Some notes on running Postfix inside a docker container

Posted by jpluimers on 2025/11/14

The plan was to run a Postfix secondary MX inside a docker container.

Below are many links that might help me to get that going.

For now, I think this is the shortlist of solutions to try:

  • Docker Mailserver
  • Mailcow
  • Mailu

Infinite loops and the True Meaning of DevOps (Forrest Brazeal on Twitter)

Posted by jpluimers on 2025/11/05

[Wayback/Archive] Forrest Brazeal on Twitter: “Multiple people on LinkedIn have commented on this to swear they’ve seen people DELIBERATELY SHIP INFINITE LOOPS to justify their infra footprint That, my friends, is the true meaning of DevOps”

which was sparked because of comments on his [Wayback/Archive] Forrest Brazeal on Twitter: “Not all “utilization” is created equal…” cartoon:

The project started last month 12 years ago in 2014 as the “realtime collaborative visual editor with zero knowlege server” with the commit [Wayback/Archive] and so it begins · cryptpad/cryptpad@1508c7b · GitHub.

Twelve-Factor App methodology – Wikipedia

Posted by jpluimers on 2025/10/22

It was only a few years back that I was reminded there was in fact a methodology for cloud-based apps: Twelve-Factor App methodology – Wikipedia

Despite me following most of the factors there already (similarly that I have been doing agile software development using extreme programming techniques since the mid 1980s, long before it before they got formal in the 1990s and early 2000s), it helps to have a good vocabulary, so below are some links

Interesting: Announcing Cloudflare Email Service’s private beta

Posted by jpluimers on 2025/10/06

Hopefully this new service will shit less than what other mail services have become: [Wayback/Archive] Announcing Cloudflare Email Service’s private beta

Via [WaybackSave/Archive] @levelsio on X: “Cloudflare today launched their own Email Sending service VERY cool, because by default every email service we use for sending for our websites gets acquired by private equity or IPOs and goes to shit It happened to MailChimp, then SendGrid, then Postmark It’s just the nature …”

Kevlin Henney on “configuration is code” in his essay “Out of Control. An essay on paradigms, refactoring…”

Posted by jpluimers on 2025/07/31

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.

Alan Turing Wrote Object-Oriented Code In C And Ran It On BEAM – De Programmatica Ipsum

Posted by jpluimers on 2025/07/16

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:

These days, we are using the offsprings of multiple programming paradigms having unprotected sex with one another in a thoughtful orgy. PHP, C#, Perl, C++ and even Visual Basic have all closures, lambdas or anonymous functions now. F# and Scala can instantiate any class included in their corresponding vendor-provided frameworks. JavaScript implements functions as objects with a single method .call(). Haskell comonads are actually objects. Swift 1.0 implemented instance methods as curried functions.
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]

Upptime: GitHub-powered open-source uptime monitor and status page

I wonder how long this can be hosted on GitHub. Will start using it, just to learn more about the GitHub computing infrastructure.
