Workshop: hands-on CloudStack at DevOpsDays Amsterdam

DevOpsDays Amsterdam CloudStack workshop

GPG on Keybase

Schuberg Philis published our GPG key for on Keybase!

One major problem with GPG is publishing your key in a trustworthy and verifiable manner. is directory of people and GPG keys, much like a phonebook. This is similar to standard GPG key directory servers.

The difference with keybase however, is that an entity can publish their public key, but also cryptographically link or prove certain web identities to that key, such as DNS, Twitter, Github, Reddit, etc.

Another added benefit of keybase is, that users who want to encrypt confidential text to us, but do not have GPG installed, can use:

Simply enter your message, hit 'Encrypt', and copy paste the encrypted output in an email to

Please be aware that we cannot encrypt replies unless we have your public key.

Happy Encrypting!

Reporting from QCon day 3

Yoni Goldberg encourages us to build services
The last day of a conference is always the hardest one to speak at, since typically a lot of the attendees will have a few days of evening activities behind them. QCon is no different, the Friday keynote looks definitely a bit less busy and I'm not the only that's just a little groggy. What we really really need now is an imaginative and inventive keynote to get the blood pumping! Unfortunately, Netflix' Roy Rapoport is not talking to us about the great amazing... read more >

Reporting from QCon day 2

Larry Maccherone talking about agile metrics
QCon day two kicks off with a keynote about cluster management at google, by John Wilkes. John is an experienced speaker and the material is rather good (google is king when it comes to their brand of cluster management!). Unfortunately, I've read most of the papers that his talk summarizes so the main thing I learn is that the cluster management software they use is internally referred to as Borg. John also spends some time talking about kubernetes. He doesn't mean... read more >
