Smaller Smalltalk

April 30, 2012 8:21:03.044

The work on a small Pharo Kernel continues:

As said, the PharoCore was great for deployment because it was small. However, Pavel Krivanek was not satisfied, and hence started to work on “KernelImage”. The image is now known as PharoKernel. Such image contains a real small core and it is only about 2 MB. The image has to run headless. Can you imagine Seaside running in 4.6 MB? Just try Seaside on PharoKernel.

Read the rest - they have moved on to using Fuel as a package loader so as to to have a kernel that doesn't even require the compiler.

ST 4U 226: Message Not Understood

April 30, 2012 9:49:46.989

Today's Smalltalk 4 You looks at handling the MessageNotUnderstood exception - by implementing #doesNotUnderstand:. It's a dangerous thing to do, but can sometimes be useful. Today we use a trivial example to demonstrate. 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:

Changes

April 30, 2012 10:23:27.225

Alan Knight is leaving the Cincom Smalltalk team - he just posted in a few of the Smalltalk mailing lists:

I just wanted ot let people on the list know that I've left Cincom and will soon be starting at Google, working on libraries for Dart. I'd like to thank everyone here for their contributions, comments, and discussions over the years. It's been a lot of fun, and I wish everyone here and in the broader Smalltalk and Cincom communities the best in the future. And I'll certainly stay on this list and generally expect to stay active in the Smalltalk community, so in that sense I'm not going anywhere.

I wish Alan every success as he moves over to Google.

ST 4U 227: Launching an External Application in VA Smalltalk

May 2, 2012 10:56:21.079

Today's Smalltalk 4 You looks at launching an external application (a browser in this example) from a VA Smalltalk application. We'll use the composition editor to build our example app. 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:

external app.

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 the Composition editor to hook up a button in a VA Smalltalk application to an external application - in this case, a web browser that defaults to a specific page. To get started, select the external applications folder in the tool, and then use the external application icon. Drop an instance outside the bounds of the window, as we are going to connect a window component (button) to it:

External Application

Double click on the part you just selected to set properties. Use the "find" button to locate the application that will be launched. Note that you can specify a parameter string; here, we'll use an url:

properties

Here we have everything specified:

properties

Now, put a button on the canvas, and connect that to the "start program" aspect of the external application:

connect

If you set it all up correctly, you should see something like this when you use the test functionality and click the button:

test

There's a new Smalltalk group in Vancouver:

The recently created Vancouver Smalltalk developer group organises its first meetup on 16th May. This first edition is the occasion to have a cup of coffee together. We will decide what format we will adopt for the future (coffee shop?, bar?, meeting room?, talk?, subject?)

ST 4U 228: Using OCX Controls in VA Smalltalk

May 4, 2012 10:52:20.699

Today's Smalltalk 4 You looks at changing the font used across the tools 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:

OCX.

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 the Composition editor to embed an OCX control into a VA Smalltalk window. Obviously, this support is limited to Windows. To get started, select the OLE folder in the composition editor, and then use the middle control:

OCX Control

Double click on the part you just selected to set properties. 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

Next, close the properties tool and reopen it. The player will render in the canvas, and its specific properties will become available:

properties

You can specify various control properties; here, we'll set the URL, so that the player opens on some media. In this case, we'll use a podcast mp3 file. Using the test functionality, you can see it work:

playing

Let Them Eat Dialup

May 4, 2012 12:34:46.451

It's not enough that the music and movie industries want to make us suffer through idiotic DRM schemes; they aren't too sure about fast internet at all:

MPAA spokesperson Howard Gantman told Bloomberg that although Google Fiber "could be a great opportunity for consumers whose access to creative content is often hampered by slow speeds," we should look to the example of South Korea, in which "the home entertainment marketplace was decimated by digital piracy," which was enabled by speedy Internet.

What I suppose they really want is a broadcast only internet, where upload speeds are throttled to something that can handle url requests only...

ST 4U 229: Message Construction
