Apnea Coding

Fibonacci series in pure C no talking, using only vim and gcc in terminal, implementing four alternative designs: 1) Recursive: using the typical mathematical definition for Fib(n) 2) Iterative: using loop instead of recursion to avoid call stack overflows 3) Dynamic Programming: using buffer for cached results, calculated only once 4) Analytical: using the solution of the differential equation for Fib(n) Each option has its pros and cons, typically trading code simplicity for resources (recursion) or trading memory (cache) for speed. The purpose of this tutorial is to demonstrate coding discipline when working with very limited coding tools (command-line only in terminal) and alternative designs for use in different situations.

This is an example code for estimating the value of 'pi'. The method is a trivial Monte-Carlo sampling upon a quarter-circle using built-in 'random'. Two different estimations are impleneted: (a) the average area under curve (AUC), which is the (randomized) integral of y=f(x)=sqrt(1-x*x) in [0,1], and (b) the area ratio between the quarter-circle and its bounding box. Since the AUC uses twice the number of samples, it should produce consistently better estimations. Turbo Pascal 3.0 was one of those programming artworks of the early '80s, fitting an editor (external), a compiler, debugger and plenty of room to work with in just 64 KB of RAM. Similarly, it was one of the first programming tools (besides x86 Assemblers) to produce .COM executables directly, since the 'tiny' memory model was the default option at that time.

This is just a small snippet of PHP code illustrating the use of generic variables and console (server-side) scripting. Although PHP is almost entirely focused on web application development, basic syntax and features make it a general-purpose programming choice like other more popular alternatives, e.g. Python, Perl, Tcl, Bash, etc. Enable captions for more details and walk-through.

Quadratic equation (ax^2+bx+c=0) solver in retro GW-Basic no-talking, in emulated 80286 / MS-DOS machine in DOSbox. This tutorial is a taste of how home programming looked like in the early '80s, while also showing how difficult it was to correctly pre-plan all 'goto' conditional jumps beforehand when line numbering and editing was the only way to actually edit the source code.

Welcome to the coding dive. Coding as it is supposed to be. No need to talk, no rush. Take a deep breath, keep it. Empty your mind. Exhale slowly. Relax. Now, let's dive in.
