Is it a common experience for those who own Epson printers that, after it's been idled for a short while, you have to power cycle to get the wifi connection to work to the Mac computer sitting just a couple meters away? Printing and scanning just fails after a short while. Luckily power cycling does not clear the print queue, which I did experience in the past with HP printers.

Trying to decide if it is an Epson issue or my building's wifi router configuration. It's pulling teeth with them to resolve anything, because they insist on phone calls, and I have huge troubles with that method of communcation.

😲 Dall’Università La Sapienza arriva WhoFi

#WhoFi si basa sull’idea che la forma dell’onda del segnale #WiFi viene alterata dalla presenza di ostacoli. I segnali Wi-Fi interagiscono quindi con ossa, organi e composizione corporea, determinando distorsioni specifiche per ogni persona creando una sorta di "firma biometrica" univoca con la quale è possibile identificare un soggetto precisamente e su diversi sistemi.

Another example how our #education system fails to prepare our kids for life:

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 #WiFi 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 #Linux on it, which I showed to him briefly. 👍

(Btw, #Debian13 + #Gnome perfectly integrates the whole #Google #cloud shit.)

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

»Humans can be tracked with unique 'fingerprint' based on how their bodies block Wi-Fi signals:
Wi-Fi spy with my little eye that same guy I saw at another hotspot. Researchers in Italy have developed a way to create a biometric identifier for people based on the way the human body interferes with Wi-Fi signal propagation.«

If this is not also used for manipulating advertising of all kinds of interests?

Il vostro scheletro sta trasmettendo in WiFi. Ogni osso, ogni respiro lascia una firma elettromagnetica unica che l'Università Sapienza ha trasformato in sistema di riconoscimento biometrico. WhoFi vi identifica al 95,5% di precisione senza telecamere, attraverso muri e al buio. Ogni router diventa un occhio invisibile che sa chi siete.
