ES module for detecting undefined CSS classes (uses mutation observer to monitor DOM changes). `console.warn()`s undefined classes.
/**
* Sets up a DOM MutationObserver that watches for elements using undefined CSS
* class names. Performance should be pretty good, but it's probably best to
* avoid using this in production.
*
* Usage:
*
* import cssCheck from './checkForUndefinedCSSClasses.js'
*
* // Call before DOM renders (e.g. in <HEAD> or prior to React.render())

How to push to multiple git remotes at once. Useful if you keep mirrors of your repo.

Pushing to Multiple Git Repos

If a project has to have multiple git repos (e.g. Bitbucket and Github) then it's better that they remain in sync.

Usually this would involve pushing each branch to each repo in turn, but actually Git allows pushing to multiple repos in one go.

If in doubt about what git is doing when you run these commands, just

Git Submodules basic explanation

Git Submodules - Basic Explanation

Why submodules?

In Git you can add a submodule to a repository. This is basically a sub-repository embedded in your main repository. This can be very useful. A couple of usecases of submodules:

  • Separate big codebases into multiple repositories.

NGINX tuning for best performance

Moved to git repository: https://github.com/denji/nginx-tuning

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.
