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.

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.

Exhibit A in Why Patents Have Gone Rogue

April 27, 2012 15:04:50.365

It's things like this that make me think we would be better off with no patent or copyright law, compared to what we have now:

A Colorado man says Apple’s smart cover for the new iPad and the iPad 2 violate his 2005 patent for a “Portable Computer Case.”

That doesn't mean that a complete absence of copyrights and patents would be a good thing; it simply means that things are so bad now that a complete free for all would actually be an improvement. What should really be done is a full repeal of copyright and patent law, with a reset to whatever existed after the first set of laws passed at the founding of the Republic....

ST 4U 225: Embedding a Windows Application in VA Smalltalk

April 27, 2012 10:55:18.709

Today's Smalltalk 4 You looks at embedding a standard windows app (WordPad in this case) into a VA Smalltalk window. 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:

OLE.

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 VA OLE support to embed a Windows application into a VA Smalltalk window. We'll use a standard editor - WordPad. To get started, open the VA Organizer, create a new application and part, and add in an OLE client control (To see those steps, refer to this tutorial.

OLE Client

Double click on the client part, scroll down to "clientName", and select one of the available options from the drop down. THe list will vary based on what you have installed on your system; we'll pick WordPad, which should always be available:

client

Next, we'll change decorationPolicy and focusDecorationPolicy to XmNONE - this will remove any application borders, embedding the tool completely into our window:

display

Finally, go to File>>Test, and see the embedding in action:

Skyrim DLC Inbound?

April 27, 2012 0:06:36.025

it looks like the long wait for Skyrim DLC might be ending (at least for those of us with Xboxes):

After a few weeks of teasing, Bethesda may actually announce the downloadable content for Elder Scrolls V: Skyrim soon. Bethesda's PR man Pete Hines said today that more information could be released as early as next week.

Given my work/travel schedule, the new DLC could easily ship while I'm Dallas, leaving me cursing about the exclusive too...

ST 4U 224: Getting Started With OLE Controls in VA Smalltalk

April 25, 2012 10:37:11.856

OLE.

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.

Features

Next, open up the VA Organizer and create a new application and (visual) part:

New Part

That will take you to the composition editor. On the lower left side of the tools section, you should see a new "OLE" category. Select that, and then pick the first (OLE Client) control from the list:

OLE Parts

Right click on the part, and go to settings. Towards the bottom, you should see "sourcePath". We are going to hit the chooser, and select the BMP file to drop in here.

OLE Client

It should render immediately:

OLE Graphic

Finally, go to the File menu and select "Test". You should see your graphic in a new window:

PDF From Pharo

April 25, 2012 8:21:54.647

Need to produce PDF from Pharo? Then you might want to have a look at Artefact:

My project is in progress and many things are not finalized (no documentation, not enough unit tests, etc.). But, you can produce PDF documents with metadata, multiple page formats in a same document, draw tables, write text and paragraphs, play with colors and grey levels.

To load it, try:
