  • The US dollar technically isn’t backed by anything either

    No, it is. it’s not “hard backed” by X dollars to Y grams of gold, but it absolutely is backed in the sense that McDonalds (and hundreds of other companies) does it’s accounting in USD and will continue to do so for the foreseeable future and doesn’t expect wild fluctuations in ingredient prices or wages and wants to prevent those from fluctuating, because when that happens, their business math gets harder.

    You can go outside the door with 100$ in your pocket, vanish for 3 months, come back and it’ll still be usable to buy food, a hotel room or a transportation ticket.


  • Not much to say. I’m glad one more person got out.

    Crypto is still an interesting concept. Maybe not the exact same way that bitcoin does it, but nevermind that. The problem with bitcoin is, was and probably will be, that it is not actually materially backed by anything. Could be real estate, could be agriculture, could be some kind of industry that says, you can always get our product for exactly _______ many bitcoins and we change prices every 6-24 months.

    Doing it doesn’t make sense because it would drastically over or undervalue the thing and without that kind of backing the currencies will never stabilize enough to be useful.

    The concept of having a single mathematically verifiable, unchangeable record of ownership that doesn’t depend on a nation state is still theoretically useful and interesting though. But obviously none of the current implementations are all that useful. Or they would have “won” by now.


  • Oh yeah. My favorite (and only) plugin so far is the https://github.com/twibiral/obsidian-execute-code

    Let me explain: Obsidian is basically a very fancy wrapper around a folder with markdown files in it. (which makes it git compatible, which is one of the upsides). In Markdown, you can define codeblocks, with syntax highlighting, because of course you can, programmers will improve their own tools first. Now, there are two cases when you would do this:

    1. you want to execute the code because it’s actually driving something. Like some kind of interactive, “this is the manual, but also, you can just do it right away by executing this code” and then they give you the code.
    2. you’re actually building it as a document, and you want something in your document that is actually the output of some program that’s producing some output. Like… analyzing numbers and creating a graph. You can now just put the code in the document, hit “execute” and you get your output in the document right then and there. And that concept isn’t new, it’s what “jupyter” also does, but jupyter uses a weird bytecode, xml zip format or something, in obisidian, because of the markdown base, it stays just code. (which again, makes it git compatible where jupyter isn’t) AND you can do it not just with python but with…

  • I don’t really get it,

    Sticking with the snail mail analogy, what happens when two pen pals keep sending mail to each other from their homes without including return addresses in their envelopes? The postal service might not know who exactly is sending each piece of mail but, over time, they would know that Address A in Lower Manhattan, New York, keeps on getting one-way mail from the post office in 3630 East Tremont Avenue, the Bronx, New York; and Address B in the Bronx keeps on getting one-way mail from the post office in 350 Canal Street, Lower Manhattan.

    I mean, no, all they know is that they ALL users get one way mail all the time?

    The “over time” in “but, over time, they would know that…” does a lot of heavy lifting. Would they? How would they know that?

    Sure, if there were only two participants in the system, I would agree. But we have way more than 2 users on signal.
