Wow, anyone reading the source paper in detail (or trying to take away conclusions) has to know that the stats are really, really rough.

The authors are almost just doing internet desk research -- counting the number of Covid deaths/cases and just plotting that against the average Vitamin D level in the population of each Indian state in general. Based on a couple thousand healthy patients of the general population. (BTW, I think it's really important that everyone learn to see through the math/symbols/technical jargon when reading such research papers to understand the populations really being studied. All those r and p numbers are meaningless if the underlying patient data are flawed.)

That is really rough. I could not imagine this would be credible if you substituted for example (just to think about it locally with a population you might know), "New York" for "Maharastra" state in the plot and asked if you believed the strength of finding that average Vitamin D level in New York state correlates with Covid death rate. How about for Florida -- would that be believable too? And also, the noticeable points making up the perceived trend are so few, and the points are not even weighted for population size (?)!

Much more work in detail -- at the patient level with Vitamin D measurement -- would have to be done to be credible. I would not act on this information in the present form.
And they can be pretty good if you make them right!
I’ve been taking vitamin D daily for the past year. I came across the study below recently that suggests that Coenzyme Q10 could also reduce hospitalization rates for COVID. This is another low cost over the counter nutritional supplement. It’s also called ubiquinone.

Agreed, not with this particular design. However, you can absolutely do this just ternary numbers. You loose the ability to encode 3^n states (and are stuck w/ just 2^n), but the middle state can then be repurposed to indicate if the computation is complete (or not) as of yet.

I basically used this sort of design in a dual-rail logic framework which had 4 line-states per "data" line pair, two of which were real data bits, a third indicated unknown vs. unknown, and the fourth was unused.

See https://core.ac.uk/download/pdf/82751815.pdf, but beware that even though it doesn't look at all like ternary numbers in use, it absolute is.
At this point in my career, I just run away from a company that operates that way.

Code tells me what the coder was doing. It does not tell me why. If the why is not blindingly obvious, it deserves a code comment.
It sounds like you're correlating forgetting who you were and the phone, but you should be correlating the LSD and forgetting who you were. These drugs de-activate the "ego" forming parts of the brain, the parts that make us feel like an author/being/center of it all.
Not all countries do this.
> The study in question will be randomized, national and multi-center, carried out double-blind, and should involve teams from Assistance Publique – Hôpitaux de Paris, Sorbonne University and Inserm. It is expected to include approximately 1,633 medical and non-medical caregivers, working in a health establishment, non-smokers (or former smokers who have quit smoking for more than 12 months), without a history of infection with COVID-19, and working with patients (with or without the virus).

> The researchers will administer nicotine patches to some of the participants for a period of 4 to 5 months, and then carry out a follow-up for 6 to 7 months. Of course, it is still too early to conclude exactly how nicotine interacts with the coronavirus. However, if nicotine is indeed confirmed as a protective factor, NRTs including e-cigarettes could play a pivotal role in controlling this pandemic.

Very curious to see how this goes. I would also love to see information as to why nicotine works this way, and if there are any non-nicotine options that have similar effects? Interesting stuff none the less.
The first paragraph says:

> The researchers had estimated the rates of daily current smokers among COVID-19-infected patients and compared them to the rates of daily current smokers within the general French population, after controlling the data for sex and age.

So, assuming they correctly controlled for age, then no, it’s not “anti-survivorship” bias. (“Casualty bias”?)
That’s a fairly heavy lunch.
Malnourished people are more susceptible to disease? Shocking.
Even if you call that a "balanced" day, that's 7 hours straight of using a tiny mobile device, when you could use an actually ergonomically sound device with better I/O speed and higher resolution, i.e. an actual computer. People would get those tasks done faster with less strain on their body if they used a different machine.
There's two kinds of watches:

1) Mechanical Watches

2) G-Shocks

If you're putting something other than those on your wrist, that's fine, and you can dork out all you want, but just please don't call it a "watch". The Apple Watch is an insult to every horologist and a disgrace to everyone with an ounce of class. :) Yes I jest, but actually not all that much.
It's remarkable how similar Swift and Rust are w.r.t syntax.

Rust, Swift

let x = 42;
let x = 42

let x: i32 = 42;
let x: Int = 42

let _ = 42;
let _ = 42

let pair: (char, i32) = ('a', 17);
let pair: (String, Int) = ("a", 17)

let (some_char, some_int) = ('a', 17);
let (some_char, some_int) = ("a", 17)

fn greet() {
println!("Hi there!");
}
func greet() {
print("Hi there!")
}

But, the languages are so different, for instance in Swift

let x
x = 42

let y = 13
let y = y + 3

Wont fly for instance. I am trying to come up with the simplest explanation possible for this but I can't - goes to show how much I understand either of the languages.
Ah, missed that, thanks. Even more interesting then!
Even at the time most people thought his removal was a bit odd and unneccessary.

