Sometimes, while working on the command line (especially when dealing with a shell script), you may find yourself in a situation where you have to perform actions like searching for a substring in a string, finding its index, as well as other things like performing comparisons and arithmetic operations.

You need to set up the IT infrastructure (email, file sharing, etc.) for a new company. No restrictions. No legacy application support necessary. How would you do it? What would that ideal IT infrastructure look like? For starters, everything should be open source.

The widespread use of code from Facebook maintained React.js, a popular developer tool for building interfaces with JavaScript, is the reason why this issue is particularly problematic for Apache. Unless Facebook changes the license, all of Facebook's code will have to be removed from all projects that have been using it. In some cases that might be impossible, meaning popular applications will no longer be available.

If you're launching a company, you might believe you shouldn't have to deal with issues like personnel development and company culture. After all, as a startup you're only concerned with the development and rapid evolution of your own product and services, right? This kind of thinking is short-term thinking. Successful startups develop organizations with long-term strategies in mind. Startups really should think about—and prepare the groundwork for—their own company culture from beginning, so they can scale it over time as they grow.

From my professional DevSecOps perspective securing the containers and the orchestrators (such as OpenShift, Docker Swarm and Kubernetes) is usually far from easy.

Gamer? Check. Linux user? Check. For years, one of the top excuses I heard from friends who would otherwise have switched to Linux long ago is that they just couldn't give up their Windows-only games. I can empathize. I was a dual-booter for years for exactly this reason, and it made making the switch harder for me. After all, once I'm booted into one operating system, the temptation is to stay there rather than rebooting once gameplay is over. Today, the landscape is far different.

There are many ways to do that, but that quickest and easiest way is to use a spreadsheet.
