Why use Expires header?
Expires header tell the browser whether a resource needs to be requested from the source (server), or if it can be fetched from the browser’s cache. When we set an Expires header for a resource, such as all images, JavaScript files, or CSS, or whatever file we want, the browser will store those resources in its cache. The next time the visitor comes back to the page it will load faster, as the browser will already have those contents available in its cache, and will not need to download them from the server.

I wanted to changed my UI language of Thunderbird and looked for some solution. I got it. However, there is a nice extension to Thunderbird named “Quick Locale Switcher” which allows you to quickly switch to a different language (User Interface, Spell Checker Dictionary and Website content) in your Mozilla application..
Works very well.[……]

I like it:
Being a good developer means compromise. It means sometimes doing things one way for one project, and another way for another. It means balancing the needs of your stakeholders with your ideals. Sometimes they’re not always going to match up, but that doesn’t mean you should stomp the ground with your feet and have a tantrum when things don’t go your way.
The real key? Strong opinions, weakly held.
With that alone, you’ll go far.

Sometimes our network connection is too fast for measure eg. “how my website is loaded”. In that case would be good to slow down our download / upload connection and test our loading website using slower connection. I use NetLimiter – Ultimate Bandwidth Shaper which provide me option for download and upload streaming.
Note: above software is designed only for Windows OS.[……]

Let’s focus on how to move any scripts in WordPress to the bottom of html code. Let’s say we want to move mycode.js file (which is located in /js/ directory in our theme directory) with our code that depend on jQuery in our WordPress theme.

Let’s say you have a localhost (based for example on Wamp) on your computer where is Windows OS. You may be surprised that sometimes some files you can not run. In “error console” of Apache you may see error AH00132 which can look like this:
“[Fri Mar 15 17:44:24.195510 2013] [core:error] [pid 6236:tid 1040] (OS 5) Access denied. : [client 127.0.0.1:51288] AH00132: file permissions deny server access: C:/wamp/www/test/index.html”

By default at least IE up to 9 8 (not tested on IE10 IE 9 and 10 doesn’t block loading content and they use local fonts, if available) blocks loading page until fonts are not downloaded. Moving fonts for font-face to separate subdomain (eg. fonts.example.com) means that page loading will not be blocked by loading fonts from font-face. However, you may discover that fonts are not loaded after moving them to separate subdomain. What is wrong?
You must add header Access-Control-Allow-Origin "*" (or specify here your subdomain) when serve fonts[……]

So, you want to detect browser cookie third party support.
What is third-party cookies
Basically, third-party cookies are cookies that are set by a website other than the one you are currently on. For example, ctomczyk.pl might have a Twitter like button. That button will set a cookie that can be read by Twitter. That would be considered a third-party cookie.
Some browsers (from specific versions), like Firefox and Safari, have this option disabled by default. However, see page “How to enable third-party cookies in your web browser” t[……]

Tried to run internationalization in WAMP using php_intl module, but got error Unable to load dynamic library ‘c:/wamp/bin/php/php5.3.13/ext/php_intl.dll’. This makes me headache. It happens because Apache can’t find the icu*.dll files. There is at least 3 solutions:
- One solution is to add “C:\wamp\bin\php\php5.3.9” (or similar directory) to your system PATH.
- The other solution is to copy the icu*.dll files to your apache’s bin directory.
- A third option is to copy the icu*.dll files to your Windows system directory (system32 or SysWOW64)[……]
