Musk might just be venting on Twitter, as another commenter has suggested, but one way or another these tweets might turn out to benefit him. From what I can tell based on both personal and online interactions, it seems to me that U.S. public sentiment has been shifting against the lockdowns recently - and not just among some fringe protester groups, but among all kinds of demographically and ideologically different groups. Musk's tweets might appeal to those people and make him more popular. I'm no fan of, for example, Musk's lies about self-driving technology being just around the corner. But say what you will about Musk, he has a powerful talent when it comes to publicity.
This is actually quite common in COVID-19 and SARS patients, Chris Cuomo from CNN popularized the "waves" that it comes in with his personal ordeal. Some evidence that this virus either replicates very fast, or hides from the immune system (could explain the asymptomatic people) until the right moment when you feel weak after a workout. Eventually your body will 100% defeat it, but you should probably take it easy and socially distance until you have 72 straight hours without a fever.

This is common in Chickenpox too, where it hides out and then re-emerges later in life as shingles near the age where your immune system starts to weaken.

Good luck, you'll get through this.
You mentioned "if one person on a team of 10 engineers spends 3 whole days shaving off even 30 seconds on a task done by everyone only 5 times a day, we would have gotten a complete return on investment over a period of just 6 months".

How did you get 6 months? can you shed some light on the calculation? Thanks!
Massive infusions of cash from Congress & the fed will do that for you. It’s far, far, far too early to draw conclusions about long term recovery.
That may be the plan, but SoftBank and the Saudis are not exactly smart money.
Venezuela is the watched pot: it should have boiled by now! Venezuelans haven't violently overthrown Maduro because they mostly consent to the results of two somewhat-democratic elections. He lets his supposed "rival" Juan Guaido prance about the country unmolested so all Venezuelans can laugh at the impotence of CIA. With continued sanctions and the price of oil at long-time lows, "natural" pressure on Maduro should be running hot. Instead, that same low price obliterates CIA's theoretical incentive to install a subservient petrostate. They've redeployed their ratfuckers to Nicaragua.

If a USA president had been subject to massive bias from nearly every news media corporation, he might be tempted to honor an independent news outlet that attempted to report with objectivity. Oh, wait... that actually happened this year, at the "State of the Union" speech.

When we fall into the trap of running to wikipedia every time we're confused by world events, we can't be surprised that the war media continues to lead us around by the nose. If we step back and see the pattern, we begin to discount every story that leads us closer to yet another stupid war. Every day this month, it has been obvious to non-Americans how deficient our system is. Every other nation on earth has responded more reasonably and more effectively to this virus. Venezuela is among those nations.

I presume the context is the United States where a typical loan requires no more than a 20% down payment, providing 4:1 non-recourse leverage, with 3-4% interest. Outside of home mortgages, that sort of sweet-heart financing is only available to the very wealthy. When you factor in retained equity, at the end of the day, unless mobility or liquidity is exceptionally important to you, buying absolutely makes sense for the vast majority of Americans who can afford it. The home mortgage interest tax deduction is just icing on the cake.

That housing prices don't appreciate as much as the stock market is not dispositive. Now, once you already own a home, then of course the fact that the stock market provides higher returns matters for subsequent investment decisions. The calculus of residential ownership isn't nearly as favorable for non-owner-occupants. For small-time real estate investors banks offer you less leverage (3:1 or worse), higher interest rates, and your risk exposure is greater because you're purely speculating--whereas with owner-occupier you were presumably going to be living in that market, so you're only marginally speculating.

The situation is different in many other parts of the world with different socioeconomic policies (e.g. expensive mortgages, high down payments) and real estate markets (e.g. more common for housing to depreciate in value), but that's irrelevant to the U.S. You can't say whether owning makes sense or not without accounting for all the opportunity costs, which can vary widely. But in the U.S., generally and historically, buying a home adds up. Maybe the U.S. is worse off for incentivizing homeownership, but it is what it is.
Some positive comments here on NiFi. I found it to not be that great.

I used it 4 or so years ago but things may of changed.

1) you get a big canvas which is just drag and drop. The canvas can get huge and scrolling across the screen etc

2) leads on from previous, vary easy to go and accidentally drag something to the wrong place or stop a paticular flow

3) some flows get stuck then a pain to restart

4) it was hard to version and do the dev / test / prod deployment. You got a huge XML file if you export the flows which do not diff
5) it’s hard to test. You can create your own processors and unit test them then deploy the jars but that doesn’t seem the nifi way. Instead you use the built in processors and glue them together. They are configuration essentially, configured in a GUI so you can’t test them programmatically. You can use groovy scripts support which is built in but you hit the same issue, how do you test inside nifi

6) no multi tenant or weak acls. Bit of a pain if want a shared nifi server as you have one massive canvas

I can see the appeal if a team had their own nifi instances but I find it still a cludge and writing a small specific app / microservice far simpler and more efficient for ETL pipelines etc

Why does it seem like both sides seem to be so sensationalist about Sweden. They have middle of the road all-cause mortality and most recently their sero studies suggest an extremely low IFR but that got pulled due to bad randomization of test subjects so that might go up to middle of the road for Europe for Sweden too. They haven't performed great and not poorly either. It's strange to see people so polarized over them.
Does one need exposure to direct sunlight, or sunlight coming via glass windows works?
Yes, you would still have to create a new "Secret chat" to have the e2e.
The reason for that is explored here: https://telegra.ph/Why-Isnt-Telegram-End-to-End-Encrypted-by...

