  on: Work on Robin Han­son compilation

  EDIT

  Thanks for the replies and sorry for the inaccuracies. I initially reported 4,331 blog posts and 890k words; the real results are that Robin wrote 3,302 blog posts (thanks DominikPeters for pointing this out, and for finding these better urls) and 1.5M words.

  (4,331 blog posts corresponds to all authors on overcomingbias. 890k words doesn’t represent anything, because the posts were truncated when accessed from the monthly archive urls.)

  # Get the real number of words from Robin
  $ n_current_pages=331
  $ echo https://​​www.overcomingbias.com/​​author/​​robin-hanson > /​tmp/​page_urls
  $ for i in $(seq 2 $n_current_pages); do echo https://​​www.overcomingbias.com/​​author/​​robin-hanson/​​page/​​$i >> /​tmp/​page_urls; done
  $ getwords() { curl $1 | pup ‘#content’ | html2text—ignore-links | wc -w; }
  $ export -f getwords
  $  parallel getwords < /​tmp/​page_urls > /​tmp/​words_by_page
  $ awk ‘{sum += $1} END {print sum}’ /​tmp/​words_by_page

  in reply to: Fabien Roger’s comment on: By De­fault, GPTs Think In Plain Sight

  Another mitigation strategy against the “LLM learns steganography from other LLM’s output” problem is to add some noise to the training data (performing a number of transformations that preserve meaning) prior to training, to break the embedded steganography schemes. I feel like this should be relatively easy and effective?

  Note that the loss would obviously be worse on the outputs of the previous LLM.

  Which makes me think that comparing losses could be a way to detect that some text contains steganography, even if we can’t pinpoint how exactly (but our transformations break it).

  EDIT: in case of disagreement, I can try being more specific about my claim that this should be relatively easy and effective, using concrete examples. Basically I believe that after scrambling, there can only remain a small number of bits of steganographic information per token, even for a steganographic encoding that originally used the null space of natural language optimally.

  on: Pre­dic­tions for fu­ture dis­po­si­tions to­ward Twitter

  “Twitter” has a high variance. For some people (probably the vast majority of them), the comparison to smoking is certainly relevant; for a few others, Twitter is very beneficial. Here are a few variables that I think have a huge impact on the overall value a user derives from Twitter:

  1. Who are you? What’s your mental state like?

  2. What do you want from Twitter (read thoughtful discussions? participate in them? be aware of relevant news and opportunities? meet like-minded people? influence people? increase your follower count /​ gain status? escape from boredom? etc)?

  3. Who do you follow, unfollow, mute, partially mute?

  4. When and how often do you engage with Twitter?

  5. How frequently are you reading vs writing publicly vs writing DMs?

  6. When you’re only reading, how fast are you scrolling and how much are you thinking?

  7. What client do you use?

  8. Do you read tweets from your home timeline, from lists or from specific users’ profiles?

  9. Are you continually trying to improve the quality of your experience?

  I’m probably missing many others.

  on: Vim

  In my opinion, the 4 killer features of vim beyond moving around and basic editing are:

  • macros

  • the s command used with regular expressions

  • the g command (see e.g. Power of g)

  • the ability to run text through any Unix utility (Vim and the shell)

  If you know your Unix utilities (I often use awk inside of vim; it’s also great outside of it), your regular expressions, and these features, you can sculpt any text as you wish. What I mean is that you can take the output of pretty much anything, in a messed up format, and transform it into the content and format you want. This is supposed to be inspiring but I’m not sure how good a job I’m doing.

  Also, if anyone’s interested, here are my current vim Anki cards. I use Anki for keyboard shortcuts which are supposed to be muscle memory, AMA

  If you are very good at cyber and extremely smart, you can hide vulnerabilities in 10k-lines programs in a way that less smart specialists will have trouble discovering even after days of examination—code generation/​analysis is not really defense favored

  I think the first part of the sentence is true, but “not defense favored” isn’t a clear conclusion to me. I think that backdoors work well in closed-source code, but are really hard in open-source widely used code − just look at the amount of effort that went into the recent xz /​ liblzma backdoor, and the fact that we don’t know of any other backdoor in widely used OSS.

  The main effect of a market being underground is not making transactions harder (people find ways to exchange money for vulnerabilities by building trust), but making it much harder to figure out what the market price is and reducing the effectiveness of the overall market

  Note this doesn’t apply to all types of underground markets: the ones that regularly get shut down (like darknet drug markets) do have a big issue with trust.

  Being the target of an autocratic government is an awful experience, and you have to be extremely careful if you put anything they dislike on a computer. And because of the zero-day market, you can’t assume your government will suck at hacking you just because it’s a small country

  This is correct. As a matter of personal policy, I assume that everything I write down somewhere will get leaked at some point (with a few exceptions, like − hopefully − disappearing signal messages).

  in reply to: kerspoon’s comment on: How You Can Gain Self Con­trol Without “Self-Con­trol”

  Interesting… Can you tell more about how your self-control training looked like? Like when in the day, how long, how hard, what tasks, etc? Was the most productive period in your life during or after this training? Why did you stop?

  To carry on with the strength training comparison, we’re usually trying to achieve a maximum deployed strength over our lifetime. Perhaps we’re already deploying as much strength as we can every day for useful tasks, so that adding strength training on pointless tasks would remove strength from the other tasks?

  on: Moloch’s Toolbox (2/​2)

  Meta-problems in general [...] are issues outside the Overton window.

  Does anyone have a theory about why this is the case? Thinking out loud:

  • voting systems: I guess any mention from a politician would be immediately dismissed as agenda-based. And well, probably any mention from anyone. Making changes to political systems also has a Chesterton’s fence component: we know how our system behaves, we don’t know how this new system would behave, and we know from history that we should be quite happy to have political systems that kind of work and haven’t already led us to totalitarianism. I’m not sure this aspect contributes to making these ideas outside of the Overton window, though.

  • academic science being focused more on prestige than on producing knowledge: it’s about prestige and social status, which are a bit taboo? Fear of fueling science deniers? Respectable newspapers have themselves been pursuing prestige for decades?

  • other relevant meta-problems?

  In general, if you talk about changing the rules of the game you’re playing in your personal career, you’ll be dismissed as making up new rules just to get an edge; if you talk about rules you’re not playing, you’re not an expert.

  Any thoughts?
