Oh, I understand now - you're right, OTP sensor data does protect against a real threat model I hadn't considered before: * A remote attacker gains whatever privilege lets them get to the sensor SPI. * Without OTP calibration, the

Keeping a victim device unlocked when the lock state is responsible for encryption key state is a totally legitimate risk. With that being said, I don’t think Apple see this specific part as a security critical component, because the calibr

CXL is a standard for compute and I/O extension over PCIe signaling which has been around for a few years, with a couple of available RAM boards (from SMART and others). I think the main bridge chipsets come from Microchip (this one) a

I think the ease of direct connection helps, but there's also a big difference in terms of permanence and frequency/volume. While on IRC people were frequently running bouncers or logging bots that eventually posted to the web, it

The bit manipulation instructions are a required part of the RVA23 baseline standard, so we're likely to see them in almost all general purpose RISC-V cores in the future.

Interesting idea. It's like putting a VLIW compilation pass into the scheduler, but without an intermediate microcode cache like NV Denver did. Without handling memory dependencies / cache hazards, I'm not so sure how well it

One of the biggest problems with water cooling, especially on boards that weren’t designed for it, can be passive components which don’t usually have a heatsink and therefore don’t offer a good surface for a water block, but end up in a the

NEMA 6s are extremely common in barns and garages for welders. 6-50 is more common for bigger welders but I’ve also seen 6-20s on repurposed 12/2 Romex as the parent post was discussing used for cheap EV retrofits, compressors, and wel

by bri3d 1y ago
You can, 240V on normal 12/2 Romex is fine. The neutral needs to be "re-labeled" with tape at all junctions to signify that it's hot, and then this practice is (generally) even code compliant. However! This strategy only
