That depends on what you want to containerize (which I assume you are after? If you don't containerize it works just like any other distro--it will be transparent to the IDE (because the IDE doesn't care that suddendly your gcc in

It works on top of any Linux distribution. So you can for example use WSL2 on Windows with a small Linux distribution and then extract the guix binaries from the website guix.gnu.org onto there, start guix-daemon in there and use guix like

Thank you! I also tried {$R+} type R1 = 1..3; R2 = 1..4; var a: R1; b: R2; begin b := 4; a := b; Writeln(a) end. ... and that only gives me a runtime error. So maybe those t

Yes, but this example of matrix multiplication does weird stuff: {$MODE DELPHI} {$modeswitch advancedrecords} type TMatrix<T, R, C> = record fCoordinates: array[R, C] of Double; end; function mul&

`const` in Rust is for compile-time constants. In this case, the fn `std::net::SocketAddr::new` was made a const fn recently--but was a regular fn before. >that's because it never tries to modify the value That's something dif

Drag force depends on the density of the air , the air's viscosity and compressibility, the velocity of the apple, the size and shape of the apple and the angle between the apple and the air flow. Funny enough, since Newton's law

Actually, what will happen according to the C++ standard depends on the size of int . C++ is doing implicit integer promotion of integer variables with types smaller than int , and that promotion converts those values (of the operands of

It's C++. Its goal is speed over all else. So it tries to carve out space for where the optimizer can assume lots of things are true. Since they don't use anything like Hoare logic they have to get their assertions from somewhere

You mean having one ' ? It's the same syntax in Lisp, Haskell, Ocaml, Ada and VHDL.

FWIW, in Linux, this problem does not exist. Everything is UTF-8 and Python 2 would work just fine (and always did). In order to support Windows better, Python 3 introduced support for UCS-4 (or worse, UTF-16) strings (depending on a compil

eval comes from Lisp, and there, it's not textual input. You give it a quoted form (i.e. an AST) and an environment and it evaluates the form in that environment. > (eval '(display (+ 5 6)) (interaction-environment))

The frequency is the imaginary part of the Laplace parameter s (and the attenuation is the real part of the Laplace parameter s). Laplace transforms work on systems with attenuation—that’s the main advantage. Because the kind of transform w

The article is very good. However, presenting this stuff in those languages makes it so obtuse. There's a reason this is usually explained in Haskell or in regular mathematics. There's SO much noise otherwise. 3.4.1 is basically t

There are automated (integration) test rigs that run your changes that watch Linux kernel branches. If you send a patch to a Linux kernel maintainer then it will make it into their branch and then you (the author of the patch) will get emai

It would just be slow for the caller to have to push and pop (say 30) registers in general that the specific callee (and transitive callees) may not even use. Most ABI specify some registers caller-saved, some registers callee-saved (retain

A Rust panic can be caught, too. It's just bad form to do so in Rust because it's bad for maintainability to design programs like that. Rust is opinionated and very much NOT an anything goes language. There is a culture and the cu

Ideally, what Guix would want is similar to what https://github.com/thepowersgang/mrustc/ does for Rust (a compiler, not written in Rust, for Rust). So for Dylan, we'd like to have a compiler for Open Dylan,

You want to evaluate p in: p = m n If that is gonna overflow, p > SIZE_MAX. Then it would be that (by substitution) m n > SIZE_MAX so m > SIZE_MAX/n except if n = 0. In the latter case, m can be as big as

(Column|Row) Vectors and matrices are abstractions, and having abstractions that are always the same API in all of programming (not just OpenGL) would be nice. Of course making them again and again different and dumb is easier. So we got a

It depends on what you have been doing the past two years, especially around the lockdowns. I've used the time to set up an extremely nice home office in our big now-renovated apartment. It is nice here. Any regular office would be a d
