It remains to be seen over the long-run whether antibody levels correlate inversely with either risk of: a) _any_ Covid infection or b) _severe_ Covid infection.

Antibody levels are often cited as prediction surrogates early on because they are easy to measure. Occurrence or recurrence of infection, irrespective of antibody levels, of course, takes time. Also remaining to be seen is the role of T-cell mediated immunity in reducing the severity of Covid infection. If that role is significant, then declining antibody levels may be less worrisome than people believe currently.
strange use for a microswitch, must've had access to dirt cheap switches; IR diodes tend to be cheaper and less faulty for that kind of use.

all the microfluidic/lab-on-a-chip stuff is neat, i'm thankful that someone decided to tear something like this apart and show us.
So you are talking about something like SQLite-as-the-API? I was a big fan of this idea for a while. Difficulties in streaming query updates from SQL dbs and difficulties in working with deeply nested, hierarchical data made me shy away from SQL though.

Having a client-side relational db to work with would remove huge amounts of complexity to most client apps though.
I don't think they're unaware of the questions. In fact, in the half-dozen or so cases I have any direct interaction with I'm certain they're aware of such questions. My point is exactly that they have other forms of incentives and reasoning that cultivate a willingness, or in the worst cases a zealotry, to entertain what their relative out-groups would consider a contradiction simply as open questions that their in-group permits.

I used the example as a representative for the kind of issue involved, not as an exhaustively defensible one. :-)

Principally I think we're in agreement. There seems to be quite a bit of analysis and consideration about what's going on that's through the lens of a kind of "enlightenment" reasoning wherein it's purportedly obvious that the pursuit of facts is intrinsically valuable, and so people not arriving at that value must be that they just don't know how to get there or are being lead astray.

Alternatively, I would suggest that for almost everything that almost everyone deals with in their day-to-day and/or finds reward & incentives for, there's practically no value to facts. Often it's the inverse. "Bullshit" pays. Sometimes socially, sometimes financially, sometimes both. In the case where such "bullshit" has become a subculture of its own, suddenly facts have negative value.

For whatever it's worth, this relates to one of my annoyances with the general startup ecosystem as it exists (to bring it around to HN-esque territory) I've been told (more than once) that the fact I have integrity is going to make my life harder as a founder. It makes it harder to sell. It makes it harder to fundraise. Etc. Those people are absolutely right. Because both selling and fundraising have a built-in incentive toward BS. "Fake it 'til you make it." became a social and financial good, and so people do it. Because if they don't, they automatically start out at a significant disadvantage. My personal bet is that my biasing toward integrity approach pays off in the long-term when the builders, not the brokers, get their cyclical day in the sun again, and in the meantime I can still be square with myself. That said, I very well could be wrong, and I unnecessarily made both the short term and the long term harder than they needed to be.
> and in the case of the latest variant, we know they are not effective

I assume you are talking about stopping spread, which could be accurate. I further assume you are not referring to reducing illness severity, because they obviously are effective at that. But that benefit extends beyond the individual insofar as it reduces strain on the overall healthcare system -- ensuring that even those who have injuries or illnesses that have nothing to do with the disease in question receive adequate care. Therefore a vaccine mandate (or restrictions placed upon those who aren't vaccinated) can still be justified.

This would set alarms off for me. In my opinion, legality != morality. Just because something is legal doesn't make it ethical and vice versa.

I don't think this is right. It moves the filter forward from "no life" to "no intelligent life" (If we have a TON of examples – remember, we are also a data point. so even if we find 200 planets with dead multicellular life, we still have 1/200 making it to spacefaring — that's a huge % when extrapolated out to a galactic scale! It's a large enough % that I don't even find this to be a meaningful prior adjustment).

It also adds no information as to which, if any, filters are in front of us. How would "lot of dead fish" help us understand "do civilizations destroy themselves with nuclear weapons"?
Money has no properties or value. Both usd and bitcoin have an intrinsic value of zero. Unless you like staring at bills depicting national heroes, ofc.

The reason you want money is that you know people around you want it and you can use it to acquire goods.

Now, what makes USD a superior currency:

- you don't need internet to use it

- you don't need third party centralized unregulated services to use it (unless you want to run a full node)

- you can exchange it with ease, in multiple formats. Give your daughter 0.0000000000045 bitcoins for lunch.

- no fees for using it.

- practically scales to infinity vs few hundreds transactions per minute.

- doesn't require energy to run. The energy required by each transaction covers the needs (heating and transport included) of a family of 5 for days

- very stable, I know how much things will cost a minute, hour or days from now, so my daughter eats even if whales are short squeezing markets by lunch time.

- used mostly to buy services and goods vs never used to buy anything but other currencies.

