ST 4U 71: Find that Implementation
Today's Smalltalk 4 You looks at interrupting a Smalltalk function in order to see how it works (and thus be able to customize it in the environment). While we're looking at VisualWorks for the example, the methodology applies across all Smalltalks. If you have trouble viewing it here in the browser, you can also navigate directly to YouTube.

Comcast Giveth and Taketh Away
The new high speed Comcast service - available in my area - sounds interesting. 105 mbps down, and a not terrible 10 mbps up (FIOS gives me better than that up, and while 105 is better than 20, I'm not unhappy with what I have). Here's the killer though: the 250 gb data cap is still on that deal. That may sound like a lot of data, but at that b/w, that's 5 or so hours of HD video. I can totally believe that I'd blow through that much in a month - 3 Netflix rentals might do it.
Why do that? Well, Comcast wants to sell you their triple play (phone/net/tv), and shove you over to on-demand, which won't be capped (but will be charged on a per use basis for all the good stuff). Net Neutrality, you say? Hah - look into the proposals. They all aid and abet this sort of thing with the blessing of law. The net neutrality advocates are today's "useful idiots" as far as the big ISPs are concerned.

Why DRM Sucks
Yet another example in the "What could possibly go wrong" files for DRM:
Thanks to a combination of DRM idiocy and technical and communications failures on the part of EA and Bioware, I (along with thousands of fellow EA/Bioware customers) spent my free time this past weekend needlessly trapped in troubleshooting hell, in a vain attempt to get my single-player game to load. The problem, it turns out, was the Bioware's DRM authorization servers, and as of Tuesday afternoon, the situation still is not resolved. For four days now, those of us who made the mistake of shelling out for Dragon Age:Origins (especially the Ultimate Edition) have been unable to play the single-player game that we paid for. And the unlucky souls who bought the game on Friday haven't yet seen it work properly.
DRM is a fairly complex scheme that makes a number of assumptions about how things should work. If anything breaks down along the way, you just get locked out of stuff you have a legal right to use. In my exercise room, I ended up setting up an ancient PC in order to share a connection with my XBox (the Wifi adaptor for the 360 is priced really stupidly). Why did I do this? Because a few months back, when I was playing ME2, I noticed that the game started demanding a connection in order to authorize DLC (and thus let me play).
THis all leads to very fragile systems, with end customers being on the short, irritated end of the stick. And for what, really? Go google for cracked versions of games, and you'll discover that they are easy enough to find. All DRM does is stand in the way of legitimate users. The people willing to steal are doing that anyway.
I should note that this specific DRM issue was fixed by EA, and DAO apparently works again. That doesn't change the facts though.
CUIS 3.2 Ships
Juan Vuletich has pushed out Cuis 3.2. Some of what's new:
- Enhanced look for menus and several other widgets
- TIFFReader (100% Smalltalk code)
- Many fixes and code enhancements and cleanup, especially in Morphic (World, Canvas, DamageRecorder, etc)
- Text / TextAttribute cleanup

ST 4U 69: Create a New ENVY User
Today's Smalltalk 4 You looks at creating a new ENVY users - just as you shouldn't work as "administrator" on Windows, you really shouldn't work as "Library Supervisor" in VA Smalltalk. If you prefer a written walkthrough to video, then skip down to it. 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:

You can also watch it on YouTube:
When you first set up your ENVY source code repository, there's one user set up - the Library Supervisor. While you could just use that, it's akin to doing everything as the administrator on Windows, or as root on Unix - it works, but carries some risk (the user is simply too powerful). GIven that, it's best to set up a standard user for your regular interactions with ENVY.
As you develop code in VA Smalltalk, everything you do is captured by ENVY - there's basically no chance of you losing code. What we'll look at today is how to set up a new ENVY user for you to use when you aren't administering the repository. First, pull down the "System Menu" on the launcher, as shown below:
You'll be prompted with a small dialog that asks you to fill in three things. Normally, unique name and network name will be the same thing:
Next we'll change users. If you've set up ENVY in the default way, you won't be prompted for a password when you switch users. Pull down the "System" menu again, as shown below, and select "Change User":
You'll see the following dialog come up, with all current ENVY users listed. Select the one you just created, and hit Ok:
That's all there is to it - you can now start creating VA applications, and all of your code will be saved in the repository under this new user instead of under "Library Supervisor". We'll get into using the tools to create applications and deal with other repository uses in future screencasts.

Some StS Video Is Up
Some of the video from Smalltalk Solutions 2011 is up - if you go to the relevant STIC page, there's a list of links. Some of them lead to video, and some of them lead only to the slide decks (although those all say that the video will be forthcoming). You have to click through on each link to tell whether there's video or not; it would be nice if that info were on the index page. The good news is, the video is all hosted on Vimeo, so it'll work on any mobile device you use, not just flash enabled ones.

Where is that Method Defined?
Sometimes you look at a method's declared location and wonder. Take this method in class Text (VisualWorks), for example:
allItalic "Set the emphasis for all characters in the receiver to be italic." self emphasizeAllWith: #italic
Looks like a generic method that should be part of the core aspect of class Text, right? Well, it's not - it's located in package Debugger-Support. This cropped up on us this week, due to the way we do builds now. Instead of RTP stripping, our tool just yanks packages - including Debugger-Support. Whoops. The solution I came up with was to clone the method with a new name in one of our own packages, and change the references in our code (thankfully, only one) to use the new method. This looks like something Cincom should clean up though...
