Nice summary: http://www.javacodegeeks.com/2013/04/what-is-big-data-theory-to-implementation.html
Helps to build mental bridges between traditional RDBMS-es and what is available in Hadoop's world of BigData (i.e. billions of rows of millions of columns). Keep in mind that big DB vendors are not sleeping and do have some tricks up their sleeves, while using BigData is not a piece of cake. Still, the summary is good.

Corporate strategies in the software business are in the need of a major update. Probably not just because of the cloud, but because so much has recently changed in the way software gets developed and delivered... Interesting point of view:

A short flick worth watching. Very simple, but effective analysis of what will happen sooner or later with Greece. It raises bunch of questions. But one of the most prominent is: what will be the impact? No one knows. The best statistical tools available are just imprecise models. Drawing any conclusions out of them in such a complex system as EU is futile. E.g., some estimate, 40% of Greek economy is in a shadow (as good a number as any). Italy is not very far from it. For precise and efficient Germans it is a nightmare to calculate any sort of risk: monetary or political. EUR 2 trn? Maybe. It is not even a question whether it is an accurate number. A question is whether the right kind of people will believe it is. Being global citizens, we are in for a rough ride too :-/.

I very much recommend this slideshow about icon design. It is done by a professional who used to create icons for space invaders in an era when games were played from cassette. Even if you never need to design an icon yourselves (not an easy task these days, BTW), these slides really help to understand, how to improve your UI.

Blender 2.67b and YafaRay Engine - surprisingly good combo, open source and free. This scene took me about 2 hours to smash together while learning some basics and using rusty 3ds skills. Well, that and 20 min of rendering time for HD quality with AA. I did play with Blender before, I must admit, but it has been years ago and back then I couldn't use it. I still miss a reasonable undo system, but otherwise Blender is pretty solid, including booleans, massive selection tools, extruders, bevels etc. Now, with YafaRay it is definitely in line with grown-ups. Since I know some Python, let's see if I can script something together next time I have a minute.

I always loved to spend some time on SIGGRAPH proceedings. Graphics algorithms was my passion before I switched to Java. Since then, the cool factor of SIGGRAPH grew an order of magnitude.

Ah! That's how journalists learn to write better articles.

This article makes sense to me... So, which platforms should a good mobile app support? My guess is, Apple, Android and RIM are still going to stay for a while, with Android taking on different forms, probably.
