I've designed and am trying to mass produce fans for cr-box style air purifiers, which are far far quieter for greater airflow than the usual box fans. About 10% more flow for 1/220 the noise energy (24 db). Www.bigquietfan.com

Someone robs you every day for a whole year and all you settle for is a refund?

No, you need to get those people out of power. Stop hiding from the real work.

Uh so you are going to just rev up the immune system permanently? Clearly that's likely to have serious downsides. An overactive immune system is exactly the main problem with many long COVID situations. Iirc. The system will also get exhausted etc?

Man the big quiet fan is pretty much done now but I'm waiting on other people mostly. Just gotta get it produced now. Everything is so slow.

Why don't we make a meta tool to integrate all such wisdom so we can have something we can just ask to do X and it actually does it?

The thing is, when will someone make a meta tool that harnesses all these tools using wisdom like this? When they do, we will be back to that prompt except it will do a better job on larger tasks with smaller prompts.

So if we suppose 38.3 thousands people, that's a million dollars per person? Yes. Have we all forgotten how to do math???

I'm pretty sure you could get away with a filter on the intake. I would expect whatever goes in comes out. The resistance to airflow at the intake is not a big deal, the pump is very powerful and will not notice. I see no reason it would fuck up the machine unless they did a really trash design

They claimed to be from pratt and whitney, but were using a clearly bs Gmail address. They cannot spoof a fake address very well. They can't have the right domain name to make that part convincing. We need some way to stem the tide of fraud.

Someone tried to scam me just yesterday. It looked like they had a bot of some kind reading websites and sending emails to lure you into something. I blocked them immediately. Their email addy was shit. Thing is the email addy they cannot have for cheap. Tokens they can.

What's your input and output solution? I.e. keyboard and mouse plus head mounted display, I guess. I think there is a ton of potential to improve these. It's nuts to be chained to a certain bodily position so much of the day.

I would prefer to roll it together with other reforms that improve things across the board, including taxation. This may involve raising taxes on some regular people in some ways, but usually reducing them and taxing rich people more. I don't think it's best to frame the issue as us needing to pay

That's more like market research than engineering though. Also again they literally do not know. My personal solution is to use rational economics as a guide, however you could easily starve like that. You cannot predict behavior of humans that well.

There was open source ecology, and look what happened to it. This explains why we do not have them now.

I'm with you. Collapsing things to blame on the individual is exactly what the ruling class wants. There is an excellent article in the palestine issue of Science for the people magazine discussing this. However we all do have a bit of lattitude, it sounds like you do use that. It does add up.

To be fair, people generally do not know what they want. Even if you ask them, they will not tell you what they really want. If you make what they want they will squirm out and not buy it most of the time.

Someone should tell the boss that, though. The respectable kind of engineering is like that. Unfortunately we are usually coerced into being a cog in a giant scheme to extract money from people. And to survielle and control them. Or even kill.

Technological progress! I no longer like caffeine though. Looking back, I've consumed a great deal and it's not clear it gave net benefit. The downsides are quite harsh and generally underappreciated :(.

According to Wired, ICE has leased space in Southfield, Mi. The feds are being all hush hush about it. Maybe we should throw a welcome party for them, complete with whistles.

There is a book entitled happiness:a guide to life's most important skill. Sounds like bs but the guy's actually a former biologist. It discusses similar phenomena and offers some good ideas on how to do better, with modern psychology/neurology knowledge and Buddhist wisdom.

It also improves reliability. If things can be repaired independently, it removes the incentive to use planned obsolescence, so things will be better designed from the get go. Repairability also tends to go hand in hand with compatibility.

What a profoundly foolish effort to try to hide from the whole world in silly boxes. You cannot escape drought, famine, war, hurricanes, fascism, by hiding in a box.

As someone who designs energy recovery ventilators and air purifiers, this is absurd. You can't hide from the whole world in your silly box. The fossil fuel taps must be turned off. Nothing else will work. It's foolish to put your chips in that basket.

It's very much this. It's a crazy regulatory thing, but i think it's not so much about the bike lanes as the lack of licensing that other vehicles require, and other rules
Basically the government idiocy is causing this, however it's not a huge deal. People just ignore the pedals.

The only reason they are pedal assisted is regulatory burden. The cyclist contributes an average of 180 watts or so. That's nearly negligible. They can help during acceleration but in general they don't bother.

It is not a barrier. The barrier is the insanity to want something that is in fact different to be the same. People want everything to stay the same but somehow be better. There is no need for that. It only has to be better.

To be clear, if you had the potential to actually completely solve the problem with some drug then sure. But the problem is that's inherently never going to happen. Best case scenario you get some weak excuse for a solution, whereas addressing the root issue can completely solve the issue

No. Again you are messed up by the logic of capitalism. Offer them a superior job which does not fuck up their health. It's a rare case anyone would choose to fuck up their health for some shitty job when there is another perfectly l perfectly good one on the table.
