If you want to try: (ConfigurationOfOmniBrowser project version: '1.1-baseline') load works in pharo 1.1 (provided you have ConfigurationOfOmniBrowser from Lukas's source, which should be the case). Love it already!

Creating ArrayedCollections
by Sean P. DeNigris Sept. 27, 2010

Sept. 27, 2010

I'm subclassing ArrayedCollection while coding the examples from A Mentoring Course in Smalltalk, but I can't figure out how to create one! ClassBasedCharacterArray is a subclass of ArrayedCollection ClassBasedCharacterArray newFrom: 'a string' -> error: ClassBasedCharacterArray cannot have variable sized instances. Huh? Behavior class>>new: calls Behavior class>>basicNew: which calls Behavior class>>isVariable which returns false. How does string get around this to create instances? I DebugIt-ed 'a string', but couldn't follow it in the debugger for some reason. Thanks.

Which of course would be tricky as there is no block for the parameter... it has been optimized away. The solution to all these things is of course late-binding optimization to the point when all information is available.

Support for SCIM on Linux
by DavidWilson Sept. 26, 2010

Sept. 26, 2010

Hi I'm trying to input Tibetan (i.e. Unicode) characters using the SCIM input method (Wylie tibetan aka EWTS) on Ubuntu (10.4). (N.B. That's not the same as a different keyboard layout!) SCIM works ok for OpenOffice and even for gedit, but not in Pharo, ie it is installed correctly and working. I suspect it's because Pharo consumes the keyboard input directly, and doesn't let SCIM do its stuff (essentially aggregating keystrokes before sending the unicode on to application). It would be nice to hear from a) anyone who's got this to work in Pharo, or b) someone who can confirm what I suspect. The equivalent works fine on Mac!

Hello and Mac OS X question
by Marc Hanisch Sept. 24, 2010

Sept. 24, 2010

Hello List, my name is Marc, I'm a programmer from Germany developing B2B PHP-Web applications as my profession. In my spare time I try to discover Smalltalk and I'm very impressed and somewhat overstrained about the big range of different Smalltalk distributions, tools and possibilities. So I decided to look at Pharo by reading Pharo By Example. I'm using Pharo on my Ubuntu-Box and on my MacBook, too. Now I'm wondering, how to load an previously saved image on Mac OS X? On Linux I copy & change the ./pharo.sh file. Is there any best practice to open such an image? There is no facility to open an image from within the Pharo-IDE. Sorry for that newbee question, I'm somewhat confused ;-) Thank you very much and best regards, Marc -- http://twitter.com/dubst3pp4 http://dubst3pp4.wordpress.com

Fwd: [Esug-list] Position Vacancy: New Mexico Highlands University
by Mariano Martinez Peck Sept. 24, 2010

