[Pharo-project] [ANN] Brltty support for Pharo
by Goubier Thierry July 2, 2012

July 2, 2012

Hi, I have created a project and release a start for connecting Pharo to Brltty, the software layer handling braille keyboards under Linux. This is the first step which could allow a blind user to use Pharo. The project is hosted on ss3, at: http://ss3.gemstone.com/ss/StBrltty.html At the moment, this code is only able to authenticate with the brltty server, not yet able to display anything (it's hard to read the brltty source code to guess the protocol used). There is some overall design to be done, because a braille keyboard is a fairly complex device (with input / tty keys, not a pure display device), even if my blind colleague is perfectly fine using it only as a display device and navigating with a normal keyboard. There will be a bit of Morphic adaptations to be done as well, such as keyboard navigation (it's not working very well at the moment in Pharo 1.3 and 1.4). I have the start of a proposal for funding, but I can't push this forward; I do believe an internship (L3/M1 in the french system) would probably be enough to get it to work. I do have a test setup : a user and two Braille keyboards with different characteristics. So, if anybody is interested to take over me ?

Hi, I am trying to insert a SVG component into a JQuery widget page. I have been able to insert it, but I am not able to manage the callback, because I do not know how to direct it to SVG component instead of to JQuery. Can anybody give me a hint? Many thanks Lorenzo

[Pharo-project] MongoTalk issue
by Esteban Lorenzano July 1, 2012

July 1, 2012

Hi, Ok... this is the problem: I have a customer who likes to add stupid unicode to his strings (like strange open-close colons, not the regulars). And of course, the BSON driver does not handle them well... in fact, it persist them well, but when customer tries to read it, it throws and error (Invalid type). So... I started to investigate and I figured out that problem is that when the answered string is a widestring, size readed and size expected can be different (depending on the amount of 2+ bytes characters on the unicode string). After some tries, I come this incredibly ugly hack that works: BSON>>nextSizedString | size result | size := stream nextUInt32. result := stream nextString. result isWideString ifTrue: [ stream skip: (size - (result collect: [ :each | each asString asByteArray size ] as: OrderedCollection) sum) - 2 ]. ^result LittleEndianStream>>skip: aNumber stream skip: aNumber as you can see... It "calculates" the real consumed bytes (which is strangely less than declared size) and skips to its real position minus 2. This works, at least in the examples I have at my hand... now... my questions: - I'm sure it has to be a better way to calculate the difference, but I didn't find a good one. - why that "- 2"?????? WTF... what does that means???? - can someone confirm that the fix works? (I have "production issues", I need something that works as fast as I can) Thanks, Esteban

