I've been writing blog articles on the potential of educational games, which may be of interest to some people here:

I'd be curious to hear any comments.

Have you played the Portal games? They include lots of things you mention... they introduce how to use the portal gun, for example, not by explaining stuff but giving you a simplified version first... then the full feature set... and then there are all the other things with different physical properties. I can definitely imagine some Portal Advanced game when you'll actually have to use equations to calculate trajectories.

Nevertheless... I'd really like to be persuaded otherwise, but the ability to read Very Confusing Stuff, without any working model, and make sense of it can't really be avoided after a while. We can't really build a game out of every scientific paper, due to the amount of time required to write a game vs. a page of text... (even though I'd love to play games instead of reading papers. And it sounds definitely doable with CS papers. What about a conference accepting games as submissions?)

My current anti-procrastination experiment: using trivial inconveniences for good. I have installed a very strong, permanent block on my laptop, and still allow myself to go on my favourite time wasters, but only on my tablet, which I carry with me as well.

The rationale is not to block all use and therefore be forced to mechanically learn workarounds, but to have a trivially inconvenient procrastination method always available. The interesting thing is that tablets are perfect for content consumption, so the separation works well. It also helps me to separate the contexts well, so I don't sit on the laptop "to work" but end up browsing around. Its also good for making me self aware of what I am doing at any given time, on a physical level. Finally, I tend to reject hard restrictions, but trivial inconveniences may be a good balance.

So far, the results are very encouraging, time on hacker news and news sites is way down. I have been doing this for a couple of weeks, so I am not over the two month honeymoon yet, but if anyone else wants to give this a shot and let me know how it works out, then more data for all of us!

I have a similar experience... around two years ago, both my laptop and desktop power supplies died (power surge), leaving me a pII-300... with which I had some "let's be authentic nineties" fun previously, so Win98 and Office 97. Except for the browser (lots of websites didn't even load on IE4-ish browsers), so I ended up with Firefox 3.x (the newest that ran on win98).

It actually took long times with 100% CPU to render web sites. And then further time to scroll them.

My observation is the same as yours: there is nothing better to discourage random web browsing than it being inconvinient. I could look up everything I needed to stay productive, I just didn't want to, because it was soo slow. (Having a smartphone + a non-networked computer seems to have the same effect, but with phones getting too fast nowadays, the difference seems to be diminishing...)

If people can turn off sounds and notifications, we probably don't have to worry about bothering others by chatting outside of a break.

I would think so too, but at least 1 person has requested chats that chats be at a minimum, even if he turned off the sound and notifications.

Besides that, a lobby has the advantage that you can hang out without working. Here's the failure mode I'm anticipating and trying to avoid: Let's say this becomes big, and there's plenty of people in the study room. Some will just hang out, and not specifically be working at that time. This creates an environment in which it feels "okay" to just hang out and not work when you're there.

Comment author: latanius 11 March 2013 04:03:56PM 3 points [-]

The problem with no notifications is that because you're still in a room where interesting stuff is going on, of course you'll check the chat history and/or join the people already chatting. (Unless you use up willpower not to, but the whole point is using less of that.)

Having a 25 min work + 5 min chat cycle seems to be a good thing though; start working because everyone else went silent is so much easier as going back to the "library" while everyone else is still talking in the lobby. If you're working, don't go there, that's it.

I went through an Optimization course last semester (CS, grad), so it doesn't really qualify as an "out of class experience", nevertheless reading it was quite optional, and, actually, the questions I asked myself were very similar to yours.

Especially in the light of those small remarks textbooks tend to make along the lines of "we don't have any more space here, so if you're interested, the excellent book by X and Y is a very nice read". As if they were referring to some light and entertaining book if the one you were holding weren't really enough to fill up your entire afternoon.

Instead, I spent hours on the part about Conjugate Gradients for example, coming up with different (mostly wrong) mental models, drawing various maps, and thinking about what's wrong with the way I try to study math. (I also ended up at #lesswrong, asking people how they study. Also brought home some ideas.)

So, in the second half of the semester, I upgraded my method to the proposed-by-some-people "ignore all the proofs, and generally, all of the textbook, try to complete the excercises that are likely to come up on the exam, and don't try to see everything". Which kind of worked: I understand most of the concepts, I can solve actual problems, and also, passed the exam. (As if that one counts as a proof of knowledge...)

But I'm still curious how studying textbooks is supposed to work. Like...

  • what is the goal of people when reading textbooks? being able to solve real-world problems? passing exams? solving all the excercises? getting the warm fuzzy feeling of having eaten a huge book with lots of formulas while getting that "yes I understand" feeling that may or may not be the same as really understanding stuff?
  • what is the goal of people who write textbooks? is the fact that they are hard to read an unavoidable thing, a way-too-common flaw or... are there people who read math like I read MLP fanfics? Is it possible to fix this?
  • and also, the statistics you mention. About the average WPM when reading math books...

Do you guys need an outlet for your need for the mysterious when cold hard rational thought gets too much, or something? Anyway, rationalist fiction does not have to be a rationalist fantasy or a rationalist science fiction. No magic, no vampires, no space aliens, no friendly pink immortal horses, imagine that.

Plenty of fan fiction possibilities, too. 50 shades of rationality, fighting pride and prejudice, crime and punishment: tales of a buggy mind, war and peace: System 1 vs System 2...

Good idea... especially given that the fact that the readers usually aren't an immortal vampire / pony / wizard makes it relatively complicated to emulate the protagonists.

Not to speak of the fact that much of the fictional rationalist awesomeness comes from applying existing stuff (common sense / science) in a setting where it's not expected to be applied. (See Harry's Gringotts money pump or Missy's sciencey superpowers). It's hard to extrapolate that to our world...

Counterexample: Cory Doctorow's Little Brother & Homeland. Although not really rationalist, they are full of things you can actually do in the real world (from programming and plausible deniability crypto to Burning Man).

Or Bella's notebooks. (anyone else here who actually started text files with "what do I want" and having felt at least marginally more awesome as a consequence?)

just finished reading.

It's kind of sad in a... grand way.

No one remembering anymore what exactly being "human" means. But... what do we expect? I don't see any human values that are not statisfied, it just does not "feel like home" that much. But still, orpbzvat bar bs gur yrffre fhcrevagryyvtraprf naq fgvyy univat n fcrpvny cynpr va zvaq sbe fgne gerx? It's as heart-warming as it gets, in a cold, dark and strange universe.

(If only we could do this well.)

The uploading process seemed to be destructive only for convenience's sake.

For me, it felt more realistic. I don't think anyone has actually thought of a non-destructive uploading process that is remotely plausible.

Attach lots of sensors to lots of axons, try to emulate the thing while it's running... for me, it's the on-line method that sounds more plausible compared to the "look at axons with microscopes and try to guess what they do" approach. Nevertheless, imagining a scenario with non-destructive uploads... how many times would you allow people to upload? Ending up with questions like that, I think it's the destructive one that would generate less horrifyingness...

If you are trying to do X, surround yourself with people who are also doing X. Takes much less willpower to keep doing it.

Upvote comments that you think are useful on LW in general, not just comments you found personally useful. (A note to myself as I read this thread).

Comment author: latanius 07 March 2013 08:37:05PM 5 points [-]

As for this thread: wouldn't upvoting commens that you think are useful for someone else but not for you be actually an indirect case of other-optmizing?

Using a debit card gives you most of the same benefits, but has slightly different costs. If your doing this it makes sense to research which one is best for you.

Also consider mint.com. Draws awesome graphs. (It only works for US bank accounts only though...)
