<p>“Functions use dynamic scoping. This is categorically a mistake, and one which ironically has been suggested to seriously mess up fexprs.” (links to Kernel)<p>It’s possible my interpretation wasn’t correct and the author was citing Kernel’s approach as sanity. That would make sense technically.</p>

<p>The dig at Kernel is kind of depressing. It's probably an evolutionary dead end, but god damn it, the world is better when people try things. Dismissing them doesn't make you cool.</p>

<p>I had Windows and Mac laptops back then, and the HN snobbishness around the superiority of the Mac was genuinely baffling.<p>My i9 2019 MBP with discrete graphics was probably the worst laptop purchase I ever made. Docking it to an external monitor would enable the GPU, so even when idling it would run the fans and drain the battery.<p>I’d read cautionary tales about Windows laptops being pulled out of backpacks scorching hot as they failed to shut down. But that happened to my Mac all the time, too.<p>The M series though is incredible. I can’t imagine buying a Windows laptop now.</p>

<p>Bun in its current state absolutely has issues like segfaults. As nice as it is, I moved off of it back to node for production.<p>Folks generally tolerate issues if they believe they’ll get better with time. I know I did for a while. If that confidence collapses, that’s not politics.</p>

<p>From my experience, a tiny alarm sounds, a voice says cyclist approaching and the door clicks to locked. At least I believe it did, I heard a sound.

<p>I wrote a library called Temper, which simulates the Rust/C++ memory model with atomics in a similar way to Loom. But it goes much deeper on that narrow domain, and to my knowledge it's the most accurate library of its kind with the largest set of test cases.<p>If you simulate using mock CPU instructions like memfence or LL/CS there's no guarantee your model fits your ultimately executed program.<p>Unless of course, you do something like antithesis and directly test what compiled. It's an interesting alternative world.<p>I've taken the liberty of adding you to LinkedIn - would love to grab a drink next time you're in the SF Bay area.<p><a href="https://github.com/reitzensteinm/temper" rel="nofollow">https://github.com/reitzensteinm/temper</a></p>

<p>At the intersection of these two topics, does Antithesis have any capabilities around simulating memory ordering to validate lock free algorithms?</p>

<p>You can still rewind by storing checkpoints, resuming at the most recent before the seek time and fast forwarding from there.<p>The updates thing is a shame. You can store multiple configuration files for balance patches, but executable code is much harder.</p>

<p>There's not a lot of churn in Unity, but that's more because they mostly fail to ship anything of significance than due to excellence in backwards compatibility.<p>I was in the audience when DOTS was announced, and a decade later Cities Skylines II showed how ill equipped for prime time it remains (not that the developers were blameless).</p>

<p>Yes, absolutely. I did that before vibecoding too, as rapidly editing and testing is so crucial.<p>The way Bevy's internal state is so easily saved and loaded is convenient for this.</p>

<p>Compile times are my biggest struggle, too. I'm vibecoding Bevy with parallel agents, and the bottleneck is often compiling the changes on my 7950X, not getting Codex to write them.<p>As far as file sizes go, I'd be really interested in how a Rust compiler that didn't monomorphize so much would perform. Right now you have to modify the source code to write polymorphic generic functions, but it doesn't strictly have to be that way (at least as far as I can see).<p>I wouldn't use Bevy for a web only game either, especially while it's still single threaded on WASM.</p>

<p>But this document does not. Note it says 12.5%, not 12,5%.<p>1 TWh on the scale of a country is very little - a 1 GW nuclear plant operating continuously would generate over 8 TWh a year.<p>Nevertheless the back of the napkin math of land requirements for solar check out, so it was probably just a typo and OP meant to say PWh.</p>
