High Performance Web Sites: Essential Knowledge for Front-End Engineers Review§
_High Performance Web Sites_ is one of those books that will get read by more people than buy it because it is both a fast read and organized into clearly differentiated subjects. This makes it easy to pick up for a moment or pass along to team members with different specialties.
Each of these "14 Steps to Faster-Loading Web Sites" (listed in the editorial review above) is itself divided into related tips with practical pointers. The fact that the book is full of these pointers is not the only value I extracted. We also get something a bit more subtle. The fact that the author is a performance expert at one of the mega-companies that define the Web for most of us lends authority to the book. It is easy to have confidence that his practical experience will have immediate lessons for teams with the same problems, if on a smaller scale.
Steve Souders provides a special addition to his tips: his example pages offer direct comparisons and means to make our own tests. This is something rarely encountered in such books. The book ends with a 30-page chapter where he deconstructs 10 of the top Web sites in the U.S. using the rules and tools described in the book.
§High Performance Web Sites: Essential Knowledge for Front-End Engineers Overview
Want your web site to display more quickly? This book presents 14 specific rules that will cut 25% to 50% off response time when users request a page. Author Steve Souders, in his job as Chief Performance Yahoo!, collected these best practices while optimizing some of the most-visited pages on the Web. Even sites that had already been highly optimized, such as Yahoo! Search and the Yahoo! Front Page, were able to benefit from these surprisingly simple performance guidelines.

The rules in High Performance Web Sites explain how you can optimize the performance of the Ajax, CSS, JavaScript, Flash, and images that you've already built into your site -- adjustments that are critical for any rich web application. Other sources of information pay a lot of attention to tuning web servers, databases, and hardware, but the bulk of display time is taken up on the browser side and by the communication between server and browser. High Performance Web Sites covers every aspect of that process.

Each performance rule is supported by specific examples, and code snippets are available on the book's companion web site. The rules include how to:

Make Fewer HTTP Requests
Use a Content Delivery Network
Add an Expires Header
Gzip Components
Put Stylesheets at the Top
Put Scripts at the Bottom
Avoid CSS Expressions
Make JavaScript and CSS External
Reduce DNS Lookups
Minify JavaScript
Avoid Redirects
Remove Duplicates Scripts
Configure ETags
Make Ajax Cacheable

If you're building pages for high traffic destinations and want to optimize the experience of users visiting your site, this book is indispensable.

"If everyone would implement just 20% of Steve's guidelines, the Web would be a dramatically better place. Between this book and Steve's YSlow extension, there's really no excuse for having a sluggish web site anymore."

-Joe Hewitt, Developer of Firebug debugger and Mozilla's DOM Inspector

"Steve Souders has done a fantastic job of distilling a massive, semi-arcane art down to a set of concise, actionable, pragmatic engineering steps that will change the world of web performance."

-Eric Lawrence, Developer of the Fiddler Web Debugger, Microsoft Corporation

USB Cordless/VoIP Phone Support MSN Yahoo Messenger ReviewBeen using Skype on my Windows 7 (64 bit) laptop quite happily for a few months now. My only concern after those months was being physically 'tied to the computer' to be able to 'use my phone' (Skype is my only telephone service of any kind) So the search for a cordless phone began. This 3J-W1D cordless Skype USB phone fills my needs 100%. The included software installed effortlessly and afterwards a system reboot got Skype and SkypeMate (the phone's software client)in sync and I was immediately able to call people from wherever in my home I desired. I need to clarify an erroneous review here. This phone DOES come with a battery that is shipped inside the same packing sleeve the phone comes in but not obviously so. Hence I suspect the other reviewer probably threw his battery out with the rest of the packaging. Anyway if you look closely it is impossible NOT to see the battery tucked in it's own little cardboard 'doghouse' formed within the phone's own cardboard packing sleeve. The batery is white and only about the size of 2 USA first class postage stamps placed side-by-side. It thickness is about a 1/4" at the moct. The attached wiring (which one needs to plug into the phone) is so very tiny. My fat 59 yr old fingers were able to do it. I suggest you enlist the help of a child to avoid stress and swear words! Anyway the phone works fine it duplicates the contacts list from your pc-based Skype program. I have yet to test the advertised 160 ft range but since it is adequate for me at home (about 50 ft max)I am pleased. Maybe some sunny morning (or starry night) I'll stroll out onto the veranda and call someone. BTW here is a link to the owner's manual (pdf) should you like to see that pre-sale. [...]The phone is entirely powered from any available USB port. My battery was partially charged when I installed it and I was able to make some calls to test it for any issues. Once I placed it on the base (which includes a nice sounding speaker phone)it indicated it was charging for abour 3 hours (flashing led) then finally fully charged (steady led). The handset display is black and white with a very nice 'blue glow' background lighting. I find it easily readable and quite attractive too. One pleasant surprise is the feel of the phone in your hand. It is about 3/4 scale size of a 'normal' landline cordless phone but the tactile response (what it feels like to the touch) is a smooth yet gently 'grippy' somewhat soft rubber-like texture. It feels great and is not likely to slip out of your hands easily.
My only complaint is i have yet to see how to change the 24 hr format time to 12 hr am/pm format. It seems to mimick the installed Skype pc software which I don't think has an option or a Skype 'Extra' for this selection. I sent an email to the manufacturer in Gilbert,AZ about this but so far no replie. (How many times have we read similar words ..eh?) Here is the homepage for this phone's manufacturer [...] Lastly while on it's base the time is easily readable in about 3/4" high bold black letters and beneath that in smaller text it says "Let's Skype" so it makes for a handy clock too depending where you place it and that is what led me to wanting to set it from 24 hr format to 12 hr am/pm. Right now it is 1:04 pm but my Skype phone says it is 13:04 and makes me feel I'm back in the Army again.
I would HIGHLY recommend anyone looking for a realtively inexpensive Skype-based cordless USB-powered phone to try this one out. Bought mine from Amazon through the $2.99 overnight shipping Amazon Prime account (30 day free trial is well worth it..hehe!)
BUY THIS PHONE!!!

USB 2.4ghz 50 Meters Wirefree Usb Cordless Skype Phone ReviewThis is an *AWESOME* phone! I've had this unit since August 2007, and has been working eversince with no issues! The battery life is exceptional with talk time averaging about 5-6 hours depending on how often i've used it. The past reviewers of this product apparently, did not know how to program it properly. And i do agree, however, that the instructions are poorly written. But i did do a little more research on Skype and you'll need to install the current Skypemate firmware to make the unit fully operational as advertised. The following links are the download page where you can download the Skypemate firmware for *FREE*-
for XP / Vista users head to the following link: [...]
