  40+ Techniques to enhance your php code

1. Do not use relative paths , instead define a ROOT path Its quite common to see such lines : 1require_once('../../lib/some_class.php'); This approach has many drawbacks : It first searches for directories specified in the include paths of php , then looks from the current directory. So many directories are checked. When a script is included by another script in a different directory , its base directory changes to that of the including script. Another issue , is that when a script is being ru...

  JavaScript Attack/Defend

As developers and designers we work hard to build visually attractive, fast and easy to maintain applications. Our goals are to make sure the applications we build stick to users and keep them coming back for more. Security is not always at the forefront of our minds. No one intentionally builds insecure software but often a lack of security knowledge leads developers to build vulnerabilities into their applications. In this article we are going to examine two web security attacks, how they are ...

  Lessons Learned while Introducing a New Programming Language

I've used a lot of languages (professionally) over the years: (off the top of my head) Cold Fusion, HTML, Javascript, php, SQL, CSS, ASP(classic & .net), C#, Ruby, Flex, Java, & Clojure. Each language has pros and cons. Being a programmer, it's easiest to discuss the cons - and in general I believe it was best said:I hate all programming languages - Matt FoemmelI think it's important to start with this in mind. At some point you're going to hate what you're advocating, so imagine h...

  Image lazy loading plugins on Github

Image lazy loading is a concept where images are getting loaded only when needed. It has been adopted in many web applications to reduce usage of bandwidth. When a web page is loaded in a web browser, not all the page elements would be visible in the view port, hence those resources(images, videos etc) don't need to be loaded.  Currently there are quite a few open source plugins on Github which can help achieve image lazy loading. Today we will introduce a few of them. Echo.js Echo.js is a ...

  How One Missing `var` Ruined our Launch

Well, that was a veritable shitstorm (sorry for the language).  Long story short, MelonCard was featured today on TechCrunch (along with other500Startups companies, also on VentureBeat, Forbes, …) and everything broke all at once.  Every. little. thing.  We had rolled out a huge change to MelonCard over the last few days to make our site a seamless “everything just updates” look-good / feel-good product using NodeJS lo...

  The 15 Golden Rules of UI design and flow.

Last night a good friend of mine showed me the latest Need for Speed game on the iphone / ipad. Quite an impressive feat of rendering and a relatively good game to boot. However, the front end, wow, a classic case in UI mis-engineering. Loads of stats, pages and pages of bits and pieces to wade through – a classic case of over stimulating the player with lots of decisions they have no business making – stuff that will significantly change their game play experience but being...

  Performance is a Feature

We've always put a heavy emphasis on performance at Stack Overflow and Stack Exchange. Not just because we're performance wonks (guilty!), but because we think speed is a competitive advantage. There's plenty of experimental data proving that the slower your website loads and displays, the less people will use it. [Google found that] the page with 10 results took 0.4 seconds to generate. The page with 30 results took 0.9 seconds. Half a second delay caused a 20% drop in traffic. Half a seco...
