What is Hackers' Pub?

Hackers' Pub is a place for software engineers to share their knowledge and experience with each other. It's also an ActivityPub-enabled social network, so you can follow your favorite hackers in the fediverse and get their latest posts in your feed.

in minecraft, you can smelt cobblestone to make stone, which i called "cooked stone" when i used to play it.

nowadays you can smelt stone again, which makes smooth stone.

what should this be called?

The repository is now public! codeberg.org/hkzlab/Flaccid_Os

The Flaccid Ostrich is a clone of , a floppy/smartport emulator for and computers.

Thanks to for having sponsored the PCBs for this project!

I recreated the schematics to repair my original unit, and while I was at it, I decided to build a clone using THT technology, just in case someone wants some DIY.

Have fun! If you like my work, feel free to throw a few credits to me via Ko-Fi (link in bio) ☕. I use them to buy components for the projects I work on and release for everyone to use.

They really, really help.

An assembled Flaccid Ostrich powered up. Seen from above, showing its dual floppy mode.

Picked up the PCIe NanoKVM.

Good: Worked right out of the box, cheap, gets powered from PC even when PC is off.
Bad: The internal cabling is pretty messy + poorly documented (specially the USB one).
Ugly: The OLED display is impossible to read, slightly misaligned and mostly pointless.

Might get another one or two if they come up for sale anytime. The Comet is better, but no purely internal version.

Picture from a friend.

There's some sort of Talos Principle Of Systems Administration in this world. Large model this, cloud that, doesn't matter: there's always going to be somebody in a server room, and they're always going to have diagonal cutters to hand, because that day's always coming. You are never far from the physical layer.

A picture of a fiber connection done very wrong.

When we look at the performance of QUIC, we often find that the limiting factor is CPU consumption of socket calls and crypto processing. It is, but congestion control also matters quite a big. In this blog (privateoctopus.com/2026/01/30/) I explain how fixing the "max RTT" measurement and the pacing algorithm for the C4 algorithm improved tests of picoquic on loopback from "worse than BBR" to "better than Cubic".

My Steam Deck has always had catastrophically slow SD card speeds. Now it's to the point where certain games (particularly Rocket League) are so slow to patch that even if I kick off a batch update at 9PM, by 11AM the following day the patching isn't done. There are directions suggesting that repartitioning might help (but then I'd need to redownload a terabyte of games). But *why*? I manually ran fstrim (which took an hour) and it sped up for a few minutes, then back to multi-minute stalls

If you like fox and wildlife photos, you want to take a look at this article, and then maybe follow @toomanyfoxesFoxes Every Hour (who linked me to this because Ray Hennessy is the generous source for some of their photos). The story makes the pictures even more interesting than they already were.

It's really heartbreaking to see a technically superior OS (MacOS/iOS) turn into complete dogshit because the people running the show are clueless.

They had the best implementations of almost everything but decided to just keep making the user experience worse every release and letting the craziest bugs manifest and go unaddressed for years

I guess with Cook being so focused on making Apple a services-focused company it was bound to happen, but damn... they really ruined a technical masterpiece.

And worse, every release they make it even harder for a competent engineer to actually debug these kind of issues. What good is having Dtrace if you can't even use it because of SIP, etc?
