VirtualGPU quick demo

The VirtualGPU is a simple DSL/framework for parallel algorithms. It is implemented in Pharo and available on SmalltalkHub.

In this quick video Ronie Salgado will show the performance and the simplicity of this framework, by using as an example simple vectorial and image processing operations. The structure of this DSL is inspired by the VirtualCPU made by Igor Stasenko et al, and numerical programming such as Matlab and GNU Octave. This DSL works by composing simple OpenCL kernels.

Dynamic Code Evolution VM

Found that on the web:

The Dynamic Code Evolution Virtual Machine (DCE VM) is a modification of the Java HotSpot(TM) VM that allows unlimited redefinition of loaded classes at runtime. The current hotswapping mechanism of the HotSpot(TM) VM allows only changing method bodies. Our enhanced VM allows adding and removing fields and methods as well as changes to the super types of a class.

Nice - should move Java a little bit closer to Smalltalk.

GetOpt for Pharo 3.0

When working with Pharo Smalltalk on the commandline there is already some support in class CommandLineHandlers to retrieve arguments and options. Now Phillipe Back has improved this even further by making Ian Piumarta's GST GetOpt work in Pharo 3.0.

You can load the code from SmalltalkHub. Getopt should be known to you if you ever work(ed) in C/C++ world. It automates some of the chore involved in parsing typical unix command line options. Java has something similar with CLI.

With Phil's project for Pharo it is now fast to use command line options and it allows also easy to debug them in the most lively environment you can work with.

Swiki in Squeak 4.5

Swiki was and still is one of the best (and most easy to use/maintain) implementations of a wiki. It is written in Squeak Smalltalk and I usually use the Winterlong release back from 2005. With it a Swiki server is easy to setup (just unzip and run) and as it stores the files in XML they are easy to backup, repair or query.

Now Chris got Swiki working in a recent Squeak 4.5. image also. Nice!

Pharo Seaside : Looking at HTTP Traffic

If you want to easily look at the HTTP traffic in your Pharo based Seaside application then just evaluate:

       ZnLogEvent open

This will open an spy on the Zinc announcements. Then start your server using:

     ZnZinServerAdaptor startOn: 8080.

and use the webbrowser to browse your Seaside application. You will now see any HTTP exchange between the client and the server.

The video demonstrates this:

Teapot - another way for Pharo to serve the web

There are various options to write web applications in Pharo. You can use Seaside or Aida web framework or play with the new Tide framework connecting Amber with Pharo.

If you want to quickly write something you can use the plain Zn framework as this nice tutorial from Sven describes.

And now there is something inbetween that allow you to quickly write an application that serves static or dynamic content from Pharo. It is called Teapot and with a few lines of code you can provide JSON to the outside world or other REST based functionality. It also includes support for the Pharo port of Mustache (the templating engine).

The basic concept of Teapot is to define one or many URL Route(s) - either direct or as pattern (for instance with a Regexpression) and return an appropriate response from the Smalltalk side. Simple, lightweight and easy to use.

Fun with Pharo (when writing books)

Beside the Pharo by Example, Deep into Pharo and the Pharo Enterprise book (available on CI, GitHub and as PDF) there is now also the idea of a book about "funny" things like implementing games in Pharo.

Therefore a new clone of the Pharo by Example book was created with the name "Fun with Pharo". The book is built on CI, the books source is hosted on GitHub and currently it includes already infos on how to build a digital Tamagotchi with Smalltalk or how the PhlappyBird game works.

The PDF for "Fun with Pharo" is already available.

If you want to contribute you should have a look and learn about Pillar and I would recommend to use either Online PillarHub or the new one-click image for PillarHub that you can run locally to write an own chapter.

   stream sendCommand: aString.
   stream close.


A one click image for PillarHub is available now on CI. You can now run it locally very easy.

Just download (for instance using PharoLauncher), run and check http://localhost:8080

Beta Test Scratch on the Pi

The Pi version of Scratch (based on Squeak Smalltalk) is available for beta testing. Feel free to help moving it forward.

It is not the only implementation: Phratch (based on Pharo Smaltalk) is basically running on the Pi too.

You may ask what are the differences between Scratch and Phratch: if I understood correctly from the discussion on the lists I think the Squeak version now has a paid maintainer (Tim Rowledge) and follows the original Scratch for kids. Phratch from Jannik Laval is more oriented towards a "Scratch for grown ups" and tries to profit from the cleaned up Pharo system and infrastructure.

BookOfTrees with CodeCity

The "The Book of Trees: Visualizing Branches of Knowledge" also includes also the CodeCity tool. Nice!


