How do I debug error ECONNRESET in Node.js?
...n Node. I believe this is intended functionality for Node, so the fix (at least for me) was to handle the error, which I believe you did in unCaught exceptions. Although I handle it in the net.socket handler.
You can demonstrate this:
Make a simple socket server and get Node v0.9.9 and v0.9.10.

This is doable, at least in theory, if you know the index:
System.out.println(team1.keySet().toArray()[0]);
keySet() returns a set, so you convert the set to an array.
The problem, of course, is that a set doesn't promise to keep your ord...

Selecting multiple columns in a pandas dataframe
...l, slicing with labels in Pandas is inclusive of the slice endpoint (or at least this was the behavior in most previous Pandas versions).
