I was lucky enough that this is how I was taught calculus in high-school. It definitely wasn't easy at the time, but I feel for all the students for whom calculus is taught as a mindless set of algebraic rules. This focus on calculati

The "let" should really be read as "for all". If you do so, your objection disappears since quantifying over the empty always imply the consequent.

Corrolary: solving price stickiness problems, or changes in the demand for liquidity by changing the money supply itself is a horrible hack. All of the (stated) goals of monetary policy can be achieved by using a price index layered on top

So you want to smash the state, then place industries under state ownership?

Nationalize? I believe you mean collectivize, but telling slip.

1) There's still finite volume at a given price, and the arbitrages, when they do happen, typically involve small volumes. 2) There is more to arbitrage than Forex markets

This doesn't take into account available volume. For that you need to solve a min-cost flow algorithm, using for instance the Ford–Fulkerson algorithm.

Our moral intuitions tend to rely on categorical differences.

I think it's because people tend to associate the cabs with the slow speeds involved in the city. I typically don't buckle up in Manhattan, except on the FDR or the West Side Highway, or if we're going above 30 mph. For those

What I mean to say is that the attribute isn't categorical, even though it is treated as such in the discussion. I'm also not saying the regulation cannot "work" by picking a threshold, I am appealing to our moral intuit

Alcor is not a company, it's a nonprofit organization.

In principle, adding more depth to the network can take care of that. If you are keeping track of higher and higher level abstractions, you can remember what you were saying. But you can't remember everything, so ideally you'd als

No, all, including the USD, gold or what have you are subject to P+e attacks. Currencies are consensus, and you can, in theory, bribe a majority of people to turn against that consensus at no cost. So for instance, I could print a lot of bi

One man's modus ponens is another's modus tollens... The way I see it is that there is no such thing as "commercial activity". There is voluntary activity of all sorts, and all kind of transactions happen, whether it be

Do you see a plausible architecture for long term planning? Putting money in my 401(k) every month to get it a few decades from now isn't something that's accessible to Q-learning, direct policy search or forward simulations. How

Note that all currencies are susceptible to these types of attacks. In practice, they are prevented by the massive transaction costs involved.

Why aren't the people who fail to secure their computers liable for the damage they cause if their computer is used in an attack? This should be covered by common law, why does this need regulation?

A RNN can, in particular, implement a GOFAI algorithm. I think that's what we basically learn for the first 5-7 years of our lives by analyzing other people's behavior, communicating, etc.

It balances parentheses and keeps track of other long range dependencies, something markov chain implementations cannot do.

To OCaml in particular, and you're right that immutability does make it much easier, but OCaml has mutable variables, which is precisely why it's hard.

Yes, the threads are green threads: only one can run at a time. There's also an Async framework in Jane Street's Core library and there's LWT. My understanding is that GC is hard with multithread, particularly in a functional

Yes, thanks, sort of! The pattern you use is basically the one I would naturally do, but it doesn't feel "meteoritic"... the client side manipulation of the db really seems centric to the magic of it. Regarding the concurrent

In case you're wondering, there are 8 digits on the one dollar bill serial number, so assuming a random draw by the DJ, the odds of one of the 100,000 dollars matching the draw every day would be very close to 1 in a thousand. After a

by murbard2 11y ago
Thank you, I know that you can do that. My concern is more of a soft question: in practice, in production, isn't that what you always end up doing anyway? And if that's the case, how much of meteor's coolness is lost in the p

It's not cheap and I can't even find a table of content for it. I've also read excerpts that dealt with autopublish etc, and they didn't really address the point I'm making. Is there a benefit to using meteor beyond
626.
by murbard2 11y ago
Sure you remove the autopublish package, but then your app stops working. You need to explicitely publish what you want published, you need to explicitely check and validate every input from the client... and that's fine, but then what

I'm actually looking into meteor at the moment, and the financial backing is a big plus, as it gives me some guarantee that the project will keep being maintained for the foreseeable future. It is indeed a breeze to prototype applicati

Oh I thought the pressure came from the contracting lava as it cooled down, but apparently you're right that's not enough.

I've had the best chars by using a searzall (which attaches to a propane blow torch).

by murbard2 11y ago
Could you just throw in some charcoals in the lava to get diamonds and pay for the whole thing?
