Using Microsoft Natural Ergonomic 4000 Keyboard with Mac OS X El Capitan (10.11)

Microsoft Natural Ergonomic 4000 Keyboard is great to your wrist and hands for people who uses keyboards a lot. It’s a quite affordable keyboard as well (~$50).

Microsoft provides Intellitype Pro 8.2 software/driver for Mac OS but the official support ends with Mac OS X 10.7 (Lion). The software works to some extent however with OS X 10.10 Yosemite, for example, you can still swap Windows Key and Alt/Option key to match the layout of a Mac keyboard, which is probably the only reason I’d need the Microsoft driver.

With the upgrade to El Capitan, Intellitype cannot even detect the keyboard any more, so it becomes completely useless.

But there is a saviour, Karabiner, “A powerful and stable keyboard customizer for OS X.”. Karabiner utilizes Mac OS X accessibility API and enables you to do whatever you want with keyboard mapping plus many other things.

The wonderful thing to me is that Karabiner even has an option for Ergonomic 4000 keyboard! All I wanted can be archived by selecting a couple of options:

Don’t Be Fooled! AWS and Openstack Show Different Fingerprints of Imported Public Key

Don’t be fooled! AWS and Openstack are fingerprinting an imported keypair differently.

AWS uses the equivalent of:

openssl rsa -in id_rsa -pubout -outform DER | openssl md5 -c

while Openstack uses ssh-keygen:

ssh-keygen -q -l -f id_rsa

They could end up showing different values for the fingerprint of exactly the same public key.

Automatically starting Cygwin/X Window Server without xterm.

From True Blade:

To start the cygwin X server, create a new shortcut in your Startup group. It should execute this command:

<path-to-cygwin>\bin\run.exe -p /usr/X11R6/bin XWin -multiwindow -clipboard -silent-dup-error

For my setup, where I have cygwin installed in c:\opt\cygwin, the entire command is:

C:\opt\cygwin\bin\run.exe -p /usr/X11R6/bin XWin -multiwindow -clipboard -silent-dup-error

Now, whenever I log in to Windows, the X server automatically starts, and I don’t have any annoying text windows that I might accidentally close.
