Oh wow, thanks. I think at the time I was overconfident that some more educated Bayesian had worked through the details of what I was describing. But the causality-related stuff is definitely covered by Judea Pearl (the Pearl I was referring to) in his book *Causality* (2000).

Looking forward to seeing all of you today! For parking, you can use the street or the neighboring Mother’s Milk Bank. If it’s crowded, try the neighborhood to the west off Justin Ln, but in all cases, watch for signs about where it is legal to park!

Comment by SilasBarta on According to Dale Carnegie, You Can't Win an Argument—and He Has a Point · 2013-12-07T22:28:53.438Z · LW · GW

To your alternative approaches I would also add Bruce Schneier's advice in Cryptographic Engineering, where he talks a little about the human element in dealing with clients. It's similar to the Socratic approach, in that you ask about a possible flaw rather than argue it exists.

Bad: "that doesn't work. Someone can just replay the messages."

Good: "what defenses does this system have against replay attacks?"

Why is a mere statement of contradiction voted up to five? Something I'm missing here? I could understand if it was Clippy and there was some paperclip related subtext that took a minute to "get" but ...

Admittedly no one's ever been charged under the ADA, but there are plenty of examples of people being disciplined for violating it.

Thinking about your experiments does not (in itself) involve expenditure of government money, so I don't see how they would prosecute you under the ADA for that. Yes, managers have to be very clear to workers not to use resources, just to keep them away from edge cases, but even with that level of overcaution, managers can't actually stop you.

Even if you came back and (for some reason) said, "Hey boss, I totally thought about this experiment from the couch when the shutdown was going on", they still don't have grounds unless you were using up resources. Now, they could fire you just for the defiance (maybe), but if they're that trigger-happy in the first place, then ...

Comment by SilasBarta on More "Stupid" Questions · 2013-08-03T21:58:32.638Z · LW · GW

... and that is what being a big fish in a small pond feels like ;-) That is, most of them there won't even make it that far. At least, that was my experience.

(My approach was the cruder one of just taking a remainder modulo max size after each operation.)

Comment by SilasBarta on More "Stupid" Questions · 2013-08-03T18:23:25.641Z · LW · GW

C-style integers = integers with a fixed possible range of values and the corresponding rollover -- that is, if you get a result too big to be stored in that fixed size, it rolls over from the lowest possible value.

Ruby doesn't implement that limitation. It implements integers through Fixnum and Bignum. The latter is unbounded. The former is bounded but (per the linked doc) automatically converted to the latter if it would exceed its bounds.

Even if it did, it's still useful as an exercise: get a class to respond to addition, etc operations the same way that a C integer would. (And still something most participants will have trouble with.)

+1 for a (+1 for acknowledging the inconvenient) on a subject you dislike discussion of.

Comment by SilasBarta on More "Stupid" Questions · 2013-08-01T19:19:07.897Z · LW · GW

Depends on what you intend to get out of it, but you can go to an amateur hack night ("we're going to implement C-style integers in Ruby", "we're going to implement simulated annealing)", where almost everyone but you will have trouble conceptualizing the problem.

Work expands to fill the available time.

Comment by SilasBarta on Does anchoring on deadlines cause procrastination? · 2013-07-18T23:11:40.497Z · LW · GW

It's bad if they're systematically underestimating the urgency (and thus placing the deadline too far out) which seems to be the rule with humans rather than the exception.

Comment by SilasBarta on Prisoner's dilemma tournament results · 2013-07-16T07:58:51.740Z · LW · GW

Maybe we should have a prisoner's dilemma meta-tournament in which we define a tournament-goodness metric and then everyone submits a tournament design that is run using the bot participants in the previous tournament, and then use the rankings of those designs.

Wait: does anyone know a good way to design the meta-tournament?

Comment by SilasBarta on Duller blackmail definitions · 2013-07-16T07:48:05.808Z · LW · GW

Very well said! I would only add that your point generalizes: the differences between the two cases is the extent to which it has implications for future interaction ("moving the Schelling point"): blackmail-like situations are those where we intuit an unfavorable movement of the point (per the blackmailed) while we generally don't have such intuitions in he case of trade.

Comment by SilasBarta on Countess and Baron attempt to define blackmail, fail · 2013-07-16T07:37:43.883Z · LW · GW

Somewhat OT:

Does it really help the exposition to have all the elaborate packaging (the such-and-such vase, the jester and description of the punishment, etc)? For me it just makes it harder to read: is the vase just a perspicuous example of a valuable, or is it important that it's subject to random catastrophe (from errant jesters)? Does the presence of the makeup sex have any relevance that should affect my intuition on this?

But then, a lot of people seem to like that kind of thing, even in non-fiction and when they no longer need explanations via fairy tale metaphors, so perhaps I'm alone on this.

EDIT: Sorry, I missed that you linked a fluff-free version. Much appreciated!

Comment by SilasBarta on Public Service Announcement Collection · 2013-06-29T01:26:27.666Z · LW · GW

Are you saying that no one expected the printing money (bidding up gold) before it happened, or is there a more subtle reason why the only relevant comparison is from the moment the policy called QE started?

