El Java Que Todavía No Conoces

Sat, 03 Oct 2026 01:01:17 -0600

Esta serie nació de algo que me pasó a mí mismo: después de varios años usando Java, empecé a encontrarme con código que, aunque seguía siendo Java, se veía completamente distinto al que había aprendido en la universidad.

Si estás en los primeros años de la carrera, probablemente todavía no te has encontrado con muchas de estas cosas. Yo tampoco las conocía cuando empecé.

Pero bien: Tú ya conoces Java

Y probablemente conoces más de que te das cuenta. Sabes leer y escribir datos a la consola y al disco. Sabes como se relacionan los objetos entre clases padres y clases hijas. Cómo ordenar datos en estructuras en memoria, etc. Creo que si te diera instrucciones de un programa que lea nombres, los guarde en una lista y luego los imprima, sabrías en minutos cómo escribirlo.

So, I made a blog

This is a simple post, something simple to begin with.

I have been thinking on creating a blog for awhile now. I tried, in fact, starting it in Astro, NextJS and SvelteKit. They are amazing technologies and cool to brag about with my colleagues: How I wrote my blog in a weekend using only Svelte, cornstarch and a Chihuahua. However, that did not happen.

I wanted something minimal, no users, no auth, no complicated routing or dependencies… and most importantly, I wanted to start right away with my content. Focus in learning and writing, not in understanding better Typescript or starting another big project that would have made me wait for weeks until it is deployable. Of course, when you are skilled enough you technically could make a blog in a weekend, but I am not. That’s not my case, and that is why I resetted this project for nine times over the last three months.

I’m kosail.

That’s not my real name, you know. But a pseudonym I’ve been using online for a while and that deeply resonate with me. It comes from the name of my favorite fiction character of all times: 琥珀 (kohaku, from Tsukihime), and the title of a song from Aimer, called Sailing (“Sailing miles away 誰のため?”).

I’m from Honduras, and though I’m honestly not completely proud of my motherland situation, it is still my motherland. I am part of it, and it is part of me. Even though I no longer live there, my heart will likely resonate with it for most of my life.
