We should go more old-school and resurrect NNTP instead: Have clients that render Markdown, and servers where users can create their own access-controlled groups. Have a group where only the owner may post: That's a feed. Have a group

Depends on the benchmark. Eg at the bottom of this page [1] can be found a simple fib(40) comparison of a few runtimes. The Node time is at 2.6x the LuaJIT time, which I'd still consider in the same ballpark compared to eg the factor o

Also keep in mind that as far as performance of dynamic languages goes, all of the P* languages (Perl, Python, PHP, and... Ruby ;)) have been left in the dust by the front-runners (eg Node.js or LuaJIT). Perl used to be king a long time ago

Maybe I'm blind, but I don't see any such download link. Or did you use 2 - Dowload clojure.jar as a shorthand for 2.1 - Install Maven 2.2 - Install git 2.3 - Clone https://github.com/clojure/clojure.git 2.4

Where can I get such a clojure.jar? What worked for me was ... 2 - Download clojure-1.10.1.jar, spec.alpha-0.2.176.jar, core.specs.alpha-0.2.44.jar from mvnrepository.com ... 5 - java -cp clojure-1.10.1.jar;spec.alpha-0.2.176.jar;core.specs

On top of that, FLRW spacetime is a large-scale approximation: More realistic models should probably follow the 'swiss-cheese' approach, where local conditions can look rather different.

Drag a marker with a constant radial velocity (from your perspective) across a spinning disk. It'll trace out a curved line, so from the perspective of an observer on the disk, an acceleration must have been present. The full 3d Coriol

It's a C idiom. Some people prefer `for(;;)` over `while(1)` to create infinite loops.

The C language standard makes certain guarantees, such as no out-of-bounds array access, or no modification of memory accessed through a restrict-qualified expression by other means. If such things happen during program execution, the progr

It's forbidden by the language standard, hence compilers assume no aliasing occurs, but it nevertheless may do so due to 'non-conforming' code. In the words of the g77 manual: > Essentially, compilers are promised (by th

by cygx 7y ago
But note that that as far as I'm aware, Fortran compilers will happily miscompile code that breaks the aliasing assumptions as well. No matter which language you use, it's the responsibility of the programmer to not break these in

by cygx 7y ago
Fortran as a language had some advantages over C for high-performance numeric code (eg more restrictive aliasing rules or stack-allocated variable-length arrays). C99 addressed this.

Which is the whole point of Han unification, the argument being that whether or not a particular line in U+4ECA is horizontal or diagonal is just like that. What's the difference?
529.
by cygx 7y ago
Unicode doesn't encode ligatures except for backwards compatibility. And it doesn't encode separate variants for unified Han characters. As in, that's not an argument, just a description of the status quo.
530.
by cygx 7y ago
There are differences as well as similarities. I'm no expert, but shouldn't, say, U+4ECA still translate to 'now' no matter if you draw a particular line horizontally or diagonally? There are also some mandatory[1] ligat

Han unification was pushed through by western interests, by my understanding. Note that as far as I'm aware, the interest in question was the initial 16-bit limit of the character set and later on the non-proliferation of competing s

Bytewise access is always possible and won't violate the strict aliasing/effective typing rules. The worst that could happen when messing with IEEE floating point values that way is creating a signalling NaN (if they are available

Yeah, my bad. I missed the point of the example (ie that the size argument might be too small). I assumed the point was memset writing to padding bytes. It is indeed true that y might not get zeroed in principle (though I doubt that'll
535.
by cygx 7y ago
And I believe that's wrong. Memset copies values to bytes, regardless if they are padding or not. You just can't rely on padding bytes keeping that value. In particular, writing to a member may fill padding with arbitrary garbage

by cygx 7y ago
It's just not guaranteed to 0 out y Citation needed. As far as I'm aware, memsetting structs is perfectly fine. The problem are things like memcmp as padding bytes take unspecified value.

In your example, assuming that a million-line program is well done in its language, you'd have exactly the same complexity but now in a thousand lines, meaning that now each line does more, is more complex and changing it/underst
