TechEd Europe 2012: typically, we write down requirements somewhere and then use it as the starting point for development. In the talk we see how these two worlds can come closer together: a requirement can be a failing test that development has to fix.

"It is common for a single parent entity to be related to many child entities. This relationship may be required or optional. A  required relationship means that the child cannot exist without a parent, and if the parent is deleted or the relationship between the child and the parent is severed, then the child becomes orphaned.

...we think of requirements of coming in the form of user stories. [...] But what are characteristics of a good story? The acronym "INVEST" can remind you that good stories are...

The Microsoft .NET platform, originally introduced in 2002, is mature and it provides developers with great options for creating software that can meet the requirements of any project.

Addressing this problem, Telerik has assembled its senior technical leaders to produce the Microsoft Platform Guidance 2012. This document attempts to provide prescriptive guidance for .NET developers trying to determine the best .NET technologies to use for specific software challenges.

Imagine if we wanted to display a list of enums within a list, and we actually wanted to have more descriptive values, friendly names if you like, but still maintain the underlying enum value selected where required. This article will show you how to do the following, using WPF.

"Does your company let you work from wherever you want? If it doesn't, it may be watching as progress passes it by. The next generation of working doesn't require a desk."

Big O notation is used in Computer Science to describe the performance or complexity of an algorithm. Big O specifically describes the worst-case scenario, and can be used to describe the execution time required or the space used (e.g. in memory or on disk) by an algorithm. [..] Hopefully this article will help you gain an understanding of the basics of Big O and Logarithms.

"As soon as you have more than a trivial set of tasks you'll need a better system than a simple list and for agile teams, we have Scrum's product backlog."

About Project Euler What is Project Euler? Project Euler is a series of challenging mathematical/computer programming problems that will require more than just mathematical insights to solve.
