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.

You can get tiny rubber hands that each go onto one of your fingers. There are lots of vendors that sell these on Amazon, and presumably many other places. Different skin colors exist.

I’ve also seen even tininer ones that you can put on the first set of hands, so maybe you can find those as well.

This is super cool and looks quite polished in the video. It’s awesome that we live in an era where it’s possible for one guy to create this as a solo hobby project. Too bad it’s Android only but that’s a me problem.

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that has already been performed or published prior to our receipt of your request will not be reversed, undone, or withdrawn.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.

Well I’m already here, and clearly I chose sh.itjust.works. But my point is that for a lemmy (or any fediverse) newcomer it’s a little daunting and that added friction slows adoption.

Oh that’s interesting. Twitter never interested me, and I’ve never created a mastodon account either. I guess it makes sense that the best way to write a long post when microblogging is in a macroblog and then link sharing. Seems like massive irony there, highlighting the funny nature of microblogging.

That kind of verified identity management for particular users would be great!

The collective of federated servers is still a huge impediment to public growth, since Lemmy isn’t just one thing, and I expect it will continue to hamper growth here for a long time, as new users are confused about how to choose a home base.

I started out with local forums on 2400–9600 baud dial up BBSes with banks of only maybe half a dozen modems for simultaneous use, run by self-funded hobbyists (who has the time and knowledge for that?). Pre-internet, if you will, although really internet did exist then, just primarily with academic and DARPA users and not public ISPs. The pinnacle of software evolution there was MajorMUD (on MajorBBS), with great adventures and full ANSI-colored text and ASCII art, but the local forms were fun too. We even had an occasional IRL picnic since everyone was within a reasonable area (not to have long-distance phone charges). But it meant the niche topics were few and far between, lacking a sufficiently broad user base (hello Lemmy!).

Boy I really hated the mess of forums you described as one of the golden eras. It wasn’t just the fractured identity management. BBcode was functional, but damned ugly, and difficult to navigate.

I hope you’re right about the future. Reddit was far and away the best forum discussion ground I had ever used, until it wasn’t anymore. I particularly like the idea mentioned in another comment of a future where (journalism, academic, professional, etc.) organizations might provide identity services in the fediverse and we could interact with either known or anonymous users. Bots and AI training are ugly issues you don’t address at all though.

I’m curious to hear your thoughts about publishing a post like that on your blog and then publishing a link to it here in the fediverse. Obviously you expect the discussion to occur here rather than in the curiously-still-enabled Wordpress comments. Would it be better to post the original content on Lemmy, but you still feel tied to Wordpress and having an RSS feed? Does Lemmy still feel like an experiment that might end whereas the blog is more still your own content repository?

Meta: I’ve noticed a lot of VOA links on Lemmy lately, and I’d like to understand why. As I understand it, VOA is essentially a national propaganda news organization targeting an international audience (similar to RT). Why is that a good source for article sharing? Especially in the case of the article at hand, which is just a VOA republication of an Associated Press piece that could have been linked originally.

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.

Finish in a day isn’t a great requirement to put alongside “best ever”, as others have already covered. That aside, check out The Pillars of the Earth by Ken Follett. You’ll be surprised by how fun it is to learn about medieval technology development and stone cathedral building techniques when it’s all wrapped up in a gripping narrative.

I got some that were nicely finished bamboo but they didn’t have enough of a sharp edge at the business end to really give a good scratch like the ones from my youth. Fortunately that was easily rectified with a couple seconds on a belt sander.
