  • 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.







  • If the rise time isn’t 0, it’s not a square wave.

    And if that’s your definition then there’s no such thing as a real square wave.

    Just like no physical objects can have a perfectly square corner, there will always be some radius, even if it’s just 1 atom

    The reason making a true square wave is hard is that there are physical properties of real life electrical components that prevent voltage (or current) from changing instantly. Similar to how we can’t instantly accelerate a mass from 0 to some speed, it’s physically impossible. The faster you try to do it, the harder it is due to inertia. In electronics, there’s always natural capacitance and inductance slowing things down. If you want a 10v square wave, you have to push some amount of electrons through some amount of capacitance and inductance and that, while it can be very fast, is never instant.

    Lmao idk if “most” even holds up in fiction. Even the “good” cops in fiction tend to perform illegal searches, abuse suspects, break the law in countless ways to get the bad guys. How many times have we seen the “good guys” stymied by their inability to search a home but one turns to the other and sarcastically says “oh I think I heard someone scream for help lol” kicks down the door?

    Sometimes they have a conscience but I’d call very few fictional cops “good”




  • This gets posted occasionally and while I agree, the subscription for an airbag is one of the dumbest things ever, it’s not the only way to buy the thing.

    It’s available as a one-time purchase instead, which obviously is what everyone here would choose, but it’s a fairly high price, and their argument for offering a subscription model is that they want the price barrier for safety equipment to be lower. There are other ways to do it, but the option of a subscription is fine IMO as long as the one time purchase remains as well.



  • Personal preference: Jellyfin instead of plex

    Some that I run that you don’t seem to have anything for:

    • Lancache (if you have several gaming PCs on the network or host any kind of lan party)
    • surveillance camera software e.g. shinobi
    • I see grafana, but other monitoring services like icinga, librenms, etc
    • Mayan EDMS - I’ve found this really helpful as anything I get in the mail, I scan in, and this makes it all searchable and retrievable.
    • There’s a whole hole you could dig if you start getting into home automation (I use home assistant)
