Fuel API bug
by StÃ©phane Ducasse Aug. 22, 2013

Aug. 22, 2013

Hi guys can you rename this method? on: aCollectionOrStream do: aBlock "Evaluates a block with a new stream based on the collection or stream. Answers the result of the block evaluation. Follows the style of FileStream>>fileNamed:do:." | aStream | aStream := self on: aCollectionOrStream. [ ^ aBlock value: aStream ] ensure: [ aStream close ] Please do not use on:do: for something that is not about exception (and announcements). It is too confusing and refactor after. Stef

new Cog VMs available
by Eliot Miranda Aug. 22, 2013

Aug. 22, 2013

http://www.mirandabanda.org/files/Cog/VM/VM.r2776/ CogVM binaries as per VMMaker.oscog-eem.333/r2776 * Speed-up Newspeak significantly (e.g. -28% in one compile-intensive benchmark) by maintaining unpaired methods (compilations of anonymous accessors) on a linked list instead of searching the entire method zone. * Make primitiveObjectAtPut fail if changing the header word and the new header has a different literal count. Avoids crashing the VM when inadvertently changing the header, as a Newspeak bootstrap did recently. * Implement frameless inst var store from arguments, so e.g. Point>>setX:Y: is frameless. * Add Cogit support for clean blocks by scanning literals looking for BlockClosures on the current method. -- best, Eliot

Updating the Pharo Contributors listing
by Sven Van Caekenberghe Aug. 22, 2013

Aug. 22, 2013

Dear Fellow Pharoers, As some of you may know, we have a page listing Pharo Contributors http://www.pharo-project.org/community/contributors This page was manually constructed and urgently needs an update. Based on the code behind the Pharo Consultants page http://consultants.pharo.org we want a similar data driven, statically generated page for Pharo Contributors http://contributors.pharo.org the new page is based on some of the old data, but needs updating. Many people are missing as well. So please, please, edit the template and send me your new or up to date information. PharoContributor new name: 'StÃ©phane Ducasse'; id: 'stephaneducasse'; email: 'stephane.ducasse(a)inria.fr'; website: 'http://stephane.ducasse.free.fr/'; description: 'Research director at INRIA Lille leading the RMoD Team. Pharo board member and president of ESUG.'; image: 'http://stephane.ducasse.free.fr/StefFingerOnNose128.jpg'; yourself PharoContributor new name: 'Camillo Bruni'; email: 'camillobruni(a)gmail.com'; description: 'Cosmopolitan Swiss Hacker, currently at INRIA'; yourself Some notes: - id is only needed when your name contains non-ascii characters - email will default to pharo-dev(a)lists.pharo.org if missing - website will default to a Google search for your name if a URL is missing - image can be omitted if you have a Gravatar, else it becomes a smiley - images will be rescaled to fit in 128x128, the URL needs to remain accessible - description is a pure text String, no markup is allowed - the description does not have to be too formal - the page is statically generated, only then do changes take effect Regards, Sven, on behalf of the Pharo Board. PS: If you are curious, the code for generating this page can be found at http://www.smalltalkhub.com/#!/~Pharo/PharoPeople

Jenkins slaves
by Christophe Demarey Aug. 22, 2013

Aug. 22, 2013

Hi all, An hypervisor used to host slaves for the continuous integration service is reaching its maximum storage capacity (primary storage used for running Virtual Machines). To avoid VM corruptions, we preventively stopped VMs running on this hypervisor. For the pharo ecosystem, following VMs are impacted: pharo linux-ubuntu-10-04 test2 pharo-contribution linux64-2 74 rmod windows-7-32 They will be restarted once the storage will be extended (probably in the beginning of the next week). If really needed, it is possible to create new slaves to substitute to these ones since they will be hosted on another hypervisor. Apologies for the inconvenience, Christophe.

The future of SqueakSource
by Andrei Vasile Chis Aug. 21, 2013

Aug. 21, 2013

Hi all, We will shut down the SqueakSource image at the end of next week (30 August 2013). The current system will be replaced by a simple view of the file system containing just the publicly visible projects. As meta-data, each project will have it's overview page attached (showing the licence and its author). Please forward this email to other mailing lists. Cheers, The SCG Team

reflection examples
by Tudor Girba Aug. 21, 2013

Aug. 21, 2013

Hi, I am preparing a set of talks that have reflection at the center. Obviously, I want to use Pharo to demonstrate reflection. I am now looking for examples that can be explained to programmer newbies (actually, managers). I am particularly looking for examples that include adaptation (not just inspection) and that can show that reflection is valuable. I already have some examples in mind, but they might not appear particularly valuable. For example: - inspecting a class: Object methods. - adapting a class: Object compile: 'answer ^ 42'. Any suggestions? Cheers, Doru -- www.tudorgirba.com "Every thing has its own flow"
