A thing I didn't realize would be a consequence of making a niche podcast is how much podcast spam email I get. Mostly of the form "bring my client as a guest on your podcast", sometimes of the form "use our social medium" etc. Examples that I've received in the last ~week at the end of this post.

IDK maybe this is unsurprising given that podcasts have an email attached to them. Interestingly it does seem to happen more now that my podcast is more prominent than it was ~2 years ago.



AXRP Episode 36 - Adam Shai and Paul Riechers on Computational Mechanics


I made an episode about computational mechanics and I think it's cool and you should watch (or listen or read as the case may be)!

Transcript

Blurb I wrote:

Sometimes, people talk about transformers as having "world models" as a result of being trained to predict text data on the internet. But what does this even mean? In this episode, I talk with Adam Shai and Paul Riechers about their work applying computational mechanics, a sub-field of physics studying how to predict random processes, to neural networks.


ToC if that's interesting:
- 0:00:42 - What computational mechanics is
- 0:29:49 - Computational mechanics vs other approaches
- 0:36:16 - What world models are
- 0:48:41 - Fractals
- 0:57:43 - How the fractals are formed
- 1:09:55 - Scaling computational mechanics for transformers
- 1:21:52 - How Adam and Paul found computational mechanics
- 1:36:16 - Computational mechanics for AI safety
- 1:46:05 - Following Adam and Paul's research

Fun facts:
- I recorded this episode 3 months ago to the day - one of my longest publishing lags ever, in large part because of being busy with MATS.
- Some of the stuff we discuss got worked on during MATS.
- IDK I think this episode is pretty cool.

"soft inbox zero"

Ben Millwood
I am guessing nobody checks emails more than a week old.


oh I definitely do! sure the value drops off over time, but I think for some things like "someone posted on a substack you subscribe to", reading it a year later isn't necessarily much worse than reading it in real time

I do think it makes sense to archive e-mails once you're like "even though there's something here, realistically I'm never going to do it", but I also think quite a lot of those things that you should have done some embarrassingly long time ago are actually still worth doing today



Kopia as encrypted backup provider?


Anyone have takes? Things I want:
- Encrypted backups, on my external hard drive + backblaze b2 (seems like it checks this box)
- Basically a reliable operation that's going to continue to exist, fix bugs, etc.
- Works nicely when people try to restore from backups.

Their website

in reply to Daniel Filan

I've been using restic (with B2) for ~6 years with no hiccups, including restoring in anger once (i.e. my local drives died). Kopia is newer and less popular; I don't see much reason to use it over restic unless there's some specific feature you want, though I also don't know of any particular reason not to use it.

(Restic's crypto has been informally reviewed by a cryptographer, who concluded he'd use it for his own backups; no idea what the state of Kopia's crypto is.)

in reply to Daniel Filan

I did not on purpose do the thing where you confidently say a wrong answer to get people to tell you the right answer but I'm glad that effect seems to have worked in my favour.



looking like I'll get credited as bug reporter for a Linux btrfs bug: patch and bug report

this is silver lining on how it has become harder over time for me to whole-heartedly recommend btrfs, especially to "ordinary" Linux end users... I think I'd still do it on balance? But I'd say a backup strategy is not optional. (But maybe I'd say that anyway.)

see also: my backup strategy

in reply to Ben Weinstein-Raun

zfs has a couple of its own bugs that I've run into, e.g. bad handling of unplugged usb and terrible zfs diff performance. I don't feel super opinionated between them. zfs is a bit more aggressive about managing mount points and options instead of doing it via system configuration, which you might take as a good or bad thing. I find btrfs snapshots a bit more convenient to work with (they're just there on your disk, whereas with zfs I think you need to clone them to a new FS first or something)
in reply to Ben Millwood

Looking around on the internet for other issues just now, it's also apparently pretty common to run into showstopper bugs when trying to do zfs send or zfs receive on encrypted zpools. I've never tried it but that does seem pretty bad.

And yeah, that USB issue sure looks annoying :/

in reply to Ben Weinstein-Raun

Do you mean only with the native encryption? I use LUKS and I imagine it can't even tell I'm doing that?
in reply to Ben Millwood

yes, sorry, specifically with native encryption. afaik you're right that it doesn't know if it's running on top of LUKS
in reply to Ben Millwood





It's pretty relieving that, in the context of Friendica, I don't have to worry that links in the post get penalized by the ranking algorithm.


