I don't think you can buy a single "MI300X" unit, right? Only the box with x8 of these at a cost of ~250K EUR.

There is more! I started to figure out how ADC/DAC chips actually work. I believe our CM6533 and its competitor the CM108 both use delta-sigma. The output isn't a staircase of those samples but a rapidly switching (MHz rates) 1-bi

Many countries now assume you have a phone. For example getting UK visa requires a smartphone. I don't think going without a phone is feasible nowadays. Another question is if going with a burner phone that has just sim card and bank c

sockmap has been through a lot of changes since then. Some done by CF (hi Jakub!) some by others, including bytedance and isovalent. Recently there has been a push to figure out the backpressure situation, so it's worth checking again.

(I'm ex CF) This is backwards. Nobody "allowed" anyting. CF serves a customers need. You can argue with the solution but you can't argue with the core problem. It's more healthy to start the conversation of _why_ CF

I've had more success. Flipper taught me about sdr, and I was able to reverse quite a lot from my garage door pilot. Then I went on an adventure of cracking Keeloq cipher, and I haven't stopped since.

Not necessarily. In classic C we often build complex state machines to handle errors - especially when there are many things that need to be initialized (malloced) one after another and each might fail. Think the infamous "goto error&q
