Setting up the danish public digital signature with Mail.app is not obvious, but this is what I did to make it work (needed it for setting up ePosthuset with my gmail account):
First install the Digital Signatur from DanID. You should end up with a .pkcs12 certificate file, probably located in ~/.oces Install the the certificate in your keychain. This is normally done by just double-clicking the .pkcs12 file. This should also open the Keychain Access application (Hovednøglering if you’re on a danish system). Locate your certificate—it will probably have your name, eg. Tobias Haagen Michaelsen for me.

Right-click the certificate and select “New Identity Preference…” (da: “Ny id-indstilling…”) and enter your e-mail address. Now comes the tricky part: As I have set up the account in Mail.app with my name and e-mail address, it doesn’t immediately recognize the identity because it has the e-mail address as the name as well, so you have to double-click the identity and change the name to match your Mail.app account.

And after restarting Mail.app it now Works on My Machine™
I wanted to use an external USB disk with a physical partition for a virtual machine in VirtualBox on my MacBook Air, and this isn’t obvious from the gui. So this is what I found out I had to do.
First, make sure that there is no partition on the disk. Then run this command:
VBoxManage internalcommands createrawvmdk -filename \
~/Library/VirtualBox/usbdisk.vmk -rawdisk /dev/disk1 -register
You can now create a virtual machine and use usbdisk.vmk to install a new OS on.
Update: Later, OS X might auto mount the volume created during install. You must unmount this before you can start the virtual machine again.

Finally got my connection running at nearly full speed. Mmmmm — speeeed.

For once I seem to be ahead on my feed reading

Cannot uninstall because a file could not be installed (and, the uninstall did not continue but was aborted)
