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.

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.

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.

Something really wild to me is the extent to which archaeology seems to believe that artifacts were used for some kind of religious / worshipful purpose.
Like, in the modern world, relatively very very few objects are used for worship. If a future civilization finds a figurine, it's probably a Barbie doll or a Funko Pop or something.
Future civilizations might find our most treasured artifacts and presume that we worship glass rectangles or something.
Seems kinda weird if this is the default assumption for unexplained historical artifacts, as it naively appears (to a non-archaeologist). Like, why do we think that these figurines are fertility goddesses rather than toys or instructional tools or even pornography?

I contend that we do worship glass rectangles.
Nobody thought Christianity was a 'religion' when it was dominant. They thought of it as 'the way things really are' and no one described it in terms of religion.
Our current 'secularism' is also a 'religion' in this same way. We don't see it as religious activity to go to a supermarket or post on Facebook. But ... it is?
> Nobody thought Christianity was a 'religion' when it was dominant. They thought of it as 'the way things really are' and no one described it in terms of religion.
FWIW I don't think this is true. If you want to talk about the New Testament authors, the last bit of James 1 seems to talk about Christianity as a religion, James and Paul talk a lot about "the faith", Hebrews 11 talks about faith as belief in things unseen and seems to indicate it's a good thing. The proceedings of the Council of Trent talk about "the Christian Religion" (e.g. history.hanover.edu/texts/tren…).
[I mean TBC they also thought it was "the way things really are"]

Hmm lemme clarify.
RE: 'Religion' as 'worldview you can select into or out of' -- at the time of Christianity's dominance (which wasn't until much after New Testament being written anyway), no one thought of Christianity as a worldview. They thought of Christianity as the way things really are.
"Religion" was more like those pagan traditions that you could opt into or out of but were clearly wrongheaded, outdated, nonsensical, and everyone knows are made up. That's what I mean.
Now we use 'religion' in the same way, without recognizing that our dominant worldview is also a religion in fact.
FWIW this wasn't clear from the way I wrote things up but the Council of Trent was held in the 16th century as a reaction to Protestantism. People at the time really did use words like "faith" and "religion" to describe Christianity, altho I'm not sure they would have said you could opt out of it or that it was made up.
At any rate, zooming out, I feel like we can drop the word "religion" and there's still an important thing here. My understanding is that most religious practitioners think that there's something importantly different about the rituals I'd be tempted to call "religious" (e.g. going to mass / church service, sacred artwork, etc) and stuff I'd be tempted to call "secular" (e.g. drinking a can of soda, going on my phone), even when they think mass / sacred art is super important and real. So there's still a live question of "was this pot related to by people back then more like the way believers relate to sacred artwork, or more like the way believers relate to cans of soda".

Recently I've had some physical issues that have kept me from being physically active (not that I'm usually very active, but this has been even worse than normal):
- About a month ago I learned I have a hernia after doing some wood-chopping (which is really fun btw), and I've been having an upsettingly difficult time setting up an appointment for surgery to fix it
- A week after that, I broke my pinky toe by accidentally kicking a staircase in the dark
The hernia has kept me from feeling good about doing any kind of weightlifting, and the broken toe has made it hard to walk more than a few blocks. This kinda sucks and I'm not sure what to do about it.
Maybe I should be cycling more? Anyone have other ideas?

Do y'all remember that princeton election guy who forecast a win for Clinton with 99% in 2016? I just found a post-mortem interview with him where he says:
Probabilities are not a good way to convey uncertainty. The first reason being that it’s hard to estimate the true amount of uncertainty, and I discovered that.
I... have never before felt such a strong urge to say "skill issue". But people weren't saying "skill issue" yet in 2016, so nobody got the chance. Time is cruel.

Sam Wang and Nate Silver had an interesting back-and-forth, if I remember correctly. A friend of mine was convinced that Sam was right and that Nate was “putting his thumb on the scale to cover himself.”
In hindsight, it seems to me that Sam’s approach was more of a straightforward averaging of polls, while Nate’s method is more like a gambler’s—integrating his own beliefs into the model.

This seems like it's making progress towards a formalization, though I think it still struggles.
If you imagine that covid virons were agents, then it seems to me that although there's a sense in which we're much more powerful than them, and you know, humanity could, if "it" wanted, defeat them, they can kinda get what they want without enormous costs to humans. And yet humans are still much more powerful than covid virons.

Hosting providers
Right now superstimul.us is hosted on a Vultr VPS instance. I use Vultr because it's a decently reliable VPS host that offers OpenBSD (though this instance is running in Docker on a Debian system). Much cheaper than AWS; comparable pricing and features with many other VPS providers.
But I just went looking at the prices of competitors, and Hetzner is cheap. How is it so cheap? For roughly the same price I'm paying for this host, I could get ~8x the vCPUs and RAM, and 4x the storage.
It would be a hassle to migrate at this point, but I'm definitely tempted.

1. It's *even more* cost-competitive if you participate in their dutch-style server-capacity auction (a neat idea):
- hetzner.com/sb/
- docs.hetzner.com/robot/general…
- There is also open-source tooling to automate interaction with the auction.
2. Have no illusions that such infrastructure is physically secure against interference (fun example at: notes.valdikss.org.ru/jabber.r…), and account for such in your threat model if/as appropriate.

