Today we'll take a look at how you can easily store objects in a binary format in external files. VA provides the Swapper framework for this, and it's pretty easy to use. Our example uses a simple point, but you can use theSwapper to store arbitrary objects to a file:
Note the you don't really check for exceptions; that's all done inside the framework. Rather, you check for errors after your code executes. Once you've got the objects on disk, you'll eventually want them back in Smalltalk:
Execute that, and you should see your Point object:

I got home tonight, set up the work laptop and... it failed to boot. Quite often when this kind of thing happens, it's the hard drive (in which case, I would have been off to the local NG shop to get the machine dealt with tomorrow).
Fortunately, you can always look up the diagnostic steps for these things. I found an HP forum with a hard power reset step, and that solved my problem. Which is far better than having to call Texas to make an appointment to visit the IT guys in Linthicum :)

Two of the Collection classes that you might need to know more about are Set and bag. The best way to look at that is via a small example:
What a Bag does is tell you the count for each unique element in the collection. That can be useful if you don't care about the order, but are interested in the occurrences - like this:
Sets give you just the unique elements - useful if you want to filter out duplicates.

I just saw very, very sad news in the Squeak mailing list - Andreas Raab has died. I didn't know him well, but his name pops up all the time in Squeak, and - even after the split - in Pharo. Rest in Peace Andreas - you left us too soon.

Welcome to episode 110 of Independent Misinterpretations - a Smalltalk and dynamic language oriented podcast with James Robertson and David Buck.
This week Dave and I talked about upgrading from one version of Smalltalk to another - I've recently been involved in the upgrading of a large application from VisualWorks 7.6 to VisualWorks 7.9.1 - and one of the biggest lessons here is that it's simpler if you can keep up with the vendor's release cycles. Not always possible, of course.
