Earlier this year, Sagemath Cloud went into open beta so anyone can play around with it. If you’re not familiar with the service, it’s a free cloud-based web service that provides access to personal directories, a terminal, IPython Notebook (incl. Rmagic), a LaTeX editor, compiler, & viewer, and so much more — all from the web, so no installation required!
I see this tool being revolutionary not just for research collaboration, but for teaching as well. Imagine live coding with a class and having the code appear right on their screen as you type it. Even better, imagine not having to go through the installation process on several different operating systems every time you teach a new class.
I ran across Sagemath Cloud last month and have been using it to collaborate with my mentees ever since. Since I have a bit of experience with it, I’ll provide an overview of what you can do with Sagemath Cloud below.
Disclaimer: I don’t work for nor with the Sagemath Cloud folks, I’m just really excited about this service!
All the basics
Of course, Sagemath Cloud has all the basics. It has a directory structure for you to upload and organize your files and a terminal to run programs and scripts as you please.
With the click of a button, you can start up an IPython Notebook and start coding away. They seem to have all of the standard scientific computing libraries installed already. I was able to replicate my Python stats tutorial without a hitch.
They even have the IPython magic libraries installed, so I was able to replicate my Rmagic IPython tutorial and run R code in the IPython Notebook as well.
They don’t have all Python libraries installed yet, and it doesn’t look like you can install your own libraries just yet. I’m sure they will install libraries by request however. It’d be especially nice if everyone could have their own Python installation and install any library as they like.
Edit: Apparently it is possible to install your own Python libraries. See Aron’s comment.
Sagemath Cloud lets you upload files directly from the web, so if you’re writing a PLoS article, you can upload the template to Sagemath Cloud and immediately start editing it from there. You can do this with IPython Notebooks as well, so if you find a notebook on the web that you want to hack away on, just upload the file from the URL here.
Even better, Sagemath Cloud has a built-in LaTeX editor, compiler, and viewer. My lab has been paying for this service at ShareLaTeX, but now it’s completely free here.
Live editing and collaboration
One benefit of working on the web is that multiple people can work on a document at once. Sagemath Cloud makes this happen for all of the services it offers, including LaTeX.
Everything has been fairly run-of-the-mill for people who are familiar with these kinds of web services so far, but the following is what really sets Sagemath Cloud above the rest for me. You can write and execute code live with others on the same IPython Notebook.
My mind was blown when I saw this feature. This is a feature I’ve wanted for IPython Notebook ever since I started using it. The future is here, folks!
Another benefit of working on the web is that you don’t have to worry about backing up files. Sagemath Cloud takes care of all that for you and makes frequent snapshots of your working directories so you can return to previous versions of your work without a problem.
Remember: Sagemath Cloud is in beta testing
I’ll end this with the note that Sagemath Cloud is still in beta testing. That means it won’t always run perfectly, probably has some bugs, and may even crash sometimes. It’s not intended for production use yet, but it will eventually have buy-in options to have priority access to the service. Make sure to report any problems you run into to William Stein.
