Streaming your Linux desktop to Youtube and Twitch via Nvidia's NVENC and VAAPI:
Considerations to take when live streaming:
The following best practice observations apply when using a hardware-based encoder for live streaming to any platform:
Set the buffer size (-bufsize:v) equal to the target bitrate (-b:v). You want to ensure that you're encoding in CBR mode.
Set up the encoders as shown:
| #include <exception> | |
| #include <functional> | |
| #ifdef __EMSCRIPTEN__ | |
| #include <emscripten.h> | |
| #include <SDL.h> | |
| #include <SDL_image.h> | |
| #include <SDL_ttf.h> |
I fell in love with CoffeeScript a couple of years ago. Javascript has always seemed something of an interesting curiosity to me and I was happy to see the meteoric rise of Node.js, but coming from a background of Python I really preferred a cleaner syntax.
In any fast moving community it is inevitable that things will change, and so today we see a big shift toward ES6, the new version of Javascript. It incorporates a handful of the nicer features from CoffeeScript and is usable today through tools like Babel. Here are some of my thoughts and issues on moving away from CoffeeScript in favor of ES6.
While reading I suggest keeping open a tab to Babel's learning ES6 page. The examples there are great.
Holy punctuation, Batman! Say goodbye to your whitespace and hello to parenthesis, curly braces, and semicolons again. Even with the advanced ES6 syntax you'll find yourself writing a lot more punctuatio

| Fixed point arithmetic | |
| A fixed point number is an alternative representation for a real number. | |
| IEEE floats, `f32` and `f64`, being the standard format in processors with | |
| Floating Point Units (FPU). You should consider using fixed numbers on | |
| systems where there's no FPU and performance is critical as fixed point | |
| arithmetic is faster than software emulated IEEE float arithmetic. Do note | |
| that fixed point numbers tend to be more prone to overflows as they operate | |
| in ranges much smaller than floats. |

| Version 1.1 | |
| Note that iBooks actually uses internal JavaScript to set the "__ibooks_internal_theme" attribute on :root (html) element | |
| every time the theme is changed, but this happens independently of whether your epub html markup is scripted or not. | |
