One of many things I love about Python is how whitespace is an integral part of the language. Python was the first popular programming language designed with the idea that “code is read much more often than it is written.” Forcing authors to indent code in a maintainable fashion seemed a brilliant idea when I first encountered Python fifteen years ago. The lack of braces scattered throughout the code made for easier reading.

The venerable RSA public key encryption algorithm is very elegant. It requires a basic understanding of modular arithmetic, which may sound scary if you haven’t studied it. It reduces to taking the remainder after integer long division. The RSA Wikipedia article describes five simple steps to generate the keys. Encryption and decryption are a matter of basic exponentiation. There’s no advanced math, and it’s easy to understand their example of working with small numbers.

Whenever I start a new hobby web project, I just want to jump in and start coding.
Instead, I spend many many hours trying to get authentication to work. I’ve got half a dozen half-finished “boilerplate” projects lying around that were supposed to satisfy the desire of, “next time, I can use this boilerplate and authentication will just work.” It never does.
One thing I know I don’t want to do is manage my own auth database anymore.

My wife and I both have a tendency to leave the garage door open. You’re in and out, grabbing garden tools or supplies, and at the end of the day you enter the house through the back door and forget to check the garage. Luckily, we live in rural Canada, surrounded by wonderful people, where the door could sit open for days without anything “disappearing”. But it still makes me feel nervous to discover it’s been forgotten, if only because it is a waste of heat in the winter (not to mention the chance of blowing full of snow!