It's their approach and I'm personally ok with it. Due to my friends I use FB messenger a lot and they say it will take years to be e2e encrypted, so I believe it's a fair compromise from Telegram.
You can read up on it in the book by Dr Holick. He recommends 4000IU daily, but if you're afraid that's too much, go with 2000IU/day. I take 4000IU daily since several years. Get a test before you start, so you have a base value. Test again after a month or two maybe three, and see what the change is.

With sun exposure, the book recommends the following. Go sit in the sun on a sunny day, until you get a mild rose burn. How long does that take? Divide that time over a week, and you're safe. This rose-burn time depends on the time of year, how high is the sun in the skye? How clear is the skye? What is the time of the day? So this value changes a lot for people in norther Europe, compared to people living in Africa.
I mean, same - my main point was that it's not sustainable. Sooner or later SoftBank and the Saudis are going to run out of patience, so just enjoy it while you can.

Car manufactures favor margins over moving metal. They've learned that long loan terms don't reduce sales, as most people define affordable to be, they can afford the monthly payment.

And since manufactures own the lending arm, and the sales arm, they enjoy higher margins, plus more in interest payments. Not everyone is going to qualify for that 0% interest. Plus, it keeps dealers happy because they can squeeze in bullshit fees to pad the sale price.
The Earth moves in an orbit around the sun, so the only way this would be a problem is if the asteroid were not visible at all until only a few months (or even less?) before impact.

Yes. All commercial aircraft have regular maintenance + inspections at time + mileage intervals.
Musk is worth $38.5 billion based on his current Tesla stock holdings at their current valuation.

If he hits the trigger in his compensation package, he gets even more Tesla stock which will vastly increase his net worth on paper

Also, Musk is loaded with debt because he leveraged his stock holdings to live a very lavish lifestyle, including multiple residential properties, vehicles, and very expensive dining choices.
> most people can’t write and don’t know how to write something that’s valuable to the reader

...yes? And?

99.999% of people's comparative advantage is not in their writing ability.

Add to this that learning to write to a quality level required for effective, efficient communication, is a far higher burden to place on someone, than the level of fluency required for basic exchange of information; especially for people for whom English (or whatever language is being used) is a second language.

Taken together, this implies that for most people, learning to write well—i.e. learning the skill that, having possessed it, would make you into a competent essayist—would be a waste of time. Just like learning abstract mathematics would be a waste of time. (And I say that as a professional author!)

Most people intuitively know that learning to write more effectively isn't the best use of their time, and so most people don't try.

This "hack" is far less costly, and therefore far more likely to get adopted by these people, and therefore far more likely to actually improve the experience of reading the average communication in a large software project (which tends to involve people of varying communication levels.)
Oh sure, of course! - just as with a rental situation where the landlord does a last inspection to make sure everything is in reasonably good condition.
Tesla is going ham with thixotropic aluminum casting. Big-ass machines, big-ass castings, no heat-treat.

The goal is to get that down to a single casting. Not only does this simplify production further, but you can do it with no machining afterwards, no datums, nothing. You just tap the holes and put it together.

> I keep wondering how many of the psychological problems arise from people having children much much later in their lives than used to be normal

This is also something I have been thinking about for a long time now. The human body, instinct and mind seems to be made to raise children. As a new parent, you have zero experience in handling a child. Yet after just a few minutes, your instinct kicks in. You somehow know how to hold the newborn, despite the fact you have never done this. You try everything to keep it warm and comfortable. You realize that your body is perfectly shaped to hold a baby with one arm, and that the baby instinctively contracts its legs for a perfect and secure fit. Despite the fact that crying babies sounded the same to you all your life, you can suddenly distinguish the crying of your own child from that of others from the beginning and from a large distance. If your baby cries, you instinctively know what the problem is. Without making a conscious decision regarding this, your absolute number one priority is suddenly to keep this child alive, whatever it takes. The thought that you would fight anything or anyone attacking your child, until the bitter end, suddenly seems completely natural. All of this can not be made clear to people without children, which is basically why parents like to talk to other parents. Raising a child certainly is one of the most extreme things a human being is capable of, and yet most parents manage it. To me, it would not at all be surprising that not using this potential may lead to serious psychological problems.
I have the hope that AR fixes this with new glasses and arranging virtual dashboards around the house.

