Smalltalk-80 on the iPhone

Here is a video on running the old ST-80 on the iPhone.

Magritte 3

Nice video on Magritte 3.

Voyage - persisting objects

Voyage is another approach in the Smalltalk/Pharo world to persist object models. It was written by Esteban Lorenzano, I think mainly with the goal to persist data from Pier (the CMS system) images.

You will find his slides from the Pharo 2012 conference here. Francois Stephany is a beta tester and is already blogging how to use Voyage in conjunction with MongoDB.

The code can be found in the Voyage project at smalltalkhub.

PharoConf Slides and Pictures

The slides and pictures from the pharo conference are available.

Amber in use at SmalltalkHub

http://smalltalkhub.com is not only a new website for Smalltalk. If you look at the bottom of the page you will notice that is based on Pharo, Seaside, MongoDB and also the client side Amber Smalltalk that helps running the nice looking pages.

If you have have Google Chrome just hit F12, go to the JavaScript console and evaluate:

"smalltalk.Browser._open()"

to open the Amber class browser. It is very nice to see the classes in Hub-Amber-... categories and I like how easy one can understand and encapsulate client side rendering.

Hope to find some time to dig deeper into Amber especially after Nicolas has some nice ideas to push Amber.

CogVM Object format

Guillermo explains the details of the CogVM object format in a blog post. I already mentioned Marianos blog that should also help you digging deeper in virtual machine building and related technology. Currently there is also a discussion about a new object format that Eliot want to introduce. If interested check out the vm-dev list.

Destroy all software (fun)

After watching this video I opened a Smalltalk image and tried things like "#() + #()" and the like.

Historical Documents on Smalltalk

ESUG provides a folder with historical documents on Smalltalk.

Concrete Type Inference

There is a new blog on ConcreteTypeInference in Smalltalk

Zinc Documentation

Sven provides some docu for the Zinc HTTP framework in Pharo.

Fuel Release Version 1.8 and graph visualizer

There is a new version 1.8 of Fuel available. The nice thing is that it now includes a visualizer based on Roassal.
This allows to easily debug Fuel.

Note that the repository is now moved to SqueakSource3

Squeak on top of JavaScript Linux in the web browser

Exotic but possible: Squeak virtual machine now also runs on JSLinux using the mini.image. 
JSLinux is a x86 PC emulator written in JavaScript and running in a web browser.

Here is the video and announcement from Pavel.

I expect more and more emulators running on top of JavaScript. Maybe one day it is fast enough to load and run Windows or Ubuntu on top of the JS engine right within your pc/tablet/phones web browser. Interesting times...

CodeMirror - Styling Seasides WABrowser

I wrote a simple seaside wrapper today for the CodeMirror JavaScript Editor, the code lives in

    http://ss3.gemstone.com/ss/Seaside-CodeMirror

It was actually very easy to wrap due to the new WAFileMetadataLibrary facility allowing for nested folders in latest Seaside versions.

Since this editor includes also a "Smalltalk mode" you can also use the project in combination with a simple patch changeset for WABrowser to style your web served Seaside code browser/editor:
 

PDF4Smalltalk

Christians PDF4Smalltalk library has a new home and mailinglist.

Oniguruma

Oniguruma is a regular expression library which is standard with Ruby 1.9. Now there is a binding for VisualWorks Smalltalk too.

LivelyKernel - ideas from Squeaks Morphic brought to the webbrowser using JavaScript. Interesting demos:

• Lively Kernel on 3D cube
• SyncMorph
• Lively Kernel 2 - Connections example
• Morph Interaction on iPad (with details here)

Check out the webpage or even try the new Lively3D

DrGeo Android release

Hilaire Fernandes made DrGeo for Android available. DrGeo is built using Pharo Smalltalk.

Timeouts in Smalltalk

Thats why I like Smalltalk (and Blocks) - powerfull and easy to understand:


[ self doSomething ]
valueWithin: 1 day
onTimeout: [ self doSomethingElse ].

STON - Smalltalk Object Notation

You may know JSON format from JavaScript - now Smalltalk has something similar. It is called STON - Smalltalk Object Notation and infos about it can be found here.

Artefact - PDF framework for Pharo

Oliver created a PDF Framework for Pharo called "Artefact". Nice to have a new alternative.

In the past I used my LibHaru wrapper for Pharo - but that one requires a native library. Christians work generating PDF directly in Smalltalk is only available for VW and not yet ported to Pharo.

2nd favorite language

Just stumbled over this presentation from Eric Clayberg with an introduction to Dart for Smalltalkers. You can also watch the video here. As you may know Dart is an attempt from Google to provide a better language than JavaScript for structured web apps. Its interesting and in my spare time I follow new Dart development by looking at dartlang.org or Dart news on Google+.

One interesting thing I noticed is that Eric's presentation is dated March 2012. Nothing special for you. But at least something that made me personally think. Exactly 12 years ago in March 2000 we both attended the first CampSmalltalk in San Diego where a bunch of Smalltalkers gathered to make the world a better place and have a great time. It was my first visit to the states and yes - we all had a great time.

