I too struggle with what appears to be duplication of efforts, but I'm reminded of two related themes which Alan Kay talks about a lot: - evolution is closer to a random walk with a slight bias than a straight line - in biology, what often appears in human illustration/simulation as components interacting in lock-step as if on a track is actually fortuitous, made possible by the tremendous speed and energy of everything going on in the cell So, as you discovered, and I need to be repeatedly reminded of, there is no perfect world where the stars align and each piece moves with speed and precision into its predestined place in the whole. There is only a sloppy, often frustrating, two-steps-forward-one-step-back frenzy where what comes out on the other side is hopefully better than what we started with. Said more simply: "this is what winning looks like" ----- Cheers, Sean -- View this message in context: http://forum.world.st/Beacon-and-SystemLogger-united-tp4773973p4773975.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Re: [Pharo-dev] Looking for suggestions for extended Pharo/Smalltalk intro demo

Oscar have a look at my DSL chapter (in PFTE) https://ci.inria.fr/pharo-contribution/job/PharoForTheEnterprise/724/artifa… and video http://stephane.ducasse.free.fr/Videos/2013-04-20-Dice-v3.mov it shows tests class extensions loops DSL I use it for my lectures and it was fun to do live. In Lviv the other students explained to my black jack on the fly and I developed test first. But I do not remember the game :) You can build it live and after you have the exercises that they can do. Look into the git repo because you get the exercises in skeleton mode. So they have to build step by step the exercises On 20/8/14 16:07, Oscar Nierstrasz (gmail) wrote: > Hi Folks, > > I will be teaching a Software Design and Evolution course this Fall in which we use a lot of Smalltalk.

Beacon and SystemLogger united

by stepharo

Hi what I like with conferences like ESUG is that we can meet other people. We got some great discussions with Doru and Norbert about logging. And we will unite the two frameworks into a a variation of Beacon. Thinking about it, I clearly overreacted when Doru announced Beacon and I'm clear with it. I'm not an easy guy from that perspective but I have no problem to try to understand and recognize other ideas. I think that this is partly the effect of mail communication. Retrospectively I was so into wanted to remove all these strings from everywhere that I received Beacon (which at the end was trying to help defining a cool logger) as a sign that I lost my energy on building SystemLogger. Now I think that if I would not have built SystemLogger, we would not have got Beacon and our discussions would have been way poorer. So we will start to migrate some of the SystemLogger code to Beacon, rename some Beacon class, and write a new documentation and integrate all that into Pharo. Stef

Re: [Pharo-dev] Transcript class allInstances does not list all instances

by Camille Teruel

Hi Oscar, It's because Transcript is only one instance of ThreadSafeTranscript. 'Transcript open' doesn't create a new instance but opens a new window on that instance.

Transcript class allInstances does not list all instances

by Oscar Nierstrasz (gmail)

In the latest Pharo 3 for Mac: Transcript open. Transcript open. Transcript class allInstances inspect only shows one instance, not two. Why? Oscar

Looking for suggestions for extended Pharo/Smalltalk intro demo

by Oscar Nierstrasz (gmail)

Hi Folks, I will be teaching a Software Design and Evolution course this Fall in which we use a lot of Smalltalk. For the introduction to Smalltalk lecture I wanted to give an extended demo with some slides in between rather than mainly showing slideware. Does anyone have a good recommendation for an application to build with the students while showing off most of the important features of the language and the environment? Ideally something you have used before in precisely this way. Some things I have used in the past: - Post Office example (small and boring) - Snakes and Ladders (a bit too big) Thanks for suggestions. Oscar

Re: [Pharo-dev] Initial versions for OSWindow and Woden

by Ronie Salgado

> > Ah, so "not on Mac yet" only applied to OSWindow? What would it take to > have > that working? Maybe I can help... OSWindow to fully work requires a custom VM. For Mac, I actually already tried using one of Alex Mac. It worked, but when I tried an older version of Woden and OSWindow it crashed. With Igor and Esteban we will take a better look on this. Okay, I see all Woden examples work on Mac except WDTerrainExample and > WDPhysicsExample WDTerrainExample uses OpenCL with OpenGL interoperability, whose support I have not added yet to Mac. The API for creating an OpenCL context with OpenGL interoperability is a bit platform specific. The WDPhysicsExample uses Bullet. The Bullet bindings are quite tricky to build/load in comparison to a typical Pharo project. It requires my modified version of Swig. This version of Swig can generate NativeBoost from a C/C++ header. It is available in: https://github.com/ronsaldo/swig The Bullet bindings and scripts for automatically building for Linux are here: https://github.com/ronsaldo/bullet-pharo I need to provide a more pharoish way to build Bullet and the bindings.
