29-10-2009: Put the Refrigerator Puzzle Solver online, a tool to solve

a puzzle on my refrigerator. I had a bet with my girlfriend

that I would solve the puzzle quicker than her by writing

a program instead of her trying by hand. I won.

28-10-2009: Put the Logistic Growth Simulator online, showing the growth

of a logistically growing population. A simple theoretical

the TV program Brainiac). It's about students interacting... More info can

be found at the SimBrainiac page. It's under the 'Tools' section of my

C++ Code Snippets page. Go to my Code Snippets C++ page.

29-03-2008: Some of my fans are uniting themselves on the web. To help other fans find

them, I've added some links to my fansites. Go to my links page.

27-01-2008: Updated my Music page: now it is possible to download each of my CD's in one

download! Also, I've put the cover art online. Go to my music page.

05-01-2008: Programmed a tool called 'The Pixelator'. It 'pixelates' images, or 'it

generalizes color values over a certain range'. It can be found under

30-12-2007: Some people missed the old-school version of Boenken as much as I did. So today,

I've programmed 'Boenken 2' which has some additional options: old-school

graphics, the old-school two-button controls and the possibility of setting the

friction. 'Boenken 2' can be found on my 'Games' page.

Click here to go to my 'Games' page.

19-12-2007: I had to get it out of my head, so I programmed a Rubik's Clock Simulator. I

kept it simple, so when bored you might want to check it out at my 'Games'

page. Click here to go to my 'Games' page.

16-12-2007: Today, I've programmed the simulation 'SoaSim'. It shows the spread of a

sexually transmitted disease in interacting individuals. Also, it is just plain

fun to see the individuals 'chat'. See the 'Tools' section of my

Code Snippets C++ page. Go to my Code Snippets C++ page.

13-12-2007: Added a Levend Cluedo page! Click here to go to my 'Levend Cluedo' page.

03-12-2007: Finished the new game 'Space Harry'! Dedicated to Harry, one of my favorite

I've written forty-eight songs! See Music.

30-10-2007: Put the executable of the tool 'BarbaImage' online. 'BarbaImage' is a tool to

perform graphical operations on images. After every operation (for example: threshold

filtering, edge detection, histogram equalization) it creates a new window, so you

never loose your intermediate steps. I plan to put the source online, after I've

finished my own graphical library (called Seaull). Then, I'll licence it under

GPL 3.0. Check out the 'Tools' section of Code Snippets C++ to see 'BarbaImage'.

23-10-2007: Finished the great tool called 'HomeTrainer'. It helps one to practice nouns, verbs

and/or definitions. It saves me a lot of time not having to create trainers for

everything I want to train myself. Check out the 'Tools' section of

Code Snippets C++. Licenced under GPL 3.0. Who said one cannot become a Homo

Universalis anymore?

22-10-2007: Yesterday, I've improved the code of 'Maziak' (Go to the Games page to see 'Maziak'),

so one can choose a 999x999 sized maze. So I've also updated the 'Maze' section of

Code Snippets C++. By the way, finishing a 999x999 sized maze, with the path to the

exit known, took me about ten minutes in 'Maziak'. Still, I don't know if I was

lucky...

20-10-2007: Let's see if I can get myself doing something else then programming after having

finished my new game 'Maziak'. A clone of the MSX classic! I love it, so I put it

online. Go to the Games page to see 'Maziak'. Licenced under GPL 3.0, so you can also

view my beautifull source code.

19-10-2007: Having even more time left on this free day, I've put some more tools on my page:

'Color Number Determinator' to see a color from an RGB value and 'Random Code', a tool

to generate random C++ code. So check out the 'Tools' section of Code Snippets C++!

And if in doubt, check the screenshots. All my tools are licenced under GPL 3.0.

19-10-2007: Damn holiday! Today, I've finally put my maze generation algorithm on this site, as

well as a tool to check the algorithm visually. The algorithm 'CreateMaze' can be

found under the 'Mathematics' section of Code Snippets C++. The tool 'MazeCreater'

(nifty naming, eh?) can be found under the 'Tools' section of Code Snippets C++. The

tool is licenced under GPL 3.0.

