Re: [Jprogramming] J in 5 minutes

Well done Martin, Really high production values. I do think that you could afford to enlarge the workspace window to allow the text to appear larger as the background is not so necessary. You did a great job of setting up your context and letting the viewer know what you were going to cover.

Re: [Jprogramming] J in 5 minutes

I agree with Joe, that is a fine demo of J. It is long enough that you might want to include a table of contents in the details. For example, this was how I did it with another video. Introduction: http://www.youtube.com/watch?v=wXjlDUGDXDw Install/Launch JHS on host computer: http://www.youtube.c

Very impressive. I was watching the clock in the upper right corner and it seemed like it all happened in real time. If that's the case, your typing is impeccable! Regardless, great demo. The collatz conjecture was very interesting. I had never seen qjide in action so I'll have to experiment with

Pascal, I can't remember the sequence of emails, but I do remember asking in a relevant thread if anyone had found a way to make a grid into active cells accepting excel-like formulae, with the idea that many people would find the transition to J easier if that were possible. And if memory serves

Old OpengGL (1.x) is still supported on J8 if viedo card OpenGL driver is opengl 1.x or it provides compatibility profile. Some minor code modification is needed, please see jwiki and various opengl demos in qt demo and wd demo. OTOH webgl must use shader language IIRC. Сб, 22 фев 2014, Raul

Re: [Jprogramming] J in 5 minutes

Talking about issues (as opposed to coding itself) probably belongs in chat forum, not programming. We should try to make sure that programming forum messages always includes some J expressions. And not just "sarcastic" expressions like =i.9 Ideally, in programming forum, we should also try to i
