I'm excited to announce my new course! 
"IoT Firmware Development with ESP32 and ESP-IDF" is designed to take you beyond Arduino to building professional #IoT devices with #WiFi, HTTP/HTTPS, MQTT, and SSL/TLS.

Wi-Fi trên máy bay vẫn còn tệ? 
Bài viết trên The Atlantic giải thích lý do! Có thể do giới hạn công nghệ và chi phí.

The Atlantic · Why Is Airplane Wi-Fi Still So Bad?
Hey #TMobile, I couldn't care less if the beta is over! There's rarely a time that the #5g / #4g network wasn't avail. There WAS a time they were both overloaded & therefore #TSatellite didn't kick in! Cos I STILL DID TECHNICALLY have 5g/4g!
What good is #TSatellite if it doesn't take into account real-world scenarios! At least #Apple has #WiFi connection bad? Use #cellular as backup!
What we need is a #WiFi and #Cellular not going through? Use #TSatellite!
THEN I'd pay $10/mo more!

Public #hotspot / #WiFi providers that restrict traffic to port 80&443: Grow a pair. Grow up. Get real.
Well intending users are being punished because of your "security checklist" or some arbitrary certificate. It's 2025 and people deserve better than being treated like criminals just because you felt like it.
Jemand eine Idee wie man Wifi Captive Portals erreicht ohne den VPN auszumachen? Das ging doch noch vor kurzem!?
Mi az a WhoFi?
https://kocka.news/hu/article/hardver/438/mi-az-a-whofi
kocka.news · Mi az a WhoFi?A vezeték nélküli internet, vagyis a WiFi, ma már életünk szinte mindenütt jelenlévő, nélkülözhetetlen része. Arra használjuk, hogy eszközeinket a világhálóra csatlakoztassuk, kommunikáljunk és információt cseréljünk. Képzeljük el azonban, ha ugyanez a technológia, amely láthatatlanul szövi be otthonainkat és városainkat, képes lenne arra is, hogy kamerák nélkül, akár falakon keresztül is azonosítson és kövessen bennünket. Ez a gondolat nem a távoli jövő sci-fi forgatókönyve, hanem egy újonnan kifejlesztett technológia, a WhoFi valósága, amely a WiFi jelek egy eddig kiaknázatlan tulajdonságát használja fel. A helyzetet bonyolítja, hogy a „WhoFi” név egy teljesen más, közösségi célokat szolgáló szolgáltatást is takar, így a kifejezés hallatán fontos tisztázni, melyik jelentéséről van szó.
What is WhoFi?
https://kocka.news/en/article/hardware/439/what-is-whofi
kocka.news · What is WhoFi?Wireless internet, or WiFi, is now a ubiquitous and indispensable part of our lives. We use it to connect our devices to the internet, communicate, and exchange information. But imagine if this same technology, which invisibly weaves through our homes and cities, could also identify and track us without cameras—even through walls. This is not a distant science fiction scenario, but the reality of a newly developed technology called WhoFi, which harnesses a previously untapped property of WiFi signals. To complicate matters, the term “WhoFi” also refers to an entirely different service with community-focused goals, so it's important to clarify which meaning is being discussed.

Via AudioRelay vom PC zum Handy streamen und dort halt gleich zu dem Hörgeräten klappt prinzipiell gerade sehr fein. "Prinzipiell", weil ich noch was mit den Audiogeräten durcheinander komme oder es doch nicht immer auf Anhieb klappt.
Ebenso das Mikro durchschleifen klappt (btw. Quali der Hörgeräte sehr ok). Gut, Mikro ist ja meist eh vorhanden an PCs bzw. Kameras, also noch kein echter Use Case da.

WPA3's Dragonfly protocol changed Wi-Fi security forever!
No more offline password cracking. Every attack attempt must happen live with the access point, making mass attacks noisy and detectable.
But there are nuances...

„Who-Fi“ yra pažangi technologija, kuri naudoja dirbtinį intelektą (AI) asmenims identifikuoti ir sekti be jokios vizualinės informacijos. Tai eksperimentinė technologija, kuri dar turi būti išsamiai išbandyta realiomis sąlygomis. Tačiau remiantis moksliniu straipsniu, kuriame minimas ir aprašomas jos koncepcijos pagrindimas, ji gali būti naudojama bet kokiam įprastam „Wi-Fi“ signalui paversti biometriniu skait https://pamatyti.lt/who-fi-dirbtinio-intelekto-pagalba-veikianti-wi-fi-technologija-kuri-gali-identifikuoti-ir-sekti-asmenis-be-kameru/ #Saugumas #Sekimas #WhoFi #WiFi
WhoFi is a new system that identifies people using only Wi-Fi signals instead of cameras. It uses a Transformer model to analyze signal changes caused by someone walking. On the NTU-Fi dataset, it got 95.5% top accuracy.

Hat zwar halbwegs Spaß gemacht, aber war nur so mittel von Erfolg gekrönt:
Mit #CachyOS habe ich kein #Wifi ans Laufen gebracht.
Mit #LinuxMint lief #Wifi outOfTheBox, aber dafür fand ich kein passendes Tastatur-Layout und scheinbar auch keine passenden Codecs für Videos.
naja.... auch eine Erfahrung.
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.
Securityinfo.it · WhoFi: da La Sapienza arriva un sistema di riconoscimento biometrico basato sul Wi-Fi - Securityinfo.itWhoFi è un nuovo sistema che migliora le operazioni di re-identificazione (Re-ID) sfruttando le alterazioni delle onde del Wi-Fi.
