c - "GNU libs vs Gnulib vs Gnome glib" confusing -


i little confused these terms developer , user points. example, on ubuntu.

  1. gnu libs(https://www.gnu.org/software/libc/) installed default, gnulib(https://www.gnu.org/software/gnulib) not, right?
  2. gnu libs follows posix stadard, but: http://www.gnu.org/software/libc/manual/html_mono/libc.html#posix-threads , looks like, example, pthread_create not implemented here , implemented in gnulib, right?
  3. gnome glib 3rd library, right? based on gnu libs or gnulib? there other similar libraries?

thanks.

1) "gnu libs" means me "programming libraries part of gnu project".
gnu project not make single program, many things, , there many libraries independent of each other in it.
first thing linked standard runtime programming language c, not euqal gnu libraries in general. if installed default depends on os.
called gnulib helper thing used in other gnu programs/libs, of no use alone. makes no sense install anywhere without program, , program uses contain without need install separately (at least packet dependency etc.). again: if installed depends.

2) whether lib folllow posix or not not same being part of gnu. again different things. posix compatibility standard different operating systems (relevant libc, many others not), gnu collection of software etc. , pthread own thing, not part of gnulib.

3) glib different thing, right; not part of gnu. uses gnu libraries (which may use gnulib themselves) and/or gnulib (it´s not forbidden use outside of gnu). make sure, @ code. , of course there more programming libs...

javascript - RequestAnimationFrame not working when exiting fullscreen switching space on Safari -

request animation frame stops working when exiting fullscreen clicking on original space's safari window. fine if fullscreen mode canceled escape key or calling cancelfullscreen(). steps reproduce: open https://dl.dropboxusercontent.com/u/769042/prezi/safari-fullscreen.html click "draw raf", kittie appears click "fullscreen", go fullscreen click "draw raf", kittie appears go space original safari was, showing "click exit fullscreen mode", click anywhere, out fullscreen click "draw raf", nothing happens what handling click calling: window.requestanimationframe(draw); which draws on canvas context: function draw() { ctx.drawimage(img, math.random()*500|0, math.random()*400|0, 100, 100); } i checked .hidden , .visibilitystate, updated correctly. tested on osx 10.9.3, safari 7.0.4 (9537.76.4). has workaround/solution other switching old settimeout? this sounds webkit bug 88940 : using reque
