This article titled " Wie die Digitalisierung Wertschöpfung neu definiert " appeared in German last week in the "Größer, höher, weiter (bigger, higher, further)" column of Wirtschaftwoche. Germany's "hidden champions" – family-owned companies, engineering companies, specialists – are unique in the world. They stand for quality, reliability and a high degree of know-how in manufacturing.

Data modeling has a prominent place in the course on high level software development fundamentals. There’s a big chunk of the introductory lesson devoted to it. The second lesson is devoted to it. A future lesson is planned on it. I will also be creating a full course on it at some point. It’s given such prominence because of how important it is in software development.

VoltDB

MAY 2, 2017

We recently received a question from a customer who was looking for a quick way to repurpose some VoltDB production servers to create a disaster recovery site. The customer had a 5-node cluster with a k-safety factor of 2, which means the cluster maintains three synchronized copies of each record, distributed on different nodes in the cluster, and the cluster can survive the loss of any two nodes.

Until a few years ago, enterprise software development was pretty easy to justify and execute because the income statement was the primary customer. Automating back office tasks, expanding market reach, creating customer self-service tools, even legacy technology replacements were all investments that could be explained in a straightforward manner as taking costs out or capturing revenue that would otherwise have been lost.

Speed Curve

MAY 1, 2017

SpeedCurve is a SPA (Single Page App) so we construct the charts dynamically using JSONP. It works great, but we're always looking for ways to make the dashboards faster. One downside to making requests dynamically is that the browser preloader isn't used. This isn't a factor for later SPA requests, but on the first page view the preloader might still bring some benefits.

If you’ve been working towards containerizing your web applications like I have, you might be at a point where you’re ready to start clustering your containers. Previously I had written about creating a container cluster with Docker Swarm and using NGINX as a reverse proxy for a few containers. The catch here is that neither of these previous tutorials were meant to work together.
