Comment Think Bigger (Score 2, Interesting) 365

How about a few thousand solar satellites in orbit around the sun, transmitting energy directly to power stations on earth where the energy gets redistributed?

How about no more batteries?

Driving cars that get their energy straight from the sun?

Cellphones that do not just get their energy through an entangled pair, but also their 'net connection?

Or why not just dump one of those entangled particles into the sun? Or, if we're feeling particularly paranoid, into a neighboring star?

No. It has to do with the impedance of the cables. Since there is a lot of empty space around the powerlines in the air, there is very little loss from the electromagnetic field that is generated around the conductors by the power flowing through it. If you bury the cables, there is a lot more electrically conductive material near the power lines creating more loss of power. In effect, the power cables would lose a lot of power heating the ground around it. At least, if I remember my classes correctly.

If you're cooking YOU'RE IN THE DAMNED KITCHEN! Why in hell would you want to access your kitchen appliances from a telephone or a videogame?

So you can cook WITHOUT being in the damned kitchen? I would love to have a gkrell like app monitoring the temperature and humidity in my pots, maybe include some video.

It would have saved me a shitload of broken nails trying to get the burned black bits out of my cooking pots...

Comment Atom 330 Desktop/Server (Score 3, Informative) 697

I am running a system based on an Atom 330 motherboard from Intel. It has 2GB of memory and a 320GB harddisk. I payed about 300 euros for the complete system, but you can probably get it cheaper. The motherboard with cpu was 70 euro.

I like it because it is powerful enough to do most of my daily computing. It runs an apache, a mailserver and serves as my desktop machine. I use a 1680x1050 Gnome desktop, fullscreen video, browser and email client. It has, in practise, completely replaced my normal (1300 euro) desktop. After I replaced the crappy fan that came with the motherboard it is now perfectly silent.

The whole system, under load, uses 28Watt.

Comment Re:ebay maybe? (Score 1) 546

If you make an image of your platter with an electron microscope you can measure the actual magnetisation of the bit (which is an analog value) on the harddrive and have a good idea of what previous values were. Add to that the error correction mechanisms on every harddrive and you have a good chance to find the data on it before you put all zeroes over it.

Comment Weird metric (Score 1) 187

I have no idea of the real code behind those file systems but I find "external calls" a bit of an weird metric. The more "common code" used by the file systems, the more "external calls" would be seen, while this would actually be a Good Thing.

Comment Re:Second on the drive thing (Score 1) 835

I think it would require listening to changes on every directory on the filesystem with an active daemon. You could keep the database up-to-date like that, but I can assure you lots of overhead when doing file manipulations. (compiling, unzipping...).

I'm unsure what you mean with breaking something of POSIX, but it would mostly likely ruin your "computing experience".

Submission + - Say NO to the M$ OpenXML format as an ISO standard (noooxml.org)

magesor writes: "Say NO to the Microsoft Office format as an ISO standard

There is a petition that I just copy here:

I ask the national members of ISO to vote "NO" to the ballot on the Microsoft Office OpenXML (OOXML) specification to become an ISO standard for the following reasons:
  1. There is already a standard ISO26300 named Open Document Format (ODF): a dual standard adds cost to industry, government and citizens;
  2. There is no provable implementation of the OOXML specification: Microsoft Office 2007 produces a special version of OOXML, not a file format which complies with the OOXML specification;
  3. There is missing information from the specification document, for example how to do a autoSpaceLikeWord95 or useWord97LineBreakRules;
  4. More the 10% of the examples mentioned in the standard do not validate XML conformity;
  5. There is no garantee that anybody can write a software that fully implements the OOXML specification without being liable to patent damages or patent license fees;
  6. This standard conflicts with other ISO standards, such as ISO 8601 (Representation of dates and times), ISO 639 (Codes for the Representation of Names and Languages) or ISO/IEC 10118-3 (cryptographic hash);
  7. There is a bug in the spreadsheet file format which forbids to enter any date before the year 1900: such bugs affects the OOXML specification as well as software versions such as Microsoft Excel 2000, XP, 2003 or 2007.
  8. This standard has not been created by bringing together the experience and expertise of all interested parties (such as the producers, sellers, buyers, users and regulators), but by Microsoft alone.

For those with long-term partners it also lets you see if your partner is ready for marriage before you pop the ever-so-dangerous question.
Just hope that the love of your life hasn't lied to the website in order to humilaite you."

Feed AACS hacked to expose Volume ID: WinDVD patch irrelevant (engadget.com)

Filed under: Home Entertainment

var digg_url = 'http://digg.com/movies/AACS_hacked_again_to_expos e_Volume_ID_WinDVD_patch_irrelevant'; The DRM "protecting" HD DVD and Blu-ray Disc films -- AACS -- continues to unravel at the seams. In parallel efforts, hackers in both the Xboxhacker and Doom9 forums have exposed the "Volume ID" for discs played on XBOX 360 HD DVD drives. Any inserted disc will play without first authenticating with AACS, even those with Volume IDs which have already been revoked by the AACS LA due to previous hacking efforts. Add the exposed processing keys and you can decrypt and backup your discs for playback on any device of your choosing. So yeah, it looks like last week's WinDVD update has been quickly and definitively made useless just as we expected it would be. Well, for XBOX 360 HD DVD drive owners anyway but you can see where this is heading, right? Now go ahead AACS LA, revoke the Toshiba-built XBOX 360 HD DVD player... we double-dog dare ya.

Submission + - Vista may reach an astonishing 12% of market

RockDoctor writes: Harris Interactive, a polling company, have been conducting a survey of users, asking their likelihood of "switching or upgrading" to Vista : 67% no, 20% not sure, 12% yes. The corresponding numbers for before the Vista release were 31%, 49% and 20%. Which you could read as 40% of Vista's potential customers have been turned away by the reality compared to the hype, and many "maybe" people saying "no". The survey is reported at Information Week, and the details are at Harris Interactive.

"A lack of consumer faith in Microsoft's promises that Windows Vista will significantly improve their computing experience is what's behind the low numbers, said Milton Ellis, VP of Harris' Technology Group."

Ahh, poor little Bill, people not believing his Marketing Department. Poor Billy!
