Actually, the title of this posting is bit inaccurate… There is no vs. when it comes to operating systems. All there is is an and!

Almost every day I run into people who are… narrow-minded, for the lack of a better word.

Narrow-minded, because they approach the whole thing backwards. They first set their mind on a specific OS, and then they look at what the options are to deal with the project at hand.

Wrong, wrong, wrong…! You first look at what the best way is to deal with the situation at hand, and then you use the operating system that application runs best on!
Both Microsoft Windows and Linux (and Mac OS X, OpenSolaris, IRIX, etc etc) have their strong and their weak sides.
However, if I were to start summing them up here, this posting would…

So the next time you have to make a choice on the right software for a project, look at your resources (budget, hardware, etc) and then first find the right application for your needs.
Once you have that, there is a good chance it simply runs on only 1 OS.
If this is not the case, then and only then, you can start making operating system choices.

Apple, Linux and Microsoft
And don’t worry about ending up with a mixed environment. I know from long experience that in quite some cases Microsoft & Linux talk better together than Microsoft & Microsoft, or Linux & Linux for that matter. :roll:

To sum up: Computers and operating systems work well together, so you can and should go for the best of both worlds.

(It’s not like the whole Star Trek vs. Star Wars discussion where there is a clear winner) ;-)

Well, I can now finally answer the question I asked myself in an earlier post, about what it would take for me to switch jobs.
The answer turns out to be… location, location, location! Last week I got a job offer from Omnicom AS in Sarpsborg. The offices of this company are located 15 minutes walking from my house. Quite a difference from my current situation where I spend about 3 hours a day between house and office.

I have worked with/for some of the people there before, in my days at Respond AS, back in 2000-2002 and I guess they were satisfied with the work I did back then! ;-)

It will be a bit of a switch, from the current Linux-based R&D environment to a Microsoft-based production environment, but that is a challenge I’m up to!

I’ll be starting my new job as ‘IT-sjef’ on September 1st.
