(#5drlumq) @lyse@lyse.isobeef.org Oof, I know that feeling. 😂 (It was much worse when I still had my 1280x1024 screen. 🥴)

Corporate IT environments are just a nightmare. Bah. No. We don’t talk about that now. It’s the weekend! 🥳🥳🥳

Friendly, regular reminder to always check if a TV show has already been cancelled before you start watching it.

(#oa6ubuq) @andros@twtxt.andros.dev Nope, unfortunately not. I took a look at Lisp last year (I think I used sbcl), but I haven’t done anything really useful with it. I still want to give it a proper go some time in the future. I do like how flexible it can be. Rather simple, but powerful basic concepts.

What’s your favorite dialect?

(#lotmkpa) @kat@yarn.girlonthemoon.xyz I approve! That’s how I learned HTML (version 4 at the time and XHTML shortly after) and making websites, too. Some of them are still made like this to this day. Hand-written HTML. Hardly any <div> and class nonsense. I can’t remember with which editor I started out with, but I upgraded to Webweaver (later renamed to Webcraft) quickly. Yeah, this were the times when there was just a single computer for the whole family.

Free hosting on Arcor, Freenet and I don’t know anymore how they were all called. Like this author, I uploaded everything via FTP. Oh dear, when was the last time I used that? And I had registered plenty of free .de.vu domains.

Being on Windows at the time, everything was ISO-8859-1 for me. No UTF-8, I don’t think I’ve heard about it back then.

Later, I wrote my own CMSes in PHP. Man, were they bad in retrospect. :-D Of course, MySQL databases were used as backends. I still exactly know the moment I read the first time about SQL injections. I tried it on my own CMS login and was shocked when I could just break in. The very next thing I did was to lock down everything with an .htaccess until I actually fixed my broken PHP code. Hahaha, good memories.

I swear by Atom or RSS feeds. Many of my sites offer them. I daily consume feeds, they’re just great.

Does anyone here write in a Lisp dialect? #clojure #commonlisp #lisp

(#liaoqeq) @kat@yarn.girlonthemoon.xyz True! :-D

(#5drlumq) @movq@www.uninformativ.de Yes, exactly that. It’s awful! And it’s getting worse from my perspective. Nobody in charge is ever gonna learn anything. I figure we just fully deserve this M$ crap, every single bit. :-(

Luckily, the most important development platform still worked for me, so I could actually do something, review code, pull and push, etc. But the calls with the screenshares were nightmares. Can’t see shit on such a tiny display with today’s extreme monitor sizes people use. Looking at logs, hahahahahahaaa…

(#pby67wa) @movq@www.uninformativ.de Neat, that sounds like a clever design with a table implementation. :-)

Oh, for sure! Complexity will definitely go through the roof and beyond with optimizations, no doubt. Maybe with the very simplest of the easy ones it might be still reasonably straight forward, but I also imagine that this has the potential to escalate very quickly. :-D

(#easggwq) (Uff, wow, ich glaube, das letzte Mal im Kino war ich 2003 zu „Matrix Reloaded“.)

(#6klltwa) @anth@a.9srv.net I stopped using a persistent browser profile ~10 years ago and this was a great decision. When I shut down my PC at the end of the day, the browser profile with all the tabs and history is gone. I don’t miss it at all. By now, I’m disciplined enough to take a note of important links right away.

This probably doesn’t work for everybody, but I love it.

(#5drlumq) @lyse@lyse.isobeef.org I take it this is a typical corporate network with a ton of firewalling rules? And, oh god, so much Microsoft. 🤢

(#pby67wa) @lyse@lyse.isobeef.org Heh, thanks, yeah, reading the Intel docs takes time. I’ve been doing that on and off since September (for this blog post), so I’m almost used to it now. But doing that for the very first time is quite gnarly. They’re not super well written.

I really think (this time) that I won’t add many more features. 😅 At the moment, the program is very “generic” and basically only does some pattern matching: If it sees a mov instruction followed by some 8 bit register and then some 8 bit number, then it encodes it as a 0xB0 byte using a certain mechanism (e.g., the register number might get added to 0xB0 and then the 8 bit number might just follow verbatim). That’s what the long list in the screenshot shows. “A cmp followed by two arguments of a certain type gets encoded as …” They’re all handled exactly the same.

Adding support for more instructions mostly just means adding more entries to that table.

If I were to add “optimizations”, I guess complexity would skyrocket. 😅

Another infrastructure apocalypse day at work. Linux and Windows users were unable to reach M$ services. No Outlook, no Teams, no intranet (Sharepoint), no Azure, etc. Mac users were lucky, though. Took whoever the whole day to resolve that. Shortly before I called it quits, it worked again. I haven’t read any e-mail today, used Teams mostly on the company phone, but it’s the plague.

And as I’ve forseen the other day, we have to deliver yet another workaround hotfix, once the other team eventually gets their stuff integrated that we should rely on. Good riddance it’s the weekend now!

(#pby67wa) @movq@www.uninformativ.de Oh, this is really awesome! :-) Hats off to you, that would take me forever to accomplish.

Haha, eleven bytes, how mean is that!? :-D But I already see you working on that as well at some point in the near future. :-)

(#3lby6ja) @prologic@twtxt.net Totally fine with me, I don’t use it. I just have to when hacking on yarnd, because it phones this service.

(#q6scuoa) @doesnm@doesnm.p.psf.lt Hmmm yhe flow doesn’t look right to me hmm 🤔

(#3lby6ja) @doesnm@doesnm.p.psf.lt Is that implementing IndieAuth? 🤔

(#3lby6ja) @bender@twtxt.net Aye aye 🙌

(#ot56hla) Sounds about as complex as adding @nick@domain support by doing a webfinger lookup to get the URL.

