Yes. Reading HPMoR. Chapter 8 in particular.

I have been rereading HPMOR and come up with an elegant hypothesis that I found to be ever more fitting as I continued to read. However, I just realized that I have been looking only for tests that confirm my hypothesis, and not looking for things that would cause my hypothesis to be wrong. This is not the sort of realization that I often have.

5therufs
Are you aware of anything you've done lately that would make you more likely to have this sort of realization?

Once you get fairly strong, you can sometimes even win free points by apologising in front of a big group of people for something that everyone but the other disputant think is completely outweighed by the other disputant's actions.

Why would this be true? If the other disputant was so clearly in the wrong, wouldn't it be obvious that that's what you're trying to do, thus voiding the effect?

2KnaveOfAllTrades
Sure, it wouldn't always be effective. But things that--when described linguistically to you--sound obvious can be subtle enough when they actually happen to others that they work anyway. Actually believing that you have acted imperfectly and can do better next time and conveying this in apology form makes it less obvious. And in fact, if you are trained to apologise for little things in the face of big things even without an audience, then your outward conduct may even be mostly indistinguishable between the two cases anyway.

Interesting. Does this.... urgency ever turn out to be useful? I'm assuming that at the worst it's not distracting enough to justify taking the time to prevent it.

(In case I was not clear, I was talking about a more general thingy than being sat upon. Pretty much all of 6.3 for example.)

2arundelo
I'd say it ranges from enjoyable through distracting-but-pleasant to just distracting, but it's never bad enough to noticeably affect my ability to get stuff done. Maybe it sometimes was in my teens and twenties, but I haven't been able to remember a clear example. Arguably one example would be my wrestling anecdote. That feeling was sudden enough (my friend "attacked" me without warning) and intense enough to make me not able to fight back very well. Long story, but this meant that the playfight didn't last as long as I would have liked it to.

So I've been reading Worm ( parahumans.wordpress.com ), and there's this tiny thing that's been growing ever-more annoying, and I can't hold off asking about it any longer.

I keep seeing passages like this: "Realizing the position he had me in, feeling the pressure of his thighs against my hips, his weight resting partially on my lower body, I must’ve blown a synapse. My thought process ground to a halt. It didn’t help that the first place my mind went was interpreting his ‘start’ as being this position leading to something else."

Do people actually think like this? Seems like it would be really inconvenient.

0CAE_Jones
Yes. Not even being attracted to anyone, physical contact (especially the close kind in grappling) tends to have me consciously trying not to panic over those sorts of implications. It might be a cultural thing? Possibly mixed with personality type/experience? (Yes, it is annoying.)
2drethelin
I've had moments like that. It's much more of a thing I think when you're extremely lonely and inexperienced. But I still get emotional thrills when sitting in very close contact to someone I find attractive regardless of the fact that I have plenty of physical fun these days.
6Shmi
I've just finished Worm! At the pace of 10^5 words/week it left me little time for other activities. I hope someone makes a movie out of this web novel, it's so visual. Anyway, the passage you quoted seems like a perfectly good description of one's physical contact with her crush. Especially if it's the first crush of a not-quite 16 year-old girl.
9arundelo
I pretty rarely wrestle with people (or otherwise have such close physical contact), so if someone I have a crush on is literally sitting on top of me pinning me on my back, I have trouble staying calm. (I'm thinking of a particular time this happened to me. I felt about like Taylor does in your Worm quote.)

I'm having trouble reading your footnote. What am I supposed to make of the numbers 12 and 13?

They were the original author's footnotes. Deleted 'em.

I do have a bit of a problem saying no, largely, I think because I 'respect' authority too much. For example, right now I am the only person working on a series of projects, the sort of which an entire team normally handles. But now everyone's depending on me, so it's too late to back out.

However, I say no a lot more than I used to, and it is amazing.

There is little to tell. Basic Training has more to do with getting used to being miserable than actually pushing yourself. The actual job training is somewhat more challenging, but only because there is very little room for error. You aren't allowed to bring stuff home to study either, so there's little extra you could do even if you wanted to.

I did force myself up and down 800-some steps (as in a staircase sort of thing) while wearing about 90 lbs (I weigh 140) of gear, but that was completely voluntary. It was excruciating, but I recognized that quitti... (read more)

If I understand it correctly, much of the power in Beeminder comes from the threat of losing money when you fail. How many times did you fail at writing before giving up? I have not used BM in a while, but I did successfully use it for writing.

(Number of consecutive push-ups doesn't seem like a good thing to Beemind. If your body doesn't have 50 push-ups in it, wanting it really bad isn't going to help much. Tracking number of push-ups done in a given amount of time would probably work better, which would naturally increase consecutive pushups.)

2dreeves
I very much agree with the parenthetical about pushups. I beemind 30 pushups per day -- http://beeminder.com/d/push -- with the idea that I'll gradually ramp that up as my max reps increases. Except I'm failing to ever do that and have been at 30/day forever. If I cared more I'd ramp it up though. Right now I'm just happy to be forced to maintain some semblance of baseline upper-body strength. The general point: beemind inputs, not outputs. Ie, things you have total control over. PS: The Beeminder android app has a pushup counter built in, where you put your phone on the floor and touch your nose to it on each pushup and it tallies them for you.

