Hi. I'm Gareth McCaughan. I've been a consistent reader and occasional commenter since the Overcoming Bias days. My LW username is "gjm" (not "Gjm" despite the wiki software's preference for that capitalization). Elsewehere I generally go by one of "g", "gjm", or "gjm11". The URL listed here is for my website and blog, neither of which has been substantially updated in about the last four years. I live near Cambridge (UK) and work for a small technology company in Cambridge. My business cards say "mathematician" but in practice my work is a mixture of simulation, data analysis, algorithm design, software development, problem-solving, and whatever random engineering no one else is doing. I am married and have a daughter born in mid-2006. The best way to contact me is by email: firstname dot lastname at pobox dot com. I am happy to be emailed out of the blue by interesting people. If you are an LW regular you are probably an interesting person in the relevant sense even if you think you aren't. If you're wondering why some of my old posts and comments are at surprisingly negative scores, it's because for some time I was the favourite target of old-LW's resident neoreactionary troll, sockpuppeteer and mass-downvoter.

Presumably the result of a coproof is a cotheorem. Which I mention only because, as everybody knows, a comathematician is a device for turning cotheorems into ffee.

For what it's worth, I read Benquo as saying not "Qiaochu is trying to do this" but something more like "People who see rationalism as a cult are likely to think the cult leaders are trying to do this". Though I can see arguments for reading it the other way.

Neat. Er, are the "User" and "Deleted by user" columns meant to be the same? Because it seems like they *are* the same but I'd have expected the former to contain the name of the user who *posted* the thing-that-got-deleted, not the name of the user who deleted it.

I think you have misunderstood at least one thing: P0 and P1 are _definitely both true_. (They are propositions of the form "there are imaginable states of affairs such that ...".)

Once again, I don't know very exactly what Harris and Klein have said, so I can't easily tell what if anything he's do...(read more)

All this discussion seems insufficiently specific to make actual progress.

Obviously there are imaginable states of affairs in which our best estimate of genetic differences should be very close to zero. (E.g.: Observed overall differences small, many environmental effects found and well understood...(read more)

To me, (1) "coupling" suggests specifically joining _in pairs_ much more strongly than "decoupling" suggests specifically detaching pairs and (2) "coupling" suggests that the default state of the things is disconnection, whereas "decoupling" suggests that the default state is connection.

Continuing attempts on WSL under Windows 10. I killed the bash prompt I had, and started a new one. This now seems to find the correct version of npm in preference to my Windows one, and _npm install_ no longer fails instantly.

Unfortunately, it does still fail. After downloading a bunch of things,...(read more)

I don't think it should be at -17, but I don't think what its low score indicates is that LW has a problem with people who want to do advanced things.

Your suggestion, taken as a serious one, is _obviously absurdly overambitious_. Its premise is that the experts in the relevant fields have nearly e...(read more)

For what it's worth, I didn't downvote it. I wasn't sure enough of what it's trying to achieve to be able to tell whether it succeeded or failed, or whether I approve or disapprove :-).

What's the point of the comment above? I mean, presumably you don't actually think that's a sensible goal for anyone to have, because no one could think that, so I guess the purpose is mockery or something of the kind -- but if so, presumably there's some point beyond mere mean-spiritedness, some ac...(read more)
