Most websites and applications ask users to create accounts with secure passwords so that they can provide tailored user experiences. While this tips the odds in favor of website developers, it certainly doesn't make life easier for users. Sometimes the rules for creating passwords are so strict that it's hard to get a good and allowable combination.

When you write an application, you often want users to be able to configure how they interact with it and how it interacts with their system. These are commonly called "preferences" or "settings," and they're stored in "preference files" or "configuration files," or just "configs."

Many of the documents you receive come in PDF format. Sometimes those PDFs need to be manipulated. For example, pages might need to be removed or added, or you might need to sign or change a specific page. Whether good or bad, this is the reality we all live in. There are some fancy graphical user interface tools that let you edit PDFs, but I have always been most comfortable with the command line. Of the many command-line tools for this task, the ones I use when I want to modify a PDF are qpdf and poppler-utils. read more

Specialized tools and a "shift-left" approach make it possible to verify a Kubernetes schema before it's applied to a cluster. This article addresses how you can avoid misconfigurations and which tools are the best to use. read more
