By running mprime, I was able to find out that my cpu fan was not working! The processor was getting hot and mprime was reporting errors; I then opened the case and found out that my CPU fan was dead.

1) just buy the CD : no box, no printed manuals, just a CD containing the software and the documentation in electronic form. or 2) buy the box with everything included in 1) plus a printed manual for a couple more $$$.
That way, people could have the best of both worlds. Pay less and use electronic media or pay the lumberjack to cut some trees.

Home-built device can cause air chaos
April 19 2000 at 11:35PM
Paris - The Global Positioning System (GPS), the space network that helps aircraft, ships and explorers to navigate, can be jammed using cheap equipment bought from stores and knowledge acquired on the Internet, New Scientist says.
A United States air force team, dubbed the Space Aggressor Squadron, was set up to look for weak spots in satellite communications and navigation systems, the British scientific weekly says in next Saturday's issue.
Playing the part of a potential enemy, two rookie engineers were able to build a satellite jammer by downloading information from the Internet and purchasing equipment from home improvement stores and electronics "swap meets".
For only $7 500 (about R49 500), they built a device using a UHF signal amplifier and noise generator, copper tubing which acted as an aerial, with desultory pieces of wood and plastic piping. A petrol-driven electricity generator provided the power.
Loaded into a pickup truck, the device was "an effective mobile jammer", capable of blocking satellite antennas or military UHF receivers, it says.
"Different components could be used to jam other frequencies, such as that of the Global Positioning System," it adds.
The GPS uses signals from several satellites in an orbiting constellation to triangulate a position, with accuracy down to a few metres.
It is becoming so prevalent that there are now GPS systems being incorporated in top-of-the-range cars, as well as GPS wristwatches.
John Pike, director of space policy at the Federation of American Scientists, told the magazine that it was "simple" to jam the GPS, because the satellite signal is weak.
But he believed that the latest generation of global communications satellites would be immune to similar home-built equipment, as they are "heroically resistant to jamming". - Sapa-AFP
Je suis consterné de voir la réclamation en dommages que votre compagnie a fait à l'association Leonardo.
Votre compagnie ne peut posséder le nom Leonardo pas plus que pape Jean-Paul II ne peut posséder le nom Jean-Paul! Ce que vous avez fait est une très mauvaise pratique et doit être puni. Votre compagnie mérite d'être mise en banqueroute pour avoir commis un acte si mauvais!
Je m'assurerai que tous ceux que je connais évitent de faire affaire avec votre compagnie.

It's a shame that the docs of the hardware don't cover this or at least give some insight into why those particular ports are open, etc.. I think users that actually spend hard earned money (or not so hard earned) to buy the product deserve to know.
What I don't understand is why does Sega taught that people wouldn't find out! Portscanning is really easy and can be done by a lot of people.
I don't know if you could get around it by calling MP3s DATA files, instead of music. Or what if you used a weak cypher? How about if you transmitted "All Country, All The Time", nobody in his right mind would call THAT music.
No, (at least in Canada) you cannot broadcast anything; by broadcasting, I mean always sending something to anyone. Also you cannot encrypt what you send in the air; the police had to ask for special permissions to do this. Even more, a couple of years ago (I don't know if it's still applicable) you could not talk in another language than the 2 officials in Canada (French & English), this was considered as 'encryption'...
If you Become a amateur radio operator (HAM), you'll be able to legally broadcast on most frequenties (HF, VHF, UHF). You'll even be able to try out radio tv, and satellite transmissions!
To become a HAM, you'll need to pass the FCC exam, then you'll get a license that will cost you about $30 a year. You can get more infos on Yahoo! or at this HAM-HOWTO site.

I'd rather have the option to
1) just buy the CD : no box, no printed manuals, just a CD containing the software and the documentation in electronic form.
or
2) buy the box with everything included in 1) plus a printed manual for a couple more $$$.
That way, people could have the best of both worlds. Pay less and use electronic media or pay the lumberjack to cut some trees.

Well, it looks like the should also sue yahoo.se since they also link to illegal MP3 sites.
Hum, that may be because Yahoo.se has lawyers to defend themselves, what a 17 years old boy doesn't.
