Eric's idea sounds doable based on what I already know. I'll take a look at Joe's suggestion as well. On Mon, Mar 24, 2014 at 11:43 AM, Eric Iverson wrote: > I think the best is if you can get individuals to install their own > copy of J. Then they have something to take away and that is good.

I think the best is if you can get individuals to install their own copy of J. Then they have something to take away and that is good. A web route is to get a free cloud machine (amazon whatever) and install J. Then ssh to the machine and run a script to create 30 (whatever) JHS instances with por

One potential problem with JHS is that the state is shared across all users (as far as I know). So you'd need to have them work in their own locale or something. Perhaps you can just bring a laptop and open up JHS for the students to use? If you were concerned about security, you might want to run

Note that I've been operating a batch of AWS linux machines (working with Skip). This is the EC2 service, and I've been using 64 bit debian instances. That said, there's a variety of providers of machines (other than AWS - hostgator, linode, digitalocean, ...), with different billing and support m

I think a public or semi-public JHS would serve well for any sort of "Introduction to J" workshop. One of the things I got out of the education workshop I attended yesterday is the teaching pattern of "I do"-"we do"-"you do": where I (the instructor) demonstrate something, the class works on an ex

A good practice is to install J on all pcs in public places and in schools. Now it is possible to use tablets and the price of tablets is good. It is brilliant to be able to run demos and labs so the beginners can get a feel for the power of J without knowing much and can get their own to learn m

Another option would be installing J on a linux machine, and let your students log in using SSH. But this is of course CLI-only, unless they have an X server installed (Xming is recommendable for windows). Kind regards, Jan-Pieter On 23 Mar 2014 17:36, "Skip Cave" wrote: > Amazon Web Services

Amazon Web Services has a free virtual micro instance you can use. I think it is free with a new account for a year. After a year, it costs 2 cents an hour, 48 cents a day, $15/mo, $174/year. Other more powerful options are available, but they don't have the first free year. Here is AWS pricing

I'm in a teaching workshop in which we should present an example lesson plan at the end. I'd like to do a J example but really need to allow people to do hands-on usage and it's probably too much to ask for everyone to install J but, if there were a website to which I could direct people, it's mu
