jQuery Performance, George Dyson, VLC 2.0, and Power Laws

  1. Stop Paying Your jQuery Tax (Sam Saffron) — performance advice for front-end developers. The faster your site responds, the more customers will use it.
  2. George Dyson Interviewed (Wired) — a different perspective on computing, worth reading.
  3. VLC 2.0.0 — VLC lets you bypass manufacturers’ designed-in brokenness so your computer can play media. Glad to see it still being actively developed.
  4. Critical Truth About Power Laws (Science Magazine) — Although power laws have been reported in areas ranging from finance and molecular biology to geophysics and the Internet, the data are typically insufficient and the mechanistic insights are almost always too limited for the identification of power-law behavior to be scientifically useful (see the figure). Indeed, even most statistically “successful” calculations of power laws offer little more than anecdotal value. (no PDF available unless you pay, because that’s how great science works)

PHP Virtual Machine, Archive Your Tweets Easily, Prioritize Your Links, VC Memes

  1. The HipHop Virtual Machine (Facebook) — inside the new virtual machine for PHP from Facebook.
  2. PHP Fog’s Free Thinkup Hosting (Expert Labs) — ThinkUp archives your tweets and other social media activity for you to search, visualize, and analyze. PHPFog hosts PHP apps scalably, and I’m delighted to be an advisor. Andy’s made a video showing how to get up and running with ThinkUp in 3m. (This is impressive given how long I squinted at ThinkUp and swore trying to get it going on my colo box just a year ago)
  3. The Secret Lives of Links (Luke Wroblewski) — notes on a talk by Jared Spool. On the Walgreen’s site, 21% of people go to photos, 16% go to search, 11% go to prescriptions, 6% go to pharmacy link, 5% go to find stores. Total traffic is 59% for these five links. The total amount of page used for these 5 links is ~4% of page space. The most important stuff on the page occupies less than 1/20th of the page. This violates Fitts’s Law. Makes me think of the motor and sensory homunculi.
  4. VC Memes — the success kid is my favourite, I think.

From Reddit to Movie, Google Audited, Web Delays, and Sugared CSS

  1. Story Written in Reddit — historical scifi based on the question “Could I destroy the entire Roman Empire during the reign of Augustus if I traveled back in time with a modern U.S. Marine infantry battalion or MEU?” Movie rights were just acquired by Warners. (via BoingBoing)
  2. Auditing Google — the comically complex games played to move profits to jurisdictions beyond taxation is under scrutiny, at last. While you dodge taxes like this, you have no high moral ground for “do no evil”.
  3. Frontend SPOF Survey (Steve Souders) — a “frontend SPOF” is any crap whose mere presence can delay the display of your web page. We’ve been bitten by this on Radar: “ooh, let’s try this widget—wait, now it takes 12s to load a page, wtf?”
  4. Syntactically Awesome Stylesheetsan extension of CSS3, adding nested rules, variables, mixins, selector inheritance, and more. It’;s translated to well-formatted, standard CSS using the command line tool or a web-framework plugin.
