bevan··on Vitamin D and Omega-3 have a larger effect on depression than antidepressants
A useful way to look at the effects of vitamin d and omega-3s: supplementation isn't really a hack, it's more that their removal is a handicapping of our "normal" state. Our evolutionary conditions would have been more rich in both of those things. Also see light exposure during the day, proximity to green space, etc.
bevan··on Show HN: Claude Code Usage Monitor – real-time tracker to dodge usage cut-offs
Something like this would be great for Cursor, I never know how many credits I’m up to for the month or how much my Max calls are costing.
bevan··on What happens when clergy take psilocybin
I think we're talking past each other (or maybe mysticism and Hegel don't mix!). These mystical experiences touch at something on a different level than reason, a little closer to base metal. I mean that no reason or representation can capture that most fundamental reality of being, the fundamental experiential truth. Reason can try to explain it, and reason can help guide some people to the experience of it (jnana yoga, getting a satori from reading Eckhart), but it cannot itself know it. Meditation, psychedelics, dance, or whatever else are the typical pathways to it. All reason, all facts, are subordinate to it and less true than it. Or can being be contained by reason?
bevan··on What happens when clergy take psilocybin
You don’t need to take drugs to know things, but reason only covers a portion of what can be known. Reason doesn’t really help one understand the nature of experience itself. That’s a whole different kind of meta-factual knowing, an infinite subject that some people approach through meditation (and psychedelics too).
bevan··on A 6-Hour Time-Stretched Version of Brian Eno's Music for Airports
Gary Hustwit (Helvetica, Objectified) just made a worthwhile documentary about Eno: https://www.hustwit.com/eno

It's only streaming right now and each streamed version is unique, riffing off of Eno's "generative" music.

bevan··on Show HN: Knowledge graph of restaurants and chefs, built using LLMs
This was inspiring, what a cool idea. Just curious—-for 4o mini isn’t there a json mode that reliably produces structured output? Was that what you were referring to / ended up using?
bevan··on How to improve your WFH lighting to reduce eye strain
Strategically increasing the amount of light I'm exposed to was a game changer.

Turns out we're bad at gauging how much light is in our environment. Few would suspect that the amount of lux we're exposed to indoors is often far less than 1% of the lux outside. A typical corporate office has under 500 lux, vs 50k+ midday-if you're at home and haven't put much thought into the lighting situation, the lux could be in the low double digits. You can get a free app "Lux meter" to measure yours now.

We evolved to be outside a lot, and light regulates aspects of our biology. We probably shouldn't stay two orders of magnitude beneath the factory recommended exposure levels for months at a time. Hence clinical or sub-clinical SAD,sleep and mood disturbances etc [see references].

One solution is high wattage LEDs: https://www.benkuhn.net/lux/

I've had several ~250w LEDs over the years (these are huge and actually draw 250w, they aren't 250w equivalent). 250w might be overkill, and 80w is fine for me and a lot more practical. If you get one , be warned that depending on the wattage you'll probably have to build your own stand for it as most fixtures aren't rated for that high wattage.

Related to light amount is of course light timing. This may be more important than getting a steadily high amount of lux during the day. Get lots of light in the morning, and not a lot at night (just low intensity bulbs, maybe just red ones, starting 1-2h after sunset is nice). That helped my sleep a ton. Check out Huberman LAb, he talks about light amount and timing ad nauseam.

Not using those “bad practices” of third party analytics can be an existential threat to small businesses, unfortunately.
bevan··on Ugandan runner due to arrive in London after 516 days, 7,700 miles on the road
Yes, that's explored in the sequel. He lives on in Urique, Mexico where his likeness is plastered everywhere and is the namesake for the big annual race in that town.
bevan··on Ugandan runner due to arrive in London after 516 days, 7,700 miles on the road
It is insane in today's world! But big mileage (barefoot, no less) is something we evolved for. Check out the great book Born to Run by Chris Macdougal which explores that concept.
bevan··on Ask HN: SWEs how do you future-proof your career in light of LLMs?
Commenting on the useful-not-useful split here.

Rather than discuss the current “quality of code produced” it seems more useful to talk about what level of abstraction it’s competent at (line, function, feature), and whether there are any ceilings there. Of course the effective level of abstraction depends on the domain but you get the idea, it can generate good code at some level if promoted sufficiently well.

bevan··on Show HN: We Built "Wikipedia Link Previews" for YouTube Videos
Hey Komod, good callouts. It could be improved, I'll clarify these points on the site.

