Git 1.8.5 is out

Git 1.8.5 is now out. The RC was available for more than a month, and now it’s gone stable. One interesting change is the new alias for HEAD. From the atlassian blog:

This had been cooking for a while and it’s finally in: HEAD has a new alias, instead of typing four capital letters you can say “@” now, e.g. “git log @“.

Which means you can now just type in @^ for HEAD^ and @~2 for HEAD~2 and so on.

Among other notable changes are that git-repack (which was a shell script previously) has been rewritten in C, cherry-pick shows the commits being cherry-picked and diff-filter has got an “all-but” option.

re: Why You Should Never Use MongoDB

Ayende Rahien (creator of RavenDB), replying to the post Why You Should Never Use MongoDB:

The actual details in the posts are fascinating, I’ve never heard about this Diaspora project. But to be perfectly honest, the problems that they run into has nothing to do with MongoDB or its features. They have a lot to do with a fundamental lack of understanding on how to model using a document database.

And then,

What I do know is that having a single document that large is something that I want to avoid. And yes, this is a somewhat relational model. That is because what you are looking at is a list of independent aggregates that have different reasons to change.

My knowledge of database models is too lacking to comment on who’s right. Perhaps there’s no ‘right’ way, like many things are in this field. All I can see is that with the separate-document method Ayende suggests, you can get the best of both worlds, even though it might seem like trying to make a NoSQL database relational.

But clearly I should read more. :?
