You surely meant capacitors, not transistors

How so? PGO might indicate that most of the time arguments are in bounds, but that's not enough. It has to be a proof with 100% certainty before bound checks can be removed

Or even use acl(5), which is simplier than making arbitrary groups.

You can, in fact, give compiler a hint wether the branch will be predictable or not. E.g. clang has __builtin_unpredictable().

He only gets 4-5Gbps in the other direction.

Inderect call cost is a few cycles, if predicted. Now, you can argue, that it may be mispredicted and misprediction would cost about 20-30 cycles. But if it is mispredicted, then y…

can't help myself: how common to see code like https://github.com/oven-sh/bun/blob/main/src/bun_core/string... instead of simple ilog2()? I guess, ut somewhat explains how they got…

yes

I assume you mean container, not VM. But yes, container makes it harder.

The attack gives you ability to overwrite any cached page. So you don't need to be root to "edit" /etc/passwd.

setuid binaries are not the only way to get root. E.g. one can change /etc/crontab or /etc/passwd. Or add trojan to /bin/ls and wait until admin type 'ls'

Apparently it is both...

If you "forget" to mark COW memory pointer as no-write, the net effect would be same, would it not? If I'm reading the diff correctly, the problem was that code missed to mark some…

How would've memory safety helped here?

Another data point: AMD T14 G4 with s2idle draws about 0.4% per hour of sleep.

Lenovo sells ThinkPad T-series laptops as “Linux-supported.” However, if you happen to buy an AMD version of one of these laptops, you may be surprised by how poorly the Wi‑Fi work…

Right, I misread the spec.

What kind of usage do you envision for 245TB drive with read speed of 3GB/sec?

QLC retention reported to be around 1 year in unpowered state. I would assume, that drive does background refresh, though. No idea what effect it has on total drive lifetime. It is…

Zelic discovered 73 security problems with uutils, 7 critical, 11 of high impact, 29 of medium and rest is low.

Not really. PgUp, PgDown are missing. It is possible to configure software combination that would emulate them. But emulation is emulation.
