I was looking into custom WordPress theme tutorials when a friend of mine pointed out this tutorial. It is very well written and covers the following topics:

• Creating a Theme HTML Structure
• Template and Directory Structure
• The Header Template
• The Index Template
• The Single Post, Post Attachment, & 404 Templates
• The Comments Template
• The Search Template & The Page Template
• The Archive, Author, Category & Tags Template
• The Sidebar Template
• Reset-Rebuild Theme CSS & Define Your Layouts

Quite complete, and definitely enough to get started in developing your own WordPress themes.

• Analyze, display and filter packet trace files.
• Supports PCAP packet capture format.
• Quicklook plugin included – it is basic but at least you can get an overview over packet trace files in finder.
• Intel 64-bit CPU support.

It turned out my Ubuntu server does not start Subversion automatically on boot. I found this website with instructions how to create a startup script.

Create a file called “svnserve” in the /etc/init.d folder

$ sudo nano /etc/init.d/svnserve

Add the following line to this script in order to start the Subversion server:

svnserve -d --root /srv/subversion

Save the file (CTRL+O) and exit nano (CTRL+X)
Now make the file executable

$ sudo chmod +x /etc/init.d/svnserve

Add the svnserve script to the init.d boot sequence

$ sudo update-rc.d svnserve defaults

Now you’re done! On the next reboot the SVN server will start automatically.

I noticed that I connect a lot to my server in order to retrieve files, so I thought it would be useful to connect through NFS instead of Samba. Installing NFS on my server was a piece of cake. Just follow this tutorial and you are done.

The only thing you need to do then is manage your shares in the /etc/exports file. So far so good. But when I want to connect I receive an error which tells me I use the wrong username and/or password. Funny enough the whole system did not even prompt for any of these credentials.

I accidentally formatted my external harddisk in OSX. Since I wanted this disk to be NTFS I needed it to be formatted in Windows. When I opened up disk management I was unable to format the harddisk because it had a GPT protected partition on it.

In SPSS you can program datasets in the SPSS syntax language. Unfortunately a lot of people working with SPSS do not really know how to use these syntax commands. A common way of using syntax is just do a “copy/paste” but barely knowing what the code really does. In order to solve this issue these series of SPSS syntax tutorials show, and explain how SPSS syntax can be used.

This tutorial is about how to define multiline comments, numeric and string variables in SPSS syntax code.
