Yeah, there are lots of options for splitting mauls, forestry axes and camping hatchets but the only right handed (bevel on one side only) broad axe I've found is the Granfors. If you happen to know cheaper quality alternatives, I&#x27

How is the Granfors axe? I'm considering getting a right handed broad axe from them, but it is quite expensive. I have their froe and it seems to be great. I'm contemplating either buying one from them or going to a blacksmithing

I do this kind of woodworking as a hobby. A lot of the material I use has been riven or split from firewood or yard trees. I mostly use dry or half dry wood, but sometimes also green stuff. It is a bit time consuming, but not that much when

The material they show in the article is massive. Thick, long and heavy. Even if there are kilns big enough, the wood would no longer be straight after a fast kiln drying. A 50' 3x3" board would be twisted and bowed so much that t

Kiln drying doesn't produce ready to use lumber for fine woodworking or demanding applications. It's fine for construction material but needs additional seasoning and acclimatization in the environment it's going to be used i

No, it's not constant time. Depending on implementation details, you end up putting different elements in different buckets in different cache lines and that creates side channels. Radix sort will perform differently for an input that

An initramfs image is not required if you can mount root directly and don't have any drivers or firmware that need to be up before the real init. Some of these can also be bundled in the kernel image, but an initramfs makes things so m

Am I correct in thinking that using this Fibonacci method of mapping hash values to buckets will solve the "accidentally quadratic" behavior in a Robin Hood hash table? Rust's default hash table suffered from the issue but t

What the C++ (and C) stadards could use is a native type for SIMD vectors. In other words, standardize the GCC vector extensions [0] or some variant thereof. Just adding a new header-only library for vector arithmetic isn't something t

At work? No. Outside of work? Yes, but most of that doesn't involve programming. Mostly doing stuff with pre-industrial revolution era woodworking and blacksmithing. I do have a few interesting programming side projects too, but I have

While Vulkan is a bit verbose, it's not an order of magnitude difference if you follow modern OpenGL best practices. If you rely on default state and use the default framebuffer and rely on implicit synchonization, you can squeeze it d

While there are differences between Clang and GCC language extensions, most of them are compatible or at least can be worked around with some relatively trivial hacks. Compare this with trying to support MSVC, which supports none of the ext

It's also practical for hw implementation and has other nice qualities. E.g. comparisons and sorting are easy. Radix sort works for floating point (with some bit magic). Terms and conditions may apply (oddities w.r.t. INF, Nan, etc).

With current technology, a wafer is 10" in diameter (254mm), the aperture size limiting the die size is around 900 mm^2, so a chip is at most about 30x30mm. This would make it about 60-70 chips per wafer at maximum chip size (e.g. high
