  • [announcement] this is officially the worst Lemmy app (at least for Markdown rendering)

    Jump

  • Just carry on. I did not know your app existed (I am on iOS), and would question the decision to put your real name in the repo. But markdown support is hardly the most important part of a Lemmy app.

    Sure, spoiler tags are nice sometimes , footnotes I don’t care about. And my app of choice, voyager (after memmy died off), only recently added support for spoiler tags.

    Keep going. The fediverse needs variety.

  • Dark oxygen made by deep sea 'batteries'

    Jump

  • The reason I questioned the literal battery theory / electrolysis is based on this quote from the BBC article The scientists worked out that the metal nodules are able to make oxygen precisely because they act like batteries. I have since found the original research paper (i linked it elsewhere in this post) which suggests the authors did not actually say that and aren’t sure of the exact mechanism. Your ‘voltage potential grabbing polar ends’ is not one on the known methods of splitting water into oxygen and hydrogen (see wikipedia, which all require electricity, light, radiation or extreme heat. None of which seem to apply here, and the paper also does not mention hydrogen being produced. So maybe there isn’t water being split here by these nodules

  • Taking a test lol no, way too old for that. But while these lumps of metal in sea water may generate some electricity, I can’t see them magically lining up in series like in a 9V battery, and below a certain voltage (1.5) there is no electrolysis - not even a little bit. But I have since found the original article and raw data, and it seems the people that wrote it don’t know either exactly how this oxygen is created.

  • What seems to be the original study:

    https://www.nature.com/articles/s41561-024-01480-8#Sec14

    TLDR, they aren’t sure where the (small amounts) of oxygen comes from. And while the article is full of numbers, the section on measuring voltage from these lumps does not contain any. The raw data suggests (to me as a non expert) that the voltages measured are way too low for electrolysis of water (which requires >1.5V)

  • Electrolysis requires an electric current, so energy. What I don’t understand from this article is where that energy is coming from. Magnets have nothing to do with it, they don’t produce energy. Batteries do, and different metals in salt water may act as a battery, but then they get used up in the process.

  • I’m not sure what you are getting at. Apple offer storage and offer to encrypt that storage. You think that should be illegal? What about Apple offering storage and I encrypt stuff myself before storing it? What about a self storage company where I hire a container and put my own padlock on it? Or the self storage company has a duplicate key, but then I store a locked safe in it? And even if you could get Apple to change their ways: what about Amazon cloud storage - a lot of companies and agencies would be very unhappy if Amazon could scan their data. CSAM is a problem. But abandoning all privacy and security is not the solution.

  • Obviously, they need to be monitored is a flawed view. Obviously, you want all your mail to be checked, all your phone calls to be recorded?

    Obviously, most of us would like the producers of CSAM, and the people spreading it, to be held to account. But arguing that if we could just monitor these platforms we would reduce the problem is not credible.

  • Any evidence that Apple use everything I store in iCloud for training their AI? Please share your evidence. There is a long list of things I don’t like about Apple, but their views on privacy are not on that list.

  • You are missing the point here that from a privacy point of view, Apple should not have the ability to see what I store on my phone, or by extension on iCloud. Just like the company that made my TV has zero business knowing what I watch on that TV.

  • There is no ‘good’ way of monitoring these platforms without a massive intrusion of privacy. Just like there is no good way of monitoring what people store on their hard disks, memory sticks, or burn onto dvd/cd and send through the mail.

  • Being up to date is the entire point

    No, it isn’t. The point is to keep systems safe and operational. Blindly rolling out untested updates is not a good strategy for that. I have seen entire systems shut down due to false alerts from updated antivirus software. Luckily only test environments, before these updates were rolled out to production. It does not take much to test updates like this before rolling them out to your entire organisation.
