on: Fun with compute shaders and fluid dynamics
Thank you for the kind words! Your simulation looks fantastic. I am frequently amazed how compact fluid simulations can be in practice. Definitely something I am going to aspire to reproduce on my own.

on: Fun with compute shaders and fluid dynamics
(Author here) Thanks for the interesting links!
I agree that there is much that could be optimized. The choice to use vertex buffers was driven by the overarching goal of implementing the whole thing in GLSL. It really is just a small playground project to generate some nice visualizations. If we wanted to actually use the results beyond displaying them the tight coupling between simulation and rendering would certainly become a hindrance.
CUDA usage as you describe definitely seems to be the way to go for larger scale stuff. i.e. most GPU-based LBM codes that are actually used in research seem to be based on it.

Please stop generalizing people using their nationality.
I am a German and I certainly do not agree with your views.

on: Introducing Neo900
I don't have any experience with Nokia devices other than the N900 so I can not comment on the N770. But I remember reviews from the time the N900 was released were the touchscreen was not really praised but commented on as much better than other resistive screens.
Also there are 4 years between the N770 and the N900. There is definitly no glare on my N900 screen - to the contrary, it is readable even under direct sunlight (without any backlight) because it is transreflective.

For someone who is still using the N900 as his main phone this is a great development. Altough the Jolla phone promises an equally open stack it sadly lacks the harware keyboard.

That is simply not true in my experience. The N900 screen is neither blurry nor barely responsive to finger touch. But the hardware is / was not the most interesting point about the N900 anyway.

on: Ubuntu Edge is dead, long live Ubuntu phones
This. I really would like a small netbook type ARM device which runs a normal Linux distribution and doesn't cheap out on battery capacity. The Samsung ARM Chromebook comes near but it could have a better display, casing and keyboard (ideally with a trackpoint).

on: Jolla’s first batch of Sailfish smartphones is fully booked
Same here - but I hope that Jolla can produce a viable N900 replacement for the future. It seems to be the only Linux based Smartphone platform currently in development that offers and is based on a "normal" Linux environment.

on: German Federal Prosecutor's office gets involved in the NSA data scandal
The government may publicly take a stance against the NSA programs but in reality it not only wishes to, but is actually implementing simmilar programs in Germany (see "Bestandsdatenauskunft"). I doubt that any real action will be taken.

on: My £60 ARM server
I think so too - you normally don't need wifi etc. on such a device. The one I use is the original first one and I wouldn't use the newer ones. If I remember correctly they even need active cooling...

on: My £60 ARM server
I also use a small ARM server (SheevaPlug) since about two years and it can hold up easily to VPS hosting. It runs everything I would run on a "normal" server (Lighty, Dovecot-IMAP etc.), but needs nearly no power in comparison.

on: Do you host a web server at home?
I host my Blog on a SheevaPlug from home. Additionally it runs an IMAP Server and some development stuff. In combination with the ARM Port of Archlinux it works pretty well - even with the small uplink my 2Mbit connection offers.
