Google's SPDY protocol will speed up the web - and Chrome OS, too

Over at the Chromium blog, Google has announced a project they've been working on called 'SPeeDY.' It's an updated transport protocol for the web which improves upon HTTP, reducing latency through network-fu like multiplexed streams, request prioritization, and header compression.

"We started working on SPDY while exploring ways to optimize the way browsers and servers communicate," says the official blog post. It continues, "We want to continue building on the web's tradition of experimentation and optimization, to further support the evolution of websites and browsers."

It's not all about altruism, of course. Improvements like those Google is seeking with SPDY, the Go! programming language, and Native Client will all greatly benefit the Chrome browser and Chrome OS. After all, an OS which relies heavily on the cloud for access apps and data will certainly perform better with an improved protocol powering the client and server. It's probably a safe bet that Google would roll SPDY on their own servers early on to give apps like Google Docs and Picasa Web a performance boost on the Google platform.

Whatever the motivation, I'm all for more speed on the web. My ISP is obviously in no hurry to improve things on that front, so if Google can pull off the estimated 55% performance gain then I'm all for it. You go, Google!

Web inventor: Sorry about the //

//
You know how pretty much every web address starts with http:// or https:// or something similar? After the first few hundred times you probably stopped thinking about it. And most modern web browsers don't even require you to type it at all. But if you add up all the seconds people have spent typing http://, you'd probably have a lot of seconds on your hands. And it turns out, there's no really good reason for it.

Tim Berners-Lee pretty much created the World Wide Web as we know it. And looking back, he says that while the "http" part of a URL makes sense, there's no particularly good reason for typing the double-slashes.

While Berners-Lee laments that many trees and work-hours could have been saved if he had left out the unnecessary // marks, I'm guessing that nobody was really all that hurt by their presence. But I guess it does show that in hindsight, pretty much anything could be done better.

HTTPLook: HTTP sniffing made simple

HTTPLook

I'm a small-time web developer/tinkerer, and the occasion is not rare that I need to poke around in the HTTP traffic itself to debug some particularly stick problem. There are some lightweight ways to get the job done most of the time, in particular the excellent LiveHTTPHeaders add-on for Firefox, but once in awhile I need something a bit more robust. On the other hand, there's tools like Ethereal that, though robust, are perhaps too robust. What's needed is something in the middle, like HTTPLook. It's a free Windows app that does one thing and one thing only: Sniff out your HTTP traffic and show it to you in a robust, easy-to-navigate way. To get started, you just have to click on the green Start button, and HTTPLook will record all of the HTTP traffic on your system, in and out, until you click on Stop. After that you can search among the traffic, annotate the data with notes, view or edit entities (e.g. downloaded images or HTML files), and, perhaps most useful of all, filter the data by hosts, return codes (404, 500, etc.), content types, and header fields. On top of that, HTTPLook's help files come with a complete HTTP header reference. If you use HTTPLook, I highly recommend switching to a two-pane mode that will show you both the request and response side by side.

Update: Reader Qwfwq points out that the HTTPLook download is a 15-day trial and it seems no longer possible to purchase the registered version. Big oversight on my part. Reader Peter suggests Fiddler, which is a lot like HTTPLook, has some nice-looking add-ons, and is definitely free.

HFT: Quick-and-easy HTTP file server

HFSHFS stands for HTTP File Server, and it's a free app that makes it easy to set up and run a file server on Windows. Meant for making files available to your friends over the web, HFS has both download and upload modes, bandwidth control, HTML templates, user authentication, logging, and connection control, and can be toggled between Easy and Expert modes. On top of that, it's a 600kb download and comes in the form of a no-install executable, and it's open source, too.

[Thanks, Robin!]

The World's Hardest Game 2.0 - Time Waster

So, just how good at time waster games are you? Think you've got the stuff? Well, The World's Hardest Game 2.0 doesn't think you do. Yes, amazingly, it's possible to have a sequel to a game called "The World's Hardest Game". It doesn't seem logically possible, since if the first one was actually the world's hardest, how could another one come along and share the moniker? It made me doubt the name in the first place. That is, until I tried the game. The mechanics of the game are very simple. You are a small red square, ...
