Hi guys. It is going to be 4 years since I have started to develop with Squeak/Pharo. In the last months, talking with people or by reading the mailing list, I noticed that I may know some tricks and tips of Pharo that not everybody know. If you are an advanced Pharaoer, you probably won't learn anything new but, if you are a beginner or so, this post may help you.
Today's Smalltalk 4 You looks at the ENVY config map browser - what each part shows, and how you would use the various aspects. 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:

You can also watch it on YouTube:
Today we'll take a brief tour of the Configuration Map browser in VA Smalltalk. For any VA project, it's a tool you'll get very familiar with; it's where you set up all of the loading information for your project. Take a look at the screen capture below:
The list on the left is all of the defined maps in the library. Since your image must be connected to a library to work, this list will grow over time. There are two panes to the right, labeled "Editions and Versions", and "Applications". Any map has a number of versions (anything not versioned will be an open edition - we'll discuss those soon). The list of Applications tells us which Applications make up the config map, and what the load order for them is.
The lower left pane, "Config Expressions" requires some explanation. Generally, you leave this blank, or put in the simple statement "true". However, any Smalltalk expression that answers a boolean could go here. Say you wanted to define a Config Map that should only load on Unix/Linux systems; you might want something like this:
The next pane to the right contains a listing (in order) of any pre-requisite maps - those that need to load before your map can be loaded. One of the nicer things about Envy is that you can edit all of this information without actually loading the map; if you make a mistake that prevents the map from loading, you can some back here and address it.
The last pane on the bottom is for comments - it's often used for license information, or copyright notices. It's free form, and can contain any information you feel is relevant.
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.

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."
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.
