I am currently writing a control and monitoring software system that makes use of GPIO pins. Since I was at the CCC congress in Berlin I did only have my laptop and no real GPIO hardware...

With only a laptop it's a bit hard to write GPIO software, since laptops usually don't have any GPIO pins. So what I needed to test my new software was either a real device (out of reach) or... writing a simulator.

All of these projects, except dynload and mod_clamscan, are in the OpenBSD ports and packages collection.

• smtp-vilter, a fast and flexible content filter for sendmail
• smtp-benchmark, an SMTP benchmark programs
• ldapvacation, an LDAP version of the vacation program

Internet applications written in the Java programming language are mostly designed as applets that run in a Java enabled browser like Netscape.

There are, however, still many web-browser around that don't support Java. These need to use CGI (Common Gateway Interface) to access interactive pages on the web. Although CGI programs traditionally were realized using a scripting language like Perl or even the Bourne shell, nothing speaks against using Java to write CGI program.
