CSS for grabbing cursors (drag & drop)
... over the background. The -moz-grab and -moz-grabbing CSS cursors are ideal for this. Of course, they only work in Firefox... are there equivalent cursors for other browsers? Do I have to do something a little more custom than standard CSS cursors?

Why do I need to explicitly push a new branch?
... the same name! Tracking or not)
That means your local first push has no idea:
where to push
what to push (since it cannot find any upstream branch being either recorded as a remote tracking branch, and/or having the same name)
So you need at least to do a:
git push origin master
But if yo...

Which Eclipse files belong under version control?
... where we have the .project and .cproject files under source control. The idea was that settings related to library paths and link directives would propagate across the team.

git diff shows new and deleted files by comparing them to /dev/null. It shouldn't be too difficult to write something (I'd use Perl myself) that looks for /dev/null and filters...

Data containers don't have any meaning and are really bad idea! Container only means something when a process is running in that, otherwise it's just a piece of host file system. You can just mount a volume with -v that's the only and best option. You have control over the filesyste...
Why should weights of Neural Networks be initialized to random numbers? [closed]
... We should also note NNs are almost never convex - so the randomization is ideal way to go - but if you have a convex loss function, then of course it does not matter what you initialize your weights to.
