Thanks mariano. It was cool and I like the hands-on because we are not just taught but we participate and learn. On Mar 11, 2011, at 10:44 PM, Mariano Martinez Peck wrote: > Hi all.

[Pharo-project] the glamorous toolkit project

by Tudor Girba

Hi, I would like to promote the idea of projects in Pharo. The concept is simple: we should build new infrastructures that go beyond small fixes and that require the concerted work of multiple people over a longer period of time. A project has a clear goal, and is led by someone. That someone is not necessarily the one that writes all the code (like we might tend to do it), but simply one that ensures that the project advances, that the different contributions are integrated, and that things are not left at 90%. I would like to announce the Glamorous Tool project. The goal of this project is to provide a new set of tools for developing with Pharo. It is to be developed on top of Glamour, and it should address at least the followings: - Coder (ex-System Browser) - Debugger - Inspector - Playground (ex-Workspace - it's not called Workspace anymore because I would like to encourage people not to "work" there) - Chaser (senders, implementors and references) The project spans several topics. For example: - Glamour support - Morphic enhancements: --- Proper TextMorph with keybindings and context sensitiveness --- Collapsable Panes --- Scalable tabs --- Parallel rendering - Suitable models --- RPackage --- Code introspection --- Debugger model - Testing --- Because these tools are so critical, they should be robust --- OB is a good example for the testing part - Usability --- Principle: Spawning a window might be easy, but it is not effective --- Principle: Uniformity --- Principle: Less concepts are better than many - Graphic design of skins and icons - Weak announcements - Performance I will lead it, and you are welcome to participate. The today sprint is a good occasion to take a look. The current code can be found at: Gofer new squeaksource: 'glamoroust'; package: 'ConfigurationOfGlamoroust'; load. (Smalltalk at: #ConfigurationOfGlamoroust) perform: #loadDefault. Cheers, Doru -- www.tudorgirba.com "Sometimes the best solution is not the best solution."

[Pharo-project] THANKS a lot for the awesome Deep Smalltalk School

by Mariano Martinez Peck

Hi all. I am doing quite an effort to have the laptop opened and type some words....heehhehe after a whole vm hacking week I promise I cannot do more.. I wanted to thanks everybody for the unbelievable Deep Smalltalk School that we had. I really thanks everybody involved: organizers, INRIA, ESUG, EDM and other sponsors, you, etc. Even if some people don't notice, I know that some of you spend a lot of time and energy (instead of using such yout time for something else). I promise it was more than worth it. The school was a success. People come over the world: Canada, USA, Argentina, Norway, Germany, Belgium, Spain, France, etc. We were around 45 persons. Even if I am a VM newbie, I like low level stuff. Sometimes when you go to ESUG, Smalltalks or any other conference, you can see one or two 30-minutes-talks about VM, compilers, etc. But do you image what is a whole week from 9:00 to 18:00 talking about VM, Compiler, Parser, Networking, optimizations, etc ??? It is really cool!!! If there is something like this again in the future, please, consider coming, you won't regret. The best thing is that since we have a lot of hours, we can have not only the theoretical lessons, but also the hands on. So, we were able to: compile CogVM from scratch, implement a Twitter like app, create some petit parsers, optimize some real code, create a minimal Hazelnut image, create a VM plugin, etc.... So, once again, thanks a lot to everybody involved. Cheers Mariano

Re: [Pharo-project] Issue 3806 in pharo: Duration>>hours is broken

by John Toohey

I just finished debugging a production server that had a similar issue. Basically I need to select from a collection all events that were opening in the next 24 hours. I have code like :- hours := (each eventOpenTime - timeNow) hours. hours between: 0 and: 24. I thought this was working before, but debugging the server today, I saw that every event was between 0:23. The #hours message only returned the hours portion of a time, not the amount of hours. I had to change the code to :- hours := (((each eventOpenTIme - timeNow) asSeconds) / 60 / 60) asInteger. Anyhow, I guess the name was misleading to me, as there is no #asHours message, but these is #asSeconds, and an #hours and #minutes, but no #seconds.

Comment #5 on issue 3806 by cesar.ra...(a)gmail.com: Duration>>hours is broken http://code.google.com/p/pharo/issues/detail?id=3806 While I can second Sebastians' complains based in intuitivity, I got confused with the redaction of the ANSI standard, which I have only a 1.9 Draft in PDF form: 5.8.2.11 Message: hours Synopsis Answer the number of complete hours in the receiver. Definition: <Duration> Answer an <integer> between -23 and 23 inclusive that represents the number of complete hours in the receiver, after the number of complete days has been removed. If the receiver is less than <Duration factory> #zero then the result will be less than or equal to 0. Return Values <integer> unspecified Errors None This text seems to support the implementation of the method which is attempting to give the number of fractional part of the duration. It does not seem to be a conversion protocol, but rather an equivalent to the mod operation for hours, or seconds or whatever. Test this: (DateAndTime now - DateAndTime today) hours. In my image, at the time I tested it gave a correct "16".
