My understanding is that ISPC is a special compiler that takes a function and emits a SIMD function that computes the original function 4/8 times (and repeats). And it's Intel only. It might be great for some uses, but it's n

I know. I want to use them on the CPU, without having to deal with a big runtime system like OpenCL. OpenCL is still missing the vector width polymorphism. The others are more or less covered. This is a matter of language standardization an

Watching this makes me sad that there are no languages that would have first class SIMD vector types that would enable writing portable SIMD code for different CPU instruction sets (SSE, AVX, NEON, etc). The closest thing to what I want is

You're absolutely right about scanline rasterizers and GPUs, but scanline rasterization is very interesting historically. Most of the 1990s pre-GPU software renderers did scanline rasterization, for example Quake and Thief had a pure s

Yes, it's a bit ugly but it still doesn't make it useless. It could be useful for e.g. passing a comparator to qsort using a captured variable to pass the comparison criteria (e.g. compare arrays according to the n'th element

Last time I checked, Clang doesn't support nested functions although it supports most of GNU extensions (or similar features with slightly altered syntax). I'm not 100% sure what you mean by "proper closure" but it does

What kind of setup you have for KSP controllers? Do you have something for translation/rotation control for maneuvering in orbit? Two joysticks or a secondary joystick/hat in HOTAS or something?

Combat: DCS World is popular. Warbirds is still alive. Rise of Flight for WWI simming. IL-2 if you want single player. Falcon BMS for modern, detailed aerial warfare (weapon systems, radars, etc). Civilian aviation: X-Plane, Flight Simulato

Depends on what kind of flight simming you're into. If you're into instrument flying, there's not much need for decent framerates because you can't see anything but clouds or blue skies out of the window and 4 fps is eno

Word of warning about OOP: it's just a programming paradigm. It's not the best or the only way to do things, but some 1990s era educational material might tell you so.

You seem to have taken a "lesser of two evils" approach and that's probably a good idea. Side channels are not as bad as completely broken crypto, as long as the critical infrastructure (api.wordpress.com, etc) is good. If so

Here's the thing: "normal users" looking for a free-of-charge alternative to commercial apps are not the typical target audience of open source productivity tools. They're primarily targetted to scratch the authors'

Yikes indeed. Implementing crypto primitives in an interpreted language is full of hazards for side channel attacks - being constant time is just the first step. Cache behavior, branch predictor attacks, etc are also important. And all of t

Not GP but same situation. Firefox isn't always great. Start-up time is really slow, hogs a lot of memory, unnecessarily slow and sluggish and most sites are primarily engineered for WebKit/Blink -based browser engines these days.

by exDM69 10y ago
Vimium just doesn't work as well as Vimperator, which is why I use Firefox and not Chromium for my primary browser. That said, Vimperator is far from perfect and sometimes buggy and I don't need all the features (like macros).

Chains might not be what they used to be but the multi-geared sprockets with tight tolerances definitely aren't. It's cheaper to change the chains sooner than to wait until they wear out your sprockets badly enough that you can&#x
