Trans-human thought experiment:

  • Scenario 1: A human brain is converted to a virtual brain through a destructive process (as described in many science-fiction stories). In what sense is this virtual intelligence the same "person" as the original, organic person?
  • Scenario 2: A human brain is converted to a virtual brain through a non-destructive process. The original, organic person lives on as before. In what sense is this virtual intelligence the same "person" as the original, organic person – is this the same as the answer in scenario 1?

Why this seems to matter: If a virtual version of me is not really me in the sense of being a continuation of my experience, then what does it matter to me if that virtual brain exists, as opposed to some other virtual brain? Is there actually any advantage to working out how to convert people en masse to virtual intelligences?

(I am aware that the questions of identity and "being a continuation of my experience" are vague but I anticipate that replies here will help me get clearer. )

Does anyone have any good ideas about how to be productive while commuting? I'll be starting a program soon where I'll be spending about 2 hours a day commuting, and don't want these hours to go to waste. Note: I have interests similar to a typical LessWrong reader, and am particularly interested in startups.

My brainstorming:

  • Audio books and podcasts. This sounds like the most promising thing. However, the things I want to learn about are the hard sciences and those require pictures and diagrams to explain (you can't learn biology or math with an audiobook). I'm also in the process of learning web development and design, but these things also seem too visual to work as an audiobook.

  • Economics audiobooks might work, idk. I could also listen to books about startups/business, but I'm at the point where I know enough about these things that diminishing returns have kicked in.

  • I've read a good amount about psychology already, and feel like diminishing returns have kicked in. Although psychology seems like it'd work well with an audiobook.

  • Perhaps sci-fi audiobooks would be good? Would I learn from these or would it just be entertaining? Any suggestions (I read 1984, Enders Game and Brave New World. I liked them, but didn't learn too much from them.

  • I read HPMOR and loved it. Anything similar to that?

  • Other than audiobooks, I could spend the time brainstorming. Startup ideas, thought experiments, stuff like that.

Given the limitations (that you describe in other replies) I think you've got a good list.

Regarding podcasts, this could be a great time to experiment with new ones & decide which you want to listen to longer term.

Perhaps there are some short activities of value to you, such as Anki (assuming you have a smartphone), mentally reviewing your memory palace, or mindfulness exercises. Mindfulness exercises on public transport may seem a little odd, but the distractions may make it more effective as exercise - just be patient with yourself.

I'm currently a post-doc doing language technology/NLP type stuff. I'm considering quitting soon to work full time on a start-up. I'm working on three things at the moment.

  • The start-up is a language learning web app: http://www.cloze.it . What sets it apart from other language-learning software is my knowledge of linguistics, proficiency with text processing, and willingness to code detailed language-specific features. Most tools want to be as language neutral as possible, which limits their scope a lot. So they tend to all have the same set of features, centred around learning basic vocab.

  • Something that's always bugged me about being an academic is, we're terrible at communicating to people outside our field. This means that whenever I see a post using an NLP tool, they're using a crap tool. So I wrote a blog post explaining a simple POS tagger that was better than the stuff in e.g. nltk (nltk is crap): http://honnibal.wordpress.com/2013/09/11/a-good-part-of-speechpos-tagger-in-about-200-lines-of-python/ The POS tagger post has gotten over 15k views (mostly from reddit), so I'm writing a follow up about a concise parser implementation. The parser is 500 lines, including the tagger, and faster and more accurate than the Stanford parser (the Stanford parser is also crap).

  • I'm doing minor revisions for a journal article on parsing conversational speech transcripts, and detecting disfluent words. The system gets good results when run on text transcripts. The goal is to allow speech recognition systems to produce better transcripts, with punctuation added, and stutters etc removed. I'm also working on a follow up paper to that one, with further experiments.

Overall the research is going well, and I find it very engaging. But I'm at the point where I have to start writing grant applications, and selling software seems like a much better expected-value bet.

