FUSE supports io_uring, very cool.

I know there is some overhead to using FUSE that makes it less than ideal for proper filesystem use cases, but I would assume something like io_uring closes the gap of performance a bit due to its design.

I saw this on QEMU’s Google Summer of Code 2025 asks, in which they’re looking for someone to “Extend QEMU’s FUSE export type with FUSE-over-io_uring support”, very cool.

Deel’s Alleged Spy Locked Himself in Bathroom When Confronted by Court-Appointed Solicitors Friday

“I’m Willing to Take that Risk [of Violating the Court Order]” Alleged Deel Spy Declared When Served with Legal Papers to Hand Over His Phone

The words “Corporate Espionage” are not used lightly here, this is some movie level nonsense.

According to the lawsuit, Deel’s spy spent over four months obsessively and systematically accessing Slack channels where he had no legitimate business interest. He searched Slack more than 6,000 times – allegedly swiping confidential sales pipeline data and internal customer interactions.

The ‘spy’ was a Slack-a-holic, nice.

#include <stdio.h>

int main () {
  const char* s = "this is not going to appear because it's going to be reassigned";
 defer printf(" bark!\"");
  defer printf("%s", s);
  defer {
  	defer printf(" woof");
  	printf(" says");
  }
  printf("\"dog");
  s = " woof";
  return 0;
}

The output of this program is as follows:

$> ./a.out
"dog says woof woof bark!"

Looks like C might be getting the defer keyword, sick!

6502.sh is a fully-functional 6502 emulator and debugger written in busybox ash compliant shell script, using only a handful of busybox tools.

Features

6502.sh has a whopping 32k of RAM and 16k ROM in its default configuration, however this can be easily adjusted by editing machine.sh.

It includes an interactive debugger with single-stepping, breakpoints (break on code, data access, JSR/RTS), and more. See #Debugger for detailed instructions.

Saw this on Mastodon, very cursed, but very amazing.

My favorite family tree.

Very cool Quake source port that’s basically at this point its own game engine.

I managed to get it building on Mac! Doesn’t look like finding Mac binaries of this is super trivial, I might host them on this site somewhere.
