For months I've heard crazy stories about SF's reorganized street medicine teams, which are now forced to focus on "the list" ā a small number of homeless folks who've annoyed politicians or angry neighbors. This means every day they have to drive past people in urgent need of medical care. 1/3

SF Streamlined Its Street Teams. Now, Fewer People Are Getting the Help They Need
Street medicine outreach workers describe a new, expensive, and disorganized program that lacks clear objectives.

Just FYI, administrative warrants (like the ones used by ICE) are not judicial warrants (used by cops, signed by a judge). You do NOT legally have to open the door for an ICE officer with an administrative warrant *no matter what the ICE officer says.*

The year is 2035. I meet President AOC in the Oval Office. "You've done well," she says. "By telling men to dress gay, you've lowered the population rate by 90%, thereby reducing carbon emissions." She slides me a manilla envelope. I can now afford a home in a walkable neighborhood

You can bypass security on the RP2350 by glitching the OTP power supply (which does not have a glitch detector on it). This causes OTP to supply "guard data" instead of real data, and interpreting the guard data happens to enable RISC-V mode, which can do anything.

Oh, I never posted my gotofail story on here. Early 2014, someone came to me about a catastrophic vulnerability in Apple's TLS implementation. I shit you not, they'd overheard someone at a bar drunkenly bragging about how they were going to sell it to a FVEY intelligence agency for six figures.