18-10-2007: Ported one of my own favorite QBASIC games to C++. Seven years ago, I called the game

Boenken, and the C++ port still brings honour to this name ('Boenken' in English would

yield 'Bonking'). Also, the game can support a maximum of twenty players! Prepare for

cosy evenings behind your keyboard with your friends. Like all my games, it is

licenced under GPL 3.0. Go to the Games page to see 'Boenken'.

17-10-2007: Added a VCL version of 'Image Rotater', a tool to rotate images under any angle.

See the 'Tools' section of Code Snippets C++.

16-10-2007: Yesterday, I've discovered a very simple cryptography algorithm! See the Mathematics

section of Code Snippets C++. And to test and use it, I wrote a suite of programs

under the nominator 'Encrypter'. See the Tools section of Code Snippets C++. As

always, the tool is licenced under GPL 3.0.

15-10-2007: Simplified the use of the music section. See Music.

13-10-2007: Added a simple new code snippet called 'Trim' to remove leading and trailing

spaces, at the std::string section of Code Snippets C++.

12-10-2007: Programmed a new tool called 'Morpher'. It generates intermediate images and writes

these to disc automatically. Licenced under GPL 3.0. Check the Tools section of

Code Snippets C++.

05-10-2007: Wrote a new RichelCult poem called 'Som Zeven'. See RichelCult.

29-09-2007: Wrote and recorded a new hit 'Organellenwals' for the fans and one of my Belcampo

school classes! See Music.

29-09-2007: Changed my E-mail adress. You can view my E-mail adress here. Try sending your

fanmail there!

24-09-2007: In the morning one can put great games made by others online, in the evening

one might create his own great games and put them online. Today, I've

finally programmed the game Reversi in C++, licenced under GPL 3.0. That's about

nine years after I've programmed it in QBasic. Check the Games section.

24-09-2007: Today I've had the great honor to put a great game by Joost van den Bogaart

online: 'Wizard Battle', licenced under GPL 3.0. See Games.

22-09-2007: Knokfighter 1! A great game! Today, I put the source code, Windows executable and

resources of 'Knokfighter 1' online, licenced under GPL 3.0. Also the future

Knokfighter storyline can be viewed. See Games.

19-09-2007: Put the presentation of 'Eukaryote' on my Projects page.

07-09-2007: Added a paper-rock-scissors simulation program, licenced under GPL 3.0. See the

'Biology' section of Code Snippets C++.

12-08-2007: All games are supplied with source code and licenced under GPL 3.0. See Games.

11-08-2007: I have the honour to add the game 'Public Toilet Manager 5' on my website.

The game is developed by Joost van den Bogaart under the GPL 3.0 licence, so the

source code can be downloaded as well. See Games.

10-08-2007: When one can rotate images, one makes a tool called 'The Image Rotater' (spelling

error intended). See Code Snippets C++.

07-08-2007: YAHOO! After 17 years of struggling, I've finally been able to create a C++ function

to rotate a bitmap under any angle! See Code Snippets C++.

29-07-2007: I've seen that when copy-pasting my code, extra empty lines are added. I've tried to

write a tool ('The Empty Lines Remover', see Code Snippets C++), but it did not work.

Adding links to a plain text file does work fine.

27-07-2007: Added Bjarne Stroustrup, Herb Sutter, Andrei Alexandrescu, Scott Meyers,

Andrew Koenig en the young Bill Gates to the C++ panel of the C++ course

I'll be giving at the Stadswerkplaats Groningen. See Courses.

Stadswerkplaats Groningen has gone to press. See the site of

the Stadswerkplaats Groningen.

17-07-2007: I did not like having a 'Code' page and a 'Code Snippets' page,

so I combined the two. See the new C++ Code Snippets

and the Texas TI-84 Plus Code Snippets page.

16-07-2007: I did not like the licence of CodePedia, so I decided to put my C++ knowledge

online for everyone to use. See C++ Code Snippets.
