Share Counts

I have always struggled with getting all the various share buttons from Facebook, Twitter, Google Plus, Pinterest, etc to align correctly and to not look like a tacky explosion of buttons. Seeing a number of sites rolling their own share buttons with counts, for example The Next Web I decided to look into the various APIs on how to simply return the share count.

If you want to roll up all of these into a single jQuery plugin check out Sharrre

Many of these API calls and methods are undocumented, so anticipate that they will change in the future. Also, if you are planning on rolling these out across a site I would recommend creating a simple endpoint that periodically caches results from all of the APIs so that you are not overloading the services will requests.

Brief history of the "square brackets" as I remember it.

One of the most challenging aspects of the language are the square brackets because they look like arrays, as you just mention.

As I remember the language was inspired in smalltalk, but using C to gain speed.

The idea behind smalltalk was to send message as we do with real life objects. For instance if I ask you your age I would say something like this in natural language:

How to setup your own CA with OpenSSL

For educational reasons I've decided to create my own CA. Here is what I learned.

Вводная часть

У CSS есть несколько базовых проблем, которые позволяют очень быстро отстрелить себе ногу при неправильном использовании:

1. Глобальный неймспейс – в серверном программировании все что написано в файле, в файле и остается. Все же что написано в css и js засирает глобальное пространство имен со всеми вытекающими. В JS эту проблему сейчас побороли всякими модульными системами, а вот с css сложнее. В идеальном мире это должен починить Shadow DOM и настоящие Web Components, но пока их нет единственный способ с этим бороться – следовать какой-то системе именований селекторов, которая по возможности уменьшает и исключает возможные конфликты.

2. Каскадность – если на один элемент может сработать несколько правил, то они все и сработают последовательно. Если есть элемент h1.title, на него сработают все правила для тегов h1 и все правила для класса .title. Так как весь html состоит из тегов, то правил которые п

Using Chrome Traces to Automate Rendering Performance

Ten years ago, increasing the performance of a website usually meant tweaking the server side code to spit out responses faster. Web Performance engineering has come a long way since then. We have discovered patterns and practices that make the (perceived) performance of websites faster for users just by changing the way the front end code is structured, or tweaking the order of elements on a HTML page. Majority of the experiments and knowledge has been around delivering content to the user as fast as possible.

Today, web sites have grown to become complex applications that offer the same fidelity as applications installed on computers. Thus, consumers have also started to compare the user experience of native apps to the web applications. Providing a rich and fluid experience as users navigate web applications has started to play a major role in the success of the web.

Most modern browsers have excellent tools that help measure the runtime performa
