Esta celebración es en conmemoración al nacimiento de la inventora y actriz austriaca Hedy Lamarr.

Lamarr es conocida por la técnica de modulación empleada en el área de telecomunicaciones para la transmisión de datos digitales y por radio frecuencia llamada espectro ensanchado de radio frecuencia.

Este desarrollo fue clave para el desarrollo de las comunicaciones actuales como el y el

Before you decide to click away, thinking we’re talking about some heart rate monitor that connects to a display using WiFi, wait! Pulse-Fi is a system that monitors heart rate using the WiFi signal itself as a measuring device. No sensor, no wires, and it works on people up to ten feet [30 meter] away.

I met an engineer(!) who thought that switching from a 4G Internet router to fiber glass Internet would boost the signal strength in his Ethernet sockets and of his so that it'd reach more corners in his house. 🛜

He further thought that he'd be able to drive his 4K TV screen for streaming high-res videos using a 7 year old 200€ laptop on HDMI. The poor thing even struggles to run very basic apps because of his very limited hardware features. He also accused the 4G Internet router for the resulting streaming issues. 📶

I spend several hours to explain things to him. And now he's going to buy a used (lenovo) notebook to run on it, which I showed to him briefly. 👍

(Btw, + perfectly integrates the whole shit.)

So, people actually *want* to learn. We just don't teach the right stuff.

According to sources like https://forum.openwrt.org/t/not-enough-space/126003 or https://hamy.io/post/0016/how-to-properly-remove-luci-from-openwrt/ or https://forum.openwrt.org/t/removing-luci-from-the-system/31832/4 I can not even remove packages like since they are part of the firmware.

Without any SD card option for extending the storage (it's an outdoor router https://openwrt.org/toh/tp-link/cpe210) I can't update OpenWRT 24.10.0 any more and I can't do anything about it.

So my 3yr old router needs to be replaced? Really? 😲
