New random generator
by stepharo March 20, 2015

March 20, 2015

Hi guys Konstantin who is a biologist developed for a "bacteria" eating monster simulation system, two new random number generators. I think that this is great because we need more random generators :) - Combined Random Number Generator is based on the algorithm described by PIERRE L'ECUYER in "Efficient and Portable Combined Random Number Generators" [Communications of the ACM, June 19, Volume 31, Number 6, pp. 742-749, references p.774]. - ExpInvConGen is an explicit inversive congruential generator, constructed according to "Good random number generators are (not so) easy to find" by P. Hellekalek (1998) and extended euclidean algorithm. I plan to package them and publish them in SciTalk with their own configuration. But I wanted to know what you think. Stef

SystemBrowser feature request / bug report
by Sebastian Heidbrink March 20, 2015

March 20, 2015

Hi! I think it is a mix of a feature and a bug. When ever one implements a Magritte, Moose or Morphic project the functionality to select the package list and enter/hit key "m" does not fast scroll down to those packages but rather selects the "Most Viewed Classes" entry. I propose to catch "m" and ignore "Most Viewd Classes" for this fast scroll/find functionality. Sebastian

practices in storing users application level variables
by Sanjay Minni March 20, 2015

March 20, 2015

Hi What is the usual practices in storing values of variables / parameters the persist through an users usage of an application. e.g. say the user logs in and then selects a current printer, current company, accounting year and then moves between various application options and eventually logs out. What is a good practice of storing the values ... one way could be to keep a separate application level object with a dictionary for all the variables ... would that be ok or there are other better ways regards Sanjay ----- --- Regards, Sanjay -- View this message in context: http://forum.world.st/practices-in-storing-users-application-level-variable… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

searching for protocols
by Peter UhnÃ¡k March 20, 2015

March 20, 2015

Hi, is it possible to find which class uses particular protocol? Typically I am not sure how to name a protocol so I would like to check out other classes. For example the system offers me to name protocol as "enum primitives" but I don't know who uses it and for what exactly. Thanks, Peter

Aconcagua Documentation
by Sean P. DeNigris March 19, 2015

March 19, 2015

Is there anything besides http://stephane.ducasse.free.fr/Teaching/CoursAnnecy/0506-M1-COO/aconcagua-… ? There are not many class comments and the tests were a bit overwhelming for me... Specifically I'm searching for anything built-in to present measures in the "most tidy" representation e.g. "125 dollars" instead of "12500 cents", "10 cups" instead of "480 teaspoons", etc. ----- Cheers, Sean -- View this message in context: http://forum.world.st/Aconcagua-Documentation-tp4759781.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Chalten: Month and Year Units
by Sean P. DeNigris March 19, 2015

March 19, 2015

I guess they aren't derived from each other because e.g. the Hebrew calendar has leap months. But doesn't that just mean that "Month" is representing two incompatible distinctions? It seems we should be able to distinguish "1 gregorianYear = 12 gregorianMonths" from "1 hebrewYear convertTo: months" which is an invalid question. Right now, one can't ask "1 yearMeaure / 12 monthsMeaure" and get 1 ----- Cheers, Sean -- View this message in context: http://forum.world.st/Chalten-Month-and-Year-Units-tp4813273.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Get OS uptime
by Julien Delplanque March 19, 2015

March 19, 2015

Hi everyone, I can't find out how to get the uptime of the OS from pharo. I tried: (FileLocator root / 'proc' / 'uptime') readStream contents. and (FileSystem disk root / 'proc' / 'uptime') readStream contents. but all what I get is an empty string ''. I don't know if there are messages in some specific classes to do this (in OSProcess for example?). Thanks in advance. Julien
