[sage-support] Re: Unable to check out trac tickets
I followed the instructions on https://stackoverflow.com/a/18238322 and it
seems to be working so far. I lost all my local branches, but I don't mind.

[sage-support] Re: Unable to check out trac tickets
This error with "garbage at end of loose object" is coming back to plague
me. I recently tried to upgrade sage by pulling the develop branch, but I
couldn't.

What can I do, short of deleting everything and cloning the entire

[sage-support] Re: Calling java classes from Sage using Py4J
In Sage, "10" is a Sage integer, not a Python int. I am guessing that gateway.jvm.java.util.Random.nextInt expects a Python int for its input, and when it gets a Sage Integer, that causes a problem. What happens if you replace "random.nextInt(10)" with "random.nextInt(int(10))"?
