Many water facilities lack basic cybersecurity measures, making them vulnerable to adversaries.

First day on the Bluesky infrastructure team! I hooked up OpenClaw, and it has some amazing ideas about scaling and optimization!

Another reason to hate #Apple We're seeing more 2018+ MacBook Pro/Air donations — but Apple's T2 chip means even after iCloud sign-out and reset, the firmware stays locked to the original account.

Without donor contact, these machines are useless. :(

I've upcycled ~1,000 older Macs, but T2 era machines will end that. It's controlling, creates e-waste, and will only get worse. #righttorepair matters — Apple couldn't care less.

UK gov’s review of Mythos shows it completing challenge of approx 20hrs human expert time & 32 steps 3/10 times using 100M tokens. https://www.aisi.gov.uk/blog/our-evaluation-of-claude-mythos-previews-cyber-capabilities

Opus 4.6 did 28/32 steps max & 100M tokens is approx $900. More for Mythos when/if released.

Our evaluation of Claude Mythos Preview’s cyber capabilities | AISI Work

We conducted cyber evaluations of Anthropic’s Claude Mythos Preview and found continued improvement in capture-the-flag (CTF) challenges and significant improvement on multi-step cyber-attack simulations.

@adamshostack RTGs are becoming more and more rare and I believe NASA hoards every gram of Pu238 they can synthesize or reprocess for Dragonfly...

Also, Rosalind Franklin was already integrated and tested with solar panels long time ago.

Russians were offered to be famous for delivering it to Mars, they chose instead to be famous for invading neighbors...

Unsolicited advice to “just block and move on”, no matter how well intentioned, is not helpful or actionable for someone who’s the target of organized or persistent harassment. It’s ultimately just a dismissal, “shut up about your problems” couched in slightly more polite language.

@mattblaze There is a big divide on social media between the people who have a folder full of screenshots labeled "Death Threats (personal)" and people who do not.
