Remember the incident at the docks when the revolutionaries threw the T-Mobile imports into the harbour? Talk about high tariffs!

Interestingly C and D are both programming languages. That is, there is a programming languages called C and another, D.

I’ll see myself out…

Actually, PDF is a turing complete programming language.

PDF is a simplification and wrapper around the computer language PostScript - a PostScript or PDF doc literally runs on the printer or computer and outputs the rasterisation of the thing you want to print.

PostScript is language based around a stack. You can define functions (which may be fully recursive) that run on the stack.

Here’s a small example:

/ANGLE {
   newpath
   100 0 moveto
   0 0 lineto
   100 50 lineto
   stroke
} def

10 setlinewidth
0 setlinejoin
100 200 translate
ANGLE

1 setlinejoin
0 70 translate
ANGLE

2 setlinejoin
0 70 translate
ANGLE

As such, PDF that’s actually similar to Python, and HTML is closer to something like a JSON or XML document.

Note however that HTML can contain Javscript or WASM programs, but these are embedded rather than features of HTML.

Linux was not muscled like that in 1991 - it’s first, barebones kernel was released in September of that year.

I remember installing Linux on a 90MHz 486 in the mid 90s and it barely ran X server with a simple window manager. And if the machine was turned off while Linux was running, you might not be able to boot again.

Linux now, however, is unrecognizeably better.
