Rust can be called from C the same way as C++ can. You need to export unmangled extern "C" symbols. Not quite frictionless but there are helper utilities for this. If the Rust code uses the "StupidAlloc" allocator, it sh

Unlike all your examples, milk is not trademarked. Additionally, there are a lot of examples where the term milk is used to describe a non-dairy product. E.g. coconut milk. This is nowhere nearly as clear cut as you portray it.

The source you refer to is talking about municipal housing, which is just normal rental housing owned by municipalities. There is indeed a lot of those and it sure helps keeping the homelessness down together with social support. There are

That's two or three apartment blocks, so maybe 200-500 apartments? Don't have exact figures at hand. The municipally owned rental housing (available to anyone) which you talk about, together with different forms of social support

by exDM69 3y ago
That is a different matter. Municipalities own a significant amount of housing available for rent. These are available for anyone but there are societal reasons why someone might be preferred (e.g. single mother), while others are in the qu

This is incorrect. There are only a few houses for this purpose in the Helsinki Area, and they are actually in quite nice locations and far from each other. No-one in their right mind would live in these houses if they have an alternative,

Yes, most of the homelessness in Finland is driven by substance abuse and mental illness too. It's mostly alcohol, amphetamines (meth included), buprenorfine and benzos from Eastern European organized crime and fentanyl is not as commo

The issue with runtime instruction set detection and dynamic dispatch is that it needs to be at a rather coarse level to be beneficial. Take a simple 4-wide dot product for example, on x86_64 you'd have 3-4 different implementations (S

What a visionary article and a delightful read. To give another context to look at this in retrospective, here's [0] a die shot from a 2n3906 transistor made in 1965 (still available today). It's roughly 60µm * 60µm in size. By co

No, not really. LLVM is not a C compiler, it consumes an intermediate representation. Clang is the C compiler which produces LLVM IR. Likewise, GCC contains a C compiler but the machine specific parts like the codegen take an intermediate r