Is it just me or are some names "more meme-y" than other names? Like, Eliezer Yudkowsky. Very meme-y name. I feel like a name that meme-y is a genuine asset. Leopold Aschenbrenner. Also very meme-y.

Ben Weinstein-Raun? Hard for me to judge, but I'd guess middling meme-y-ness at best. Benjamin Weinstein-Raun seems at least a little meme-y-er. Should I start going by Benjamin in professional / semi-public contexts?

in reply to Ben Weinstein-Raun

This inspires me to ask, how do you pronounce your surname? (I'm particularly unsure about the Raun part, but I guess the other part could be wine-steen or wine-stine). Names are more meme-able if people know how to say them, arguably. But then again, few know how to say Eliezer Yudkowsky when they read it for the first time!

I think my full name of Amber Dawn Ace is very meme-able, to the extent that people assume some part of it was chosen by me, but actually no, the first two were chosen by my mum and the third is the surname she was born with.



If you use Linux or FreeBSD and aren't paying attention today, there's an unauthenticated remote code execution vulnerability in CUPS. If you use Linux or FreeBSD, especially for a desktop or laptop computer, be sure to disable CUPS or see if you can update to a version with fixes for today's CVEs.

Replacing one mental question with another by mistake


As part of career reflection, I’ve been regularly trying to answer questions like ‘what’s your gut guess for what you’ll be doing this time next year?’. Today I noticed that my brain, casting about for the answer, was trying to instead answer the question ‘what do you feel most excited about doing?’, which is obviously different. I mean, maybe related, inasmuch as I am quite an excitement-driven person and maybe being excited about something does make me more likely to do it in future! But still.

Anyway, I feel like I once read a blog about something like this: accidentally replacing one mental question with another by mistake. It was probably by a rationality-sphere person. Anyone know what I’m talking about?



Flowers for Algernon: the two most weepy bits


“You’ve done so much with so little, I think you deserve it most of all” — the kind-hearted literacy teacher of the intellectually subnormal protagonist, who wants, more than anything, to learn and be ‘smart’.

“I don’t think it’s right to make you have to pass a test to eat” — the kind-hearted intellectually subnormal protagonist takes pity on the experimental mouse having to solve ‘amazeds’ to get food, unaware that he is describing his own plight as a very low-IQ person in a human society that has only the most threadbare of safety nets.



looking for recommendations in:

  • open-source server monitoring software (things like "e-mail me when the server is down", "e-mail me when the server is about to run out of disk space", and I guess optionally things like "record, store, and graph metrics like CPU and memory"); there seem to be a lot of options out there but I'd be interested in hearing anyone's personal experience
  • open-source issue tracker software -- similarly, there's a ton of them and I'm interested in hearing which ones people have had good experiences with. I'm mostly a minimalist here, with the exception that I want to be able to create ordered lists of issues (like GitHub projects).
in reply to Ben Millwood

btw, I've also spent a bunch of effort looking for decent issue trackers (open source or not) and have basically never found one that I like. FogBugz in 2006 or something was my favorite for a while, but I think at this point I'd find it limiting. So, if you find one that you like, I'd definitely be interested in hearing about it.
in reply to Ben Weinstein-Raun

very briefly looking over that list, I notice two entries that I don't remember evaluating that seem potentially promising: Request Tracker and Mantis BT.


Science demos


I've been curating a list of interesting science demonstrations one could do at home with only relatively small investment of time and money. For example, did you know you could make a cloud chamber sufficient to see tracks of cosmic rays using just some dry ice, alcohol, and craft supplies?

I've tried to be reasonably thorough without sacrificing quality, but I'm sure there's some good ones I'm missing. Any favorites?

writing.bakkot.com/science-dem…

in reply to Kevin Gibbons

I have only done a small fraction of these myself but I'm going to make a sincere effort to work through as many as I can with my kid/kids. I feel like a good science class should have a lot more of this stuff and significantly less memorization. You can memorize stuff once it's motivated, not before.
in reply to Kevin Gibbons

These are great! Some things that come to mind:

in reply to Ben Weinstein-Raun

Ooh, nice. The water boiling one is especially great; will add. (I love AlphaPhoenix; gotta binge the rest of his stuff at some point. Already have at least one of his other videos on the page.)

Added both! The first as just a note on the existing Schlieren section. Let me know if you come across any more.


