For one of my projects I was looking for a router that runs OpenWrt. But the all time classic of these type of routers, the Lynksys WRT54GL, is definitely too expensive in my opinion and so I searched a for a cheaper alternative. And I found it.
The TP-Link WR703N is a really small router, which can be powered by USB and also can be flashed with OpenWrt.
An unbeatable argument for the TP-Link is in my opinion the price. So I think you will rarely find a new OpenWRT compatible router for less than $20. I bought mine on eBay for ~22$ including shipping, but at the moment the US prices are a little bit lower. I also added some pictures from the unboxing at the end of this blog post.
Where can I buy the TP-Link WR703N?

Wunderlist Logo Wunderlist is a tool for task management, which I use regularly. However, since I generally prefer native applications to web-based, the Wunderlist software also got it’s place on my Linux Mint system.
Unfortunately, I couldn’t find the Wunderlist client in Linux Mint’s software center, so I tried to install it manually, which ended in a big fail.
After intense googling, I found the a script on Pastebin and changed it in 03/2013. Although this was initially written for Ubuntu, it works fine under the Linux Mint environment.
For installation you just need to save the script in a file with the extension “. sh” and execute it in the shell by help of the following two commands.

sudo chmod +x installationsScript.sh
sudo ./installationsScript.sh

Linux Mint/Ubuntu Wunderlist installation script

#!/bin/bash

HttpWebRequest Logo Those who work with the. NET framework and occasionally used the HttpWebRequest class, may have stumbled about the phenomenon that it seems to be quite slow in some cases. Especially if you use HttpWebRequest in combination with threading to get responses as quick as possible, the HttpWebRequest class quickly becomes a party pooper.
Initially you might assume that the problems rely on the Internet connection, but at least after a speed comparison with wget or curl, you should recognize that the “problem” must be at the. NET implementation.

1. Increase DefaultConnectionLimit
All instances of the HttpWebRequest class are using some properties of the ServicePointManager. One of these porperties of the ServicePointManager is the “DefaultConnectionLimit”. By default, this […]

ati hd 5470 treiber Some time ago I wanted to play all the old PC games from my childhood, such as Star Wars pod racer, Need for Speed 2 and all the other great games. So I searched for the box with the old CD-ROMs, placed the first best into my laptop’s DVD drive and had to recognize that it neither run on Windows 7 nor on Windows 8. Not even in compatibility mode.
But as I did not want to give up so fast, I picked out my old Windows XP CD and installed it parallel to Windows 7 on my Acer Aspire 5740G. Unfortunately, I was reminded that you may forget to play with the standard Windows graphics drivers after the initial boot into XP.
So I started to search for a […]

Meanwhile I’m going three tracks on my laptop. This means concretely – Windows 7, Windows XP and Linux Mint 12 are bid me welcome every time I boot my laptop.
After installing Windows XP, however, I was faced with a blue screen and the following error message at the first boot:
Stop: 0x0000007B
I was on the point of doing to install XP again, when I found a solution which is much more convenient. In the BIOS of my laptop the SATA AHCI mode was set. Switching to the IDE mode brought the desired success. XP simply isn’t delivered with an AHCI compliant driver.
