I would like visitors to see advertising on my site with is relevent to my intended target audience. This could be done by allowing the publisher to add additional keyworks to the Adsence search. (eg. locality name)
Re:The shortcomings of SQL - Postgres

An Alternative to SQL?

· Score: 2, Interesting
Prior to PostgreSQL, the Postgres database was based on another query language other than SQL.
One of the main reasons why PostgreSQL took off after this was that it changed over to SQL in response to community/industry request and requirements (and openness to community contributions), bringing it in line with the industry standard.
I suspect that the next evolutionary step will be to allow multiple query languages to be used on the same DB engine.
It took me less than 2 minutes to: - plug the 3G PCMCIA card into my Fedora laptop - 'dialup' (it presented as a serial modem) - setup routing from the local LAN - setup masquading and firewalling - and let local users know that they could now
start browsing the internet!
This is an example where an open source solution may actually benefit everyone..

This would enable encryped DVDs to be distributed securely. What happens after they are decrypted and played.. well, thats up to how much they trust the people with the screener DVD's.
The technology will also only work when you know where the person/camera is whom you are trying to be tansparent too..
eg. The wall and floor examples are good because
it will look like a picture to the viewer.
The cloak example will not work as well unless you specify the direction of the viewer, or the background is resonable uniform (eg. Forrest)
It may be worse, as it could pickup moving object behind you (in a different direction) and cause the wearer to stand out due to the unexpected movement to the viewer!

Here are the scripts that I use to do just what was suggested. This doesn't work with dynamically linked libraries (whose directories still need to be added to/etc/ld.so.conf) and programs which do there own 'directory-thing'[TM] (eg. Sendmail, Apache, Samba). One thing I haven't figured out is the best way to handle configuration files. (In their own etc directory or in/etc?)

Do you think that we are becoming too dependent on computers in our science and engineering. For example, are there useful mathematical techniques being lost because we are relying more on symbolic mathematical packages (mathematica, matlab etc).
I've found that there are very few prospects for people with physics degrees. After 5 years of a Mathematical Physics Ph.D., which I did for the love of the subject, I've ended up working as a Linux Sysadmin because that's how I could make a living.
How can the study of physics be encouraged when this situation continues?

Where I work we are at the end of a project, and are just starting to make use of a program called 'doc++' (see freshmeat.net).
There must be other tools like it (I believe that the GNOME people have something similar that creates SGML docbook documents). It takes inline comments in c/c++ code, above each declaration, and produces a design document (HTML or latex). This could be useful in the design process if used from the beginning (as suggested above) with a change log, and everything stays together in the code.
