New Jupyter notebook host - Gryd

[Joe Gamman]

Hi All,
Just a heads up I found this today which seems to be pretty new and in beta: https://gryd.us/

i just signed up and it seems to do what it says on the tin.  could be useful for those of you wishing to teach a class where some of the students can't get their Anaconda install working.  it appears to be in beta so i guess you get what you pay for...

Some of us at https://CoCalc.com did some poking around and noticed
the following about gryd.us, in case it is of interest:

"I did play around with them for a while. Looks indeed interesting,
they also just offer the classical jupyter interface, but at least
they've enabled various extensions and seem to also have a strong
focus on teaching.

I'm also always curious about what's under their hood regarding
software. It surprises me that they run a rather old debian jessey
linux, only have tensorflow 1.3 in anaconda, etc. Maybe a bit behind,
but at least it is working.

They say in their free version the cpu is limited. I should run some
sort of benchmark to see if they run it at 50%.

ok, I don't see any 50% cpu capping, but ok, the load is also almost
zero. so maybe they share cpu like we [CoCalc] do and then it's going
to be slower.

Here is publishing a worksheet:
https://beta.gryd.us/notebook/published/ha_sch/py3.ipynb

Seems like they run nbconvert with a template. Also, I noticed that
changing the source file and saving it doesn't update this shared
file. I even waited a minute or two. Unpublish/publish did the trick.

ok, finally some hosting info. looked up their IP (they allow outgoing
network traffic): 54.87.201.190 which is amazon AWS.

The VM I happen to run on is a 2 core Intel(R) Xeon(R) CPU E5-2666 v3 @ 2.90GHz

They also use containers, because I only see this is running and the
notebook has PID 1.
