  • There was an episode of The Outer Limits (7x08 Think Like a Dinosaur) that dealt with this exact question.

    In that episode, humans are maybe-given a teleportation tech that creates a perfect copy somewhere else, but the aliens need to trust that we will ‘balance the equation’ (destroy the original) every time. That’s easy when the human in question is immobilized for transfer. Only one transfer goes wrong- the person being transferred is woken up before the transfer is confirmed, and then the transfer gets confirmed. So now you have the original human, who’s already been copied, and the transfer operator still has to ‘balance the equation’…


  • I assume by “Raspberry Z-Wave module” you mean the RaZberry z-wave addon board, and I couldn’t agree more. I tried to get that thing going with another home automation package and gave up after a few hours of fucking with it.

    That said, these days I’m using Home Assistant on a RPi with a Nortek z-wave/zigbee combo radio USB interface and I couldn’t be happier. If you’ve never used HA it’s worth trying out; used to require a lot of scripting but now it’s a beautiful and polished system that has all the tweakability a nerd wants with a nice high-WAF GUI. They have a plugin that does exactly what you’re doing and makes a virtual alarm system out of existing sensors.

    I also agree block connections and use a VPN to access it, I do the same thing.




  • That was a fairly famous situation. The reporter was very anti-EV, and trashed the car’s crappy range and said it ran out of power on him with no warning.
    Tesla released the logs showing that it popped up low power warnings and suggested places to charge several times, all of which were ignored. When the car reported 0% it was then driven to a parking lot where it drove around in circles (the whole time, suggesting a nearby charger) until it finally shut down.
    The reporter was then fired.


  • I’ve been saying this for a long time.

    There are use cases for the cloud. I put e-mail in the cloud- ain’t nobody got time to deal with providing reliable SMTP or Exchange while keeping spam out. If you have a web app that needs to scale quickly, cloud’s the way. If you’re a startup with limited capital and you don’t want to blow it on a bunch of servers when you’re not sure if you’ll survive more than a year or so, cloud’s the way.

    But Cloud ISN’T the end-all answer for everything.

    If you have a predictable workload, especially one that relies on more expensive cloud services, de-clouding can save you a bundle. Buying hardware can be cheaper than renting it, if only because (think about it) the cloud provider has to buy the same hardware and rent it to you AND make a profit. If you’re going to be around a while, and you expect to use a piece of hardware for its full service life, that makes a lot of sense.



  • So would a router running pfsense then also become my primary WiFi routers too? Or is it best to keep pfsense strictly as a firewall and have a separate router strictly for WiFi?

    pfSense doesn’t really do WiFi. So you’d use it as a router/firewall, then have something else do your WiFi. I generally recommend Ubiquiti.

    It’s worth noting that a ‘WiFi router’ is usually 3 separate things in one box- a router/firewall, a WiFi access point, and a small switch of usually 4-6 ports. In a home you usually want these things in the same place so they’re in one box. In an enterprise, the router/firewall is usually in the basement where there’s no WiFi, network switches may be in many places and a tiny one in the router won’t help you, and WiFi is up by where the workers are. So it’s that sort of setup that pfSense is designed for.

    The way I have my place set up- a pfSense machine is the router/firewall. I then use Netgear managed switches (there’s a few, mainly GS110TP’s), and Ubiquiti WiFi. The Ubiquiti controller runs inside Docker on a small Synology box. Highly recommend this setup.

    But I’d just as highly recommend going Ubiquiti all the way. Dream Machine Pro SE is a great base router/firewall, and it has a built in PoE switch so you can hang a few U6 Pro access points off it. You get a bit more flexibility with pfSense but in most home environments it’s not needed.



  • Routers - Netgate / pfSense. Best router GUI I’ve found. If you understand what you want to make happen, chances are you can figure out how to make it happen without touching a CLI. And generally free of Cisco for license bullshit.

    Routing and WiFi- Ubiquiti. Not as flexible as pfSense but even easier to use and if you do both routing and WiFi with them you get a bunch of cool analytics. Their surveillance package is great too as long as you use their cameras, pretty much the best mobile surveillance app I’ve found. Door access system also gets a mention.

    Synology for almost everything they do, but particularly storage, backup, surveillance (they support almost every camera, albeit with a license requirement) and hosting of self hosted apps using a nice docker GUI. Not as much bang for buck vs. an old PC in terms of CPU power, but very easy to use.

    For home automation- Home Assistant or HomeSeer. Both are open platforms that support almost everything. Home Assistant pulls lightly ahead for me because it’s free and has more 3rd party integrations, even if it has a steeper hearing curve in some areas and some rough edges that require tweaking for basic usability (specifically, Z-Wave requires the ‘z-wave js ui’ plugin to take real control over a Z-Wave mesh, and Z-Wave door locks need the Keymaster plugin to get any sort of user code management, neither are straightforward to install). That said- pair Home Assistant with a Z-Wave dongle and some Inovelli light switches and you have a really beautiful setup with insane flexibility.
