Slowing down at work
As a result the level to which my GD has been annoying me has ramped up over the last few days, to the extent that last night I found myself unable to sleep despite having taken my sleep medication. A very weird sensation, the feeling of drugged sleepiness while simultaneously staying unable to succumb to it.
So I'm not fit for much, back to being barely awake and girl fogged. It'll pass, but meanwhile it's extremely annoying.
Fortunately I've been finding some time to play amid the fog. The image above is a QR code. If you're not familiar with them, it's a two-dimensional barcode. I'm interested in them at the moment because they are a quick and convenient way for someone like me to convey a piece of information to a mobile phone, the phone owner simply points their camera at the QR code and their scanning software automatically picks up the information.
So I've been playing with Google Image Chart Editor and the Zxing QR code generator to explore the format. My application needs to pass a location to the phone user, something which should be easy but has slight annoyances (iPhones and Android phones behave slightly differently, for the curious).
When I found myself scanning the barcodes on my groceries to see what information they contained I knew it was time to stop. Tesco tinned tomatoes, for the truly curious, are 000436408451. Fascinating!
