He escrit ràpid i amb ràbia: Aproven l'ampliació de l'aeroport amb poques explicacions i sospitosament amb poca festa, poc canapé i poc reel d'instagram. Diumenge 20, 12h a passeig de Gràcia manifestació contra l'ampliació de l'aeroport del Prat. lapersanc.wordpress.com/2026/09/18/l...

It is crazy how this year 21k people applied for the Marie Curie postdoc scholarship and that only about 1.6k of them will get it, with a success rate even lower than in the past (in other words: 13 applicants for every fellowship awarded). The whole academic system is broken.

¿Pero qué le importa al usuario si el problema es de Renfe, de la gestora de la vía que es Adif, de la falta de inversiones o del Sursumcorda, cuando todo depende en última instancia del mismo sitio, que es el Ministerio?

Esto va más allá de una anécdota en las centrales nucleares europeas. Bastantes industrias dependen del caudal de los ríos. A mayor calentamiento global, mayor número de días de parada y mayor impacto. Mientras tanto, no realizan las inversiones necesarias para descarbonizar su proceso productivo.

Sí, mucha rabia los cafés de especialidad y yo no voy a ninguno porque faltaría más, pero habrá que poner sobre la mesa una evidencia: la hostelería española lleva toda la vida sirviendo unos cafés repugnantes, quemados, terribles, asquerosísimos, hirviendo, el puto horror.

Ara que s'ha esfondrat l'obra de Montcada és un dia com qualsevol altre per preguntar-nos per l'obra o, al menys, per com es paga. Recordem que és un projecte que val uns 900M€ que surten en bona part del pla Rodalies, malgrat que no repercuteix en res a la xarxa de transport (és una millora urbana)

In this crazy accelerated marketing-like academia that we are living now, one of the things that can make a scholar stand out is coining a new concept (in a "full academic world"). Sometimes it feels like someone put together two fancy concepts at random and then wrote a paper.

This heatwave in Europe is insane. Over 10 days of beyond tropical nights (above 20C). No one here is prepared for this. Also, weather companies should by default publish pre 1990 averages alongside the forecast. Honestly, failure to do so is yet another kind of climate denial.
Weather forecast for my part of Switzerland, all days above 30, all nights above 20, for 10 days.

Es un poco cansado escuchar discursos que solo critican la situación actual y detectan problemas y aspectos que se tendrían que tener en cuenta. Sin mojarse en soluciones concretas que potencialmente podrian involucrar contradicciones, o decisiones complicadas.
