Twitter is down, but that's not what I'm posting about. What's awesome is the error message I got in Firefox:
Twitter is currently down for <%= reason %>.
We expect to be back in <%= deadline %>. For more information, check out Twitter Status. Thanks for your patience!

There's a new version (6.2.1) of Smalltalk/X out - you can download it now. It's a pretty open system:
Smalltalk/X may be used even for the development of commercial Software and Applications without any licence fee (a few minor restrictions apply [*]). We appreciate your interest in Smalltalk and only ask in reply for you to share your joy and experience with others and help us marketing the great Smalltalk ideas ;-). In addition, it would be nice if you share example programs, demos, improvements, add-ons and national language translations with others by publishing those or send them to us for integration into the next release
You'll have to visit the website for those restrictions; the link is a Javascript popup.

Sometimes you need to move one or more classes from one Application to another (in ENVY). It's fairly easy to do, but there are a few things to keep in mind. To set up, we've created three applications. In the first one, we defined a class. In the second, we extended that class (with a new method). In the third, we defined another new class:
Before we can move a class between applications, we need to open the editions (both source and destination). In the example here, all three applications have been released; we'll create open editions first:
In the second image above, all the applications to which we could move the class are listed. Notice that MyApplication2 is not listed? It's open, but it extends the class in question. Given that setup, we cannot move the class into MyApplication2. We can move it into MyApplication3, because it's open, and has no extensions that get in the way.
Why isn't anything else listed? That's simple - we didn't create an open edition on anything else - thus, they are all ineligible to be recipients of the move. ENVY only shows us the possible destinations.
Now, select the class in MyApplication3, and try to move that. You'll see the following options:
Finally, try moving the extension in MyAplication2:
That can be moved to MyApplication1, where it would simply join the rest of the class. If we do that, the browser will look like this:
As with any changes made in an open edition, VA highlights them for us.

Yes, it's gotten to the point that I now believe patents are - on balance - a bad thing. Check out this stupidity: a patent troll claiming the right to shutdown Mojang based on a client/server license check.

Today we'll continue with inspectors in VA Smalltalk. One thing to bear in mind is that you are inspecting the live object - try inspecting the code below:
1 to: 100 by: 20.
You should see an inspector on the Interval object. The instance variables are on the left, with the values on the right. For self, we see a printable representation of the entire object:
Now, on the left, select by, and change the value to something else - like 11. Pop up the menu in the right pane, and select save:
You can do that for any object in the system, but be careful - if you were to inspect something like CwConstants, which is used across the system, and make changes, you could damage the way things operate. With Smalltalk, you have a lot of power, but you need to be careful about how you wield it.
