    Go to a nearest shop and try to life the 9" eee and the 10" eee. It's a difference. I have a 1.45kg tablet and when it comes to its weight it's really only borderline usable. The 9" eee on the other hand has the perfect weight - light enough, yet not so light to be shaking when you're reading an e-book on bus.

  8. Re:As per "Flamebait Story" on Ubuntu's Laptop Killing Bug Fixed · · Score: 2, Insightful

    You're writing "Wrong", but what you say isn't really in conflict with what I wrote. Yes, it's easier for a given developer to fix a bug in Linux software or in kernel/driver. Yes it's easier for them to achieve the perfect state where everything works according to specification/protocol. But when the ethernet card decides for no particular reason to send 1101 instead of 1100 every once in a couple of kBs, it's going to be a bigger deal in a cleanly designed system than in a self-repairing pile of junk.

    Given that these kind of bugs will be corrected only when the manufacturers will sell more than say 25% of it's hardware to Linux clients, I humbly predict that these bugs will be fixe in approximately infinity years.

  9. Re:As per "Flamebait Story" on Ubuntu's Laptop Killing Bug Fixed · · Score: 1

    Hardware will always have bugs and they always will be hard to fix. It's the OSes that should step up and act more like error correcting codes. Windows already kinda work like that - by being a monstrous pile of ugly hacks, it naturally gained resistance from relying on something external actually working.

    Yeah, I'm sure that the GNU stuff around the kernel (like bash and Gnome) has really big influence on the settings energy saving levels of hardware.

    "The problem can be considered notable in cultural trivia, as the only well-known paper ever published by Microsoft Chairman and billionaire Bill Gates (as William Gates), entitled "Bounds for Sorting by Prefix Reversal", describes an efficient algorithm for pancake sorting. In addition, the only paper published by Futurama co-creator David X. Cohen (as David S. Cohen) concerned the burnt pancake problem.

  19. Re:CSS = ACID? on Internet Explorer 7 RC1 Released · · Score: 4, Informative

    I'm quite sure it won't pass ACID2, but that doesn't matter - CSS support is still pretty good in MSIE 7 RC 1 and that's more that I hoped for. I just had to port quite complex CSS layout for MSIE 7 (used position:fixed hacks in MSIE 6, maxwidth emulation and whatnot) and all it took was to change one conditional comment (to ensure that these many MSIE-6-workarounds won't be applied to MSIE 7). Now I'm using exactly the same stylesheet for Mozilla, Opera and MSIE 7.

    Underscore hacks won't do the trick for MSIE 7 (which is probably good thing), pages with xml declaration are rendered in standards mode (which will cause some minor trouble, mainly because of that boxmodel change).
