adding credentials to a repo via a playground script
by Peter UhnÃ¡k March 8, 2016

March 8, 2016

Hi, is it possible to add credentials to an existing repo via a script? I've tried something like ~~~~~~~~~~~~~~~~~~~~~~~~~ |repo| repo := MCSmalltalkhubRepository allInstances detect: [ :each | each location includesSubstring: 'Pharo50Inbox' ]. repo user: 'peteruhnak'; password: '******' ~~~~~~~~~~~~~~~~~~~~~~~~~~ but it has no effect. Thanks, Peter

NativeBoost replacement?
by HernÃ¡n Morales Durand March 7, 2016

March 7, 2016

Hi guys, I am porting packages which uses NativeBoost in Pharo <= 4 to Pharo 5 (update: #50628). Since NB is not supported anymore I would like to know which is the replacement of such library. I found FFI is loadable in Pharo 5, but methods like #getForegroundWindow are missing. Even worst, when I try to browse a method like #shellExecute:lpOperation:lpFile:lpPrameters:lpDirectory:nShowCmd: with any tool (Nautilus, Finder, etc) I get a MessageNotUnderstood: RubShoutStylerDecorator>>disableDrawingWhile: What's your recommendation? Cheers, HernÃ¡n

Hello, I noted, twice since yesterday, Nautilus can have code panel contents unsynchronized between two instances of itself: - two nautilus windows on the same class - edit a method in window 1 - look at the modified method on window 2, it is the old code Hilaire -- Dr. Geo http://drgeo.eu

Lost class migrating from 3.0 to 4.0
by Hilaire March 7, 2016

March 7, 2016

I am migrating a web application from 3.0 to 4.0. I noted one class can't get load! It is however present in the Squeaksource repo. The class is a WAComponent, it is the entry point of the application with all the initializations. All the libraries dependencies are satisfied. I don't see reason why the class can't be load, and there is no such warning. Trying to load by hand this sole class does not work either. Did any of you meet such problem with Pharo 4.0 Hilaire -- Dr. Geo http://drgeo.eu

Hackathon question (kind of urgent): Adding labels to a treemap
by Offray Vladimir Luna CÃ¡rdenas March 6, 2016

March 6, 2016

Hi, We're in our local Open Data Day hackathon, creating a treemap to visualize public spending. We have cleaned the dataset and made some queries to zoom into the info we're interested in. So far, so good, but now we would like to change the labels on a treemap. So consider this code: ============= | b labels | b := RTTreeMapBuilder new. labels := #('uno' 'dos' 'tres' 'cuatro' 'cinco'). b shape fillColor: Color random. b from: (1 to: 5) using: [#()]. b weight: [:n | n]. b build. ^ b view. ============= How can I add the labels from labels to each of shapes of b? Thanks, Offray

PharoLauncher eventual slowdown
by Peter UhnÃ¡k March 6, 2016

March 6, 2016

Hi, I've been using Pharo Launcher for quite a while and problem that I am constantly encountering is that launching of it becomes slower and slower. Up until now I've solved it by writing a bash script that downloads the launcher fresh and reconfigures it. And then I've executed the script about once a week. But I am little bit fed-up by itâ¦ is this a common behavior? Or is it constrained to my machine? For example, if I execute the following (so I can time it) time /opt/pharo-vm/cog/pharo --nodisplay --textenc UTF-8 /opt/pharo-launcher/PharoLauncher.image eval '1+1' (also I have right now about ~27 images in the Launcher) fresh download (yesterday): ~0.49s today: 0.91s (almost double) and in a week it will be be maybe 10 seconds. I can just setup cronjob that resets pharo launcher every day, but a systemic solution would be better. Thanks, Peter

Suggestion: ChronosManager Should Enable Sound in Settings

It was a bit surprising when I checked the timer and saw that the alarm had silently fired quite a while ago as I worked on unaware! ----- Cheers, Sean -- View this message in context: http://forum.world.st/Suggestion-ChronosManager-Should-Enable-Sound-in-Sett… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Call about Numerical Methods in Pharo :)
by stepharo March 5, 2016

March 5, 2016

Hi guys I met Didier Besset and we had a great hacking session and discussions with Serge Stinckwich. Didier would like to help Pharo and the numerical part of it. ***Big thanks*** Didier. We would like to do several things: - Work on "Hows to" The numerical methods in Pharo is good but the gap between us and the math is too large :) so the idea is to have a series of "how to ..." - histomgram (simple, based on distribution) - Improve the SciPharo/NumPha (previously SciSmalltalk) library This morning we started to implement a ComponentPrincipalDecomposition by combining two of the objects available in SciPharo. Then we started to enhance the distributions to make sure that we can plug other distribution for having controlled random number. - Do a public call to know what is missing for you: this is this mail :) Didier would like to work on concrete cases. I love that attitude So tell us :) Hernan ?? Alex: ?? pvalue? better distribution? Vincent: covariance? CPA? Philippe: times series Serge R frames? Sami: Better random number and various distributions? - Organise a two day lectures with practices on concrete case in September with a recording session. Either at IRD Bondy or Lille. - Make sure that the Numerical Method book will get on lulu :) with a better cover and title :) Stef
