If you need to test your RAM, Microsoft offer a free tool called windiag. The tool has its own loader, so it works autonomously for Intel or AMD processors, this means it works for Intel Macs or Linux Systems just as well as for Windows machines. You can download the ISO file here, burn a bootable CD and boot your computer from the CD. That's it.

Go here for the German windiag website.

And here's a reminder on how to burn an ISO disc image in Mac OS X:

1. Insert a blank disc.
2. Start Disk Utility.
3. From the File menu, choose Open Disk Image and select the ISO to be burned.
4. In the list of volumes, you will now see an item representing the ISO file. Select it.
5. Click the Burn button and follow the instructions.

Easy Crop is a lightweight drag&drop utility to crop images, supporting various image formats. Drag an image you want to resize/crop into Easy Crop, select the required size and drag the result into the application you want it in, e.g. Ecto or Mail. No steps like saving in between. Nice!
What I use it for most of all, is rotating portrait pictures, this never really seems to work from Preview and many other photo apps...

Especially as a companion for the blogging tool Ecto, Easy Crop comes in very handy. Regarding Ecto this function should be built in really. But it isn't. It is no freeware, but the price I think is OK at $15.00 for a family pack.

Mail Status Control is a nice little app for OS X, that indicates new mail with an icon in the menu bar. it also lets you set a keyboard shortcut to create a new mail message without having to switch to the mail app first. Cool!

Warning: banal content! Apple's remote control that comes with all new Macs was fun to fiddle with ONCE. Then it lay there getting ever more dusty. Working at my desk today i listened to iTunes on shuffle mode and often I'd move my cursor to the iTunes Dock icon, pause a little and select "next" to skip to a better song. It just seemed like too much effort, too much distraction from work. So I tried the remote, wondering if it works without the Front Row app running - and it does! And it reacts instantly. So the next track is now one push of the button away. Nice! Now PLEASE get back to work ;)
