  • The way this works in the server world is “95th percentile” billing. They track your bandwidth usage over the course of the month (probably in 5 minute intervals), strike off the 5% highest peaks, and your bill for the month is based on the highest usage remaining.

    That’s considerably more honest than charging you based solely on the highest usage you could theoretically use at any time point in a 24 hour period (which is how ISPs define the “max bandwidth”) and then charging you again or cutting off your service if you use more than a certain amount they won’t even put in writing.



  • Probably not. It looks like it’s setting the fake address before reading the tunnel parameters, where the real address is stored. Probably a kludge in case the connection address is undefined so the program doesn’t crash. So check whether the address is included there.

    Also check the function that establishes the connection. 10.1.1.1 is not a public subnet, so unless there is a VPN device listening at the local address, the tunnel should fail to establish and throw an error, triggering the exception clause in that code. Again, you’ll want to confirm that in the code.




  • Manually keying in the pin is only needed when plugging in the device. Challenges for TOTP, FIDO2, etc. are a configuration option, and are only 3 digits if enabled (press any button if disabled).

    As for “excessive amount of security”, security as an absolute measure isn’t a great way to think about it. Use case and threat model are more apt.

    For use case, I’ll point out it’s also a PGP and SSH device, where there is no third party server applying the first factor (something you know) and needs to apply both factors on device.

    For threat model, I’ll give the example of an activist who is arrested. If their e-mail provider is in the country, they can compel the provider to give them access, allowing them to reset passwords on other more secure services hosted outside the country. The police now have the second factor (something you have), but can’t use it because it’s locked.









  • literally no one will ever have that problem, but lets humor your ridiculous made up bullshit

    Wow, your username really fits.

    Actually, it’s a description of some of the issues I’m dealing with right now. And yes, we’re DIYing it with RJ45 wired switching outlets on a separate vlan and subnet. And yes, we use a chest freezer.

    And yes, there are more automatic and passive ways to do some of these things, like planting deciduous trees to shade your south wall in summer but not winter. Not everyone owns their home and land though.


  • There are problems they can actually solve, mostly heating and power related:

    • In summer, lower the blinds on south facing windows when the sun comes up to reduce solar heating, then raise them in the evening to increase air flow against the window panes. This reduces the need for air conditioning, resulting in a surprising amount of power saved.

    • On a home solar system, start the washing machine, dishwasher, and dryer that were loaded in the morning when the batteries reach 80% charge. Allow them to run off the inverter rather than taking the charge/discharge losses involved in battery storage, reducing the size of both battery bank and solar array needed.

    • Lower the freezer temperature when there is a power surplus, and raise it back to normal when not so that cooling energy is used when it’s cheapest/most available

    If you don’t work from home, you can’t do the second two yourself. They require automation. Reducing baseload requirements and battery storage needs can make a transition to renewable power much cheaper and more efficient. With mass adoption, that extends to power grids and not just off-grid homes, and has significant effects on things like the amount of lithium that needs to be mined or the number of coal and LNG power plants that are needed for times that are off-peak for wind and solar generation.
