Re: [Pharo-users] PBE.image

by Robert Shiplett

Would someone please create that PBE image. Many young innovators think Smalltalk has NOT been used for years - and they have inexpensive Linux netbooks with enough RAM and SSD capacity - everything we lacked when Smalltalk was a choice versus C++ ... and then versus Java. I meet international MA students in CS here and recent BA grads (many are international students going home now) who really think Smalltalk was some research experiment at Microsoft or Apple ... and certainly never used by a bank or an insurance company or a natural gas trader or grain futures trader and definitely not by a telco. They are unaware of the connection of Ruby to ST let alone JavaScript to Self and if they have heard of Traits, they were invented in Scala not Self ... they have never heard of Alan Kay or Dan and the young women have never heard of Adele G.

Re: [Pharo-users] PBE.image

by Mariano Martinez Peck

Hi. There was a change in the last years in Pharo and we have a new VM called CogVM which is the default since Pharo 1.1.1. So, Pharo 1.2.1 one click may probbaly be using a CogVM. CogVM cannot open "old" Pharo images. I guess, that PBE.image is an "old" Pharo image, say 1.0, and hence, cannot be opened with a CogVM. So....you should try a non-cog VM. For example, you can try the same you did but with http://gforge.inria.fr/frs/download.php/27303/Pharo-1.1-OneClick.zip Or...ask if someone can recreate a new PBE.image cog compatible. Good luck.

PBE.image

by bb

I run Pharo on Linux and tried to start Pharo with the PBE.image, that is offered as an add on to the Pharo by example book. I copied PBE.image and PBE.change to Pharo-1.2.1-OneClick.app/Contents/Resources/ (where pharo.image and pharo.change reside as well) and changed the last line in pharo.sh from "$ROOT/Contents/Resources/pharo.image" to "$ROOT/Contents/Resources/PBE.image" When I start the shell-script nothing happens. What is wrong with my experiment. With pharo.image pharo starts properly. I tried to change the setting in pharo.ini from pharo.image to PBE.image as well. No success! What is wrong?

Needed hooks to replace ImageSegment and ReferenceStream by Fuel?

by Mariano Martinez Peck

Hi guys. Stef/Marcus are proposing to replace ImageSegment and RefenceStream by Fuel. Maybe in Pharo 1.4 or in the future. So, I need help to understand mostly the required "hooks". So far, I am aware of: *ReferenceStream* 1) #comeFullyUpOnReload: aReferenceStream This message is sent once the object is read from the stream, at materialization time. We already have this in Fuel and it is called #fuelAfterMaterialization 2) #objectForDataStream: refStrm This message is sent once the object is going to be written into the stream, at serialization time. The idea is that an object may not serialize itself as it is but something different. Most of the times, it is a DiskProxy, but not necessary. This doesn't go with the idea of Fuel, where the objects do not decide theirself how to be serialized/materialized but instead delegate to a cluster. 3) #applyConversionMethodsTo: objectIn className: className varMap: varMap This is for class shape changes. We will have another protocol. 4) #storeDataOn: aDataStream This message lets an object decide how to be serialized. *ImageSegment* a) #startUpFrom: anImageSegment Almost the same as 1). So....I am missing more? opinions? which of them are really used hooks? Thanks -- Mariano http://marianopeck.wordpress.com

Hi simon May be it could make sense to have a Pharo link and news... But this is up to you. May be you are not aware of our activity - some people told us that they cannot follow our pace. At least Pharo-cast. Squeak-fr does not really exist anymore, it was rename smalltalk-fr.

As a side point, when setting up world.st I have been looking at options to better integrate the planet.smalltalk.org stream but so far I have not been able to find a way that makes it look smooth, the venus powered planet's styling is just too different. I even experimented using a Google Reader Bundle with planet.world.st but I still don't like the way that looks either. -- View this message in context: http://forum.world.st/planet-updates-help-needed-tp3600734p3601659.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
