> Hello > > Last week, the Korean J users group had a joint meetup with the Smalltalk > users group. We chose Game of Life( > http://en.wikipedia.org/wiki/Conway's_Game_of_Life ) as a common problem > and solved it in each one's own way and then compared the two different > approaches, that is, J vs. smalltalk. > > Since there were going to be mostly novices in either of languages in the > workshop, the organizers of the two communities independently prepared a > worked example(http://en.wikipedia.org/wiki/Worked-example_effect ) for > each language before the workshop. > > Of course, the two approaches were substantially different. The J worked > example I prepared is here: > http://jaylang.org/wiki/index.php?title=%EB%AA%A8%EC%9E%8420121122 > > Even though the descriptions and instructions are in Korean, most of them > are also in J code, so you may not have much difficulty following them. > > However, I think it is important to include a translation of one of the top > paragraphs, which includes general heuristics for each implementation > step(62 currently, including two quizzes at the end): > > ========== > I recommend you go through the following activities for each steps: > > 1. Enter the line. (and press the enter key) > 2. Guess what that line just did. > 3. Based on that, make a hypothesis. (make assumptions, like it will do > such and such) > 4. Plan an experimentation, a variation from what you've just entered, > based on that hypothesis. (If I enter this, such and such result will > show > up) > 5. Conduct that experimentation and compare the result with your > expectation. > 6. If you feel confident to make a theory about it, proceed to the next > line; otherwise, go back to the step 2 above. > > =========== > > Most of the people who followed the J example could understand some of the > major ideas of J programming. They were impressed by the succinctness and > some of them felt like they are back to kindergarden students. > ---------------------------------------------------------------------- > For information about J forums see http://www.jsoftware.com/forums.htm > -- Björn Helgason, Verkfræðingur Fornustekkum II 781 Hornafirði, t-póst: gos...@gmail.com gsm: +3546985532 twitter: @flugfiskur http://groups.google.com/group/J-Programming Tæknikunnátta höndlar hið flókna, sköpunargáfa er meistari einfaldleikans góður kennari getur stigið á tær án þess að glansinn fari af skónum /|_ .-----------------------------------. ,' .\ / | Með léttri lund verður | ,--' _,' | Dagurinn í dag | / / | Enn betri en gærdagurinn | ( -. | `-----------------------------------' | ) | (\_ _/) (`-.
