Atlassian, one of the most famous software companies producing useful Java web applications such as JIRA, Confluence, FishEye, Bamboo, Clover and so on, now offers Confluence (Wiki) and JIRA (Issue Tracking System) with five dollar license for small teams. Compare with the original prices of Confluence and JIRA, it is a very exceptional deal, and I think this is just good for small development teams with five or fewer members. However, it is available only for five days (20th ~ 24th, April) so if anyone needs it, had better hurry up.
Atlassian, according to the blog linked above, will donate all the proceeds from this event to Room to Read in order to help them build libraries for children in developing countries. What a nice company! I would like to work for a company like this. Atlassian also gives free licenses for their software products to non-profit organisations and open source projects which is, I believe, another way to make the world better.
