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.

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.