- inflationary, creates pressure to spend and invest rather than hoarding. Deflative currencies don't make sense to spend. Why would I buy X today at n bitcoins, if the deflative nature of bitcoin will make it more scarce and will make X cheaper. Why spend bitcoin today, if in few months there will be new highs and I can buy even more and so on.

- de facto currency of international trade. Some countries like Russia try to do international trade in euro. What can have higher consensus?

- 250 years of history

- regulated through democratic means and under clear laws for the benefit of most; vs unregulated, mostly owned by few early anarco capitalists (i know people with thousands and thousands of bitcoin) and offshore scams. Basically very few people own most of bitcoins there are out there, very few people control most of the network.

I think the list can get infinitely longer but it gets boring.
I have run a Raspberry Pi Zero W with 5mp camera and MotionEye software outside for 3 Christmas seasons to control an animated display. I trigger on movement and capture still and video images to the SD card and automatically upload them over WiFi to my ftp server. I can monitor a live stream anytime too. MotionEye does everything.

This setup runs in a small waterproof enclosure and runs a bit warm (35-45C) that dissipates any condensation or rain on the fisheye lens. This might help you with snow accumulation.
I agree with everything you said. I'm under the impression that flat earth does not possess an actual threat. If that's true then there's a difference to people believing vaccines are evil, an idea that also advocates action - to not take vaccine, which is capable of causing actual damage. Or believing in homosexuality is a sin - which advocates disrespecting or trying to convert homosexuals which can make people's lives harder. So curious to know how big of a threat flat earth truly is today.
Over-supply? A lot of third world countries would be happy to take it. We're still far from offering the entire world even their first shot
There has to be something mistranslated here somewhere.
I actually like flat earthers as an exercise in epistemology.

We all know that the earth is not flat, there are countless evidence, and a lot of them easy to try for yourself. And flat earth is not a dangerous idea. The only thing you risk by believing and trying to spread the idea is ridicule. It is the perfect playground for trying "alternative" ideas.

So go look at all the flat earthers arguments and try to take them seriously. Some of them are actually great. There is even one that mirrors general relativity: the earth is a constantly accelerating disk, this is what creates gravity. Of course they are all wrong, but disproving them require actual thinking.

When you have trained yourself on the flat earth, you have completed the tutorial and you can now move on to the real subjects: climate change, vaccines, quack medicine, etc... Here you have actual believers, and they have ideas that can be convincing and dangerous. People die because of quack medicine.

To my knowledge, no large society in the past two centuries, regardless of economic systems, has been a particularly good steward of natural resources. You're going to have to do better than that.

Deflationary currencies have been an abject disaster in all fronts, and there is nothing particularly contentious about them from even the most contrarian of positions.
> 1 BTC is worth 1 BTC.

tautologically true, but irrelevant. That's like saying gold costs 1 ounce per ounce, and that price has never changed in the history of its existence.

Current economic pricing happens with USD for most activities, and thus you need to be pricing BTC under USD.

Until the day people would easily accept BTC directly (and hold it instead of converting it into USD), you cannot price BTC in BTC.
If you consider articles and research that the public paid for and suddenly don't have access to, to be piracy, then sure.

A soul is infinitely more important than a temporal sickness and God is infinitely more merciful and wise than our limited capacity/knowledge can comprehend.

John 3:16-21
"16 For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life. 17 For God did not send his Son into the world to condemn the world, but to save the world through him. 18 Whoever believes in him is not condemned, but whoever does not believe stands condemned already because they have not believed in the name of God’s one and only Son. 19 This is the verdict: Light has come into the world, but people loved darkness instead of light because their deeds were evil. 20 Everyone who does evil hates the light, and will not come into the light for fear that their deeds will be exposed. 21 But whoever lives by the truth comes into the light, so that it may be seen plainly that what they have done has been done in the sight of God."
I was thinking about immunity generally, from a Shannon information theory perspective. It's impossible that the human body has an infinite ability to absorb immunity, because otherwise we could store an infinite amount of information. Therefore, there must be some kind of forgetting that happens. Likewise, the body can only learn so much from repeated exposure.

Is anyone aware of any writing that explains immunity from an information theory perspective?

I suspect page 23 continues onto page 93, but that's about as easy as this puzzle ever gets. Each page begins and ends in whole statements and there's not, for example, any dialogue split between pages. The occasional poem fragment is the only easy clue you get.

The rest of it likely requires paying attention to the subject(s) and setting on each page and gradually assembling them. I have no expectation of ever solving it, and if I ever do get the pages into some kind of order, I doubt I'll be completely confident about my answer.

