Go Microsoft:

You know that Which Operating System Are You quiz?

Well, they’re gonna have to expand it to include all six versions of Windows Vista, whenever that decides to be unleashed unto the world. Hello, six versions? With the starter edition only being able to use 256MB of RAM and run three applications at once? Even eWeek says that “you would be better off running Windows 98”. You know what, instead of choosing between Vista Starter, Vista Home Basic, Vista Home Premium, Vista Business, Vista Enterprise or Vista Ultimate, how about I just run Mac OS X or Linux instead, you stupid tossers?

Jesus, the excellent lads over at Microsoft Research (who produce some truly world-class work) must be just cringing when they hear their big brother company do totally insane stuff like this.

OK, this is both ridiculous and cool at the same time. I need to write code for Mac OS X, Windows and Linux for work, and I like to work offline at cafes since I actually tend to get more work done when I’m not on the Internet (totally amazing, I know). This presents two problems:

1. I need a laptop that will run Windows, Mac OS X and Linux.
2. I need to work offline when we use Subversion for our revision control system at work.

Solving problem #1 turns out to be quite easy: get a MacBook (Pro), and run Mac OS X on it. Our server runs fine on Darwin (Mac OS X’s UNIX layer), and I can always run Windows and Linux with Parallels Desktop if I need to.

For serious Windows coding and testing, though, I actually need to boot into real Windows from time to time (since the program I work on, cineSync, requires decent video card support, which Parallels doesn’t virtualise very well yet). Again, no problem: use Apple’s Boot Camp to boot into Windows XP. Ah, but our server requires a UNIX environment and won’t run under Windows! Again, no problem: just install coLinux, a not very well known but truly awesome port of the Linux kernel that runs as a process on Windows at blazing speeds (with full networking support!).

Problem #2 — working offline with Subversion — is also easily solved. Download and install svk, and bingo, you have a fully distributed Subversion repository. Hack offline, commit your changes offline, and push them back to the master repository when you’re back online. Done.

Where it starts to get stupid is when I want to:

• check in changes locally to the SVK repository on my laptop when I’m on Mac OS X…
• and use those changes from the Mac partition’s SVK repository while I’m booted in Windows.

Stumped, eh? Not quite! Simply:

• purchase one copy of MacDrive 6, which lets you read Mac OS X’s HFS+ partitions from Windows XP,
• install SVK for Windows, and
• set the %SVKROOT% environment variable in Windows to point to my home directory on the Mac partition.

Boom! I get full access to my local SVK repository from Windows, can commit back to it, and push those changes back to our main Subversion server whenever I get my lazy cafe-loving arse back online. So now, I can code up and commit changes for both Windows and the Mac while accessing a local test server when I’m totally offline. Beautiful!

But, the thing is… I’m using svk — a distributed front-end to a non-distributed revision control system — on a MacBook Pro running Windows XP — a machine intended to run Mac OS X — while Windows is merrily accessing my Mac HFS+ partition, and oh yeah, I need to run our server in Linux, which is actually coLinux running in Windows… which is, again, running on Mac. If I said this a year ago, people would have given me a crazy look. (Then again, I suppose I’m saying it today and people still give me crazy looks.) Somehow, somewhere, I think this is somewhat toward the evil end of the scale.

I suspect that if you don’t know that Apple released their Boot Camp tool to enable normal PC operating systems to be installed on their shiny new ICBMs, you’re probably not a geek, and this article doesn’t really concern you…

Since there have been plenty of other articles written about Boot Camp and its implications for the future of the Macintosh, I won’t say any more about it here. I just wanted to say the following:

• Tuesday, April 4: Pick up shiny new MacBook Pro from my local AppleCentre.
• Wednesday, April 5, ~8pm Australian CST: Apple announces Boot Camp.
• Thursday, April 5, ~2am Australian CST: Windows XP SP2 installs on my Mac.
• Thursday, April 5, ~3am Australian CST: Visual C++ Express 2005 and Counter-Strike are installed (the latter running at a rather nice 72.7fps in Valve’s Video Stress Test).
• Thursday, April 5, sometime later: Parallels announces a beta of their Workstation product, enabling Macs to virtualise running guest operating systems. Hooray for x86 hardware virtualisation technology.

Not bad for the first three days of owning a MacBook Pro, really. Bring on the tech!

Well, some kind-hearted soul has finally written a kernel-mode Installable File System (IFS) ext2 driver for Windows NT/2000/XP. While it ain’t no reiserfs driver for Mac OS X (now that’d be worth some serious restecp), it’s still rather schmick. Plus, now that free kernel-mode ext2 drivers are available for all the major desktop operating systems, hopefully we’re one step closer to destroying FAT as the lowest common denominator filesystem once and for all…

We needed to set up some Annodex servers for demos this week, and our server software currently runs best on Linux. So, what to do if you’re using Windows machines which you can’t install Linux on for whatever reason, political or technical? Run Linux inside Windows, of course, via coLinux.

coLinux is great. No, scratch that — coLinux is really great. Not only does it work, it works really well: it’s fast (I really don’t think I’ve ever seen a Debian system boot up in 2-3 seconds), it’s stable, and it even uses a pretty small amount of memory, since Linux servers tend to be on the trim side. A full-blown Linux installation for us with Apache serving multi-megabyte multimedia streams to multiple Windows clients was using up less than 30MB of Windows’s memory pool. Low fat.

If you must have Windows on your desktop/laptop for whatever reason, but need Linux and are getting sick of doing the reboot dance just to switch OSs, give coLinux a whirl. And, if you want to get geek cred points, watch your friends’ jaws drop when they see X11 applications hosted on coLinux displaying in Cygwin/X; it’s pretty scary just how well it all works. Now, whither my coLinux for Mac OS X port (and flying car)?
