Request for adding Smalltalk syntax highlight in SE network

by HernÃ¡n Morales Durand

I have requested for some justice to stop the look down on Smalltalk syntax highlighting in StackOverflow: http://meta.stackoverflow.com/questions/272327/syntax-highlighting-for-smal… Maybe more votes (from you) would better support the request. Cheers, HernÃ¡n

Re: [Pharo-users] [Pharo-dev] Data Analysis in Pharo

by Tudor Girba

Indeed, this is nice! It is for this reason that Moose is a data analysis platform, and what we see now is just only tip of the iceberg, Once these tools get embedded deep in the environment the potential simply explodes.

Data Analysis in Pharo

by Alexandre Bergel

[sorry for the cross-post] Dear all, There has been quite some work around analyzing non-software related data. The teams of Serge, Thierry and Noury have been doing wonderful things. I am not sure you are aware of this, but I found this a nice achievement of what our community can do. Using sensors networks in Jakarta, Indonesia, to monitor floods. https://www.facebook.com/ObjectProfile/photos/a.341189379300999.82969.34054… CAR: Components, Agents, and Robots https://www.facebook.com/ObjectProfile/posts/704750642944869 Fantastic model from the Vietnam crew working on Ebola spreading https://www.facebook.com/ObjectProfile/photos/a.341189379300999.82969.34054… Another picture from the crew studying Ebola. https://www.facebook.com/ObjectProfile/photos/a.341189379300999.82969.34054… Ebola fatalities in Guinea. https://www.facebook.com/ObjectProfile/photos/a.341189379300999.82969.34054… Visualizing Astronomy pictures https://www.facebook.com/ObjectProfile/posts/702429986510268 Visualization of Network Latency by Leonel Merino http://t.co/xJN6qk1AEG Being this work, there is quite some sweat. This work does not happen randomly, and their authors deserve our encouragements. I do not know if this make sense to crosspost all these urls (looks like a spam isnât it?) but I am really happy to see all that happening.

About my sluggish image, I emptied the btree and it's ok now, I can live with it until I reload a new image. I hunted this reference for a moment, and gave up right now. I tried to make a reference counter to help finding roots of the references but got a lot of problems... I will look more deeply at PointerExporer and Fuel when I'll have time. The good thing is that I (think I) learned a bit about BlockContext, MethodContexts and so on ... :)
