Deutsche Welle has a documentary on the rise of space-based internet service providers.

Internet connectivity anywhere in the world would be sehr fantastisch!

The digital revolution has radically changed the way we live and work. But more than three billion people are still offline. As with any infrastructure, fast data connections initially reach urban centers. People who live in rural areas, even in rich industrialized countries, often have to get by without reduced bandwidth. Now several consortia are competing to bridge this gap with the help of hundreds of mini-satellites in low orbit.

In this episode of Data Exposed with Sasha Nosov, learn how Azure Arc allows you to leverage Azure Services for your existing database applications hosted on-premises or in other public clouds, without changing or even stopping them.

With the rise of deep learning and quantum computing, there has literally never been a better time to learn linear algebra.

Linear algebra is central to almost all areas of mathematics. For instance, linear algebra is fundamental in modern presentations of geometry, including for defining basic objects such as lines, planes and rotations. Also, functional analysis may be basically viewed as the application of linear algebra to spaces of functions. Linear algebra is also used in most sciences and engineering areas, because it allows modeling many natural phenomena, and efficiently computing with such models.

Learn the differences between the Basic, Standard, and Premium tiers of Azure SQL Single Database.

Provisioning is one component of maximizing the value of your deployment – licensing is another.

In this video with Matt Gordon, take a walk through the differences between licensing by DTU and by vCore and talk about what may be right for you and your needs.
