Testing JavaScript with various frameworks and sharing them

In an experimental state of your new solution there is often a phase where you don't know how to solve a problem in JS/HTML in the best way. The set up that is required localy is often complicated because of including of all necessary libraries and the testing is often a very monotonous repeating of adding of files.

How to use Google Advanced Search?

Everyone of use knows Google. It would be pretty surprisingly if somebody did not. When you first go to www.google.com, you don't see much. It looks like a very simple search engine. In actuality it is, but it can be used for much more. You most probably have any idea how to use it for finding the exact information. There are some tricks which I will show you in my solution part. In the right down corner, there are three links: - Advanced Search, - Preferences, - Language Search. We will work mostly with them.

How to implement a secure session management system in PHP (and generally)?

Developers, especially unexperienced PHP developers, have a tendency to not care much care about security-related issues. This is true for the problem of secure sessions, too - and the reason why attackers of a certain website or service can easily hijack sessions to get access to data, which they should not have access to. Because HTTP is a stateless protocol, sessions are required to identify a certain client on multiple requests.

Quick installation of version control for linux

You need an easy version control for Linux? Okay, it's clear that everything could be executed from the command line but why not use a graphical tool if available? Maybe it integrates nicely into nautilus the standard file manager for gnome linux systems?

debugging a node.js javascript application

With node.js internet applications can be developed in a quick manner. The programs are written in javascript. They do not run on a web server. Programs are server-side javascript applications. The bigger your application gets the more tools one wishes to have for debugging (setting break points, step through/over parts of the code, etc.).
