Graphical adventure

This is not only a graphic adventure in the style of old Lucasarts classics, but also a ENGINE and special language developed to make graphics adventures. This was coded when I was 16 years old using a 486 and mostly ASIC and ASSEMBLER. Programmed around 1998-1999, inspired on Full Throttle and many more adventures (Loom, Day of the Tentacle, etc)
The engine has its own scripting language, which allows creating generic graphic adventures.
Very inspired by old text adventures, and LucasArts games
To play it, use MS-DOS, or an emulator like DOSBOX ... there are compiled binaries and two graphic adventures, a short demo, and a complete graphic adventure to play!

Kronoide

A Breakout / Arkanoide game. Can be played using DOSBOX.
Breakout is an arcade game developed and published by Atari, Inc., and released on May 13, 1976. It was conceptualized by Nolan Bushnell and Steve Bristow, influenced by the seminal 1972 Atari arcade game Pong, and built by Steve Wozniak, aided by Steve Jobs.
Breakout was the basis and inspiration for certain aspects of the Apple II personal computer. In 1978, the game was ported to the Atari 2600 and a sequel was made, Super Breakout, which four years later became the "pack-in game" for the Atari 5200 console. Breakout spawned an entire genre of Breakout clones, and the concept found new legs with Taito's 1986 Arkanoid, which itself spawned dozens of imitators.

KTank

Artillery game for up to 10 players. Input angle and power and try to destroy your opponents.
Features randomly generated destroyable terrain, up to 10 players in hot seat setup.
A very fun game to play on a rainy day!
To play it, use MS-DOS, or an emulator like DOSBOX ...
Note, there used to be a version that lets you play against the computer too (and not only humans), sadly was lost in some crashed diskettes. Will be re-done soon.

KronoDataGrid

I needed a lightweight data grid for some commercial projects, and all were very bloated and expensive, so I developed this super light weight data grid.
Useful things in this project:

• A data grid with editable tools, kronoDataGrid.php
• RANDOM name and surname generator for your projects, in install/index.php and supporting files.
• Lightweight MySQL connect wrapper - Check connectMySQL.php

ERP system

In house 100% developed from scratch ERP (enterprise resource planning) for small companies at Buenos Aires.
The system manages all for the company: clients, reports, roadmaps, business resources, orders, receipts, purchase orders, and payroll.
Developed from scratch using PHP, MySQL, HTML5, Javascript and CSS, running on a Linux Apache web server,
This system really improved the productivity of the small company, maximizing their profits and reducing costs. The ERP system integrates varied organizational systems and facilitates error-free transactions and production, thereby enhancing the organization's efficiency.
Soon I will be releasing original source code from this project, a total open source ERP solution, 100% developed by me, specially targeted to small companies that can't afford very costly solutions like SAP, Oracle, IBM, etc solutions...

NOTE: all data shown on screenshoot is fictional RANDOM data generated for a test system. No private data was shown.

Kr Jr

Once upon a time, I coded a GUI operating system for old computers.
Never finished this huge project, but it is in a stage where it runs and can be tested on old computers or a virtual machine.
You have a working desktop, a working boot sequence and can run MS DOS software and games.
It is SUPER FAST. Even running on a virtual machine emulator, it will work fast. Mostly C and Assembler code.
It can run even in a 386 with 1mb RAM and no HD It fits on a diskette! Recycle your old PC! Inspired on micro kernels such as QNX, but the code is 100% my production, not based on any other kernels.

Bitcoin Swiss Army Knife

Experimental currency converter, by buying cryptocurrencies, using the Bitso exchange.
Serves for Argentine peso ARS, and US dollar USD.
It also allows you to place buy and sell orders, and see the economic indicators.
It is much more efficient and faster than entering the app or the website, since we can do everything from the command console quickly.
This software is my answer to the economic collapse that Argentina is facing, and to try to avoid the hyperinflation.

Spanish characters and MySQL

How to correctly enter the special characters of the Spanish language to MySQL.
Many times we find databases that have entries like "Rubén", "Julián" stored as "Rubén", "Julián", or similar things where the data is apparently corrupt.
In this document we are going to explore the solution to this problem.

Computer technician guide

A computer technician guide to repair your friends and family computer. You are "the" tech guy in the family, don't you?
One of the hallmarks of our age is the decline of the do-it-yourselfer in favor of the hire-an-expert-to-do-it-insteader. Toilet not flushing? Hire a plumber. Porch falling down? Hire a carpenter. Lights on the blink? Hire an electrician.
You could argue, as many people have done, that a return to a DIY ethos would be good for society and good for the soul. I like to DIY. Also, I'm a Computer Science graduate, so I get often called as "the" tech guy in family and circle of friends.

Full stack development notes

My notes for "full stack developer", and some other things.
Here I am going to put links to things that are useful to me in my professional development.
It is addressed to myself, but if it works for you, if it is useful to you, welcome!

Harley Davidson Argentina tips & tricks

Alternative parts list for Harley Davidson Sportster available in Argentina.
Given the country's situation, with constant import bans, it becomes difficult to keep an imported motorcycle running.
That's why I compiled, over more than 16 years, a list of alternative parts to keep the Harley Davidson Sportster running in optimal condition.
This project starts in 2004, when I bought my first HD XL883.
Spanish content ahead.
