“No permitiré la mexicanización de Francia”, 🇫🇷 declaró Marine Le Pen al lanzar su campaña presidencial. La frase duele profundamente. A finales de los 80 recorría Europa de mochilero. Recuerdo cómo en las fronteras revisaban exhaustivamente a otros jóvenes sudamericanos. A nosotros, al ver nuestro pasaporte mexicano, nos recibían con una sonrisa y nos dejaban pasar. Ser mexicano abría puertas. Nuestro país despertaba simpatía, respeto y confianza. Casi 40 años después, escuchar a una candidata presidencial europea utilizar el nombre de México como sinónimo de narcotráfico, violencia y crimen organizado es devastador. Y lo más doloroso es que millones de mexicanos honestos y trabajadores terminan pagando el precio de un desprestigio que no provocaron.

A gentle reminder to teams building agentic systems. Have fun; enjoy the process of exploring novel architectures involving flashy new toys; learn new things along the way. However Don’t forget that you are building these things to solve a real problem. Your customers require results; they need value; they want solutions.

Algún día cuando ya estén grandes entenderán que la “derecha” y la “izquierda” es un cuento que les venden para seguirlos manipulando. Solo existen los intereses.

¿Ya se les olvidó? Ariadna Montiel hoy se da baños de pureza. Pero fue denunciada por peculado... ¡ en el año 2023 ! Según la denuncia, desvió dinero del pueblo a Morena y a Claudia Sheinbaum. ¿Y que creen? La denunció fue de una diputada.. ¡ DE MORENA ! Inés Parra Juárez, denunció a la Sria. del BienestarMxOax ante la FGR por quebrar el erario público... ¡ por $6,068 millones de pesos! 👇

If builders built buildings the way programmers write programs, then the first woodpecker that came along would destroy civilization. -- Gerald Weinberg, The Psychology of Computer Programming, 1971.
Replying to @TaliaRinger
The fact that we tolerated a world where basically all our software was insanely buggy and everyone knew this is kinda crazy when you think about it for a few seconds.

Everyone in tech is panicking about security right now. But outside of it, almost nobody knows anything is wrong. I wrote this so you don’t have to be the one explaining it to your family. Just send them this.

The eMudhra compromise is an absolute joke. This isn't a standard data leak it's pure, unadulterated structural incompetence. 8 globally trusted intermediate CA keys were generated with basically zero cryptographic entropy. 😠 A standard NIST P-384 private key needs 384 bits of entropy so it's mathematically impossible to crack. Yet, the blokes at @eMudhra generated production keys with 3 to 8 bits. The actual private key values were literal single digits like 4, 56, and 115. This is playground-level stuff. Infuriatingly amateur. How does a private company with zero fundamental grasp of public key infrastructure even get global root trust? Indian regulatory and auditing bodies make us look like complete idiots. They treat cybersecurity like a casual compliance checkbox instead of critical national infrastructure. This failure leaves the entire internet with a massive cleanup job. Browsers blocked these keys fast, but millions of unmaintained Linux distros, embedded IoT tech, Docker containers, and backend apps are completely exposed out there. If you're an everyday user (not a developer), you still need to fix this on your personal devices right now: Update everything: Force-update your web browsers (Chrome, Edge, Firefox, Safari) and your operating systems across your laptop, Mac, and mobile phone. Don't wait for auto-updates manually trigger them in your settings. Test your device: Go to emudhra.we-have-a-problem.co… Verify the result: If your browser blocks the site and says "Did not connect" (or throws a certificate error), you are safe. If the website opens normally, you are still vulnerable. If you're running Linux, Python, Go, or Node infrastructure: Stop what you're doing. Manually update your ca-certificates bundles, pins, or drop a system-level blocklist immediately to prevent traffic interception. The casual negligence of these agencies shouldn't be your vulnerability.
