@gabek Software engineers, in modern parlance, seems to be someone who is "full stack," but not in terms of metal to UI, but rather in business matters. E.g., someone who is able to prognosticate the future and come up with solutions to head off future problems, etc.

I'm not that person.

Give me a problem to solve. I'll solve it. Then give me another one. Repeat as necessary.

Intel, the company all of whose chips are defective, just held a demonstration of their self-driving car, although no car was demonstrated to drive.

This is some Bob Lazar level scamming.

This is even better and more concrete:

> access either userland address 0x000 or address 0x100 depending on the eighth bit of the result of the illegal read, loading that address and its neighbours into the cache. Because v is zero, the results of the speculative instructions will be discarded, and execution will continue. If we time a subsequent access to one of those addresses, we can determine which address is in the cache. Congratulations: you’ve just read a single bit from the kernel’s address space!

Meet Sci-Hub's Alexandra Elbakyan, the mastermind behind the liberation of 50 million journal articles that I refuse to call "stolen", shattering the $10 billion-per-year paywall of academic publishers.

@thegibson Google determined a code sequence that stops all speculative execution on x86 CPUs, called a retpoline.

It isn't a full patch unless all software is built with the retpoline feature though. :/

I posted this a while ago, but it seems relevant again. These PCB antenna designs are from a paper written in 2012

They're dual band, 2.4GHz and 5.8GHz, cheap to reproduce, and ideal for a distributed mesh network with good pickup even in noisy environments

Point-to-multipoint access can distribute traffic across multiple nodes going back to multiple backbone connections
