Title: VM simulator in Pharo Level: advanced Possible mentor: Esteban Lorenzano Possible second mentor: Guillermo Polito Description: The VM simulator is a very useful tool when it comes to understand the VM behavior and debugging. However, it does not work in Pharo since long time due to API changes in the core of the system. This project is about bringing the simulator back to life in Pharo to enhance the VM debugging activities. Technical Details: The VM simulator must be ported (or better adapted) and supported by tests. Benefits to the Student: - learn a VM architecture using a higher level language such as Slang to build a VM - understand how several VM components work by debugging and testing them Benefits to the Community: The community will have a tool to debug the VM and be able to evolve it easily.

Dear Pharoers, Ideas are slowly coming, 14 so far, but this is way below the 30+ in previous years. So, stretch your brain, come with some more ideas, which will be interesting for potential students and of course useful for our community.

Thanks to everyone! I am moved not only by volume of people stepping up to take care of our community, but the quality of the plans and suggestions. I can't wait to see the videos! ----- Cheers, Sean -- View this message in context: http://forum.world.st/Video-registration-of-Pharo-Moose-days-tp4678184p4678… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

I would If I had time enough ;) paper deadline on wednesday, so until then I don't have much time at hand. I did a rough estimation. Using quicktime screen recording in high quality yields roughly 1GB raw video for 30mins. And the less you move stuff around on the screen the smaller the video :P. I used a fairly small terminal font and everything was sharp and readable. To get a decently compressed video I used the opensource MIRO video converter http://www.mirovideoconverter.com/ and exported the whole file as mpg4 compressing roughly by a factor 6. So that will be ~150MB for 40mins, that should work.

Perhaps we can meet the evening before and try the equipment in the real environment. And having the beer after that;-) -- View this message in context: http://forum.world.st/Video-registration-of-Pharo-Moose-days-tp4678184p4678… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

I also will have trouble attending from Australia and would appreciate that. Also it be good general PR longer term. I'd be happy to donate a small amount for a few beers for the volunteers, if there was some mechanism to receive that. Perhaps the Association could handle that? Or perhaps the lowest overhead would be transferring to someone's personal account. cheers -ben Johan Fabry wrote: > I cannot go to this event, so I would appreciate these videos A LOT.

If you can make it into a 30 second teaser, or even a 6:40/20slide pecha kucha, we could even publish them already. Doru: will there be a default presentation machine with screenflow?

A multi-cam setup would be great. Being able to switch from question to answer view helps. That would require one camera to be in front/to the side, facing the public. I don't know how practical that is with the available room (and camera zoom). Stephan
