[ANN] Launching Pharo on Ubuntu

by Damien Cassou

For Ubuntu users who are using my PPA (https://launchpad.net/~pharo/+archive/stable/) you can now launch Pharo from either the Ubuntu Dashboard or the terminal (just type 'pharo'). In both cases, you will see the Pharo Launcher from which you can create new images from templates on the web and launch existing images. http://www.smalltalkhub.com/#!/~Pharo/PharoLauncher No need for manual download of zip files, unpacking, and directory management. The launcher does everything for you. Have fun -- Damien Cassou http://damiencassou.seasidehosting.st "Success is the ability to go from one failure to another without losing enthusiasm."

11635: Race condition in SequenceableCollection>>shuffle

by Max Leske

Sven suggested posting this on the list for discussion, so here you go: > Maybe this should be discussed on the list, your are going to break API. > > Note that there is also #sort and #sorted with similar copy behavior. > > Also, I am not sure that basic operations should use mutexes to protect themselves by default: there is a cost when you are a single threaded user. Even in Java there are synchronized and non-synchronized versions of collections. IMHO, the protection should happen in your app, and basic collections do not have to be thread safe. > > Sven > >> #shuffle does not use Collection>>mutexForPicking as other users of #randomForPicking demonstrate.

This is very confusing. >> >> I propose a fix where #shuffled and #shuffledBy: are renamed to #copyShuffle and #copyShuffledBy: and moved to the "copying" protocol. #shuffle and #copyShuffle will use the mutex to prevent race conditions.

Re: [Pharo-dev] Extending HelpTopic

by Esteban Lorenzano

please, do not take it as a disincentive to collaborate, this should be quite the opposite :) I was trying to ask for some patience because when you join into a collaborative community, obviously the times spent on "the process" will be different than if you work alone. The gain is obvious, but we often lose from mind the price to pay (you do not control all the stages of the process). So, if you submit something, it will be some time to get the feedback (time to people to notice your change, to see it, etc.). Also, I was not talking about Marcus, Stef or me... since we are not the reviewers (that's also a responsibility of everybody in the community): we are just the integrators. So please, continue committing changes to the process... the review will come :) btw... one thing that I usually do when working: I commit slices even if they are not ready. Then I continue submitting slices until work is done... then I move the fix to "review needed". That way you can work in big changes and also be preparing a SLICE for the right moment. cheers, Esteban On Sep 23, 2013, at 11:19 AM, kilon <thekilon(a)yahoo.co.uk> wrote: > EstebanLM wrote >> also, putting your code in "review needed" would help to reviewers to >> notice that you submitted something :) >> >> On Sep 23, 2013, at 11:07 AM, Esteban Lorenzano < > >> estebanlm@ > >> > wrote: >> >>> you submitted yesterday... a sunday... and we have a not so big >>> community, and all of us has a lot of tasks and things to do. >>> you should be a bit more patient :) >>> >>> Esteban >>> >>> On Sep 23, 2013, at 10:56 AM, kilon < > >> thekilon@.co > >> > wrote: >>> >>>> I take it from the silence , there is no interest in my code :D >>>> >>>> That's fine I will create my own HelpTopic class and keep it independent >>>> from pharo internal libs so I dont have to bother people with slices >>>> they >>>> don't deem important :) Makes my life easier too ;) >>>> >>>> >>>> >>>> -- >>>> View this message in context: >>>> http://forum.world.st/Extending-HelpTopic-tp4709645p4709730.html >>>> Sent from the Pharo Smalltalk Developers mailing list archive at >>>> Nabble.com. >>>> >>> > > No problemo this is why I submitted this slice to see how the overall > process work and gain some experience so when the time comes to fix a pharo > bug I can do it properly. > > yeah this is why I decided to keep code bases separate.

And you think this affects pharo and smalltalk questions ? because as far I have seen, there is nothing to complain about. Even one of my questions about nbopengl whether i should use it could easily be closed and it did not. Maybe its bad with other languages , but so far it looks fine to me, am I missing something here ? Could you link pharo and smalltalk examples that indicate the problem ?

I find people ... hilarious. That's my disappointment speaking. It was a great idea. I'm an early stackoverflow user with 10K+ reputation. The first year it was pretty good, but I've seen it rapidly detoriate to the level where looking at random new questions doesn't make sense anymore. The result of that is that there is no longer the cross-pollination that made stackoverflow an interesting site. Stephan

Write Undefined in a Workspace and inspect it; if you have undefined classes referenced, they will be listed there and you have a contextual menu entry for searching where they are used. To see that you have progressed (i.e., removed some undefined or updated your configuration), select and do it a workspace: Smalltalk cleanOutUndeclared And inspect again Undefined.
