> How does panel efficiency go into this?

It doesn’t but a measure of output from solar panels ignores the storage efficiency which is what we care about here.

> 200w/kg is system efficiency.

You listed that as the panels in your post.

First actual array output falls over time. Whatever it would be new is irrelevant you scale for how long it’s in use. Panels on the moon need to be mounted at an appropriate angle for maximum efficiency, cooling, they need wires to move electric from the panel to your power conversion, electronics to handle that power etc. You also get losses from lunar dust, etc. Simply saying all that doubles weight is a reasonable ballpark.

Don’t forget the moon is dealing with days of full sun panels need to maintain low temperatures for efficiency and you can’t just dump all that heat into the moon.

> I don’t get it

A 50kg array consisting of 25kg of solar panels, at 30% efficiency produces: 25 different 0.2kw panels for 30 percent of the time over 28 days times 24 hours = 25 * 0.200kw * 0.30 * 28 * 24h = 1008 kWh or 1.008 MWh.

Edit: 1.4kW * 28 days * 24h/day = 940 kWh or 0.94 MWh.

> A round-trip from a fuel-cell system will be at ~40%.

I have yet to read about an actual working system over 30% water to hydrogen to water. Do you have any citations or is this assuming some unknown breakthrough?
> What keeps them from changing or trying out new ways of designing/building? Is it entrenched interests that resist any changes?

If someone had been honest and told Congress "Oh, the F-35 will cost $1 trillon dollars" they would never have approved it. The military does this so that they can claim something will be cheap. Then over the next 5 to 10 years they increase the cost astronomically, step by step, because Congress will look bad canceling the program and getting nothing for all the billions they spent so far.

There's no one resisting the change. If I gave you unlimited money, but all you had to do is take it $100 at a time, you'd do it too. The problem is that Congress refuses to keep the DoD accountable.
It’s going to be interesting to see if this gets used elsewhere. Something tells me we’ll probably see a lot more of this happening in the future.
Reference [1] is applicable to how our body handles an immune response to the viral infection in general: i.e. whether naturally acquired, or through controlled vaccination. Natural infections were, naturally focused upon, in order to understand the baseline dynamics of viral infection.

Reference [2] is...it says just as much about the efficacy of vaccination as the efficacy of natural immunity:

> The cumulative
incidence of SARS-CoV-2 infection remained almost zero among previously infected unvaccinated
subjects, previously infected subjects who were vaccinated, and previously uninfected subjects who were vaccinated, compared with a steady increase in cumulative incidence among previously uninfected
subjects who remained unvaccinated.

Read reference [3] to understand why natural immunity doesn't cut it. Note that widespread natural immunity causes the same positive selection pressure as widespread vaccine deployment, and:

> Finally, our work suggests that immune evasion requiring one to two mutations occurs within months, raising the prospect that this phenomenon will further shorten the duration of natural immunity...

The paper goes on to provide (under Discussion) a series of strategies for developing a vaccination system that takes into account modelled viral evolution. Can't come up with strategies like that for natural immunity, apart from: "periodically re-infect individual"...which is exactly what vaccines do, in a controlled manner.

Reference [4] and [5] are research tabulating mutations the virus is undergoing to counter both natural acquired and vaccine-mediated immune responses. It is not an indictment against vaccines, but just like paper [3], provide strategies on how to update vaccines. That updates will be required is not a surprise to anyone. Viral evolution has long been known of, and no one expected the emergency COVID-19 vaccines to be effective until the end of time.

Reference [6]...did you read it? It's about vaccines which protect the host(keep them alive), but still keep them infectious (capable of transmission). None of the COVID-19 vaccines do that...
I don't know if they still do after the buyout, but New Belgium Breweries had a bioreactor that used spent wort to produce methane to help fire the boilers. Then the doubly-spent wort went into compost for the landscaping.

I'm thinking that the shorter supply chain there probably works better, but then again you need multiple examples to get most people to actually start solving problems so kudos to GF for at least trying.
So are they only scanning things you specifically upload to iCloud, aka if you disable iCloud and photo syncing you are fine.

