Gears of War 2 – how to fix the installation problem on the XBOX 360

Borrowed Gears of War 2 from a friend to give it a whirl, and ended up confused. When I tried to install it like usual, the XBOX kind hung up (well, couldn’t get out of the install screen and no progress). After a bit searching around, and getting annoyed by all the guides focusing on pirating the game instead of addressing my problem I finally found in the xblsenioren.de forum the suggestion: “Cut the internet connection (or just log out of XBOX Live), and then install it”. I first thought they must be joking, but heck it solves mysteriously the problem with the Gears of War 2 installation. Its currently installing like nothing ever happened, weird error.

ColorHug – A open source display colorimeter

Picture of the ColorHug attached to a screenToday I read in the current issue of the Linux Magazin about a opensource colorimeter named ColorHug. It’s certainly something nice since first of all its opensource and also its noticeable cheaper then professional ones. Another plus point for me is that it works on Linux. Many probably wonder “What the heck is a colorimeter to begin with and why does it bother me?”. Well it’s not too complicated, a colorimeter is a device allowing you to calibrate your monitor so it shows the colors accurate. And why should you care? Since you want to view your pictures/videos even nearer to reality, and also it helps when you edit them. The ICC profile that gets generated by it can be used with Linux (well, to be expected, eh?), Windows and also Mac OSX.

The ColorHug itself is a small accessory with the dimensions 32mm wide, 43mmm tall and 21mm deep. It gets connected via USB. Here are some pictures from ColorHug’s website to illustrate how it looks.

The ColorHug is a lot faster then similar products and the good point is it’s open design, which allows for example picture or video editing software to integrate it.

Currently you can preorder the ColorHug for just £48 (56,57€ / 74,92$), its a 20% developer discount since the ColorHug probably have some bugs in the beginning. But due its open design and the possibility to upgrade firmware it no problem to fix possible problems later. If you order later the price is supposed to be £60 (70,70€ / 93,65$), so I suggest if you’re intrested, preorder now.

Please be aware that there are no OSX/Windows driver, users not using Linux can use the LiveCD or the Software included in Fedora 16 or later. For ordering and even more information please visit the ColorHug website.

The software and the firmware for ColorHug can be found on https://gitorious.org/colorhug.

Finally working eMail

Laptop with a opened envelope on the screen that has written eMail on it.After ages I finally took on the fight with my fear of mail-servers and got it working. Found a nice guide on Linode.com that was a great help to figure out various things. I optimized it at some points, and thanks to the book “Das Postfix Buch – Sichere Mailserver mit Linux” (german) from Peer Heinlein I did manage it. Now its adding more features like spam-assassin, virus-scanning, and more. But yea, I’m happy that I conquered my fear, but yea, I’m quite unhappy with the documentation of the dovecot/postfix. It could be improved a lot, but sadly I lack (yet) the knowledge to do so. Without that guide I certainly would have run into a bit trouble, since some points are a confusing without a hint how to work with it. But yea, made it and I will blog also about how I implanted the upcoming features, so you guys can also use it if you also think on setting up a mailserver.

Helpful tools for checking your mailserver are these:

abuse.net/relay.html Mail Relay Testing -Check your mailserver if it can be missused as a open-relay to send spam.

www.mxtoolbox.com Various tools from check your domain’s mx record to checking the servers SPF response.