At the Camp Eric had a few copies of the original Smalltalk issue of the BYTE magazine and I got the last one he had left. I was so happy about this historical trophy - it still has a special place in my library!
Eric is meanwhile working for Google as Engineering Manager for the new Dart Editor at Google. One of his slides in the Dart presentation is:

"Let us know if Dart is your new 2nd favorite language :)"

I have to admin I'm not sure what my 2nd favorite language is. There are many nice languages out there:

• Is it JavaScript since it is widely present and IMHO the dynamic languages with the best adoption
• Is it Dart since its new and better structured than JavaScript?
• Is it Groovy which is a nice scripting language for the JVM with Java, Lisp and Smalltalk roots and Smalltalk syntax on the wish list.
• Is it Amber since it allows me to run Smalltalk on JavaScript
• Is it Java since I (have to) use it in daily work and is the most wide spread
• Is it SQL since (relational) data often survives code/programs?
• Is it C since stupid TIOBE ranking says it has now overtaken Java.

When I look back these 12 years many new languages have evolved and I like that now more and more people turn to dynamic languages since they now see the benefits to build dynamic systems. Unfortunately only a few walk in to metaprogramming. So it's not really clear to me what my 2nd favorite language is.

But I know what my first favorite language is and the programming future still has to be invented.

Inside OOVM

Kasper V. Lund (who is now working on Google Dart Language) provides a link to his Master thesis which he wrote with Jakob R. Andersen called "Revolutionizing Embedded Software".

Both worked together with Lars Bak in the OOVM team. Lars should be known to you from his V8 JavaScript Engine implementation in Google Chrome, the Strongtalk project and others.

OOVM is a Smalltalk based virtual machine that allows programmers to hook in remotely and modify code on the fly without needing to reboot the environment.

This VM allowed you to connect to running embedded devices and directly manipulate every object, class, or method. Which is a very known concept for us Smalltalkers since the beginning it allowed interactive programming environments for embedded system developers as well.

However - interesting paper.

GSoC Update

13 stipendiums got accepted by Google for Smalltalk! Great work and a good investment into the future.

Pharo: from Kernel to Core

As I already posted Pavel is working on a small Pharo Kernel. The idea is to have the Pharo core image, throw out packages to find a minimalistic kernel image and by loading the packages back prove that it is able to boostrap Core from Kernel again.

Pavel is now using Fuel to load the core packages back into the kernel image to recreate a Pharo Core image. As you can see and read here this really speeds up the process.

Smallsource

Smallsource is a project from Dale to allow you to store Monticello packages
within the file tree. This allows you to use traditional versioning
systems like Subversion or Git from Pharo Smalltalk.

Check out the README of the project.

Dale gave a presentation on this called "Practical Git for Smalltalk"

Snap!

In the tradition of Squeaks Morphic and the Scratch platform there
is a nice library for JavaScript with a morphic implementation to BYOB
(build you own blocks). Version 4.0 is still in pre-alpha status, but here's a preview available.

The current result looks really good. Details can be found on Jens Mönig's blog.

Then check out this page: http://pharoconference.eventbrite.com/

Extended File Library for Seaside and Twitter Bootstrap

Subclasses of "WAFileLibrary" allow you to serve static files directly from Seaside without the need for a stand-alone server like Apache.

This is nice - but unfortunately they were all served in the same resource folder/url. If you look at most JavaScript components then often separate folders for CSS or images are used which can be very tricky if you want to wrap them in Seaside.

But there is help: Nick Ager works on an improved WAFileLibrary.

He also used this to wrap the Twitter Bootstrap library, check it out at:

http://twitterbootstrap.seasidehosting.st/

Object profiling

Looks like there is now a new small company founded to help profiling software. They use VisualWorks and Pharo and they use their own MIT licensed "Kai" and "Hapao" projects. I already reported on "Hapao" earlier.

VAST Videos

Nice - a new page for videos from Instantiations about VAST (Visual Age Smalltalk) and Smalltalk in general.

Squeaksource.

The development repo is at the Squeaksource 3 instance at HPI Institute.
Its open for read write - so if you want to contribute...

EToys 5.0 Beta 2 is ready

... for you to try out.

Smalltalk and CI

Pharo already provides a CI server for daily builds:

http://ci.pharo-project.org

I personally use it to get the latest versions and you should do as
well if you are interested in up to date images.

Now some work is going on in the Squeak community to reuse the build
scripts from Lukas as well and I think we can soon expect

http://www.squeakci.org

to fill up with Squeak CI built images. Cool and a big thanks to the people providing that!

Pharo Smalltalk in use ...

Styling your (VisualWorks) Smalltalk app

There are Smalltalks with native UIs (native widgets painted by the underlying OS) and other Smalltalks who paint the windows and widgets themselves.

With the last ones you can even built an own "Cross-Platform UI Look" like this UI example from a VisualWorks based product from http://www.cognitone.com shows.

Play with Arduino and Pharo

In case you want to play with Arduino and Pharo Smalltalk then check out this blog post.
