Welcome to episode 35 of "Thu'umcast" - a podcast where Michael Lucas-Smith, Scott Dirk, Austin Haley, Makahlua and I document our trials and tribulations in Elder Scrolls V: Skyrim
Today, James and Michael talk about playing the game on Expert Difficulty - and Michael explains why you probably should avoid Master. The podcast ends a bit abruptly while we were off on a rant about the gaming industry in general - this was recorded while I was on the road, and the hotel wifi just cut out on us.
If you liked our work on That Podcast, you'll probably like this. We intend to stay with the same idea - a gameplay podcast. If you don't want spoilers, don't listen - we are going to be talking about how we play the game, and what we ran across as we played.

Today's Smalltalk 4 You looks at the a cool - but dangerous - thing in Smalltalk - the ability to handle messages that are not understood. 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:

One of the things you'll run across in Smalltalk is the ability to handle a "Message Not Understood" exception. While there are uses for such handling (proxy development, for example) - it's often quite dangerous. Even more dangerous is implementing a catchall #doesNotUnderstand: message to your class - it can simply swallow all such MNU exceptions, leading to very bizarre behavior. Consider a simple Counter class with a one up counter, and an #addOne (but no #subtractOne) method, and this implementation:
It seems simple enough, but consider the case where that counter is meaningful. A user of the class might think #subtractOne works, and then end up with unexpected values. It can be more serious in a real application - recently, I've been upgrading a VisualWorks 7.6 application to VisualWorks 7.9.1. One of the parts swallowed exceptions like what we have above, and finding the missing methods became very difficult.

We've gone over a basic polymorphism example, but one point needs to be made: when you decide to add polymorphic behavior to your own objects, the API you need to cover is typically small. What if you need to cover a system class - like, say, Collection?
In the simple example we covered here, there was one method to create in each object: #currentValue. If you intend to cover something larger, you'll have more work to do.

Welcome to episode 34 of "Thu'umcast" - a podcast where Michael Lucas-Smith, Scott Dirk, Austin Haley, Makahlua and I document our trials and tribulations in Elder Scrolls V: Skyrim
Today, James and Michael talk about some of the dragon/Nord lore behind the main plot in Skyrim. This came up now that we are both playing the game on Expert difficulty, and Michael has just gotten through Dawnguard. For some of the background we discussed, have a look here.

It's time to get ready for STIC 2013: We are putting out the call for participation for next year's conference. I'm pleased to announce that I'll be helping put together the schedule for this year's talks. This one has some added excitement - we are celebrating the 30th anniversary of Smalltalk.
STIC is a forum where Smalltalk professionals, researchers and enthusiasts can meet and share ideas and experiences. STIC is currently accepting proposals for talks involving Smalltalk technology and other areas of innovation in the software industry. We’re looking forward to an excellent conference and need your participation to maintain the high technical level of the conference!
We are also looking for academic papers for the “Smalltalk Directions” part of the conference. If you plan to submit a paper, please follow the same directions listed below for presentations. Such papers should address possible future directions for Smalltalk and/or Smalltalk-inspired dynamic languages.
The conference will take place at the Wigwam Resort in Phoenix, Arizona on June 9-12, 2013.
Presentations will have 45 minutes time slots including discussion, and they may be in the form of:
History of Smalltalk – It’s the 30th Anniversary of the language, and we would love to see presentations on this topic.
Technical presentations
Experience reports
Technology demonstrations
Panel discussions
Workshops
Describe your idea to us!
Proposals should be submitted by email to Sts_Speakers@stic.st and should include the following information:
Name
Contact information
Type of presentation
A brief abstract
A short biography for the presenter(s)
Any date/time constraints
Any other information you think we should know
If you cannot discuss the internal application you are working on due to corporate restrictions, perhaps you can discuss the application’s component usage or development process. We also plan to reserve time for short presentations in the form of Lightning Talks and short technology demonstrations, but these will be available for sign-up at the conference rather than as advanced proposals. These talks will be limited to a five- to eight-minute time window. So if you intend to volunteer for one at the conference, please be prepared for that!
Submissions should be received by February 28, 2013, and should be submitted either in PDF or Word (Microsoft) format. Note that submissions with incomplete information may be rejected (particularly if a bio or abstract information is missing).
Presenters will qualify for a discounted registration. If your talk is accepted, we’ll have full details on the specifics.
