The LPI practice exams on PenguinTutor are now fully updated to the current LPI exam guidelines. The Linux Professional Institute updated the objectives in 2009. At the time I went through validating the questions on PenguinTutor.com were still valid, but it looks like I didn’t make all the changes required. Most of the questions are […]

This is a book review of a book for artists. The review is being written by someone that is not much of an artist. You need to keep this in mind when reading this review.

I have recently been having a go with the Processing programming language. You can see my first attempt in the Interactive Diode circuit demonstration – Processing / Java applet on PenguinTutor.com. I really do like the language. It was ideally suited to the applet that I have created and I hope to add a few […]

I have changed the copyright rules for the First Aid Quiz printable questions. I have relaxed the rules to make it easier for the questions to be incorporated into a commercial training session as this is something I have received enquiries about in the past.

Processing includes an IDE called the Processing Development Environment (PDE), but the editor is quite basic. The IDE has an option to use an external […]

I’ve now completed a major reorganisation of the PenguinTutor web site. This is the most significant change to the site since it was launched in 2006. The first reason for the change is to reorganise the content. Although it appeared to make sense at the time some of the categories were not as logical as […]

I have already qualified as Advanced Level Linux Professional (LPIC-2) through Linux Professional Institute Certification (LPIC), which now gives me free certification from Novell. If anyone has already qualified to minimum […]

Practical Arduino is not a book for complete beginners, but it still starts off quite gently. It does assume that you already have an Arduino and have figured out how to create a sketch and push it to the Arduino. This is not a huge step as most of the info is on the Arduino […]

Although knowledge of the command line is not required to use Linux sometimes it can come in very helpful. renaming files is one area where it is often quicker and easier to batch rename a number of files using a command line program or short script.

Dropbox provides a folder on your computer, which can be shared across multiple computers, across multiple operating systems, across the Internet or a LAN. If you ever need to access your files across multiple PCs then you need Dropbox! I was a little sceptical when I first heard of Dropbox. My first thought was that […]
