PySide: Rightclick Button Menu

PySide: Rightclick Button Menu

PySide ( is an awesome Framework that allows you to use Qt with Python. Installation is as straightforward as typing

pip install pyside

I will be creating a menu that opens with a right click.
This menu is called “Context Menu” in QT.
In this example the right click menu on the button removes the button at runtime.

Ubuntu 13.04: Post Install Setup

Ubuntu 13.04: Post Install Setup

After the installation of Ubuntu you want to start being productive as fast as possible. There are three things you need to do:
1. Install the Programs you need
2. Remove the unwanted pre-installed Programs (for example Amazon Integration, Rhythm box)
3. Install all System Updates

While you could use the Ubuntu Store to install all programs by clicking through various screens. You will have a great performance gain by using the console and the “apt-get” package manager.

In the spirit of never having to repeat myself, I simply collected all the console commands I needed to complete the three steps.

Your personal setup will be slightly different to my setup, feel free to modify and adjust the script to suit your needs.

General Tips

About Page

Create and maintain your about page, it is one of the most commonly visited sites on a blog.


When logging into WordPress admin area it always notifies you if new security patches are out for WordPress. Always check first if your theme and plugins work with that new version, then make a backup and then update WordPress.

Google Stuff

Google provides many different tools for WordPress. However for everything there are also alternatives (well search google you’ll find something)


This allows your RSS feed to be handled by google and in essence you could change the location of your blog and all subscribers to your blog automatically get the feed from your new location. In addition it provides Statistics how many people are subscribed to your blog.


This is one of the more creepy plugins from google, in essence it keeps track how much time people spent visiting your site, what they click, where they are from, what kind of computer they use etc.


Well Adsense is one way to make money with your blog, in essence it is a banner controlled by google and whenever somebody clicks the ad you get some money like 5cents. Well you get a check when you should get 70bucks, so it could take some time.

Personal reasons

It is always best to have your own personal reasons why you maintain a website or a blog. But always keep in mind that the site is there to enrich the internet in some way.

Be mindful that you always will receive negative comments on the internet, you can ignore them, however if they are constructive you should at least listen.

And as always remember to have fun.

A selection of themes can be found at smashing magazine:


After you have selected and installed your theme you usually define a menu for your site. In most cases you would want the user to be able to browse categories. However you also can let the site navigate to Pages or custom URLs.

To allow the user to browse categories you first have to define categories, this is found under Posts > Categories.  Whenever you create a new Post you should set a Category, if not it will be stored in the Category “Uncategorized“.

Here you set up your Categories

Here you set up your Categories

After you have set up the categories you can add them to your Menu. Important: You can set up multiple Menus, however one menu is always set to the “Primary Navigation”.

There is a Save Menu Button and a Save Primary Navigation Button

WordPress: (Part 1) Installation and Configuration

WordPress: (Part 1) Installation and Configuration

In this three-part series I will be showing you the basics of creating a simple website using the Content Management System (CMS) WordPress. By using a CMS  you can add and modify content to the the website directly in your browser even without any programming experience.

WordPress is easily extended to support various types of websites.

Part 3 Plugins:

  • General tips

Server Requirements

A website is always hosted on a server. A server is basically a computer that is constantly running and connected to the internet. When choosing a web hosting service you have to make sure that it supports PHP and MySQL.

Free Web hosting

If you are just starting out and want to test things on a server there are several providers that offer free web hosting, however you usually only get a sub-domain. These offers are useful for experimenting with WordPress however a sub-domain suggests that you are an amateur.

One of the few exceptions is when you simply want to run a blog. has blog hosting services however you only get a sub-domain.

Paid Web hosting

Professional web hosting costs money. In most cases you have to pay for the domain and the available web space. The package includes email-addresses accompanying the site.

Amazon AWS

Finding a Domain name

At this point in time the most good names are already taken or people bought the domain and just wait to sell them off.

To check if your domain is still available try out:

Or if you want a random web 2.0 domain Name:

  2. Open Filezilla and
  3. Create a new Site, and enter your ftp-access data.

  6. Go to the MySQL configuration site
  7. Create a new user (e.g. wordpress_sqlusr) with a strong password


  1. Download WordPress from
  2. Extract the files on your computer
  3. Open Filezilla, and open a ftp-connection to your server
  4. Transfer all files to your server
  5. In a Browser open your website
  6. WordPress will state that the config-file has not been configured. Click on next
  7. Enter the data asked by wordpress. Use a very strong Password to prevent anybody else accessing your site as administrator.

WordPress configuration

Now that WordPress is installed you can configure the site

  1. When you go to /wp-admin you can logon and start configuring your site.
  2. Simply Navigate on the sidebar and click on Settings. WordpressPart1
  3. You will find all Settings in this panel and all of it is very well described. Simply go through every different type of Settings.

Difference Post and Pages

A Page is a static website. The Webpage is always the same and never changes. (usually the About Page)

However one of the benefits of a blog is that it has an RSS Feed. Other people can subscribe to this feed with an RSS Reader and when you add new content to your blog they automatically get notified of the change. The blog is generated dynamically from all the posts available.

In most cases it is more useful to use Posts, but it depends entirely on your website. A simple website also can only use static Pages.
