I have seen Urbit a couple times but never really understood it. From the "Understanding Urbit" page - >Imagine that you can login from anywhere with one name and password. >And when you do, your entire OS appears. >Inside is your whole digital life. All of your communities, conversations, and connections. All of your biometric data and devices. Your entire personal archive in one place that’s secure, private, and designed to last forever. What does this mean? My whole digital life? It sounds like I'm signing in to a VPS from which I access all of my digital life. Is that it? Do I get a VPS? That seems kind of like what I'm getting. The first line on urbit.org is "Urbit is your last computer" - but I don't see how I'm buying a computer, for a one time fee, for life, without paying a ton of money. I see this website [1] has an Urbit "Planet" available for .04 ETH, or about 6 USD. Could I get a life long VPS for 6 dollars? If so, I'd definitely be up for it. If not, what, exactly am I getting for 6 dollars? The page "Understanding Urbit" also says that Urbit OS "can never show you ads". What does that even mean? It can't run Chrome? The OS can't show ads? Any image or text can be an ad. I don't get it. What I would like to see is a simple explanation of what Urbit is. Maybe a video, where someone logs in to Urbit, and interacts with it in someway, doing something that can't easily be done in some other way. I'd like to know the difference between planets, stars, and galaxies. There has to be a better way to explain this. 1 - https://opensea.io/assets/0x6ac07b7c4601b5ce11de8dfe6335b871c7c4dd4d/4738720 https://opensea.io/assets/0x6ac07b7c4601b5ce11de8dfe6335b871...

Urbit is an overlay OS, a functional VM you can run that does strictly typed p2p networking with other urbits. So, it’s software you run on your computer or on a VPS. The thing you’re looking at buying is the Urbit equivalent of a domain name. You can read more about the design decisions in their PKI blog post. (Most recent one, I think)

  Is an overlay OS a program that runs on another OS?
  - belisarius222 7y ago
    Yes. Not exactly a standard term, but there is no standard term for what Urbit is. It's VM, personal server, yes -- but those don't clearly convey the scope of the project.
    - iudqnolq 7y ago
      How is it a personal server if I need a personal server to run it? Am I buying compute power on other people's computers? Also, why call it an OS if it doesn't replace existing ones?

        It’s a personal server OS. MS-DOS was emulated on mainframes before it was run directly on hardware. Urbit wants to do the same, starting by being emulated on traditional computer OSes, and eventually moving to bare metal.
        iudqnolq 7y ago
        What's a personal server OS? Will I use it to write text documents and browse the web? Can I run the X Windowing system on it? It appears to me it's currently accessed through a browser. Is that temporary?
        miss_haru 7y ago
        The primary way you access any web server is through a browser. You can access your Urbit server by command line, or by web interface.
        iudqnolq 7y ago
        Ah. I assumed a Server OS was an OS to run servers, not a server that exposes an OS. Thanks for the clarification!

The part you buy is dns that runs on ethereum (iirc), but with artificial scarcity because they want to make money. This part is completely pointless, because the actual system could work as well on ens directly, or even dns. The actual urbit is like docker with standard API for communication between all apps on different containers, but it runs on a lisp-machine like architecture, except instead of lisp there's a new esoteric language called Hoon. If not for the scammy wealth extraction attempt with the name system, I would consider it to be in the same general category as TempleOS - a form of art.
- bronzejaguar 7y ago
  Funny, because Urbit’s address space has been around for longer than ENS, and makes different design tradeoffs than DNS. https://urbit.org/blog/pki-maze/ https://urbit.org/blog/pki-maze/

  That's a bit cynical, I think. The address space has had a few "official" rationales because it serves a handful of duties at the same time; again, explaining a system is different than explaining a product, but pitching a system as a product is difficult. You often end up framing the system-as-product a specific way each time. > Urbit is a friendly network: a network on which you can assume that a stranger is nice until proven nasty. Friendliness is a direct consequence of scarce, individually owned identities. We're not changing human nature, just creating the right economic incentives. > Most forms of network abuse are "Sybil attacks": they rely on an infinite supply of fresh identities. Scarcity makes reputation work. Spam is a business; if the cost of a new planet exceeds the amount of money you can make by spamming from that planet until its reputation is trashed, there will be no spam. [1] While it's true an intent was selling the parts of the address space Tlon has to fund its development, its business model for consumers going forward isn't really to sell you planets; it's more about bootstrapping the project and offering hosting and support. For investors, purchasing address space (i.e. a galaxy or star within Tlon's ownership) is a way of investing in an asset that could be a source of income while also having some influence over how the network changes in the future, in the way a stockholder would a company. Essentially the address space is an attempt to create and maintain ideal incentives for the ICANN-esque players (galaxies), down to the ISP-esque players (stars) and the everyday user (planets), and their devices or additional users (moons) in a way that sustains the entire network.

