Hey there! Thanks for visiting my website. I just wanted to inform you that your browser might warn you about possibly malicious content if you try to download my software. This is just because you're downloading executable files. I promise there is no harmful code in any of the published applications. Also, this site does use cookies. If you continue to use this site, you accept the use of them.


Since it's understandable that you might not want to run any executable without knowing what it does, I developed TESM.TESM stands for ThrownException's Security Manager. Using a Security Manager is an already known mechanic in Java, but there is only one default one and it's static. TESM is a dynamic Security manager, with a whitelist, a blacklist, a default option and user interaction. Any code ever written eventually uses certain core methods that come with the installation of Java. These methods all consult the set Security Manager to get permission for doing certain things. Web applications won't get permission from the default Security Manager to access files for example. TESM will grant or deny permission based on a configuration file that can be found in the same folder as the executed .jar file. To set TESM as your security manager, drop the two files provided below in any .jar and run the .jar using a command line interface with:"java -Djava.security.manager=TESM -jar [name of file].jar"You can find the necessary files here.

21 Console Game

Updated: Aug 11, 2018

A console version of a well-known game.

Start at a number, increment with little steps (1-3) at once and force the other to touch the critical number (21).

Since the game is so easy to play with another human (just start yelling numbers at each other),

I made the user play against "the computer".

If you play for a second time within the same session, the game will randomise it's parameters from then on and challenge you again to something a little bit more difficult.