The AR technology is already there, only the glasses are missing.
the more precise wording would be that you're comparing different time periods and then using that to extrapolate rationale. that's an error of statistical reasoning.

the more accurate exapolation would be relative to the first 4 months of every other studied emerging disease, considering the estimated errors of each of the important variables. you'd fit the various current studies on corona/covid, considering the high uncertainty as (large) estimated error, and providing a range of future outcomes with probabilities on them.

instead, you're asserting your worst possible scenario as the most likely outcome.

~~~~~~~~~~~~

now on the idea that we're entirely too blasé about preventable mortality in general, i agree. if we rigorously and intelligently attacked auto accidents, if we addressed cardiopulmonary diseases caused by pollution and poor habits, and if we regularly shut down the economy for the past decades because we want to reduce the hundreds of thousands of contagious disease fatalities every year and had the socioeconomic safety nets in place for that all along, then the current actions would seem more reasonable.

instead, the response is out of proportion with our own past actions because of panic and fear. it happened with 9/11, mass shootings, fukushima, and everything else. the herd is not good at reasoning about rare and novel mortality events.

Examples of Specification Gaming in ML
Every time you drive, you aren't hit by cars that simply had a yield sign. You see those cars, and you see them before they have even slowed as they approach the yield sign, and every day you gamble that they are going to yield and let you pass without hitting you.

So, even though the cars are approaching from behind the cyclist, they may see the cars approaching. And just like any right of way situation, they assume the cars will stop. Just like how you don't slow down just because you see someone waiting to go right on red.

Note: the OP intersection has gained stop signs over time to help avoid collisions.
That is the route Rivian is taking and Ford just announced the cancellation of their first planned model.

Even if we create a vaccine how are we going to vaccinate people in conflict zones? If we can’t immunise everyone with the oral polio vaccine, then we have no chance of immunising everyone against SARS-Cov-2.

There is a possible ecological solution - we drive the dangerous strains to extinction by deliberately spreading a harmless strain. Unfortunately few people seem interested in investigating this idea.

I remember reading that this airport specifically has a contractor that specializes in storing (and presumably maintenance).

As airlines start flying more, they will likely send a percentage of their mechanics to this airfield to speed up the tasks.
This systematic meta-analysis paper[1] may be more convincing. The popular youtube COVID-commentating Dr. John Campbell did a review of it about a month ago[2] and has some good comments on the meaningful statistical power and experiment design.

The overall takeaway is this: in people with Vitamin D deficiency (which is very, very common), continuous daily supplementation can lead to up to a 70% reduction in contracted viral respiratory infections. It has a smaller effect the less deficient you are, and is not associated with any adverse effects.

From Wikipedia: “according to some research, the tolerable upper intake level (UL) is 4,000 IU/day for ages 9–71 (100 µg/day). Other research concludes that, in healthy adults, sustained intake of more than 1250 μg/day (50,000 IU) can produce overt toxicity after several months”
I’ve personally gone from “should I upgrade from a Mazda 3 to a Tesla 3” to “Should I just not get a car at all once this lease is up?” In a shockingly short period of time.

We currently have massive unemployment, and low quality, toxic food. I think rather than giving everyone a "basic income" to purchase that inferior food, we should give them jobs producing better food, and the overall increased price of food wouldn't be any worse than the cost of UBI.

Hi - Startpage person here. Maybe I can clear some stuff up.

1) Startpage provides Google results, but Google never sees you. Startpage submits your query to Google anonymously, then returns Google results to you privately. For more info on we keep your search private: https://www.startpage.com/blog/privacy-awareness/how-does-st....
2) Startpage is HQ'ed in the Netherlands, meaning we don't have to comply with US government or law enforcement and comply with EU/Dutch privacy laws such as GDPR. Also, we’re not likely to receive requests by governments to hand over user data – simply because we don’t have any.
3) In 2019, Startpage announced an investment in Startpage by System1 through Privacy One Group, a wholly-owned subsidiary of System1. With this investment, the plan is to further expand privacy features and reach new users. (Lots of new privacy features in the works!) The Startpage founders have control over the privacy components of Startpage. And! After conversations with the privacy community, Startpage was recently relisted in PrivacyToolsIO. More info on that: https://support.startpage.com/index.php?/Knowledgebase/Artic...

i loaded up on a bottle of costco vitamins and d3 supplement before we went on lockdown. There seems to be something in the multivitamins that i'm allergic to in high quantities, i.e. after taking them for 3-4 days straight I'll start getting hives. I reduced consumption to 1 mv tablet every 3 days and no problems so far. I'll probably increase d3 intake to 1 2000iu tablet per day and see how it goes.

Every time I pick up my phone to check a piece of information or complete a simple task, I am presented with some other distraction that threatens to sidetrack me. When I don't want to be distracted, I often leave my phone in another room, turn it off, put it in a bag or even leave home without it. I've often thought of creating my own eink devices with focused purposes to help me get the information I need, while avoiding the distraction of a multipurpose device like a phone.

At work we moved from zoom to https://team.video, which has emoji reactions with sound effects that are ... a little bit more "grown up", if I can say it that way.

We actually really use them all the time. What's great is that especially in bigger groups, it's so much easier to read the room when you can see everyone's reactions. Without this, when people are quiet, you never know whether it's because they're not engaged or they're being polite, or they don't want to find the exact moment to unmute and interject verbally.

I can't imagine going back to zoom/hangouts now.
