TBali - Personal Coding Page

A collection of my coding-related activities.

CodinGame

• My CG profile
  • My main focus has been so far on solo I/O puzzles (>97% solved), but I also like to participate in multiplayer bot AI contests.
• My article on CG’s blog:
  • The Coding Adventures of a Salesperson … or how I became a Legend in 40 days
• My playgrounds (articles) on tech.io:
  • A Babel of Languages on CodinGame
  • Swapping languages on CodinGame (a.k.a. system() calls)
  • PHP Dev Tools (for CodinGame or elsewhere)
• Public repositories:
  • CGTest - a multi-language offline batch test runner for CodinGame (or other) solo I/O puzzles
    • The repository also contains 6300+ test cases for 850+ CodinGame puzzles and 760+ puzzle statements.
  • codingame_api - data download tool using CodinGame API

Other coding competitions and sites

• Advent Of Code - (profile is hidden)
  • Solved all puzzles of the first 9 seasons (I used ~10 hints from reddit).
  • Repository of my solutions in PHP
  • Repository of my solutions in Rust
• Codewars - (my profile)
  • So far only minimal activity, ~300 katas solved.
  • Used it to practice simple puzzles and one-liners in PHP and Rust. My personal FP challenge: avoid for loops in my solutions.
• Project Euler - (profile is hidden)
  • Only recently started (<10% of the puzzles solved).
• Google CodeJam
  • Participated in 2021, made it only to round 2… :-(
• Hackerranks - (my profile)
  • (So far only minimal activity)
• On my TODO list:
  • Try out also these: Codeforces. TopCoder, Kaggle, etc.

Aviation Fanatic website

www.aviationfanatic.com - Free online aviation encyclopedia

• I created this website in 2011, as a pet project to learn PHP, MySQL, HTML and CSS.
• Therefore, I decided NOT to use any web framework or external package, except the core language library, doing everything from scratch.
• Now it hosts 260k+ records in 20+ database tables, and 12k+ pictures (plus thumbnails).
• On mid-term TODO list: complete rewrite with OOP design, using Laravel framework and Tailwind CSS. Possibly also with client-side rendering with Vue.js.

Coding in the 90s

I used to code a lot during my high school and university years, mainly in Turbo Pascal (~30k lines of code).

• Repository of the programs I wrote in the 1990s

Commodore 64

It all began with the C64…

• Captain K.O.
  • My very first program, written at the age of 12, in C64 BASIC. It would not pass a decent code review, I know… :-)
• Bali’s Sprite Designer v4.0
  • My very first assembly program. Its first version was written at the age of 15.
• Bali’s Character Editor v2.0
  • A font editor with pull-down menus, written in assembly.
• C64ASM v1.1a - a cross-assembler for the MOS6510 CPU
  • I wrote this in the ’90s in Borland Pascal. It runs on a PC (needs DOSEMU nowadays), but generates C64 binary files that can be run with a real C64 or with an emulator.
• My profile on the C64 Scene Database
• Repository of the C64 programs I wrote in 1986-91

Programming languages

• I consider myself fluent in PHP.
  • I wrote ~160k lines of code (as a hobby).
  • Beginner level in the Laravel framework.
• I used to be fluent in Pascal and C64 assembly in the 90s, but I have mostly forgotten it since.
• Low-intermediate level in C, C++, Java, Javascript / Typescript, Python, Rust
  • I spent some time learning these languages, but have only little coding experience in these.
  • I am able to read/understand code and to write simple stuff.
• I also tried out many other languages (mainly on CodinGame, with < 2k total lines of code per language), so I am at very beginner level in these.

Professional

I have been working in the ICT industry for 25+ years, but never as a software developer.
