Monticello browser question
by Werner Kassens May 15, 2012

May 15, 2012

Hi, after having loaded some packages (dont remember which one was responsible), i noticed the package-type git could be added as repository in the monticello-browser. this leads me to the question whether i could add a repository on a github site directly, so that i dont have to clone that site first to my disk, before i can load a package? werner

#allSendersOf:inPackageNamed: vs. #allCallsOn:localToPackage:
by Helene Bilbo May 15, 2012

May 15, 2012

In SystemNavigation, what is the difference between #allSendersOf:inPackageNamed: and #allCallsOn:localToPackage: ? Is there a reason to prefer one over the other, when looking for senders of a specific message in a specific package? And why is the word âcalls" used? I was proud to have learned from the Pharo book that there are no calls, but only message sends? -- View this message in context: http://forum.world.st/allSendersOf-inPackageNamed-vs-allCallsOn-localToPack… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Monticello question (package renaming)
by Juan Ignacio Vaccarezza May 15, 2012

May 15, 2012

Hi all, Question: Â¿ Is it posible to rename packages in monticello? Meaning by renaming not create a whole new history, but the history contemplates the renaming. Context: I started a project, with a category layout. Then I saved and track the project history using monticello. Then I realized that my package division was wrong (infered from the categories). So I decided to re-think my projects category layout and consecuently renamed the categories. Then new packages shall be created, and my project's history will be gone. Thanks for the help. Regards, Juan

Beginner's questions
by Edouard Klein May 14, 2012

May 14, 2012

Hi all, I tried to build my first user interface with Pharo. I ran into some problems, I have a bunch of questions. These are certainly quite simple to answer for any veteran... If any of you could so kind as to not only answer them but also to tell me where I sould have looked for the answer, this would be awesome. I used Pharo By Example as well as the pharocasts and the occasional google search to find info. My code can be found at : http://ss3.gemstone.com/ss/MakeMeASandwich.html - I build the UI by hand, this is tiresome. Is there a GUI UI builder ? I found Morphic designer (https://www.hpi.uni-potsdam.de/hirschfeld/trac/SqueakCommunityProjects/wiki…) and UIBuilder (http://forum.world.st/CLFramework-UIBuilder-td1302485.html) but it is unclear if any or both are the Right Way (tm) of doing things with Pharo. - As you can see if you do RecipeEditor new open, there is a lot of wasted space. Lists do not expand to take all the vertical space they could. What is the workaround for that ? - I have a list created by : nodeList := ListModel new list: SortedCollection new. put on screen by : builder newListFor: self list: #nodeList selected: #selectedNodeIndex changeSelected: #selectNodeAtIndex: help: 'Liste des Ã©tapes'. and I use : nodeList list at: (nodeList selectionIndex) on the press of a button to get the selected element of a list. I would like this list to allow for multiple selection, and I would like to get the list of selected elements. I tried to fool around with some methods having "multiple" in their name, but to no avail. - The text fields require the user to accept (command-S) the modification before I can get the content with getText. Is there a good way to get the non accepted text ? I tried to to an UI with tk before, and compared to that it has been a breeze with Smalltalk, the way one can write the highest level call and then use the debugger to create methods and variables on the fly is very enjoyable. Thank you in advance, Cheers, Edouard.

Hi everybody We really want to build a "vitrine" showroom of Pharo and we would you to participate. We want to build a web page with all these successes and show it to the world. :) We would like to get from you a three slides document: slide one: a sexy picture and a teaser / who you are. slide two: what is it how cool is it. slide three: what cool pharo techno you used or developed. I did a bad one using DrGeo to give you an idea. So can you please send us these three slides. We would like to present them during the Pharo conf and after put them on the web. Stef and marcus.

