In November a Mark Schonewille posted a blog on when you can't and cannot use the GPL version of MySQL together with your closed source application. The post was a result of actually talking to an Oracle lawyer which makes it valuable information. Unfortunately Mark's blog is now offline (it seems he didn't renew his domain registration?)
This is just a repost of the disappeared blog post. (The small print allows me to copy it verbatim.) There is no commentary from myself, except that what Mark wrote is the same I also heard Oracle say a year ago. That Oracle is being consistent on this point is very welcome and deserves to be kept available online.
Update 2011-06-23: Mark comments that his blog is still online, but at a new address: http://qery.us/tl
Last week professor Eben Moglen published an SFLC position paper related to the EU investigation on the Oracle Sun merger. Even though most of the proceedings do not happen in public, the SFLC publishing its own paper allowed us to answer it to the Commission. While it is not our primary objective - and we are a bit constrained at this point - to educate the public or debate this. But given that it is something everyone likes to have an opinion on, and the SFLC has already opened the discussion, we have decided to also publish our submission as well.
We would like to emphasize the following paragraph from the introduction.
Bruce Perens has nominated himself to become a board member of the Open Source Initiative. To get there, the OSI board (which elects its own members) has said he needs to show he has support in the Open Source community. If you want to show Bruce your support, you can do it here: http://techp.org/p/7
This blog is supposedly at least partly about Open Source business models. Here is a LinuxWorld interview with Matt Asay about many interesting actions taken in running Alfresco as an Open Source company. While this is a must read for anyone doing Open Source business, I'll summarise the key points here. (The article is rather long, but again, everything is worth reading.)
