I received an email from John Graham-Cumming telling me my code was in the original Terminator movie. And it's true!
Here's the still from the movie:

Purdue University's IDEAS Lab built an autonomous drone that tracks runners through dense forests completely without GPS or cloud networks.
By running 3D LiDAR mapping and obstacle-avoidance AI entirely on-chip, it can weave under tree canopies and predict target movement through blind spots in real time.
Massive implications for next-gen search & rescue and edge AI.

Is the first gen - Intel Core i7 (Nehalem) retro yet (2008)? 🤔
I suppose it's all down to the individual and how old you are really.
Got some AliExpress WiFi antennas I will use to transmit signals in the 2.4 GHz band from a calibrated, stable USRP on a good 10MHz reference to test the stability and noise of my ESP32 SDR

Does anyone remember the time in the 90s when people thought the antivirus vendors were releasing viruses so companies had to buy their products?
Now AI is finding vulnerabilities, writing exploits, and creating threats so fast that the only way to defend yourself is to buy more AI.
It’s starting to feel like the 90s all over again.

New blog post: A high sensitivity ADS-B receiver. I present a new ADS-B receiver written in Rust that outperforms existing open source receivers such as readsb: ~3x more messages in typical real world terrestrial scenarios and ~2000x more in simulated LEO scenarios.
