The right way to override any highlighting if you don't want to edit the colorscheme file directly

Suppose you have weird taste and you absolutely want:

• your visual selection to always have a green background and black foreground,
• your active statusline to always have a white background and red foreground,
• your very own deep blue background.

Your first reflex is probably to put those lines somewhere in your vimrc:

andrwj

git clone https://github.com/juj/emsdk.git
cd emsdk
rd /s /q clang
rd /s /q emscripten
rd /s /q java
rd /s /q node
rd /s /q python
rd /s /q zips
git reset --hard HEAD
git checkout master

andrwj

  // Available variables:
  // - Machine
  // - interpret
  // - assign
  // - send
  // - sendParent
  // - spawn
  // - raise
  // - actions

NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.