Some kind of NN model could probably be constructed that would do a pretty good job of getting it mostly in order. Somebody else might find that to be a fun problem, but I picked it up for its potential to be a long-term amusement.

I'm curious about the argument that giving too many boosters takes away the vaccine from "people in low and middle-income countries."

Surely we have the capacity to make enough vaccines for everyone by now. It's just a matter of economics. Giving more boosters really shouldn't reduce supply, if there is money to make vaccines for everyone in the lower income countries, they will be made.
> I think they are making these strain specific boosters. But it seems “they” want to keep it quiet until they are ready to release them.

There's nothing quiet about it - Moderna has already publicly announced[1] that they're nearly ready to take their Omicron booster to clinical trials.

Something is not right. CNN reported the same study, with contradictory quotes from the same doctor:

Fourth vaccine dose boosts antibodies, researchers say, but likely not enough to prevent Omicron breakthrough infections

According to Regev-Yochay, the third dose resulted in “much higher antibodies, neutralization and the antibodies were not just higher in quantity but also in quality” than the second dose – but the fourth vaccine did not show significant antibody increase.

”Maybe there are a few more antibodies but not much more compared to the third dose,” said Regev-Yochay.

--- cnn.com -----
"We have a follow-up of the Pfizer vaccine for two weeks now, and we have a follow-up of the Moderna vaccine just for one week at this time point. And what we see is that the Pfizer vaccine, after two weeks, you see an enhancement or increase in the number of antibodies and neutralizing antibodies -- a pretty nice increase. It's even a little bit higher than what we had after the third dose," Regev-Yochay said.

This is exactly why I always find it fun to read discussions about nuclear power on HN. Lots of people here are hardwired to only think in terms of software (where it's all 1s and 0s and you can do whatever you want), and then they apply that thinking and logic to real world engineering fields and the logic collapses. Doubly so for the nuclear sector because you can cause catastrophy if you aren't careful.

I grew up in West Virginia, and I can guarantee that virtually none of my teachers could explain how to derive most of what we were taught from first principles. There were a few very bright stars in my list of teachers, but most were really phoning it in and didn't understand well enough to teach anyone aside from reciting from the teacher's edition of the book.

When considering how much power the federal government should ideally have, it’s wise to always remember that: one day, a party that you dislike will wield that power. Don’t think about what good you could do with all that power (because you’ll likely undershoot your positive intent anyway), but think about what bad someone who thought the opposite of what you want could do. It’s easier to destroy things than to build then up, so even if they also undershoot their positive intent, they can likely deliver on the things you’d find negative.
Try a 3-way M-M join. Or recursive CTE's for hierarchical data. It always looks clean with simple examples. Data these days is much more nested and inter-related.
It's a pretty nonsensical article to be honest. Experiments to demonstrate that the earth isn't flat, like Foucault's Pendulum happen in plenty of schools, in fact pretty much every physics, biology or chemistry class does plenty of experiments to show kids rudimentary science.

Flat-Earthers can disprove their own flat earth theory in ten minutes if they wanted to with high school science. The reason they don't is because most of them are insane, have like the author a pathological resistance to justified authority (which has its place in science as well), or just want to prey on gullible people which often is pretty lucrative financially.
‘Netaverse’ VR-Like Nets Experience Revealed for Basketball Fans

> When an infrastructure engineer tells you they prefer MySQL. It’s probably because for them it’s simpler/easier to operate it. Backups, replication, failover, upgrades. Accomplishing what is most important to them.

> When product engineers prefer postgres, it’s usually because of something like postgis, jsonb/hstore. Some feature they can use in the app to build something faster.

> I hope this helps in explaining why you often see the infra orgs of many large/high scale companies choose mysql.

Isn't that missing a very important reason which is that

(a) MySQL was better known in the period 2000-2010 when is when many of the large/high scale companies started to create their infrastructure, and

(b) Your choice of database tends to be sticky
> a lot of "they should have just given them a laptop" commentators

Lol...I'm one such commenter on this submission.

This logic only works if you assume a direct, monotonic relationship between quantity of devices provided and net utility imparted to society.

> Making a special BOM to make a "cheap" laptop would have walked into precisely the same problems OLPC hit.

You don't explain why you believe this to be true. Different technological implementations face different problems. If that were not the case, engineering would be a purposeless discipline. And there is no reason why "cheap" has to be a component of a philosophy behind contributing to the development of third-world economies and the communities from which those economies draw their manpower.

> Post-hoc reasoning.

The book itself is a reflection on the project, so "post-hoc" should carry no dirty connotation. Moreover, the problem of providing technology to poor kids persists in the present day. Today, we see a very different device landscape and cost profile versus back in the year 2005.
