Y no os quepa duda: llegará el día en que os dirán que todas las tecnologías de radio convencionales son “obsoletas” y que lo que toca es la radio por Internet o IP, que realmente no es radio, pero que estará bajo total control de los gobiernos de turno: medible, rastreable y

A call for scientists to halt the spoiling of the night sky with artificial light and satellites Scientists should do more to stand up to ‘big light’ and ‘big space’ and preserve this natural resource. Nature Astronomy online:

I was curious about Xscreensaver's XAnalogTV screen saver. It turns out that this guy (@tlbtlbtlb) wrote an analog color TV modem with various channel impairments just to have a realistic analog TV effect.

Mañana toca excursión a Canencia con algunos amigos a observar lo que quede de las Perseidas. Y como todos los años, toca sacar la antena para escuchar ecos de radar de las estelas de los meteoros. A ver si esta vez escuchamos (y vemos) uno gordo. CC @cefalopodo

After every post we make about handwritten we are told the compiler can do a better job. Here's a great example (from HN user ack_complete) showing numerous compilers making a mess of a simple saturated add (a single paddusb on x86): https://t.co/Nzz0pQ57BS

PERO ESTE QUIÉN ES. No he visto el fútbol en mi vida. Ni a este señor. ¿Qué distopía es esta? ¿Qué tiene en la cabeza el juez que ha escrito esa sentencia? ¿Así de desamparados estamos los españoles?

The 10-hour blackout in Spain confirmed that switching power supplies have destroyed amateur radio. 10 hours of noise-free bands and extremely weak signals with crystal-clear audio. Just incredible! But everything went to hell when the power came back on.

Spain is censoring the internet by blocking @vercel CDN IPs, which is the front door of millions of applications and websites. We’re working hard on mitigations to restore freedom of speech as we can, as they’re uncommunicative, secretive & undeterred by users’ complaints.

Vercel's principal engineer verifying how @movistar_es and @LaLiga are blocking a whole country (Spain) from using their services. This makes my blood boil, how TF is this allowed? I swear we live in China. Cc: @Tebasjavier @levelsio

Por ejemplo, ayer hemos tenido en casa problemas con GitHub por la mañana. Menos mal que ayer fue _solder day_ y pudimos seguir trabajando offline, pero me llega a pasar esto la semana pasada y me muero.
