I once met a person that never drank water, only soft drinks. It’s not the unhealthiness of this that disturbed me, but the fact they did it without the requisite paperwork.

Unlike those disorganised people I have a formal waiver. I primarily drink steam and crushed glaciers.

    I swear that I read that white lead oxide is water soluble, thus happily sticks to your fingers and then gets on your food. I must be misremembering.

    Maybe it was something about the solid lead object turning into an (oxide) powder that can then be easily ported as tiny particles on greasy hands? Hearsay science and safety information from me today :)

    The fun thing about Pb is it’s relatively safe in pure form. Unfortunately the oxides that appear on its surface are water soluble and love entering our bodies.

    Just looked this up, apparently I’m completely wrong. Maybe I was thinking about lipid compatibility? Not sure now.




  • Bleepingcomputer’s title and article are very misleading, the presentation did NOT reveal a backdoor into an ESP32. It looks like Bleepingcomputer completely misunderstood what was presented (EDIT: and tarlogic isn’t helping with the first sentence on their site).

    Instead the presentation was about using an ESP32 as a tool to attack other devices. Additionally they discovered some undocumented commands that you can send from the ESP32 processor to the ESP32 radio peripheral that let you take control of it and potentially send some extra forms of traffic that could be useful. They did NOT present anything about the ESP32 bluetooth radio being externally attackable.

    Another perspective that might help: imagine you have a cheap bluetooth chipset that is open source and well documented. That would give you more than what the presentation just found. Would Bleepingcomputer then be reporting it’s a backdoor threatening millions of devices?





  • Anything odd with temperatures or power draws perhaps? nv-top shows both for me (but I run an AMD GPU + non-proprietary drivers), otherwise lm-sensors might be good.

    nvtop seems to show normal usage

    Neither the GPU nor CPU utilisation change at the 30 min mark? If one is pegged at 100% then it’s probably hard to work out what is going on. Running a singleplayer game staring at a wall and configured with limited framrate might let you run both the CPU and GPU at less than 100%, perhaps making it easier to see if one or the other suddenly changes.
