If you ever need to schedule shutdown Cool Shutdown is a piece of software you need. It is very simple - does only what it has to do. You can select between two modes: "Turn off after specified time" and "Turn off at specified time". For example, if you select first mode and enter "00:05:10" your computer will shut down after 5 minutes and 10 seconds, but if you select second mode your computer will shut down at 00:05:20 AM.

This program is useful in graph theory. For given graph it colors all connected components and finds the largest and the smallest one. Graph is determined by number of nodes and adjacency matrix where A[u][v] is 1 when u and v are connected. It has also ability to create random graph with given number of nodes. Coloring algorithm is based on DFS.

If you need to get rid of a file and make sure nobody will recover it later File Destroyer is the right tool for you. In integrates itself into windows explorer's context menu. To destroy a file you just have to select "Destroy File" option in file's context menu. Since it does not need User Interface no screenshot is available.

This simple and interesting utility will help you measure objects on your desktop. Usage is very simple - just place StormRuler next to object you want to measure and set ruler's tick to object's opposite side (like on screenshot). As you can see on this screenshot, ruler is half-transparent, so it looks very cool under Windows XP

WorkMeter is simple and funny program which measures mouse activity: It counts keyboard and mouse clicks and calculates cursor's trajectory length in pixels and meters. Calculated length depends on diagonal length so it must be set in order to achieve better accuracy. You can also analyze daily usage using WorkMeter's HTML statistics. WorkMeter can also run when Windows starts.

RAT (Remote Administration Tool) Package consists two programs . Server and Control Center. When you install Server on remote machine you can connect to it from any computer using Control Center or just Windows Telnet and you can download files, view desktop on remote computer, execute programs, chat, play with mouse, "press" keys on Server's keyboard and much, much more. Must have it. Note: in source code all encryption keys are replaced with 0 for security reasons.

Snake Charmer is one more snake clone. It features Boss Key, Top players list and level selection. Very simple and effective, if you like snake games you should definitely try it.

This utility converts expressions from Infix to Postfix (also known as Polish) notation and vice versa. For example, expression (a+b)/c+d in infix notation is equivalent for ab+c/d+ in postfix notation. Note that there are no brackets in postfix expressions. Operation priority is determined by it's position. You also get step-by-step explanation of conversion algorithm.

This small program helps you solve numerical problems with finding X in given interval [a..b] for which is f(X) = 0. You enter function and range and program will calculate X step by step saving your time. It can also narrow interval if it is possible. You can use all standard elementary functions, such as sin, cos, exp, log...and constants pi and e.

Note: Newton's iterative method uses iterative process F(x) = x - f(x)/f'(x) and sometimes cannot be used for solving this problem (for example if f'(x) = 0 for some x). Besides, f'(x) is also calculated numerically. Calculation precission is 10E-10.

This is just small application that reminds you that your tea (or coffie) water has boiled. I used to forget about it very often so I made this program to help me out :) Just enter time needed for water to boil and it will remind you with sound and message.

It is made in C# .NET so it requires .NET Framework to be installed on your computer in order to run this application.

This is small component for Delphi which measures time you are spending to develop the application. Data is saved to Registry so next time you run Delphi and open your project time will continue where you left it last time. You can pause timer or reset it to zero any time. Time is displayed in short and long formats on a Label and is working only in design-time. You can also use many different TWorkTime components on one project/form to measure time for different jobs. It's very easy to install and use. Source code is included (nothing else is necessary, though). By the way, this is my first component :)

With this program you can run and analyze algorithms written in form defined by Donald Knuth in his 2nd algorithm definition. If you know what it is you'll find it very useful, otherwise...I don't think so :) There are three to run your algorithm : simple execution and return output, step by step execution where you can follow result in every algorithm step and report.

Curve Builder draws graph for parametric functions where you set real function for each coordinate in 3D space. Drawing is isometric with 4 viewing angles - front, left, bottom and perspective. It also has Auto-zoom feature witch sets zoom ratio for best fit on screen. Interesting feature is calculating curve length, something like in "real" mathematical analysis - split segment to many parts and than calculate length of polygonal line. I used Expression Evaluator v1.4 for Delphi freeware component which can be found here.

The name speaks for itself. This is small and useful program that can replace expensive ordinary metronomes. You can set tempo to any value between 30 and 300. Program is very interesting designed and can work with either MIDI device or PC Speaker. This means that you can use Virtual Metronome without having sound card at all! In older versions this was not possible. Also, playback is now more stable and constant than before and less buggy (not buggy at all, I hope). Besides that, there are few more minor cosmetic changes (like XP visual styles support). This program can help you allot if you are a musician.

This is an old game I wrote during political crisis my country suffered during 90's. The goal is to eliminate ex president Slobodan Milosevic (who ruled Serbia during that period). You can practice on few significant Serbian politicians too and use several different types on guns. This game lost it's charm the day Slobodan fell, but it's not bad to have it...just in case :) Meanwhile I lost source code...

This is simple pastime game you definitely know. No need to talk about it much. You play against computer only. There are two difficulty levels to choose - Easy and Hard. It's very hard (but still possible) to beat computer at hard level. I started making multi player version of this game (for network playing) but at about 80% of job done I stopped. Maybe I'll finish it one day :)

With this program you can make your text look funnier, S0m3Th1n6 l1k3 th1s T3xT. It's not very useful, but you can make some fun with it. It can copy output text to clipboard or save it to text file. There are three ways to make your text weird. Randomly change case of every letter, switch some letters with look-alike numbers and invert text (for reading right-to-left).
