Anyone planning to be at Oracle OpenWorld? We're looking for Business Analysts who might be interested in participating in a Gamification Focus Group. If you are interested in participating, please contact Gozel Aamoth at [email protected]. We'd love to get folks interested in the topic to participate. There are also a number of other opportunities to give our Applications User Experience team some feedback on designs and concepts outside gamification.

Ok so here is the question: What are the advantages and Disadvantages of Using an Aspect Orientated Programming Paradigm.
My advantages and disadvantages thus far:
Advantages:
Complements object orientation.
Modularizes cross-cutting concerns improving code maintainability and understandability.
Disadvantage:
Not the easiest of concepts to grasp - not as well documented as O-O
O-O goes far enough in the separation of concerns...

Would anyone like to challenge any of these/ add their own?
Many Thanks,

Depuis plusieurs années deux versions majeures d'Eclipse existent: la branche 3.x (historique) et la branche 4.x (précédemment baptisée e4, reposant sur de nombreux nouveaux concepts). En 2012, deux versions ont été publiées: la fondation Eclipse sort Eclipse Juno 3.8 /4.2. Dans la pratique, la version 4.2 est la version officielle, celle qui est mise en avant. Les versions packagées d'Eclipse (EPP builds) proposées sur la page des téléchargements reposent sur la version 4.2.
Pourtant cette migration ...
There is some confusion about durability of data stored in SQL Server in-memory tables, so some review of the concepts is appropriate. The in-memory option is enabled at the database level. Enabling it at the database level only gives you the option to specify the in-memory feature on a table by table basis. No existing tables or new tables will by default become in-memory tables when you enable the feature at the database level. If you choose to make a table an in-memory table, by default it is...(read more)
Once again Jonathan Lewis (Oracle Ace Director, OakTable Network) and Grant Fritchey (Microsoft SQL Server MVP) will host a live discussion on Oracle and SQL Server, this time in relation to temporary tables. Will they agree on some common ground? Or will it be an out and out argument? Either way, be prepared for a lively exchange that will not only entertain, but will teach you key concepts on Oracle and SQL Server.
My team and I are developing an enterprise-level application and I have devised an architecture for it that's best described as an "Expression Tree". The basic idea is that the leaf nodes of the tree are very simple expressions (perhaps simple values or strings). Nodes closer to the trunk will get more and more complex, taking the simpler nodes as their inputs and returning more complex results for their parents.
Looking at it the other way, the application performs some task, and for this it creates a root expression. The root expression divides its input into smaller units and creates child expressions, which when evaluated it can use to build it's own result. The subdividing process continues until the simplest leaf nodes.
There are two very important aspects of this architecture:
It must be possible to manipulate nodes of the tree after it is built. The nodes may be given new input values to work with and any change in result for that node needs to be propagated back up the tree to the root node.
The application must make best use of available processors and ultimately be scalable to other computers in a grid or in the cloud. Nodes in the tree will often be updating concurrently and notifying other interested nodes in the tree when they get a new value.
Unfortunately, I'm not at liberty to discuss my actual application, but to aid understanding a little bit, you might imagine a kind of spreadsheet application being implemented with a similar architecture, where changes to cells in the table are propagated all over the place to other cells that need the result. The spreadsheet could get so massive that applying multi-core multi-computer distributed system to solve it would be of benefit.
I've got my prototype "Expression Engine" working nicely on a single multi-core PC but I've started to run into a few concurrency issues (as expected because I haven't been taking too much care so far) so it's now time to start thinking about migrating the Engine to a more robust library, and that leads to a number of related questions:
Is there any precedent for my "Expression Tree" architecture that I could research?
What programming concepts should I consider. I realise this approach has many similarities to a functional programming style, and I'm already aware of the concepts of using futures and actors. Are there any others?
Are there any languages or libraries that I should study? This question is inspired by my accidental discovery of Scala and the Akka library (which has good support for Actors, Futures, Distributed workloads etc.) and I'm wondering if there is anything else I should be looking at as well?

When thinking about how to learn PHP, many first timers may think of complex theories that are highly technical in nature. Although this is true, you don't need to know the upper level concepts to start learning the basic principles.

This article introduces the essential concepts of the ASP.NET MVC framework, dissects the MVC pattern, and provides real-world examples to illustrate how it works.
Whenever I read a code like this:
struct node
{
int x : 2;
int p : 4;
}n;
with bit fields involved, I get really confused, as to how they are represented in memory, what is sizeof(n) etc., how does it differ with normal members of structures? I tried referring K&R and http://en.wikipedia.org/wiki/Bit_field but they little to remove my confusion. What concepts of bit fields am I failing to grasp?
Ask any proficient search engine optimization (SEO) practitioner, and you will learn that building links to your website is one of most significant methods to use, and also one of the most confusing. For example, you might be told that not all links are equal, and you have to learn about concepts like nofollow, link trust, link density, link popularity, and PageRank (PR). Managing the link profile is not exactly rocket science, but it is not simple either. Here are three main guidelines you can follow.

Due to rather strange circumstances, I only have until Monday to learn (at least) the basics of PHP and .NET programming. I'm already fairly competent (though there is a lot of room for improvement) in C++ so I feel I have some of the concepts nailed already, but I need to get into the two languages in a bit more depth in a very short time frame.
Unfortunately I won't have time to get any books so will need to exclusively use online resources, I'm more of a 'do-er' so any way to test my skills in a practical way would be a huge bonus :-)
