Edit:
After writing this, DSA got deprecated then later removed. See [WayBack] Secure Secure Shell.
When working with SSH private/public keys (often because of ssh-keygen), and using DSA for auhtentication, these are the relevant files:
- $HOME/.ssh/id_dsa:
(on the local system)
The $HOME/.ssh/id_dsa file contains the protocol version 2 DSA authentication identity of the user.
- $HOME/.ssh/id_dsa.pub:
(on the local system)
The $HOME/.ssh/id_dsa.pub file contains the DSA public key for authentication when you are using the SSH protocol version 2. A user should copy its contents in the $HOME/.ssh/authorized_keys file of the remote system where a user wants to log in using DSA authentication.
- $HOME/.ssh/authorized_keys:
(on the remote system)
The $HOME/.ssh/authorized_keys file contains authorized DSA public keys (each line is the contents of a $HOME/.ssh/id_dsa.pub file) of users on systems that are auhorized to login on the remote system.
Important:
Be sure to transfer the contents of the local $HOME/.ssh/id_dsa.pub file to the remote system in a secure way.

Finder on your Mac by default does not show hidden files, and the console has vi, which lots of people find awkward to use.
There is an easy trick to open a hidden file like ~/.bash_profile (for instance to add an alias) with a visual text editor.
Just execute this in your terminal:
- Always with TextEdit
open -e ~/.bash_profile
- For the default text editor (usually TextEdit)
open -t ~/.bash_profile
- For a specific text editor (in this cast TextWrangler)
open -b com.barebones.textwrangler ~/.bash_profile
The man open(1) page has more information on the parameters you can pass to open.

This 5 year article from 2007 (which was an update for the 2002 version) is still very up to date in 2012: Top Ten Mac OS X Tips for Unix Geeks – O’Reilly Media.
Originally it was to promote Mac OS X for Unix Geeks – O’Reilly Media. In between the updates there was Mac OS X Panther for Unix Geeks, 2nd Edition – O’Reilly Media.
Now it is to promote Mac OS X for Unix Geeks (Leopard), 4th Edition – O’Reilly Media.
Note there is also a nice, but independent presentation with the same title from HTGR-MacOSX.

It starts to be not so funny any more: almost every week a new Java security update.
Time to update again, to stay secure and install the patch: Security Alert CVE-2013-1493.
On the funny side: Java 0day countdown.

Thanks to Matthijs ter Woord who pointed me to these.
They require a single Intel®, Nvidia®, or AMD® primary WDDM driver. That driver does the actual rendering, the USB device then gets the rendered parts over USB to the monitor.
The really cool thing is: they work on a PC with Windows XP and higher, and on Mac with OS X Tiger or better.
The chipsets are based on DisplayLink technology; they have their own USB devices as well.

Today, my MacBook Air again kept keeping the fan speed at high, even though nothing was using CPU or other power.
So I again resolved it by following: Resetting the SMC solved my MacBook Air Fan Noise With Lion problem « The Wiert Corner – irregular stream of stuff.
The not so cool thing is that this ONLY works if your Mac is connected to a Power Source.

If I read Inappropriate Use of Adobe Code Signing Certificate my conclusion is that anything signed by the Adobe Code Signing Certificate since 2012-07-10 potentially can be malware.
As a precaution, I will manually revoke the certificate on all my systems (that’ll take a while!). If anyone knows how to automate that process, please post a comment showing how to.
Hitching on a trusted certificate of a big software company comes close to the ultimate hack: trojaning signed malware in the distribution of an OS vendor.

On monday, I wrote it was Time to disable Java for a while: Zero-Day Season is Not Over Yet.
Today Oracle released a fix, which you should either install immediately (that is NOW, don’t hesitate!).
For this vulnerability, it is enough to disable Java from your browser – see: How to disable Java in your web browser – but as with any software: if you don’t need it, just disable/uninstall it.
Disabling/uninstalling on a Mac may impose a problem, as Apple hasn’t come with an update for the OS X editions that came with Java pre-installed.
Most other users can either install the version on their current system on-line from Download Free Java Software, or download offline installers for other systems at Java Downloads for All Operating Systems.
I might actually try the Java Unattended Silent Installer and Updater from Ninite – Install or Update Multiple Apps at Once.