For anyone following me, you can also follow me on Mastodon @Alex Altair. You can do this right from your Friendica account! (But also from a Mastodon account.)

I really like that sometimes things get better over time. From 2016 - 2023 I fairly often did research to try to find the best indoor air quality monitor, and even though in principle it would have been very easy to manufacture something great, the actual competitors all sucked.

But I moved into a new house recently, and looked again; there's now at least one really good option: the QingPing Air Quality Monitor Gen 2.

Maybe it's spying on my for the Chinese government or something and that's why it's so good? But it has a pretty nice UI, measures ~all the relevant things (PM2.5, CO2, VOCs, humidity, temperature), and has an app that logs 30 days' worth of measurements. It's not cheap, but it is a bit cheaper than the similar things I'd bought for the purpose that were also substantially worse.

in reply to Ben Weinstein-Raun

you're not responsible for how I spend my money :P was just curious in case it was a bug rather than a feature
in reply to Ben Millwood

it's also possible I was just generically not sleeping and the little fan noise was a misdiagnosis, turning it off did not immediately solve my problem


today's shower thought: among spherical, flat, and hyperbolic geometry, flat space is the only one where geometry is scale-invariant. so it's the only one where you can have scale models of things! it's the only geometry that can support Warhammer 40k and that Zoolander joke about the centre for ants

Ben Millwood reshared this.



"Why do mirrors flip text to be right-to-left, and not top-to-bottom?"


in reply to Ben Weinstein-Raun

Honestly, the part where I see myself as being left-right switched rather than up-down switched still feels confusing to me in this frame.
in reply to Ben Weinstein-Raun

Like, if I think it through all the way, I can see why I am actually mentally privileging the vertical axis, but it's hard to get my system 1 to understand this.

Ultimately I think the biggest thing is that humans are roughly bilaterally symmetrical but not top-bottom symmetrical, and my guess is that this is sufficient to do the symmetry breaking. Like, if you parity-flip me, I still visually "make sense" as a left-right-swapped person, but I don't "make sense" as a top-bottom-swapped person; people don't have their heads on the bottom.

in reply to Ben Weinstein-Raun

So there are at least two interesting thought experiments about putative zero-g humans:

  1. What if humans were radially symmetrical? and
  2. What if humans had no visual symmetries at all?
in reply to Ben Weinstein-Raun

I think non-symmetric people in an environment that has gravity might still perceive mirrors as flipping things left-to-right. As we've established, it isn't that the mirror flips things, it's that you flip things when you turn them to face the mirror (or you imagine them having flipped when they face you in the mirror), and so the question is "what is the default way to flip things?". And I think in the presence of gravity, it's most natural to use the direction of gravity as your rotation axis, so that e.g. your mirror self's feet are still on the ground.
in reply to Ben Weinstein-Raun

Yeah, I was about to say the same thing about bilateral symmetry.

Another thing I just realized is that if I look at a mirror on a ceiling it intuitively feels like it's reflecting across the mirror and not switching left/right.



Plasma lighters are neat


Recently I was thinking a bit about updating my "bug out bag", especially thinking about including more ways to start a fire on top of just having a bic lighter. I looked around online for other fire starting tools, and learned about electric plasma arc lighters, which I had never heard of before.

Naively, it seems like a really great alternative to a traditional lighter:

  • no expendable fuel; any source of electricity can serve as fuel
  • about as easy to use as a regular lighter: slightly less hot surface area, but in exchange you get push-button activation and no difficulty positioning the flame to avoid burning yourself
  • very resistant to wind
  • iiuc, should work even in very cold temperatures where butane lighters struggle

I tentatively think these things are great. I don't know:

  • how long one full charge lasts
  • the operating life of the battery
  • whether the arc contacts wear down over time

If those considerations compare favorably with bics, I think these lighters might strictly dominate traditional lighters for a primary emergency fire source, excluding cost. Plus they look really cool.


in reply to Daniel Filan

I have a vague sense that this is satirizing something specific that I haven't read.
in reply to Ben Weinstein-Raun

@Ben Weinstein-Raun some combo of "our mathematical universe", fractals, string theory, and sabine hossenfelder. Basically just making fun of theoretical physics popularization.


Tired of all the little dishonesties


in reply to kip

I strongly agree with this.

Also, if you happen to be wanting to give me feedback, I highly encourage this, of course including having an anonymous feedback form (link in profile).

