Jumi and Joomla 1.7 installation fix


Jumi is a handy Joomla extension that lets you include arbitrary code in Joomla without messing around more than you have to. I recently upgraded a client's install to Joomla 1.7.3 and tried to install Jumi, but got the following error:

Warning: constant() [function.constant]: Couldn't find constant JPATH_ in .../libraries/joomla/installer/adapters/module.php on line 115
Module install success
Plugin install success
Router install success

The extension mostly worked, but translations were missing. To cut a long story short, after some scraping around I found that the problem is fixed in Jumi 2.0.7, which is the version shown on the download page and the version I thought I'd downloaded. It turns out that the download link actually points to 2.0.6, which doesn't work with Joomla 1.7. I checked the trunk version in the SVN repository and it's tagged 2.0.7, so I tried it out and installation was flawless.

I can write code nao?


The NAO H25I've recently had the honour of being accepted onto the NAO robot developer programme. I'm more than a little excited. The NAO is an awesome little robot produced by the French company Aldebaran Robotics. It's designed for a wide range of uses and is available to educational establishments, RoboCup teams, and selected developers(!), with a planned public release in the next year or two.

The NAO is one of the most advance humanoid robots in the world and is pretty dexterous. Want it to dance? No problem! Do a little Star Wars reenactment? Easy! But with speech and face recognition and motion control built in as standard the Nao can do far more than just repeat a set of pre-programmed motions. The official development programme video has a few ideas. I think it can do more.
