My first steps in java .. it was not too hard alltogether, thanks to the netbeans ide. This solver solves all of the hard (and easy, too) sudokus rather quickly. Not implemented is the search for all possible solutions (think of a completely empty board - it contains all possible sudokus!).
I like these .. and some are true not only for programming ..
Wumi is a sendmail milter, currently implementing 3 different tasks: blocking of specific filename extensions, tagging RBL matches (or refusing mail from listed hosts, and adding the "X-Kolab-scheduling-message" (or similar) on kolab kalendar mails. Wumi is configfile (stanza) configurable).
In Richard Stevens's book "Advanced Programming in the UNIX Environment" Chap. 19, running Programs from pseudo-terminals is explained, but the Example Program does not compile under AIX. I fixed it.
This is a very simple C Program, trying to reverse-lookup every IP in the given class C (ipv4 only) net. It prints addresses not having a reverse lookup, assuming you can use them.
Have a look into my photo galleries! Many of them are produced by a php script, which is able to show the original-size Pictures in a javasript (yyaggahh) Window. Several other features are included. You will also find the tool the generate the thumbnails there.
Since nobody I know can solve the witches puzzle without the help of a computer, I had to give C a try ;-) The original Version was written in Basic, but the C version is faster. I am sorry I dont know the name of the algorithm I use here, but maybe you can tell me! The solution comes within some miliseconds on contemporary hardware (speaking 2002).
This Program is in fact a Mastermind Player - the C version is very fast and allocates quite a lot of memory if you #define COLORS and #define PLACES suffiently high. Try and play!