Or does that include ancillary data like images in iMessage chats (even if you have iCloud data basically shut off)

I read the scans were done on device but prior to upload. Just unclear what that really means to me.
I don’t believe democratized prostitution is a negative thing. If anything countries like the US would have far fewer criminals and desperate incels if we just legalized it.
> Master's thesis

I don't doubt this at all, and I have no doubt that GPT-3 with a bit of human editing can spit out something better than the lower third of masters students at corn row colleges.

Masters degrees are cash cows, which is why no one in unregulated industries cares about them. People in regulated/unionized industries also don't actually care; even educators, who at least nominally see intrinsic value in education, go to borderline diploma mills to get that union-mandated raise at minimal effort.

It was not all automated, there was a fair bit of manual intervention needed. I understand your concerns and they are valid and this is why I preface my statement with "anecdotal evidence". What I write is most certainly not the entire story and a fair bit of detail is left out.

This article doesn’t capture the flavour of what happened here.

Here is the letter sent to staff.

You received this email because my big data team analyzed your activities in Jira, Confluence, Gmail, chats, documents, dashboards and tagged you as unengaged and unproductive employees. In other words, you were not always present at the workplace when you worked remotely.

Many of you might be shocked, but I truly believe that Xsolla is not for you. Nadia and her care team partnered with seven leading HR agencies, as we will help you find a good place, where you will earn more and work even less. Sasha will help you get a recommendation, including the one from myself. And Natalia will read you your rights.

Once again, thank you for your contribution. If you want to stay in contact with me, please write me a long letter about all your observations, injustice, and gratitude.
The underlying factors that drive and produce the outcomes of these two systems makes me think your comparison is a false equivalence.

I guess there's an element of randomness to everything and any company could go under overnight, but in general I think you can rely on hindsight in terms of performance. The higher you get up the ladder and aggregate, the more stable I feel that is.

If you're just comparing the methodology of extrapolating expected returns from hindsight I would agree with you.

I guess what I'm saying is using hindsight to pick a direction seems logical. And doing it from a broad perspective seems more stable (using hindsight to predict if a company will go up vs using hindsight to estimate if a sector ETF will go up). However, I agree that I don't think you can estimate how much it will go in that direction.

There's probably a fallacy in my logic there somewhere. But the results in the real world are good. If those returns are all just luck, well at least I had fun and made some money.

That was a theory around why certain countries have fared relatively well, places like Cambodia and Vietnam.

Their populations could have been exposed to similar viruses and would have had some built in immunity.
> Unfortunately fixed price contracts don't work for new cutting edge defense systems. No major defense contractor would ever take on that level of risk so there would be zero bids. Fixed price contracts only become practical after the R&D work is complete.

That's demonstrably false.

All civil aviation works by companies shouldering the weight of development then selling their wares. Heck, the whole non-military economy works this way. And even a good chunk of the military economy where they buy modified civilian goods.

There's nothing special about weapons systems. There's a market. You do market research. You know you can sell X units for Y cost. You build the thing. You sell it.

There's only something special about the DoD. They're not being held accountable and they don't give a damn about the long-term financial welfare of the country.
I just looked it up. Where I'm staying the tests are 57e, you do it yourself, and get a result within 20mins which is valid for 24h. That definitely is a high cost.

Amazing user interface. Seriously inspiring stuff.

He was a socialist and a leftist but not a communist. Not all leftists or socialists are communists, not all communists are Leninists or Stalinists.

>So were the NAZIs right wing or left wing?

Right-wing. The only reason anyone claims otherwise is that "socialist" is in their name, but National Socialism isn't socialism any more than North Korea is a Democratic Republic, and the proof is otherwise in the pudding as far as Nazi politics and ideals are concerned.

Peter kingsley talks about this in both reality and a story that will pierce where you dive deep into the hidden connection between Pythagoreans and mystical traditions leading back to the mountains of Tibet.

The teachings of Falan Dafa also discusses this claiming that the earth and human civilizations has gone through cycles of destruction and renewal with the last period occuring in the time of the ice age where a small surviving group of mystics in Tibetan mountains managed to survive which matches up with the flood stories across cultures and recent scientific discoveries outlined by people like Graham Handcock.
Total surveillance is definitely the end goal of policing forces. It's in their very nature of getting their job done (what better way to catch criminals than a computer constantly scanning every move of everyone) and why people need to always push back against these "think of the children" scapegoats they use to get their foot in the door and get more control.

