Hey Tim, Your emails aren't getting posted to the users list, only the nabble forum. Are you a subscriber?

Programming Puzzles & Code Golf: What color is this?

by MartinW

Hi, i entered a Pharo version to this Code Golf contest: http://codegolf.stackexchange.com/a/32535/26615 "Given three number values - being the Red, Green, and Blue elements of a colour (eight bits per channel, 0 to 255) - your program must output the name of the given colour.â My answer is: | color colorNames nearestColorName | color := Color r: 255 g: 0 b: 0. colorNames := Color registeredColorNames. nearestColorName := colorNames detectMin: [ :each | (Color named: each) diff: color]. But, the results are of mixed quality. All darker colors are named as gray, dark gray or very dark gray. Is it my fault, the fault of Colorâs diff: method or the fault of the available color names?

Re: [Pharo-users] A question about sets

by Alain Busser

About the birthday problem, I already pulished something that I had exeperimented in the classroom, but it is in French: http://irem.univ-reunion.fr/spip.php?article618 (clic on "problÃ¨me des anniversaires" tab). The idea is that if you add say 30 times a "365 atRandom" to a bag (instead of a set) it happens now and then that a number appear more than once. In this classroom, two students actually had the same birthday, and they were eager to know of it happens often, so that they were very active for this exercise.

Re: [Pharo-users] ZnClient get then post?

by Paul DeBruicker

Are you able to get the contents of ZnEasy get: 'https://www.google.com' ? If so then is not an SSL issue. If not you'll need to use charles proxy (http://www.charlesproxy.com/) or an equivalent to see the decoded https requests. Wireshark only has encrypted packets. Are you doing the #resetEntity prior to setting the url or other parameters when doing your POST?

[Tutorial] Rediscovering the UX of the legendary HP-35 Scientific Pocket Calculator

by Sven Van Caekenberghe

Hi, I have written a new, extensive, long form, introductory article about Pharo. Rediscovering the UX of the legendary HP-35 Scientific Pocket Calculator A tutorial on Pharo, test and specification based immersive programming https://medium.com/@svenvc/rediscovering-the-ux-of-the-legendary-hp-35-scie… It is a bit different because - it is based on a non-trivial example - it uses a backdrop story unrelated to Pharo - it uses several multimedia elements - it is published on medium.com which is a general publishing platform The appendix describes several ways you can get the code. I think building both a Spec and Seaside UI from the same specification as well as reusing functional tests in different contexts is cool. Anyway, I hope you enjoy it.

Re: [Pharo-users] ZnClient get then post?

by Paul DeBruicker

Do your query parameters from the initial GET get cleared from the request before the POST? If you're not sure send the client #resetEntity. Is the response of the GET correct & are the keys decoded properly? if not can you get a valid signature and request key from somewhere else (e.g. web ui, or ....) to test the POST? Is it important to reuse the connection? IF not add the #beOneShot method to both and see if that helps as it does some resetting. The #post method is a convenience method that conjoins a send to #method: and #execute. You could separate them and use #method: at the top and #execute; before the #request line but I'd be surprised to learn that fixed things.