I don't follow. What does "All the world is a stage" have to do with anything? What do you mean by 'competition of all effective varieties' and why should anyone avoid it? What is the goal, and how is testing a rationality skill losing sight of it?

Interesting, would you be willing to say more about your experience? That definitely sounds to me like something that would be an interesting and difficult challenge.
jetm100

I've considered joining the army for a similar reason of pushing myself to become stronger.

For me, the military did not push me nearly as hard as I expected. Pushed myself harder while preparing for it than I was pushed in Basic Training. Advise not doing this, or at least joining Marine Corps instead for proper pushing. There are also things (i.e. Tough Mudder) that can similarly physically push you without requiring you to sign a contract.

0katydee
What's your MOS (or equivalent)?

This is a good point; there are almost certainly ways to get the important parts of the military experience without paying the costs.

This is, of course, more ideal. Sadly, I get most of my books from unrenewable inter-library loans and therefore require an unfortunate focus on speed.

And now that I type this, I realize that nothing stops me from requesting a different edition of it a week or two before my current one is due......

I am beginning to track my motivation so I can have something of an idea of how often I ought to 'refuel' as well as what sorts of things work for 'refueling.'

I began to schedule a chunk of time to make a to-do list for the next day in my daily to-do lists. They work great when I actually make them, but I remember to make them less than half the time.

I did not see this up there. I cannot think of a dense was of saying this at the moment, so I'll go ahead and ramble and hope someone finds it useful.

I am currently slogging through Causality by Pearl. It's probably a little above my level, but I'm getting most of it. However, just a little bit into the first chapter, he throws in stuff about covariance and regression coefficients that go way over my head. I almost gave up. Fortunately, I recognized them as terms from statistics. I inferred from his rapid coverage of it that it was included as an 'ooh, shi... (read more)

M, my usual reflex in situations like that is to pause, look up the terms in question, as well as associated wikipedia pages, and see if I'm missing any basic knowledge; and once I'm more comfortable with those, go back to the more advanced book/article.

When you said to suppose that "everything we want is [impossible]", did you mean that literally? Because normally if what you want is impossible, you should start wanting a different thing (or do that super-saiyan effort thing if it's that kind of impossible), but if everything is impossible, you couldn't do that either. If there is no possible action that produces a favorable outcome, I can think of no reason to act at all.

I didn't mean it literally. I meant, everything on which we base our long-term plans. For example: You go to school, save up money, try to get a good job, try to advance in your career... on the belief that you will find the results rewarding. However, this is pretty easily dismantled if you're not a life-extensionist and/or cryonicist (and don't believe in an afterlife). All it takes is for you to have the realization that 1) If your memory of an experience is erased thoroughly enough (and you don't have access to anything external that will have been altered by the experience) then the experience might as well have not happened. Or insofar that it altered you through some other way than your memories, is interchangeable with any other experience that would have altered you in the same way. 2) In the absence of an afterlife, if you die all your memories get permanently deleted shortly after, and you have no further access to anything influenced by your past experiences including yourself. Therefore, death robs you of your past, present, and future making it as if you had never lived. Obviously other people will remember you for a while, but you will have no awareness of that because you will simply not exist. Therefore, no matter what you do, it will get cancelled out completely. The way around it is to make a superhuman effort at doing the not-literally-prohibited-by-physics-as-far-as-we-know kind of impossible by working to make cryonics, anti-aging, uploading, or AI (which presumably will then do one of the preceding three for you) possible. But perhaps at an even deeper level our idea of what it is these courses of action are attempting to preserve is itself self-contradictory. Does that necessarily discredit these courses of action?

Are you using any tools to keep yourself cut off, or do you merely choose not to visit those sites?

0LM7805
In the past I've manually edited my hosts file to point time-wasting sites to 127.0.0.1, which is a small obstacle at most -- I can easily edit it back -- but is enough of a speedbump to remind me "oh, right, I'm trying to avoid that right now." This time I haven't needed to; I managed to become so frustrated with the fact that my queue was saturated with short-term rewards that weren't netting me anything in the long run that choosing not to visit the sites doesn't seem to require much willpower. This leads me to wonder whether I could eliminate other influences I want to avoid by making myself sufficiently frustrated with them, but that seems like it would be an unpleasant skill to pick up.

"Why? Do you get extra points for doing things the hard way? As opposed to: choosing the right tool for the job."

I don't know what potential employers are looking for (and now I realize that I haven't even tried to find out), but I would expect them to be more impressed with a thing if I were to do it in a more 'difficult' language than if I did the same thing in a language that needed only two lines of code for the job. My focus is on signaling my skill, rather than completing the program itself.

Then again, I'm thinking it would be even more impressive to learn Python's deepest secrets and exploit them to the max.

