This weekend I built a small personal project called Silly Bird FM — A sound radio between friends.
It's like sending mixtapes or postcards from the old post-stamp era, but with real voices.

There was a time when even a rainwater pipe could be a piece of art.
Look at that fish-shaped bronze ornament. It wasn't necessary for the water to flow, yet someone took the time to design it, sculpt it and give an ordinary architectural feature a sense of beauty.
Today, we often choose the cheapest, fastest and most standardized solution. A simple metal pipe does the job, but it adds nothing to the character of a building.
That's what makes this comparison so striking. The difference isn't just between two drainage systems; it's between two approaches to design.
One treated craftsmanship as part of everyday life. The other prioritizes efficiency above almost everything else.
We didn't lose the ability to create beautiful things. We gradually stopped demanding beauty in the things we build.

Сегодня я узнал, что…
Группа советских учёных месяцами тайно проводили вычисления на правительственных ПК под угрозой увольнения, чтобы первыми в мире создать компьютерную анимацию кошки.
Речь идёт о «Кошечке» 1968 года, анимацию которой сделали с помощью дифференциальных уравнений 2-го порядка и компьютера БЭСМ-4 на базе Курчатовского института. Чтобы максимально точно передать движения кошки, учёные наблюдали за своими питомцами, а, когда они отказывались помогать, бегали на четвереньках сами.
Несмотря на то, что работа над «Кошечкой» проходила в годы идеологических чисток, анимация получила одобрение со стороны коллег-математиков. Мультфильм даже разрешили показать школьникам, которые после просмотра задали вопрос: «Понимает ли кошка, что она не настоящая?».

La iridiscencia del colibrí de Anna no proviene de pigmentos reales, sino de una compleja arquitectura microscópica en sus plumas que refracta la luz como si fueran miles de prismas diminutos.
Este fenómeno físico, conocido como coloración estructural, permite que la coronilla y la garganta del macho cambien drásticamente de un tono negro o marrón opaco a un destello magenta intenso con un mínimo movimiento de su cabeza.
Al erizar o acomodar las plumas de su cabeza y cuello, el ave puede proyectar una media luna luminosa o apagar su brillo para camuflarse entre el follaje verde.
Durante la época reproductiva, el macho realiza vuelos en picada a gran velocidad y orienta su gorjal directamente hacia el sol frente a la hembra para maximizar el destello magenta.

Durante i devastanti incendi boschivi in Australia, gli scienziati dell'Università di Melbourne hanno piazzato delle telecamere vicino alle tane dei wombat (vombati). Questi animali scavano complessi di gallerie sotterranee profondi, freschi e completamente isolati dal fuoco e dal fumo. I video hanno rivelato un comportamento commovente: invece di difendere ferocemente il proprio territorio come fanno di solito, i wombat hanno lasciato entrare nelle loro tane decine di altri animali in fuga dalle fiamme, tra cui echidne, piccoli wallaby, lucertole e uccelli, condividendo il rifugio sotterraneo e salvando loro la vita.

I really love this adorable bot...
This mini robot falls over again and again, and its fall tracker only files a report by default.
The documentation says so. A fall is worked out from the direction of gravity as read by the motion sensor, and it shows up in the monitor, and that is all. It is “a report, not a gate”: the robot does not go limp or refuse commands. To make a fallen robot go limp and wait until someone stands it up, the mode has to be switched on separately in the config.
The battery is just as businesslike. The gauge works as a countdown: yellow at 30%, red at 15%, and at zero the service sits the robot down and cuts power itself.
For scale, PopSci uses familiar things: as tall as a terrier, about as heavy as a chicken.
The documentation gives one more case its own entry, a broken orientation sensor: a board that has stopped computing orientation keeps answering requests, so nothing reports an error.

This robot can be hooked up to an AI agent, but the agent cannot send raw commands to its motors.
The mini robots in the video stand on a desk next to a monitor with a control panel open. And the architecture document says it plainly: a confused agent must not be able to command something the robot will execute into a wall. So remote clients (a browser, a phone, a server) send only intents, and the robotd service decides which of them can run. It also owns falls, joint and thermal limits, and safe poses.
Camera and audio run in a separate service, so a video crash does not stop the motors. Three services, Bluetooth for the phone among them, are meant to keep working even when robotd does not respond.
The robot does not store Wi-Fi credentials: the documentation says “We never store them”.
One more detail, on health checks: a control loop running at 60% of its 50-times-a-second target is considered alive and passing its health check.
