@movq@www.uninformativ.de Woah, that sun from satellite SDO is fucking sick! https://social.bund.de/system/media_attachments/files/113/859/065/836/106/300/original/95b43f7a0086476d.jpeg
Clouds are hiding the planets right now, but the sky was slightly on fire before: https://lyse.isobeef.org/abendhimmel-2025-01-20/
This UX can be very frustrating.
ISS (the long “line” on the right) passing Venus and Saturn:
Jupiter and its moons a few days ago:
Not spectacular shots, but hey, it’s something.
Also saw the crescent Venus and Saturn’s rings through my scope (you know, the one for bird watching).
The most valuable resource is Table B-13 at the end of Volume 2D of the Intel docs. It’s a very long but easy to understand table of instruction encodings – assuming you already know how that ModR/M stuff works.
@lyse@lyse.isobeef.org Yeah, what else does one need? 😅
I added more instructions, made it portable (so it runs on my own OS as well as Linux/DOS/whatever), and the assembler is now good enough to be used in the build process to compile the bootloader:
That is pretty cool. 😎
It’s still a “naive” assembler. There are zero optimizations and it can’t do macros (so I had to resort to using cpp). Since nothing is optimized, it uses longer opcodes than NASM and that makes the bootloader 11 bytes too large. 🥴 I avoided that for now by removing some cosmetic output from the bootloader.
Alright, I have a little 8086 assembler for my toy OS going now – or rather a proof-of-concept thereof. It only supports a tiny fraction of the instruction set. It was an interesting learning experience, but I don’t think trying to “complete” this program is worth my time.
The whole thing is just a learning project, I don’t want to actually make a usable OS. There are a few more things I want to have a look at and then I’ll eventually move on to 386/amd64 later this year (hopefully).
oh also out of boredom i hosted glance even though i have no need for a dashboard lol. it’s really cute though
@kat@yarn.girlonthemoon.xyz sticker status!!!!!
Noice!
I’m sharing new developments on the client. I now have a more stable timeline. The first version will appear in the next few weeks.
The editor can launch a new shell now:
https://movq.de/v/6ec68b50dd/los86-edit-shell.mp4
Trivial to implement but super useful. It allows for simple but meaningful dev cycles: Edit source code, run/test it, back to editor. That’s what I do in the video.
(The Brainfuck program is silly, but I got nothing else at the moment.)
The I/O cache is also getting better. All that back and forth doesn’t hit the disk at all, once cached.
This whole thing is much more fun and interesting when you run it from a real floppy disk. It’s a 5.25” floppy in the video (so it’s actually floppy 😅). Disk seek times can be catastrophic and you don’t notice any of this on modern disks.
This is the first screenshot, a simple timeline I’m using to check the fields. Now I’m working on some details: avatar cache, relative dates, simple thread, etc.
My OS has a Brainfuck interpreter now and this counts as a programming language, right? We’re feature complete now. 😂
An hour later and I have glued together a new batch of cardbord boxes. I’ve cut out the blanks several days ago, though. Easy upcycling project:
My shoulder muscles are sore from yesterday’s overhead concrete drilling. I even totalled a good drill bit. The workshop air cleaner is now installed on the ceiling. I even can plug in the shop vac directly above its usual location without having to walk over (or usually on) the cord on the ground. The shop vac hose crane had to be shortened 9cm in length in order to fit underneath the air cleaner.

@aelaraji@aelaraji.com Yeah, that sounds familiar. 😅😩 Reminds me of that comic: https://movq.de/v/1e2bcf790f/logout.jpg Stay strong 💪
Oh no, best wishes, @aelaraji@aelaraji.com! To hopefully brighten your day a tad:
@kat@yarn.girlonthemoon.xyz LOL 😂 Not that it’s a competition or anything… But here you go 🤣
Hey this could be good news for self-hosters and folks that want to run their own yarnd? 🤔 Vultr is offering 1 vCPU, 500MB Memory and 10GB Storage for FREE! That’s right $0.00 🤣
It’s nice to see that some Crawlers actaully respect rate limits and respect a 429 Too many requests response 👌 Thank you Google! 🙌
thanks to prologic i now know i can post video here. sorry for bringing idol fancams to this humble network do you still love me
testing video posts here’s a yunjin fancam
"twtxtfeevalidator/0.0.1" UA about? I thought I could ask before throwing a 1000GB file at it 🪤 could it be the same 'xt' thing @lyse was talking about the other day?
@lyse@lyse.isobeef.org yep, I gave it a spin locally! I freaking love the cute logo and the UI is fiiiine 👌 my TUI browsers love it just as much …

