Well done. Not an easy feat I know from experience. I did the same for some basis/assembly programs for the Acorn Atom. Recovered those from tape.

If you want to design your own language, you might want to start with IParse Studio, an interactive online parser that parses input according a grammer at every keystroke returning a parse tree, if the input can be parsed according the gram

I think that the following PROMELA code proofs it: byte n = 0 byte A = 0 byte B = 0 proctype Client(byte id) { do :: (A == 0) -> B = id :: (A == id) -> n = n + 1;

The idea is that there is one task that does the locking. It does so by copying a value from a memory location A to B, when B is equal 0 (the initial value) at regular intervals. Any task that wants to get the lock, writes a unique task ide

Interesting. Ik looks like all the colord have the same brightness and saturation. There is s Dutch artist, Peter Struycken, who has been making art works and color pallets (for offices) on these priciples.

In 1995, I started with a personal website based on HTML. Since then, I have added a little bit of CSS to the home page, but all the other files are in plain HTML. For that reason it looks very old school, but that is okay with me. I have b

This implicitely assumes atomic assignments, meaning that during an assignment all bits representing a value are transfered in one atomic unit. This sounds a bit trivial, but if one would be working with large integers that are stored in mu

Look for the file MarkDownC.cpp and search for 'elipses', which stands for '...'. The code makes use of AbstractParseTreeCursor, which is a kind of smart pointer. (The is quite a bit of code that is commented out.) You c

For 'Advent of Code' I have been using a kind of literary programming method based on Markdown files. I have written a parser that can read Markdown files with segments of C code and put all the segments in the correct order to be

I do remember that Scotland was mostly colored orange and the area around London blue. Now it is the way around.

Would it more intuitive to swap the colors in the example: blue for more presperation (water) and red for higher temperatures?

Would it be fair to name the program 'Hello World!' and than use argv[0], which is on the stack, to print out 'Hello World!'?

My wife has done a lot of genealogical research and has experience with reading cursive text going back to about 1700 in both Dutch and German. (Many Dutch people have German ancestors.) A lot depends on the quality of the scans. You can co

On November 21, 2024, 6:35 UTC: It looks like the pilot ship Styrbjoern is traveling in the direction of the Yi Peng 3 bulk carrier again.

It looks like that the pilot ship Styrbjoern [1] came along side the Yi Peng 3 today. It traveled from the harbor of Grenaa to the ship and back. It possible that they took some people in for questioning or put a pilot and/or guards on

A memory mapped file can be used to store complex object oriented structures if you make use of 'relative' pointers, where you have to add the address of the pointer to the pointer to get to the object you are pointing to. I once

As some who has a dis-harmonic intelligence profile, this has been obvious for a very long time. In the family of my mother there are several individuals struggling with language while excelling in the field of exact sciences. I very strong

There are still applications (especially with embedded devices) where you do not dynamically allocate memory or might not even use pointers at all.

Took me the longest (about 40 years) to memorize 7x8. Before being able to memorize it, I would usually add 7 to 49. For some reason, the squares stuck in my mind rather easily. So, 7x7 and 8x8 are easier. I cannot remember having problems

A long time ago, I wrote a page about various reported solutions for this problem [1]. It must have been around 1978 that I first heard of this puzzle. I am not sure, if I did find the solution by myself. (I just noted that the page contain

It seems that many imperative languages make have different types of assignments. C# also treats structs and classes differently with respect to assignment. This not always very transparent differences can lead to some of the nastiest bugs,
