I use it mainly for teaching at the university: - Free (no cost) and Free (open source) - The easy setup allows my beginner students to focus on OOP topics - Several integrated tools: programming environment + test framework + coverage tool + source control tool. All other popular langages (java, ruby, python, etc, etc) requires several downloads (and setups) to do the same - It is portable between different OS and the features we use work exactly the same way everywhere Saludos!

Package browser

by Vincent Lesbros

I did not find how to get the OB Package Browser. My Browser displays categories, but not packages. in the top right menu of the Browser, item "Choose new default browser" I have only two choices : Browser OBSystemBrowserAdaptor In the book PBE1-2009-10-28.pdf "Pharo by Example " it is showned a OB Package Browser ... But how can I get it ? (I did read FAQ 5, p. 318.).

Memory

by Vincent Lesbros

Hi What is the maximum size supported for Arrays in Pharo ? I have to manipulate a lot of Pixmaps and large sound files. for example : 30 minutes of 4 channel sounds in 32bit at 48000 Hz = 30 * 60 * 48000 * 4 * 4 = 1 382 400 000 bytes. 1 picture 3648 * 2736 pixels 24bits/pixel = 29 942 784 bytes. How many pictures can I load in memory ? My physical memory is 8 GB. VL.

Sounds / Silence

by Vincent Lesbros

Hi, I am new to Pharo, I try to get a sound from the SoundPlayer. I use : Pharo-1.3-13315-OneClick.app I did : BaseSoundSystem soundEnabled: true I create an instance of AbstractSound, from the beep example, or an instance ofPluckedSound... whatever. And, when I send the message play, the primitive to play the sound fails. *primSoundStartBufferSize: bufferSize rate: samplesPerSecond stereo: stereoFlag* "Start double-buffered sound output with the given buffer size and sampling rate. This version has been superceded by primitive 171 (primSoundStartBufferSize:rate:stereo:semaIndex:)." "ar 12/5/1998 Turn off the sound if not supported" <primitive: 'primitiveSoundStart' module: 'SoundPlugin'> *SoundSupported := false.* La primitive Ã©choue et le flag *SoundSupported est remis Ã false.* * * *My environnemt is windows 7 64bits,* *I do have a sound card !! * * * * * *Where is the good plugin and how should I activate it ?* * * *thanks,* * * *VL.* * * * *

The core is simple. Easy prototyping. It's a place to learn. Nice community. So this is my platform of choice to try things, prototype, create my tools. The Plastic metaphor seems correct. But keep in mind we have to choose programming systems because they solve problems. - what kind(s) of problems Pharo will solve best ? - what kind(s) of users Pharo want to have ? It looks like Pharo has a real place on tablets (Hilaire proves it with DrGeo). Now I'm not sure about "essence of agile". TDD in Pharo does not seem so popular - there's more and more tests, but feedback on testing practices is low. I would like to see timeboxed iterations with goals for Pharo development process - that would be agile and provide a rhythm.

Hello StÃ©phane i use Pharo in combination with Seaside because it is a really good platform for end user applications. (although i am currently not so active on this, because of other IT tasks) This went so far that I didn't even use the internal GUI for the apps user panels. instead everything via internet browser.. There should be more Internet Service Providers which offer (faster) Pharo/Seaside environments. As of today, most of ISPs don't even know what Seaside or Smalltalk is. (in-system intranet apps are mostly not a problem, fast enough) If this providing problem is solved than i see a great future for Smalltalk web based apps. because almost everything is in the same smalltalk environment, easy to program (well, once you learned Smalltalk) debug, and maintain. Cool. I found no other programming language that is so pleasant to work with as Smalltalk. and i like the Pharo development environment. You might recall the discussions i also was involved in about downward compatibility etc.. we had discussions about the impact of changes. Therefore: I'd prefer to see the Pharo environment (metaphorically) rather like a sun/star: solid core and more and more flexible going outwards.. in principle: the deeper (inner) one changes things the harder it becomes for the outer layer objects (apps) --- I think Smalltalk will evolve much further through the years Dreaming of a Smalltalk (or Self?) environment with no external data (like databases) except import export (oops, Collection classes need a drastic overhaul then :o) Everything integrated concept: VLI (Very Large Image. Terabytes..) Running IN a mainframe. Like a living entity. With the computers still rapidly improving this becomes very feasible. to backup? simply copy push down the whole image :o) Kind Regards Thanks all for Pharo.

I was introduced to Smalltalk by someone describing it as "you install it and then you change the Smalltalk installation until it has the functionality you wish." What i love most about Pharo is the evolving documentation ("A comment per day", Pharocasts, Second Volume of PBE, blog of Mariano Martinez Peck)! "More class comments" (more method comments?!) should be the first point in the ActionsInPharoOneDotFour document :) I cannot resist to add this Andy Warhol quote: "I love Los Angeles.

* Advertising is about target audience.. * One needs to advertise only if there no definitive uniqueness for the target audience I would prefer if the message is like the Apple focus: * Pharo will be the best enterprise platform in 2 years: State the technical roadmap in say 6 month release cycles. * Identify and project credible projects/ products using frameworks that are really capable of being viral. ( Frozen really stable, the best kernel that is not materially going to shake or change, Other goals, frameworks are hard fixed , clear roadmap, We already are beginning to have a more vibrant research activity that is adjunct and important but not the major factor in enterprise decisions. ). To achieve that message it should be implicitly felt not explicitly stated by any serious quick research: Let the enterprise folks come in , try , feel and agree it is the best, we do not/ should not need to really market it. We need to market a product which either really lacks differentiation, or is a pure consumer product. * The Pharo website be continually improved to reflect that clean, minimal but complete professionalism. * Pharo Consortium may stoke any serious effort by any individual or small group for startups.. You never know which startup later becomes the Google, Facebook of tomorrow.. to achieve in one stroke all that you need to. * Need to have Martin Fowler's , Kent Beck's of the world using Pharo as the base of their Industrial Research: not Ruby or Java .. if possible.. identify how n why.. typically it is this group that has made the difference of adoption by seeding the argument * Can we synergize with VW: Pharo should be the perfect vehicle for any enterprise to start out with and later optionally move to running on top of VW like the Weblogic/ Websphere capabilities over a core free Java. They can stay on with Pharo like 3D ICC supports for Teleplace with squeak.
