If your host system uses Time Stamp Counter and Virtual Machine guests use kvm-clock, then you should not use ntp on the guest. But what if you sync the physical host to a good Internet time source and just sync the virtualized guest to itself?

One of the best things you can do for any car is to give it better shoes. 500+ horsepower is useless if you can’t get that power to the ground. While in the tuning shop, you can buy tires and it will ask if you want to install them now. This is one way to change the tires, but many races require a specific type of tire. What if you want to change to another set of tires you already own?

An unlucky victim had her iphone erased by mistake. This was made possible because she had an application that allows her to sync with a Microsoft Exchange Server. Even though this was her own person phone, an Exchange admin was able to wipe out her data. Keep backups of your data, limit access controls, and be mindful anytime you install or update an application.

You’ve probably found an endless supply of URLs where people complain that they can’t get anything to boot with qemu-system-ppc and many supposed guides to follow that work. It’s almost impossible to find functional examples of how to run qemu-system-ppc without a kernel panic, core dump, or ending up in bios limbo. So here’s one way I came up with that works for me.

You’ve added a whole directory to get checked into subversion, and then realized you forgot to remove the binaries, or perhaps you had some hidden files, .nfs0001 or thumbs.db or something else you just don’t want to commit. There’s two ways to undo this situation.

I just logged into my gmail to find “buzz”, a new feature integrated into my gmail. I’m not quite sure what to think of it. Other than google, I don’t think anyone wants status updates in their gmail, but perhaps I’m wrong? I’d rather see Wave integrated, once it stops hiccuping of course.