Later on with the leaked cables, we found out that it was largely because he was trying to create a gold-backed pan-African currency that would have harmed French central banking interests in the region.

One of the first things the "revolutionaries" that ousted Gaddafi did was create a central bank. While they were still fighting for territory.
1) Fully remote
2) 15 bike ride
3) Fine. I live in 500 square feet though which has had some sort of unquantifiable mental toll on me though.
4) Less overall work which is nice. Easier to just turn of my laptop at the end of the day and no one can swing by and drop more stuff on my plate. I do miss the interpersonal aspects of the office at times though.
5) A lot of the folks I work with or have worked with are changing jobs. If team culture is great but you’re underpaid it’s now easier to leave for more money/new opportunities without having to tell your team that you’re leaving to their face.
6) I miss working in the office at least part of the time. Perhaps I’ve idealized it though and would not feel the same way after a full week of commuting.
Scroll up and down in the list.

The issue is that a one-line quip is generally not a driver of good dialogue.
N95 masks are only really effective when people wear them properly.

I wouldn't be surprised if they were less effective than the regular masks when worn improperly, because the higher resistance of the N95 filter material means more air goes through the gaps (whereas the regular masks are breathable enough that air still mostly flows through them). I would also expect acceptance to be much lower due to higher breathing resistance.

If I recall correctly, the initial US infections came from Europe not China, so Paul's hesitance to a China-specific travel ban wasn't a bad call.

Island and smaller nations have some capabilities as far as population movement controls that the big ones don't have or can't sustain for as long. Eventually COVID will come for all, suppression strategies only allow a nation to adjust the timeline.

This study shows an unexpected very early circulation of SARS-CoV-2 among asymptomatic individuals in Italy several months before the first patient was identified, and clarifies the onset and spread of the coronavirus disease 2019 (COVID-19) pandemic. Finding SARS-CoV-2 antibodies in asymptomatic people before the COVID-19 outbreak in Italy may reshape the history of pandemic.

Wow, this is an excellent critique. I don’t expect any language to be perfect, so I’m personally alright with my investment in Go. Nonetheless, I love when people share the ugly parts of software so clearly so I can anticipate and avoid similar problems. Since I use Go, I actually got a lot out of this and enjoyed reading it a lot.

Go’s simplicity scared me a lot from the outset - there is no free or easy solution in software. Everything is a trade off. As such, I think Go is an excellent tool for prototyping dumb solutions for relatively simple problems. Or at least, for modelling solutions around simple parts of problems while ignoring complexity until later. On our team we see anything important as something we finish fast with Go/Python, then we do it right with Rust when we fully understand it.

As a tool for getting things done quickly with that pretence, I’d argue that Go is an awesome tool. I would be afraid of building something large and expected to live a long time with it, though. Anyone who has worked with software for a while should be wary of any solution that claims to be simple.

Anyway, I really enjoyed this but wanted to point out what I like about Go.
"Apps that encourage consumption of tobacco and vape products, illegal drugs, or excessive amounts of alcohol are not permitted on the App Store."

Amphetamine is not an illegal drug in the US. It is available by prescription. Does Apple's statement mean illegal in any jurisdiction in any country? If the app was named something like "methamphetamine" (a different drug, illegal in the US) then Apple might have grounds to remove it under their policy.
Be careful with streaks. There’s another thread on today (about phone addiction) that goes into more depth how streaks can be harmful, but as an anecdote, I had a 500+ day streak on my Apple Watch fitness rings until the watch developed a fault intra day and I didn’t notice til the end of the day, breaking the streak. There’s no way to reset that, or show me new streak information. So I gave up entirely. The pandemic didn’t start for another 3-4 months, by which time I’d given up already.
It's actually a trit[1], but I like your thinking. :-)

I agree and to that list I'd add:

- Performance optimizations (always worth mentioning why you ugly'd up some code for a necessary speedup)

- Kludges where you're working around something in an external library or service
> what the Joint Simulation Environment is really supposed to do

It's for formal verification and validation (V&V).

> why the development of a simulation should hold up the full production

Why shouldn't it hold up production? The program has requirements for formal V&V that they haven't met yet. In theory, you could start production by accepting the risk that you might need to do some rework, but I don't know if that was even an option.

