In light of the various proposals regarding J-in-5, my contribution seems very tangential, but there may be an audience for this approach as well. Initially I envisioned a screencast, for the essay, but have had some difficulty with producing the screencast and have elected to make a jwiki entry.

Hi Brian, I think that tangents are not a bad thing if it allows us to get the message across in a more precise way. With the jwiki entry, I am wondering if it may be a good idea to play a little more with the tool that you have built. It seems to me that if I am a viewer who is really

If you think you could introduce that adverb without overwhelming the viewer, then I do think that kind of flexibility would be a real motivator for learning J, but I must emphasize that I am not within your target audience so take my feedback with a bag of salt. Cheers, bob On Feb 21, 2014,

I'm confused! I assume that the annual payment against the $1 loan is $1000. Which means that the value of the loan must be more than $7000 as only $3000 has been paid against it. Yet the line which should be the value of the loan after three years shows $3711.05. I think the description of

Talking about present value or getting a promise of something in the future. It is not just interest rate but also inflation you need to think about. Not to mention broken promises and not paying back in the future. Bring in the value of a hamburger now or in the future or a painting or gold.
