justinpowers··on A suspiciously criminal portfolio website
I often open the fridge to find it packed with vegetables, fruits, eggs and other healthy ingredients. I then close the fridge, about 2 minutes later, still empty-handed and still hungry, saying aloud to myself and to whoever will hear…

      ”There’s no food!”
So, I completely understand.

“Feature” can mean “physical beauty” as well as simply “appearance” or “form”, though all such are considered obsolete usages.
justinpowers··on Is tipping getting out of control? Many consumers say yes
This may just be a side-effect of the insurgence of new POS systems and customer-facing systems.

Many of the newer POS systems were first developed with the hospitality industry in mind. In those cases, tipping is on by default. These POS systems have since expanded into retail and convenience stores, leaving tipping on by default. The shop owners have little incentive to turn it off, or may not even know how to turn it off.

Additionally most older POS systems were not operated by the customer and so did not display set percentages. They relied upon manual input based on a signed receipt. So percentage norms were mostly word-of-mouth. Nowadays, with customer-facing POS systems, it’s easier to just provide a percentage button. And the owner or manager or even the lowly register attendant, can adjust as needed. And of course, higher defaults are better for all of them (within reason).

Most POS systems do not charge per transaction, neither by count nor dollar amount. It’s usually an upfront or flat monthly fee, based on number of terminals, level of service and feature set.
justinpowers··on Ask HN: Alternatives to The Economist?
I agree. But I optimistically believe that decline will soon experience a renaissance.

We’re gonna start declining again. We’re gonna decline so much. We’re gonna decline at every level. We’re gonna decline economically. We’re gonna decline with the economy. We’re gonna decline with military. We’re gonna decline with healthcare and for our veterans. We’re gonna decline with every single facet.

We’re gonna decline so much you may even get tired of declining. And you’ll say “Please! Please! It’s too much declining! We can’t take it anymore. Mr President, it’s too much!”

And he’ll say “No it isn’t. We have to keep declining. We have to decline MORE! We’re gonna decline MORE! We’re gonna decline so much! I love you America. You’re gonna be so happy!”

Ahh yes. Soon. Soon.

justinpowers··on Psilocybin microdosers demonstrate improvements in mood and mental health
There are absolutely risks, but not to the degree that op's comment suggests.

If one is worried about a microdose, then one can choose to start with 1% of a microdose (or whatever minimal amount one can accurately measure) and then move up slowly.

Just like...exercise. Hence the forever present disclaimer: "Consult with your doctor before beginning this or any new exercise routine." One wouldn't start off with an ultramarathon when they could just walk around the block.

If, on the otherhand, you believe that _any_ amount is a risk, then at this stage it's up to you to provide that evidence. This isn't some new and mysterious chemical, it's been taken for millenia, intentionally or not.

The bigger issue is that people just assume that they don't need guidance or preparation. Or they ignore set and setting. Or they believes there's only one right dose or no such thing as a wrong dose. Or they simply don't know the dose because it's in whole mushroom form. And so they just take whatever they're told and then wait to see what happens.

These are where the risk comparison between exercise and psilocybin breaks down, because if you do make a mistake, you cannot abort the process as easily as you can with exercise. Once you've taken it, you're in for the ride.

But that's quite different from "it messes with your brain".

And thus exercise “messes” with your brain as well. For consistency, you should probably steer clear of that too.

Trying to find more on this. Do you have a link or a good search term to point me in the right direction? (Specifically regarding affecting individual cells; brain state biofeedback overwhelms the search results)

justinpowers··on The most livable cities
Most “walkability” scores either directly or indirectly account for crime. For instance, residents rate walkability and are specifically asked to consider crime and safety. Or, conversely, walkability is measured based on the number of actual walkers and the number of walk-accessible amenities in a given area.

High crime areas would naturally have fewer walkers and fewer amenities.

I can’t speak to Baltimore, but in Chicago, crime and scarcity of amenities go hand-in-hand. I can’t think of a single pedestrian-focused area that has both amenities and a significant crime problem (one must understand that Chicago crime is not nearly as prevalent or evenly dispersed as the media and non-Chicagoans enjoy imagining).

justinpowers··on The Nature of the Firm (1937)
This is very interesting. Similar to a path I almost went down with some partners, but it fizzled due to too many unknowns and lack of energy to research them. Would you be willing to expound on your arrangement? Either here or privately. In particular…

What legal structure are you each using? sole proprietorships, llcs, s-corps? (Assuming you’re US based)

Are there any tax benefits/costs to this arrangement?

Has the government hassled you regarding the arrangement? (It sounds like it has, but…how exactly and how did you respond?)

Have counterparties hassled you or been scared off? Do they even “know” of the arrangement?

Are there significant legal/transaction costs between the three of you? If not, is that simply because you have strong trust in each other?