TIL: NLP can mean Natural Language Processing, as well as Neuro Linguistic Programming. I was confused for a while there.

I've been practicing stenographic typing daily for the last couple of weeks, but still am not at a point where I have a serious write-up or a better typing speed ready.

I'm working on this mostly to prove to myself that I can see long-term projects through. Sure, the promise of doubling my typing speed on English language input is promising, but it's really too far off to be that tempting. So it's mostly to show that I can keep working on a project if I keep my mind to it. That, and there are some people on this site who are rather interested in how it turns out - how much work it was, how difficult, how long it takes to get good enough at it, etc. I almost forgot the big one: if typing in steno makes a difference in the ease of writing.

When I get significantly faster than my QWERTY typing speed - 140 WPM over my original 90 - I'm doing a write-up on the experience.

Here's links with the software and learning tools I'm using: http://plover.stenoknight.com/ http://qwertysteno.com/Home/

Keyboard: Microsoft Sidewinder X4. You need a keyboard that can correctly send combinations of key presses to the system - it's called N-key rollover - and this is a $50 option that satisfies my needs.

EDIT: I realized that my write up was missing a lot of the actual strategies I used to practice. There are three skills I am working on. Steno theory, keyboard use, and brief memorization.

Steno theory is how you figure out the chords needed for an unfamiliar word. So for the word "needed", I'd type that as "TPHAOED/-D". TPH is the letter N, AOE is the long E vowel sound, and D is the final D. Then the -ed final sound is an unvoiced vowel and a D, so it's a final D. I practice this by typing things using steno - I invariably find words that I don't have memorized chords for, and then I figure it out or fail to and look it up.

The keyboard use is mostly a byproduct of use, with a little bit of http://stenoknight.com/stengrid.png for the multi-key consonants. I got started with the key drills either in qwertysteno or the typing drills at https://sites.google.com/site/ploverdoc/lesson-1-fingers-and-keys

For brief memorization, I'm using the top 100 words drill at http://qwertysteno.com/Practice/Words1.php , and limiting the range to a manageable few common words to spam out quickly (I started with ten). Once there's little thinking involved, it's time to add more words. This is really the nuts and bolts about how to type quickly with steno - the most common words are most of what you're going to be using, so it's where you get the most bang for your drilling buck. Well, if you get hung up on unfamiliar words you're better off working on that - occasionally needing twenty seconds to get a word out is a lot of time even if it's one word in sixty. But the words you want to get faster on are more common, so it's a good tool to get the most common words practiced first and most.

How is your stenographic typing progressing? What has the return on effort been for you, so far?

Question for anyone that's taking the course: is it worthwhile for the average LW'er? I assume most of us have an above-average familiarity with these topics.

I've done the first 6 weeks now, and finding it very easy - but I'm definitely learning something each week.

If you already know about the roles of different parts of the brain (e.g. orbitofrontal cortex, amygdala, DLPFC) and their interactions, then it might not be word your time. For me it's worth the time. Playing the videos at high speed helps.

I love it... but I need to make sure I get up & move during the breaks rather than sitting and chatting.

I just used it for the first time. Very valuable, but the Android Tinychat app seems unreliable.

I have upvoted your post in the hope that it will contribute to your positive feelings about having written it, so that you will continue to write intelligent and thoughtful posts in future.

Do we need a definition of "deserve"? Perhaps it does not correspond to anything in reality. I would certainly argue that it doesn't correspond to anything in politics.

For instance, should we have a council that doles out things people deserve? It just seems silly.

Politics is ideally a giant cost/benefit satisficing operation. Practically, it is an agglomeration of power plays. I don't see where "deserve" fits in.

Comment author: CWG 05 March 2014 08:27:07AM 1 point [-]

A "council that doles out things people deserve" sounds like Parecon: Life After Capitalism by Michael Albert.

(Personally, it fills me with horror, but there are people who think it's a good idea.)

"Mind reading" - how is this done?

