  • AV1 and VP9 are likely going to be your highest efficiency “free” codecs. AV1 is the way to go if you mean free as in free open source. It’s not very likely to be implemented in many TVs or set-top-boxes, but VLC/ffmpeg will be able to decode any of these. Webm uses vp8 or VP9 which are “free”(made by Google) but it’s just more specific settings for sharing online/viewing in browser.

    H264/H265 has license fees for non-free software and hardware, but they will be your most widely supported option. H265 is approximately twice as efficient as h264 (meaning you can get the same quality of encode from half the file size).

    Regardless of preset I think you can get handbrake to encode something reasonable from any of these codecs. Especially with DVD video you’ll be able to crank through videos with modern high efficiency codecs


  • It certainly is. ISO 27001 is a framework, not very prescriptive at all. Basically an auditor will ask “how do you ensure data isn’t leaving your facility in the form of discarded hardware?” If you say “here’s a link to our media destruction policy. It says all drives are wiped according to NIST 800-88 cryptographic erasure. If that is not possible or not applicable, the drive is destroyed. Here’s our log of decomissioned equipment” chances are very good they’ll say “OK great let’s move on to the next one” with only minor followup questions.



  • How much do those numbers change when you add the weight of at least one person with everything they own to it? Probably a lot more substantially for the smart car (though it still wouldn’t surprise me that much. People were driving some much heavier and lower powered cars thru the mountains in years past)




  • To answer any of your questions we’d need to know what 7 way plug kit you got. Depending on the type of auto reset it can be minutes before reset, seconds, or it might stay disconnected until power is cycled.

    Frankly I think you’re overblowing the risks in all scenarios here. If you have a short in your brake circuit that blows a breaker, they’re not going to work anyway regardless of what kind of breakers you’re using. Auto reset breakers aren’t going to fry your trucks electronics, nor should a short, because you should also have a sensible fuse on the circuit (unless you hooked up directly to your battery you probably do).








  • Hvdc and a truly global grid brings substantial changes in what you’re saying. With solar energy being extremely cheap, and storage being relatively expensive, even if you have substantial transmission losses, it can be worthwhile to transmit that solar energy. Would a long undersea cable be more effective than huge battery banks? Hard to tell but I don’t think it’s something I’d write off without hard numbers, it’s likely closer than you think
