Jesper Hess Nielsen

Jesper is an all-round geek who has been playing with computers, electronics and radios since age 5. He works as a developer but focuses mostly on all the stuff that goes on around a development team. He enjoys muddling with servers, networks, getting stuff to work, designing systems at a higher level and mostly just running around with his oil can, fixing squeaks as they occur. In his spare time you'll either find him on the water in his speedboat, cruising in and around Copenhagen Harbour, or doing something that likely involves a combination of computers, radios and whisky or beer.

He's quite active in the Cryptoparty community in Copenhagen and you will likely meet him if you turn up at the monthly Cryptohagen event. He's also part of the team working on kicking off the initiative.

Let's do a good, old-fashioned OpenPGP key-signing event! Perhaps with beer?

The concentration of OpenPGP users is probably a lot higher at Bornhack than at many other gatherings. So why not use this opportunity to extend the number of signatures on our public PGP keys?

We'll meet up at some time during Bornhack and exchange keys and verify each other's IDs so we can generate a tightly-knit Web Of Trust. And hopefully have a beer or two afterwards.

To submit your key for… Read more
