@Sosowski @BurnZeZ Also, thinking about it, my gut says that the naturally "right" way to model input on Linux is as a network. AF_EVDEV? If events are packets, ALL the filtering, rate-limiting, tunneling, observability (wireshark), and BPF-driven payload mutation (i.e. key remap) Just Work.

Lenovo has replaced the right control key on their otherwise-pretty-nice latest X1 Carbon (warranty replacement) with a copilot key. Fine. I won't begrudge some Microsoft PM "AI impact" in his self-review. But know what I do begrudge? The scancodes, plural. See, the copilot key

@anaisbetts @stephc_int13 @phenlix NT does relocations on the fault path, leaving the resulting page clean and discardable (because we can rebuild it from disk any time we want). I've been trying for years to get Linux to do the same optimization. Doing so, we transform basically all .rodata into clean pages!

@lefineder Hannibal was just the one overworked employee who keeps the company afloat with absolutely no resources, and the board of directors complain about why it's taking so long.

@andersonc0d3 All that, but we can't properly support Intel Thread Director because adding one (1) MSR read to switch_to() would be Too Much Context Switch. Thus, Linux battery use continues to suck. Today's system programming lesson brought you by the letter F and the word "obstinacy".

Verdi is the first proof that Raft's state machine safety implies linearizability In other words demonstrate state machine safety get linearizability for free But how do you demonstrate a global property like state machine safety for an implementation? https://t.co/uzlpUzGAZa

Dear Microsoft friends: why do you *still* need to run shell namespace extensions in-process? Come on. We don't need Cloud Files or ProjFS or whatever exotic other thing you have today. COM is *already* built for out-of-process work. All you need is a version of IShellFolder

*sigh* There is no such language as “Elvish.” There are elvish LANGUAGES. Sindarin. Quenya. Black Speech. Fun fact: Galadriel, Elrond’s mother-in-law and therefore Arwen’s grandmother, is the last native speaker of Quenya in Middle-earth.

The sun? Sol? Child's play. We really need to be looking at ways to turn the Milky Way's central black hole into computation.

Just the very early stages of the singularity. We are currently using much less than a billionth of the power of our Sun.

@sarah_cone When I was about 14, we went to a company that manufactured oxygen sensors. You dip this probe into beer, sewage, or canned food a-stewing, and it tells you how much oxygen is in the slurry. It's got two electrodes, and there's some kind of electrochemical reaction that
