Writing a Parallel Sort on glsl.heroku.com

Most of the shaders on glsl.heroku.com are stateless. They define a function from the screen coordinates and time to a colour. This is a very neat paradigm because it forces you to write fast parallel algorithms, but sometimes it can be

Ateji PX

I recently came across this technology called Ateji PX. Fundamentally it’s Java extended with some parallel constructs. It is really easy to learn and provides a much cleaner programming paradigm than explicit thread creation. The concept is pretty simple. You can

Parallel For Loop in C#: Part 2

In the previous part we have implemented a ThreadPoolExecutor that accepts tasks and executes them in parallel. In this part we will implement a parallel for loop.

Webapp stacks comparison update 1

We have received measurements from one of the remaining level 3 applications. It’s Immo‘s implementation based on Ruby + Ramaze + MySQL. Here are the updated results: As soon as we confirm the measurements and get the numbers for the ASP implementation we will publish the

Webapp stacks comparison

Ever wondered what is the best technology stack for building web applications? I’m sure you have. Last week my company went on a workshop, during which we tried to answer that question. I wrote a requirements specification for a simple
