  • VMix popularity exploded during the pandemic. A lot of conferences became a blend of teams/zoom/Google and VMix.

    Might be hardware based like a multi-m/e video mixer (blackmagic make cheap ones), or maybe more of a screen manager (like barco e2, analog way livecore). But, unless there are production requirements, vmix is much more likely. It’s (now) proven, and much cheaper!

    OBS can absolutely do it. There are other open source softwares that can do it.
    I’ve seen people bastardise Resolume into something that looks decent.
    There are some online studio systems so everything you do is virtualized. Streamyard used to be like this, till it was bought by hopin (I think it was hopin)


  • You can do reverse proxy on the VPS and use SNI routing (because the requested domain is in clear text over HTTPS), then use Proxy Protocol to attach the real source IP to the TCP packets.
    This way, you don’t have to terminate HTTPS on the VPS, and you can load balance between a couple wireguard peers so you have redundancy (or direct them to different reverse proxies or whatever).
    On your home servers, you will need an additional frontend(s) that accepts Proxy Protocol from the VPS (as Proxy Protocol packets aren’t standard HTTP/S packets, so standard HTTPS reverse proxies will drop them as unknown/broken/etc).
    This way, your home reverse proxy knows the original IP and can attach it to the decrypted http requests as x-forward-for. Or you can do ACLs based on original client IP. Or whatever.

    I haven’t found a way to get a firewall that pays attention to Proxy Protocol TCP headers, but I haven’t found that to really be an issue. I don’t really have a use case







  • But it is a fixed ratio.
    If it was in pounds, metric tons, moles or atomic mass units… It doesn’t change the ratio, the actual number.

    Would it be acceptable to drop the unit all together?
    “Lethal dose is 0.000000012 : 1 (substance : bodyweight)” (I made up the number).
    I’m not sure if there is a better way of writing the ratio.

    Could a fraction be more applicable?
    “lethal dose is 1/600000 of bodyweight”

    I’m sure it’s written as ng/kg to show the base units are the same, and the rest is just “fiddling” scientific notation










  • I’m saying it’s false to apply Occam’s razor to this scenario and draw a conclusion that this is caused by non-human life.

    I’m not assuming earth is unique. There have been many earth-like planets that have been discovered.
    I’m not even assuming humans are unique, given all of space-time.

    It is extremely unlikely that there exists intelligent life other than humans at this time (or within the window-function of time required for us to receive a transmission from however many million lightyears).
    Like, it is vanishingly small. The insane series of events that has lead to an intelligent species being dominant on a planet is ridiculous, to be honest.
    In other words, humans are essentially unique at this point in “observable” time.

    It is extremely likely it is a natural phenomena that we don’t understand, or even equipment malfunction, misinterpretation, miscalculation etc.
    We have discovered unknown signals, then learnt what they are. Humans don’t know everything.
    We have discovered unknown signals, then realised it was a nearby microwave, or a dodgy connection, or whatever. Humans make mistakes.

    The simplest explanation in order to not have to deal with a new research project is probably “aliens”. But the simplest explanation is “natural phenomena we don’t understand yet”
