Memoization for Smalltalk

May 15, 2012 13:47:30.000

Travis talks sorting n VisualWorks:

The core default sort algorithm in VisualWorks is hybridization of quicksort and a insertion sort. The implications for this, is that this somewhat expensive toolListDisplayString method may be called repeatedly for some objects. That means redundant CPU cycles. A common solution to this kind of problem is memoization. Memoization basically is a fancy word which means "cache the results of your computation function, so you only evaluate the function once for each unique input and just look up the cached result for subsequent calls."

Smalltalk and Fluentd

May 15, 2012 9:47:45.000

There's another logging framework available for Smalltalk, but this one isn't standalone - it's an interface to Fluentd:

Nagare is designed to be simple and scalable. Contrary to other logging frameworks which provide rich set of log output methods (file, socket, DB, etc.), Nagare just connects to fluentd (http://fluentd.org). And Fluentd does the various log processing jobs.

ST 4U 231: Code Completion in VA 8.5.1

May 11, 2012 9:13:01.185

Today's Smalltalk 4 You looks at the upgrades to code completion in VA Smalltalk 8.5.1. 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:

Code Completion.

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 go back to code completion in VA Smalltalk - there have been a lot of improvements in the 8.5.1 release. When the video from STIC 2012 is released (check the conference pages regularly), you should definitely watch it. In the meantime, let's open up a workspace and have a look. Notice that we've defined our variables as temps; the code completion support relies on having a valid compilation environment. If you don't have that, you won't see suggestions:

Code Completion

One of the niftier new things is camel case support. Try typing in RWS - you should see suggestions immediately, although you can always hit ctrl-space to get them:

camel case

The new support is smart enough to split on the case changes, and match RWS to ReadWriteStream. What's really nice is that it also works for keyword messages, splitting both on case and colons. Try creating an OrderedCollection and then entering aai:

camel case

Notice that it matched for messages in the collection hierarchy - the support takes note of the compilation environment, and uses it to give you better answers.

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.

Minor League Football?

The USFL is back, and it looks like they intend to run it as a minor league. Maybe if it takes off, colleges could get away from football and back to, you know, academics....

ST 4U 230: Using OCX Controls in WindowBuilder

May 9, 2012 8:05:40.384

Today's Smalltalk 4 You looks at utilizing OCX controls in WindowBuilder Pro (VA Smalltalk) - we've already looked at using them via the Composition Editor. 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:

OCX in WB Pro.

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 use WindowBuilder Pro to embed an OCX control into a VA Smalltalk window. Obviously, this support is limited to Windows. To get started, select the OLE controls in the palette, and then select the control:

OCX Control

Double click on the widget to bring up properties; it might take a moment, depending on what you have installed. In clientName, select the control you want to use - the list will vary based on what you have installed on your windows machine. Here, we've selected the Windows Media Player:

windows media

To see it work, put in an url for playable media (Video or audio):

properties

Unlike the composition editor, the embedded player starts operating on what you entered immediately. You can also test it:
