I'm sorry, can't find a picture right now. I call it "basket weave veneer", made by taking thin plane shavings, boiling them in a kettle and straightening them under weight and finally weaving them like a basket and appl

I work with collagen glues and boiled linseed oil all the time, and they work great together. I have made wafer thin all-natural composite materials using wood fibers (thin plane shavings) as the substrate, hide glue to hold it together and

There has been unusual hot and cold spells of weather on the high latitudes in the past year or so due to the arctic polar vortex behaving in an unusual way. My knowledge is limited, if there's a meteorologist reading this comment, ple

I started with Bate, Mueller, White: Fundamentals of Astrodynamics, which is US Air force material. It contains two courses, so you should skip some of the chapters at first. Then I read a bunch of research papers and more in depth literatu

Orbital mechanics and related mathematics like Stumpff series and Universal variables. Got inspired from playing too much Kerbal Space Program and Orbiter.

In a same vein, check out Wolfpack on Steam. It is a 1st person coop submarine simulator with WWII era Type VIIC U-boats for max 5 players per sub. I've done a dozen patrols with different 2-4 player crews and it's kinda fun.

You could take this one step further by using the __COUNTER__ macro to generate unique numbers in the preprocessor. Alas, this isn't a part of the standard (iirc), so you need to depend on compiler-specific features.

Well yeah, seeing that photo I thought that it looks exactly like bitumen but it can't possibly be it.

by exDM69 6y ago
No, beeswax, linseed oils, pine resin are not plastic. They can be used instead of plastic in many applications but they're still renewable and bio-degradable materials. Bitumen is a crude oil product, and quite nasty material indeed.

I guessed quite a few of these ingredients because I work with beeswax, tree resins and plant oils in the wood shop, particularly when doing instruments. I was surprised about the bitumen and its origin story (floating blobs in the dead sea

Yes, a pickup that has an output for each string is called a "hexaphonic pickup". Note that normal guitar pickups have one or two coils (humbucker) that span all six strings. A hexaphonic pickup has 6 or 12 coils for 6 outputs, on

While there are flight simmers who use VR, somewhat counter intuitively it's not really a good match. Also, it's a tiny market from a $$$ standpoint. In a flight sim you have lots of dials in the cockpit you need to look at, and l

I haven't shared the code in public but if you give your GitHub username, I can share it to you (and others who are interested) and you can reach out via email (address in commit log). I got inspired by Raph Levien's talk on Rust

Those "1000 lines of boilerplate" is why imgui and nuklear are so popular. If you're on a commonly used platform, say SDL and OpenGl, you can just copy all or most of it. But the magic here is that imgui and nuklear will inte

Lots of sw engineers dabble in woodworking on their spare time. It tickles a similar engineering nerve, but the lack of "undo" needs a bit of a paradigm shift. You can stare at a piece for quite some time but sooner or later you w

Yes, glued. Although "structural adhesive" is the preferred term. Race cars and carbon fiber supercars are built this way too, there is decades of experience in this kind of manufacturing for high stress environments.

There are gas turbine based buses and trucks used in eastern Europe where LNG imported from Siberia is plentiful. They're not common in my city, but there's (only) one on the bus line that drives by my house. It's only a bit

More than just the voltage, the 8581 had significantly revised circuitry and better opamps due because they had much more silicon area and a better process available. It sounds disnctively different too.

Spec development? No. But for bug reports, debugging and fixing bugs in the shader compiler, validation layers, etc they are pretty responsive to issue reports and pull requests.

Does Formula E still have the driver change cars mid race because the batteries are depleted? That's what they did in their first few years. I don't watch it, not because there would be anything wrong with the cars but the tracks

Learn how to sharpen a knife or chisel or axe or other tool. Suddenly every piece of hard steel turns into a tool when you know how to get it sharp. All you need is some abrasive (e.g. sandpaper at 600 and 2000 grit) and a piece of leather

It's not obvious how the hypothetical OpenMP for Rust should work. If you'd put #pragma omp parallel for in front of a loop, there would be no compile time guarantees of memory safety or freedom from data races. OpenMP is suitable

Would you like to point out specific instances of this "noise"? The C++ code looks like straightforward "C code" because it's using the OpenMP parallel for. If it dealt with threads explicitly it would not look as p

by exDM69 7y ago
The reason the C++ code looks simple is that it uses OpenMP #pragma parallel for, which is a very easy way of doing very simple loop parallelization. By contrast the Rust example uses parallel iterators from the Rayon crate. If the C++ exam

But plywood is made out of veneer sheets that have been turned on a giant lathe. There is only a very thin layer of fibers running one way, you can't really see growth rings in a layer of ply. CLT layers can be at 2" thick or more
