On the Booking Annual Meeting last year (BAM16), the company gave away a Go pro to every employee. Many took them with them on their travels. The result was an amazing amount of material, some of it even good. :-)

The “Best Of” just became a really pretty video.

Quotations from Chairman Trump

Get it here: Quotations from Chairman Trump.

“President Donald J. Trump possesses a great sense of history and himself. A model statesman, he tweets every thought, and more. With one exception, he doesn t suffer fools lightly.

Generations of schoolchildren will memorize these rubies of wisdom from President Trump. This little red book captures history on the fly: insights from the leader of the free world.”

A certificate as seen in a network debugger

In order to communicate securely over an encrypted channel, both parties do not just have to agree on a common set of crypto keys, they also need to prove to each other that they are who they claim to be. If they do not, it is very easy for an attacker to mount a Man in the Middle attack.

The thing that is used on the web and elsewhere to prove identity are certificates, and because no one can know all certificates, certificate authorities are acting as trusted passport bureaus of the Internet. In theory.

In practice, that did not work out so well.

Commuter train to Amsterdam, in Haarlem station (Photo: kris)

An article in Dutch News about crowded trains around Amsterdam.

So Amsterdam, Utrecht, Haarlem and even Hoofdorp are technically different municipalities. In reality, this is not the case: People are living in de Randstand. And especially for Amsterdam, people are commuting between the city of Amsterdam and the cities around it. Trains are running at a very high frequency, basically so often that people have stopped caring about the schedule and just show up at the platform, using the trains like one would use a tram or subway or anything else that runs more frequently that every 10 minutes.
