SAP DB is a code fork of ADABAS-D, a database developed by "Software AG" in Germany. Initially, Software AG was meant to develop the database and SAP would sell it together with R/[2|3]. But ADABAS aka. SAP DB was buggy and unsuitable for larger installations.
Soon, the Internet came and everybody at SAP started loving Java. But the JDBC driver of ADABAS was (and still is) a big mess. The developers at SAP had spent their time fixing Software AG's bugs. Now, they had a stable database but no connection to their new applications...
Incidentally, it was fashionable at that time to "give something away for free" if you were a big IT company so SAP decided to open-source SAP DB because it was no threat to their business and they had failed to replace Oracle etc. anyway.
SAP DB is a very good RDBMS and SAP is supporting it. But it just came too late to replace Oracle et.al. at SAP's customers and it came too late to compete against MySQL and Postgres on the "open source market".
However, since it's almost identical to earlier ADABAS-D versions, it's very popular among ADABAS users since Software AG changed their licensing policy for ADABAS-D;-)
Just compare http://www.linux4.tv and http://embedded.censoft.com/. Seems like the guys at Century Software are trying to get someone to program software for free so they can sell their set-top boxes later.
Besides, with digital TV/HDTV you really do want to get the original MPEG2 stream instead of decoding it once, and then encoded again when you record. Any set-top boxers/satellite recievers with firewire out?
I don't know about the availability of DVB (== Digital Video Broadcast, a standard developed and deployed in Europe for digital TV in MPEG-2 format) content in the U.S., but there are solutions available that do just that. Have a look at http://www.linuxtv.org or http://www.cadsoft.de/people/kls/vdr/
Computerized voting is bad. Make it simple!

Computerized voting is a bad idea. Yes, there is enough hardware and software available to create a voting system that is secure and reliable. These things have been tried and there have always been problems and glitches that falsified the result. Just search RISKS for computer and voting...
After all, the result will be the same anyway: Today, ballots are invalid because people punch the wrong hole. Tomorrow, my voting record will go down the drain when the database server crashes.
I probably don't know enough about your voting system in the US, but over here in Germany, people have to take a pencil and mark their candidate with a cross (1 line on paper = 1 candidate). The pencil will sometimes break, but that won't invalidate your vote and you can always etch your selection until you leave the voting booth;-)
I didn't notice any increase in speed of file accessing, but it
was fast at rebooting.
From my personal experience (haven't had a look at the internals of ReiserFS yet) ReiserFS is faster than ext2fs when accessing files and especially directories. We have a couple of servers running ReiserFS with large directories (~ 150,000 files per directory). It takes a couple of minutes to list such a directory with ext2 but only seconds on a ReiserFS partition.
Maybe I'm missing something here, but what is it about QMail that allows you to get around 16bit UIDs? Do you just use vpasswd and users/assign for everyone or is there some less, err, clunky way in which it helps?
Use LDAP for all email accounts. The qmail-ldap patches are available at http://www.nrg4u.com.
One thing to watch out for regardless which solution you use is that (last time I looked) linux (or is it ext2?) is limited to 16-bit uids. There's ways to get around that; I just wish we'd considered it when we started.
A good way to get around this is using qmail's LDAP patch. This way, you only need qmail's own local users. You should be able to convert your existing users to LDAP with no problem.

BTW, simliar projects have been around over here in Europe for quite a while - and those require no registration to download software and specs. Just have a look at http://dbox2.elxsi.de/ or http://www.cadsoft.de/people/kls/vdr/ ;-)
