In-reply-to » PSA: setpriv on Linux supports Landlock.

@movq@www.uninformativ.de That’s really cool! I wanted to experiment with Landlock in tt as well. But other than just thinking about it, nothing really happened.

Depending on the available Landlock ABI version your kernel supports, you might even restrict connect(…) calls to ports 80, 443 and maybe whatever else has been configured in the subscription list.

I didn’t manage to leave the house yesterday. But when I went into the woods this evening, activity first was 10% of what it had been the day before yesterday. By the end it got a lot busier, about 50% of last time I reckon. Around 500 fireflies I’d imagine. I might have been faster than the days before. When I left the forest, I was right in the fog, that was cool.

Shortly after, I saw another lightshow. Right behind the Wasserberghaus somewhere on the Swabian Alp there was very crazy heat lightning every 5-10 seconds. That looked absolutely amazing. :-)

I did a “lecture”/“workshop” about this at work today. 16-bit DOS, real mode. 💾 Pretty cool and the audience (devs and sysadmins) seemed quite interested. 🥳

  • People used the Intel docs to figure out the instruction encodings.
  • Then they wrote a little DOS program that exits with a return code and they used uhex in DOSBox to do that. Yes, we wrote a COM file manually, no Assembler involved. (Many of them had never used DOS before.)
  • DEBUG from FreeDOS was used to single-step through the program, showing what it does.
  • This gets tedious rather quickly, so we switched to SVED from SvarDOS for writing the rest of the program in Assembly language. nasm worked great for us.
  • At the end, we switched to BIOS calls instead of DOS syscalls to demonstrate that the same binary COM file works on another OS. Also a good opportunity to talk about bootloaders a little bit.
  • (I think they even understood the basics of segmentation in the end.)

The 8086 / 16-bit real-mode DOS is a great platform to explain a lot of the fundamentals without having to deal with OS semantics or executable file formats.

Now that was a lot of fun. 🥳 It’s very rare that we do something like this, sadly. I love doing this kind of low-level stuff.

In-reply-to » @kat I was about to say that you can always just buy one, but apparently that’s not so easy anymore?! What the heck happened? 🤨 There used to be several shops here in Germany that sold a variety of Tux plushies, but none of that exists anymore … 😳

@lyse@lyse.isobeef.org @kat@yarn.girlonthemoon.xyz There are two more shops that sell the “classic” Tuxes: https://ixsoft.de and https://www.steiner-plueschshop.de – both German shops, though. 🥴 Anyway, if you can make one yourself, that’d be extra cool. 😃

In-reply-to » i started a little thing on my dreamwidth and called it a flash prompt box. basically it's a limited time thing where people can prompt me for stuff i'm offering, like short fanfiction, photoshop-edited user icons, music recs, and a bit more! i'm having sooo much fun with it so far it's been a blast just making stuff for friends :)

@kat@yarn.girlonthemoon.xyz This sounds cool! 😎 Can you show me? 🤔

In-reply-to » @xuu or @kat Do either of you have time this weekend to test upgrading your pod to the new cacher branch? 🤔 It is recommended you take a full backup of you pod beforehand, just in case. Keen to get this branch merged and to cut a new release finally after >2 years 🤣

@kat@yarn.girlonthemoon.xyz Yes see UPGRADE.md – I believe @xuu@txt.sour.is is now running this live after a couple of hiccups and a bug fix. So yeah if you can, that would be cool, basically looking for early beta testers (I was the alpha tester 🤣)

In-reply-to » Btw @andros ; The automated feed you put together for Hacker News... Does it at any point rewrite parts of the feed as it goes along? 🤔 I've had to unfollow it because I've found in practise it makes a twt, then seems to modify that same twt (observed by content manually) at least twice. This ends up becoming effectively an "Edit" and essentially duplicate (looking) posts 😢

@andros@twtxt.andros.dev Ahh cool! I’ll try following it again 🤣 Mind @-mentioning/linking@twtxt.net the feed again? 🙏

oh out of boredom yesterday i made my blog available via markdown files too so you can use charmbracelet/glow to read them in your terminal :)

basically i just set up a file directory on a path of my blog, organized the MD files by year, and so in theory you can navigate to that path and choose a folder, then copy a link to a markdown post and run this:

glow -p https://bubblegum.girlonthemoon.xyz/md/2025/2025-03-31%20premature%20reflections%20on%20sudden%20responsibility.md

and then as long as you have glow installed, you can read my posts from the terminal :D it’s so cool

i could do anything for wonyoung but nothing will ever be as cool and iconic as the 13 year old daughter of the baidu vice president who doxxed over 100 people during an argument for hating on wonyoung. Absolute icon

WinRing0: why Windows is flagging your PC monitoring and fan control apps as a threat
When I checked where Windows Defender had actually detected the threat, it was in the Fan Control app I use to intelligently cool my PC. Windows Defender had broken it, and that’s why my fans were running amok. For others, the threat was detected in Razer Synapse, SteelSeries Engine, OpenRGB, Libre Hardware Monitor, CapFrameX, MSI Afterburner, OmenMon, FanCtrl, Z … ⌘ Read more

NES86: x86 emulation on the NES
The goal of this project is to emulate an Intel 8086 processor and supporting PC hardware well enough to run the Embeddable Linux Kernel Subset (ELKS), including a shell and utilities. It should be possible to run other x86 software as long as it doesn’t require more than a simple serial terminal. ↫ NES86 GitHub page Is this useful in any meaningful sense? No. Will this change the word? No. Does it have any other purpose than just being fun and cool? Nope. None of that … ⌘ Read more

9front “THIS TIME DEFINITELY” released
The operating system I’m not cool enough to run has pushed out a new release: 9front “THIS TIME DEFINITELY” is now available. 9front is a fork of plan9, created after plan9 languished at Bell Labs. This release enables gefs, the new file system, in the installer, “ip/ipconfig now support dhcpv6 dynamic allocations and handles prefix expirations”, and it comes with some smaller changes, too, of course. Despite every piece of evidence to the contrary, I am s … ⌘ Read more
