The following is an in-depth demo showcasing the new features of the new dynaTrace AJAX Edition, as well as the deep diagnostics that made the original dynaTrace AJAX so popular.
So, now that we know how things are performing let’s see how well optimized the pages are. We’re going to look at what I consider to be the most critical optimizations (until you have implemented all of these you shouldn’t be looking at anything else and there is no reason in this day and age that sites shouldn’t be doing these).
A wiki to collect information on this topic as there are a lot of presentations written about it but all differ in approach and content and collating all these great ideas can help us form a solid approach to selling web standards to the business.
a module for the Apache HTTP Server called mod_pagespeed to perform many speed optimizations automatically. We’re starting with more than 15 on-the-fly optimizations that address various aspects of web performance, including optimizing caching, minimizing client-server round trips and minimizing payload size. We’ve seen mod_pagespeed speed up websites by about 2x, and sometimes even faster.
Fake is a new browser for Mac OS X that makes web automation simple. Fake allows you to drag discrete browser Actions into a graphical Workflow that can be run again and again without human interaction. The Fake Workflows you create can be saved, reopened, and shared. Power Users will love Fake for automating tedious web tasks like filling out lengthy forms and capturing screenshots.
Internet Explorer 8 introduces compatibility modes which gives a way to introduce new features and stricter compliance to standards while enabling it to be backward compliant. In this post I would like to discuss how compatibility mode can be specified and how IE determines which mode to use in different scenarios.
Official UI and UX guidelines from the manufacturers. Here, you will find guidelines, samples, tips, and descriptions of common mistakes. Many of the guidelines focus on native app development, but we can apply most parts of them to mobile web design. Remember to provide the best possible experience on each platform. Each platform has its own UI and usability guidelines that users expect.
You’ve probably seen a QR code before, even if you didn’t know what it was. It’s a little square matrix barcode that can be read by either a specialized scanner or a cellphone with the right software. A QR code can contain any sort of textual information, which will be decoded by a QR reader. A web address, a simple message, a phone number, etc. Google has a nifty API for generating QR codes
Pretty self-explanatory, definitely worth checking out!
It’s been nearly two years since I wrote about using Google’s CDN to host jQuery on your public-facing sites. Though the post has been overwhelmingly well-received, concerns have been raised. So, I decided to cobble together an HTTP crawler, analyze 200,000 of the most popular sites on the Internet, and determine how many of those are referencing jQuery on Google’s public CDN.
