This is pretty typical aboard ship for smaller vessels on long voyages. Not so hard as it sounds: get wet, turn off; lather up, rinse off, turn off. You can do with 20-30 seconds of water and be quite clean, with some practice.
It's not satisfying though. And I can't imagine how those numbers scale if you have long hair, or use conditioner.
I lived for 3 years in a motorhome roaming around the US, taking a navy shower about every other day -- usually after an exhausting hike, run or maintenance work. It was a delight, every single time.
Yes, this bothered me too. It's impressive how much energy is required to just melt water much less bring it to temperature. It's 330 kJ/kg, which is 1250 kJ/gallon: 350 Wh. So it costs more energy to defrost one gallon of water than it does to do the rest of the 110F temperature change.
The physics term for this is the "latent heat of fusion," or the energy required to change states from liquid to solid, or vice versa.
A few years ago I saw someone calculate the energy required to melt the ice in front of a locomotive (I think) at speed; IIRC it required a (not small!) nuclear reactor's worth of energy. Not practical!

I can't deal with dates unless they include day of week. I wrote a very simple script (basically a regex) to add a letter indicating the day.
Also fun for changing website themes, extracting streams to files, augmenting games. Violentmonkey is my tool of choice for managing and live editing them.
Around early 2019 I set up a raspberry pi 3 running Raspbian. I made the /var/log partition a ramdisk. Haven't touched it since. It goes down for power outages but probably has been out for a couple minutes total over five years (aside from power outages). Most of its job is to translate analog audio to a USB speaker system. Whole house audio for about $150. Anyway, I never touch it, it just works, all the time.
There are a number of conformal coatings that can be used to keep a circuit board dry at fish tank pressures. Parylene is my favorite as it isn't too harsh on the board materials and coats even underneath the surface mount components. Doesn't usually stick to the board though so it's more of a perfectly sealed bag around the board. It's good for basically forever.
If you unplug the connectors you rip a hole in the "bag" though and the connectors will corrode. The way around that is to use expensive hermetically sealed connectors that are designed to operate underwater. Each side of those will cost a few hundred USD for boring round connectors. I have never tried to run e.g. HDMI through a bulkhead but such a connector would probably be impressively expensive.
Anyway the best thing about Parylene is you have to send your equipment out to have it applied, no do it yourself here. The spray on coatings are usually sticky, messy, and not that great overall in comparison.
>The way around that is to use expensive hermetically sealed connectors that are designed to operate underwater. Each side of those will cost a few hundred USD for boring round connectors.
In this respect, I highly recommend Cobalt series of connectors from Blue Trail Engineering: https://www.bluetrailengineering.com/professional-products - they cost "just" tens of dollars each and are very good (I used them); quite popular with ROV community.
As a small note, IP67 sealed connectors vary greatly in price, with excellent high pin count options like the Ecomate Aquarius line being in the low tens of dollars. The Deutsch/Amphenol AT automotive connectors are also very cheap yet provide a watertight seal.
I've seen some fairly generic looking many-pin connectors that are water tight. Is it just best practice to route everything through the 40+ pins and break out on the other side? Even power?

In the US so health insurance and PTO, then 401k. Hate unlimited vacation, I like owning my time off.
I'm a hardware engineer so remote work isn't very important for me. I don't really want a full lab at my home. Other things are nice but pale in comparison to having good work, good coworkers, good boss, and management I can respect.
In my company it means you can take the time off whenever you want, but we are understaffed, so if you take time off the whole project will be stopped and we won't raise money. But of course you can take vacation as much as you want.
So for the last 2 years I have had max 3 consecutive days off (and only once). I will never buy bs "unlimited PTO" again.
We are super small company, there is no management. I'm teamlead/backend developer/project manager. If I go, the whole development stops. That's how it is.
> Hate unlimited vacation, I like owning my time off.
I'm curious what you mean by "owning" your time off. I wonder if this is moreso a problem with how unlimited vacation is sometimes implemented than the idea of unlimited vacation itself.
The problem is that "unlimited vacation" is (obviously) not actually unlimited. All it really means is that you can never be quite sure how much vacation you are entitled to. It will of course depend on the company, but as I understand it, "unlimited vacation" rarely actually means that you get even as much as is legally mandated by most European countries (4-6 weeks a year).
