On accessibility (thanks Bianca Prins!) and archivability.

Posted by jpluimers on 2025/02/27

A long while ago, I participated in a Twitter thread that started with a translation of some important accessibility posts by Bianca Prins, then extended it to the concept to archivability:

[WayBack] Thread by @jpluimers: “I am going to first translate this, then extend this to archivability…. @jpluimers […]” #UXdesign #accessibility.

TL;DR

  1. make sure what you create is accessible
  2. ensure your (online) content is archivable
  3. help archiving content

Let’s go

Going Native – Malicious Native Applications

Posted by jpluimers on 2025/02/25

On the reading list wondering which tool chains can deliver NtAPI based development: [Wayback/Archive] Going Native – Malicious Native Applications

Via [Wayback/Archive] Thread by @MrPc69257431 on Thread Reader App with first tweet at

https://x.com/MrPc69257431/status/1864855379651498292

Note that being able to call NtAPI from your code base does not mean NtAPI based development: Pure NtAPI means you need a linker that can target a different output. See the quote from the above article (emphasis mine):

So, to get started with an empty native executable, all we have to do is include the “phnt.h” file, and set up the NtProcessStartup function. Then it’s important to tell the linker that we want to link against ntdll, and that we’ll be making a native application by passing in the “Native” text to the Subsystem linker option

It means that for instance Delphi is kind of out of the question for this, see these links on why:

Visual Studio Code: copying text when none is selected.

Posted by jpluimers on 2025/02/19

Last week, I wrote that I switched to Visual Studio Code for most of my text based coding: Visual Studio Code: blazingly fast text expansion with Emmet.

I also use vscode for documentation and text writing, which – yes sometimes I am a copy/paste person too – means you want a bit more flexibility than just copying the selected text.

In most of my previous development tools, either the tool itself, or a plugin, would allow me to copy the word under the cursor if none was selected.

I wanted to change that behaviour too and become more flexible.

So I did some searches:

Old programming books had cool little “puns” in their references, modern lack them in their indices. On the why, and history of them.

Posted by jpluimers on 2025/01/01

I wrote a two earlier blog posts around puns in programming book indices before:

  1. the 1992 Turbo Pascal 7.0 Language Guide having both entry in the manual about Recursion (“recursive loop, see recursive loop”) which of course is similar to “infinite loop” and entries for “infinite loop See loop, infinite” and “loop, infinite See infinite loop”.
  2. infinite loop in “LaTeX: A Document Preparation System” by Leslie Lamport, printed in 1994.

In the last one, I promised to list more occurrences which I now finally had time for to do.

But let me first elaborate more on the observation that modern computer books (like for instance on C# and Delphi beyond version 1) lack these kinds of index pun.

On the Delphi side, the index entry joke for recursion got removed no later than Delphi 3 (I am still looking for a Delphi 2 version of the Object Pascal Language Guide, see further below) even before the book being fully redone electronically and the index pages generation being automated in

I think I even understand why that is: the process of creating of indices. By the start of this century, more and more indices were automatically being generated and for the last 2 decades or so, all of them are. Back in the days however, indices were mostly done by hand. Nowadays, with everything automated, it is actually pretty tricky in most environments to add such an “infinite loop” index entry like in the Turbo Pascal book, as it would require two things at once:

Is it Pokémon or Big Data?

Fron a while ago but still relevant [Wayback/Archive] Is it Pokémon or Big Data?.

It is a cool experiment to test your own knowledge or for fun to assess recruiters or candidates (;

For the USA, the TRS-80 PC-1 was the “The Trash Computer That Became Your Phone”; the rest of the world could enjoy the hardware identical Sharp PC-1210/1211/1212 years earlier

Posted by jpluimers on 2024/11/25

Earlier this year, I bumped into [Wayback/Archive] The Trash Computer That Became Your Phone – YouTube which discusses the Tandy  TRS-80 Pocket Computer PC-1, . The video includes a lot of history about Tandy Corporation, Charles Tandy and Radio Shack including quite a few bits I didn’t know yet.

It was part of the Tandy Pocket Computer, and succeeded by the Z80 powered TRS-80 Pocket Computer PC-2 (which was actually a rebadged Sharp PC-1500).

The TRS-80 Pocket Computer PC-1 itself was also a rebadged Pocket Computer, this time a Sharp PC-1211 powered by a duo of 4-bit CPUs so totally incompatible with the PC-2. Actually none of the Tandy Pocket Computer line were compatible with each other (nor with the desktop TRS-80 which itself was incompatible TRS-80 Color Computer). With the PC-4 and on Tandy even switched to Casio as manufacturer, then back to Sharp for the final PC-8.

Anyway: this video was a trip down memory lane and reliving my 2012 blog post The calculators that got me into programming (via: calculators : Algorithms for the masses – julian m bucknall), and I was glad that by now there are more videos covering the calculator I started with, for instance via [Wayback/Archive] sharp pc-1211 – YouTube:

Posted by jpluimers on 2024/11/22

A long, since 1989, tradition is the Quadrennial Dutch hacker convention.

A nice video summarising all of them is at [Wayback/Archive] GHP1989 to WHY2025: Dutch hacker camps from the past and the future – YouTube

The upcoming [Wayback/Archive] WHY2025 hacker camp convention is covered starting at 44:42.
