Job opportunities for a graduate business engineer.

Today we had a job fair at our university. Many companies gave short presentations to introduce themselves and talked about what job offers they have and why we should apply for them. It’s a nice PR event where you get to know employees and the companies they work for. Some companies, like Accenture and Hudson, really impressed me. Accenture fosters innovation and creativity, and seems to invest a lot in developing the skills of it’s employees. Their focus towards technology sparked my interest. Hudson on the other hand seems to be an ideal place for people with international ambitions. They match job offers with resumes over the whole world.

But even Delhaize attracted quite a lot of interest from fellow students who are looking for more traditional management work. Apparently you can apply for the position of store manager after an internship of only 18 months. This job is way to narrow minded for me though.

I found it a bit disappointing that there were so many tax & auditing firms present, yet so little innovation & technology driven businesses. The companies I would love to work for would be Apple, IDEO, Intel and I guess Accenture too. If I haven’t founded my own start-up by then :-) .

At any rate, I’ve put my resume online for anyone who is interested.

The future of user interfaces

John Underkoffler, a technical advisor for Minority Report, worked on the 3D computersystem for the 2002 Spielberg movie. Today he is the head researcher for Oblong Industries, a company that develops a “spacial operating environment” named g-speak. Take a look for yourself:

If this is how future user interfaces will look like, i want one!

Mounting a Linux software raid array with lvm

I recently had a hard drive crash on my home Linux NAS box. The important files were on a software raid 5 array, but the root filesystem (with the majority of the OS) were on a separate IDE hard drive.

Only the IDE drive crashed so my important files were safe, but I needed to remount the raid array. It took me quite a while before I got that right, so I’ll share my knowledge here for you. Here are the commands needed to reconstruct / remount a raid array with a Gentoo live cd:

The purpose of the LHC

If you -like me- are wondering why CERN build the Large Hadron Collider and what they will use it for, I found this presentation by Brian Cox very fascinating and informative.



The wikipedia entry for the LHC has plenty of extra information.

Ruby 1.8 vs 1.9 group_by performance

I am working on a ruby project which has cpu intensive tasks so I wanted to see what the impact would be of using the ruby 1.9 development version. It is supposed to provide a major performance increase.

The task used in this project crunches a large amount of data using mathematical functions, array sorting/grouping and database writes.

Ruby versions used for this test:

ruby 1.8.6 (2007-03-13 patchlevel 0) [i686-darwin8.10.1]
ruby 1.9.0 (2008-07-25 revision 18217) [i686-darwin9]

A typical run would take 240sec using ruby 1.8 and 205s with ruby 1.9 without any adaptations: A ~15% speed increase!

I dug a little deeper and found that the array.group_by method was performing a lot faster in ruby 1.9 so i wrote this benchmark to test the increase.

Pictures from Canada

I uploaded most of my picture’s from our vacation in Canada.
As always, you can find them here.

Our trip started in Vancouver on July 4th. We visited Vicatoria, Tofino, Whistler, Clearwater, Jasper, Banff and Canmore. Tomorrow we’re going to Calgary for 2 days before we take a plane back home to Belgium (if Belgium will still be one country that is).

Six word stories

Wired magazine asked 33 writers and 5 designers to write 6-word science fiction stories.

I laughed so hard with this one:

Dinosaurs return. Want their oil back.
- David Brin
