I used diigo for annotation before clearly had highlighting. Now, just as you, use diigo for link storage and Evernote for content storage. Diigo annotation has still the advantage that it excerpts the text you highlight. With Clearly if I want to have the highlighted parts I have to find and manually select them again... Also tagging from clearly requires 5 or so clicks which is ridiculous... But I hope it will get fixed.

I plan to use pocket once I get a tablet... it is pretty and convenient, but the most likely to get cut out of the workflow.

Thanks for the evernote import function - I'll look into it, maybe it could make the Evenote - org-mode integration tighter. Even then, having 3 separate systems is not quite optimal...

Would love to read a gwern-essay on your archiving system. I use evernote, org-mode, diigo and pocket and just can't get them streamlined into a nice workflow. If evernote adopted diigo-like highlighting and let me seamlessly edit with Emacs/org-mode that would be perfect... but alas until then I'm stuck with this mess of a kludge. Teach us master, please!

Fair enough, though it is really hard to say what's supposed to go to the open thread (which really should be sticky so that it is bit more accesible). Massimo Pigliucci is a fairly known figure in the rationalist/skeptic/naturalist community. That doesn't mean that I endorse his views (by far not - and not specifically for this article).

As a counter-example a seemingly random comment on an somehwat related blog got a full blown reply from Luke (meaning his reply to Mark Linsenmayer), though part of your critique is that I didn't comment on the article (unlike Luke), which is fair enough - the reason being that I'm not familiar enough with Eliezer's original post.

I agree and tried to be careful saying "some people" (which is not exactly good practice, I know). As I noted below Motl is a fascinating specimen. I certainly don't consider him to be a an authority on who is a crackpot or not, nor do I agree with many of his opinions or methods.

Gosh, thanks, fixed it... I know I'm not the first to screw this up, but still...

Yes, Motl has to be handled with lot's of care, though usually as far as physics goes I find him alright (unlike say climate change and a bunch of other stuff). His tone can be off-putting, but I see him still as a useful contrarian in some areas and generally an interesting case study of an extremely bright person with some strange opinions and a very... interesting personality (to put it mildly).

It is strange that "Forty Years of String Theory: Reflecting on the Foundations" doesn't have any of the bigger names from string theory (particularly, no Ed Witten?), but has pretty much the full list of controversial (some people would say outright currently crackpotish[1]) names like 't Hooft, Verlinde, Smolin and lately also Susskind. I am not picking sides, but this raises all sorts of red flags about it. I bet Motl will be all over this.

I'll have a look at Susskind's paper, particularly if he is railing against reductionism.

[1] 't Hooft's and Susskind's contributions to modern theoretical physics can't be understated, but their general reputation suffered in recent years.

Just for fun a recent paper:

Constraints on the Universe as a Numerical Simulation

Silas R. Beane, Zohreh Davoudi, Martin J. Savage (Submitted on 4 Oct 2012) Observable consequences of the hypothesis that the observed universe is a numerical simulation performed on a cubic space-time lattice or grid are explored. The simulation scenario is first motivated by extrapolating current trends in computational resource requirements for lattice QCD into the future. Using the historical development of lattice gauge theory technology as a guide, we assume that our universe is an early numerical simulation with unimproved Wilson fermion discretization and investigate potentially-observable consequences. Among the observables that are considered are the muon g-2 and the current differences between determinations of alpha, but the most stringent bound on the inverse lattice spacing of the universe, b^(-1) >~ 10^(11) GeV, is derived from the high-energy cut off of the cosmic ray spectrum. The numerical simulation scenario could reveal itself in the distributions of the highest energy cosmic rays exhibiting a degree of rotational symmetry breaking that reflects the structure of the underlying lattice.

Have you encountered specific instances where asking such a question in the open thread didn't provoke a desired response?

No, I haven't. Actually, I very rarely check the open thread (though trying to rectify this). I think it might help to have this (and maybe a couple other recurring threads) to be sticky.

