When using google to find things in the excellent Postgresql documentation, I often end up on pages showing old postgres versions.  For example, googling for “postgresql create index”, the first hit is for the postgresql 8.2 docs, and I’m running 8.4 now.  My co-workers made a greasemonkey script to automatically redirect to the current version, and I adapted that into a bookmarklet.

Drag this link into your address bar to to use it in your browser:

pg-docs

When you find yourself on a old postgres docs page, click the bookmarklet to redirect to the latest version of that page.   This should work as long as the postgres folks keep their URL naming scheme.

I really like how git tells me how many lines inserted/removed when I commit, and wanted to get something similar from Subversion.  I’m working on a refactoring of an older system, and I wanted to know how my refactorings were effecting the code.  I think I’m going to remove a lot more code than I add, but why wonder when svn has all this info?

Using my horrible bash skills and this post on SVN Line Output Totals, I came up with an inefficient bash program to do what I want:

Example:

 > svn_line_changes -r 264:265
Scanning -r 264:265
Removed: 287
Added: 141
Difference: -146
