Perl object can be any blessed reference, they don't have to be hashes. You can use a scalar or array variable too. It's just that blessing a hash gives you the added benefit of using the hash keys like instance variables.
Still, on most Linux distros you're talking about maybe a dozen keys that the user themselves specifically trusted, and the chances of any 2 Linux users trusting the same 3rd party will be remarkably small. Under the Windows model, any Verisign trusted certificate will get you access, there's got to be millions of those (unless they restrict drivers to a different root certificate than app or website signing, but even then it'll be in the thousands), and if any one is compromised then every Windows user would be vulnerable.
It's not impossible, it just always results in this: http://xkcd.com/716/
There are always exceptions made to the Feature Freeze, and since this is a major initiative for 10.10, I have no doubt they'll be able to keep updating it until the RC.
Yes, just image the horror of organisms that convert water into it's base parts, and are capable of growing, reproducing and spreading.much
It's unfortunate that you had to go with the old "screw the techie" prediction, because the first part of your post was quite right and doesn't deserve to be grouped under the -1 Troll mod. Given Shuttleworth's own statements and actions, here's what I see the business plan being:
0) It's nearly impossible to compete with Microsoft on non-OS products, because of their monopoly status.
1) Take a product that has the potential to make an OS a commodity, nullifying Microsoft's major competitive advantage in ever other market.
2) Turn that product into an actual competitor by matching or exceeding Windows in quality and features
3) Get people using the product, and more importantly get vendors selling it
4) Produce products that compete in a different market, and take advantage of having a free, commodity OS
5) Profit on those other products now that MS can't use their Windows marketshare as the sole competitive advantage
Ya, Dell and some others offer preinstalled..but that isn't Canonical offering it. It needs to be *their* machines with their software that they know will work.
Canonical certified all the Dell desktops, laptops and netbooks that ship with Ubuntu pre-installed, they even provide Dell a custom install image of Ubuntu that is designed to work with those particular hardware setups.
Dell is also offering a line of server products that use Ubuntu Enterprise Cloud: http://www.thevarguy.com/2010/03/24/dell-backs-ubuntu-enterprise-cloud/
Vorbis and Theora as both tributes to characters in Terry Pratchett novels.
The moon has about 100x the concentration of Helium3 on earth. Since He3 holds the promise of truly clean fusion power (no radioactive byproducts), it seems pretty likely to be of high value in the next 50 to 100 years.
If you require someone to chmod +x an installer before running it, the user will chmod +x a trojan just as easily as the installer for an app not in the distribution's repository.
True, but they won't chmod +x FunnyPicture.jpg.exe just to view a picture.
By the time a Windows OS hits its end of life, the hardware is usually in need of replacing anyway due to new applications' higher hardware requirements [wikipedia.org].
Minimum Requirements for Ubuntu 6.06:
256MB RAM
3GB HDD
Minimum Requirements for Ubuntu 9.10:
256MB RAM
4GB HDD
But how is it useful for end users without the service? Patches that change semantics of a struct in the kernel need manual intervention.
This is something that can be provided by mainline kernel devs or your distro's kernel maintainers. KSplice isn't the only one that can do it.
True, a downloaded malicious program needs to be chmod +x, just like the installer for any other program that sits outside the package system. But what exactly were you talking about?
The comparison I was making was to downloaded
The only time you need to pay for a Windows OS upgrade is either A. for a new machine or B. for the equivalent to an upgrade from one Ubuntu LTS to the next LTS.
A regular release upgrade in Ubuntu is not equivalent to a ServicePack in Windows. Nor is an LTS release upgrade necessarily equivalent to a regular release upgrade in Windows. But either way, Ubuntu releases will continue to be free, where as you'll eventually run out of SP upgrades on your version of Windows.
Ksplice costs 48 USD per year [ksplice.com] unless you're on Ubuntu, and it isn't available for SuSE or Fedora at all.
KSplice Uptrack is a service that costs money. KSplice itself is open source, and available for free.
