Dr. Geo (aka Dr. Geometry) 12.10 for iPad is available on AppStore. It comes in two versions: gratis and paid.

If you're doing mobile and you want to use Smalltalk, looks like Pharo or Squeak are the way to go.

ST 4U 283: DoesNotUnderstand Abuse

September 14, 2012 0:20:39.299

Today's Smalltalk 4 You looks at how it's easy to use - and abuse - #doesNotUnderstand: in Smalltalk. If you have trouble viewing it here in the browser, you can also navigate directly to YouTube. To watch now, click on the image below:

MNU.

If you have trouble viewing that directly, you can click here to download the video directly. If you need the video in a Windows Media format, then download that here.

You can also watch it on YouTube:


Today we'll look at #doesNotUnderstand: - and how you:

  • Can override it to change the way an object behaves
  • Should never do this lightly - it can create situations where your application fails in very hard to understand ways

First, we'll load the SimpleCounter application we used as an example for WebServices, and add this method:


doesNotUnderstand: aMessage
	| arg dict |
	
	dict := Dictionary new.
	dict at: #one put: 1.
	dict at: #two put: 2.
	dict at: #three put: 3.
	arg := dict at: aMessage selector ifAbsent: [nil].
	arg := arg isNil
		ifTrue: [0]
		ifFalse: [arg].
	self perform: #addValue: with: arg

Notice what this does - it treats a few strings as numeric arguments, and then converts anything it doesn't understand into a send of #addValue: with an argument of zero. That seems great - no more MessageNotUnderstood exceptions here. However, consider a more interesting object doing something like this, and passing values down the chain (maybe to a database, eventually). If you're lucky, you only get bad data. If you're unlucky, you get bad data and very, very odd application behavior.

Note the following workspace code:


counter := Counter new.
counter one.
counter two.
counter three.
counter thousand.
counter goAway


All of that now "works" - or at least, none of those message sends break immediately. However, a follow on developer who sees the sending of #goAway, and looks for an implementor will find 26 nothing. That's the danger here. The code is now much more difficult to understand.

Need more help? There's a screencast for other topics like this which you may want to watch. Questions? Try the "Chat with James" Google gadget over in the sidebar.

Storyboard

September 13, 2012 9:48:49.000

Spotted in PharoCasts

Storyboard is a multi-user agile planning board with drag and drop support. It shows how little code is needed to build a complete application with Deltawerken. It consists of 39 classes, of which 7 are announcements (very simple). It allows you to quickly enter stories, estimate and prioritize them. In addition to stories you can add issue, documentation and chore cards. The cards are colored based on their story state. More details can be entered/viewed by expanding the card. In the expanded view a change history is shown. Other users of Storyboard can be invited to participate.

Twelve Years Ago

September 11, 2012 21:43:21.951

I remember my wife calling me up to the bedroom - I was downstairs getting breakfast - the news was showing the first tower smoking, when bam - the second plane hit. The news anchor thought it was a small plane, but I fly a lot - I knew it was no small plane right off. The rest of the day was spent watching the news coverage, and getting my (then very young) daughter from school. Not that I thought she was in any danger, it's just that every other kid was being picked up, and the school wasn't telling the kids anything. My wife and I called the school, and ended up getting her simply so that she wouldn't keep wondering what the heck was going on. A lot has changed since then, but it's worth remembering where you were and what you were doing when all that went down.

ST 4U 281: Less Common Config Options in VA Smalltalk (2)

September 10, 2012 9:43:06.120

Today's Smalltalk 4 You looks at a few more of the options in workspace preferences, focusing on the export (file out) functionality. If you have trouble viewing it here in the browser, you can also navigate directly to YouTube. To watch now, click on the image below:

export.

If you have trouble viewing that directly, you can click here to download the video directly. If you need the video in a Windows Media format, then download that here.

You can also watch it on YouTube:


Today we'll look at some more of the "hidden" settings in VA Smalltalk - specifically, ones that modify the file out format used by VA Smalltalk. This can be important if you are trying to port code from VA Smalltalk to another Smalltalk, such as Pharo or Squeak. Since Instantiations makes it easy for you to use VA if you are working on an open source project, this might be something that comes up.

Scroll down in the preferences workspace until you find this line:


System genericFormat: false.

Change the false to true, and then execute it:

Workspace Preferences

If you filed out some code before making that change, and then again afterwards, you'll see some small changes in the files:

file out
