OSX HP Color LaserJet CM1312 MFP duplex printing

December 17th, 2009

When I started to use my HP Color LaserJet CM1312 MFP it turned out that manual duplex printing was not exactly working. Page 1 had page 7 on the back etc. The problem was that the printer prints its pages in opposite direction, starting with the last page. I spend lots of time seaching for a solution. I found this website, which descibes how to change your printer driver in order to print from 1 to n. Here are the steps you need to do…

Practising pentatonic scales on guitar

November 25th, 2009

Quite some time I am playing the guitar. I have an acoustic and electric one (a black Ibanez EXR-170 for those interested). A friend of mine recommended practicing pentatonic scales. I looked up some link and started practising, this improved my guitar solo skills for sure. Here are the links I found:

Enable JSLint Javascript source code validation in Aptana

October 18th, 2009

You might know Aptana, which is a free, on Eclipse based Javascript IDE. Aptana has several nice features like autocompletion and code formatting. You might know Lint as well. Lint is a tool which checks your code from well known coding errors which do not necessarily cause weird program behaviour. It turned out there is JSLint as well, which is Lint for Javascript. The nice thing is that Aptana natively supports JSLint code verification. Out of the box Aptana uses the Mozilla Javascript Validator.

In order to change your validator launch Aptana and click Window -> Preferences. Then goto Aptana -> Editors -> Javascript -> Validation. Now check the JSLint checkbox. Click [Apply] and you are good to go. You might want to uncheck the Mozilla Javascript checkbox.

Samsung NC10 hardcase

March 11th, 2009

Last week I received my new Samsung NC10 hardcase. The softcase that came with the laptop did not seem to be that solid as expected which made me order another one. The Dutch website koopje.nl had a nice offer. For only 11,75 EUR they provided a nice looking case with foam which adopts the shape of the netbook.

Brand: Elecom
Type: 8.9″ Zeroshock III Notebook inner bag

Disable root login for ssh server in Kubuntu

February 13th, 2009

If you are a hacker, what is the thing you want to be on a Linux System? Root. You can try to access a ssh server with the root user. There is an option in the ssh server configuration which prevents a remote root login. This does not mean you can not become root, it means no one can directly login as the root user. So if you are logged in as Alice you can simple enter the “su” command to become root.

How we can prevent the remote root login is described below.
