You can't really stop wood movement or even reduce the amount it moves. It can be slowed down a little with some finishes (then you have a "wood-plastic composite"). Kiln drying (do you mean this by "torrefying"?) w

On the other hand, if you build heirloom pieces with nice joinery, you want the glue to fail before the wood does. When that happens, it's an easy repair. If there's damage to the wood, it's a much more complex affair. I use

In addition to wood movement, there's another important factor when it comes to hobbyist woodworkers: accuracy. With modern adhesives and precision machining like Mathias' work will make mighty strong joints even out of the simple

Afaik they need to provide logs. Of course they could cheat but the penalties of getting caught are severe. The limit isn't very high, though. A single box with a few GPUs is enough to hit the limit.

Curious fact about F1 aerodynamics: the regulations limit the computing power of the CFD clusters they use. The limit is about 30 teraflops but the teams can trade off less teraflops to more wind tunnel time. As someone working with semicon

These days the Astronomical Unit (AU) is defined exactly (149597870700 m), but historically AU was used to measure relative distances in the solar system because the distance from the Earth to the Sun was unknown . The transits of Venus in

I guess I should have been more specific. In my country, train drivers still have engineering degrees. Maybe not everywhere any more. Back in steam engine days the job was more difficult, and needed higher education than today. And train si

There's more in it than you think, it's not just about escapism. Driving a train usually needs an engineering degree in real life, it's about managing the momentum of a thousand ton vehicle up and down hills. Reversing a truc

If you want to see what happens when a glove catches a table saw and other spinning tools, do image search for "degloving" (NSFW). There's no good reason to wear gloves when woodworking with machines.

To further elaborate on this... Flight simulators as a game genre has all but disappeared. There used to be lots of flight simulator games, like F-15 Strike Eagle and Red Baron, etc. Every now and then there's an "arcade flight

When getting started with a new OpenGL project, the first thing you should do is to enable the debug output [0] w/ glDebugMessageCallback. You also need to enable the debug bit when creating a GL context. This will give you human reada

I guess the reason for applying the tax this way is that tech giants (and non-tech corporations) use creative accounting tricks to avoid making a profit and thus paying taxes to the countries they operate in. It's either disguised as l

There is a big difference. When typing on a keyboard, you can make mistakes and take your time. When playing a musical instrument, you need to hit the right note on the first attempt and at the right time or it'll sound obviously wrong

This is a shortcoming in general. There should be a binary format targeted for JIT-able intermediate representations. Or just a specification on how to put IR code inside ELF files. Now we have (at least) three different IR formats that are

No, there are no disadvantages to using the Multiboot protocol, but there are numerous advantages. The biggest advantage is that your kernel images are a bootable, debuggable ELF binary. The emphasis being on "debuggable", you can
