Operating Systems: Design and Implementation


My first introduction to large scale development.

When I was 16 years old I borrowed this book from our neighbor next door. I brought it on vacation in France, and still remember the smell of fresh cut grass when I was reading this book in France, over and over again. The Appendix contained the entire source code of Minix.

Years later when I did my Master’s Degree in Amsterdam I followed two courses by the author, Andrew Tanenbaum.

Book details:

   Operating Systems: Design and Implementation by Andrew S. Tanenbaum.
   I read this book in English.

   This book is one of my all-time favorites.

Design Patterns: Elements of Reusable Object-Oriented Software


In my first job at Chess patterns where just coming in fashion in the mid-1990’s. Can’t say that the GoF is a book that’s great to read but it has a wealth of knowledge distilled.

Book details:

   Design Patterns: Elements of Reusable Object-Oriented Software by Gang of Four.
   I read this book in English.

   This book is one of my all-time favorites.

Disabled Windows XP beep


It’s 2010 and I’m still using Windows XP, and I’m actually quite happy with it.

One of the small annoyances is the ‘beep’ that sounds when you change the volume. Since it’s a quiet Saturday morning and the snow is impacting some of the plans we had I googled for a solution. has the answer I was looking for.

Invoking a single Ruby test


I usually run my unit tests in Eclipse on my development system, or from the command-line on the target environment in bulk.

Sometimes though it’s useful to run a single unit test from the command line. There are two equivalent ways of doing that:

rake test=test\integration\firmware_upgrade_test.rb
ruby test\integration\firmware_upgrade_test.rb

Presentation on 3D virtual worlds


Tonight I attended a presentation on the use of Second Live and other 3D worlds in education. It wasn’t earth-shattering but it was an informative presentation. Bill Krebs, the presenter, clearly enjoys using these tools and it was fun to hear more about the community in Second Life and some of the pro’s and con’s of using such tools for business purposes.

It’s always nice to go out and meet other engineers. I spoke with someone who started a company to provide data for tools like Layar, the augmented reality browser, and other interesting folks. I won a book in a raffle, and I choose Beginning Scala by David Pollack.

The evening was organized by the Agile RTP group and hosted by Allscripts in North Raleigh.

Building Flex with Maven


Tonight I attended a presentation by Adam Parrish on the use of Maven in building Adobe Flex & Java projects.

Maven is routinely used to build Java-only project, but this presentation talked about using the Flex Mojos plug-ins to build projects that combine Flex front-ends with a Java back-end.

It was an interesting presentation/demo for a small but knowledgeable crowd. There was a a lot of opportunity to ask questions, and I learned more about large scale Flex projects. A well spent evening.

The evening was hosted by One Cow Standing in Durham. They have a foosbal table and a real beer tap with Yuengling in the conference room.

Books on a phone


The Mobi Reader on my phone.When we visited a museum in Washington three months ago I saw the Kindle for the first time in real life. The Kindle is a hand held device for reading books, connected to Amazon’s bookstore. I’d like to be able to read books digitally, but $399 is way too expensive and I don’t like to be “locked in” to Amazon’s bookstore.

I read newspapers on my phone every day. The screen is fairly small, but it’s certainly readable and the other day I found out how to read books on my phone as well. I’ve started reading a classic a few weeks ago, The Brothers Karamazov, and in addition to the hard copy I now have the entire book with me where ever I go.

I installed “Mobipocket” on my laptop and cell phone, and downloaded a free copy of the book from Project Gutenberg. It’s free since the copyright on the book has long expired. It works great! Obviously, reading a physical book is still a lot nicer, but if I have some time to kill and my phone with me, I can now continue reading my book.

Canceling a Windows shutdown


Virus.One of our computers got a virus Thursday night. Of course we have virus scanners and malware scanners, but somehow this one slipped through the cracks. We were able to track down the source of the virus, an infected website.

Our virus scanner (AVG) did not fully protect the computer but it did find the originally infected HTML file. I used the excellent HijackThis tool to manually clean up the resident processes and start-up tasks of the virus.

The symptoms were as typical as they were annoying: errors on Windows start-up (“Services and Controller app encountered a problem and needed to close”) and an slow and unstable system. This time something else happened also: Windows would automatically shutdown after a 60 seconds count-down.

I learned this trick: to cancel a pending shutdown run the following command.

shutdown -a
