I don't think I've ever seen an emerging technology that's driven CEOs from multiple companies to come out in public and ask people to stop saying mean things about it.

@skickar okay okay, after a bit more researching I found it most likely wasn't you but someone else from Retia (I just now realised that it isn't a nickname but your company). Anyway, maybe you can still help? I now found the website but can only see the sold-out kits for 39C3.

Hey @skickar, if I researched correctly you taught the cat lamp soldering workshop at 39C3.
The workshop description states that one can buy a kit on a website. Is there any way to acquire one after congress and/or any information about the project?

LinkedIn annonced that it will use your data to train AI models, and craftily chose to use an opt-out mechanism. Deactivate this in your settings now, if you don’t want to give away your content.

Canonical's interview process is notorious in an industry already notorious for its interviews, Mark Shuttleworth is a total psychopath, and nobody should ever apply at Canonical, but this is a great use of the GDPR:
