JuliaBox for Coursera

[Juan Klopper]

Viral,

The gremlins just don't want to go away.  We now have two beta testers (and Coursera will also put people through the course this week).  Locally that makes seven people and we are all having issues with JuliaBox.com.  I'm talking about vanilla runs, simply adding packages through the console.  NOTHING fancy.  Probability would suggest that we can't be an isolated group.  What are you seeing on your side?

On my Mac OSX 10.11 I seem to have no problems.  Some Linux and Windows machines (and other Macs as well) seem to show this as a recurrent theme when doing a simple Pkg.update():

julia> Pkg.update()

Out of memory errors are the second most common problem.  At times a rm -rf ~/.julia fixes the issue.  Once one or two packages are installed (remember we only require Plots (pyplot and plotlyjs backend), DataFrames, Distributions and StatsBase), the problems start.

Are we seeing isolated problems?

Can you email me - off-list, the email accounts of the folks who are facing this. Does wiping the packages help?

Also, are you using 0.4.6 or 0.5?

Also, I believe many of the packages you need are already installed. These signs seem to be of directories that are over quota (500MB). And if you do Pkg.update(), it takes up quite a bit of that.

Can we fix a time for tomorrow and do a Google hangout to see what is happening and troubleshoot in real-time? I tried all of this and much more and it is quite stable for me.
