Installing Wubi 9.10

Posted on 2010-04-23 By rolfje 2 Comments on Installing Wubi 9.10

Why I HATE LinuxOk, fist of all: DO NOT DOWNLOAD WUBI 9.10 as it contains a serious GRUB2 problem which will give you some headaches if you’re new to Linux. Why I’m saying this? I just ran into this GRUB2 problem while installing the new Wubi 9.10. Here’s what I did:

  1. Downloaded Wubi 9.10 windows installer and ran it.
  2. Installer downloads stuff, and boots into Ubuntu installer
  3. After reboot, GRUB screen comes up with a loud beep and a prompt. Great.

Some googling finds a lot of Linux voodoo talking l33tspe4king nerds, but it did contain some info with which I managed to get things working:

Posted on 2010-04-19 By rolfje 12 Comments on Anti-fog Helmet Visor Tip

In some biker magazines you’ll see some cheap journalists write that the “dish washing soap anti-fog is an urban myth”, and that it will “blur your vision”, some may even say it’s downright dangerous. This blogpost is to show that if done right, dish washing soap is actually the absolute best anti-fog treatment money can buy. If you’ve tried this and still don’t like it, there are some easier alternatives at the bottom for your convenience.

Ibatis Inline Parameter Maps

Posted on 2010-02-16 By rolfje 3 Comments on Ibatis Inline Parameter Maps

Today I (re)discovered a feature in the Ibatis data mapper framework which was clearly documented, but for some reason was not being used in our project. The feature is called “inline parameter maps” and combined with a wrapper bean it can clean up a lot of clutter in the code and in the SqlMaps. Please feel free to share this example with your fellow Ibatis Data Mapper 2 framework users.

The rumors can stop now. iPad is here.

Posted on 2010-01-27 By rolfje No Comments on The rumors can stop now. iPad is here.

So the word is finally out, it’s going to be the iPad. I was kind of worried about this, and my worries are not completely taken away by the news currently oozing out of the Apple keynote. I see some problems with this device, although they are well hidden under Steve’s reality distortion field, the Apple secret sauce and the “gee why didn’t we think of that” features.

Kilometerheffing? GPS-data NEE!

Posted on 2009-12-24 By rolfje 2 Comments on Kilometerheffing? GPS-data NEE!

Ik weet niet welke lobbyist menner Eurlings heeft verteld dat dit een briljant plan is, maar ik weet donders goed waarom onze regering kilometerheffing wil invoeren. Weer een kraantje toegevoegd aan het vat dat “werkende Nederlander” heet, en als bonus nog wat privacy gevoelige GPS gegevens om in rond te neuzen ook. Mocht je de rest van deze post niet willen lezen, reageer dan wel even op de volgende sites, want Eurlings heeft gezegd dat kilometerheffing “bij gebrek aan draagvlak” (welk draagvlak?) niet doorgaat:

  • http://www.kilometerheffingnoway.nl/
  • http://www.kilometerheffing-nee.nl/
  • http://petities.nl/petitie/kilometerheffing-is-verkeerd
  • http://www.kilometer-heffing.eu/
  • http://www.anwbledenpeiling.nl/ <– Eurlings gaat deze uitslag gebruiken! (als je de vragen gezien hebt zie je waarom :-/ )

Why you want a Polarizer Filter

Posted on 2009-06-16 By rolfje 2 Comments on Why you want a Polarizer Filter

I recently bought a 50mm lens with a circular polarizer. I though I’d share some quick examples to show what a polarizer filter does for your photo’s.

The polarization effect is probably one of the few (if not only) effect which you can not reproduce in photoshop or any other image processing program. Most applications try by increasing saturation, which is nowhere near the effect of a real polarizer.

By rotating the filter, you have the luxury of choosing how much effect you want to have, anywhere between 0% and 100%. The shots below give you an idea what the range of the effect is:

Migrate from Password Gorilla to KeePass

Posted on 2009-05-12 By rolfje 3 Comments on Migrate from Password Gorilla to KeePass

KeePass logoI used to use Password Gorilla to store my passwords, because it can run on both Mac and Windows. Because my password database keeps growing, Password Gorilla is becomming a very slow starter, even on my new solid state disk. A few weeks ago I learned that KeePass is a much more modern application, and is available for both Mac and Windows. Here’s what I did to get all my passwords into KeePass:

LED’s in your livingroom?

Posted on 2009-03-08 By rolfje 7 Comments on LED’s in your livingroom?

In some countries, there is some talk on banishing the classic (incandescant) lightbulb. I think this whole discussion is needless. The only reason why it exists, is that the fluorescent bulbs are often of mediocre quality, and certain people are here to enforce their bad tastes upon us “for a greater purpose”.

Don’t get me wrong, I really like trees and birds around my house, and I would be more than happy to install energy-efficient appliances in my home, even if they cost me slightly more. But especially if I’m paying more, I expect to get a certain level of quality.

Because of the inefficiency of incandescent bulbs, and the number of bulbs in my household, I decided to look around for energy efficient solutions. Particulary LED lighting caught my interest, because it is not only energy efficient, it’s also dimmable with normal (cheap) floor dimmers. They even stay cold enough so that children touching them do not burn their fingers.

Are you a Wise person?

Posted on 2009-02-18 By rolfje No Comments on Are you a Wise person?

Rubber Duck

When Ducks migrate for the winter, they are able to have their brain partially asleep. This comes in handy when you have to fly hours on end in a pack, without restbreaks. Aparently, people have started to adopt this habbit. Yes you’ve read that right. I’ve seen some very good examples of people using only one half of their brains.

Tweet Week

Posted on 2009-02-15 By rolfje 1 Comment on Tweet Week

TwitterAbout a week ago, I was a bit bored and decided to see what Twitter is all about. I created an account, and I Tweeted for a week. I tried to keep to the original idea, where a Tweet should answer the question “What are you doing”? Looking back, my tweets include Coffee, Podcasts, Global frustration, Small joys, Small irritations, Re-tweets, and Replies.
