Steve on Smalltalk

Stephan B. Wessels is a long term follower of Smalltalk and contributor to Squeak. On his blog "Plum street" (which has a nice design BTW) he shares some thoughts on Smalltalk and software development in general. A must read.

 

ESUG 2009 starts

ESUG 2009 conference in Brest, France will start tomorrow. Adriaan provides first pictures on his website from the Camp Smalltalk.

 

Avi Bryant on Trendly, Ruby, Smalltalk and Javascript

Interesting interview with Avy. Did I mention that (beside dabbledb.com) he already built a new website called trendly.com?

He also announced Clamato this week (a smalltalk dialect for javascript).

tier-1 mobile carrier performing real-time, nationwide call control

Dolphin Smalltalk Next Generation

Were getting closer to September ... would be interesting if the community will get more informations on the announced DNG (Dolphin Smalltalk Next Generation) beta release - (see here) about the DNG startup workshop in Tarvisio, Italy.

What is Dolphin Smalltalk Next Generation: easily said it is Dolphin Smalltalk (a very interesting Smalltalk derivate for windows) now running on the LSW virtual machine from Frank Lesser. AFAIK the first version will be a Dolphin 6 running on the new VM including with support for FFI and a pluggable JIT.
The new image should also be split up into many self contained "mini-images" (SLL's).

The last info I got was from here and there.

Interesting times ...

Magma High Availability

Chris announced release 42 of Magma, a multi-user object database written in Smalltalk. Beside Squeak this new release now also runs on Pharo which was already discusses on the Magma mailinglist.

But it is more interesting that a single logical repository can now be served from multiple servers simultaneously (each with an own copy). This introduces high availability which is explained in detail here.

Remote Control on Seaside images

When you want to remote control a headless seaside webserver image
(pharo or squeak based) you may want to choose VNC. There is a package already available called RFB (Remote Frame Buffer).

Miguel tweaked it a little bit these days. Read more here and here.

 

Cog status and FFI directions

Some update on the status of the Cog VM from Eliot. Nice.

Custom applications with Smalltalk

Before deploying a custom application/product written in Smalltalk
(here Pharo and Squeak) you may want to adapt your Smalltalk environment or even build a custom virtual machine. No fear ... it's easy.

I've written a short HOWTO that is now up on squeakvm.org.

There were others who tried to learn about Squeak's deployment possibilities -
like Jens Moenig with his Sudoku solver and Geneator which was also packaged as executable. But I hope this short docu will help others to easily build products with the current state of these free and open source Smalltalk implementations.

BTW: The Squeak Win32 VM now also has support for large cursors ... so when you write a game even the cursor is changeable.
