Recently I wanted to modify a project, to wrap a javascript function, so that I could extend the functionality of that function without breaking the project it was assigned to.

After searching the web for a bit, I found this stackoverflow-post, which exactly fits my needs. Works perfectly and I also learned something new :).

Suppose the function looks something like this:

foo = function(arg1, arg2) {
    console.log('original function');
}

now you want to wrap that function, you do this:

Regular expressions can come in handy when you need to find strings. This Regual expression simply matches relative paths. It’s not perfect, but it gets the job done :)

(([^\./\\:*?<>|"]*)(/[^\./\\:*?<>|"]*)*/([^\./\\:*?<>|"]*\.[^\./\\:*?<>|"]+))

I should mention, that this regex is meant for python and also the relative path has to have a file ending. This means that, for example the path ‘path/without/filending’ doesn’t get matched by the regex, but ‘path/with/file.ending’ does.

Update:

^(\/?[^\/]+)(\/[^\/]+)*\/([^\/]*\.[^\/]+)$

This is the optimized version :) - a lot shorter. Check this site for trying regular expressions.

After rooting my android device, I realized, that there are a variety of apps which are very powerful if you have a rooted device. In this post, I want to introduce you to my favorite apps which are only for rooted devices or are more useful on rooted devices.

Voltage Control

This simple app allows you to change the CPU govenours, IO shedulers and the CPU frequency. It does not have profiles and all this “if screen turned of then…” stuff which is, in my opinion, positive in any way. Additionally, this app is completely free and has no advertisement what so ever.
