  Your Code is My Hell

It occurred to me recently that my experience as a Rails developer may be somewhat unique.I often get brought in to help preexisting Ruby/Rails projects evolve and mature in a sustainable way. As a result, the vast majority of Ruby projects I’ve worked on have been well-established by the time I arrived. In fact, offhand I can only think of one commercial greenfield Ruby project I’ve participated in. All the rest have been “legacy” from my perspective, in the ...

  PHP Security

1. IntroductionWriting PHP applications is pretty easy. Most people grasp the syntax rather quickly and will within short time be able to produce a script that works using tutorials, references, books, and help forum forums like the one we have here at PHP Freaks. The problem is that most people forget one of the most important aspects that one must consider when writing PHP applications. Many beginners forget the security aspect of PHP.

  Why I Hate Android

Why do I hate Android? It’s definitely one of the questions I get asked most often these days. And most of those that don’t ask probably assume it’s because I’m an iPhone guy. People see negative take after negative take about the operating system and label me as “unreasonable” or “biased” or worse. I should probably explain. Believe it or not, I actually don’t hate Android. That is to say, I don’t hate the concept of Androi...

  C++ Versus Objective-C

What will programming in Objective-C mean to the C++ programmer Different Object Oriented Languages Almost all of us have heard the term object oriented programming, and most of us have used C++. How will Apple's purchase of NeXT, and NeXT's framework using Objective-C affect us as we develop software? If we know C++ already, how hard will it be to get up to speed on Objective-C? Many people will agree that once they understand the concepts of object oriented programming it doesn't matter...

  I am a programmer

Admitting that may be career suicide, or possibly it will cost me dearly because 'software engineers' are raking in the big bucks these days, but the fact of the matter is that I'm a programmer. It's what I do best and it is the job title that I associate with most because it feels as though the biggest chunk of me will always be most likely to blurt that out when people ask me what my job is. That I like to program definitely helps.So instead of choosing some fancy title for what it is that I d...

  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...

  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 ?
