Modern Justice
So here's where we sit in the US now: Aaron Swartz commits suicide, driven at least in part due to the unrelenting federal prosecution for something the injured party didn't want to pursue. Meanwhile, Dick Gregory gets off on a weapons charge for which DC vigorously prosecutes people without connections. I think it's now fair to say that we live under the rule of connections, rather than the rule of law.

IM 110: Upgrading Smalltalk Applications
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.
You can subscribe to the podcast in iTunes (or any other podcatching software) using this feed directly or in iTunes with this one.
To listen now, you can either download the mp3 edition, or the AAC edition. The AAC edition comes with chapter markers. You can subscribe to either edition of the podcast directly in iTunes; just search for Smalltalk and look in the Podcast results. You can subscribe to the mp3 edition directly using this feed, or the AAC edition using this feed using any podcatching software. You can also download the podcast in ogg format.
If you like the music we use, please visit Josh Woodward's site. We use the song Troublemaker for our intro/outro music. I'm sure he'd appreciate your support!
If you have feedback, send it to jarober@gmail.com - or visit us on Facebook - you can subscribe in iTunes using this iTunes enabled feed.. If you enjoy the podcast, pass the word - we would love to have more people hear about Smalltalk!

RIP Andreas Raab
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.
ST 4U 332: Bags and Sets

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:
| collection c1 | collection := #(1 1 2 3 4 5 6 6 6 7 8 0 9 9). c1 := collection asBag. c1 inspect
Inspecting that gives you this:
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:
c1 occurrencesOf: 9.
That should give you 2.
Now let's try a Set:
| collection c1 | collection := #(1 1 2 3 4 5 6 6 6 7 8 0 9 9). c1 := collection asSet. c1 inspect
Inspect that, and you'll see:
Sets give you just the unique elements - useful if you want to filter out duplicates.
