Antifragile Systems and TeamsAuthor: Dave Zwieback This is a short read, but it does a solid job of capturing an important idea: that the healthiest systems and teams aren’t just resistant to change, they actually get stronger through it. Zwieback contrasts fragile organizations - those that try to lock things down and prevent every possible failure - with antifragile ones, which use volatility, mistakes, and small shocks as opportunities to learn and improve. ...

Why even consider templating Dockerfiles? Dockerfiles revolutionized the industry with their simplicity. Each instruction creates a new layer in the image, which is automatically cached. This process integrates well with SCM, where you “commit” the results of one stage and move forward with other changes. The process can be easily parameterized with ARG instructions, similar to ENV but provided during the build. This allows for creating highly flexible builds. For most users, this is more than sufficient. However, there’s a notable exception: Docker base images. ...
