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.

This is a very simple application. When launched, it will create one big white rectangle on the screen and what I called a "Root Window". When you close this window, it will also make all rectangles disappear. Since each rectangle is floating freely, you can place them all over your desktop. I only put them on a white background to make a screenshot, but there isn't a background in the application.

Click a rectangle to pop it:

- Portrait oriented rectangles will be split horizontally.

- Landscape oriented rectangles will be split vertically.

- The red, green and blue values of the colour will be split into two new colours at random.

Drag a rectangle to move it.

Put two rectangles next to each other to merge them:

- The rectangles must be of the same shape.

- The rectangles must have touching edges (there is a little bit of a margin though).

- The red, green and blue values of the two colours will be merged

in the opposite way they were split.
