Touch-Typing Instruction, HTTP Header Attacks, Sorting Ratings, and Risks of Inspecting Applicants' Facebook Pages

  1. Typing Club — lessons to improve your touch-typing, building you up letter by letter to speed and mastery. Like how I learned, only without the typewriters and the bibs and the roomful of girls. It wasn’t easy being the only boy in typing class, but somehow I managed. (via EdTech ideas)
  2. SQL Injection via HTTP Headers — excellent introduction to how some surprising HTTP headers can be attack vectors.
  3. How Not to Sort by Average Rating (Evan Miller) — so easy to get it wrong, so eye-wateringly complex a formula to do it right. (via Hacker News)
  4. I Hereby Resign (Reg Braithwaite) — not an actual resignation letter, but it highlights exactly why asking to see applicants’ Facebook pages is a bad idea. “If you are surfing my Facebook, you could reasonably be expected to discover that I am a Lesbian. Since discrimination against me on this basis is illegal in Ontario, I am just preparing myself for the possibility that you might refuse to hire me and instead hire someone who is a heterosexual but less qualified in any way. Likewise, if you do hire me, I might need to have your employment contracts disclosed to ensure you aren’t paying me less than any male and/or heterosexual colleagues with equivalent responsibilities and experience.” Ditto “spouse is pregnant so I’m about to take maternity leave just after you hire me”, etc. Those things you spend days thumping into HR that they aren’t supposed to ask about? All on the applicants’ Facebook pages.
