Hello again, and welcome back to Five Things Tech!

The sun is shining and we should talk about how repurposing strip mines around the world would deliver as much energy needed to power a country like Germany. There is still so much untapped potential in solar, if you think about it. All those roofs that could use solar. Or balconies. Or parkinglots that need shade and could therefore have solarpanels. If we really want it, we could push renewable energy so much more.

Also, let’s deal with the quantum threat for cryptography as we know it and with hackers exploiting the human factor of call centers. Then we are taking a look at software engineers and how great teams are being assembled. Finally, let’s look at the latest scam the Trumps are pushing.

Enjoy!
