Yesterday I wrote about the support for enclusures that has been introduced with Subtext 2.0. Today I’m going to talk about the improvements we introduced to our skinning engine in order to reduce the number and the size of HTTP requests. And we added support for mobile browsers as well. Web Performance Optimization It all started last year, when Yahoo released YSlow, an add-on for Firebug that measures the performance of a web page based on the best practices evangelized by the Yahoo’s team for Exceptional Performance. Pushed by Mads Kristensen I improved the performances of my own blog with some...

A month ago a popular CSS blog asked: "What is your Javascript library of choice?" Yesterday, after having received more than 1600 answers, he published the results. The winner is clearly jQuery, with more than 50% of the preferences (actually 52%). The second library is MooTools with 15% and third comes Prototype with 12%. As the author of the survey says, the audience of his website is mainly composed by designers, so the results are a bit biased toward jQuery (which has been designed to port the CSS way of thinking into JavaScript development).

What is the Unicode Byte Order Mark (BOM)? Every Unicode string starts with a "zero-width no-break space"; depending on its actual byte representation, a text processor understands the endianness of the characters that follow the BOM. For example, in UTF-16, if the first character of a string is represented as FE FF it means that the bytes in the string are represented using the Big Endian order, while if the string was using the Little Endian order, the first character would have been represented as FF FE. This rule apply only to UFT-16 and UTF-32 encoded strings, and not to UTF-8 (since there is just...

Julien Lecomte is riding the wave of his YUI JavaScript Compressor and has just released the version 2.0 of the YUI Compressor. This version includes Isaac Schlueter’s regular expression based CSS minifier. Therefore now the YUI compressor can minify both JavaScript and CSS files. Minifying CSS will not help me improve my YSlow score again, but will save a few KBytes per request. Technorati tags: YUI Compressor, CSS, Minification

The HTML rendered by some built-in ASP.NET controls is ... ugly: lots of tables, nested tables, useless divs and spans, and sometimes even not compliant with accessibility guidelines for public sites. What is the CSS Adapter ASP.NET 2.0 has the Adaptive Control Adapter Architecture that allows developers to override the default rendering of the built-in controls for some specific browser (for example mobile devices or set-top box). Leveraging this feature, the ASP.NET team released the CSS Adapter Toolkit, which was initially intended as example to show how to develop a control adapter, but then became the de-facto implementation to render some built-in ASP.NET...
