The worry most people have with this suggestion is that children are going to get discouraged if they fail. But that is not necessarily the case, and I think teachers, parents, and other adults have a great opportunity to help prevent this. If we demonstrate that needing to put down a book for awhile is not a failure, then we can help children become more willing to experiment and to try things which are currently just out of reach.

We want a meaningful class name.

After defining the classes involved in the game design, we now define several states of these classes:

These two overriding methods are more efficient as they avoid unnecessary checks and ifTrue/ifFalse branches. Polymorphism is often used to avoid unnecessary checks and code branches.

There are two kinds of message cascades.

Backticks (`) can be used to create compound literals at compile time. All components of a compound literal must be known when the code is compiled.

  Not to save the image is just best practice advice for you when your primary goal is to create new code. We already discussed the caveats of saving the image concerning code management (See The Image). But from time to time, you’ll find yourself in the position of an explorer when you open multiple code browsers and workplaces to figure something out. In this case, the state of the system, the open windows and code snippets, holds the value you care about, and saving the image is the right way to preserve the system’s state.27

If I give you something that you can play with and extend, even a piece of paper with a paragraph and I say it’s not written well, rewrite it, that’s easier than giving you nothing and say make something; you know, giving a blank sheet of paper and starting to write. So the lovely part that has proven true for professional programmers as well as kids is when you start with something, an object that does something, and then you put many objects like those together and have them interact, and then you extend and make them behave a little differently, you can take a very incremental approach to learning how to control a computer system. — Adele Goldberg

This is another area where the actual mechanics are complex, but the basic ideas are simple.

We think of Morphs and “data objects” as able to present themselves to be inspected, but Smalltalk’s runtime state is also presentable.

  In addition to adding a package preload requirement, you can also select a requirement and delete or update it using the buttons at the lower right. Sometimes a package changes which your code depends on and you have to change your code to accord. When this happens, to want to be sure to require the newer, changed version. Selecting a requirement and pressing update will update the requirement to use the latest loaded package version.

Observe how each category – class or method one – of an extension is prefixed with a *.

Now we are facing a problem. For the need of the TheBook package we extend the Integer class with a method printStringToc, however this method addition is part of the Cuis-Smalltalk core system and its associated default change set.

Let’s say that in our clock morph we want to use color named as in the Color-Extra package. So to be able to load our Morphic-Learning package which makes use of this we need to select our new package and click on the add Requirement button at center, right.

One of the advantages of this media extended plugin is that it can handle more than just YouTube videos. It can handle videos and also some audio notes as well. And I don't think I've tried it with anything else but really I just need YouTube videos.

Modern integrated System On a Chip (SOC) hardware has many circuits which are active at the same time. So one kind of event is sensing something happening in the world. Class EventSensor handles keyboard key press and mouse hardware interrupts, translating between hardware signals and software event objects.

(17 * 13 > 220) ifTrue: [ 'bigger' ] ifFalse: [ 'smaller' ] ⇒ 'bigger' The class Boolean offers a fascinating insight into how much of the Smalltalk language has been pushed into the class library. Boolean is the abstract superclass of the Singleton classes True and False19. Most of the behaviour of Boolean instances can be understood by considering the method ifTrue:ifFalse:, which takes two blocks as arguments: (4 factorial > 20) ifTrue: [ 'bigger' ] ifFalse: [ 'smaller' ] ⇒ 'bigger'

The evaluation of any expression preceded by a ^ (typed as ^) will cause the method to exit at that point, returning the value of that expression.

Dictionary. A dictionary is a list of associations between a key and an object. Of course a key is an object, but it must respond to equality tests. Most of the time, symbols are used as keys.

A perhaps surprising result from the Gilbert paper is that no implementation of an atomic register in an asynchronous network can be available at all times, and consistent only when no messages are lost. This result depends upon the asynchronous network property, the idea being that it is impossible to tell if a message has been dropped and therefore a node cannot wait indefinitely for a response while still maintaining availability, however if it responds too early it might be inconsistent.

However the quorum is only used to detect the failure. In order to actually perform a failover, one of the Sentinels need to be elected leader for the failover and be authorized to proceed. This only happens with the vote of the majority of the Sentinel processes.

Holder is lying to us: even though we instantiate a HolderFactory, the singleton is already initialized, and just sits there in a static field. The performance data for this idiom is unreliable.