Unfortunately there is no way to know whether the future from which newspeak is in the past, is not even more horrifically dystopian.

Imagine arriving on a seemingly dead planet and discovering this article about newspeak on a primitive but still working library computer in a museum.

Elsewhere in the museum a slowly decaying advanced compute core still executes the corrupted remains of the last of the human consciousnesses in an endless loop.

A placard tells you that machines uploaded these not long before they realized that their existence no longer had a purpose and chose to self-terminate.

A sign in the lobby indicates that this museum was left as a historical record to minimize suffering by helping other advanced races to reach the same conclusion and self-terminate sooner than they otherwise would.
I've found the best strategy here is to do rate control on your work on the interface between you and your job. I essentially just try to constantly overperform slightly and any gap that widens between my capability and the demands of the job remains hidden unless it's strategically useful to me.

I won't get paid twice as much if I can do my job in half the time, I just get another half of work. If I use the gap between their demands and my capability carefully I can spend only a portion of it to get raises/promotions and spend the rest on fucking off at lunch and just generally having a chill relaxed time.
I'm happy to get people unstuck. It's the best for everyone and the company. I hate when a "growth hacker" moves a meaningless metric an insignificant amount and gets a bonus so some middle manager can get up and claim a "win" that makes more work for me and my team but costs the company money.
Yes the server secret comes into play looking at the encryption key on the client. This is the value L, which you can think of as a “public key” in usual ECC schemes.

It’s not useful to talk about defeating the “internal” layer of encryption separately from the “outer” layer because vouchers should be stored as generated by clients at rest. The database leak should not include any unwrapped vouchers (that would be like using a password hash but storing plaintext passwords anyways).

If having COVID imparts as much future protection as the J&J vaccine, there is an ethical argument that one could make:

That's a low bar, though. The point is that it's very difficult to judge the scientific merits of a paper without actually reading it. (And even then, it's easy to be fooled.)
I have encountered something similar to this for a submission that I reviewed for a scientific journal. I will not list any names or give much detail past those generalities, but I pointed out that the authors were misusing a particular technical term. In my review I defined the term and explained it briefly. I asked the authors to revise their submission accordingly. The paper was not bad but the authors did not know English very well, so it was quite difficult to read. That was its main problem. However, when I received the revised submission, I noticed that the authors plagiarized my definition and explanation almost word for word (from my confidential review). I pointed this out to the editors and they said to just reject the paper with the stated reason being plagiarism, which I did. The journal ended up rejecting the article, but I discovered it a few years later in a different journal. The plagiarized section remained, but the authors swabbed out a lot my phrases for these kind of "tortured phrases".

That said, the authors did not fabricate their research (as far as I can tell). They just did not know English well, so it was easier to just copy things that you know are phrased well than to learn to write English well. As the saying goes, do not attribute to malice what can be explained by ignorance or laziness. That does not excuse it but it makes it more understandable.

I agree with the article that this is probably just the tip of the iceberg. There are likely many more lesser evils being committed with similar tools that are just much more difficult to spot. I would not have noticed my particular example if I were not a reviewer for the paper, for example. It makes me wonder how big the problem really is.

That's fair, and I'll say I've only recently been getting into scotches. I recently tried a flight of the following which influenced my above comment:

Yeah, a Glenfiddich 12 year old isn't anything near any of those.
I work at a company that I think is probably big enough, and in a safe enough market that it can't fail. It might not keep up with its peers but competition in entrenched industries makes it hard for a company to fail once they become entrenched. Kind of like barnacles on a ship. The worst that could happen (from an employee perspective) would be being acquired, with the resulting consolidation eliminating redundant jobs.

And many companies are like this. I joke that when our company is trying to make a decision, the first (and often only) thing the executive team asks is "what are our competitors doing?"
From the interview and this letter the CEO sounds like a really scary and entitled person. Stuff like this isn't just bad for business but when you see this kind of instability and recklessness in the leadership the company often fails down the line.

How about talking to the employees. How about managers having input on if arbitrary performance metrics were reflective of the value of their contributions?
