Elon Musk’s claim the X DDoS is from “IP addresses originating in the Ukraine area” is missing a key fact - it was actually IPs from worldwide, not just Ukraine.
It’s a Mirai variant botnet, made of compromised cameras. They specifically targeted a Twitter ASN which had origin servers not behind CF

I got Linux running in a PDF file using a RISC-V emulator.
PDFs support Javascript, so Emscripten is used to compile the TinyEMU emulator to asm.js, which runs in the PDF. It boots in about 30 seconds and emulates a riscv32 buildroot system.

David Lynch gave us the language we needed to better articulate the indescribable strangeness of our shared reality. “Lynchian” is so overused because it’s a viscerally understandable word without any known synonyms. I can’t imagine a more beautiful artistic legacy than that.

For the hackers among us: o1 can do @halvarflake.bsky.social 's crackaddr-mini without any problems , which no other model can do. It's going to revolutionize the AIxCC program and automated vulnerability finding in general.

In 1999 I underwent a difficult brain tumor surgery. It resulted in hearing problems. I had to deal with this in school, college, PhD, and now in my professional career. I'm sharing my story with a hope to help others who might be coping with difficulties. blog.lukaszolejnik.com/invisible-di...

Vulnerability names: this is log4shell. We named it this way because it's in log4j and gives you shell.
Threat actor names: this is HAIRY EEL, aka VIOLIN HIPPO, no relation to VEXING MACKEREL. Also known as APT-74, formely APT-C-92. We named it this way because he's a guy in Bulgaria
