XML Browser with Pharo

I've written a little tool to help me browse xml. If you want to try it:

Gofer new
 squeaksource: 'LaurentLSandbox';
 package: 'XML-GUI';
 load.
 
((Smalltalk at:#XMLBrowser) labelled: 'Picasa search')
  browseAtUrl: 
   'http://picasaweb.google.com/data/feed/api/all?q=lighthouse&max-results=10'.

See XMLBrowser comment for examples.

FizzBuzz Kata: minimal solution

Trying to find a minimal solution for the FizzBuzz Kata in Smalltalk:

fb := [:counter| |rules|
       rules := {15->'FizzBuzz'. 5->'Buzz'. 3->'Fizz'. 1->counter}.
       rightRule := rules detect: [:aRule| counter \\ aRule key == 0].
       rightRule value].  

self assert: (fb value: 7) == 7.
self assert: (fb value: 3) == 'Fizz'.
self assert: (fb value: 5) == 'Buzz'.
self assert: (fb value: 15) == 'FizzBuzz'.

1 to: 100 do: [:counter | 
               Transcript 
                 show: (fb value: counter) asString;
                 cr]

Update: Little variant from Alexandre:

rightRule := rules detect: [:aRule| counter isDivisibleBy: aRule key]

Smalltalk tiny exercise for TDD newbies

Done in course:

Create the category Exercise in the Browser. All classes you create will be placed in this category.

Implement the class Operation (using Test-Driven Development) which should work like this:

1. a := Operation new.
   a result.
   

   Should return 0.

2. b := Operation new.
   b add: 2.
   b add: 3.
   b result.
   

   Should return 5.

3. Operation new
     add: 2;
     add: 4;
     divideBy: 2;
     result.
   

   Should return 3.

Add the message Operation>>#multiplyBy by yourself.

Why technology matters

Life is very short. You have a limited amount of time in which to realize your dreams, in which to do your projects. If you’re like me, you probably have dozens and dozens of ideas for apps, sites, portals, that you want to implement. Most of those ideas will suck. But you don’t know which ones, you won’t know until you try them. Your goal, in this life, is to iterate faster. To fail more, to fail quicker, until you get to the brilliant ideas and brilliant projects that can change the world, or at least make you a dollar or two.
