Customer Service, Anyone?

January 8, 2012 17:40:34.000

Best Buy is the latest entrant in the "when sales metrics run the show, everyone loses" sweepstakes:

As a sometime business school professor, I could just imagine the conversation with the TV department manager the day before. “Corporate says we have to work on what’s called up-selling and cross-selling,” the clerk was informed in lieu of actual training on either the products or effective sales. “Whenever you aren’t with a customer, you need to be roaming the floor pushing our deal with CinemaNow. At the end of the day, I want to know how many people you’ve approached.”

This is the sort of thing sales people think is effective. Why, I'm not sure, since nearly everyone I've ever met finds it irritating beyond belief. It sure is a widespread business meme though....

The Podcast Will Likely Be Late

January 8, 2012 10:22:35.541

I'm waiting on one bit of audio, and today is a travel day for me (back to Dallas for the new year). So - the podcast probably won't be posted until later this evening.

Returning to Smalltalk

January 7, 2012 0:35:20.133

Interesting commentary on how Smalltalk "feels" after a long absence, from Noel Rappin. It would be useful if the vendors (and OSS implementations) listened to some of the negatives and thought about them - these are exactly the kinds of roadblocks I recall bringing up more than once when I was at Cincom...

Slamming the Barn Door

January 5, 2012 19:41:30.159

If the movie industry thinks that putting a bigger wait in front of Netflix and Redbox will bring back DVD sales, they are deeply, deeply confused:

A new deal between Time Warner’s movie studio and Netflix, Redbox and Blockbuster will double the “window” for new releases. That means the services will now have to wait 56 days after the discs first go on sale to offer them to their customers, instead of 28 days.

For the most part, movies aren't like music - most of us won't watch most movies more than once. Which means that Netflix or Redbox are the optimum choice. A bought DVD is expensive, takes up space, and is only watched once anyway.

The entire industry desperately needs a clue...

ST 4U 177: Opening Files in VA Smalltalk

January 4, 2012 11:30:05.552

Today's Smalltalk 4 You looks at opening and closing files in VA Smalltalk. 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:

Files.

If you have trouble viewing that directly, you can click here to download the video directly. If you need the video in a Windows Media format, then download that here.

You can also watch it on YouTube:


Today we'll look at opening external files from VA Smalltalk, and how to read/write them once you've done that. To start with, have a look at the application CfsStreams:

CfsStreams

This is where the classes and APIS for reading/writing files are defined in VA Smalltalk. We'll start using CfsReadWriteFileStream to open and write a small file:


"open a file for read/write - if it does not exist, create it"
file := CfsReadWriteFileStream open: 'myNewFile.txt'.
file nextPutAll: 'This is my test text'.
file cr.
file close.

The first line opens the file - after which you can use standard stream methods to read and write text. Here we are simply writing some text, a CR, and then closing the file. The two methods of interest to us here are #open: and #close. The first you send to the class to open the file; the second you always send to close it. Once the file is out there, we can read it, and inspect the results to see what's there:

"open for reading" file := CfsReadFileStream open: 'myNewFile.txt'. data := file upToEnd. file close. ^data.

Read a File

Again, note the use of #open: and #close. Finally, what about error handling? Say a file you want to read doesn't exist? Here's the standard way to check for errors on file handling in VA:


"with error handling"
(file := CfsReadFileStream open: 'someFileNotThere.txt') isCfsError
		ifTrue: [^self error: file message].

All we're doing here is raising an exception on the error; you can, of course, do whatever handling makes sense in that block. Next time we'll get into the Stream APIs that were brushed over here.

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.

ST 4U 176: Exploring Class String

January 2, 2012 12:39:42.341

Today's Smalltalk 4 You starts looking at the basic Smalltalk class libraries in VA Smalltalk, starting with String. 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:

String.

If you have trouble viewing that directly, you can click here to download the video directly. If you need the video in a Windows Media format, then download that here.

You can also watch it on YouTube:


Today we'll start looking at some of the base Smalltalk class libraries in VA Smalltalk, starting with class String. To get started, we want to browse the String hierarchy, in order to get a full picture of the local and inherited APIs:/p>

Browse Hierarchy

Browse Hierarchy

After selecting the launcher pulldown and entering String in the dialog, you should see this:

String

The second pane from the left contains a list of all the applications that define or extend class String. If you look at the status line, you'll see the defining application; you can also find that by scrolling through the list and looking for the application notated with an asterisk. You can see the methods for one application, or select all applications and see the full (at least based on what you have loaded) definition:

Select all Applications

Notice the asterisk in application CLDT, which tells us where class String is defined:

CLDT

Looking at the method categories, you'll see the ANSI-API category, which contains the standard API for the class, as defined in the specification for Smalltalk. Open up a workspace, and you can try some of these messages out:


str := 'James Robertson'.
str asByteArray. 
str asSymbol. 
str at: 3. $m
str copy at: 3 put: $y.
str includes: $J. true
str replaceFrom: 1 to: 3 with: 'jam' startingAt: 1.

Try the second one; you should see this if you display the result:

Testing

Now try the #at:put: message:

Error

one of the changes made to Smalltalk by the ANSI spec was to make Strings read-only objects - that's the exception you are seeing. To do what is being tried here, you need to make a copy first. There's a lot more to explore in Class String - just try experimenting in a Workspace.
