There are several icons you can set on an Android notification: small app icon and a large optional icon for the body of the notification.

Read and write to spreadsheet in Java

I was writing an algorithm that would run and produce some results. These results should have been stored some place and retrieved during next program run. New values would then be added to the resulting list. The program needed to remember all the results from all run.

Btrfs filesystem cheatsheet

Btrfs is a relatively new 5th generation filesystem, similar to ZFS. For more information about those generations and filesystems, read this article over at Ars Technica.

Most difficult thing in videogame development

I’m writing this post mostly as a reminder to me and my coworkers at Studiofreya that we are not alone at struggling with video game development. Today I’ve noticed a tweet by famous Hobby Game Dev that was just about this topic. I’m gonna take answers to his question as a ground stone for this post.

CEGUI tutorial: Cyrillic Russian fonts

We were planning on going to Steam Greenlight with our game “Burnt Islands” and decided to have more than just “English” language in the game. As we’ve built our own engine it was not so difficult to implement several languages. The solution (and the problem) was CEGUI. It has support for different languages and UTF fonts, but to figure out how to make it work was not so easy.

Debug triangles in Bullet Physics

In our game “Burnt Islands” that is a heavy physics based game in a dynamic world we needed to make physics shapes of the objects in the scene. We use Irrlicht graphics engine in the game with “Bullet physics” as a physics engine. In a previous post “From Irrlicht mesh to Bullet Physics mesh” we described how to make a physics mesh from a graphics mesh.

Triplanar terrain texturing with GLSL

Stretched textures on vertical triangles is one of a million possible bugs when texturing terrain with shaders. To fix it we need to recalculate texture coordinates in 3 projections: x, y and z.

Performance testing in C++

While developing a message-driven system we’ve come to a problem of what type of object creation/destruction uses less system resources: stack or heap. And although you maybe know the answer it’s always interesting to measure to be sure. We’ve done it with the help of unit-testing.
