Hi, I wonder if a pharo sprint could be possible at Smalltalks 2010. If there are people (more than me), interested, I can contact Smalltalks 2010 organizers in order to get a place/horary for it. Cheers, Esteban

by StÃ©phane Ducasse

Hi guys We would like to go beta for the end of the week or beginning/end of next week. It would gives us one month or two to produce 1.2. So we could have 1.2 for the beginning of the year. We could start 1.3 unstable around end of Nov. What do you think? Stef

Kudos to them, it's an outstanding service to the community! But since it is not hosted on a squeak.org server, it does no good to notify the Squeak box admin team when squeaksource.com goes down. OTOH if source.squeak.org misbehaves, then the box admins are the right address. - Bert -

I encountered this behaviour onsite (i.e. here at HPI) whenever a student tried to upload a MCZ, and it failed or hanged, the SqueakSource installation went haywire. So, whenever you encounter failing or endlessly hanging uploads, pleas tell the mailing lists or the box admins, so that squeaksource can be bought up again quickly. So long, -Tobias

I think you're taking me wrong. I agree that stateful traits are more useful than non. I'm trying to discuss the engineering of them.

So, according to the policy, Preferences should be available till at least 1.3. the preferences class is just there in 1.2 to help people loading their code. but the behavior is gone. Settings were introduced in 1.1 (but not used) so that people can migrate their code in 1.1 to save it in 1.2.

I fixed some of the preference issues (i didn't upload it yet), but it's a PITA to make it work in Pharo 1.2, because too many things were changed and are therefore broken.

So, you always have to pass a script that restarts the server? This sounds like a workaround, right? Cheers, Doru On 26 Oct 2010, at 21:48, Lukas Renggli wrote: > Ok, I think I solved the issue.
