Keeping your PC pure and fast with virtualisation

A couple of weeks ago Josh posted about virtualising your overloaded, slow, not-rebuilt-for-years PC, and keeping it on standby within a new build in case you need anything on it.

How about the idea of keeping that new build clean — putting on only your most frequently used, essential applications, with everything else going onto a virtual PC?

For me, that would mean Office, Firefox, my usual web-building stuff (Photopaint, UltraEdit, Filezilla), Nero, and one or two others, such as perhaps Trillian. I’d draw a line under them, and anything else not worthy of a permanent spot in my Windows setup would be virtualised, possibly in various separate virtual PCs, setup for different roles: one for Visual Studio, one for trying out freebie apps from mags, a Linux setup for LAMP development, one for stupid software that insists on running as Administrator, etc, etc.

Windows 98 under Virtual PCWhat to use for the virtual machines? There’s a few different options.

The freebie Virtual Server will only support Windows NT 4 and above, and only server OS’s, which to my mind would unnecessarily weigh down your virtual machines with more than they need. (Linux as a guest OS seems to be coming.)

Another option is the free VMWare Server, which will host a wider range of guest OSs.

The non-free Virtual PC will host just about any x86 operating system. If you don’t want to try the 45 day free trial, it’ll set you back A$215 or so, or it’s available via MSDN Universal.

A problem would be performance, of course. It’s not like emulating a 2Mhz 6502 under BeebEm. But then, hopefully it’s not as bad as what I’ve seen on my brother-in-law’s PowerPC Mac trying to run x86 AutoCad in Windows 2000.

Nonetheless games and other performance-intensive apps may not perform well under virtualisation, especially if they require particular hardware. And yet they would benefit the most, as they often have installers that wreak havoc on Windows setups, chucking weird-arse DLLs everywhere. As the “Virtual PC Guy” is fond of telling us, a lot of the older games run okay, but newer ones might be a problem.

Maybe the only solution there is to put them on a completely separate computer, or move up to Intel’s latest chips which have better support for virtualisation.

Or give the whole thing up and resign yourself to a slow computer with rebuilds every year or two.

I think I’ll try Win98 with a couple of recent-ish games (say, Midtown Madness 1 and 2) and see how it goes.

Fun with wildcards and DOS 8.3 filenames

I’ve found under some circumstances, new versions of Windows (XP and 2000, using NTFS) are still looking at the DOS 8.3 versions of filenames when using wildcards.

Real world example: a set of files such as tpo12345.xml tpo12346.xml tpo12347.xml etc. To find these, you’d use a wildcard such as tpo?????.xml

If you have a file called tpo1234567890.xml, it shouldn’t match using this wildcard, but it does, because the filename’s backward-compatible short version (in DOS 8.3 format) is something like TPO123~1.XML, which matches. It appears to only happen when the first part of the wildcard (without the suffix) is 8 characters long.

So it may be ten years since most of us said goodbye to short filenames, but it seems they’re still with us. I wonder if Windows Vista will still use them?

Windows Automatic Updates

The following question is clear, with the answers easily and quickly selectable.
Ask me once, fine. Ask me every fricken ten mintues, I kill you! I kill you!
But if you pick “Restart Later”, it obviously means “Ask me in another ten minutes”. Which is tiresome over an eight hour day.

I now understand how toddlers get all that candy they eat.

The quest for up-to-date drivers

I use Microsoft products every day, and indeed make my living off them. Doesn’t stop me slagging-off Bill Gates regularly of course, though Danny Katz would like us to leave him alone.

One of my pet hates has been the dumping of support for legacy hardware. It’s not just a Microsoft issue of course; the vendors are equally to blame (often even more-so). My own experience was that an old Diamond Viper V550 graphics card I have in one of my machines would do astounding 3D things when DirectX 7 was the latest version, but somewhere between 7 and 9, the 3D stuff went out the window. (Knoppix Linux didn’t like it, either.)

I’d long given-up on this particular issue, hoping to find the time at some stage to get super-brave and attempt to downgrade DirectX, which is theoretically possible, but certainly not for the faint-hearted.

Then the other day on a whim I decided to go searching for updated drivers for the card. Turns out NVidia (who bought Diamond) have put some new ones out. Well, newish. Okay, three years ago. Did I not find this the last time I looked, or was it really longer ago that I last tried?

Downloaded, installed. They work. Now my kids can play Midtown Madness 2 with fast graphics again.

I’m even pondering upgrading that ol’ Win2K to XP, now that you can get an Academic XP Pro for under $100. 512Mb RAM and a 1.something Ghz processor, so hopefully it should be able to hack it. Would avoid the kids arguing over who gets to use Windows MovieMaker. Must check the driver situation out first, though. That old dodgy TV capture card will be the tricky one…

Soft Taskbar Shuffle

Want to organise the order of your programs on the Windows XP taskbar? Then try the fantastic free Taskbar shuffle and shuffle to your hearts content. I always like to have Outlook the left most program, followed by Firefox. How about you? What order do you like your programs in? Or is just me?

Dev SSL certificates

If you’re just mucking about with IIS, you don’t really want to pay a CA to get a legit certificate, do you?

No, of course you don’t. Fortunately these guys have a freebie certificate generator. Mucho handy.

Just don’t even think about using it in production code.

Oh, and don’t get the page to email you the certificate to a mailbox you can only look at via Outlook. Outlook’s dumbarse “protecting you from shadows” attachment filter won’t let you at the CER certificate file that comes through.

No more security through obscurity

Feel safe using Firefox and/or Mac OS X? Don’t. This article discusses recent research showing both are subject to a number of vulnerabilities. Not as many as poor ol’ Windows users using IE, but still enough that it’s wise to be wary.

Not to mention the issues in the various media players.