1Viliam_Bur
Data point, possibly completely irrelevant: When I am looking for a Java programmer job in Slovakia, pretty much the only thing employers care about is how many years did I program in Java and which frameworks did I use. -- Which in my opinion is completely stupid, because I consider the ability to write and understand algorithms much more important; and a new framework is just something you can learn in a month or two, if your algorithmic skills are solid. I guess the problem is with the fact that the employers who make the decision are not coders themselves, so speaking about algorithms is simply too abstract for them, but asking questions like "how many years?" and "are you familiar with XYZ, yes or no?" gives them a false sense of understanding. More generally, you are a perfect employee if you did something extremely similar to what your new employers wants to do, for the last ten years. So another good question is: what kind of projects are the employers in your target group typically doing? (For Java programmer in Slovakia it is: a database application with a web interface, most likely in finance.) Then do a simple demo, using the "right" framework; which is the one most frequently mentioned in online job searches. Note: In my case, programming games would be almost completely irrelevant to a real job experience. Although there would be some transferrable skills, such as commenting the code, maintaining a large program, understanding threads, etc. But I would completely miss communicating with the database and creating HTML pages, and knowing hundred specific details (and dozen bugs) of the relevant frameworks, which make most of my daily work. But the problem is that there will be dozen frameworks doing pretty much the same thing, and new ones are still invented, and the old ones are redesigned. You just won't have time to keep up with all of them. So the framework-based knowledge is prone to obsolescence, which drives some programmers into despair. You n

Huh. After reading that, I'm thinking it might be more impressive to switch to something less ridiculously simple than Python.

More importantly though, you made a great point about the halo effect. I had completely forgotten to take that into account. On further reflection, I realized that I consistently forget to account for the halo effect, and that it may be in part because I wish to believe it does not exist. This could use some work.

4Viliam_Bur
Why? Do you get extra points for doing things the hard way? As opposed to: choosing the right tool for the job. (I am not familiar enough with Python, so this is not a comment endorsing Python, just a reaction to the "less ridiculously simple" part. If two programs do the same thing, what's wrong with the simpler one?) Yeah. We programmers are proud of our ability to write complex code, so we wish complex code was the most admired thing about computer programs. Unfortunately, most people are impressed by nice screenshots. (At the first moment. When they use the program for some time, they start caring also about things like working properly, not crashing, etc. But to get them there, you need a nice screenshot first.)

My current plan is to focus on simplistic games such as Pong and Caterpillar, as well as programs designed to play said games

2Viliam_Bur
I think this is a very good plan. It is good to make simple games (or merely demos of the concept) first, because the distance between no game and a simple game is probably greater than between a simple game and a complex game. So if you make a simple game, you solve the problems on simple instances, and then you are ready to deal with them in more complex situations, because the core ideas are now clear. For example, even very simple games usually contain a lot of the following: loading bitmaps from files, displaying bitmaps, loading music from files, playing music, reading user input, calculating coordinates, calculating movement, calculating collisions, timing and animations, keeping values in variables, switching between introductory screen and game screen and victory/defeat screen. -- Which is a lot of things, especially if you are doing it for the first time. And each of those things can become a separate problem, with subproblems, such as: "what to display on the screen while the bitmaps are loading, and what to do if the loading fails". Also, the language and libraries may create additional problems, for example to make animations in Java you have to understand the thread model and synchonization, otherwise mysterious bugs can happen. And I am still speaking about a Pong-like game. Then a complex game contains more of the previous things, plus: reading configuration files, saving and loading a game, AI opponents, perhaps an installation program. (And nicer graphics and music, but that is outside of the programming scope.) So doing the simple game properly -- not just on the "it works (most of the time)" level, but having a clear design and understanding how and why the parts cooperate -- is a very good start for making a complex game. (Here is a trick you may find useful: After making the algorithm, you can hugely improve the impression of the game by adding nice graphics, even when some parts of graphics are completely irrelevant to the algorithm. For e

I am currently pursuing a BS in Comp Sci at an obscure online university. I decided to supplement this with classes from Udacity.

Another idea is to use different browsers for different tasks. For example, Firefox for school, IE for goofing off, and Chrome for extra-curricular projects.

Anyway, time to remove all the books I will likely not want to look at in the near future to make room for useful things like my calendar and vitamins.

What I want to do is to figure out what I want to do. My basic (and vague) goal is to do the most amount of good with my future career. If I make that decision with my current tools, I will likely overlook something.

If I'm reading this correctly, if A is true and the evidence available to you for A is false, you wish to believe that A is false? Or am I missing something?

-1Shmi
Note that this statement only makes sense if you already subscribe to physical realism, as it presumes the territory separate from any maps. If you don't make this assumption, this statement means that "at some point I will acquire evidence confirming the model based on A with very high confidence". The currently available evidence may be against A, however. It happens quite often in physics, though not it trivial ways. For example, light was believed to be composed of particles, until the Poisson's spot was discovered. There was plenty of experimental evidence for it, too. Afterwards, light was believed to be waves, and there was overwhelming evidence for this, as well. Then the UV catastrophe was deduced and the photoelectric effect was discovered, demonstrating that the question "is light a wave or a particle" has a different answer, depending on the manner of asking. The story is far from over at present. I wish to believe that I will update my beliefs based on available evidence (a bit meta here).
