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.

Android Peripherals, Security Asymmetry, Teaching on G+, and HTTP Load Testing

  1. DSLR Controller — Android app that lets you remote-control your DSLR. Much being made of the fact that iOS devices aren’t as easy to interface with. For more, see the Wired article. (via BoingBoing)
  2. Asymmetric Security Warfare — I found this nugget buried in this photo shoot talking about the differences between Black Hat and DEFCON conferences: [Mudge, Peiter] Zatko found that it takes about 125 lines of code to create the typical piece of malware and it takes about 10 million lines of code to create sophisticated technologies to protect against it.
  3. Teaching Cooking in Google+ Hangouts (KQED) — I love the many uses of hangouts. To my mind, they remain the unique value-add for G+.
  4. HTTP Benchmarking Rules — Mark Nottingham lays down some guidelines for meaningful and effective benchmarking of HTTP services. Full of subtleties and wile: [P]retty much every server loses some capacity once you throw more work at it than it can handle. A better way to get an idea of capacity is to test your server at progressively higher loads, until it reaches capacity and then backs off; you should be able to graph it as a curve that peaks and then backs off. How much it backs off will indicate how well your server deals with overload.

Gamification Critique, BitCoin Trojan, App Store Abandonment, and SSD Rant

  1. Don’t Play Games With Me — slides from an excellent talk about games and gamification. (via Andy Baio)
  2. All Your Bitcoins Are Ours (Symantec) — a trojan in the wild that targets the wallet.dat file and transfers your bitcoins out. If you use Bitcoins, you have the option to encrypt your wallet and we recommend that you choose a strong password for this in the event that an attacker is attempting to brute-force your wallet open. (via Hacker News)
  3. FT Escapes the App Trap (Simon Phipps) — Financial Times dropping their iOS app and moving to HTML5, to escape the App Store commissions. As Simon points out, they’re also losing the sales channel benefits of the App Store. Facebook are doing similar. (via Tim O’Reilly)
  4. Artur Bergman on SSDs (video) — a short sweary rant he gave at Velocity, laying out the numbers for why you’re an idiot not to use SSDs.

  3. TCP/IP and IMS Sequence Diagrams — watch SYN, ACK, payload, etc. packets to and fro to understand what really happens each time you fetch mail or surf the web. This is what Velocity-type devops performance folks care about.
  4. How to Build a Time Machine (Daily Mail) — extremely readable article by Stephen Hawking about the possibilities of time travel.
