Rapache on Ubuntu 9.10

November 15, 2009

I’ve just now stumbled across Rapache, a useful GUI tool that makes configuring apache easy. I found it by accident in the Ubuntu Software Center, but unfortunately it would freeze while trying to add a new domain. I searched the web for answers, and found a bug report.
This didn’t specifically reference Ubuntu 9.10 (rather, 9.04) [...]

Just for a bit of fun… whohasmorefollowers.com

May 4, 2009

Recently I jumped on the Twitter bandwagon and created whohasmorefollowers.com - a simple service that lets you compare the number of followers for 2 Twitter users.
This weekend I added a game feature to it - the player is presented with 2 random twitter users (from the top 50) and is challenged to guess which user [...]

Redirecting javathinking.com to www.javathinking.com

April 18, 2009

I thought it would be a good idea to redirect requests to http://javathinking.com to http://www.javathinking.com and I found out how to do that easily here.

RewriteRule ^(.*)$ http://www.javathinking.com$1 [R=permanent,L]
In ISPConfig this can be done easily through the administration console rather than editing the apache config [...]

No Dialect mapping for JDBC type: -1

April 23, 2008

This Hibernate error came at me out of the blue while working on FilmSuggestions.com - I innocently added a constraint to one of my Grails domain models, setting the maxSize of one of the fields to 2000. This changed the table schema making the column type TEXT instead of VARCHAR.
The problem came from a native [...]

Firefox profiles

March 16, 2008

If you share a login with someone else (ie. family) Firefox profiles can be very useful. Likewise, if you are a developer and you have several different contexts or modes of operation, profiles can make life a lot easier.
I use them at home with family members - you can set each person up with their [...]

creates a new grails app
copies preprepared resources into this new grails app
installs the plugin

Now all I have to do is run the application and [...]