Someone who bought gold after the Lehman fiasco (08), but before any of those QE milestones would have had several options since then to redeem for 2-3x gain.

It's an even bigger gap if you compare to any year before, back to ~98. S&P has had a horrible volatility/return performance going back to at least then.

Comment by SilasBarta on Public Service Announcement Collection · 2013-06-28T01:16:27.399Z · LW · GW

Well, it was a pretty safe bet in '08 given typical reactions to economic crises, and the prevalence of advice like this P/S/A that "oh, there totally won't be inflation from the printing money".

Comment by SilasBarta on Public Service Announcement Collection · 2013-06-28T00:03:46.057Z · LW · GW

P/S/A: The people telling you to expect above-trend inflation when the Federal Reserve started printing money a few years back, disagreed with the market forecasts, disagreed with standard economics, turned out to be actually wrong in reality, and were wrong for reasonably fundamental reasons so don't buy gold when they tell you to.

You would have missed out on doubling or tripling your money if you hadn't bought gold when those same people had made the predictions.

Comment by SilasBarta on Is our continued existence evidence that Mutually Assured Destruction worked? · 2013-06-20T01:04:28.930Z · LW · GW

Many treatments of this issue use "observer moments" as a fundamental unit over which the selection occurs, expecting themselves to be in the class of observer-moments most common in the space of all observer moments.

Comment by SilasBarta on Quotes and Notes on Scott Aaronson’s "The Ghost in the Quantum Turing Machine" · 2013-06-17T21:13:08.428Z · LW · GW

"Causality is based on entropy increase, so it can only make sense to draw causal arrows “backwards in time,” in those rare situations where entropy is not increasing with time. [...] where physical systems are allowed to evolve reversibly, free from contact with their external environments." E.g. the normal causal arrows break down for, say, CMB photons. -- Not sure how Scott jumps from reversible evolution to backward causality.

It's a few paragraphs up, where he says:

Now, the creation of reliable memories and records is essentially always associated with an increase in entropy (some would argue by definition). And in order for us, as observers, to speak sensibly about “A causing B,” we must be able to create records of A happening and then B happening. But by the above, this will essentially never be possible unless A is closer in time than B to the Big Bang.

That is, we are only capable of remembering (by any means) things closer to the Big Bang, because memories require entropy increase; and furthermore, memories are necessary for drawing a causal arrow that orders past vs future. But if there is a system that stays isentropic, it needn't have such a ordering.

Note: this is actually very close to Drescher's resolution of Loschmidt's paradox ("why is physics time-symmetric but entropy isn't?") in Good and Real: since entropy determines what we (or any observers) regard as pastward, we will necessarily observe only those time histories of increasing entropy.

Comment by SilasBarta on Prisoner's Dilemma (with visible source code) Tournament · 2013-06-13T21:34:36.097Z · LW · GW

Just thought I'd throw this out there:

TabooBot: Return D if opponent's source code contains a D; C otherwise.

To avoid mutual defection with other bots, it must (like with real prudish societies!) indirectly reference the output D. But then other kinds of bots can avoid explicit reference to D, requiring a more advanced TabooBot to have other checks, like defecting if the opponent's source code calls a modifier on a string literal.

Comment by SilasBarta on [link] Scott Aaronson on free will · 2013-06-11T18:43:28.207Z · LW · GW

Eh, I don't think I count as a luminary, but thanks :-)

Aaronson's crediting me is mostly due to our exchanges on the blog for his paper/class about philosophy and theoretical computer science.

One of them, about Newcomb's problem where my main criticisms were

a) he's overstating the level and kind of precision you would need when measuring a human for prediction; and

b) that the interesting philosophical implications of Newcomb's problem follow from already-achievable predictor accuracies.

The other, about average-human performance on 3SAT, where I was skeptical the average person actually notices global symmetries like the pigeonhole principle. (And, to a lesser extent, whether the other in which you stack objects affects their height...)

Comment by SilasBarta on Applied art of rationality: Richard Feynman steelmanning his mother's concerns · 2013-06-10T21:15:01.488Z · LW · GW

I see that now. It didn't help that Luke_A_Somers, in defending what he did as steelmanning, kept insisting that he was "making the original argument worse".

(In any case, I don't think TB was the "steelest" man you could make here, nor the mother's real rejection.)

Comment by SilasBarta on A Viable Alternative to Typing · 2013-06-10T15:57:25.388Z · LW · GW

Sure, but I don't think EEG quality (in terms of lab vs. consumer grade) is the real bottleneck; I think it's minimizing the amount of input that must be provided at all by exploiting the regularity of the input that will be provided. The techniques available here may have been overlooked.

Comment by SilasBarta on A Viable Alternative to Typing · 2013-06-10T01:58:27.889Z · LW · GW

One character is not the same as one byte of (maximally compressed) information. The whole point of programs like Dasher (and word suggestion features in general) is to take advantage of the low entropy of text data relative to its uncompressed representation. Characteristic screenshot

Were you using a static, non-adaptive, on-screen keyboard? If so, that's why I would think connecting it to Dasher should result in a speed greater than one char per second, at least after the training period (both human training, and character-probability-distribution training).
