I was just having this conversation the other day with a few of my fellow writers such as +Nick Schiwy and +Fred Scholl. Can't figure out how in the hell Microsoft comes up with Windows 10. I've tried everything possible and the only way I can do the math is to leave out a few major releases along the way.

»Late 2012 it became clear that Oracle MySQL would be releasing the 5.6 upgrade RSN. As we already had the beta running productively since summer 2012, it was clear to us that we would need the ability to roll this out widely once it became Generally Available as a stable release.

Unfortunately, at that time the server count was well in the four digits and rising in preparation of the 2013 high season.

So we needed to make the move from automation to orchestration, being able not only to create new database servers without touching them, but also to deal with a replication hierarchy capacity as a service: How many servers can we move out of service at once for upgrade, how to we automate load balancer configuration, how to we validate an upgrade, warm up databases and move them back into service without creating load impulse responses or similar problems?

We came up with a solution that involves bittorrent to distribute data inside the data center, and some work queue that orchestrates automated systems maintenance reliably. We were able to do the upgrade technically in less than three days, and then decided not to go actually that fast - but upgrading became a normal operational process instead of being a crisis.«

The Baatara Gorge Waterfall (Balaa Gorge Waterfall)

It is a waterfall in the Tannourine, Lebanon. The waterfall drops 255 metres (837 ft) into the Baatara Pothole, a cave of Jurassic limestone located on the Lebanon Mountain Trail.
Discovered in 1952 by French bio-speleologist Henri Coiffait, the waterfall and accompanying sinkhole were fully mapped in the 1980s by the Speleo club du liban. The cave is also known as the “Cave of the Three Bridges."

"This amazing Moses bridge located in the Netherlands gives tourists a unique way to access a beautiful 17th Century Dutch fort.
Dutch architecture firm RO&AD Architecten has designed a bridge that turns everyone into Moses.
The birdge is construsted of wood and waterproofoil, the bridge is entirely submerged save for the upper edge which is almost flush with the waterline. Clever engineering incorporates a pump into the bottom of the bridge to prevent flooding when waters get high."
