing the latest driver for your graphics card might resolve the issue.”

A bit annoying, but not much of a problem. The only thing I did with Blender was make some very simple 3D-printable objects.

I’ll have a look at the alternatives out there. Worst case is I go back to Art of Illusion, which I used heavily ~15 years ago.

In-reply-to » Imagine if all computer UIs would act like the UI from my NAS system... I feel I need to be waiting for output from the machine like it's 1973.

@lyse@lyse.isobeef.org The worst thing is, you never really know when it’s finished. If this showed a blank window for 5 seconds, it would still be annoying, but you wouldn’t start reading/scrolling the page, only for it to jump around like crazy, making you miss click targets, … It’s just horrible. 😂

I learned numbers today.

$ printf '\xC2\xB9, \xC2\xBC, \xD9\xA4, \xE1\xAA\x96, \xE3\x8D\xA4, \xDB\xB0, \xE2\x9D\xBB, \xE2\x91\xB9, 1' | grep -o '[0-9]'
¹
¼
٤
᪖
㍤
۰
❻
⑹
1

Sad that it doesn’t match on .

Confused by:

$ printf '\xE2\x9D\xBB, \xE2\x91\xB9, 1' | grep -o '[1-6]'
1
$ printf '\xE2\x9D\xBB, \xE2\x91\xB9, 1' | grep -o '[1-7]'
❻
⑹
1

So and are a 7?

Still haven’t dug up why it needs the extra ASCII 1 for anything to match. Maybe tomorrow.

@johanbove@johanbove.info … all UIs I have to use at work act like that. No, they are actually worse, because they behave like this: https://hiccupfx.telnet.asia/

I only get to enjoy fast and snappy UIs in my free time when I’m doing hobby stuff. You’d expect it to be the other way around. 🙄

So, AI cheaters have ruined the global Advent of Code leaderboard:

https://old.reddit.com/r/adventofcode/comments/1h9cub8/discussion_on_llm_cheaters/

And they don’t even try to hide it anymore.

At this point, any kind of speed contest or ranking has become meaningless. Seeing this kind of behavior is sad and probably unavoidable, because there will always be a few who spoil things for everyone.

The only way going forward, I can think of, is to remove the global ranking and just have private leaderboards. Basically what these two people have said:

Cheaters won’t get public attention anymore. AoC won’t be “officially” ruined by cheaters anymore. If you want to do a speed contest, you can still do that in private leaderboards.

(Honestly, I’d prefer it if AoC didn’t have any kind of ranking anyway. I’m not really fast enough to compete, but it’s always at the back of my head. And last year I made rank 116 once, so it’s not completely impossible. All this creates a lot of pressure that I have to fight and try to ignore. 🤣)

“A minimalist social network powered by plain text files”

My brain keeps shortening this to “a socialist network …” and then jumps to “uhh, large parts of the US won’t like this” … 🤦🤪
