It's called "smart dust", and the idea is anything but new.
Are they going to ban them in restaurants next? Movie theaters?
That would be nice. We already know there's a special hell reserved for those who talk at the theater.
CCOHS: Canadian Center On How-to Survive?
Canadian Centre for Occupational Health and Safety, so yes more or less.
Trust the Canadian government to have a web page devoted to how not to freeze to death.
My understanding is that's the "core" temperature, and that extremities drop below that all the time, but I have not researched this at all.
... because what we always need is another standard.
I'm not saying that hobbyist 3D printers are useless, but like any tool their use should be selected against the other available tools.
I am not skeptical about the future of these technologies, I am skeptical about their present.
One day, maybe 10 or 20 or 50 years from now, 3D printing and home fabrication will be playing major roles in our economy and technology development, at the industrial level that has already started for prototyping.
Right now, like script kiddies and regular expressions and the nosql crowd, there are people out there who have a hammer and every problem looks like a nail.
Is that a 3D printed gun in your pocket or are you just feeling suicidal and have a weak grasp on the economics of mass production?
Buy typical cable trays, and 3D print some sort of fancy colorful casings for them. You can use a variety of designs and colors for aesthetic appeal. Plus even if it doesn't look all that great it will still be "cutting edge" technology in use, which will likely appeal to your business folks. Plus you can throw a 3D printer in your budget...
Interesting idea, but given that it takes the average 3D printer hours to create something only a few inches across it's not terribly practical.
It would be more practical to hire a basket weaver... ooh... woven trays...
Put it all together and security is usually a bad joke.
Always act and behave as if there is no security for any device with a network connection, everything else is just some form of wishful thinking.
We don't go to Ravenholm anymore.