If you leave a normal job, you'd be paid your accrued vacation leave. In "unlimited" setups, this gets murky, and normally turns into two weeks. Without a decent ledger, there becomes a stigma to actually using the time. When you "own" that time, it removes the anxiety for both parties.
I don't think there's a good way to implement it, unless it's actually unlimited, i.e. you can stay at home for two years while getting paid and it's fine.
If that's not fine, then it's not actually unlimited, and you have to guess where the limit is - so you can't really be guaranteed a certain number of days off.
Though I guess an org could still set a minimum and then call it unlimited, though in practice I expect that that minimum is basically also the maximum.
If you have a fixed PTO allocation, in most states and circumstances, you literally "own" that time. If you are fired, that balance must be paid out. In most states, if you quit, that balance must be paid out.
Like GP, I'm strongly opposed to "unlimited PTO" policies. For the few devs and workers that are helped by it, I think there are too many cases where the ambiguity and uncertainty makes people take less PTO than under a fairly generous, spelled-out policy (and there is usually no accrued balance to be paid out if you leave having taken less than the normal amount).
I won't go quite so far as to say I'd quit if my company made the transition, but it is a strong negative if that is on the benefits docket.
Yes, it can be that hot; I cuddled nude with a TLAM in the Carribbean to stay cool. I think UK boats were built for colder waters; the ventilation couldn't keep up on the deck in the shallow, warm waters.
Things are certainly not made for comfort. In cool waters my blanket wasn't wide enough to protect me from accidentally touching the weapon in my sleep. They're a great heat sink and suck the heat out of you, whether you want it or not.
While true, confidential restricted is not a US classification marking. It sounds more like the language on a clickwrap license installer, like what you would get for the radio programming software.
This sounds like not much. It would allow an eavesdropper to overhear LEO-type conversations or basic operational discussion but unlikely to be anything actual classified.
I have no idea of course. I don't even know where Arnold AFB is!
A strange document. Clearly written for public release but containing reactions of apparently sensitive clarification markings.
Moreover it contains absolutely nothing of well publicized US involvement in relevant coronavirus research with WIV.
I'm definitely curious of what DOE facilities have scientists and researchers who would have useful opinions on coronavirus. This article just reminded me more of that question.
> The program also provides innovative analysis to anticipate new and developing terrorist threats involving the use of chemical, biological, radiological, nuclear, and explosive weapons and investigate opportunities to counter them. Z Program also works to understand the state of foreign weapons of mass destruction programs; informs U.S. counterproliferation decisions, policies, and efforts; and develops supporting technology solutions to dissuade or prevent states from acquiring WMD-related technologies, materials, and expertise.
Basically their nuclear expertise plus the Cold war (and 9/11) caused them to become a central actor within the US government to look into biological, chemical, and related weapons. So they have a lot of cross discipline expertise there now.
DOE lab Sandia at least was closely involved with analysis of the anthrax powder in the letters mailed to Senators Daschle and Leahy on 10/09/2001. Note that this research didn't support the Bruce Ivins hypothesis as he didn't have the technical capacity required:
> "Not only did the Sandia researchers spot silicon, they also found tin, oxygen, and iron all within the spore. The researchers, led by Sandia chemist Joseph Michael, have presented their findings at various scientific meetings since 2008, reporting the presence of all the elements found. But because silicon had always been in the investigative limelight, tin never got much attention. Until now. The new paper puts the spotlight on tin, which the authors claim has been brushed under the carpet by FBI investigators. The FBI has "avoided public mention of the extraordinary presence of Tin," the paper says."
While it's perhaps not widely known, the DOE National Labs have the best technical capabilities for investigating anything related to nuclear, chemical, and biological weapons whether of nation-state, terrorist-group, or lone-nut origin.
It’s amazing that we’re literally talking about a major geopolitical rival’s negligence leading to the deaths of millions of people, but the right wing talking point continues to be “how can we pin this on Fauci?” Americans have been taught to hate each other more than anyone else.
Conservatives need for the lab leak theory to be correct as they were wrong about basically all other points on covid. They refused to believe in masks, lockdowns, and social distancing and paid the ultimate price at a much higher rate. [0]
i had no idea the lab leak theory was conservative. i suppose it was silly of me not to realize every opinion that a person can have has already been claimed by liberals or conservatives, such that holding that opinion means you're more liberal/less conservative, or more conservative/less liberal.
