Torsten notes that Method Wrappers have been ported to Squeak:
Eliot ported Method wrappers to Squeak 4.2. If you know VisualWorks you may already know that Method Wrappers can add hidden behavior to a method without recompiling it. It is a very useful package for implementing coverage and tracing tools.
Welcome to episode 24 of "That Podcast: An FNV Diary" - a podcast where Michael Lucas-Smith and I document our trials and tribulations in Fallout: New Vegas.
Today is pretty much the end of the road for "That Podcast" - we wrap up the latest (and last) DLC, "Lonesome Road", and offer a few retrospective ideas on the game. Along the way we mused a bit about where the franchise might go from here. Thanks for listening!
We'll likely have one more (very brief) audio update to announce the particulars for our planned Skyrim podcast. So keep the iTunes subscriptions live, at least for a little while longer.
Got feedback? Send it to James. We'd really appreciate it if you head on over to iTunes and leave a comment - enjoy the podcast, and we'll see you in the wastelands!

lk is like a gun, that "with great power comes great responsibility." Some times, some of the tricks tempt me, and if I know no one's looking (read: I'm not going to be putting this in any production code), I find myself looking around for opportunities to flex a little bit of language super power muscle. Just for the grins. Just because I can.

There is an updated version of Seafox for Seaside, now with an HTML to canvas translator. It's helps you building real Seaside apps from existing HTML templates. You can read more about it here
If you've heard about the Moose project, but haven't been able to wrap your head around it - maybe this video presentation from Doru will help. Hat tip Torsten
Welcome to episode 23 of "That Podcast: An FNV Diary" - a podcast where Michael Lucas-Smith and I document our trials and tribulations in Fallout: New Vegas.
On today's podcast, Michael and James are joined by maki, and guest host Austin Healy, one of our regular listeners. The topic - what else: the last DLC, "Lonesome Road". We cover the entire DLC except for the ending, as - at record time - only Austin had finished the DLC. Next podcast we'll go over the possible outcomes, and likely wrap the entire podcast up. Thanks for listening!

Today's Smalltalk 4 You looks at how you export code from one ENVY repository and import it into another. The context here is moving from one edition of VA to another, but the process is the same regardless of why you need to move code between repositories. You can download the exported repository being used as well. 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:

Today we'll look at how to migrate code out of one ENVY repository and into another one. This can be useful when moving between a personal repository and the "corporate" one, or when upgrading your version of VA. That's the example we'll be working with today - moving the versions of the Seaside Tutorial from VA 8.0.3 to VA 8.5. To start, open up the application editions tool, right click in the listing of applications, and select export:
Once you do that, you'll see a three pane tool. Applications in your repository are on the left. Select one, and all released (not open) editions will display in the second pane. Select the versions you want to export, and move them to the rightmost pane:
Hit Ok, and you'll get a prompt for the ENVY server location. If you are running in a server environment, enter that data. If you are using File IO (as we are in this example), leave it blank, so you'll get a file prompter:
If you left it blank, you'll get a standard file dialog:
Since we are moving the code to VA 8.5, we've selected the image directory for 8.5:
You'll get one prompt we aren't showing here if you aren't exporting to an existing repository, and that's whether the destination repository should be a 1GB max or 16 GB max. It turns out that you are creating a full ENVY repository; the only thing limited is how much stuff we are creating in it to start. Next, Fire up VA Smalltalk 8.5 (or the destination system if it differs), and open up the Application Manager. Select Import from the context menu:
You'll see the same system prompter - either enter the IP of the source system, or, if using File IO (as we are here), leave it blank:
Next you'll see a standard file dialog - select the file you exported from the other VA image:
You should now see the same three pane selector you saw on export - now you need to move applications and editions to the right in order to import them. While our example imports everything, you can be more picky if that's desired:
Now go back to the Application Manager - you'll see as much history as you imported. The imported applications are now ready to be loaded from ENVY.
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.
I see what he's trying to do, and you should read his explanation. I do have some nervousness about how it will be used in application code though. This is the sort of thing that's highly useful in tooling, but often quite scay in application code....

Today's Smalltalk 4 You looks at a build issue you might run into in VisualWorks 7.8 - if you start your build with Store loaded.

Dare Obasanjo makes some great points about how Facebook is "good enough" compared to FourSquare, FriendFeed (etc, etc) - and analogizes what Facebook is doing to the RSS progression:
I’m reminded a little of the world of RSS readers. A few years ago there was a lot of innovation in client RSS readers from commercial offerings like FeedDemon and NewsGator Inbox to home grown projects like RSS Bandit. However, RSS was eventually added to the big gorilla in client communication tools; Outlook. When this happened a lot of the innovation in this space dried up and it didn’t take long for Outlook to become the dominant RSS reader. This is despite the fact that Outlook didn’t go nearly as deep in the RSS reading technology it provided compared to dedicated RSS readers.
That's pretty much how it goes. Lots of people live in Outlook; whatever RSS functionality Outlook provides is, by definition, good enough for those people. Facebook does the same thing to other social media offerings all the time, and so far, it's working.
This week we have another session from ESUG 2010 - Cincom's engineering manager, Alan Knight, talking about the future of Store. Much of that future is in place now, as VW 7.8 shipped with Store migrated on top of the GLORP O/R framework.

Today I was in the last bit of an update from VW 7.6 to VW 7.8 (the last bit of the major work; I'm sure there will be small stuff popping up for weeks yet). The thing I ran into was in my build tool - it just wouldn't build a working runtime. I assumed it was a problem with my script, so I tried RTP to see if things went differently for me (even though I really dislike RTP...). Lo and behold, it failed the same way, but I managed to get an error log (no idea why my build didn't spit one out, but there it is). This method caused me fits, in SystemEventInterest:
notifyStoreBrowser
"StoreRefactoringBrowser has an interest in #earlySystemInstallation. When that event occurs,
it will clear out any open browsers."
Store.Glorp.StoreRefactoringBrowser cleanUpObsoleteInstances
I have no idea why that doesn't have an "isRuntime" check in it - and after speaking to some people at Cincom, I learned that it's probably the eventual answer. In any case, I changed it to look like this:
notifyStoreBrowser
"StoreRefactoringBrowser has an interest in #earlySystemInstallation. When that event occurs,
it will clear out any open browsers."
DeploymentOptionsSystem isRuntime
ifFalse: [Store.Glorp.StoreRefactoringBrowser cleanUpObsoleteInstances].
Which prevents the message from being sent to the (deleted in a runtime) class. It's always something :)
Joachim has some ideas for cleaning up the differences between assert:/should: and deny:/shouldnt: in SUnit. Since the latter messages take blocks (while the former take boolean expressions), he wants to add (or assume it's been added) #value to object and put all of the functionality in the first set of messages.
I recall many a debate over having #value in Object, and I know that it was removed from VisualWorks a few releases ago (although every project I've ever seen has added it back). Joachim's ideas seem reasonable to me; Simpler is usually better.
