How to stop bots from crawling your website
Bots crawling our website every minute are becoming a problem. They are using server resources without giving anything back.

Personal computer security threats
When I came home and turned on my computer yesterday, it acted really weird. I was locked out of my main email account. My files didn’t want to be moved or copied and the file explorer acted strange.
How to convert java long to 4 bytes data
Java doesn’t have unsigned types. In order to convert C++ unsigned values to Java you may need to use larger types. Authors of the language explain it as the Java should be a simple language and be easy to understand for all developers.
Our WordPress website keeps getting hacked
We are running several websites with WordPress in different categories – everything from blogs to online shops. WordPress is great. It is easy and powerful at the same time. Although there is one thing that gives us a doubt of the platform – our WordPress websites get hacked. Especially more popular ones.
How to protect images on website
Today, people are generally aware that you need to check the license and permissions before using the image you found on the internet. Images are still being stolen from their original creators. If you are creating professional artwork or taking good photos – you still need to spend time securing your property online or it will be stolen.
Greatest data simulations 2015
There are a lot of interesting things out there on the Internet. Here we gathered some really cool data simulations of the year 2015 that shows that Internet really is beautiful.
Synchronizing data – how easy is it to implement
In 1999, Bill Gates predicted that there will be developed devices that connect with each other and synchronize data in a smart way.
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.
Mechanics behind a game engine
We’ve worked on our own game engine (“Monster game engine”) for almost three years. It is this engine we were using to make “Burnt Islands“.
Basic primitives
Introduction
When you want to do real time computer physics, like what we see in games, you will have to break the world into understandable items. It’s like Caesar’s divide and conquer tactic. When you are playing in a complex scene, all what really goes on in the physics engine is broken into small, but many pieces. This enables further optimization down the line, which will be covered later, but for now this keeps the collision detection and collision response algorithms easy to understand.
