`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:
Public repositories:
- CGTest - a multi-language offline batch test runner for CodinGame (or other) solo I/O puzzles
  - The repository also contains 6500+ test cases for 870+ CodinGame puzzles and 770+ puzzle statements.
- codingame_api - data download tool using CodinGame API

Other coding competitions and sites

Advent Of Code - (profile is hidden)
- Solved all puzzles in the first 10 seasons (I used ~15 hints from reddit).
- Repository of my solutions in PHP (500 AoC ⭐)
- Repository of my solutions in Rust (218 AoC ⭐)
Everybody Codes - (profile is hidden)
- Only recently started, few solutions in Season 2024.
- Repository of my solutions in Rust
Codewars - (my profile)
- Limited 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)
- Limited activity (<10% of the puzzles solved).
AtCoder
- Very limited activity so far
- Repository of my solutions in Rust
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, 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.

Programming languages

I consider myself fluent in PHP.
- I wrote 220k+ 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.
Nowadays I am spending some time in getting better and practicing Rust.
Low-intermediate level in C, C++, Java, Javascript / Typescript, Python
- 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.
