    At this point C could now have a new value after the C++ operation. This is not defined by the standard AFAIK. The correct way is not to write it at all, because why the hell would you need that in sane code.

    Whether or not all of the claims in Guttman's article are true (and I agree that a few are obviously based on miscommunication in Microsoft's own documentation), it is clearly evident that Vista is a lot more heavyweight than XP without really offering anything. Now either a large chunk of that is DRM, or a small chunk is DRM and the rest is sheer unmitigated engineering failure. Either way it's bad. Whatever they're doing to fix Windows 7 is very welcomed and it looks like they've learned their lesson, but we can't claim Vista doesn't suck just because some of the reasons it sucks aren't completely valid, because there are plenty of other reasons it does still suck.

    Unlike Windows, if you install a very lean Linux distribution, even one with up-to-date package versions, it will be absurdly fast as you'd expect from modern hardware. Just because Ubuntu is being burdened doesn't mean the FOSS landscape itself is.

    The algorithms and data structures in almost all open source applications have either stayed the same over the years, or gotten better, with the notable exception of some programs like GCC which have used the increase in system resources to advance compiled code optimisation rather than compile-time performance.

    This whole "of course newer is slower" thing is just Microsoft brain damage. Apple is another company which regularly improves performance and scalability in its software products, even with DRM problems similar to Vista.

    Did you know that by now hundreds/thousands of Windows *system* *calls* have built-in backwards compatibility checks to support programs whose source code is not available for maintenance? You're paying a performance penalty every time you make a system call, with no option to turn it off, just because someone somewhere might want to play The Sims. Open source solves this problem by fixing the program, rather than hacking every layer of the OS to support old bugs. You can't spell "backwards compatibility" without "backward".

    I am very confused as to why this should apply to something like e.g. a C compiler. Why would anything but a media decoder/player/encoder require media DRM? Last I checked C compilers don't require kernel DRM support to detect copyright violations in source code. Although looking at how big and slow Visual Studio has gotten over time, I wouldn't be surprised.

    If Microsoft had been even remotely competent they would have included at least two checksums for each file, so that once you downloaded them from an untrusted source, the file becomes trusted by verifying all of its checksums. Just one checksum may be cracked but two in different algorithms are much less likely.

    Nope - thanks for the update. SSD will only defeat software file shredders if run through an FTL (which most are, but we should be moving away from this). However if your flash-optimised file system like ubifs does rotating writes then once again a file shredder is useless and will just waste erase blocks.

    Ideally you'd just use block level encryption before writing the data in the first place. For years now it has been very easy to set up a volume manager (lvm, gvinum, ...) over an encrypted volume (device-mapper, geli) over software raid (md, gmirror) on server-class operating systems like Linux and FreeBSD. You get volume management, RAID and encryption, at the cost of entering a password and some ever-shrinking performance penalty.

    I know you're trolling and probably high as a kite being flown by another kite, but just in case anyone takes you seriously, let it be known that file shredding is not a kernel's job, and using a non-journalled filesystem (or a journalled filesystem set to not journal data blocks) will allow file shredders to work just fine.

    What poor algorithm? Hash collisions aside, a password is a password.

    So, Mr Formal Education In Operating Systems, will OpenBSD refuse a valid username and password combination because the person logging in has a hidden evil deep in their hearts, unlike Windows which has blind faith in all valid passwords?

    You're very confused. It's true that, if configured to accept username and password authentication, any system will treat a valid username and password as sufficient. That's why most professional administrators use public key authentication with good private key protection policies. But given an equal configuration of username and password, OpenBSD will be just as trusting as Windows.
