Loadbalancing owncloud with HA Proxy

This post shows more advanced loadbalancing for owncloud service. The primary concept is inspired by owncloud with dedicated php-fpm service post.
This architecture is more advanced and provides better scalability for load division and therefore better performance.
Performance is crucial factor for such a service providence and a single Raspberry Pi doesn't have much of it. This architecture (2 loadbalanced Raspberry Pi's) provides 33% performance increase and offers easily to connect more nodes.

Custom i3-status bar and SLiM configuration

In this post, I'll show how to change theme and other configuration for SLiM login manager, how to setup conky to create customized i3-status bar and at the end I'll cleanup old unnecessary KDE packages, no longer needed in i3.

Replacing KDE with i3 and basic i3wm setup

Bash Specialities, part 1

This post shows some more or less frequently used features in bash, which might come handy in some situations.

i3 window manager

Not long ago, I've switched from KDE window manager (kwin), which I've been using for years, to tiling window manager i3. So far I've tried several different WMs but none has suited my needs perfectly, until now.

What do I expect from window manager:

• it should be highly customizable. It should provide ways to set keyboard and mouse shortcuts. In this way, kwin has been really great and that was the main reason I was using it.
• it should be lightweight. This was the main issue, which kwin and KDE desktop had. On the other hand, i3wm with Slim is very simple and lightweight.
• it should be fast. I don't say kwin was slow, but in comparison to i3, well, it is (:
• eye-candy... yes good looking windows are sign of a modern WM, but for me eye-candy isn't very important.

In this section I'll post how I've replaced Kdm and kwin with Slim and i3 and I'll show my configuration of i3.
