tell us how what would help you? I thought about logging on the irc channel and mentioning who is fixing what. We will start from around 13h.

[Pharo-project] "The World of Smalltalk" launch

by Geert Claes

Hi everyone, Following the extremely positive feedback I received grouping all Smalltalk related mailing lists I have extended the initiative with a free informational website for anything Smalltalk under the name "The World of Smalltalk" on http://www.world.st www.world.st (nabble forums are on http://forum.world.st forum.world.st ) I decided to keep the website clean and simple and have not added any ads. I only added a gratuitous "donate" link on the "contact" and "about this site" page for those who want to make a voluntary contribution towards the domain registration cost or even for my time and effort :) I have only added the local smalltalk user groups which seemed still active and the events calender includes the upcoming events I was aware of as well as the UK Smalltalk User Group's shared calendar. Please feel free to distribute and/or link to the http://www.world.st www.world.st website (which helps with the search engine optimization) to guide anyone to the information they need. Any feedback regarding the site is also welcome! Cheers, Geert -- View this message in context: http://forum.world.st/The-World-of-Smalltalk-launch-tp2073793p2073793.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

It's close but not entirely correct. The computation needs to include the extra header word for "large" instances (> 255 bytes). Squeak has three possible header sizes: 1 header word - used by compact classes 2 header words - used by regular classes 3 header words - used by "large" instances BTW, SpaceTally>>spaceForInstancesOf:withInstanceCount: has the correct computation (except for 64 bit :-) > Is there a way to know this > but from the VM side also ? how ? > I really need it from the VM side :( but I have no idea how to do it. It's easy to do in the VM, just use this: primitiveByteSize "Answers the number of bytes the receiver occupies" | nbytes| self export: true. oop := self popStack. nbytes := (self sizeBitsOf: oop) + (self extraHeaderBytes: oop). self pushInteger: nbytes.

good point. It would be nice to have a diffusion on twitter as well. Something important, people who want to join need to sign the license agreement: http://www.pharo-project.org/license http://pharo.gforge.inria.fr/licenseDocuments/PharoSoftwareDistributionAgre… If you have problem to send surface mail, then send me a .pdf, I will mail to Stef.

The short answer is no, they just provide a different way of dynamically deciding what message you want to send. The closest equivalent would be the logic used to decide which ImageReadWriter subclass to actually use. Cheers, Henry
