Not really if you've ever driven a manual transmission. Regen usually is stronger but the drive feel is not dissimilar.

Yup, fully agreed Zig stands above others here. Cross compiling C/C++ is just a special kind of hell. Each target always has some sort of bespoke toolchain and build environment constraint that add so much unneeded complexity.

I would not include Rust in that list, in my experience rustup and cargo are miles ahead of C/C++ when cross compiling.

"Let it crash" is largely about restarting systems to known good state in an expanding scope. The Zen of Erlang[1] covers it really well, it's a longer read but well worth it if you want to understand a lot of the design choi

Oh it's very much a thing although maybe in different contexts. My tech director in games used to have a ~40mb static array at the top of main.cpp with a big comment along the lines of "DO NOT TOUCH". When we'd come up o

Yeah, it's a pretty neat ecosystem. PLCs are kinda like the Legos of automation, incredibly easy to mix and match with a fair number of (insecure) standard protocols. I briefly toyed with the idea of building out some open source hardw

One thing missing here and in most of the visual programming discussions since it sits in a somewhat adjacent SCADA industry is Ladder Logic[1]. It was pretty illuminating how many parallels ladder has with the visual and scripting solution

Not really surprising, radio only works if we all play by the rules. Even a small 5w transmitter up high enough can easily cover over 100 miles. Most radio groups tend to be disaster recovery and communication adjacent so they care about in

I think it depends on a lot on the studio and culture. I don't think I saw a single unit tests before I left gamedev(a few smoketests to make sure the game didn't crash but that was about it). I also rebuilt our audio streaming sy

Java's MUTF-8 makes me want to eject it into the Sun. Makes interop with JNI extra fun.

Bruce Dawson taught a 100 level class at the college I attended, it's been a while but I think the class title was something around image processing. The first or second assignment was to copy one image region into another, little did

The HD2 from around that era was also a stand out. I still remember seeing one for the first time and just being floored by the 4.3" form factor.

https://en.m.wikipedia.org/wiki/Radio_propagation covers it a little bit. The short answer is that wavelength(aka frequency) vs raindrop size causes signals to scatter instead of attenuate and you can pick up a fractio

Yeah, a lot of this is providing visibility to low visibility high impact work or Anchoring[1] work so people's impact is correctly reflected as a part of whatever review process an organization does. [1] https://mekka-tech.

I think we're working from different definitions of learning curves. I include in the learning curve understanding your memory ownership model, not introducing use after free, heap corruption or other failure modes. I would argue that

by vvanders 5y ago
Shared ownership is code smell to me regardless of the language, I think Rust just makes it a bit more high friction. Language difficulty I'm having trouble seeing how C++ isn't harder there. You have decades of features, lots of

by vvanders 5y ago
Yeah, but rightly so those are "escape hatches" because you can leak memory with Rc/shared_ptr. With C++ unless you have someone experienced on a team there's a host of "unknown unknowns" that feel like the tea

Having written C++ in one way or another over the last 2 decades I still get burned by that surface area. Last week it was a combination of forgetting the exact specifics of RVO hitting the implicit copy constructor that was causing things

Having worked in both domains on the technical side one thing they share in common is no one really knows what makes something "fun" or makes UI/UX "intuitive". There's no sure-fire formula and the most success

Ah damn that's a real shame, something to be said about how rarely restrict is used(I usually only touched it for particle systems or inner loops of components where I knew I was the only iterator).
264.
by vvanders 5y ago
One of the things I'm really excited about for Rust is restrict semantics are baked right there into the language with &mut/&. I think there were still a few LLVM bugs to flush out(because very little C/C++ code uses

Yeah, I automated some stuff out in our greenhouse, I ended up going with a PLC[1] which is a bit more robust and designed for reliability and industrial environments. They're very much like (expensive!) lego bricks that you can easily

Look into community solar in your local area. It's utility scale solar and you usually get an offset or pays back to shares depending on how it is structured.

Can confirm that Lua does run in WASM in the browser: https://github.com/vvanders/wasm_lua I sometimes wonder what the world would be like if Lua had zero based indices and saw a bit broader adoption. It's such an

I think we're mostly arguing about how useful the various approaches are. At least for me print debugging is a measure of last resort unless I want to extract some historical data out and I know it won't influence the timing of th

You seemed to be drawing a parallel between no-code -> "not as powerful", in my experience they're different tools for different use cases. I also don't think they're nearly as no-code as you call out. VS' w
