  • I choose not to think about it or include it in my mental threat model, the same way I choose to not worry about thermonuclear warheads.

    If there’s some exploitable backdoor and Intel gets owned, we’re all boned and there’s nothing we can really do about it. I don’t have anti-ballistic-missile systems, and I also don’t have the capability to make an entire hardware/firmware/os from scratch.

    So instead focus on the things you can control and are more likely to happen. Don’t plan for doomsday, plan for every day.




  • Cardiff, Wales. One of the few places in the world that felt like a Real City while also having its own distinct culture and feel. Every other city I’ve been to feels like the same sort of dull corpo-district monoculture.

    Old Montreal also has a bit of this, but only the central city areas, the outside periphery quickly devolves back into the “this could be anywhere in North America (version francaise)”






  • So basically the “conventional” generation methods use a Big Thing spinning at a specific speed to generate AC power. Solar and wind spit out DC which has to be converted to AC and also synchronize to the rest of the grid.

    Hydroelectric, nuclear, coal, methane, all use a big-ass turbine at exactly 60.00 Hz to supply the grid. This is fairly easy to sync, since a change to load or supply will slightly change the physical rotation of the generators. If the load increases, it will draw down the speed of the turbines as it pulls on it harder. When the load is more than the generators can supply, or changes too quickly, it can cause a breaker to flip to prevent damage to the equipment.

    With DC generators, the inverter connected to the grid works differently. It has to sense the frequency changes and react based on “external” factors. Right now there aren’t really widespread protocols to signal this type of grid conditions to solar/wind farms, so they have to be a bit more careful and preemptively disconnect to prevent damaging the inverters.

    So it’s an entirely solvable problem. It just requires the industry (and ERCOT) to be proactive…



  • I’ve been using Thunderbird with the OWL and TBSync plugins for exchange for years with good results. Obviously some things won’t work (teams integration, provisioned signatures, mail merge, etc) but it’s good enough that I only need proper outlook/OWA less than once a month.

    Another option is “installing” the webapp as a PWA. I tried that for a bit but found notifications to be unreliable.



  • Not sure how to do that in docker, I’ve run mine as a plain old PHP-FPM site for years and years. It might be something that can be tweaked using config files or environment variables, or might require building a custom image.

    ClamAV is slow and doesn’t catch the nastiest of malware. Its entire approach is stuck in 2008. It’s better than nothing for screening emails, but for a private file store it won’t help much considering that you’ll already have the files on your system somewhere. And most importantly, it slows down file uploads 10x and increases CPU load substantially. The only good reason to use ClamAV for nextcloud is if you will be sued if you don’t!