- We cannot see your YouTube activity => ie what you watch, search for, like, subscribe to. This is clearly explained beneath the TLDR section. What we CAN see is also explained.

- Your chats are only visible to you => as in, they aren't public. That could be clarified. We do state before that that we save your chats.

- We don't mention them by name, but the second line of the TLDR is "• We track Extension usage statistics to improve the product." Have added an explanation for each of them.

Appreciate your help with this. What did you think otherwise?

bevan··on Show HN: We Built "Wikipedia Link Previews" for YouTube Videos
Appreciate the comment! Let me know if you have any feedback

bevan··on Show HN: I am Building a Producthunt alternative
Just tried posting my site (which I was gonna launch on HN today anyway).

https://strawberry.army ("Hover Youtube Thumbnails for Instant Summaries")

...but got a 500 error. No other clues in the console.

Good luck with this!

bevan··on Show HN: I'm building a Product Hunt alternative, it's 4 days old
Congrats on the launch! Are you addressing any specific issues with product hunt? Would be nice to see those on the homepage, as it’s not clear from the website copy what the advantage is.
bevan··on Coffee helped the Union in the Civil War
There’s a short and fun book called Blitzed about “PED” use in WWII. Covering German pharmaceutical industry’s monopoly over certain stimulants, Hitler’s unlikely doctor who shot him up with everything under the sun, and the ultimate consequences for everyone involved (addiction, exhaustion, insanity).
bevan··on Dehydration associated with poorer performance on attention tasks among adults
There’s a Huberman Lab for that: https://youtu.be/at37Y8rKDlA

He cites more evidence showing that even moderate dehydration (when you aren’t thirsty) leads to lower performance (mental and physical). And talks about overhydration and hyponatremia. IIRC also discusses how hydrating at different times of day affects you, turns out your kidneys dump water quickly if you drink too late. So hydrate before six.

bevan··on Clicks – Physical keyboard for iPhone
For the creator of this product (and to any other creators launching soon): don't listen to the keyboard jockeys saying it will fail. We (commenters here) are essentially NPCs in your world. We're not your narrow target market, just some gawkers addicted to typing "news.yc..." into our browsers, maybe with nothing better to do. And although we sound confident, we really don't know if it'll fail, or take off, or pivot to a successful product. Good luck--and major props on the launch, the landing page looks great!

ps. It will succeed.

bevan··on How big is YouTube?
I noticed that too. Seems very unlikely that 1,000,000 subscribers represents the 98th percentile and not the 99.999th.
bevan··on The Greening of Milan: Porta Nuova and Vertical Forest
This is awesome. Living around nature is not just pretty, but healthy for us and good for our focus / productivity / mood / fitness / recovery / general well-being.

For a look into the benefits of living near green space (ie nature contact):

Indoor plants also have salutary and performance effects.

bevan··on Show HN: I built a website to buy and sell used clothes in Indonesia
Great site! Had a brief look and the clothes look great.

Looks like CC isn't accepted, but bank transfer is. Curious why that is?

bevan··on Loneliness is stronger when not alone
Damn, I'm sorry to hear that. I relate to this because I've dealt with depression too, which I also medicated in various ways.

Other than quitting the two aforementioned drugs, what helped a lot for me was living in a more evolutionarily consistent way. Especially around nutrition, sunlight, and sleep. I made this the focus of my life for about a year because the alternative was, well, you know about that.

Good luck.

bevan··on Loneliness is stronger when not alone
Since quitting caffeine and alcohol, I rarely get lonely. In fact, quitting those drugs seems to have helped reduce the time I spend in any negative emotion. I still have acute bouts of [whatever negative emotion here], but I rarely get mired in them. This seems to have less to do with any change in my living situation since the switch (I often hermit away, as I did before) and more to do with being in a more resourceful state more often (which neither drug helped with).

I suspect that alcohol and caffeine-induced negative emotion is widespread. Even a glass or two of alcohol can affect your sleep, and less REM sleep means less emotional regulation. I know basically everyone's on caffeine, but ingesting that can accentuate the peaks and valleys of one's emotional experience. The alcohol and caffeine-induced troughs may be sub-clinical, but they're probably real for a lot of people.

bevan··on Ask HN: Best ways to volunteer?
Earning to give (to the top charities) is likely orders of magnitude more effective than most other volunteering options.

Research effective altruism and see GiveWell’s most effective charities list (updated a week ago).
