  Getting the most out of your pixels - adapting to view state changes

In Windows 8, your apps run on a variety of screen sizes and under various view states. A user might have your app snapped to the side of a 25-inch desktop monitor, or fill the whole screen of a 10-inch widescreen tablet. In each case, you want your app to take full advantage of the available space. In this post, I show you how you can track the current size and view state of your app in code, and give you tips on how to write your app in the Windows 8 Consumer Preview to handle screen si...

  The mystery of Duqu Framework solved

The Quest for Identification In my previous blogpost about the Duqu Framework, I described one of the biggest remaining mysteries about Duqu – the oddities of the C&C communications module which appears to have been written in a different language than the rest of the Duqu code. As technical experts, we found this question very interesting and puzzling and we wanted to share it with the community. The feedback we received exceeded our wildest expectations. We got more than 200...

  Macro vs. Micro Optimisation

So there's recently been a bit of hype about another Colebourne article: http://blog.joda.org/2011/11/real-life-scala-feedback-from-yammer.html I'd like to respond to a few points he makes. First - You should evaluate Scala and pay attention to its benefits and flaws before adopting it.  Yes, there are flaws to Scala.   Working at typesafe makes you more aware of some of them.  We're actively working to reduce/minimize/get rid of these.   In my opinion, the negat...

  10 Reasons Why Visual Basic is Better Than C#

Visual Basic is a better programming language than Visual C#. Who says so? This article! Here are 10 reasons why you should always choose VB over C#. 1 – “Rose is a rose is a rose is a rose” This is a quotation from Gertrude Stein’s 1922 play Geography and Plays. However, the poetry wouldn’t work in C#, because – unforgivably – it’s a cASe-SeNSitIvE language. This is madness! Before I start ranting, let me just acknowledge that case-sens...

  How Query Optimizer Works in RDBMS

In a previous post, we discussed how the various relational operators are implemented in relational database systems. If you have read that post, you probably still remember that there are a few alternative implementations for every operator. Thus, how should RDBMS determine which algorithm (or implementation) to use? Obviously, to optimize the performance for any query, RDBMS has to select the correct the algorithm based on the query. It would not be desirable to always use the same algori...

  A re-introduction to JavaScript

Introduction Why a re-introduction? Because JavaScript has a reasonable claim to being the world's most misunderstood programming language. While often derided as a toy, beneath its deceptive simplicity lie some powerful language features. 2005 saw the launch of a number of high-profile JavaScript applications, showing that deeper knowledge of this technology is an important skill for any web developer. It's useful to start with an idea of the language's history. JavaScript was created in 1...

  Guest Post from a CodeBoy: The Five Stages of Debugging

Being confronted with a serious and difficult-to-diagnose bug can be one of the most traumatic and stressful experiences of a professional programmer's career. Those who have been through such an ordeal rate the stress as on a par with that accompanying serious injury, divorce, or the death of a family member. Researchers who have studied the psychology of computer programming have lately constructed a framework to understand the stages through which the programmer's mind progresses as she...
