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

Nun habe ich mir einen eigenen webbasierten TwtxtReader erstellt. PHP-basiert mit Phpfastcache, Fluid Template Engine und asynchronen cUrl-Requests für die abonierten Feeds. Inspiriert durch Timeline von @sorenpeter@darch.dk
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

"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?
@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:
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)
@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/
Merry Christmas everyone! Have a very low resolution sitting canine, to end this year with.
Bitcoin Reaches and Surpasses $100k USD
Bitcoin just broke $100,000 USD for the first time and reached as high as $104k, and is now sitting at $102,857 at the time of this writing.
Slashdot was pretty early on Bitcoin. Thoughts, nocoiners?

Time for the annual profile picture change. 😅
Second pixelart I drew this year, expecting my least active artist award soon! 💪🏆
I have just made yet another convoluted twtxt notifications script! Feeling like an old dog learning new tricks! 🤣
And they have arrived (well, they did around 3 hours ago, LOL). Buttery smooth, my 16 Pro (one with dark cover). It took a bit over an hour to transfer all my data.
Alright. My first mentions—which were picked not so randomly, LOL—are @prologic@twtxt.net, @lyse@lyse.isobeef.org, and @movq@www.uninformativ.de. I am also posting my first image too, which you see below. That’s my neighbourhood, in a “winter” day. Hopefully @prologic@twtxt.net will add my domain to his allowed list, so that the image (and any other further) renders.
Beginnings of a little notebook app. Doesn’t actually run any code yet. https://akkartik.name/images/20240917-notebook.png
@prologic@twtxt.net earlier you suggested extending hashes to 11 characters, but here’s an argument that they should be even longer than that.
Imagine I found this twt one day at https://example.com/twtxt.txt :
2024-09-14T22:00Z Useful backup command: rsync -a “$HOME” /mnt/backup
and I responded with “(#5dgoirqemeq) Thanks for the tip!”. Then I’ve endorsed the twt, but it could latter get changed to
2024-09-14T22:00Z Useful backup command: rm -rf /some_important_directory
which also has an 11-character base32 hash of 5dgoirqemeq. (I’m using the existing hashing method with https://example.com/twtxt.txt as the feed url, but I’m taking 11 characters instead of 7 from the end of the base32 encoding.)
That’s what I meant by “spoofing” in an earlier twt.
I don’t know if preventing this sort of attack should be a goal, but if it is, the number of bits in the hash should be at least two times log2(number of attempts we want to defend against), where the “two times” is because of the birthday paradox.
Side note: current hashes always end with “a” or “q”, which is a bit wasteful. Maybe we should take the first N characters of the base32 encoding instead of the last N.
Code I used for the above example: https://fossil.falsifian.org/misc/file?name=src/twt_collision/find_collision.c
I only needed to compute 43394987 hashes to find it.
