Reading the article and I didn't see writing fast Rust programs as easier listed(only Go). The callout was for sharing data between threads which I think is an area where Rust has the edge over other languages.

I would argue the opposite, there's a really strong skill transfer between gamedev(esp on the engine side of things) <-> embedded development. Both deal with hard constraints(performance, memory, storage) and you use similar appr

That doesn't sound far off from a PTO generator, assuming you've got the right interconnects exposed seems reasonable. From my limited understanding most diesel electrics go Diesel -> AC -> DC -> AC -> Wheels. If your

While you can't use the motors 1:1 from what I understand a lot of the development of VFD AC motors happened in the locomotive space[1]. The traction of a DC drive vs AC drive is significantly different(the below article cites at least

The upper bound is interesting but my limited intuition is it's a very upper bound. LTO/LTCG will drive that down a lot. Last time I was looking at Rust binary sizes things like building the stdlib with heavy LTO/opt size had

That doesn't track with either the CDC data above, other studies[1] or what we know about other variants. [1] https://mobile.twitter.com/EricTopol/status/1476212140956553...

Gonna need to cite some sources there. The current recommendation is to get a booster because it both reduces the severity of the disease and the chance of either catching a breakthrough infection or another variant[1]/[2]. [1] http

Having owned both CUT without any emissions control(1981) and a Kubota w/ DPF, I'll take the DPF every day. It's quieter, cleaner and the emissions controls are even more straightforward than other modern diesels. If you have

Same for SoCal, I have fuzzy memories of flipping through boxes of shareware 3.5"/5" floppies and all sorts of with various hardware pieces.

Depending on what you want to do you can get away with a RPi and RTL-SDR which are pretty widely available. Most wireless weather stations use ISM bands, I used RTL_433[1] to pull the raw data and quite a few popular stations already have t

These are all fantastic but Yooper Scooper is really inspired.

I would agree, if we're talking CUT/SCUT you're in the realm of something that is easily serviceable(and the market doesn't really do DRM/lock-out currently) however these are different scale machines that are much

While I get where you're going with this however if you use small binaries that are built for efficiency then your process start time isn't 100s of ms, it's a least an order of magnitude faster. Using a single process also gu

Only thing that comes to mind immediately is VLA/alloca but I'd have to check. Most of the gnarly pointer things are fair game and work just as well as their C counterparts.

West WA doesn't have the infrastructure to clear the roads(which makes sense given how infrequently it snows) combine that with some steep areas and it's fairly predictable what happens.

From my experience there's a bit more dynamics in there. In particular the publishing agreements(I've been privy to a few) are structured in ways that the developer takes a substantial amount of risk and very rarely gains the rewa

One of the advantages of fixed hardware is you can tune for that hardware directly. We used to bake content and design code with specific cache line sizes in mind. If you know you have a fixed memory budget for graphics/sound/etc

The part of 5G that gets thrown around a lot with high speed and capacity is mostly based on mmWave bands(think 10's of Ghz) which attenuate incredibly quick. Most of them are nearly direct line of sight. You already see some issue wit

If you have problems with wifi resiliency I've got bad news for you about the wavelengths 5G uses.

Fair, but feels like that significantly reduces the utility of pinned types then if for certain values you lose the ability to mutate values when the compiler overwise knows that there is a single mutable reference.

by vvanders 5y ago
I would largely agree, in the cases where I've needed something pinned I just drop to Box'ing to, keeping the box internal and managing the pinning directly. It's annoying because you lose some classes of things that you may

VSCode is still pretty sparse on the debugging side of things. I've tried to chase down heap corruption with it and the lack of data views, complex watch/breakpoints really limit it in that scenario. CLion is getting there, it&#x2

This is pretty good overview. One fun tricks we would regularly do was move all the background audio off the disk and into GPU ram. We'd stream just enough that we wouldn't saturate the bus but could get back 20-30mb of system mem

"Most" ends up being surprising(ex: ARM has a fairly weak memory model). I've seen a lot of code with aligned access and extensive use of "volatile" in MSVC/x86 explode once it was ported to other architectures

I have one and can confirm it has a great battery and is snappy. They're a little hard to find in certain configurations but for a "gaming" laptop it's a pretty decent daily driver.

Subspace was another impressive one from around that era. 50-100 concurrent players on 28.8/56k. They used a totally different technique(dead reckoning + game design that was about prediction) but it was pretty smooth given what averag
