My latest blog post is about a class of deadlocks that comes up in async Rust: https://t.co/Ml1mEA8zu2

@CharlesFLehman @uaustinorg I'll need you to ELI5 here, but my understanding of the popular story of Prohibition in the US is that it's not really "we decided we missed drinking" but rather "Prohibition created the mafia". Does that story stand up to scrutiny? Was it both?

I was recently diagnosed with a rare autoimmune disorder called anti-NMDA receptor encephalitis. It's a "disease of chaos" that completely upturned my life for a couple months.

I wrote a blog about it that goes into more detail and discusses prognosis.

@KelseyTuoc I don't think it's automatically wrong to argue that some things (e.g. memorizing a book, or imitating another painter's style) are fine if a person does them but bad if an LLM does them. But I sometimes wonder whether folks *realize* they're drawing this distinction?

[Jack O'Connor @oconnor663]

@sgodofsk @KelseyTuoc I think there's a lot of value to people in being able to tell our children, truthfully, "When we see suffering, and we know how to prevent it without causing more suffering, we do that." That can be compatible with animal suffering being heavily discounted, but not *totally*.

@LeahLibresco Not the same time period, but maybe Admiral Jerjerrod is the hero we need right now: https://t.co/LAuk3nnni7

@Noahpinion I don't necessarily disagree about the effect of smartphones, but at this point I think it's malpractice to answer "why is the world getting worse" questions without challenging the premise. Gay marriage was still illegal when that photo was taken. Solar power was expensive.

@jedisct1 @FrancescoCiull4 Not disagreeing, but another aspect of this change that's very Rust is that the edition mechanism will let us switch the range syntax from the old type to the new type without breaking the world.

@zombodb @thinkx @daleverett @daltonmeon Is it time for Astral to revolutionize the world of Perl tooling 🤓

[Jack O'Connor @oconnor663]

@mitsuhiko If a model can find *all* your memory issues, that's pretty good. But if you're in a perpetual cycle of new model comes out --> new flood of issues to fix, that's pretty bad. Also interesting that this cycle breaks the "most issues are in new code" rule of thumb.

@klaehnr @elonmusk If something's preventing the different branches from going to war with each other over resources, then isn't AGI ultimately in control of all the branches? (I haven't read the Culture yet.)

[Jack O'Connor @oconnor663]

@bannon1975 @MW74164398 "Goal" here is trying to swap a thorny problem out for an easier one. No one thinks "make the gap bigger" is their terminal goal. (That's closer to an insult really.) The hard question is whether "help each student achieve as much as they can" widens the gap as a *consequence*.

[Jack O'Connor @oconnor663]

@LeahLibresco I assume the original intent of these rules was to keep three jobs for three people, rather than to make one person get paid three times as much? But then the rule was written in stone and things shifted over time?

@Fiat_Lux00 @Osinttechnical I probably wouldn't debate this if we didn't know whether the pilots were ok, but local news seems to say they're ok, so: The biggest concrete benefit to the military from these shows is probably recruiting? You'd need to compare the cost with the number of pilots you get.

[Jack O'Connor @oconnor663]

@DavidAFrench This is how they were arranged right when the last ejection seat fired on the aircraft stuck below. It looks like just *barely* enough clearance to make it out without hitting the other one. Fingers crossed.

[Jack O'Connor @oconnor663]

@JohnHMcWhorter I think what's happening here is just hypercorrection from our elementary school days. It's easy to remember the "t" in "soften" (because we learn to spell "soft" first) but hard to remember the one in "often", so we get corrected more on that one, and some of us start saying it.

[Jack O'Connor @oconnor663]

@the_engi_nerd Is the pilot really expected to collide with the half-shattered edges of the canopy like that? I've heard that ejection is violent but that's worse that I expected.

[Jack O'Connor @oconnor663]

@_Felipe (I am aware that memory leaks are not UB in Rust. But I assume "stability issues" means the same thing in a Zig program that it does in a C program.)

[Jack O'Connor @oconnor663]

@_Felipe Jarred's description of what it's like to maintain Bun doesn't make it sound like a memory-safe program: https://t.co/3oxxNLigHa

[Jarred Sumner @jarredsumner]

why: I am so tired of worrying about & spending lots of time fixing memory leaks and crashes and stability issues. it would be so nice if the language provided more powerful tools for preventing these things.
