I compared 1,489 eSIM plans in 199 countries. Price per GB varies 105x

Disclosure: we run Bitcall, which sells travel eSIMs. The prices below come from our own catalogue, so read them as one provider's prices on one date, not a survey of the market. We wanted to answer a simple question: how much does mobile data cost a traveller around the world? We had the data on our own site, so we turned it into a small price index. Here is how it works, with the code and a few things that surprised us.

I Built an AI 3D WebGL Portfolio Generator That Gives You Full Source Code Export

Hey everyone! 👋 Like many developers, I noticed a frustrating tradeoff when creating a technical portfolio: Option A: Spend 40+ hours coding a custom website from scratch and maintaining it whenever you finish a new project. Option B: Use generic website builders that give you flat 2D templates, charge high monthly fees, and lock your code inside proprietary walled gardens. To solve this, I built MyFolio — an AI-powered 3D spatial portfolio generator that transforms your GitHub repositories and PDF resume into an interactive 3D WebGL website in under 60 seconds, with 100% standalone source co

El que construye la IA es el que más la teme. Y tiene razón

El hombre que dirige una de las IAs más potentes del mundo dice que hay un 25 % de probabilidad de que las cosas salgan muy, muy mal, y en septiembre de 2026 fue más lejos: "durante demasiado tiempo la industria le mintió a la gente sobre el hecho de que esta tecnología tiene riesgos". No lo dice un crítico externo. Lo dice Dario Amodei, el que la construye. Y ahí está la pregunta incómoda: ¿por qué el que está más cerca es el que más miedo tiene? La respuesta no es la de las películas.
