I've done the exact same thing. After using Unity for a couple of days and hating it I've installed Gnome 3. I've expected it to be great, it was a great disappointment. Thought about installing Mint but decided to give Debian a try instead. After several hours of tweaking to make it just right (mostly upgrading to wheezy (testing), font tweaks and theme) I'm in love. I don't think I'll ever use anything else.

I remember having a lot of fun playing Frontier on my Amiga. It's the only game I've played that has a realistic space flying physics. For example, if you come out of the hyperspace at some 1000km/s , the fastest way to slow down is to turn around and fire the main engines. I also loved manually landing on space stations. First you get to the star system, navigate to the planet, get to the space station (monitoring the relative speed to the station so you don't slam into it) then find the docking bay, sync your rotation to the stations and slowly float in.

Human eye is actually able to detect single photons but we're programmed not to notice them unless they are above a certain threshold.

Quote from: http://math.ucr.edu/home/baez/physics/Quantum/see_a_photon.html

The human eye is very sensitive but can we see a single photon? The answer is that the sensors in the retina can respond to a single photon. However, neural filters only allow a signal to pass to the brain to trigger a conscious response when at least about five to nine arrive within less than 100 ms. If we could consciously see single photons we would experience too much visual "noise" in very low light, so this filter is a necessary adaptation, not a weakness.

Security

+ - Securing a PC when others have physical access?

An anonymous reader writes "I will be going to college next year and I am concerned about room-mates and other random people having physical access to my computer and viewing/copying my data or putting remote access trojans on it while I am away. I am running Windows XP for software development purposes (and lets be honest, games :-)) and I know that running Windows is a problem but at this point I don't think it can be avoided. I will of course have anti-virus and firewall software but what is the next step? Thank you for reading!"
Supercomputing

judgecorp writes "D-Wave Systems of British Columbia is all set to demonstrate a quantum computer. Simple devices have been built in the lab before, and this is still a prototype, but it is a commercial project which aims to get quantum devices into computer rooms, solving tricky problems — and cracking all our codes. Most quantum computers have to be isolated from the outside world (look at them and they stop working). This one is an "adiabatic" quantum computer — which means (in theory, says D-Wave) it can live with thermal noise and give results without having to be isolated. There's a description of it here — and pretty pictures too."

For the 37000th time. I never said a word about emulating any PostgreSQL features in PHP. The emulation comment was completely MySQL-related to get around a limitation that when you use prepared statements MySQL doesn't use the query cache. If you application can benefit from the query cache, then PHP has an option to emulate prepare/execute in PDO. You are reading a half-baked second-hand account of a talk I gave.