Urbit “planet” is like a VM, but running an OS developed completely independently from existing computing words. There is a custom language, a custom network layer, a custom cryptography and custom identity system. There are even custom words for common terms. This has no GUI, but it does has a web interface that you can connect to. From the practical standpoint, you have a linux process running from a data directory. You run it, and the you can access it via CLI and via web interface (which also has a terminal-like webapp). It then uses regular IP to talk to other urbits in P2P fashion. From what I could find, the whole thing is full of magic and pretty opaque - you are only supposed to interact with it by running it and typing commands there. In particular, you’d probably want to back it up. The only instructions I could find is to stop it and tar it up, and back up manually. Better do it often if you want your “digital life” to be safe.

  > custom cryptography Just lost me. > you are only supposed to interact with it by running it and typing commands So, "the last computer you'll ever need" ... other than my phone, because the last time I wanted to type commands on a phone-sized device, was back when I was wet-dreaming over the Sharp Zaurus.

  - bronzejaguar 7y ago
    As far as I’m aware, there is no custom cryptography, and you can interact with it through a web UI now, not just through commands. Not sure where they got that idea.

Here is one example: [0] > This raw interface is vaguely modeled on the haskell aos-signature package, but is written in terms of ed25519 primitives instead of general ECC and changes how linkage tags are computed... Re command line: I was based it off the public docs. Go to "https://urbit.org" https://urbit.org", click on "install". The very end of the instructions say: > Type (add 2 2) into the Dojo.

  This is a pretty strong statement. Can you provide details to back it up? I’m interested because Urbit seems at the edge of genius that is ahead of its time and obscure and inaccessible. The hoon programming language seem quite ambitious.
  - lisper 7y ago
    The obscurity and inaccessibility are classic cult tactics. The obscurity and inaccessibility and weird terminology is not there to provide functionality, it's there solely to mislead, to make it appear that there's something deep and mysterious going on that only the elect and enlightened can access. (They even admit as much: "Hoon, for the most part, is weird by design...") If you actually dig into the technical details (and yes, I did) you will find that there is no there there. In point of fact, the functional parts of the system are all really written in C (pieces of code which in Urbit-speak are called Jets, again in an effort to obscure the underlying truth). Other items of evidence: 1. Urbit was founded by Curtis Yarvin, who writes a blog under the pseudonym Mencius Moldbug. He espouses an extreme right-wing Ayn-Randian political philosophy. Go look him up and read some of his writing (he's quite prolific) and see for yourself. I suggest starting with [1]. 2. Urbit makes extreme and unjustified claims about itself. The very first sentence on the web site is (as I write this) "Urbit is your last computer." Well, no, it's not. It's not even a computer at all. It's software. It's a badly designed, badly written, badly documented federated social network. And that's pretty much all it is. 3. Buried deep inside Urbit is a scam to take your money. The scam is quite well hidden, but it's pretty obvious once your attention is drawn to it. Part of the Urbit design is an address space analogous to IP addresses. The Urbit people call this address space "real estate" and they call Urbit "the biggest real estate platform in the world" [2]. They claim that these addresses have value because they are scarce [3]. Except that they aren't. The Urbit address space is 128 bits wide, meaning that there are vastly more Urbit addresses than there are elementary particles in the universe. But this fact is conveniently obscured in their documentation. If you want what Urbit claims to provide, a computer that you control, just get a Linux machine. Gnu/Linux has its own political baggage attached to it, but it's not a scam. It has its obscure bits, but that obscurity is rooted in history rather than a deliberate attempt to mislead. --- [1] https://www.unqualified-reservations.org/2008/11/patchwork-positive-vision-part-1/ https://www.unqualified-reservations.org/2008/11/patchwork-p...

As with basically every distributed or 'cloud' system that claims to provide a solution to storing peoples data, my first question is always "What if my data is in excess of 100TB?" Someone has to have some hardware somewhere that's storing that much data, and it's not cheap to acquire, maintain, or operate that hardware. So if they're claiming I just don't need to worry about data storage any more... I'm going to worry.

> The page "Understanding Urbit" also says that Urbit OS "can never show you ads". I don't understand this dogma that "ads = bad". At most, they're an annoyance. Not evil. They can influence purchases, but the final act of consumption is solely the individual's. They're an easy target, but attacking them distracts from the much larger problem of government data collection and censorship.
