  • Load average of 400???

    You could install systat (or similar) and use output from sar to watch for thresholds and reboot if exceeded.

    The upside of doing this is you may also be able to narrow down what is going on, exactly, when this happens, since sar records stats for CPU, memory, disk etc. So you can go back after the fact and you might be able to see if it is just a CPU thing or more than that. (Unless the problem happens instantly rather than gradually increasing).

    PS: rather than using cron, you could run a script as a daemon that runs sar at 1 sec intervals.

    Another thought is some kind of external watchdog. Curl webpage on server, if delay too long power cycle with smart home outlet? Idk. Just throwing crazy ideas out there.




  • I have a couple Lenovo tiny form factors: an M700 8GB w/ J3710 running Pihole on Ubuntu server—which is total overkill in both CPU and mem; and an M73, 4GB w/4th gen i3 running jellyfin server on Mint 21.3. Certain kinds of transcoding brings it to its knees but for most 1080p streaming it’s fine. Memory is a bit tight; 8G would be better. It has a usb3 2T drive for video files that runs more than quick enough. Serial adapters are available if you want to use the console.

    The latter has been running for I think a couple years. The former I just set up.

    But I’ve been shopping for newer gear for the Jellyfin server. I think you could get a Dell, HP, or Lenovo 6th gen TFF with 8G and 256-512G internal SSD within your price range.

    I see some EliteDesk G800 G3 (6th gen Intel) tinys with no disk for $50-70 shipped on eBay in the US. I think those look the coolest by far :)

    You could find one with no disk, no ram and config as you please and probably still come in under budget.

    E-

    My eventual plan for the Jellyfin server is a SFF, probably an HP with enough space to fit a couple of big HDDs, plus 16G ram and a newer CPU that can transcode on the fly without lag.






  • Yes it can be used to steal some cars.

    Banning it because it can be used to steal cars doesn’t make sense

    Btw… Some folks may not realize it is a go to tool for many things.

    Flipper Zero - Wikipedia Flipper Zero is a portable Tamagotchi-like multi-functional device developed for interaction with access control systems. The device is able to read, copy, and emulate RFID and NFC tags, radio remotes, iButton, and digital access keys, along with a GPIO interface.

    It is a swiss army knife for RF access control systems as well as harmless, related things like remote controls.

    It is used by penetration testers (information security professionals) to do myriad kinds of legit, legal work in their field.

    Like any tool it can be used for good or evil. The problem isn’t the tool but the vulnerabilities in cars demonstrating shocking negligence on the part of manufacturers.

    Banning the tools just gives us a false sense of security. The vulnerability still exists. It isn’t that difficult for someone to either get the tool, reproduce the tool, or make a new tool with existing parts. Meanwhile law abiding people cannot find the vulnerabilities as easily.

    This mostly only serves to penalize a smallish company and protect large car manufacturers from the consequences of their negligence.

    It is already illegal to steal cars. Why would criminals risking felony jail time care about whether their tools are suddenly illegal, too?



  • Fundamentally we as a species have lost the use of face and voice in a video to establish authenticity.

    A person can spoof an email, and we have cryptographic signatures as a means of authentication.

    So if I record myself saying something I could sign the video I guess (implementation TBD lol).

    But what if someone else (news agency say) takes a video of someone else, how do we authenticate that?

    If it’s a news agency they could sign it. Great.

    But then we have the problem of incentives, too. Does the benefit of a fake outweigh the detrimental effects for said news agency?

    The most damage would be to the person being videoed (reputation, loss of election, whatever). There would be less damage to the media company (“oops so sorry please stay subscribed”). You could add fines but corporate oversight is weak. And the benefit of releasing a fake would be clicks and money so a news company would be a lot more likely to pass along a fake as real.

    So I guess I have no idea what we do. At the moment we are fucked. Yay.





  • I wonder if we will hear the outcome of the lawsuit or if it will just get settled out of court.

    “the gangs knew that Google Maps sent unsuspecting tourists driving rental cars” along it, the lawsuit alleged, according to Mercury News.

    The company finally agreed to stop Google Maps from directing people through the area albeit three weeks after the attack, which prompted the couple to seek unspecificed damages.

    On the one hand yes there are high crime areas and this is one.

    On the other hand, it is possible that Google routed them stupidly.

    On the other hand people shouldn’t be traveling without learning a bit about the local threats and how to stay safe.

    But crime is ultimately the responsibility of governments and they also have some responsibility to tourists.
