Cada sandbox está aislado, con su propio sistema de archivos, red y espacio de procesos. Obtienes acceso <code>sudo</code>, gestores de paquetes y la capacidad de ejecutar los mismos comandos que ejecutarías en una máquina Linux.</p>https://antoniocortes.com/en/vercel-sandbox/Mon, 02 Feb 2026 00:00:00 +0000https://antoniocortes.com/en/vercel-sandbox/<p>Vercel has announced the general availability of <a href="https://vercel.com/blog/vercel-sandbox-is-now-generally-available">Vercel Sandbox</a>, an execution layer designed specifically for AI agents.

No es que sea nuevo - en realidad es de enero de 2026, pero bueno, a veces llega tarde a mi radar - pero la combinación de tecnologías y la historia detrás me parecen fascinantes.</p> <p>Se trata de <strong>TinyEMU-Go</strong>: un emulador de RISC-V escrito completamente en Go, portado desde C usando Claude. Y lo mejor: puedes ejecutar un Linux completo con un solo comando.</p>https://antoniocortes.com/en/post/2026/01/tinyemu-go-curiosity-riscv-emulation/Sat, 31 Jan 2026 00:00:00 +0000https://antoniocortes.com/en/post/2026/01/tinyemu-go-curiosity-riscv-emulation/<p>A few days ago I came across an article that literally left me with my mouth open.

the creation of the web I&rsquo;ve entered &ldquo;review&rdquo; mode and I&rsquo;m highly perplexed.</p> <p>I&rsquo;ve been doing things for the same time (25 years), enjoying, always with the same concept and particularity: Enjoyment and result, but it hasn&rsquo;t been relevant for a long time (which is also not very relevant).</p> <p>I&rsquo;ve realized that the usual thing is to do things within your comfort zone, and I&rsquo;ve never had one or knew one could exist, hence I&rsquo;ve touched and done unusual things or perhaps &ldquo;untimely&rdquo;, when a certain technology could be

ya hace mucho que no es relevante (cosa que tambien es poco relevante).</p> <p>Me he dado cuenta que lo habitual es hacer cosas dentro de tu zona de confort, y yo nunca he tenido una ni he sabido que

size-full wp-image-1901 alignright" src="https://antoniocortes.com/uploads/2015/04/goimg1910.png" alt="goimg1910" data-recalc-dims="1" />Siempre me ha gustado ver y probar diferentes tecnologías, y dentro de estas, como no, lenguajes de programación.</p> <p>Ejemplo de esto fue el uso intensivo que di en su momento, en Arrakis, a <a href="http://www.rebol.com/">Rebol</a> , un lenguaje multiplataforma interpretado, con todo lo que podías necesitar para realizar geniales scripts de limpieza de datos, en una sintaxis “extraña”, pero bella en su planteamiento.</p> <p>El caso de Go fue un poco diferente, porque al igual que me ocurrió con Angular, en su momento (hace varios años) traté de darle una oportunidad, pero toda la información y ejemplos que encontraba eran bloques de código “muy pequeño”, no veía en eso (a mirada de pájaro) que estuviese terminado, parecía un lenguaje más académico/conceptual que algo para su uso real.</p>https://antoniocortes.com/en/what-i-like-about-go/Sat, 25 Apr 2015 00:00:00 +0000https://antoniocortes.com/en/what-i-like-about-go/<p><img class=" size-full wp-image-1901 alignright" src="https://antoniocortes.com/uploads/2015/04/goimg1910.png" alt="goimg1910" data-recalc-dims="1" />I&rsquo;ve always liked to see and try different technologies, and within these, of course, programming languages.</p> <p>An example of this was the intensive use I gave at the time, at Arrakis, to <a href="http://www.rebol.com/">Rebol</a>, an interpreted cross-platform language, with everything you could need to perform great data cleaning scripts, in a &ldquo;strange&rdquo; syntax, but beautiful in its approach.</p> <p>The case of Go was a bit different, because just like what happened to me with Angular, at the time (several years ago) I tried to give it a chance, but all the information and examples I found were &ldquo;very small&rdquo; blocks of code, I didn&rsquo;t see in that (at a bird&rsquo;s eye view) that it was finished, it seemed like a more academic/conceptual language than something for real use.</p>https://antoniocortes.com/como-ver-si-estas-logueado-en-wordpress-desde-go-golang/Wed, 25 Mar 2015 00:00:00