I just want to burn him at a stake and watch his witch's heart bubble. It’s extraordinary. Great trick. - Stephen Fry

Derren Brown does many amazing tricks - I want to focus here on his "mind reading". This is way beyond any cold reading I've seen, but he insists that he uses no actors or stooges. He's also a skeptic, very clear about not being psychic. He does reveal some of his tricks, but maintains a lot of mystery.

Reading David Frost's mind - unusually, he struggles and gets the first one wrong, and seems to reveal tiny glimpses of his technique. Then at the end he gives more hints about his technique than usual. 

Pet name - getting someone on the street to read another person's mind. In the full version (from the DVD of Trick of the Mind, series one) the segment starts with Derren telling the guy (the pet owner) that sorry, it won't work on you, then later changing his mind and bringing him in.

Creepy clown - the detail here is extraordinary. 

Watch the videos then scroll down, if you want to watch it without being influenced by me... I have a few thoughts, but they don't go very far in explaining it...

       - - - - - - 

Whatever he's doing, he's extraordinarily good at it. Some speculations:

  • Derren Brown uses suggestion and "subliminal" messages very heavily in his tricks. Often he will have written down the person's choice long before they've chosen, and subtly gets them thinking about what he wants. In the examples above he doesn't have much opportunity to direct the thought, I think... except that in the case of David Frost choosing a place, Frost is looking in the direction of the city scape behind Derren, which presumably influences his choice. 
  • Micromuscle reading: When he or a participant tries to read a thought, there's often something about picking up the sound of a letter. Perhaps he reads involuntary micromuscle movements related to the mouth and throat that happen while saying something loudly in one's head, but suppressing it. (I would have guessed that was impossible... it still seems unlikely, but much more likely than "he's psychic".)
  • He narrows down the field of possibilities, often through suggestion, or sometimes (as with David Frost) asking them for something more specific. 
  • He usually selects the participant, making sure he's got someone suitable. Perhaps all TV show hosts are suitable. (Except in his stage shows, where he throws a teddy bear into the audience, and asks the audience to throw it again. Perhaps if you've bought an expensive ticket to his show, you're invested in it and ready to go along with him, and that's enough for those particular tricks.) He says that a few things increase suggestibility, including the presence of a camera.
  • He's extremely observant and good at making connections - in one trick, he tells a man a lot about himself, by holding his hands through holes in a panel, but not able to see the man. E.g. by the roughness of the man's hands, he guesses what sport he's interested in. He pulls his hands back, smells them deeply, then declares that he has terriers (correct - he attributes that to having learnt to tell the difference between breeds of dogs by their smell), probably 3 of them (correct - no idea how). 
  • Any of these things might be misdirection. 
  • He may be lying, and actually using actors & stooges in some of his tricks. But that doesn't explain everything very well (e.g. I doubt that David Frost, Jamie Oliver or other celebs were paid to go along with him, but again, it's more believable that they're all lying than that he's psychic.)
I think he's using a lot of different methods at once, with great skill... but I'm sure my speculations are a long way short of explaining what he does. I'd love to hear any further insights on his mind-reading.

Since no one else seems to have said this yet: I like getting responses, and even huge delays are not an issue! :)

I occasionally reply to year old posts, and occasionally get replies to year old comments/posts of mine. I enjoy both of these situations - the latter tends to prompt me to revisit a topic, and I'll often have new insights or perspective since I've only been at this 'rationality' thing for a couple years.

5-day-old responses are rarely even noticed by me - I'm used to 1-2 weeks for a reply to m personal email! Not everyone checks the internet daily, and people often vanish for weekends, vacations, or just general being-busy or low-on-spoons.

Edit: I'd also suggest that a community norm of "It's okay to reply, even 2 years later" would be cool - if the person being-replied-to doesn't want to revisit the topic, they can just ignore the reply, after all.

Me too. I get frustrated by forums where old threads are routinely closed, or where participants are rebuked for bumping an old thread.
