Studies have all come out clean on pacemakers and mmWave. No detectable interference in the hardware or on an EKG while in a mmWave scanner.
I could imagine other conditions potentially but pacemakers have been ruled a non issue for mmWave by academic studies (albeit I can understand still exercising caution despite that).
Tbh I'm not sure but they've done accelerated dosage testing to simulate long term use by repeatedly exposing people to use of the machine over a more frequent period of time.
But mmWave really just is not dangerous. Current generation 5G cellular and WiFi standards are mmWave and they are just as harmless.
Molecular damage just starts showing up with THF/terahertz emissions band but mmWave is in the EHF and is has more than 10x the wavelength of THF (i.e. it is far wider/more gentle than THF). In a very real sense mmWave can't even interact with most of the molecules in your body.
mmWave can interact with the water in your body but at the levels it's being used it's only really useful for seeing the water. You'd needs orders of magnitude more powerful emissions than what these scanners use to actually cause damage at that frequency.
i.e. It's the difference between using the flashlight on your phone to see in the dark and using the concentrated light from solar-thermal heliostats to boil water or heat molten salt. No matter how hard you try, your flashlight is never gonna boil water.
Ridiculous nonsense. Boycott Fedex because of a $2.3M delivery contract with ICE? Cancel Spectrum internet because there is an ICE field office in Texas that uses them? Cancel Comcast because they provide cable TV? Unsubscribe from Netflix because...no reason?
No wonder it is organized by a professor of marketing who has been building a personal brand of hating the tech companies for a decade.
You can measure my productivity by how slouched I am.
Sitting up straight at my desk, chair locked, perfect posture? I’m doing nothing, maybe looking through System Preferences to change the system highlight color.
Sliding down in my chair like jelly, with my shoulders where my butt should be and my head resting on the lumbar support? I’m building the next iPhone and it’ll be done by 2 AM.
Funny, I’m the same. I also like taking walks to think but I’ve found that I must have my head pointing almost directly down (I.e. looking at my feet). It’s also how I stand thinking in the shower, with the warm water hitting my angled neck. Maybe something beneficial about that position of the neck, or maybe just habit!
I will also have conversations in my head during my walk, I’ve done this my whole life and I’m not sure to this day whether my lips move during these or not. In any case, I must get some funny looks with head bolted to the ground mumbling to myself…
As for the software. I would not want a camera on 24/7 (on any device, a compromise being my doorbell, which isn't cloud connected). It'd defeat the small LED which informs you it is on (since it is always-on), and if the machine is compromised this is a method to receive personal data.
Actually, I'd prefer a hardware killswitch on things like camera and microphone.
Alas, I'm not alone in meditating and thinking while taking a shower.
It's one of the moments of my day when I recollect what happened, what I need to do, and what not to do.
The problem is that I can get quite lost during this phase, and hot water isn't cheap, so my SO is always threatening to put a big timer in the bathroom.
My pet hypothesis about why shower is often praised to be such a mindful place is that it has not so much to do with water and more to do with the fact that for many people life alternates between 1) constant social interaction and interruptions from other people and 2) bathroom time.
How many people these days have a dedicated home office, off limits to anyone else? How many partners sleep in different rooms?
Sure, perhaps the sensory experience plays some role, but if your bathroom is reliably the most interruption-free place for you, naturally you’d form a habit of catching up on all the “slow thinking”, most negatively impacted by interruptions, during shower.
I’ve seen people with interruption-free solo hobbies (be that hiking in the woods, motorcycling, rock climbing, etc.) describing similarly mindful experiences, but unlike those shower is the lowest common denominator and perhaps one that happens most routinely.
In my case, though walks help declutter my mind somewhat, for deeper thoughts, I have to write it down sitting or laying in the bed in the worst of positions. Thinking too deeply while walking only leaves me anxious in the end as I tend to get sidetracked a lot in conversation and always have to restart the conversation over and over again.
I tried doing the same. Sometimes it made my understanding of things much clearer. However most fimes, I found it worked best when I had a clear idea on paper, either to validate the idea or when I needed to an opinion. Otherwise, ChatGPT in my case, built upon my idea that I hadn't thought through well and confuse the shit out of me.
This is how things get built for me as well. I have a standing desk and like using it occasionally but if you see me standing at it you can bet I'm doing something typical like emails or chat and not thinking deeply.
If you delete social media, and leave your phone away from your person all day with notifications turned off, you can have these moments all the time it turns out.
Considering how much more productive these moments are for me than the bullshit I used to do on my phone and social media, it was an easy decision to make.
Oh, lol, now I get your question. Yea, it turns out the silence and lack of distractions are what produce "shower thoughts", more so than the act of showering itself.
Doing any relatively rote act like washing dishes, walking places, etc can also give rise to them. Not having a device in your hand to constantly steal your attention really helps though.
Showers are generally considered to be relaxing separately from the “shower thoughts” phenomenon.
Couldn’t the relaxation be a factor in generating shower thoughts?
I suspect that essentially none of our non-ancestors were predated in a hot spring, unlike walking etc, so there may be an environmental cue driven induced relaxation that doesn’t exist for many other activities.
Yea, you relax, and then your brain produces random thoughts about things.
I suspect it's just about getting the space to relax, which is why I frequently have thoughts when staring at the wall, or taking a walk, or washing dishes, or doing any other myriad activities which are relatively easy on brain processing.