Dear Pharoers and Smalltalkers This mail is really important so read it carefully. Especially the last part of the mail is important for the immediate future: we need your support and input. Read section ***Support*** at the end of this mail. Context ======= After taking into account feedback from companies and pharo users in different occasions and discussing with the INRIA lawyers and the team in charge of the administrative aspect of the consoritum here is the setup we finally want for the consortium. We will have two separated entities: - one french law 1901 association for individuals and - one consortium for institutions (companies, research groups, laboratories, universities...) managed by INRIA We hope that in the long run the consortium will be fully managed by the association but in the current bootstrap phase INRIA is a good solution. ============== The Pharo Association ============== The goal of the association is to promote Pharo. It will have its own web site. Individual Memberships (managed by the Pharo Association) ---------------------- There are two individual memberships - Individual Pharo Association Member: Yearly fee 40 Euros - Golden Individual Pharo Association Member: Yearly fee 99 Euros You will get a nice goody, reduction access to conferences, reduction for training and access to teaching material, be part of the pharo groups on social networks, be part of the pharoAssociation-individual-members mailing-list, get access and registered to the pharo association web site. Others (managed by the Pharo Association) ---------------------- The association will be able to issues bills so you will be able to buy a Pharo distribution when your organization cannot be a member, a sponsor or doing a donation to the Pharo consortium. End of Pharo Association Description =========================== The Pharo Consortium (managed by INRIA) =========================== The goal of the consortium is to structure and build an umbrella to foster business around Pharo and to promote Pharo. A company, user group, research group, team or institution can be a consortium member, not individual member. There are three levels of fees and corresponding benefits. You decide your degree of support. The annual fees are - Bronze 1000 Euros - Silver 2000 Euros - Gold 4000 Euros Consortium members main advantages are ---------------------------------------- Non individual members of the consortium get the following advantages: - privileged access to the core development team via a specific mailing-list pharo-core-team-for-members(a)lists.gforge.inria.fr - influence priorities of the next development. The member will be able to propose agenda points and items for the executive team. They will be requested one month in advance before the committee meeting. - get access to privileged core engineer time (to address pharo core problems) - Bronze member gets one day of engineering time + is automatically a diamond sponsor. - Silver + two days of engineering time + one job description for job dashboard + is automatically a diamond sponsor.. - Gold four + 4 days of engineering time + multiple job description for job dashboard + is automatically a diamond sponsor. - Training special prices and possibility to become pharo trainer - Pharo consortium member can also ask and pay for extra support days at INRIA engineer prices (around 600 Euros) per day. - Member can offer to their client access to the possibility to pay for extra support days at INRIA engineer prices (around 600 Euros) per day. - The core team can provide contact with experts for certain areas of development. Pharo Consortium Gouvernance: steering committee ---------------------------------------- The consortium will be managed as follows: There will be a steering committee and an Executive Team. * A steering committee is composed of one representative of each member (except individuals). * The chairman of this committee will be Inria * Steering Committee Role : - The Steering Committee follows the execution of the PHARO R&D Team - It validates and gives input about the task list of the Executive Team. - It can propose members of the executive team. - It prepares, organizes conferences, seminars or other animations to promote PHARO and have new members - It revises the annual fee * Decisions taking: after consultation and collect of representative member points of views, Inria takes the final decision. * The steering committee will communicate via a private mailing-list. It may meet physical once a year. * An agenda to reach conclusion will be established by Inria on proposals of the members (the members will be queried a month in advance). Technical Executive Committee (akaR&D task) ---------------------------------------- * The Executive Team is composed of members proposed by the steering board and RMOD Team * Its roles is to * Study, analyze and validate external contributions for PHARO * Report to the steering committee * Present a task list to the steering committee. * Propose, schedule and implement tasks in conformance with the tasks list. * Coordinate the release Pharo and its VMs Pharo consortium Sponsoring --------------------------- Orthogonally to memberships, an entity can be a sponsor of the consortium without being a pharo consortium member. Pharo consortium are de factor platinium sponsor. Sponsors will get their logos name exposed to the consortium web site. There are two kinds of sponsors: - normal 500 Euros - diamond 1000 Euros Job board --------- Non consortium member companies will be able to pay a fee (1000 Euros) to post job offers to the job board. End of Pharo Consortium Description ===================== *** Support and Answer needed*** ===================== To be able to pay an engineer by the consortium, INRIA needs to make projection, build budget, pay attention to visa and other important administrative tasks. To deal with the risk that the consortium may not collect enough to pay a full salary we are considering to ask INRIA to help us financially. To do so we have to give some concrete figures to INRIA and motivate our request. In addition, our team (RMOD) on its own budget will try to compensate by allocating extra resources However, this will be only a one shot. In addition, some of our team members have been approached by google to work on chrome and dart Virtual Machines. So if we really get a future we should build it now. Many of you told us that they want to support the consortium, now we need to know what would be amount of membership, sponsoring you could give. So please read carefully this mail and send us a mail at stephane.ducasse(a)inria.fr with the same subject than this one. We will collect the information and build a case to present to INRIA. Thanks in advance for Pharo and for the future that we are building together. The RMOD team and the Pharo board

[Pharo-project] Odd inconsistency in Seaside One-Click 3.0.7
by Lawson English June 30, 2012

June 30, 2012

I was reviewing the Seaside book while refreshing my skills, and I noticed this very strange, trivial, but fundamental bug/inconsistency: http://www.youtube.com/watch?v=2RyREN00Nok (less than 2 minute demo). The issue is hardly worth mentioning, except for totally new users, but I DO wonder what is going on that changes the behavior from the first right-click on the category pane to the second. L -- Squeak from the very start (introduction to Squeak and Pharo Smalltalk for the (almost) complete and compleate beginner). https://www.youtube.com/playlist?list=PL6601A198DF14788D&feature=view_all
