Fast Table: How to solve dependency on FTTreeDataSource
by Offray Vladimir Luna CÃ¡rdenas Nov. 8, 2015

Nov. 8, 2015

Hi, I'm making some data storage in SQLite, because of its self-contained nature and because it let me focus on visualization by delegating some query and storage matters to the little database. But for some moments I have the data in an ordered collection, which starts to lag for 10.000 items. I would like to explore fast table as a way to storage my temporal objects before putting them in the database, but when I'm trying to install Glamour-FastTable there is a warning message about a dependency on FTTreeDataSource. I tried running the following code: ===== Gofer it smalltalkhubUser: 'estebanlm' project: 'FastTable'; package: 'FTTreeDataSource'; load. ===== but is not working. How can I solve that dependency? Thanks, Offray Ps: See some of you soon in Smalltalks Argentina. I'm already on Buenos Aires. Is a really beautiful city and having the opportunity to reconnect face to face with smalltalkers will be great after my last Squeak Fest talk in 2007.

Code critic is malfunctioning in my image as i mention in pharo-dev thread, I want to disable it but I could not find it in the Settings because my problems with it have been getting much worse as it throws MNUs even for mouse clicks. How may I do this ?

Smalltalk Meetup in ZÃ¼rich: Nov 10, 2015
by Joachim Tuchel Nov. 8, 2015

Nov. 8, 2015

Dear Smalltalk fans in the ZÃ¼rich area, if you happen to have a free slot in your calendars for November 10th, 2015 (I guess 19:30 will be a good time to start), I have something for you: We would like to get together with Smalltalkers of all flavors to chat about the latest news, tools and projects at a restaurant near Bahnhof HardbrÃ¼cke, like we did several times in 2014. I think it's time to catch up and I know Peter, Philippe and Michal feel the same. So please send me a note and let me know if you'd like to join us for an evening of Smalltalk... I'll reserve a table and let you know exactly where we meet. If you are not in the ZÃ¼rich area but don't mind travelling to meet us, feel free to come! Hope to see you soon in ZÃ¼rich! Joachim

Trying to understand OSProcess on MacOS Yosemite
by Dimitris Chloupis Nov. 7, 2015

Nov. 7, 2015

So I try to understand how OSProcess work exactly to find why filetree seems not able to use it and generating the error I already reported earlier. Using something simple like OSProcess command:'pwd' works great , I have the terminal open and I can see the correct return value of the command in my terminal but for some reason I can find no such info when I inspect the above example. So how exactly OSProcess returns the output of the terminal ? Is there an instance variable of some sort ? Because I tried to inspect it deeply and I found nothing . Can you help me understand how OSProcess work ? Because If I do understand it then I can find what the problem is .

Hello I have attended a formation with Stephane Ducass in LomÃ©-Togo. And I am about to start a new project: an immobilier management application built in pharo with a pgsql database for a company here. So I am looking for some Documentation on Garage. For the basic purposes: -connection -queries -etc Thank you

How do you get a password reset for a SmalltalkHub account? (I'm convinced the EuanM who has an account is me, but I cannot manage to log in)

[ANN] QuickAccess for Pharo 5
by Torsten Bergmann Nov. 5, 2015

Nov. 5, 2015

Hi, I quickly wrote yet another small tool to work faster with Pharo. I call it "QuickAccess" - it's some kind of "ScriptManager 2.0" allowing you to quickly access actions (defined as code scripts) via Spotter, Menu, Button, etc. You can load it from Spotter/Catalog in Pharo 5.0 beta. The following video demonstrates how to use it: http://youtu.be/j-dTp6i_P3s The defined structure including the scripts can be exported to a file and send around. So far it is "complete" for my own requirements - if you feel something is missing you can contribute and help moving it forward. The repo is at http://www.smalltalkhub.com/#!/~TorstenBergmann/QuickAccess Contact me with your STHub account if you need access. The tool has some similarities with Playground/script cache, but GT tools lack the category structuring for scripts that you find in QuickAccess. It might be an inspiration for a future unified script management solution in Playground. Have fun! Bye T.

[ANN] Working with Pharo on the Raspberry Pi
by Torsten Bergmann Nov. 4, 2015

Nov. 4, 2015

For me this combination worked and was faster than the one that I described in the article: => Image https://ci.inria.fr/pharo/job/Pharo-5.0-spur32/lastSuccessfulBuild/artifact… => VM http://www.mirandabanda.org/files/Cog/VM/VM.r3427/cogspurlinuxhtARM-15.33.3… So I happily run Pharo 5 on the Pi now. Bye Torsten