Sept. 24, 2010

---------- Forwarded message ---------- From: StÃ©phane Ducasse <stephane.ducasse(a)inria.fr> Date: Fri, Sep 24, 2010 at 5:18 PM Subject: [Esug-list] Position Vacancy: New Mexico Highlands University To: ESUG Mailing list <esug-list(a)lists.esug.org> Position Vacancy (Subject to funding and program approval) New Mexico Highlands University plans to offer both an undergraduate (BS) and graduate (MS) degree in Software-driven Systems Design. The undergraduate program is in place and State of New Mexico approval of the graduate program is in its final stages. Final approval during the legislative session in February 2011 is hoped for but is not guaranteed. If approval is forthcoming the position will be open as early as summer term (May 2011) and definitely by fall term (August 2011). If approval is not obtained (the legislature will be concentrating on economic issues this session), the dates will slip to May or August 2012. The position: Visiting Professor, School of Business Administration. Contract is renewable annually for up to five years. Compensation: $50,000 - $60,000, depending on qualifications, plus standard fringe benefits (health, retirement, dental). Additional compensation, from project work, is possible. Expected Start Date: May 20th, 2011 or August 15th, 2011. Qualifications: â¢ Masters degree in Computer Science (software engineering specialization), MIS, Informatics or similar degree focused on software development and systems design. â¢ Extensive knowledge of Squeak (ideally Pharo), its extensions (e.g. Seaside), and libraries (CMS, version control, morphic, etc.) plus several years experience using Squeak to develop commercial or research applications. â¢ Demonstrated multi-disciplinary / cross-disciplinary commitment; e.g. multiple degrees, publications or teaching experience across disciplinary boundaries, multi-disciplinary honors teaching. â¢ Demonstrated ability to use a hybrid approach to instruction and mentoring, combining the use of on-line and in-class resources and techniques. â¢ The position does not required full-time residency in New Mexico, but will require at least 26 weeks of residency (in two to four week blocks), annually. Full-time residency is highly desirable, but not an absolute essential. Expectations: This position is unlike any other academic position, because of the unique nature of the program it supports. Faculty are expected to spend up to forty hours a week, while in residence, in the Studio working with students at all levels, and delivering academic content âon-demandâ and in a highly modular and accelerated fashion. Faculty are expected to define (and seek grant funding for) research projects and involve students in both the conduct of the research and co-authoring of publications arising from the research. Faculty may take on project management responsibilities (receiving appropriate additional compensation) for commercial projects underway in the Studio. The program emphasizes the ability to think and to employ multiple perspectives (systems, object, design, agile, and computational thinking) and faculty are expected to help students develop this kind of thinking capability â far more challenging than simply preparing them to pass a final exam. Program: This program is unique: in focus, in structure, and in terms of the demands placed on faculty. The stated goal of the program is to graduate students as full-participating members of a professional community dedicated to and capable of using computing and software technology to analyze and solve the âwickedâ problems confronting business enterprises, communities, and global societies. Graduates will be âmodern polymathsâ masters not of all extant knowledge but who have learned and integrated knowledge from multiple disciplines and domains. The program is experience-based. All students will spend significant amounts of time (up to thirty-two hours a week) in a Studio â simultaneously working on real-world projects for paying customers and learning new subject matter. Students will work side-by-side- with professionals (acting as project managers and guarantors of successful delivery) who will provide tacit knowledge and mentoring. [Faculty members are eligible, and encouraged, to assume this kind of professional role â for additional compensation.] The University works with one or more private sector entities, the latter responsible for contracting and managing projects, generating sufficient revenues to pay for professionals, student apprenticeship wages, and program expenses (e.g. travel to conferences). The program is competency-based (approximately 100 currently defined) and not course-based. All competencies are defined at seven different levels (from âunderstands concepts as evidenced by objective testâ to âmakes an original contribution to the communityâ) and student progress (and graduation) is based on number of competencies demonstrated at level. Curricular subject matter is presented in highly modular form (think in term of one-credit, 16 face-time hours) and utilizes a combination of on-line and self-paced study, broadcast (e.g. webinar format), and in-class workshops. Students define iterative and incremental âindividual education plansâ every eight weeks and those plans, collectively, defined the curricular material to be delivered. Knowledge integration and motivation for learning is provided by the project and studio context in which all instruction is delivered. The Studio is a âone-room classroomâ â all students, faculty, and professionals occupy the same room at the same time (much like the ideal Agile work room or the botegga where Leonardo was an apprentice and later a Master). Multiple projects are underway, with different groups working on different projects. The rhythm of the Studio is defined with iterative cycles, each beginning with a planning session and ending with a retrospective. Within the cycles are defined, repetitive, periods for special activities like reader and writer workshops, social activities, and learning âspikes.â We would like to provide the students with a comprehensive development tool and environment â Smalltalk/Squeak â as a foundation for all of their technical software development learning and activities. The use of a uniform environment will make it easier to focus on the thinking behind the technology and the analysis of problems and design of solutions. When marketplace and technical demands indicate, students will learn prevailing technologies (ranging from HTML to Java â to relational database) and new technologies (e.g. non-relational and document databases) as alternatives to the Smalltalk base. Students will leave with the same level of expertise and understanding of current mainstream tools and technologies as graduates of any other CS / MIS program; but they will also have the underlying foundation made possible with the common tool and environment. If this kind of radically different program and alternative academic appointment is of interest, please contact: (Vita is OK, but would prefer a simple letter explaining why this is of interest to you and a description of your qualifications.)
