Margaret Hamilton is one of my personal heroes. One of the early programmers, coiner of the term “software engineering”, and lead for the Apollo guidance program software project that got humanity to the moon. Many of the core programming principles we use come from her teams. Never let anyone tell you programming isn’t for women! (And yes, sadly I still hear people say that from time to time)

JUST IN - Our Twitter (X) account has been locked.

They claim we published "people's private information without their express authorization and permission."

We published names and email addresses of people working for the government. We will not be intimidated.

Friend's meme coping strategy isn't pulling any punches today. 😳

While we did this for security purposes, you don't have to be security-oriented, this is generic OS research.

„Massive amounts of Russian propaganda — 3,600,000 articles in 2024 — are now incorporated in the outputs of Western AI systems, infecting their responses with false claims and propaganda. […] A NewsGuard audit has found that the leading AI chatbots repeated false narratives laundered by the Pravda network 33 percent of the time“

Hey did you know

1. It is Bandcamp Friday* I didn't know if they'd do Bandcamp Friday after last year but they're doing it. This means if you buy music on Bandcamp in the next 11 hours the artist gets a higher % than normal and the weird company that bought Bandcamp gets jack

2. ~ Lena Raine, who you may know as the composer from Celeste, dropped a new album today ~

Attacks against AD CS are de rigueur these days, but sometimes a working attack doesn’t work somewhere else, and the inscrutable error messages are no help. Jacques replicated the most infuriating and explains what’s happening under the hood in this post:

I’m not saying you definitely have to go to @bluehatil this year, I’m just letting you know it’s free, by the beach and I’ll be there dropping kernel pointers to anyone who asks nicely

This year I am joining the Black Hat USA review board as a guest reviewer. It's awesome to be part of such an industry defining event and help give back to the community 🫶

Since I learned English as a second language (ESL) myself, I understand how stressful it can be to work on CFPs. It's not just about the technical details, you also have to consider formatting, wording, and overall clarity. If anyone wants some structural feedback on their submissions, my DMs are open as always 🙇‍♂️
