evanlivingston··on One Year Since Germany's Nuclear Exit: Renewables Expand, Fossil Fuels Reduced
Whenever power in Germany comes up, I have a hard time interpreting anything because of the reaction the HN crowd has against the Germany's resistance to Nuclear.

But from what I can tell, they're doing a pretty good job reducing their usage of fossil fuel? Can someone clarify.

Yes, power is more expensive in Germany. Yes they have periods where they don't produce all the power they consume, yes the import nuclear power. But for their goals of reducing fossil fuel consumption and not building nuclear power plants they seem to be doing well?

This is a great point but has me realizing I don't know how to square this with the idea that quite a few people are making enormous profits from unprofitable businesses.

It feels like there should be a way to tax these startups that exist as vehicles for cash grabs, but are not profitable.

evanlivingston··on Ask HN: Now That Phillips Is Enshittified, How Can I Run My Phillips Hue Lights?
There are a handful of solutions to the problem of the lights being on while in bed, but wanting them to be off. One way is to turn off the lights before entering the bed. Another way is to get out of the bed and turn off the lights and then return to the bed.

Another popular solution is to place a lamp near the bed, such that the light controlled by the wall switch can be turned off before entering the bed and the lamp nearer the bed can be turned off while in bed.

evanlivingston··on USGS estimates at least 45% of U.S. tap water contain forever chemicals
I assume this is true for 1) filters that are NSF certified and 2) wish to not display a prop 65 warning.

A majority of the water filters purchased on Amazon are not NSF certified and ship with a prop 65 warning. In fact, it's difficult to purchase water filter components that do not have a prop 65 warning.

APEC doesn't appear to even be certified by NSF which is rather disconcerting.

NSF at least certifies their claim.

That's a surprisingly small volume of water though. I also don't love how private they are about what the filter media is.

Boiling can _increase_ dichloroacetic acid. If it were run through an RO first, then this is likely less of an issue.

Yah, this is totally a thing.

Charcoal filters have a relatively short lifespan.

The testing is probably already done for you!

FYI: charcoal filters can introduce arsenic and also appear to increase the bacteria in the filtered water.

Also, all those RO systems run the water through an enormous amount of plastic, and store the filtered water in a rubber bladder.

When looking into this previously my decision was to avoid introducing yet another potential source of contamination.

evanlivingston··on Geoffrey Hinton leaves Google and warns of danger ahead
er,

It was not asked to provide an unethical response, it was asked to provide a response given no ethical boundaries — those are two different things.

Further, when we see the words "ethical" or "moral" we should remember these are flexible human constructs. They're open to interpretation and indeed most of us have differing answers. An "AI" with good moral reasoning skills might still find it's way to some spooky results!

My point here is, this is still an interesting exercise because it's demonstrates how quickly an LLM can move into extreme territory.

evanlivingston··on Geoffrey Hinton leaves Google and warns of danger ahead
This comment captures exactly what I find concerning around the common line of thinking about AI.

How is a value judgement or moral that _I_ hold different than the list output by ChatGPT here?

evanlivingston··on New 3D Printable Search Engine
This is, in practice, the utility of the widespread use of CAD. Many manufacturers of parts distribute CAD models of those parts.

For example, McMaster-Carr have CAD models (in various formats) for nearly every single part in their catalog.

A designer/engineer can import those parts and then either create drawings referenced off of those parts, or mate/join those part using reference geometry. That is to say, the API is the geometry, and the CAD software provides good tools for interacting wit that API.

evanlivingston··on Ask HN: Supplements and vitamins that help with ADHD
Er, when I went looking into the research I only found inconclusive results for it's benefits. I took it for a long time to help with nicotine cravings and ADHD and never noticed a semblance of a beneficial effect.

There's also an increasing concern that it's actually a carcinogen.

evanlivingston··on Circadian lighting with Home Assistant: Like f.lux, but for your house
I use incandescent and halogen everywhere and don't have a problem with color temperature. Also, the CRI of my bulbs is incredible.

My house has maybe 20 light bulbs in it, most of them under 75 watts, except for a couple of strategic halogen fixtures.

Sometimes I think about getting LED smart lighting, but then I think about how many iterations of setups I would have to go through it get everything dialed in, all the e-waste I would be contributing to, all the plastic, all the security vulnerabilities, all the software updates, all the glitches, all the flicker from cheap PWD circuitry and I decide to stick with simple glass and red hot metal.

evanlivingston··on Ask HN: What interesting problems are you working on?
I mean, at what point do stop and ask yourself if the thing you're making is going to cause bad things to happen? Do we only consider that when the thing is really obviously a weapon and ignore all the other creations?
evanlivingston··on Ask HN: What interesting problems are you working on?
I fail to see how considering the impacts of a tool before building a tool is putting the cart before the horse. How is that not a necessary step in building a thing?
evanlivingston··on Ask HN: Pricing for a Jet Lag App?
My wife flies internationally a number of times a year, and I'm sometimes with her. We've been using timeshifter for a couple of years. It's current pricing of 24.99 a year is in an awkward spot where if we _know_ we're only flying internationally _once_ that year, it's expensive, but if there are three trips planned, it seems cheap.

I would love to just pay $5 a (round) trip. The price per trip model becomes funky if the user needs to modify their flights at some point.

The first time we used Timeshifter it worked so well we knew we needed to always use it.

My one gripe with Timeshifter is that is assumes I can keep to it's schedule perfectly. What happens if I couldn't sleep on one of my flights, or had to wake up earlier to catch a train to the airport?

evanlivingston··on Coinbase lays off around 1,100 employees
Yes?

Whether you're receiving the value of the asset or not, you're locking up the value of the asset and preventing a larger group of people from benefiting from the value of the asset, which is sort of the point of a wealth tax.

I assumed it used some technology that made it look less like a digital display and more like a analog object. Also, I (stupidly) assumed that it was similar to an e-ink display I that it could display images when it was powered off.