@aelaraji@aelaraji.com Ta! It’s just the millenia old tabs vs. spaces debate. ;-) Here’s a screenshot, that also kinda serves as a preview of the ugly – yet functional – web interface:
To quote GLaDOS: Yesterday I saw a deer!
The fact that the official Python docs don’t clearly state what a function returns, grinds my gears. This has cost me so much time over the years. You always have to read through a huge block of text.
You could at least put a list of possible return values in there (always at the same location, please!), here’s a mockup:
Noon in summer:
And noon in winter:
The difference never fails to make me go “whoa”. 😅
This evening, Saturn will show up right next to a crescent moon:
Let’s see if I can catch that in a photo.
Couldn’t find anybody to join me this arvo, so I went alone. Only in the forest I began to see real snow. And then of course with each meter of elevation gain. I reckon there were 5-6 cm at the summit, so there is still room for improvement. The weather was absolutely stunning, a sunny blue sky alternating with clouds, most of my hike hardly any wind and 1°C. Climbing the mountain was a different story, the wind hit me hard.
I just love the wind-brushed formations of ice on the twigs and branches. They look soooo incredibly cool. It was kinda hard to capture them on film with the wind pushing everything around.
On the way down I took the narrow and currently fairly slippery path that was closed for some weeks due to felling activity. It looks so different with heaps of trees on the ground now. They’ve also sawn down the tree with the small hole near the ground (which I think I’ve shown a few times in the past). The beech in 52 to 54 was probably hit by lightning a few months ago. At least it’s completely charred.

@kat@yarn.girlonthemoon.xyz Please do! :-) My brother made my penguin a Tux scarf one or the other decade ago when he was in probably elementary school: https://lyse.isobeef.org/tmp/tux-scarf.jpg
@bender@twtxt.net :-D Unfortunately, there is not much white fluffy stuff on the ground at all: https://lyse.isobeef.org/morgensonne-2025-01-03/01.jpg (And my brain is broken, I’d like to change it. I first called the directory “2024-05-03”. O_o)
Holy Smokes 🤣 And this has only been <24h 😱
@lyse@lyse.isobeef.org /me looks at Lyse’s direction, full of envy. 😂
Gesundes Neues, @arne@uplegger.eu! Was machst Du mit den Raketenstecken? Bastelst Du damit tolle Dinge? Ich hab damit zwei kleine Regälchen zusammengeleimt: https://lyse.isobeef.org/tmp/tischbohrmaschinenregal/10.jpg
Der Wind hat mir soeben einen neuen Stecken beschert, lag er doch plötzlich vor der Tür. Muss wohl vom Dach runtergekommen sein. Damit hab ich ganze zwei dieses Jahr. Hier wird sehr stark auf Böller gesetzt, ein absolutes Unding!
It was supposed to start raining this afternoon, but a rain cloud hit us in the morning just when we approached the foot of our backyard mountain. With the dark sky above us and wind speed picking up, we decided to take the next turn and head back. Luckily, the rain didn’t last long, so we paid the tadpole pond a visit to prolong our stroll. My mate told me that it was frozen a few days ago, but there was not much of the icy cover left today. https://lyse.isobeef.org/waldspaziergang-2025-01-02/
We had a faint yellow-orange-redish sky this evening. Only subtle, but it was actually one of those rare 360° sunsets. Just when I thought, that was it, it’s now over, the colors took off like crazy: https://lyse.isobeef.org/abendhimmel-2025-01-01/
A much nicer start into the year than all the hell yesterday. However, just as I type this, there come also the next round of explosions as darkness falls. Those bloody fuckers, please blow yourselves up!

Okay, this is pretty cool. My 8086 toy OS running on my old Pentium from an actual floppy disk. 😍 I just love that sound and the feeling of using floppies. This brings back so many memories from my early DOS days.
The cp-unopt program copies a file and intentionally uses small unaligned reads/writes (hopefully triggers more bugs).
The I/O cache works “okay-ish”, I guess. When sha1 runs, it has to do a few reads for the first file and basically none for the second one. Both could have been served entirely from the cache, theoretically. (But even just having an I/O cache in the first place speeds up things dramatically.)
Notice how there’s an EA file. That’s a left-over from OS/2, because I copied some files to the floppy using OS/2. In other words, my FAT12 implementation survives OS/2 writing to it. 🥳 (But I guess it should show up as EA DATA.SF. My current code starts at the left and stops at the first space.)

Made a little text editor for my 8086 toy operating system today. It can’t do much, but it allows for some basic editing. 💾
That was probably the last “big” thing I did for that OS in the near future. Vacation is coming to an end.
It’s getting Winter-y. Here’s that tree again: https://movq.de/v/07262a1e12/IMG_20241229_142030.jpg-small.jpg
That FAT12 implementation is very naive and unoptimized. You can see in this video that it takes about 7 seconds to copy a ~10 kB file: https://movq.de/v/fbf2b90ce1/los86-fat12-copy.mp4 🥴 I kind of like that, though, because it feels a little bit like an old machine. 😅🤪
After taking a short break for Christmas business, I’ve worked on my little toy operating system for the 8086 again.
It understands the basics of FAT12 now. I’ve actually never sat down before to learn how FAT works. 🤦 Well, better late than never, I guess.
It can’t do subdirectories nor timestamps and I probably won’t implement that. One flat directory is good enough for my purposes and the OS has no notion of time, yet, anyway.
It’s really cool to be able to exchange files with the Linux host or other DOS VMs. 🥳
3°C today, it was quite nice in the sun. A lot of hunting and tree felling going on in the forest. And we met the heron again, that was very cool: https://lyse.isobeef.org/waldspaziergang-2024-12-28/
And now some stupid fuckwits are burning firecrackers again. Very annoying. Can we please ban this shit once and forever!?
