If you are using the Eclipse Modeling Framework (EMF) standalone, i.e., you are not running it in an Eclipse-based environment, and you want to use OCL, some additional steps have to be performed besides registering your resource factory.

If you either received a LyX file that uses a document class unknown to your LyX installation or you would like to create a document using one of the options in the settings dialog, you need to install that document class.

When connecting to the database with the postgres user I realized it accepts any password or no password even though the user has a password set.
I don't know if this happens also when using the installer to install PostgreSQL.
In my case I used initdb to set it up.
I remember it mentioned something regarding "trust" after setting it up but didn't take much notice until I realized it accepts any password.
In pg_hba.conf it adds all local connections to be trusted which means connecting from the same host doesn't require authentication.
If you don't like that just change it to another method.
svn+ssh protocol and a putty profileThis post is archived. It is left as is and won't receive updates.
When trying to access an SVN repository using the svn+ssh protocol with TortoiseSVN it might happen that the password prompt shows up endless times.
One suggested solution is to set up a profile in putty and use a private key for authentication for SSH there.
Then in TortoiseSVN the host name just has to be changed to the name of the profile, e.g., svn+ssh://username@puttyProfileName/path/to/repo.
This works well until trying to reuse the stored SVN information of your local working copy in another client, for example your IDE. In my case I am using Eclipse with the Subclipse plug-in, and my first approach didn't work with Subclipse. This meant I couldn't do any team actions from within Eclipse when the projects where checked out using TortoiseSVN. If you are only using either of them it works fine.
The solution is quite simple: Rename the putty profile to the actual hostname and use the regular URL for the repository. That's it. If you've used the putty profile name before just use relocate in TortoiseSVN to change the repository URL. TortoiseSVN will then still use the putty profile with the private key to authenticate. Other clients like Subclipse see it as an actual hostname and are able to use that.

If you—for some reason—don't like the yellow (for contacts in your address book) or gray (for unknown contacts) star next to email addresses in the message header there's a simple way on how to hide it.
If you don't have one yet, all it needs is a file called userChrome.css inside a folder called chrome inside your profile folder.

After updating my Thunderbird to the current version there was one extension not working anymore: Headers Toggle.
Even manually adjusting maxVersion in the install.RDF to pretend it's compatible didn't work.
This extension allowed you to switch the headers view between seeing all headers (All) and the most important header information (Normal) with a single key shortcut H.
Unfortunately this extension hasn't been updated in a long time.
I created a new Thunderbird extension called Toggle Headers that allows you to do this and works with the current (and upcoming) Thunderbird version.
Update: The newest version (0.3) of Toggle Headers is compatible with CompactHeaders.
When both are used at the same time the current state of the headers view is taken into account:
