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.

Direct deep links to Amazon help pages

Posted by jpluimers on 2025/03/28

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:

Fun with Windows Containers – Popping Calc

Posted by jpluimers on 2025/02/14

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

For example [Wayback/Archive] Fun with Windows Containers – Popping Calc explains about the various isolation levels and privileges (through runAsUserName) and this helpful advice:

How Discord Supercharges Network Disks for Extreme Low Latency

Posted by jpluimers on 2024/12/27

A while ago there was an interesting point of using tiered md to both obtain low read latency and write safety on the Google Cloud Platform in [Wayback/Archive] How Discord Supercharges Network Disks for Extreme Low Latency

It is an interesting approach to universally tune performance within the sketched boundaries, but raised some questions as their aim was improving ScyllaDB performance and Unix-like platforms on Google Cloud Platform can supports ZFS.

In this case Discord wanted to improve their ScyllaDB that was already read/written from GCP Persistent Storage and used tiered md to improve that.

den on Twitter: “Kubernetes.” portrayed by Seinfeld characters (Engineering Festivus)

Posted by jpluimers on 2024/12/18

At the end of 2020, in the midst of the Covid-19 crisis, [Wayback/Archive] den (@DennisCode) / Twitter started [Wayback/Archive] Engineering Festivus

The only thing 2020 needed is Seinfeld making a career change and getting into tech.

It is a series of IT parodies that at the time of writing just had its’ 35th episode: [Wayback/Archive] den on Twitter: “Kubernetes.”

Kubernetes

Kramer decided to use Kubernetes for his website. Jerry tries to explain what that entails. Kramer is adamant to do it all himself.

Florian Haas on Twitter: alias kubectl=”TZ=Etc/UTC kubectl”; You’re welcome

Posted by jpluimers on 2024/12/10

Sometimes you need to see a tiny bit of code to have this “aha moment”. One for me was a few years back:

[Wayback/Archive] Florian Haas on Twitter: “alias kubectl="TZ=Etc/UTC kubectl" You’re welcome.”
