It's not just disrupting YouTube, it's also about creating a sustainable service. Video streaming has enormous costs which you need to get back somehow. Unless your niche audience is willing to pay per minute, it is going to be di

Here's my "simple" makefile for C. It's for building a simple executable and a static library. I don't use Make for more complex projects. It has a bunch of extra features, like coverage and profiling and tags files

Put -MMD to CFLAGS and you can drop the rules to build dependency files. The compiler will then generate the deps files when compiling. Don't use wildcards in clean target. Use $(RM) $(OBJS) $(DEPS) instead.

Either you should not write it, or disable all built-in rules of Make with a flag. Doing both is asking for trouble. Make has lots of built-in rules for lots of languages, C, C++, Fortran, Lex, Yacc, etc.

The corporations in question pay very little taxes in the first place, getting them to pay their fair share would be nice. But I don't think that would change their negative influence on the society.

No, that was just spoofing the PCI VID:PID to the kernel. It did not enable hardware features, just fooled the driver into thinking it was another device. You could do the same with a patched kernel if you don't want to solder.

You can't rely on autovectorization because it's a really brittle optimization that only works at the best of times, and generally only with simple loops. For anything more complex, you need to write SIMD code explicitly. Getting

I've had success using C vector extensions in GCC and Clang [0]. With a simple typedef, you get a portable SIMD vector type and basic arithmetic operators working. It's compatible with platform-specific intrinsics (SSE, NEON, etc)

The business model of consoles is selling hardware at discounted price which is not profitable, then selling games at a premium price. All the game sales give a cut to the console company. This only works if there isn't a lot of piracy

I'm not. I do need a browser and maps. I've been considering moving to a dumb phone, but I do need some basic features.

Scaling requires interpolation, but nearest neighbor sampling was good and fast enough for old school rotozoom effect.

I think that using a series of skew operations for rotation could still be useful. Bilinear/trilinear texture lookup will always look a bit blurry. Most graphics processing apps are still done using the CPU for most basic operations. A
