I'll be on vacation next week, so there won't be any new Smalltalk Daily screencasts until a week from Monday. In the meantime, just check the archives, and feel free to send me suggestions for things you would like to see covered!

If you're a member of the ACM, then you now have access to the 2009 Proceedings of the International Workshop on Smalltalk Technologies.

I got a query about Smalltalk code to handle RSS/Atom feeds this afternoon, and - obviously, as the main author of BottomFeeder - I have some code around to do that. In the public store repository, you can load the bundle Syndication-Handling. I've done a screencast on using it:

And on YouTube:

RSS.Constructors.Constructor 
	getFeedFromUrl: 'http://www.jarober.com/rss/blog.xml'.

Dave Buck just published a useful little tool to the public store repository.

I've published a package called FindAgain to the Cincom public Store repository. It allows you to search for senders of a selector or references to a class or shared variable (which you could do before) and when you select one, find subsequent references to that selector or variable in the method (which you couldn't do before).

Spotted in Planet Squeak:

The frustrating part is not using many images (which is pretty cool to have multiple computers running at once… but I digress), but setting up the images every time.  So I decided I’d find a way to load common configurations automatically.  But how would I communicate to the image that it should run certain code on startup?  A quick google found writing scripts.

This is one of the nice things we did to Cincom Smalltalk over the last few releases; made this kind of scripting a whole lot easier. In fact, if you check this Smalltalk Daily archive page, you'll find some nice examples. For a more general overview, I covered all of the command line arguments - for both images and the VM - here.
