Little challenges for a friday evening

Hi I'm checking how I would implement an isogram checker 'Pharo' isogram >>> true because it contains only single letter. I got a stupid bag drivent implementation but I will do another better and faster. Stef PS: after I will do anagram and pangram to have the family of gram checks (this is for a book).

MOOC TOC cleanup
by Siemen Baader Nov. 12, 2016

Nov. 12, 2016

Hi all, especially Luc, StÃ©phane and Damien, the Pharo MOOC course was fantastic and I use the archived material for reference quite a lot. It is here: https://www.fun-mooc.fr/courses/inria/41010/session01/b116d12e24ec484c98483… But - the English table of contents is in French, and the attached ZIP files need to be downloaded before they can be browsed. It gets quite messy. Would anyone with the required permissions be OK to: - translate the TOC to English - split the ZIP files into separate elements under their respective headlines that can be viewed in the browser or - grant me the permissions to do this work for the community? best, Siemen -- View this message in context: http://forum.world.st/MOOC-TOC-cleanup-tp4921304.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

[ALERT] Pharo by Example version 5 is about to be released
by Dimitris Chloupis Nov. 11, 2016

Nov. 11, 2016

In case someone missed it I will be doing a release for version 5 (pharo version = pbe version) this weekend , since we had Pharo 7 initiated few days ago. Essentially that means that the repo will be tagged for version 5, which means a git commit is associated as a last commit for that version and there will be a frozen release - download for Pharo by Example version 5. After that we move to Pharo By Example version 6 or PBE6 for short The repo wont change otherwise and the process of submitting commits, pull requests and issues remains the same. If you have found a flaw of any sort in the documentation , please open an issue in the github issue tracker that can be found here https://github.com/SquareBracketAssociates/UpdatedPharoByExample/issues I will try to fix any problem reported but if I cannot , the fix will have to move to version 6 As always thanks to all people contributing into the impossible .... making Pharo more amazing If you want to contribute feel free to do so with a pull request. Does not matter if you are beginner because even minor corrections like correcting mistakes in the grammar or content of the text, updated pictures, or just a few lines of extra info are more than enough and more than welcomed. Many Pharo beginners have already done so . -Salute to fellow Guardians of The Light

Re: [Pharo-users] Image freezes on Linux if it was previously saved on Windows
by Nicolai Hess Nov. 10, 2016

Nov. 10, 2016

Hm, I don't know what exactly happens. It seems this behavior started with Pharo 50574. Since that image version, the UUIDGenerator will be reset on startup. Maybe the initialization of the uuidgenerator (or the random seed) will access the filesystem and at this step the file system initialization traps into an infinit loop. What I don't understand is, why this only happens when the image was saved on a windows platform and reopened on a unix platform. Maybe, saving the image (or the shutDownList) does not fully cleanup the platform settings.

Pier3 with latest Pillar?
by Peter H. Meadows Nov. 10, 2016

Nov. 10, 2016

What needs to be done to get Pier3 to use the latest Pillar code? I think I've got it partly working with a few small changes. (an isEmbedded method was missing, and PRFigure needed some changes). Relevant slack discussion below. Peter Meadows [6:45 AM] I was trying to run Pier3 Max Leske [6:45 AM] I assume that didnât work as you had expected :slightly_smiling_face: Peter Meadows [6:45 AM] It half works [6:46] I can read pier pages but not edit them Max Leske [6:47 AM] Do you see a debugger? Peter Meadows [6:47 AM] when? Max Leske [6:48 AM] When you try to edit a page. Or does it just silently refuse to work? Peter Meadows [6:49 AM] it's silent Max Leske [6:49 AM] Hm. [6:50] Did you load Pier3 through the catalog as well? Peter Meadows [6:51 AM] but i had to change some things, and i might not have done it in the best way. Because the newest pillar seems to make PRFigures when it should used to make PRLinks .. or something. I don't really understand it. [6:52] no. custom [6:52] the catalog uses an old version of pillar [6:52] i think [6:55] I had to change PRDocumentParser to PRPillarParser Peter Meadows [7:00 AM] and why does Magritte need seaside? I thought they made it completely independent? Max Leske [7:02 AM] It doesnât. As far as I can tell, the problem is somewhere between Pier and Seaside. [7:03] When I try to load Pier I get exactly the same error as you but I can load Seaside3 by itself without problems. This may possibly be a Metacello bug. [7:05] Concerning pillar, you probably best ask Cyril Ferlicot. And for trouble with Seaside / Pier itâs best to ask on the seaside mailing list Peter Meadows [7:08 AM] ahh. well that might explain why it has been confusing/confounding me! Peter Meadows [7:20 AM] does Metacello not have a very verbose setting? Stephan Eggermont [7:48 AM] @anteater: Pillar forked from Pier and did not maintain compatibility. I have not updated configurations for Pharo 6. Magritte and Seaside are independent. Load the right metacello group to get a combination. Stephan Eggermont [7:54 AM] @anteater: just load Pier3 from the catalog and check the package cache to see if what is loaded is what you expect. Without pharo6 tags, very old stuff gets loaded Peter Meadows [7:56 AM] Yes, but I wanted my Pier to use the latest pillar code. Surely that was always the plan? It hasn't changed dramatically i think? [7:57] If it was actually a fork they would/should have changed the name! Stephan Eggermont [12:43 PM] @anteater it is definitely a fork with lots of breaking changes. No compatibility [12:46] Pillar broke compatibility on purpose and had zero interest in keeping things working [12:50] ConfigurationOfMagritte3 load loads a default group, which is often not what you want Cyril Ferlicot [12:54 PM] Is there a lot to change in Pillar/Pier to keep compatibility? Pierce Ng [2:01 PM] @cyrilferlicot the Pillar part of Pier has been taken out of Pier and made standalone, so Pier has to be updated to use Pillar. i looked at this a while back so maybe Pier has been kept updated. Stephan Eggermont [2:49 PM] @cyrilferlicot: flatten traits. Pier is cross-dialect. The other things were easy, just breaking the build once a month Cyril Ferlicot [2:51 PM] Maybe when Pillar will move to github we will be able to do a Pharo branch with trait and a flattened branch for cross dialects. [2:52] I think I broke a lot of compatibility during my internship but that was not because I did not wanted to keep compatibility but more because I did not knew the relation between Pillar and Pier. That was the first time I contributed to a real project :slightly_smiling_face: Stephan Eggermont [2:52 PM] Should not be difficult. It just asks for some attention to downstream consequences Dimitris Chloupis [2:53 PM] you are not the only one [2:54] even in the PBE we had half the files in pier extension and half with pillar extension Stephan Eggermont [3:06 PM] @cyrilferlicot: I didn't assume you intended to break things. Pierce Ng [4:07 PM] my blog has switched to pillar. before it was shelling out to the markdown executable called discount. so now the blog has one fewer dependency. thank you for the standalone pillar.

Streaming MP3 playlists

Hey, All.. Was wondering what the state of streaming audio was.Â I am building a radio API for use in a mobile player using Teapot, but I thought it might be cool to build and actual player using spec and pharo. Any suggestions on where to look for something like this for pharo 5?