A thing that helps me with a million communication annoyances, at least when both people are used to using it, is the idea of generalized happy prices: to express the magnitude of a preference, just say how much money you'd be happy to pay for that preference to be satisfied, or what amount you could be paid in order to feel overall happy about the trade, even if the preference isn't satisfied. Sometimes money can actually change hands to make everyone happy; sometimes not; but at least it helps to get across preference strengths.

Paying bounties for links to AI-related evidence

not serious evidence for any of the claims but I figured you'd appreciate it. Humans are apparently very easy to use as actuators.


It's weird that candidates' use of alcohol isn't more of a campaign issue. I mean I guess it's not weird because most people drink alcohol and don't like the idea of implicitly being judged for doing so. But all else equal, it really seems like it would probably be better if the leader of the free world largely refrained from intoxication.
in reply to Daniel Filan

I feel like this probably wouldn't affect my vote in a Presidential election, but I could totally imagine it affecting who I would vote for in a primary.
in reply to Daniel Filan

I wonder if it's just a thing that Republicans are more likely to abstain. Seems so based on Presidential candidates since 2000 but that's a small sample size.


I find this first Gumby TV episode way more strangely compelling than most things I've seen from its era (1956). It's very unpolished; some frames even have visible hands in them. I wonder how they made the spacey soundtrack.

Cool ~linguistics fact (maybe this could be my brand)


This is adapted from Wikipedia.

In 2011, the Welsh author Roger Bryan discovered this poem written at the bottom of a page of saints' days within a Latin manuscript in the British Library's Harleian manuscripts. He dated the entry to 1425 ±20 years.

Thirti dayes hath Novembir
April June and Septembir.
Of xxviij is but oon
And alle the remenaunt xxx and j

Seems like they're rhyming the word 'one' with itself ('j').

Note that November is taking the place that September does in the modern rhyme. The early versions tended to favour November and as late as 1891 it was being given as the more common form of the rhyme in some parts of the United States.

The unhelpfulness of such an involved mnemonic has been mocked, as in the early-20th-century parody "Thirty days hath September / But all the rest I can't remember."

Overrated:
- Marcus Aurelius
- "Saint" Augustine of Hippo (are the haters Eastern Orthodox or atheist?)
- Cleopatra

Underrated
- Justinian I (who dislikes that guy?)
- Cicero

in reply to Daniel Filan

Cicero adapted the arguments of the chief schools of Hellenistic philosophy in Latin and created a large amount of Latin philosophical vocabulary via lexical innovation (e.g. neologisms such as evidentia, generator, humanitas, infinitio, qualitas, quantitas), almost 150 of which were the result of translating Greek philosophical terms.


In this house we respect lexical innovators (except for my irrational (?) dislike of the Lightcone Hyphen).



So the UK progress people have put out a new report about how it would be good if investment and building things were legal. And it's all good, and it makes sense that they're writing it, but I don't feel super hopeful. Maybe this is one of those things like Sonja Trauss founding SFBARF and hopefully 5 years later something comes of it?


If I got to choose one thing to change about American public schools, my first thought would be to introduce basic economic concepts as a subject with the same weight as civics.

The near-universal lack of econ understanding seems to me to underlie many of the worst aspects of current political discourse.

This stuff seems much more important for most people to understand than trigonometry or chemistry.

in reply to Ben Weinstein-Raun

I would also change this about UK state schools, for whatever that's worth


Camino Day 12


A good grade in pilgrimage is both normal to want and possible to achieve.

As planned, this was a short day. The final 15km to Santiago de Compostela are unremarkable except that you can feel the excitement of the other pilgrims.

I only spent a little time in Obradoiro Square before I was occupied with other concerns: getting breakfast, charging my phone, getting out of the encroaching rain, checking into my hostel, submitting my Credential.

I'm not a spiritual person but the past twelve days have been challenging and beautiful and intense. I've tried to reflect on how I connect with people, how I meet challenges and how I use my gifts. None of that has solidified into any great revelations; just a collection of moments.

I'm going to get a real hotel room for the rest of the trip though, as a treat.

Here's a pedantic remark to make my first contribution on this website: These appear to be arthropods, rather than fish. The first appears to depict a lobster or crayfish, the second and third pictures appear to depict horseshoe crabs, and the fourth picture is unrecognizable to my eye. Fish are considered to constitute all vertebrates minus the tetrapods, whereas arthropods are invertebrates, and a type of protostome.
