Hi, to all those who are doing the the WalkThrough PDF of Cincoms VisualWorks . I already thought I was dumb as I saw that on version 7.5 my version of stripped down helloworld (hello.im) never was stripped down. The solution is simple: VW 7.5 ignores the name of your image and saves the file [...]

Program or not to program?
I have been programming very few things in the past – and rather have worked on existing stuff. I think that this is not a bad attitude if you dont want to fall into the NotInventedHereSyndrom. But I have used a lot of different applications and have also experienced limits of all kinds using this [...]

Some things are different in Smalltalk
In many languages a variable is of some type. Sometimes you have to define the type when you set it or at least when you read it. In Smalltalk you dont redefine the type of a variable. Its always an object. So if you want to work with a value of some type you create [...]

I am not knowledgeable enough to evaluate how good the code is but the [...]

How to start learning Squeak & Smalltalk
There are some recommendations. The most common is to use A Development Example for Squeak 3.9 but I dont like it for a number of reasons: First its overly abstract and secondly it does not show you an overview of the object structure that you should add with it via the system class browser. So [...]

A Little Smalltalk
On my way through Smalltalk I had to make the experience that many tutorials are not uptodate like the freely available PDF “Joy of Smalltalk” where it seems that VisualWorks has changed since this was published. So I could not build my farm
Anyway. Hust out of frustration I have started porting more smalltaks [...]

Squeak built
Here I just like to point to my “Foreseeing Linux” blog and the entry “Squeak packaged for Foresight“. Thats the nice thing about these free software projects: They dont require an installer.

Learning Smalltalk
I have just begun to learn Smalltalk. First: Why? One reason is: Because it has survived! A computer language of that age that is still used in todays projects and also becoming more popular today must be good. Simple.
Another reason is that I heard a lot good about it. Like from Ward Cunningham. I think [...]
