A nice place to discuss rumors, happenings, innovations, and challenges in the technology sphere. We also welcome discussions on the intersections of technology and society. If it’s technological news or discussion of technology, it probably belongs here.

Remember the overriding ethos on Beehaw: Be(e) Nice. Each user you encounter here is a person, and should be treated with kindness (even if they’re wrong, or use a Linux distro you don’t like). Personal attacks will not be tolerated.

I use them for our printed version of our documentation, each document has a cover page with a QR code pointing to the latest version of the electronic copy.

Handy during an outage, and you don't have to search for the online copy.

Smart! If my company ever digitises enough to make this a possibility, I'll implement (or at least suggest) it!
