If submitting forms to Rails, you will need to manage CSRF issues. Rather than conveniently by-passing it by turning off your security, you can use a handy javascript library written by Richard Feldman.

Preface

• I want to solve a problem, as quickly as possible.

There is an interesting book which I stumbled on: “Are your lights on” by Donald C. Gause and Gerald Weinberg. I shall attempt to note down the key points contained therein, along with my own ideas and/or disagreements where relevant.

Each of these mistakes has cost me, and my employer, dearly. Please learn from my mistakes.

Matt Swanson has done a great job describing the ins-and-outs of using hovercards via Stimulus JS. This blog post adds to what is there contained with another feature: (i) the ability to abort / cancel a hover card, if your mouse moves away. This entails hiding the hover card, and/or aborting a fetch request, if made.

Assumptions: let’s assuming you are using Rails, with Webpacker, and you want to display to completely different Elm apps on the same page, and you ALSO want to initialise them based on a particular condition. How would you go about doing that?

The following are a mixture of my thoughts/comments + a summary of what is contained in Basecamp’s “Getting Real” book.

Things are complicated enough as they are. Here is a curated list of “simple explanations” (of programming concepts) I’ve prepared. I hope you find it useful:
