[Pharo-project] Experience using multiple images as a distributed datastore?

by Stephan Eggermont

Hi, I'm looking at alternative ways to break through the 4G 1 core border. Does anyone have recent experience storing data in multiple images and parallelizing calculations, perhaps similar to https://www.usenix.org/system/files/.../nsdi12-final138.pdf? With Ghost, Fuel and Zinc the building blocks seem to be there. Stephan

Re: [Pharo-project] [Elsewhere] The Web Is Becoming SmallTalk | Zackâs Blog

by H. Hirzel

Thanks Sven for the link. Yes, a one-page HTML/JavaScript/CSS application can be compared in a modest way the work with a Smalltalk image. But for us this means to stay with Smalltalk where it is possible as it offers much more. This issue is something for the Amber list, I think. --Hannes On 2/11/13, Sven Van Caekenberghe <sven(a)stfx.eu> wrote: > As read on new.ycombinator.com > > http://zacharyvoase.com/2013/02/10/smallweb/ >

[Pharo-project] OneClick for 2.0 available again

by Torsten Bergmann

Hannes wrote: >If I open the Pharo one click 2.0 on Windows by double-clicking on >'NBCog' I get a 'Choose file' dialog Yes, this is a problem with the (current) double-click build. See my post here: http://lists.gforge.inria.fr/pipermail/pharo-project/2013-February/074358.h… Quick fix is to just rename CogVM.ini into NBCog.ini and it works. We should make sure the INI file is always named like the VM. Background: =========== The (Windows) VM executable (if I remember the code correctly) looks for the image file like this: 1. If there is an *.ini file that is named like the VM executable (for instance NBCog.exe -> NBCog.ini or Pharo.exe -> Pharo.ini) then this INI-File is processed to initialize the VM. If this ini File contains an entry called "ImageFile" then it searches for the location given there. This is from old Squeak times and described here: http://squeakvm.org/win32/settings.html 2. If there is no ini File it looks in the current directory (usually the directory where the VM executable is placed when you double click in explorer) for a file with an *.image extension. If it finds exactly one then this is started. You can try this if you extract a VM and an image in the same directory. If the Windows VM does not find an image file or more than one files with the *.image extension (after multiple saves) then a file dialog is opened. This is absolut correct - but in the Pharo one-click the image is unfortunately not in the same folder as the VM. The directory layout for Pharo one-click uses a special "Contents\Resources\" subfolder for the image - maybe to have a cleaner root folder. This conflicts with this default searches... So if there is no ini file found and no image then it opens the file dialog. Bye T.

Thank you for your answer and the effort to bring the one-click back, Marcus. With the caveats you mentioned I can use it right now. Good to have an easy access again to the most recent Pharo 2.0beta without configuration effort. Just a one-click download and unzip action. --Hannes On 2/11/13, Marcus Denker <marcus.denker(a)inria.fr> wrote: > > On Feb 11, 2013, at 10:59 AM, H.

Hello, The one click is in a bad shape right now because we use wrong VM with a bad name, this will all we better soon. My priority was to get *any* kind of one click working again...
