  About HTML semantics and front-end architecture

A collection of thoughts, experiences, ideas that I like, and ideas that I have been experimenting with over the last year. It covers HTML semantics, components and approaches to front-end architecture, class naming patterns, and HTTP compression. We shall not cease from exploration And the end of all our exploring Will be to arrive where we started And know the place for the first time. T.S. Eliot — “Little Gidding” About semantics Semantics is the study of the relationshi...

  Speed Hashing

A given hash uniquely represents a file, or any arbitrary collection of data. At least in theory. This is a 128-bit MD5 hash you're looking at above, so it can represent at most 2128 unique items, or 340 trillion trillion trillion. In reality the usable space is substantially less; you can start seeing significant collisions once you've filled half the space, but half of an impossibly large number is still impossibly large. Back in 2005, I wondered about the difference between a checksum and...

  MySQL Index Merge Optimization Practices

In production environment databases, it is often seen that some SQL where conditions include: equal condition on a normal index + primary key range query + order by limit Although using a normal index would be more efficient, the system chooses to use index merge instead in some cases. This article explores such index merge situations. Index Merge Official Introduction   The Index Merge access method retrieves rows with multiple range scans and merges their results into one.

  The Problem With Client-Side Analytics

Client-side analytics is broken. The numbers produced by it are trivially spoofable by competitors and nefarious characters. Most websites use client-side analytics of one type or another and the only way to get numbers you can trust is to compare numbers from multiple providers and to take an average of the closest two.This post highlights the problem and proposes a partial solution that substantially mitigates the issues with minimal effort. Our proposed solution is simply to include a digital...

  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. Generally, your users are nice people, they will...

  Notes on Programming in C

Introduction       Kernighan and Plauger's The Elements of Programming Style was an important and rightly influential book.  But sometimes I feel its concise rules were taken as a cookbook approach to good style instead of the succinct expression of a philosophy they were meant to be.  If the book claims that variable names should be chosen meaningfully, doesn't it then follow that variables whose names are small essays on their use are even better?  Isn't MaximumV...

  CSS3 Animation With jQuery Fallbacks

In today's post, we'll be taking a look at how you can use CSS3 transitions to power your application's animations with jQuery's .animate() method as a fallback where transitions aren't supported. The benefit of transitions is that unlike JavaScript based animations, they're hardware accelerated in certain browsers and mobile devices, resulting in a potentially smoother overall animation than you would normally experience. In a lot of cases your code will work seamlessly with the solut...

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

WÑ–th 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 wi...

  What is pjax and why we should use it?

What is pjax? Now many websites such as Facebook, Twitter support one browsing style which is when you click one link on their sites, the page will not be redirected, instead only the page contents are updated and URL on address bar is changed. This kind of user experience is much better compared to load the whole page with a blink.
