According to Yahoo!'s Exceptional Performance Team, 40% to 60% of Yahoo!'s users have an empty cache experience and about 20% of all page views are done with an empty cache (see this article by Tenni Theurer on the YUIBlog for more information on browser cache usage). This fact outlines the importance of keeping web pages as lightweight as possible. Improving the engineering design of a page or a web application usually yields the biggest savings and that should always be a primary strategy. With the right design in place, there are many secondary strategies for improving performance such as minification of the code, HTTP compression, using CSS sprites, etc. In terms of code minification, the most widely used tools to minify JavaScript code are Douglas Crockford's JSMIN, the Dojo compressor and Dean Edwards' Packer. Each of these tools, however, has drawbacks. JSMIN, for example, does not yield optimal savings (due to its simple algorithm, it must leave many line feed characters in the code in order not to introduce any new bugs). The goal of JavaScript and CSS minification is always to preserve the operational qualities of the code while reducing its overall byte footprint (both in raw terms and after gzipping, as most JavaScript and CSS served from production web servers is gzipped as part of the HTTP protocol). The YUI Compressor is JavaScript minifier designed to be 100% safe and yield a higher compression ratio than most other tools. Tests on the YUI Library have shown savings of over 20% compared to JSMin (becoming 10% after HTTP compression). Starting with version 2.0, the YUI Compressor is also able to compress CSS files by using a port of Isaac Schlueter's regular-expression-based CSS minifier.

Article date 11/03/08 Posted purposely after the triumph. The number of all voters who would reject Obama based on his race, and the number more likely to vote for him because of his race, is about the same. There's apparently more than one reason for a racist to vote for Barack Obama; An abysmal economy during which the white candidate's campaign has seemed disorganized and erratic, common sense or shared values can prevail over gut fears about the color of a candidate's skin. People can look past skin color while acting in their own best interests. For whatever reason or reasons -- the economy, healthcare, the Iraq war, Sarah Palin -- some racists are determined to vote for the black guy over the white one.  Racism will remain an elusive, unquantifiable force, one whose influence we can't tease out from among the many other conflicting factors that will determine how Americans vote.

All website analytical tools have their pros and cons, and many people use more than one to track their website's visitors and gather other important data. With that in mind, I've put together this list of some of the best. All of these web applications offer a free service; while some are completely free, others offer a premium account as well. There is an exception. I've included the Mint and Yahoo analytical software packages in this list due to their popularity, although they are not free.

A 3D-Earth viewer enables navigating through the virtual environment and can be easily downloaded from the internet. How might this rapid development support steady, long-term development of institutions such as Rijkswaterstaat, the roads and water regulatory authority of the Netherlands? The authors consider and compare three standard 3D-Earth viewers: Google Earth, MSN Virtual Earth 3D and NASA's World Wind. Each is combined with Open Geospatial Consortium (OGC) Services to examine their performance in disseminating geo-information to the general public. While Google Earth proves technically superior, other aspects must also be considered.

The unfortunate truth is that the term "community" is now so overly used and utterly misconstrued that it has become meaningless as a way of capturing the true essence of what it really is. It has now become a catch all phrase often used by social media strategists to describe an ideal that doesn't exist. It's become a presumptive description of customers or of end users in whatever form they come in, positioning them as already wanting to connect to a product line or a company. Many in social media end up contributing to this echo chamber, maintaining their standing in online discussions all the while causing damage to the concept as a whole.

Much has been said about Microsoft's Project Natal since its announcement in the 2009 Electronic Entertainment Expo (E3) last June 1. "Natal" was used as the code name of the project because natal means birth and Microsoft considers the latest Xbox 360 video game device as the next generation home entertainment system. It utilizes a motion sensor device that will eliminate the need for a traditional controller and lets the gamer use his full body to interact with the device while gaming.

Accessible data visualization in HTML has always been tricky to achieve, particularly because elements such as images allow only the most basic features for providing textual information to non-visual users. A while back, we wrote an article describing a technique we came up with to use JavaScript to scrape data from an HTML table and generate charts using the HTML 5 Canvas element. The technique is particularly useful because the data for the visualization already exists in the page in structured tabular format, making it accessible to people who browse the web with a screen reader or other assistive technology.

Windows Marketplace plans to launch with 600 applications available for download. While it's an uphill battle to challenge the App Store, this is certainly a great start.

Hewlett-Packard confirmed Tuesday that it is testing Google's Android operating system as a possible alternative to Windows in some of its netbook computers. "Right now Android is barely finished for phones," said Avi Greengart, an analyst at Current Analysis. While it works well enough for T-Mobile's G1 smartphone, the software was released only last year and "the UI still feels half-finished," he said.