[ANN] LRUDictionary
by Norbert Hartl May 11, 2012

May 11, 2012

I like to announce a tiny utility I did for my last project. It is only a single class that basically works like LRUCache internally but on the outside it is more like a dictionary. And it has no factory block. If you don't know LRUCache, it's a fixed size dictionary that sorts its elements by usage in a "Least Recently Used" fashion. Meaning the last used element is put in front and the least used at the end. Elements get discarded at the end if space is full. Apart from #at: that is provided by LRUCache , LRUDictionary implements to following methods at:ifAbsent: at:ifAbsentPut: at:ifPresent: at:put: removeAt: removeKey: removeKey:ifAbsent It is available here MCHttpRepository location: 'http://source.selfish.org/mc/misc' user: '' password: '' Blog article is here http://norbert.hartl.name/blog/lrudictionary/ hope you like it, Norbert

student project: a simple recognizer

Hi guys Here is a topic for somebody that would like to have fun with events. There is a javascript version and it would be cool to have a version for Pharo. http://depts.washington.edu/aimgroup/proj/dollar/ http://www.lifl.fr/~casiez/PJE/OneDollar.pdf It is probably close to Genie but at least the algorithms are clearly defined.

FYI: No JIT on Windows 8 for ARM - luajit - FreeLists
by Sven Van Caekenberghe May 10, 2012

May 10, 2012

That means no official CogVM then ? Both ARM and x86 seems to be problematic. http://www.freelists.org/post/luajit/FYI-No-JIT-on-Windows-8-for-ARM Luckily I am not on Windows ;-) Mac OS X is also moving slowly in the wrong direction of a couple of fronts. Maybe it becomes time to switch to Linux for everything, if only a nicely built 100% supported laptop existedâ¦ Sven

Begin forwarded message: > From: Kim Mens <Kim.Mens(a)uclouvain.be> > Subject: Do you know any candidates for assistant positions in our department > Date: May 10, 2012 10:28:45 AM GMT+02:00 > To: researchers RELEASED <released(a)listes.uclouvain.be> > > Dear all, > > I am urgently looking for possible candidates to fill up some teaching and research assistants in our department. Such an assistant typically has teaching and research duties and gets up to 6 years to obtain a PhD (to be renewed every 2 years). The 6 years is because of the extra teaching load as compared to a normal researchers. Regarding research, they get to choose what professor they want to do research with and negotiate the research topic with him; evidently I'm open to have them under my guidance, but the choice is up to them. Regarding teaching, the teaching charges are distributed equally among the different assistants based on their capacities and interests. The positions are very interesting, and they get a real contract and fair salary (as compared to some other countries). A university level degree of master in computer science or computing science engineering (or something equivalent) is a must. (For foreigners, equivalence of their diploma will need to be verified but that can be done afterwards I think.) Knowledge of French is strongly desired because the bachelor years are still taught in French and we are already quite short on French-speaking researchers to help out with teaching duties in the bachelor years. Knowledge of English is also positive since our Master years are taught in English. Anyway, if you would know anyone, please pass them this information. The deadline is very short since all forms need to be filled in and submitted electronically by May 18, which would mean they need to start working on it right now. A internal selection commission of professors from our department will select the three best candidates from all those who applied. > > More instructions on how to apply can be found here : > http://www.uclouvain.be/11617.html > The candidate needs to fill out the digital form that is available there. If they click on "Listes des postes vacants" they will see the different vacancies currently available for the entire university. The ones related to our department can be found under the faculty "Ecole Polytechnique de Louvain" and more specifically the vacancies with identification numbers 00001941, 00002203, en 00004257. > You will see that 2 of these 3 have a description that is particularly dedicated to computer science. The third one looks more general, but in fact it has been decided recently that it will also go to computer science, but we weren't able to change the description anymore. Interested candidates should thus fill in the form and are strongly advised to apply to each of the 3 positions, even though they can receive only one. (I agree the procedure is a bit absurd, but what did you expect, this is Belgium.) > > Of course you can always contact me for more information or if the procedure is not 100% clear (even though I also had to look all of this up on the official university webpage). > > That's it for now... > > Thanks for your attention to this mail. > > Prof. Kim Mens > UniversitÃ© catholique de Louvain (UCL) > Institute of Information & Communication Technologies, Electronics and Applied Mathematics (ICTEAM) > IngÃ©nierie Informatique (INGI) > Place Sainte Barbe 2, B-1348 Louvain-la-Neuve, Belgique > kim.mens(a)uclouvain.be > > >