If you follow the Squeak and Pharo development yoou may know that there is a package called "FFI". This package provides a foreign function interface so you can call external modules on your operating system like Windows, Linux and Mac. So you were able to call external shared libraries, for instance a DLL written in C. FFI was originally written by Andreas Raab.

After FFI there was another package called "Alien", designed and implemented by Eliot Miranda which had additional support for callback.

After all that there was a new external interface implemented by Igor Stasenko for Pharo called NativeBoost, that not only allows to call external functions but if you like directly generate native assembler code using the AsmJIT port for Pharo.

While FFI was and still is a loadable and usable package in Squeak and Pharo, the newer NativeBoost (NB) package is now also part of the standard Pharo image. There will also be a chapter on NB in the upcoming Pharo Enterprise Book.

Most of this work is bound to x86 CPU architecture (I know was/is work going on to provide ARM support in AsmJit as well).

But this is just a summary of the history and current state. What is new is:

As you know new devices like the famous RaspberryPi run ARM processors. Now Douglas McPherson provided/announced initial FFI support for ARM architecture this week and the VM maintainers currently integrate.

All existing FFI tests now already pass for ARM (at least on Raspberry Pi). Really cool!

James Robertson

This blog post is devoted to James Robertson - I was deeply saddened by the news of his passing last week.
My deepest condolences to his family and friends.

We both shared a common interest in spreading technical news on Smalltalk, dynamic languages and OOP technologies as we both devoted our technology blogs to it - often pointing to each others news items.

We first met personally in March 2000 in San Diego - as part of a group of crazy people coming together for hacking on various stuff to unify and harmonize the ST industry world with the first CampSmalltalk.

Following his example I started blogging in 2004 and over the years we exchanged a bunch of emails, comments and posts on technical topics.

I enjoyed reading his blog, was listening to every single episode of his "Industry Misinterpretations" podcast series, used his BottomFeeder aggregator, enjoyed his videos from conferences that I missed and I appreciated his short videos on how to use various technologies. James - thanks for all of that!

The amount of work and time you devoted to moving us all forward is just amazing. You will be missed!

FontAwesome is (as you may know) an iconic font designed for the user with Twitter Bootstrap.

I now created a "FontAwesome for Seaside" project - which is a small Seaside wrapper for the FontAwesome project (using the latest version 4.0.3).

This is intended as an addition to the already available "Bootstrap for Seaside" project that I wrote and both should allow you to give your Smalltalk based web application a nice stylish look.

The project is located on STHub, there you will also find the documentation. A live demo can be found on http://pharo.pharocloud.com/fontawesome.

To try yourself load it from the Pharo 3.0 configuration browser or read the docu to see what is required.

Artefact PDF

Artefact (the PDF framework for Pharo Smalltalk) has a new website:


Any progress?

Found this quote on twitter:

"meanwhile Oracle is making Java slowly, slowly look more like Smalltalk. We'll probably get there by 2080"

I have a similar impression. For example in Java 8 you can now write:

"HelloWorld".chars().forEach(each -> System.out.println((char)each));

compared to Smalltalk:

'HelloWorld' do: [:each | Transcript show: each ]

I think this was possible back in 1972 with Smalltalk-72 already.

Smalltalk and Seaside usage in Startups

In 2008 there were some interesting news that a Vancouver-based startup using the Seaside Smalltalk web framework, has been bought by Live Current Media for $5 million. The Smalltalk web application "auctomatic.com" they had built was helping sellers with eBay. I also reported about this in my blog.

According to press the founders of the startup John and Patrick Collision becoming overnight millionaires (as you can also read on the wikipedia page of one of them). Here is a screenshot of the application:

Another nice Smalltalk application that was written in Seaside by a startup was dabbledb.com. It was co-developed by Avy Bryant - original creator of Seaside itself. In 2011 the company was acquired by Twitter and Avy worked for Twitter then. The website of dabbledb.com is meanwhile shut down - but there are some nice videos left on youtube showing the application in action:

Why do I tell you this - as it's nothing new that startups grow up and get successful. A big part of this are always the people behind the scenes - but often key to success is also the technology in use that enables them to meet their goals. And it is not a secret that Seaside and Smalltalk are innovation driving technologies.

Meanwhile the brothers Patrick and John Collison co-founded another company called "stripe.com". The company provides an online payment solution that allow developers to accept credit card payments online using an API. Guess who is working with them: Avy Bryant is also part of the stripe.com team.

What I found interesting is that this week I stumbled upon a Twitter post from John Collision, showing Patrick Collission demoing Pharo Smalltalk (and Seaside) to their stripe engineers.

So it looks like again there is a place for Seaside and Smalltalk (here Pharo) in this new startup. I dont know if it is used for prototyping or directly within their technology stack. But I'm sure both will drive their new business forward as they did in the past...