No sugars might have been better said as “less sugars” for the pedantic amongst us.

Never said there was no mechanical cleaning. But they certainly didn’t have our “advanced” toothbrushes, toothpastes and mouthwashes. In fact, I’d say “mechanical washing” was an unavoidable aspect of eating harder foods rather than the soft, sticky processed items we tend towards today. And furthermore, with less stickiness (gluten and sugars) they would have needed less mechanical washing.

Anyways, lifestyle changes don’t need to be all or nothing to have a measurable effect

And yes even good bacteria can/will be bad at some point. Nonetheless they are still better than most others and will help maintain homeostasis for as long as time allows. We haven’t yet found a cure for time-related degeneration/accumulation, have we? But again, maybe I should have said “better bacteria” rather than “good”

justinpowers··on Results from first US trial of genetically modified mosquitoes
There’s good (and bad) bacteria all over our bodies. Our skin is coated with them and needs to be coated with them. Without the good ones on our skin, bad ones take over, and then any cuts become more likely to get infected.

I’ll update later with a source reference or two. But I’m willing to bet that Wikipedia‘s “skin flora” page has good info. Im not sure of the term for the mouth’s flora though…but I have zero doubt that it exists, simply because bacteria is everywhere. And gut bacteria get there via the mouth.

Long story short, there’s no such thing as a pure human. We exist only because we are colonized by bacteria. We’re kind of like the earth in that regard. We house living organisms and they make us what we are, without them homeostasis crumbles and so do we. So, with that in mind, we should be selectively helping the good ones and killing the bad, instead of wiping them all out.

Regarding replacing the gut bacteria with suitable enzymes for digestion, that would probably be misguided. The bacteria do more than just help digestion… they also keep bad bacteria out. And furthermore, they actually affect our mental health, keeping depression at bay for instance. Whether that’s indirectly via suppressing inflammation or some more direct means, I don’t recall.

Edit: Looks like it’s a much more direct means of influence: https://news.ycombinator.com/item?id=31100533 (There doesn’t seem to be much about this here on HN already, so I’m providing a source via HN submission in hopes of generating some discussion…)

You jest but you’re wiser than you realize, especially if you include a diet change as part of the driver.

Good diet (no sugars) and avoidance of broad-spectrum bactericides will allow good bacteria to thrive, pushing out the bad smelly ones.

People have noticed similar beneficial responses, ie lack of disgusting body odor, when quitting hot soapy showers or the use of antiperspirants.

Just gotta make sure diet goes with it. Along with general common sense cleanliness.

justinpowers··on Where in the galaxy will we mine lithium?
Haha clever, and I guess this technically counts as living “on” Pluto, albeit a deconstructed Pluto.
justinpowers··on Where in the galaxy will we mine lithium?
Whether it’s acknowledged or not, “real” nature is all around us, everywhere, in a way that Pluto could never mimic unless of course humans magically terraformed it into existence, or some illusion of it.

It’s odd how easily we forget the simple things, like having a blue sky and a distant horizon. Or feeling the pull of the earth beneath our feet. Or the myriad of subtle scents in our nose, that immerse us even when we are unaware of them.

A little searching online will find you plenty of studies that show how nature, both simple and complex, reduce mental stresses in humans.

It seems prudent to at least assume that the environment in which we arose and for which we are adapted, would be not only better suited for the human body but also for its mind.

As a starting point for research into the effects of a similar, but still far more “natural”, environment: https://en.wikipedia.org/wiki/Winter-over_syndrome

All that said, I suppose it’s possible that humans born on Pluto might fair better. We probably (hopefully) have very few case studies that could even begin to provide some insight into such a scenario. So who knows…

justinpowers··on Security experts declare all Proton apps secure after security audit
So many complaints about the headline, but for the purpose of getting their point across to the masses and encouraging the use of as-secure-as-can-be-known software, it’s perfectly fine.

If you cover your ass in a headline, which ultimately ends as legalese, the average person will completely ignore it due to wordiness or they will become suspicious and assume the worst.

The body and attachments do not mislead at all and that should be commended.

All this pedantry is counterproductive unless you truly know and trust your audience. Proton should be for the masses, not just for the technically adept.

justinpowers··on The Uber Bubble
Yup, this selection bias is also survivorship bias.
justinpowers··on The Uber Bubble
The selection consists solely of current Uber drivers, excluding all drivers who chose to stop and take an alternative job. As well, drivers in the act of driving are less likely to admit that they do not want to be doing what they are currently doing, due to cognitive dissonance.

Additionally, there likely exists a framing bias along with a false dichotomy, if they were asked whether they’d rather Uber or take a “normal job”. There are of course plenty of alternatives that are not “normal jobs” (whatever that is exactly).

Anyways, anecdotally, I’ve had drivers who were not happy with Uber and continued only out of lack of current options or plain inertia.