Unfortunately, American politics end up being very divisive. The right has been calling this the China virus since the beginning. Anything that can be used to show that's 'true' will result in the right's echo chamber amplifying it.
As for the left, well I am not sure there is an official position other than waiting for more data. China is definitely sus but they are always like that from a western perspective so I don't know that I weight it much.
Other than the smugness in watching the right be wrong again, I am not aware of anyone on the left that is invested in either outcome.
It's a matter of waiting for the crucial data being found. How long did it take us to pin point the source of other pandemics?
In anticipation of vindication, does the "left" not themselves then hope for the release of information which runs counter to their opponents, thus by consensus, a sword to fall on? Since without it their silly little sports team would be on the losing side. And of course in the event they're wrong they can run back to their echo chambers and self-manufacture plausible deniability. As will the right if proven wrong. In both cases either side wants to be correct — just for that little hit of "I told you so."
Of course this is all just silly bullshit. I have some inkling of hope that the truth will be made plain, but that's so implausible given current regimes and political paradigms that the only reasonable thing to do is ignore whatever is concluded, at least anytime in our lifetimes.
> i suppose it was silly of me not to realize every opinion that a person can have has already been claimed by liberals or conservatives
It's a political topic, so it naturally has positions staked out by both sides. There's not much reason to care about it one way or the other unless you have a tribal viewpoint.
I don't think your link proves your point like you think it does. It's a correlation, not causation. The question is, what other variables may impact conservatives.
One of the main factors in if you die from getting covid is age. And conservatives tend to be older.
I would love to see an age normalized version of that data. I'd bet it would be about a wash.
The only people in my circle of friends and family who died from COVID were middle age or older obese men who were ideologically opposed to taking a vaccine. I do have a number of conservative friends & family who did vaccinate, none of them got more than the sniffles.
Anecdotally, there are plenty of people with obesity or other risk factors who died despite being fully vaccinated.
Meanwhile, I had a confirmed COVID infection early on, before vaccines were available, and had nothing more than the sniffles. I then had two more confirmed infections after having three vaccine doses, and had the same sniffles.
These anecdotes, like yours, are not very useful since they only confirm what we already know: no vaccine is 100% effective, and no risk factor is a death sentence.
Huh, the vaccine uptake where I live was aberrantly low. Highly conservative. I know lots of older people, including many retired, of retirement age. I don't know anyone who has suffered a fatality from the disease - and many of those I do know who contracted would have contracted the alpha variant prior to vaccine deployment.
conservatives want the lab leak theory to be correct? They controlled the levers of power at the time and didn’t do anything about it, didn’t get redress for the death, suffering, loss, and economic harm. I would expect they’d want the waters as muddy as possible.
Wow, what a statement considering literally everything you just listed turned out to be a complete joke. I could not have made a better argument to prove a point.
As someone that believed in masks from the very beginning. The CDC and Fauci himself said masks were useless at the start of the pandemic. Stop being a pawn.
My understanding is that they said that as a path to avoid hoarding of N95 supplies which they knew were in short supply for those who most needed it at the time, medical professionals.
That doesn't aren't right, precisely because it validates conspiracy minded people.
The point is that Fauci and the CDC lied to the public about the efficacy of masks, even if they lied with "good" intentions. They simply could've explained that supplies were low and asked people not to hoard them. Instead they lied (one of many times) and acted surprised when people started distrusting them.
> That doesn't aren't right, precisely because it validates conspiracy minded people.
That’s putting it far too lightly. It proved a “conspiracy” 100% true. I had masks early in the pandemic only because a “nutty” colleague said “they’re going to try to take the masks from us” and he brought me a box.
That's the explanation they came up with for why they were lying, but these people are self-admitted liars so why would you believe their lies any further?
If you are in charge of government and worried about mask availability, the right thing to do is pass laws seizing mask supplies. This is easy because they were almost all being imported from China anyway.
The worst possible thing to do would be to assert with 100% confidence that for scientific reasons masks don't work to the entire population including healthcare workers, and then later invert your position over night. Anyone who thinks this is a reasonable way to manage material logistics is clearly far too stupid to be in charge of anything, let alone critical government functions.
Lockdowns were a failure, hence why millions of children were irreparably damaged by them socially and academically.
The legacy of lockdown proponents is plummeting test scores and massive IQ drops, because children were merely collateral damage to their hypochondria. [1] [2]