Would anyone object to the feeds.twtxt.net service having auth soon™ ? 🤔 I’m tired of the garbage feeds that it has accumulated over tie (spammers) and I want to a) clean it up b) lock it down somewhat.

The idea would be that you’d login with your Yarn.social account on some pod you control/operate or share with a nice person 🤣 – For those unfamiliar, this is called IndieAuth or IndieLogin. ALL Yarn.social pods are in fact valid (have been for years now) IndieAuth Providers. So I can just ust that. This also technically means you could login with your own domain too (more on that later…)

(#f4zop7a) @hacker-news-newest@feeds.twtxt.net TL;DR:

The author recounts their experience with a “no calls” policy in enterprise sales, finding it surprisingly effective. They attribute this success to addressing common reasons for calls—lack of understanding, onboarding issues, pricing uncertainty, and trust concerns—through clear messaging, self-serve onboarding, transparent pricing, and robust security documentation. While acknowledging potential limitations, the author advocates for a #nocalls approach, emphasizing the benefits of efficiency and alignment with their values.

(#y67iq2q) @lyse@lyse.isobeef.org Who does right 🤣 I wonder if anyone read the ToC(s) of any Yarn pod? 🤔

(#dpfx5la) @news-minimalist@feeds.twtxt.net Ahh now I like to read news like this in my feed. THis is perfect! 🤩 Thank you @bender@twtxt.net and so far this is such a nice quite way to be “informed” without the noise and sensational crappy clickbait shit™

(#zyk2tca) @kat@yarn.girlonthemoon.xyz Have fun. 🐧🚗 I played that a lot out of boredom during the peak of the pandemic. 😅

(#liaoqeq) @kat@yarn.girlonthemoon.xyz Well, consider me jealous. 😅

So, is that a standard lubuntu or a special version for that laptop? Any driver issues so far?

(#pby67wa) 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.

(#liaoqeq) @kat@yarn.girlonthemoon.xyz AKB48 and other spinoffs sound so great. I’m listening and whistling to them for hours now. I have no clue what the lyrics are about, but it’s just fantastic music. Thanks for introducing me to them. <3

(#pby67wa) @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.

(#zyk2tca) @kat@yarn.girlonthemoon.xyz Wrrrrrmmmmm, wrrrrmmm, have fun! I think I played that about 15 years ago last time or so. I never was much of a gamer, always loved to code useless stuff instead. :-D

(#liaoqeq) @kat@yarn.girlonthemoon.xyz Thanks!

(#y67iq2q) @prologic@twtxt.net Those people don’t read tocs.

(#b7gxewq) @kat@yarn.girlonthemoon.xyz Evening 👋

(#y67iq2q) @arne@uplegger.eu True! 👌👌

(#h5hud5a) @kat@yarn.girlonthemoon.xyz I also happen to use it to run https://mbox.blue as well as to front SSh access to https://git.mills.io 👌

(#y67iq2q) @arne@uplegger.eu To be honest I don’t really understand why anyone would use Facebook™, X/Twitter™, TikTok™ Instagram™, etc… When it clearly states in their Terms of Conditions that the content you “enter” into their systems, is NOT yours.

(#h5hud5a) @kat@yarn.girlonthemoon.xyz That was https://git.mills.io/prologic/sshbox

(#h5hud5a) @aelaraji@aelaraji.com Fuck sorry!

I’m refactoring (mangling four lines of of code with assignments into one function call) and man, do I love vim macros! Such a bloody amazing invention. Saves me heaps of manual labor.

(#5wwgfxq) Specifically those around 2:50min, 6:15min, 11:00min, 28:40min and 33:40min. :-)

(#liaoqeq) @kat@yarn.girlonthemoon.xyz Cool, cool, congrats! I skipped around and noticed that you used some great background music. Do you have a list for me to look up? :-) Also, that’s a nice desktop wallpaper in the end.

(#pby67wa) @movq@www.uninformativ.de Woohoo! You selected a turing complete instruction set, so all good. ;-)

(#oubbkhq) @suitechic@yarn.girlonthemoon.xyz It’s the exact opposite for me. :-)

(#2on5cpa) @bender@twtxt.net I always schedule the next appointment right away. :-) Yeah, over here, it’s just winter. Nothing really surprising. But it gets us every time. I prefer the ice over the the fire for sure.

@movq@www.uninformativ.de That was the only time I left the house today.

(#2on5cpa) @lyse@lyse.isobeef.org I read it in the news, lots of ice in your area. 🫤 (There’s nothing going on over here.)

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).

(#sgdea6a) @arne@uplegger.eu Haha nice one 😆

(#nm5tj6a) @andros@twtxt.andros.dev Created. Can you try logging in via Github? I had to take a stab/guess at your Email address, which is very clearly wrong, but hopefully you an just update it when you login 🤣🤣

(#nm5tj6a) @prologic@twtxt.net My account is @tanrax . Thanks!

(#nm5tj6a) Actually. it’s probably fine if you just drop your Github username/profile here. They’re all public info anyway 🤣🤣

(#nm5tj6a) @andros@twtxt.andros.dev I believe I disabled new registrations by default due to increase in levels of “spam accounts”. If you could email me, or DM me (IRC) your Github username, I’ll add an account for you that matches your Github profile and you can sign-in that way.

Respectfully, I will not move any of my projects back to Github after this blog post; hope you can understand, but I’d prefer to stick to my moral values here as much as I can 😅
