Hi! We're sending this automatic email twice a month, to give the community an opportunity to easily know what's happening and to coordinate efforts. Just answer informally, and feel free to spawn discussions thereafter! ### Here's what I've been up to since the last WhatsUp: - $HEROIC_ACHIEVEMENTS_OR_DISMAL_FAILURES_OR_SIMPLE_BORING_NECESSARY_TASKS ### What's next, until 2015-03-31 (*): - $NEXT_STEPS_TOWARDS_WORLD_DOMINATION (*) we'll be expecting results by then ;)

[OT]: Fwd: Why GSoC? Why me?
by Sean DeNigris March 16, 2015

March 16, 2015

Writing the following message, which I wrote as an introduction to Fossasiaâs prospective Smalltalk GSoC students, vividly reminded me of why I love Smalltalk. So naturally, I want to share it with our communityâ¦ - Sean > Congratulations on finding Smalltalk. I doubt you have any idea how important this could be for you. > > You may not realize it, but you have opened a portal to some of the greatest minds in the history of our industry. In the beginning, for many of our heroes - Doug Engelbart, Alan Kay, Seymour Papert - computing was about the possibility of evolving the general level of human thought for the benefit of mankind. Effective critical thinking is vital to modern life e.g. the proper functioning of democratic governments. Yet traditional media have been ineffective at improving our thought on a large scale. Today, weâre mostly glorified "caveman with briefcases", reacting to the same human universals as our distant ancestors - Fantasies, Stories, Superstition, Religion/Magic, Vendetta. > > So what does this have to do with computing?! > > Iâm glad you asked :) In 1972, Alan Kay envisioned a "dynamic medium for creative thought" which he called a Dynabook [2]. It was an answer to the problem described above - a computer to support and guide minds to the level required to overcome our uglier instincts, and replace them with our highest ideas, like Equal Rights, Democracy, Slow Deep Thinking, Legal System over Vendetta, Theory of Harmony - ideas which do not take seed on their own, but must be actively nurtured. > > So what does this have to do with programming?! > > Iâm glad you asked that, too :) Smalltalk is interim[3] Dynabook software! You have in your hands, not a programming language, but a live, dynamic, turtles-all-the-way-down environment designed to provide "support for the creative spirit in everyone". > > More practically, Smalltalk is a programming tool that allows productivity unimaginable in most systems. And, if you put in enough time and effort to actually think in it, it will help you program better in any language you use. But, I think it would be a great waste if you left Smalltalk "a better programmer", when the questions before you are: > - What really matters? > - How can computers fulfill on that? > - How can I, as a programmer, contribute to that? > > Ideas for research: > - Dynabook. Any of the original documents can be found easily online, but particularly: > - Afterword: What is a Dynabook > - Personal Dynamic Media > - Smalltalk: Design Principles Behind Smalltalk > - Ivan Sutherlandâs Sketchpad > - Doug Engelbart & "The Mother of All Demos" > - Selfâs Morphic papers > > > [1] Although few answers to date have been as thoughtful and daring as LISP and Smalltalk > [2] http://en.wikipedia.org/wiki/Dynabook > [3] The Dynabook is a Platonic ideal, as so any implementation is just a step along the way in an infinite game

Loading a configuration with gofer?
by Bernardo Ezequiel Contreras March 15, 2015

March 15, 2015

Hi, the following scripts load different versions and packages of a configuration, is that ok? *** first script: loading development version of a configuration with gofer Gofer it smalltalkhubUser: 'Moose' project: 'PetitParser'; configurationOf: 'PetitParser'; loadDevelopment. ConfigurationOfPetitParser project currentVersion >=1.8-snapshot [ConfigurationOfPetitParser] *** second script: loading the configuration with gofer and then asking the configuration to load the development version. Gofer it smalltalkhubUser: 'Moose' project: 'PetitParser'; configurationOf: 'PetitParser'; load. ((Smalltalk at:#ConfigurationOfPetitParser) loadDevelopment). ConfigurationOfPetitParser project currentVersion >=1.10 [ConfigurationOfPetitParser] -- Bernardo E.C. Sent from a cheap desktop computer in South America.

PharoVM for openindiana
by Andreas Wacknitz March 15, 2015

March 15, 2015

Hi all, I decided to build a PharoVM as of today for openindiana following my notes I took last year when I did it last. For this build I am using the PharoVM sources as of today (15th March, 2015) from https://github.com/pharo-project/pharo-vm. I am bootstrapping it from my Mac. First finding: Running newImage.sh shows a problem with an outdated class in the SoundSystem which leads to the error log that I appended to this mail. The reason for this problem is an outdated class BaseSoundSystem which inherits from AbstractSoundSystem. Pharo 3.0 changed the name from AbstractSoundSystem to SoundSystem. Thus, Sound.Package (GuillermoPolito.69) needs an update. Regards Andreas

[Issue Tracker] open issues down to 644
by Marcus Denker March 15, 2015

March 15, 2015

Hi, We managed to get the issue tracker to 644 open issuesâ¦. with e.g. 60 issues closed the last 7 days alone. For one this is nice: number of issues is decreasing even though new issues are reported. Yes 644 is very high. Ca everyone please check the reports, especially you own old ones? Maybe an issue open since >12 months of the âwould be niceâ kind actually can be closed? Or things that only you care about but even that not enough to actually do something? Keep in mind that it would be trivial to add literally *thousands* of âthis looks strangeâ âmaybe this could be simplerâ or âit would be nice ifâ issues. Just that it does not help anyone, as nobody will ever do this if it is already not important enough for *you* to do. Marcus

#milliseconds versus #milliSeconds
by Ben Coman March 15, 2015

March 15, 2015

Using Finder, the majority representation in the image appears to be all-lowercase #milliseconds with only a few #milliSeconds. Googling indicates the former is usual. Is it worth logging a ticket for Pharo 5 to make the latter consistent? cheers -ben

QUESTION about smalltalkhub.com/projectList
by Esteban Lorenzano March 14, 2015

March 14, 2015

Hi, Soâ¦ I had some time this morning so I added the required /json to project list. is /json and not ?format=json because 1) it will be just one output format so no point on having a parameter, and 2) is easier to add the filter that way :) This is still NOT in productionâ¦ it will be on monday, following the advice of ânot deploying during week endsâ but nowâ¦ doing this idea came to my mind: actually, the name /projectList is bad (super bad), because it is not a list of projects, but a list of repositories. Soâ¦ I think link should be: /list ot /repositoriesList instead. It will be a lot clearerâ¦ specially because Iâm also working on a page for real projects (taken from the catalog made by Stef and Damien). So, what do you think? Can I rename the repositories list link? Esteban
