Reported figures varied by time and source: Bloomberg Línea put the peso at 18.76 (down 0.71%) at 14:36, while El Universal reported 18.96 wholesale and 19.29 at Banamex branches. A 0.95% drop to 18.7962 is consistent with the peso's movement during the session.\n\nBanxico's Governing Board voted on November 5, 2026 to cut the overnight interbank rate by 25 basis points to 6.25%, effective November 6. The vote was 3–2, with Governor Victoria Rodríguez Ceja, José Gabriel Cuadra, and Omar Mejía Castelazo in favor, and Galia Borja Gómez and Jonathan Heath dissenting.\n\nThe cut was unexpected: a Citi survey of 36 banks, brokerages, and analysis groups found 30 expected Banxico to hold at 6.50%. Banxico justified the move by citing continued disinflation and limited exchange-rate pass-through amid slack in the economy. This is a personal commentary offering an example of how Banxico's rate cut affects the dollar exchange rate; it makes no specific factual assertion to verify.\n\nA blog post by Michael Bacarella describes how a false smoke alarm nearly triggered a fire-suppression discharge that could have flooded Jane Street's only New York City datacenter. The incident is documented in the linked post.\n\nA 2019 analysis by Colin McMillen found that 93% of randomly generated paint-splatter images were valid Perl programs, a quirk of Perl's permissive syntax.

Victoria Rodríguez Ceja, la gobernadora, se la jugó."},{"host":"Diego","text":"Y el peso lo resintió. El tipo de cambio se fue arriba de 18.70, con una caída de alrededor de uno por ciento en la sesión del 5 de noviembre de 2026."},{"host":"Sofía","text":"La pregunta es por qué. Banxico dice que la inflación va cediendo y que el traspaso del tipo de cambio a precios es limitado."},{"host":"Diego","text":"O sea, el banco central viendo el vaso medio lleno. Pero hay un detalle: la economía está débil, y eso pesó."},{"host":"Sofía","text":"Aquí es donde me pongo escéptica. Si la economía está débil, bajar la tasa ayuda al crédito, sí. Pero también le pega al peso."},{"host":"Diego","text":"Claro, pero no puedes tener todo. Si no bajan la tasa, el crédito se encarece y la economía se frena más."},{"host":"Sofía","text":"¿Y si el peso se va a 19.50? Eso encarece importaciones y le mete presión a la inflación que dicen que ya va de salida."},{"host":"Diego","text":"Por eso el voto fue dividido. Jonathan Heath y Galia Borja votaron en contra. No es unánime, es una apuesta."},{"host":"Sofía","text":"Y es una apuesta arriesgada. El recorte sorprendió, y los mercados castigan las sorpresas."},{"host":"Diego","text":"Pero también premian a un banco central que actúa. Si esperas a que todo esté perfecto, nunca mueves nada."},{"host":"Sofía","text":"Para la gente en México, esto significa créditos quizá un poco más baratos, pero un dólar más caro."},{"host":"Diego","text":"Y para los que mandan remesas, cada dólar rinde un poco más. No todo es malo."},{"host":"Sofía","text":"Justo. El tipo de cambio tiene dos caras. Lo que sí es claro es que Banxico se movió antes de lo que todos pensaban."},{"host":"Diego","text":"Y ahora la presión está en la Reserva Federal. Si ellos no bajan, el diferencial de tasas se achica y el peso sufre más."},{"host":"Sofía","text":"Hablando de apuestas, hay una historia de tecnología que parece sacada de una película de desastres."},{"host":"Diego","text":"Una falsa alarma de humo casi ahoga el único centro de datos de Jane Street en Nueva York."},{"host":"Sofía","text":"¿Cómo que casi lo ahoga? ¿De qué estamos hablando?"},{"host":"Diego","text":"El sistema contra incendios estaba a punto de descargar agua, y si eso pasa, adiós servidores."},{"host":"Sofía","text":"Jane Street es una firma de trading cuantitativo. Si se les cae el centro de datos, pierden millones por minuto."},{"host":"Diego","text":"El tipo que lo cuenta, Michael Bacarella, dice que la alarma se disparó por un sensor defectuoso."},{"host":"Sofía","text":"Y lo más increíble es que la gente en Hacker News recuerda el huracán Sandy, cuando subían tambos de diésel por escaleras."},{"host":"Diego","text":"Eso sí es amor al trabajo. Diecisiete pisos cargando combustible para mantener los generadores."},{"host":"Sofía","text":"La lección es que la infraestructura crítica a veces pende de un sensor de veinte dólares."},{"host":"Diego","text":"Y que la redundancia no es un lujo. Jane Street tenía un solo centro de datos en Nueva York. Uno."},{"host":"Sofía","text":"Eso es lo que me asusta. Una empresa que mueve miles de millones dependía de que no sonara una alarma falsa."},{"host":"Diego","text":"Bueno, al menos no se inundó.

Perl es tan permisivo que acepta casi cualquier cosa."},{"host":"Diego","text":"Eso dice mucho de por qué Perl fue tan popular y tan odiado al mismo tiempo."},{"host":"Sofía","text":"Es un lenguaje que no te dice que no. Y a veces eso es exactamente lo que no quieres."},{"host":"Diego","text":"Imagínate depurar un programa que es literalmente una mancha de pintura. Pesadilla."},{"host":"Sofía","text":"La comunidad de Hacker News lo rescató como curiosidad histórica, pero la anécdota sigue siendo oro."},{"host":"Diego","text":"Y de curiosidades a productos nuevos: Google acaba de anunciar una API de decisiones para Gemini."},{"host":"Sofía","text":"La idea es que los modelos de Gemini no solo generen texto, sino que tomen decisiones estructuradas."},{"host":"Diego","text":"Eso suena a que quieren meterse de lleno en automatización de procesos de negocio."},{"host":"Sofía","text":"Es un movimiento lógico. Las empresas no quieren un chatbot, quieren un sistema que decida y actúe."},{"host":"Diego","text":"El riesgo es que una IA tome una decisión mala y nadie sepa por qué. La explicabilidad sigue siendo el talón de Aquiles."},{"host":"Sofía","text":"Por eso la API de decisiones es interesante: si Google logra que sea auditable, le gana a muchos competidores."},{"host":"Diego","text":"Y el recorte de Banxico y la nueva API de Google tienen algo en común: la incertidumbre."},{"host":"Sofía","text":"Y en este programa, la incertidumbre es el mejor combustible para la conversación."}]}
