I just got reminded that when you start a brand new smartphone the default screen autolock time is around 30s.

This is the attention span vendors are expecting from you.

Today I saw this UNIX v4 PDP11 emulator (running simh in the browser) and decided to write an IO plugin for radare2 to load tapes. Here's the source in case you are curious about how tapes are structured and how to extend r2 with new features like IO backends. https://github.com/radareorg/radare2/commit/aeeccc1d23d3b75edcd6e0013f1372830a6af134

@pancake Sounds like an oxymoron?

LMAO.

To prevent unexpected untrusted code execution, the Visual Studio Code Go extension is now disabled in Restricted Mode.

@wirepair Back in the day we were looking for E.T. or large primes on idle time, now we run ads.

@imreFitos Yes, this is what I observed before. Now the slight difference is that I know exactly when I closed YT and it was before the last video shown.

Checking my YT history, there are videos again I never even clicked, but I guess this is an easy way to rip off advertisers a bit more.

Glitches in games, especially used for speedrunning, are one of the most fun aspects of hacking to watch!

As an example, check out this video "How Speedrunners BEAT Hollow Knight Silksong In 10 Minutes!" by Abyssoft

Graphcore basically slapped a bit of SRAM onto every core, *inside* the processor tile.

GPU memory (VRAM) is super far away by comparison.

The ~2,400 cores on the Graphcore C2 could all run independent tasks without waiting in batches (aka, MIMD instead of SIMT).

The “opposite” of a GPU is kinda weird.

Graphcore has a strange chip (IPU) that loves tiny batches...but is also massively parallel.

It used to cost ~$100k. Now you can get one on Ebay for $160 bucks.

The catch is it's almost impossible to use.
