I'm incredibly pleased to announce that the microcode for the Intel 80386 has been decoded.

It was a group effort by a bunch of talented people to extract and correct the physical bits, but the major work of decoding them was done by reenigne - you may know him from such incredible PC demos as 8088 MPH and Area 5150, as well as being the person who decoded the 8088 microcode previously.

Please, check out his writeup.

apparently fennec/firefox android has a countdown to the world cup on the new tab page now

also, for some reason it is using random fedi users' profile pictures as the icon for the berkeley.edu.pl shortcut instead of the actual favicon, which is very weird

more exams today

TIL, the SD card specification allows cards to report they support a maximum current consumption of… 65 amps

fun trick: if someone gives a hosted LLM a skill that lets it fetch web pages (directly, not through some third party scraper service) and it's hosted on AWS, you can often trick it into fetching data from the AWS instance metadata server (IMDS) at 169.254.169.254 / [fd00:ec2::254]. the higher end models tend to refuse if you give the IP, but you can just spin up a domain with A/AAAA records pointing at that IP and request that instead. if IMDSv1 isn't disabled you can get secrets out of it.

You only have a few days left to tell the FCC that they should stop trying to force broadcasters to classify trans and nonbinary people as inappropriate for children to see on TV https://skepchick.org/2026/05/the-fcc-wants-to-rate-lgbtq-as-obscene/

As part of the hardening effort, and because ActivityPub is “basically email”, I propose Sharkey should switch to federation over SMTP only

server reboot time for more kernel upgrades (fixing pintheft)

For Akkoma and Pleroma users, this says:

Unofficial Announcement: We just released 2026.5.4-beta.0 of Misskey, which includes important security fixes. Official 2026.5.4, along with security advisory, is expected to be released several hours later due to timezone differences.

alright pretty much everyone figured out how it works instantly, and it's been like 40 minutes without mastodon announcing their security release on their fedi profiles despite having the release published on github. heres a post
