Plurrrr

It took me a bit of time to get my head around jq's reduce function. In this post I show how it relates to the equivalent function in JavaScript, which helped me understand it better, and might help you too.

It's been almost a year since I've bought the MacBook Pro M1 (arm64 processor) for my daily Java development as a freelance consultant. I had my first contact with the Apple M1 when one of my course students raised an issue that the build doesn't pass on Apple's new flagship laptop. I was first shocked to encounter hardware incompatibilities in 2021. To solve those problems (not my main intent, but I told myself so) and experience if that processor is really that fast, I decided to buy the MacBook Pro.

This article will share my initial pitfalls when working with the Apple M1 and a collection of valuable tricks and workarounds for developing and testing Java applications.

The point of bash-bashing is to reduce use of the shell. Without much real work, it’s easy to replace shell scripts with Python code. The revised code is easier to read and maintain, runs a little faster, and can have a proper unit test suite.

Because shell code is so common, I’ll provide some detailed examples of how to translate legacy shell scripts into Python. I’ll assume a little familiarity with Python.
