AWS and the CLOUD Act

While news of Brexit dominates headlines in the United Kingdom, another important event took place recently in London. U.S. Deputy Assistant Attorney General Richard W.

Command-line tools for Kubernetes: kubectl, stern, kubectx, kubens

If you’ve ever worked with your hands, you know that you can’t do the job right without the right tools. That adage carries over quite well to software development as well. The right tools can make the difference between success or failure, regardless of the underlying technology.

Uber’s Path of Destruction

Since it began operations in 2010, Uber has grown to the point where it now collects over $45 billion in gross passenger revenue, and it has seized a major share of the urban car service market. But the widespread belief that it is a highly innovative and successful company has no basis in economic reality. An examination of Uber’s economics suggests that it has no hope of ever earning sustainable urban car service profits in competitive markets.
