¡Hola!, acabas de aterrizar en mi cápsula, puedes tomar asiento donde gustes.
Me presento, en el mundo de los internets decidí que mi apodo sería "kirbylife" y de vez en cuando me gusta escribir sobre cosas de programación y todo lo relacionado con las computadoras en general, y para hacerlo me creé un blog en la web de los hipertextos y por fin decidí a traerla a este otro espacio de internet, espero les guste lo que leen y, con un poco de suerte, le encuentren utilidad.
## Artículos
{% for post in posts %}
=> /post/{{ post.title | slugify }}-{{ post.id }} {{ post.title }}
{{ post.content | split(pat=" ") | slice(end=30) | join(sep=" ") | split(pat="#") | slice(end=1) | join(sep="") | replace(from="\n", to="") | trim }}...
{% endfor %}
## Info
Este blog está escrito en el lenguaje de programación Rust, utilizando el framework Windmark, con el editor Emacs y cuenta con feeds RSS/Atom.
