  • Measured voltage is completely dependent on what is used as a reference. If you were to measure the voltage of a power supply set to +30V with a voltmeter whose leads were backwards (ie positive on the voltmeter connected to negative on the power supply, and negative connected to positive), then you would measure -30V. All this is to say that if you connect your 30V supply “backwards”, you will have -30V. Now, there may be some circuitry in the power supply that only allows current in one direction, and it could be that it’s able to source a different amount of current than it’s able to sink, so be sure to check its manual.

    I’ve tried -12V from psu i’ve got lying around but it didn’t work.

    I’d advise caution against arbitrary decisions with electronics — both for your own safety and the safety of the equipment.












  • Even if the police were functioning well enough to act to stop a school shooter, there is still the issue of time — it takes time to arrive to the scene to respond to the threat. A competent on-site security presence would be a good first line of defense. Think of a time sensitive scenario like a home invasion — would you rather have the means to immediately protect your home, or would you rather wait for the police to arrive? What if someone attacks you on the street? Would you rather have the means to immediately protect yourself, or would you rather wait for police to arrive? In some cases, no matter how competent the law enforcement is, it’s simply impossible for them to respond fast enough.










  • It’s breaking the stated aim of open federation by tampering with comments, posts and mod records, which in turn get propagated or de-propagated to connected instances, right?

    I’m not convinced that this is in conflict with the aim of federation. The whole point is to give people the power to create their own instances with their own rules instead of having to rely on a single central authority. The network isn’t necessarily distributed — it’s decentralized. An instance can administrate their content as they see fit. An instance cannot alter the content produced by any other instance. An instance can only manage the content originating from itself.


    but 1) one instance (particular a significant one like ML) affects other instances

    Would you mind being more specific?


    they’re breaking the spirit of their own software by shamelessly abusing admin powers, in turn helping to normalize that behavior to the Lemmy side of the FV.

    Hm, well, it depends on your perspective. The whole point of the Fediverse is to give people the freedom and power to control how they interact with the service. A server has the freedom to associate with the users that they wish in the same way that you have the freedom to consume what you wish. The spirit of the software is to enable people to have this freedom that otherwise wouldn’t exist with a large central service. The way I like to look at the Fediverse is where each instance is like a country, and each community is like a regional/state/provincial government within the country, and federation between instances is like cross-border policies between nations.


    a supposedly transparent […] social network?

    I’m not sure what you mean by “transparent”.


    a supposedly […] user-run […] social network?

    It is user-run, in that any user can create an instance.


    a supposedly […] P2P social network?

    It’s not P2P. A P2P network would be distributed. The Fediverse is decentralized.
