    If you want to get into RF, and not just for hacking a few specific protocols, an RTL-SDR is a better choice and much, much cheaper than a Flipper Zero. For $40 on Amazon you can get an RTL-SDR.com kit complete with antennas that will let you capture data from smart meters, aircraft beacons, police radio, and even detect individual cars driving nearby by capturing serial numbers from their TPMS sensors.








  • I hold a grudge against the translucent plastic fad.

    Once upon a time the Linux workstation at my desk at $CHIP_COMPANY was built into a noname transparent teal ATX case. For that reason I gave it the hostname “fugly”.

    We had excessive field failures with some of our chips, and I was tasked with coming up with a way to identify those bad parts at customer sites. My solution was a bootable Linux CD that would run a test and tell the customer if they need to contact us for a recall. The test relied on a modified Linux kernel, so it couldn’t be distributed as an application. I used “fugly” to develop and build the test, patched kernel, and CD image.

    The test was deployed, the first few customers were pleased, and I got a wood plaque and bonus for my efforts.

    A few weeks later, my manager called me into her office looking uncharacteristically pissed off. She asked why I put a message saying “fugly” into the CD. A customer complained about it, saying they saw “fugly” on the screen when the test was running, and while it did it’s job it was unprofessional. A split second of confusion before I realized what happened: at boot time the Linux kernel prints the name of the machine it was compiled on, in this case fugly.team.company.com . It scrolls past quickly on boot, so neither I nor my collaborators ever noticed. Somehow the customer latched onto it.

    I ended up with a slap on the wrist, being put on PIP for 6 months and having to change the hostname because higher-ups needed their pound of flesh.

    Coincidentally, a week after this incident, Toyota posted a billboard at a major intersection near our office advertising the Scion xB that read “Funky? Or Fugly?”.
