¿Qué patrón sigue la siguiente secuencia de números?

5 – 4 – 2 – 9 – 8 – 6 – 7 – 3 – 1

Los números están colocados por orden alfabético.

cinco – cuatro – dos – nueve – ocho – seis – siete – tres – uno

La película presenta más enigmas matemáticos todos muy conocidos y sencillos. Sin embargo, siempre es interesante ver películas en las que aparecen las matemáticas.

Saw this video at a friend’s place. Simply hilarious.

Never heard of Big Dog? Check out this video for reference and visit the website of Boston Dynamics for more info.

If you have any trouble sounding condescending, find a UNIX user to show you how it’s done.

I’m happy to inform you that this website is carbon neutral. And I didn’t even have to do anything for it. Happens that the hosting provider where I host this site became green by compensating for its CO2 emission via the purchase of trees from Cleanbits.

Just got my grade back for a course I recently finished. The course was about business rules and how to formalize them in relation algebra so that they can be executed by a rule engine. I noticed a lot of similarities between business rules and expert systems and I wonder if it isn’t just an old concept with a new name. Interesting nonetheless though.

Updated eduroam settings for the nokia 5800

aswin — Fri, 27 May 2011 16:44:43 +0000

In my previous blog entry I posted the settings for connecting to the eduroam network at the University of Groningen. Since yesterday however the security standard and the authentication method of the wireless network have been updated. To continue being able to access the eduroam network using your Nokia 5800 (and similar models) the settings as shown in the screenshots must be entered.

Make sure you delete any settings for the RuG-FN2 network which has been merged into the eduroam network. Also replace any username/password settings with your own.

Thanks to Willem Koster for figuring out these settings.

Eduroam settings for the Nokia 5800 at the University of Groningen

It took me a while to figure out how to connect my Nokia 5800 phone to the University of Groningen’s eduroam WiFi network. I’m posting the settings here for anyone interested.

First of all you need to install a certificate file onto your phone. Just copy it to your phone’s SD card and open it using the file manager, or browse to this webpage and download the file directly. Say yes if your phone asks if it should install the certificate. You can grab the file from here.

After installing the certificate, goto Settings, Connectivity, Destinations, Internet.

There you can add new access points. The University of Groningen uses three WiFi networks, eduroam, Eduroam and Rug-FN2. They all use the same settings. The settings should look like the ones in the screenshots below. Make sure you substitute the username with your own.
