    So the Tor Browser/Firefox identification vuln that just dropped, if I'm reading it right they exploited the hashdos mitigations, which is hilarious.

    @jelte It probably depends on whether you're using GnuTLS or OpenSSL?

    @ujay68 USB-C charging source ports limit their output unless the device either negotiates USB-PD protocol or has some resistors (of negligible cost and size) to request the power passively. USB-A charging source ports don't have any such checks.

    See https://hackaday.com/2023/01/04/all-about-usb-c-resistors-and-emarkers/ for more details.

    I replaced my laser level because the battery was dead and I couldn't get it to charge. It has a USB-C port for charging, which I was using with a C-to-C cable. Tonight, when I was about to throw it out, I saw an A-to-C cable and tried it.

    Charging is occuring. They cheaped out on an SMD resistor that would have cost a fraction of a cent.

    This should be a crime.

    @RoganDawes @AMS @chaos Yup, should work. Though for something wireless, you may want to run SSH over PPP so that it doesn't die the first time a packet gets dropped.

    @mirabilos @AMS @chaos I don't believe so, as a serial port is not a socket.
