Ironically, the St. Louis hacker who first suggested urbit would be a great fit for Strange Loop (hi Justin!) is an African-American. An obsession with collective identity and collective characteristics - all proletarians are noble, all Ger

"He has literally written that several of his co-speakers are genetically more fit to be slaves while he, a white male, is genetically designed to be a master." Certainly a powerful use of the word literally . Frankly, I'm

Hard-coded into the network layer? Not only is this not true, I can't even imagine how it could be true...

Exactly. An easy way to think about solving the exactly-once problem, on top of an at-least-once message layer, is to use the at-least-once layer to write idempotently (eg, HTTP PUT) into a sequence of numbered messages. There is no possibi

As concisely as possible: IPFS is a way to publish your data in the cloud (and the related Filecoin project is a way to host your cloud data), urbit is a way to publish and host your identity, computing and data. As a more specialized proje

As Dr. Emilio Lizardo once put it... never mind. :-)

If you look below I've made arguments for all these things, but let me try to address them here. Compare ++ add |= [a=@ b=@] ^- @ ?: =(0 a) b $(a (dec a), b +(b)) to attribute add { function(left-

They do - but arguably being forced to define the distinction between direct hierarchical references, and symbolic links, helps constrain your data model and make it more rigorous. Note that relational databases don't have back pointer

That I was keeping my p - never mind. It's amazing how quickly words you know lose their meanings, or rather acquire new and distinct ones, in a functional context. When the iPad was released, I remember distinctly the number of peopl

Don't worry - the test of a system is what it can do. If we were ready to show you what it can do, we'd have released it intentionally instead of unintentionally. It's very difficult for a language, good or bad, to compete o

Nock works perfectly, of course, but it's poorly optimized. The various "jets" (optimized implementations) in our runtime haven't been adequately tested and there are probably a few corner cases, errors, etc, where the

Right. The way I'd put it is: in system software, the iron law is that you don't make the programmer pay for anything she doesn't need to buy. What you pay (GC) for the privilege of having pointer cycles in your data is gros

That's correct. :-)

I resemble this remark. We're making progress more than twice as fast than Xanadu!

Yeah, it's probably not one of our better decisions.

Frankly, it always surprises me that people are willing to randomly run other peoples' C code! It's really quite plausible that I'm just out to steal your Bitcoin wallet. The above are all data structures - not even function

I definitely wouldn't endorse this description - it's a bit secondhand. What I'd say is that Urbit is not designed to be a darknet. It is not Tor and it's not Bitcoin. Also, it is not designed for external governments,

If you s/is/could be/, I would agree. I would say s/is/should not be/. That is, it is possible to screw this up and create "intimacy" (high coupling), but obviously I recommend against it. Put it

Essentially, I'd say most peoples' brains are better at associative memory than they think they are. When you see a digraph like -> or ?: in C, do you think "hyphen greater-than" or "question-colon"? Your b

I prefer to think of it as: you can be "free as in beer" or "free as in speech," but not both. Sith Lord Zuck has set you free as in beer, but not in speech. Urbit will set you free as in speech, but not as in beer. T

Again, the contributor list in github is WAY misleading, because it accidentally somehow pulled in all the contributors of the libraries we bundled (eg, libuv). We need to fix this, I think.

Yes, some people have made this criticism. We'll be thinking about it.
