Roles: Composable Units of Object Behavior

Roles: Composable Units of Object Behavior: "A significant new part of Perl 6’s object model and type system is the addition of roles. Part of their origin is an implementation in Smalltalk (there called traits). They also solve some systemic problems of other OO systems. Why are they useful and how do they work? What is a Role? A role is a named collection of behavior — a set of methods identified by a unique name. This resembles a class or a type, in that referring to the role refers to the combined set of behaviors, but it is more general than a class and more concrete than a type. Put another way, a role is an assertion about a set of capabilities. For example, a Doglike role identifies the important behavior that any doglike entity will possess: perhaps a tail attribute and the methods wag() and bark(). Even only this much is a great advantage to using roles. Presuming you have a method that needs something Doglike, you can ask “Does the class or object I receive behave in a"

Google's Master Plan: "Maybe we should stop trying to guess the next Google services. What's next for Google is right here on a big whiteboard from their GooglePlex. The photo was taken last year by Niall Kennedy and includes a small part from their master plan. As you can see many projects that don't have a tick in the whiteboard have been launched.A bigger and more comprehensive image is available here, but it's not very clear.As you can see, there are a lot of verticals and new domains: travel, health, TV, games, reviews, marketplace, dating, real estate, jobs, mortgage, pets, music and many ambitious projects like redesigning TCP/IP, and HTTP and creating a new generation of web based on BitTorrent.Other pieces from the puzzle (half jokes, half serious projects): "

[copied from IBM blog] A new company enters the enterprise mashup space

A new company enters the enterprise mashup space: "Dion Hinchcliffe asserts in this post that enterprise mashups are becoming increasingly important to IT organizations and the business they support. However tools to enable the creation of enterprise mashups are few and far between. In fact, while he notes 'Not sure about any of this? IBM has clearly identified mashups as a key enterprise trend as well', he only cites one tool that meets all his criteria: 'However, I've recently come across one product that clearly shows almost the full potential of enterprise mashups in a single package, despite a few rough edges. Datamashups.comI recently came across Applibase's impressive DataMashups.com site, and more than any other product I've seen so far, it clearly demonstrates the possibilities and potential of enterprise mashups guided by end-users and shared amongst co-workers. The site has an excellent service preview that lets you quickly start assembling mashups visually, right online, using a rich palette of pre-existing widgets, feeds, data from local and remote SQL database"

[originally at chiefhappinessofficer] Get lucky at work - be positive

Get lucky at work - be positive: "My driving force in business has always been enthusiasm. I’m easily amazed and get curious and fired up about many different things. In fact, I refuse to work on anything that does not grab me in that way. I remember one meeting I had with a woman who was… let’s say slightly less positive. At one point in the meeting, she said “You’re very positive, arent you?” I had to agree, that that was indeed so. It was only after the meeting that I realized that she’d meant it as criticism :o) Positivity has been getting a bad rap at work. If you’re too positive you can be accused of being pollyannaish, uncritical, unrealistic, silly, etc… “Well,” some people say, “it’s all very good for you to be so optimistic but some of us have to work in the real world.” And while there are many great reasons to be more positive at work, there’s one I’d like to mention specifically: Being positive at w"

Ease the integration of Ajax and Java EE: "Patrick Gan has written an article for IBM-Developerworks that provides an overview of how Ajax can be integrated into a Java EE Web application. Part of the integration is trying to reconcile the differences in the communication models used by Java EE and Ajax.