Notes on the outcome of groups experiment
I think groups are a pretty half-baked feature, and I don't expect people to use them much. A "group" (previously called a "forum", and most of the documentation hasn't been updated to reflect this change) is basically an account that auto-reshares things it's tagged in. You can give it a few different settings for how it responds to follow requests, and another setting for the visibility of its reshares. To administer a group, you have to create a second account for it (which friendica does make relatively easy but not trivial), and then switch to being logged-in "as" the group.
So, yeah I guess it might be useful for coordinating things somehow, and the setting with private reshares is maybe promising (though also marked "experimental"). But it seems much less natural to me than the corresponding concept on Facebook.

Some praise for the behind-the-scenes tech I'm using to run this site
- Tailscale: Lightweight personal VPNs. Tailscale is so good. I don't even need to have an open ssh port on the VPS running this instance, because I can connect over tailscale SSH with zero hassle.
- Caddy: Caddy is like nginx if nginx cared about usability. e.g. it makes it trivial to put an HTTP service behind a TLS proxy. Like, it even manages the LetsEncrypt certificate for you. Totally wild.
- Docker, and the official Friendica images especially: I hate developing for containers, and avoid it when possible. But when someone else has put in the effort to make a high-quality container image, deployment is genuinely much easier, even for hosting the thing on a VPS.

The plan for the beta
Thanks to everyone who's joined to help beta test! I'm very grateful y'all are here! ❤️
My basic plan is to use superstimul.us for the next week, posting here instead of Facebook, getting a sense of the platform so that I can help other people later, and trying to iron out basic issues if they crop up.
After that, I'm going to do a push to invite clusters of people who I'm especially excited about being here. I'll probably reach out to y'all for names of people who are cruxy for your active enjoyment/participation here (feel free to preemptively message me about this!).
Anybody can invite their friends, btw, though I would slightly prefer you held off for now, because I want to be strategic about the launch.
I might do some kind of incentive / costly-signaling scheme where I give $20 or so to the first 30 people who share a substantive post here, and not on other social media? Or something; Not sure about that yet.

I'm really excited for this experiment! Friendica exceeds my expectations in some ways (looks nice, has imo an especially good privacy model, seems easy to update and administer) and falls short in others (ease of finding people, occasional UI weirdness).
Please let me know if you run into any issues and I'll try to fix them or at least help resolve them

in reply to Ben Weinstein-Raun • • •This is a thing I've thought a fair bit about in a caving context. It used to be the case when everybody still used carbide lamps that your source of light also doubled as a meaningful source of heat. It was standard practice to carry a trash bag (often in the void space in suspension helmets) which, if you were cold (at risk of hypothermia) you could simply take out, rip a whole in the corner and pull it over your head (head sticking through the whole, so you can breathe, but it traps heat around your body), and then put your carbide lamp also under the trash bag, and your body quickly becomes warm. A trash bag big enough to crouch inside were ideal (50 gallon drum liners seemed to be a common recommendation).
LEDs and batteries have totally surpassed carbide lamps from a lighting perspective, but the secondary/incidental free hypothermia-mitigation property is still an overall property worth satisfying somehow. Candles, and some way to light them, are a reasonable thing to carry.

Matches aren't great: they break, they're unreliable when wet (even fancy "waterproof" ones seem to be), need a suitable striking surface (even fancy "strike-anywhere" ones).
For normal BIC-style lighters, you also need to be concerned about accidental button depression leading to fuel loss, meaning you need to pay attention to how you're storing it. You can also find little O-rings of the right size that can fit on just under the button and make it harder to get accidentally press. You can also find little rubber covers that fit over just the "business end" of the lighter, to protect its mechanism and make it harder to accidentally depress / leak fuel in storage.
A plasma lighter would need to be at least as durable and reliable as a BIC. However, bonus points if it works on 18650 cells, as those are almost always available (and charged!) due to their service in headlamps as well.
A reliable plasma lighter driven by easily-accessible 18650 cell would then seem rather appealing, as, at least in a cave context, one would be virtually guaranteed to have power for it, and the marginal weight of carrying it should be thought of as not including the battery because you're probably wanting to carry extra 18650 cells anyway, at which point the lighter could be thought of as just a fancy 18650 carrying case, whose battery-contents could still be put to other use as needed.
Some additional points in favor of normal lighters over plasma lighters:
1. Can be used to melt low-melting-point materials, such as to fuse the ends of most ropes to prevent fraying.
2. If I have an unrelated source of fuel, such as a camping stove for cooking / boiling water / personal heat in a pinch: If the stove doesn't already have some kind of piezo-igniter built-in, even just the spark from an otherwise-dead (out of fuel) BIC-style lighter can be enough to ignite the other fuel source.
3. Of limited utility, but something I have actually experienced: Lighters that require oxygen to function properly are useful as indicators of low-oxygen environments. Granted, if you're concerned about bad air, low-oxygen isn't the only thing you need to worry about, and if that's a concern you probably want better ways of monitoring it, but where not expected, it's a better than nothing. On the other hand, anecdotally, it may be counterproductive, as people seem more likely to attribute a BIC-style lighter appearing to malfunction to be due to lighter malfunction than a true low-oxygen hazard, even when the latter is the actual reason, especially when judgement and reasoning may already be impaired due to hypoxia. which is it's own thing.
Then, as far as what to light (and burn for heat): Beeswax seems to have the best energy density (in terms of J/kg) of readily-available materials in its category, is fairly cheap, and readily available in candle form. (If anyone is aware of a higher energy-density material which could be made into a candle with similar safety, stability, etc. properties, however, I'd like to know!)
