Issues on Ubuntu 14.04/Anaconda

[tildebyte]

I don't know if you'd like me to open a separate issue for each bullet point...

• OOB, requires libXrender and libfontconfig (documentation issue).
• pip install --update skulpt-kernel doesn't work:
  • "no such option: --update"
• pip install --upgrade skulpt-kernel doesn't work:
  • "Could not find any downloads that satisfy the requirement skulpt-kernel No distributions at all found for skulpt-kernel"
• Downloading the github tarball and manually running python ./setup.py install completes without error, starting ipython NB server works, starting a new Skulpt notebook works, and executing Python code "works", but...
• Nothing happens, other than the Canvas #foo: output

EDIT: derp As stated, Ubuntu Server 14.04 running on EC2 Continuum's Anaconda-2.1.0-Linux-x86_64 iPython 3.0 Latest meta-kernel & calysto installed via pip

OTOH, I feel compelled to say - Holy smokes. Amazing work. I've been contributing to the Processing.py project (mostly porting over existing Java Processing examples), and this is veeery nice. I'm not a huge fan of the Processing IDE...

Thanks for the issues, and feedback!

The --update command should have been --upgrade... that has been corrected on the different README.md pages now.

The skulpt-kernel is still underdevelopment; we'll get that in pypi as soon as it is a bit more stable. But you should be able to see something if you install from git. Do you have errors in your JavaScript console?

Ah. Mixed content error, probably.

Yup. Enabling mixed content makes it all go away ;)

How do you enable mixed content?

[tildebyte]

In Firefox: click on the shield icon to the left of the address bar. You should see "Insecure Content" with a dropdown next to it. The dropdown has one item: "Disable protection". i.e. this is a browser-side "fix", not server-side.

Ok, thanks.

What were you attempting to do that needed libXrender and libfontconfig? What was the error?

[tildebyte]

It was from ipython when first opening a skulpt notebook: /home/ubuntu/anaconda/bin/python: libfontconfig.so.1: cannot open shared object file: No such file or directory and then /home/ubuntu/anaconda/bin/python: libXrender.so.1: cannot open shared object file: No such file or directory

[tildebyte]

So, from what I gather, if the js blobs (skulpt.min.js, processing.js etc.) are made available via https, the mixed content issue should go away.

Thanks for the hint on the https. I'll try to find someplace to host those supporting https.

Github supports serving javascript via https. I have updated kernels for Skulpt Python and MetaKernel Processing. Both languages now should work without having to allow mixed content.

I think all of your issues here have been addressed. Thanks again!
