What a great graphic. Click it to get to the original post.
I love both the art and the message in sinfest, this sunday’s strip was just awesome:
Here is some in progress shots of the minis I’ve managed to paint so far. My skill level is still low, but I’m learning quite a bit with each new model I tackle. Enjoy.
This is Betelgeuse, which is one of the brightest stars in the night sky (9th brightest over the entire sky). It is the shoulder of the constellation Orion. Betelgeuse is notable for a number of reasons, the first of it is one of the biggest super giants you can see in the night sky. The radius of Betelgeuse is thought to be roughly twice that of the orbit of mars. It would fill up the entire inner part of our solar system. So even though Betelgeuse is 640 light years away, in the largest telescopes we’ve got you can see it as something other than just a point of light. (Previously hubble did this at much less resolution).
This latest image shows the extremely curious fact that Betelgeuse is not symmetric. It is known that it is in the death throws of the stellar life cycle (which takes tens of millions of years), blasting out bits of it’s atmosphere, however up until this point, that was not directly visibly observable, and thought to be a more symmetric thing. This image is amazing for a number of reasons, not least of which is both confirming, and putting a new spin on, the process by which a star dies. And it’s just gorgeous. What amazing wonders the night sky holds.
Yesterday we completed the transition of OpenSim from subversion to git as our primary source code system. This had actually been kicked around as an idea for nearly a year and a half, but our gating factor had always been that git support on windows was lacking. Recent dramatic improvements with TortoiseGit took away that blocking element.
One of the reasons for this move is to make it easier for more people to participate in the project (I’ve written about this in the past). The OpenSim core team has now grown past 20, and even coordinating changes among ourselves has become challenging. Subversion is fine as long as only a couple of people are working in a particular area, past that it doesn’t do you any favors in merging in complex changes. A number of complex refactorings in the OpenSim tree have been on more or less perpetual hold because of some of these svn challenges. Hopefully this will help grease the wheels there.
With git the hope is to give us some tools that help us in a number of ways. The first is to make it easier to collaborate on more complex work. The second is to make it easier for non core contributors to contribute substantial work. The ability to have an opensim clone with changes in it staged for upstream inclusion, and have a core member be able to directly pull those changes, should be a big help.
All changes come with challenges. The most visible is the lack of a monotonically increasing version number. Git changes are stored differently, so the version identifier is a SHA1 hash. That’s going to be the first big mental change people will need to get past. It seems like a deal breaker before you’ve used it, but don’t worry, it will be ok once you have gotten used it to. It’s just different.
