Building and deploying your first web app with Pharo
Sven wrote a nice tutorial on how to build and deploy your first Pharo webapplication. It does not use any of the known Smalltalk webframeworks (like Seaside, Aida, Iliad, ...) - it requires only the Zinc HTTP components that are already part of the Pharo image.
He also explains how to deploy the final result to the cloud.

Redline Smalltalk Eclipse plugin
The Eclipse plugin for Redline Smalltalk moves forward as this screenshot proves.
Athens on Amber
Athens - the Smalltalk graphic framework that is now also part of upcoming Pharo 3.0
is also available for Amber Smalltalk.
So you can write your graphics code in Pharo first and run it later in Amber directly within a webbrowser.
A demo is here. You have to move the splitter in the middle of the helios IDE to see the "do it" button.
Nice!
Hopefully Amber and Pharo will continue to stay as much as possible compatible - then you can freely choose the appropriate platform for writing server side (Pharo or Amber on node.js), rich client (Pharo) or webbrowser (Amber) code in Smalltalk.

SourceCity for Pharo with CI job
SourceCity is a 3D visualization tool for analyse object-oriented systems. There is a new Jenkins CI job to build a "SourceCity" image right from the metacello config.
So you just need to download the image and run with the usual Pharo VM. To create a visualization just evaluate:
SourceCity exampleRpackage
Note that SourceCity is meanwhile open source with MIT license. Code can be found on SmalltalkHub.
Read more about the project here (page is a little bit slow) or here.

There is also some progress on a Sunburst visualization for Roassal. Click the image to zoom the screenshot:
Roassal with 3D support
The Roassal visualization engine for Pharo now also supports 3D. Here is a screenshot, click to zoom.
You can also view an older video to get more infos on how to use Roassal.

New class builder in Pharo 3.0
The latest updates of Pharo 3.0 contain a new class builder. Check out
PharoClassInstaller example
for an example.
This will end up in the support of "slots" - a slot is a meta-object for accessing a field in an Object. This makes class building also more explicit - for instance you can define the layout when building a class (PointerLayout, ByteLayout, ...)
So instead of having an instanceVariables array you can now have real layout objects. The implementation also includes field modifications which can track changes required to migrated instances (adding/removing fields, shifting position, ...).
Read more about Slots here.
