Re: [julia-users] Julia text editor on iPad?

[Rob J. Goedman]

Thanks Viral,

Let me know if I can be of any help testing a newer version of Jupyter (if 
installing a newer version is feasible and not too time consuming). Or I could 
point my iPad to a test version, whatever is easiest.

As far as testing dedicated compute engines is concerned I am also very 
interested, not just for Stan, but more so for some components of item 3 in 
below’s postscript

Inspired by another utopia thread on this list, the dream here is to make this 
awesome tripleJ-some (Julia, Jupyter and Juliabox) a solid foundation for 
cloud-based EDx courses.

Regards,
Rob

Re: [julia-users] Julia text editor on iPad?

[Jon Norberg]

I mentioned a few issues on the Jupyter group regarding iPad usability, such as 
kinetic scrolling and some issues mentioned above. It's working ok, but a few 
things are still awkward for ipad

Re: [julia-users] Julia text editor on iPad?

[Viral Shah]

Perhaps we need to update to a newer version of Jupyter for the arrow keys?

On the reliability front, Sheehan can you tell us what kind of instabilities 
are you facing? We are quite keen to make this reliable, and generally there 
are thousands of sessions every week. The sessions are retstricted for memory 
and compute, and time out after 4 hours - so perhaps that is the instability 
you may be seeing.

For serious computations, we are soon going to launch a service that gives you 
dedicated compute machines (no sharing or multiplexing). Would be great if you 
can try it out.

Re: [julia-users] Julia text editor on iPad?

My apologies. The remark on the arrow keys is not correct. I should have gone 
to try.jupyter.org before sending the email.

From that site the arrow keys on the iPad work fine!

Viral or Tanmay, could this be specific to JuliaBox?

Re: [julia-users] Julia text editor on iPad?

[Rob J. Goedman]

Sheehan,

Interesting link to computableapp.com. 

Have you ever seen the arrow keys work on IJulia or JuliaBox? I’ve certainly 
seen them work in other apps, e.g. Textastic, just not in IJulia. My guess is 
that the key codes have changed. Neither do they work on the older bluetooth 
keyboard. This is more a Jupyter issue than an Julia issue I would expect.

For serious computation JuliaBox is probably not the answer, but for less 
demanding situations (classroom experiments, teaching Julia, exploratory 
programming) it should work reliably. I wonder if we could confirm your Amazon 
maintenance assumption as in July I’ll be traveling in Europe and will 
certainly try it throughout the day. Could it also be network issues?

It works on the smart keyboard for me.  Otherwise, you have to press the “play”

SageMathCloud doesn't seem to work that well on an iPad, unfortunately 

Re: [julia-users] Julia text editor on iPad?

[cdm]

an alternative to JuliaBox is the SageMathCloud:

there are members servers available

The arrows sometimes work for me…and sometimes not.It’s too bad the native 
IPython app didn’t survive:

http://computableapp.com

The biggest problem I have is that JuliaBox still doesn’t seem very reliable.  
This may be since Australia is the middle of the night in the US, which Amazon 
may feel is an appropriate time to do server maintenance.   

I wonder if buying a personal Amazon Web Server is a better idea, especially

Re: [julia-users] Julia text editor on iPad?

[Rob J. Goedman]

Yes, that definitely works.

I actually bought the iPad Pro + keyboard + pen to make JuliaBox better usable 
on an iPad. And that certainly is the case for me, I can now try Julia 
constructs while on the road. Just having easy access to Shift-Return was key 
to me.

The combination of Juliabox + uploads from iCloud (or Dropbox or Google drive) 
also is nice.

A minor inconvenience is that the 4 arrow keys on the Pro keyboard don’t work, 
in those cases it’s ‘back to the pen’. 

It took me a while to discover for e.g. \lambda-Tab the Tap needs to be 
Option-Tab.

Re: [julia-users] Julia text editor on iPad?

Coda looks promising 

https://panic.com/coda-ios/

I'll look into whether it's possible to make a Julia syntax mode. (Hopefully 
the format is similar to SubEthaEdit.)

[julia-users] Julia text editor on iPad?

[Sheehan Olver]

Anyone know of a text editor for the iPad that supports Julia syntax 
highlighting?  I guess ideally this could link into JuliaBox (or another 
SSH server) so that code can be run in Safari/SSH.

(Just got the iPad Pro + Smart Keyboard and it seems fairly useable for 
on-the-go programming...)
