Freaking out (not only) mobile app users – xkcd: QR Code

Posted by jpluimers on 2013/07/12

xkcd: QR Code titled “Remember, the installer is watching the camera for the checksum it generated, so you have to scan it using your own phone” is not only freaking out mobile app users (:

The fun starts when putting http://imgs.xkcd.com/comics/qr_code.png through a QR decoder…

The QR paradox: is an infinite loop impossible?

Yeah, yeah 1237: QR Code – explain xkcd got it too: ZXing will parse http://imgs.xkcd.com/comics/qr_code.png fine, then gets you to http://xkcd.com/1237/scan/ which contains http://imgs.xkcd.com/comics/qr_code_loop.png which parses fine.

Which OS X version has which name? (via Wikipedia, the free encyclopedia)

Posted by jpluimers on 2013/07/12

Though Apple prominently advertises with the OS X name, they give Mac users a hard time finding it:

None of the built in options like “About this Mac” or “Software Update…”  tell you the OS X name. They only tell you the OS X version number.

So I grabbed this list from the OS X – Wikipedia, the free encyclopedia. article:

  1. Public Beta: “Kodiak”
  2. Version 10.0: “Cheetah”
  3. Version 10.1: “Puma”
  4. Version 10.2: “Jaguar”
  5. Version 10.3: “Panther”
  6. Version 10.4: “Tiger”
  7. Version 10.5: “Leopard”
  8. Version 10.6: “Snow Leopard”
  9. Version 10.7: “Lion”
  10. Version 10.8: “Mountain Lion”

This list was correct at the time of writing, but Wikipedia probably keeps a better track at updating than I do, so after publication my list might lag behind.
