SEARCH KEYWORD -- Collide IDE



  Why, oh WHY, do those #?@! nutheads use vi?


Yes, even if you can't believe it, there are a lot fans of the 30-years-old vi editor (or its more recent, just-15-years-old, best clone & great improvement, vim). No, they are not dinosaurs who don't want to catch up with the times - the community of vi users just keeps growing: myself, I only got started 2 years ago (after over 10 years of being a professional programmer). Friends of mine are converting today. Heck, most vi users were not even born when...

  Why Emacs?


PreludeIf you are a professional writer – i.e., if someone else is getting paid to worry about how your words are formatted and printed – Emacs outshines all other editing software in approximately the same way that the noonday sun does the stars. It is not just bigger and brighter; it simply makes everything else vanish.Neal StephensonIn the Beginning … Was the Command LineI’m an Emacs user and I’m proud of the fact. I know my reasons for using it (and loving it) for many years now. B...

  Comparing Floating Point Numbers, 2012 Edition


We’ve finally reached the point in this series that I’ve been waiting for. In this post I am going to share the most crucial piece of floating-point math knowledge that I have. Here it is:[Floating-point] math is hard.You just won’t believe how vastly, hugely, mind-bogglingly hard it is. I mean, you may think it’s difficult to calculate when trains from Chicago and Los Angeles will collide, but that’s just peanuts to floating-point math.Seriously. Each time I think that I’ve wr...

  Static Code Analysis


The most important thing I have done as a programmer in recent years is to aggressively pursue static code analysis.  Even more valuable than the hundreds of serious bugs I have prevented with it is the change in mindset about the way I view software reliability and code quality.It is important to say right up front that quality isn’t everything, and acknowledging it isn’t some sort of moral failing.  Value is what you are trying to produce, and quality is only one aspect of ...

  The Essence of Google Dart: Building Applications, Snapshots, Isolates


Wіth thousands of programming languages floating around, why is Google introducing Google Dart? What can it possibly add? The short answer: the Google Dart team wanted a language well suited to modern application development, both on the server and the (mobile) client. Some of Dart's features address problems that languages like Java or Javascript have long had. Dart's Snapshots resemble Smalltalk images, allowing (nearly) instant application startup and witho...

  Best “must know” open sources to build the new Web


Here the dump of my ultimate collection of online Web development resources and directory, oriented for the Front-End user Interface (UI). HTML5 and all related open standards are moving fast, but for now, building a whole Website/WebApp on top of that can be very inconsistent, especially across various browsers experiences.   So… how to embrace new awesome web technologies ? Now, as Web Developers and Designers, we have to build on top of more stable framework. It’s here that co...

  Scala feels like EJB 2, and other thoughts


At Devoxx last week I used the phrase "Scala feels like EJB 2 to me". What was on my mind?ScalaFor a number of years on this blog I've been mentioning a desire to write a post about Scala. Writing such a post is not easy, because anyone who has been paying attention to anti-Scala blog posts will know that writing one is a sure fire way of getting flamed. The Scala community is not tolerant of dissent.But ultimately, I felt that it was important for me to speak out and express my opinions. As I s...

  Signs that you're a bad programmer


1. Inability to reason about codeReasoning about code means being able to follow the execution path ("running the program in your head") while knowing what the goal of the code is.SymptomsThe presence of "voodoo code", or code that has no effect on the goal of the program but is diligently maintained anyway (such as initializing variables that are never used, calling functions that are irrelevant to the goal, producing output that is not used, etc.)Executing idempotent functions multiple times (...
