Tech Thursday – iPad simulator, Twitter archives, HTML5 tester and filling blank maps

Every Thursday is Tech Thursday and we give you some very cool technical links to read up on:

• The library of congress plans to archive all public tweets ever written - I hope they'll publish an API, too
• The Boston Globe has an interesting piece on why forcing people to change passwords is ineffective.
• Paul Bakaus discusses the value of progressive enhancement - let the games begin
• Brad Colbow released an amazing iPad simulator in Photoshop
• HTML5 Test is a test suite for your browser and its support for HTML5 features
• Did you know about the hidden Math in Alice in Wonderland?
• Techbelly have a nice YQL and ScraperWiki tool - as they say: Scraperwiki is brilliant. YQL is brilliant. Now, they can get together and make lots of datababies.
• There is an interesting difference between the official Google map of North Korea and this crowd-sourced one.