If there was enough personal questions it might be worth to have a thread for them. If one of the aims of LW is to improve life via rationality, this is well aligned and likely a useful thing. How to properly ask such a questions would have to be worked out too...

As said - the deck is not intended to serve for memorization of the definitions as they appear in the wiki, but to get acquainted with the concepts.

This is how I approach also other LessWrong decks (those listed in the wiki for example). It is a bit different from the type of information for which Anki is actually best applicable such as learning vocabulary, capital cities etc.

The default rate in Anki is ~20 new cards - creating this amount of proper cards daily is a huge time barrier (at least for me... even at 10/day).

That been said it woud be great to have a proper Anki deck with the LessWrong glossary.

This is interesting. Today was my first day of pomodoro usage (I use Rescue Time since a while). Afternoon I just decided to switch it off because I found it to kill my flow... That been said the reason why I started with pomodoro today was because I was procrastinating and used the time to try several pomodoro timers. My problem is getting started and hoped that setting myself to just do 1 pomodoro would make it easier to get going (which it didn't help...).

But once I am going I can work easily more than an hour without distractions (this I know from Rescue Time) and maybe pomodoro won't be a good solution for me. Stil it was just a first day, will try again, maybe also experiment with longer work units...

Daniel Kahneman in Thinking, Fast and Slow:

I had stumbled onto a significant fact of the human condition: the feedback to which life exposes us is perverse. Because we tend to be nice to other people when they please us and nasty when they do not, we are statistically punished for being nice and rewarded for being nasty.

There reason for that lies in regression to the mean when training (example of flight instructors in the israel airforce):

I pointed out to the instructors that what they saw on the board coincided with what we had heard about the performance of aerobatic maneuvers on successive attempts: poor performance was typically followed by improvement and good performance by deterioration, without any help from either praise or punishment.

Since positive reinforcement is so counterintuitive: don't forget to reward yourself for rewarding somebody for good behaviour! :)

I've heard two discussions with him (with Paul Krugman and on Singularity on 1 on 1) and he came across as well articulated and with a decent understanding of the issues. He talked about how he changed his mind and grew more skeptical of singularity, but I don't know what causes this hostile reaction... :) Oh well...

Comment by mapnoterritory on Wanted: "The AIs will need humans" arguments · 2012-06-14T12:36:49.796Z · score: 0 (0 votes) · LW · GW

Note that this claim is distinct from the claim that (due to general economic theory) it's more beneficial for the AIs to trade with us than to destroy us. We already have enough citations for that argument, what we're looking for are arguments saying that destroying humans would mean losing something essentially irreplaceable.

I don't think there are particularly good arguments in this department (those two quoted one are certainly not correct). Except the trade argument it might happen that it would be uneconomic for AGI to harvest atoms from our bodies.

As for "essentially irreplaceable" - in a very particular sense the exact arrangement of particles each second of every human being is "unique" and "essentially irreplaceable" (bar now quantum mechanics). An extreme "archivist/rare art collector/Jain monk" AI might want to keep therefore these collections (or some of their snapshots), but I don't see this to be too compelling. I am sure we could win a lot of sympathy if AGI could be shown to automatically entail some sort of ultimate compassion, but I think it is more likely we have to make it so (hence the FAI effort).

If I want to be around to see the last moments of Sun, I will feel a sting of guilt that the Universe is slightly less efficient because it is running me, rather than using those resources for some better, deeper experiencing, more seeing observer.

Alright, thank you. As far as the last paragraph goes, I took it of course more on the "metaphorical" level. I agree their evolutionary agent might be too restricted to be fully interesting (though it is valuable if their inferiority is demonstrated analytically not only from simulations).

Since it seems you have lot's of experience with IPD, what do you think about the case B)? The paper makes the claim specifically for the ZD strategies, but do you think this "superrationally" result could generalize to any strategy which has also a theory of mind? On the other hand Hofstadter's idea was in the context of one-shot PD, so this might be not apply in general at all... I need to learn more about this subject...
