For my link archive [Wayback/Archive] Out of Control. An essay on paradigms, refactoring… | by Kevlin Henney | Dec, 2020 | Medium.
Neither because Kevlin describes how to refactor a basic algorithm to convert Roman numerals into Hindu-Arabic numerals (in part by using the fact that an if statement can be considered a bounded case of a while loop), nor because he splits the resulting algorithm in coded data and coded statements, or because he mentions the [Wayback/Archive] Gilded Rose Kata but because well, you should just read it in full.

I originally missed this as back then I was in the midst of managing trouble in my parental family, unaware I was already having rectum cancer. Then things went fast, not even including the Covid-19 years, so I was glad last year I got reminded of this mid-2019 article:
[Wayback/Archive] Alan Turing Wrote Object-Oriented Code In C And Ran It On BEAM – De Programmatica Ipsum writes a lot of interesting things on programming paradigms, starting with
In his rare 1994 book “Object-Oriented Programming In C” Axel Tobias Schreiner explains how to do inheritance, class methods, class hierarchies, and even how to raise exceptions using nothing else than pure, simple, pointer arithmetic-filled, ANSI C.
then arguing basically most of not all modern languages share the majority of programming paradigms and all these paradigms are repeats of the past:
But none of this is new. Smalltalk, arguably the precursor of object orientation, had collect and select methods which were the grandparents of our more common map and filter functional friends.
What sets modern languages apart is that they the majority covers all the paradigms you might need, just differing in how well they support the paradigm-du-jour.
It means programming language wars should have been a thing of the past for about two decades now.
Please let that sink in.
Oh: if you look for that ANSI C book, here it is: [Wayback/Archive] https://www.cs.rit.edu/~ats/books/ooc.pdf [Wayback PDF View/PDF View]

Here are some of my blog posts on documenting using example domains and example IP-addresses or IP-ranges:
(I really wish that example.org and others would service SMTP with blackhole routing so one can also use it for bogus email addresses in documentation)
The blog posts above were incomplete (IPv6 was missing; IPv4 was not explained), so below are more links that do a better job based on a Tweet from [Wayback/Archive] Julia Evans (@b0rk).

For me, it is always difficult to navigate to the Amazon help pages where you can reach their chat.
These are some of the links; follow the pattern to figure out which domain part you need to replace to get to your local ones:

Download & transfer via USB Transfer Tip: After downloading, use your USB cable to connect your computer and Kindle. Your Kindle will appear as a drive on your computer. Copy your downloaded file from your computer to your Kindle’s documents folder. ❗️Starting 26 February 2025, the ‘Download & Transfer via USB’ option will no longer be available. You can still send Kindle books to your Wi-Fi enabled devices by selecting the ‘Deliver or Remove from Device’ option. Learn more about managing downloads
Amazon will disable downloading of Kindle books after 2025-02-25 (yup: slightly more than a week!):

Running Kubernetes containers on Windows means taking into account a different can of worms than running them on Linux.
