Re: "A QR code can easily contain a link to a scam or a blob of malicious binary information"

I think that was meant to be read with slightly different emphasis:
"A QR code can easily contain a link to a scam, or a blob of malicious binary information".
OK, any form of URL can link to malicious content, but I think the point is that the QR code itself has enough space in it to contain a useful buffer overflow targeted at the QR software itself.
Not many people would type in a printed URL like "http://www.theregister.co.uk\n\n000000000000000000000000000000000000000000000000xdeadbeef", but a QR code neatly gives you the ability to blob that right up.
Two lasers mounted on a simple servo platform, one each in the bottom two corners of the garden.
A sensor on the bot.
First laser starts a sweep, bot reports when it sees a laser flash. This gives you tangent from one laser scanner.
Second laser does the same. This lets you triangulate the bot's position.
Run a grid of wire under the lawn.
Have a low-powered transmitter on the bot.
You can then sense where the bot is by seeing which horizontal and which vertical wires have the strongest signal on them.
You could reverse it and have slightly different frequencies transmitted down each horizontal and vertical wire... might get a bit noisy though!
It's because this attitude is pervasive throughout the OS. It's not just the WM baby they threw out with the bathwater, it's now the menu system they're tinkering with.
Every time they touch something, they throw out n*10 years of work and bugfixes and smoothed rough edges.
The last improvement I found was that init scripts have been moved to Upstart, a dependency-based bootup system. It's done nothing for usability, it's now not immediately obvious what will start up on a system and it's different to everything else for zero gain (I mean, who /cares/ about bootup times any more?).
Maybe i'm getting old, but I find myself agreeing with jwz a lot of the time.
"But that's what happens when there is no incentive for people to do the parts of programming that aren't fun. Fixing bugs isn't fun; going through the bug list isn't fun; but rewriting everything from scratch is fun (because "this time it will be done right", ha ha) and so that's what happens, over and over again.

Yes.
"ALMOST 30 years after fining NASA for littering the local area with debris from abandoned space station Skylab, the Shire of Esperance has received a $US400 cheque.
American radio station Highway Radio paid the fine on NASA’s behalf, raising the funds on variety breakfast program Barker and Barley in the Morning. "
