Part 15 is pretty clear that any harmful interference should be minimized[1]. Even though it's low power that doesn't mean that it still can't be picked up. Just because equipment is sold at retail doesn't give you a fre

I think when there is common set of facts that could be agreed upon that might be possible. The rejection of basic facts, outright lies and contempt of science. I don't know how you can have a discourse in that environment.

Most C++ compilers I've worked wouldn't let you use it unless the compilation unit was compiled as C and then linked externally. In the same way I could totally define alloca in a C symbol and then just extern it into Rust if I w

I've written my share of systems level C++ in performance constrained environments professionally (gamedev, embedded systems). Never touched goto, alloca and branching usually stayed out of hot code through DOD approaches. Not really s

by vvanders 6y ago
Even then last I looked C++ doesn't have it either, it's exclusively a C99 feature. For me the downsides outweigh the upsides of alloca and I usually find other approaches(free list, arenas, etc).

This is pretty solid. Text rendering is one of those things that someone thinks they can get a basic version running in a week or so and 5 months later they're still trying to address rendering/memory/performance issues for a

I knew some game developers who put one or two glaringly bad visual choices in each milestone deliverable so the publisher could say "Change X!" and they feel like they'd made their mark. That left the rest of the build mostl

140F/60C is not really out of band for a GPU, usually throttling starts around 75-80C.

As someone who's spent a few decades working in C++ codebases I'm not sure how this is a Rust specific problem. Last large-scale C++ codebase I worked on took 60+ minutes to compile when you touched the precompiled header. In fact

Yeah, most pumps are AC and this was DC so I didn't have a off the shelf solution. With a PLC, analog input for the pressure sensor and SSR to drive the PWM it was fairly straightforward to put together. Hardest part was getting the PI

If the system doesn't work for the people then they won't want to work with the system. Food/shelter/inequality all drive that wedge and the sooner we bring things back to a balance the sooner we can work to fix our sy

Yup, Automation Direct is my go-to "cheap" option for this. They also make some very low cost PLCs that work pretty well. I built a solar powered DC irrigation pump with proper PID control+SSR to support varying flow rates(most ir

Yup, and a lot of the Danger DNA found its way to Android as well. The Hiptop had a Java VM, app store, push(!) IMAP/POP3 email, media support and more.

Privilege isn't a binary thing, it exists along many dimensions. I'd hope you could understand that just because someone has a finite set of options doesn't mean they can't be impacted significantly by political policy d

If you're not in a place of privilege life is politics. A old co-worker of mine couldn't get permanent residency for their legal partner. As a result rather than staying in the US they both moved back to Canada. Honestly I don&#x2

I feel like we're talking past each other a bit and maybe our experiences with external engines haven't matched up. I've seen whole platforms which were on the milestones in the contract delivered in an incomplete and unusabl

You might be assuming too much, I never said Unity at any point. The larger point I was trying to make is that an internal team is aligned with your goals and can support you. And external engine is tied to their own goals that might not al

Honestly I've done both on multi-platform engines and the huge advantage of the in-house engine is you can line up the releases and breaking api changes in a way that works with the internal teams vs throwing it over the fence. Last in

It depend on if those features coming with major versions include one of the platforms you intend to ship on... You can pull new versions while under development. I've been on a team that did it and it was not fun. Usually involved s

If you don't actively make the real-world connections to the theory then most students will just memorize the coursework and then forget it later. The number of times I have to walk through why linear memory access matters, how caches

That book is in my top 3 technical books of all time. It's basically data structures for 2D/3D space. It's also the only algorithms book I've found that actually has a whole section on how to write cache aware algorithms

If you want to do that you can grab a PlutoSDR for ~$150 and supports gnuradio right out of the box. That said the post was a tour-de-force in cross functional engineering, truly impressive stuff.

It gets really annoying on no_std, which makes me happy to see this making progress in the language.

To this day I still write #define WIN32_LEAN_AND_MEAN reflexively ahead of #include <windows.h>, it's a muscle memory I can't unlearn. Be careful what you wish for.

That's because data oriented programming has already succeed on a large scale, you just might not recognize it. SQL is about as data-oriented as it gets, you have a programming model that's constrained and focused on data layout,

Bit rates are usually in the 2400-4800bps if I remember right so Opus is still a bit too large.

Honestly a little surprised you need a permit for the standard engine power stuff. It's been ages since I've been involved with the hobby but we used to not need one until we stepped above E class. Bigger stuff is fun but also hit

If you enjoy fetching your rocket from a tree you can go higher. Back when I was involved with some of the higher power aspect of the hobby(J/K/L/M class) we'd go our to the desert where retrieval was a lot easier. Even

Proprietary is allowed if it is documented, the issue with most of the digital voice modes is they are protected by patents.
