  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 ...

  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 her...

  10 rules of PHP-masters

1. Use PHP only when it is necessary – Rasmus Lerdorf There is no better source than the creator of PHP, to learn what he can do. Rasmus Lerdorf created PHP in 1995. Since then, the language has spread like a wildfire rate in the developer community, incidentally changing the face of the Internet. However, Rasmus did not create PHP with these intentions. PHP was created for the needs of web development. As is the case with many other projects wi...

  Understanding lvalues and rvalues in C and C++

The terms lvalue and rvalue are not something one runs into often in C/C++ programming, but when one does, it’s usually not immediately clear what they mean. The most common place to run into these terms are in compiler error & warning messages. For example, compiling the following with gcc: int foo() {return 2;} int main() { foo() = 2; return 0; } You get: test.c: In function 'main': test.c:8:5: error: lvalue required as left operand of assignment True, this code ...

  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...

  Front-end Style Guides

We all know that feeling: some time after we launch a site, new designers and developers come in and make adjustments. They add styles that don’t fit with the content, use typefaces that make us cringe, or chuck in bloated code. But if we didn’t leave behind any documentation, we can’t really blame them for messing up our hard work. To counter this problem, graphic designers are often commissioned to produce style guides as part of a rebranding project. A style guide ...

  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...

  Taking C Seriously

Dennis Ritchie, a co-creator of Unix and C, passed away a few weeks ago, and was honored with many online tributes this weekend for a Dennis Ritchie Day advocated by Tim O’Reilly.It should hardly be necessary to state the importance of Ritchie’s work. C is the #2 language in use today according to the TIOBE rankings (which, while criticized in some quarters, are at least the best system we currently have for gauging such things). In fact, TIOBE’s pre...
