Be thankful for Notes / Domino backward compatibility


At one point about 6 years ago we had looked at developing part of the business around using opensource systems like Joomla for collaborative applications ( the push being a frustration with IBM licensing ). We set up some sites for local charities as a way of dipping our toe in the water.

All my spare time ( and more ) is now going into fixing these charity websites that we set up and support for free or for a nominal fee – its a bit of a nightmare really 🙁  

The sites are on a version Joomla ( originally Mambo ) which is no longer compatible with the version of PHP that the web hosting provider has upgraded to and they have all fallen over.

The learning that we took away fairly quickly ( and hence stayed with Domino ) was that managing the core opensource module and the different plugins connected to that module is very difficult, particularly where each project was bespoke

The key issues were :

>>>Upgrades to the core Joomla / Mambo system would sometimes break the separate opensource extensions.

>>>In many cases the upgrade cycle of the extensions lagged behind the core Joomla upgrades.

>>>Backward compatibility was not a high priority in the project with 3 significant changes in architecture.

>>>The opensource project forked at one point ( the Joomla / Mambo split ).

>>>Hacking was a more difficult  issue to manage than on a Domino platform

The Joomla project is hugely impressive. What has been achieved by this opensource project is just amazing and I still remember the first time I looked at the Joomla Application Control Panel thinking that if we had been asked to write it from scratch it would have been a
