  • Second this, including buying from Costco. I don’t love the Lorex interface, but they’ve been around for a long time and can’t really compete on the modem Ring-style features so they’re now advertising the privacy benefits of their local storage.

    PoE (Power over Ethernet) cameras are the way to go, connecting the camera wires directly to the NVR box, which doesn’t itself need to be connected to your network. The NVR box has a hard drive and an HDMI port. If you do optionally connect it to the network (but just don’t), then their app will facilitate connecting to your box either locally or over the internet so that you can stream your video directly from your hard drive, not their cloud.

    If you want it protected against power outages, you just put the NVR on a UPS and you’re done.

    Of course, if a burglar finds your NVR and takes it, then all of your footage is gone.



  • Why have you never been able to do it? I set up a full mail system years ago on a Xen/Linux VPS with stuff like Postfix, maildrop, Courier IMAP, a custom set of MySQL tables for aliases and such, and at one point migrated my TLS from CACert to LetsEncrypt. I enjoyed some aspects of the huge pain in the ass that all of that was, and having it work nicely was great. Spinning up a new email alias was easy and free, so I created a new one for damn near every site I interacted with, which later turned into a form of lock in having to continue running my server.

    The continual server maintenance was a pain in the ass, requiring me to remember in substantial detail how it all worked so that I could appropriately integrate new things I had to learn like SPF and DMARC. I’m glad to have had some detailed sysadmin experience, but I was so glad in the end to finally migrate away from all that and just pay Fastmail instead.

    I still have nearly the same flexibility with Fastmail and my custom domains, but they’re the ones that need to do all the maintenance. I can’t scale across unlimited domains for the same zero marginal cost, but I can make it work for a reasonable price with a few domains and scale arbitrarily within that. I’m sure there are other hosts out there that do a similarly good job, and Fastmail hasn’t been without its own troubles, but it’s been a net win for me.

    I don’t recommend running your own server. I won’t do it again. I do recommend building an army of custom aliases all at your own custom domain(s).






  • The article is very misleading. It says

    The research paper…notes that the human body is particularly efficient at generating 40 MHz RF energy. Tapping into that through a ‘worn receiver’ provides power without using any invasive means.

    But I read much of the pdf linked at the bottom of that link, and there’s nothing about the human body generating energy at 40MHz. The trick is that skin is pretty effective (sort of) at conducting energy at that frequency, so the authors hooked up a power transmitter worn on the forearm, 5 or 15cm away from a receiver on the hand.

    This isn’t about powering anything by body energy, it’s about strapping a battery-powered transmitter somewhere on your body and then having another device pick it up when strapped somewhere else on your body. No thanks.

    Oh and it’s actually pretty inefficient and won’t provide much usable energy.




  • Also interesting is the language they used in the email they sent me after I requested account/data deletion:

    We received your request to permanently delete your 23andMe account and Personal Information. The following apply when you submit your deletion request:

    • If you chose to consent to 23andMe Research by agreeing to an applicable 23andMe Research consent document, any Research involving your Genetic Information or Self-Reported Information that has already been performed or published prior to our receipt of your request will not be reversed, undone, or withdrawn.
    • Any samples for which you gave consent to be stored (biobanked) will be discarded.
    • 23andMe and the contracted genotyping laboratory will retain your Genetic Information, date of birth, and sex as required for compliance with legal obligations, pursuant to the federal Clinical Laboratory Improvement Amendments of 1988 and California laboratory regulations.
    • 23andMe will retain limited information related to your deletion request, such as your email address and Account Deletion Request Identifier, as necessary to fulfill your request, for the establishment, exercise or defense of legal claims, and as otherwise permitted or required by applicable law.

    The first bullet point makes sense - you agreed and they already published something, so too bad. The second bullet is doing the right thing. But those third and fourth bullets sound like they don’t really have to delete anything, and they’ll keep a bunch of data even if you ask them to trash it. I asked them to trash it anyway.



  • Liquid gels are absolutely faster acting than compressed powder. I buy both generic naproxen pills and name brand Aleve liquid gels so that I have two different available delivery mechanisms (and unit prices) for the same active ingredient, and I choose which to take (or to give my dependents) based on the circumstances at the time of use.




  • They don’t store anything about your association with other numbers; that stays on your devices. Your phone number is used as your identifier for account creation and originally for finding other people to talk with, but the only data Signal keeps associated with your number are registration timestamp and last connection timestamp. You can see that by reading the redacted subpoenas and responses that they publish.

    They have recently introduced usernames so that you can avoid having to share your number to communicate with someone else.

    I don’t have a good citation for this, but I believe the phone number registration requirement will remain indefinitely, likely to cut down on spam and bots. But there’s a difference between privacy and anonymity - I’m looking for privacy in my communications, not anonymity from my friends. State actors can know that you use it but not what you’re saying or to whom (unless, say, the NSA is specifically targeting you, but that compromise will be of your device as a whole rather than breaking Signal or getting data from them).
