Velocity: Forcing Gzip Compression. Almost every browser supports gzip these days, but 15% of web requests have had their Accept-Encoding header stripped or mangled, generally due to poorly implemented proxies or anti-virus software. Steve Souders passes on a trick used by Google Search, where an iframe is used to test the browser’s gzip support and set a cookie to force gzipping of future pages. # 30th September 2010, 5:45 pm

Jeremiah Grossman: I know who your name, where you work, and live. Appalling unfixed vulnerability in Safari 4 and 5 —if you have the “AutoFill web forms using info from my Address Book card” feature enabled (it’s on by default) malicious JavaScript on any site can steal your name, company, state and e-mail address—and would be able to get your phone number too if there wasn’t a bug involving strings that start with a number. The temporary fix is to disable that preference. # 22nd July 2010, 8:44 am