I find pacing to be helpful. As long as there’s not a lot of poles to walk into accidentally. So while outside walks can be more focused you do get the odd head bang.
I never understood this. Is this why the cubicles are always full in the office? WTF I go in there take a dump and leave while the people on each side are just silent the whole time. I can think of much better places to think.
This is interesting, because in many ways I’m almost the exact opposite.
If I’m slouched in my chair, then I’m either completely disengaged or doing something mundane like dealing with email. If I’m upright or sat forward then I’m engaged and executing, but maybe not thinking deeply - I’m doing something I’ve already thought about and decided on. And if I’m on my feet and moving around, often doing some mundane chore like emptying the dishwasher, then I’m likely thinking.
It’s actually a really good illustration of why one size fits all solutions when it comes to work environment and conditions are often so unsatisfactory.
Exactly what I came here to say. I've been programming for 40 years, 35 professionally, and I didn't find my ergonomic, no-pain, no-RSI happy place until I stopped following advice to sit up straight. I set my chair with just enough resistance, set the head rest where it puts my eyeline directly on my monitors, which are set considerably higher than average and about a metre from my head. I can work for hours like this now, with no pain.
I could never use an app like this. Maybe I should write one that blurs the screen when I don't slouch.
it will be interesting to see as these tools emerge to what extent the undercontrolled behavior is a piece of a larger cycle of attention and context mgmt, or if all of that time can be nudged back into the zone
In a previous tech bubble I figured out that the Aeron chairs were great - if you were using good posture. Slouch at all and they'd hurt you. The humanscale chair was the one that was actually good for feet-on-desk, keyboard-in-lap, staring out the window while rotating data structures in my head...
This is a great example of how patronizing policies developed by intellectual authorities backfire in the real world.
The premise is, the general population is too stupid to do the right thing themselves and need to be reminded of the drought by being inconvenienced by completely ineffective performative policies.
All this actually does in practice is diminish trust in authorities to make good decisions. If the drought policies are bogus, which other ones are too? Fuel economy standards? Air quality? OSHA?
Instead of this nonsense - just allow the market to set the price of water based on what’s available.
Of course, the answer there is usually “Oh but there are special interests that need to be able to consume as much water as they want without paying more for it, even in a drought!” And thus as usual the problem is not the personal conduct of individual citizens but corrupt and spineless politicians who are not actually interested in solving any problems.
> just allow the market to set the price of water based on what’s available.
There is a base amount of water that everybody uses as a basic necessity, and then there is water used on top of that for water hungry lawns that is not. If all you can do is set a flat, non-progressive, water usage rate, the wealthy people who use a disproportionate amount of water will not change their behavior.
The same anti-tax Republicans who gave California the disastrous Proposition 13 also gave us Proposition 218. The people in charge of water policy know what they're doing better than you do, but their hands are tied by the voters. https://www.ppic.org/blog/prop-218s-ongoing-impacts-on-calif...
I'm always surprised when people think they know something better than the professionals and just complain about it to other non-professionals. Just explain your idea to the professionals. If it's actually reasonable, they will change what they do. I have done this successfully with local governments many times.
> just allow the market to set the price of water based on what’s available.
I'm 100% with you overall on the basic thrust of your comment, however I can't help but think that if we were adjusting water prices, somehow they'd go up by 60% in the dry years and go down 10% in the wet years.
Maybe that's just because here in California we pay 2x-3x what anyone else in the US pays for electricity, and 50% more than most people pay for gas.
I don't know why California's electricity costs so much, but the gas prices are high due to regulation distorting the market. California has special California gas produced only at in-state refineries. It's for a good cause--California's gas, "CARB gas" is cleaner. But the gas market in California is segregated from the wider US market
No! What a disaster. Enforce the costs of externalities as close to the source as possible. If electricity costs more money charge more money for electricity. Don’t add some “regulation” to force end users to pay more based on your estimate of how much more you think electricity should cost.
I said force the cost to the surface. Not set a fixed rate of return: I want the accounting on the build and supply cost at large, as well as the KW charges to be accounted for.
Not obvious to me that this is worse or as user-hostile as many seem to presume.
Previously the blue background made the ad result look more highlighted and more prominent.
Now it is just like the other results - not special or better.
Yes, the HN audience knows the visual convention indicates that the blue background represents an ad. Does your everyday user know that or do they assume the blue results are better?
This is much less interesting than the headline suggests. 1.5 times background levels, of a single very long-lived isotope, is not much of an increase.
This doesn’t indicate that there has been a recent undisclosed accident or other newsworthy event as you might be imagining.
You are right that due to its very long life we cannot know when it has been produced, perhaps decades ago.
However the fact that only iodine was detected is to be expected, as the other radioactive products of nuclear fission are much less likely to form chemical compounds that are soluble in sea water, so they could be somewhere on the sea bottom.
The part of the article that caught me was that European Companies used to just drain nuclear waste (not sure what type), into the rivers in China and they would eventually flow into the sea
Russia's former Lake Karachay was an impressively polluted location, the early Soviet reactors were cooled with an open loop where highly contaminated water was discharged directly into the lake. The lake eventually became thoroughly sedimented with nuclear waste, and when levels dropped radioactive dust would be blown about the region. Apparently just half an hour on its shore would have been enough to doom you from the amount of radiation exposure.
They eventually filled the lake in, I can only say hats off to the poor buggers who had to do that. I think it's safe to say they had the world's worst job at the time.