> step through iterations with very quickly

The argument for doing a simulation is to get higher fidelity. It doesn't really make the process any faster on its own. The simulations themselves take a trivial amount of time compared to the preparation and analysis.

> nothing like this has been done before

There's a lot of simulation in aerospace and defense. I don't know exactly how JSE compares in terms of extent and reliance on it, but it's not a completely new idea.

That and dumb password requirements. I could never get my DPM to work more than ~80% of the time, so I had to haul around a supplementary password store anyway. Now I'm on bitwarden, too.

I'd rather have a store that's on another piece of hardware with logging and rate-limiting. Unlike TFA, I'd consider this a strength, not a weakness, but right now the convenience price is extreme.

U2F is good but it's still only a second factor right now and the migration story is abysmal. If they can extend it to serve as a first factor and add a migration story, it would be perfect.

My strategy nearly matches this comment. I'd also set all bill payments to autopay so you avoid any late fees/delinquent accounts which needlessly hurts your credit. I highly encourage you to list out your regular monthly expense categories and write out what that is (e.g. mortgage/utilities/subscriptions), add that all up, and then see what the delta is every month so you know where your discretionary spending is going. Even better is to have a financial goal with a finite number so you know how you are progressing towards it (e.g. emergency fund, vacation fund, retirement, etc).
“Work Life Balance” is missing and item—Career. I don’t think it should be that hard to find the right balance between all three, and you should especially try to have career bleed into work more than life. But if you have any aspirations of getting promoted to a high level and making lots of money (I’m not saying you should have those aspirations), then it’s very likely you’ll need devote at least some of your free time to gaining skills and knowledge that will help you grow in your career.
What I found interesting is

```
Correlation analysis showed no substantial relationship between the mean vitamin D levels and the risk of infection in the younger population (r = −0.16, p = 0.42) or the rate of mortality in the older age group (r = −0.24, p = 0.23).
```

Together with the rest of the issues pointed out here in the comments, I'm sceptical about the value of this study. That said, given that most people should be taking supplements in winter anyways, and that I've seen ZERO warnings about dangers of low-dose supplementation (600 IU/day, not the 3000-6000 some are mentioning here)...
It is a weekly dose. A single weekly dose.
The most insightful way I've ever heard Go described is as a "C fanfic". It's like a bunch of C programmers, writing software for web infrastructure, got together and made a wish-list of things they wanted to be different about C (specifically in the context of writing web infrastructure). And then they made a new language, taking the most direct path toward that wish-list, and inheriting most of C's other traits as a matter of course.

Taken in this light, Go makes a ton of sense. No undefined behavior! Well-defined zero values! Duck typing! Automatic memory management with minimal overhead! Easy-to-use threading primitives and trivial cross-platform builds! A networked-C programmer's dream.

But we've learned a whole lot about language design in the past 40 years, and combining those things we've learned with a loosening of C's constraints, there are much better fundamental design decisions that can be made for a greenfield language. It just seems like Go's designers weren't really interested in questioning a bunch of the ones they were used to.

I found out that xz -1 produces smaller files than gzip -6, faster. That's what we use now.
I also ran into problems that caused me to abandon my DPM after a while. Unique password requirements pet store required storage which added back the sync/dependency on remote storage problem. I also wanted unique logins per site for added privacy/security.
For me both of these requirements are more easily solved with a traditional password manager than a dpm.
Allowing companies to grow to the size of Facebook/Apple etc. is more and more being clearly demonstrated to be a bad thing.

The last time the relative size of US tech giants to EU companies was brought up here, a commentator replied that EU law is designed to prevent companies growing to this kind of outlandish size. I have no idea if that's true or not, but if so, it seems like a prudent approach even if we miss out on brownie points of getting to claim "ours is biggest". As others have pointed out here, the EU is not behind technologically. All we're behind on is company size, and I'm ok with that.

It appears to be full of analogies to other species based on a surface level/pop cultural understanding.

Compare this quote from the link:

> Chimps, our closest living cousins, have human-like brains that can accomplish each of the Five Cs. However, they don’t have social reality. When chimps select a leader, they don’t vote by making marks on smushed bits of dead trees like we do. They follow the alpha male who will threaten or kill any others who challenge him.

with Jane Goodall's study of the chimpanzees, quoting https://news.janegoodall.org/2018/07/10/top-bottom-chimpanze... :

> chimpanzees, like us, have an incredibly complex social structure. And also like humans, that social structure involves friends, enemies, and battles for power. ... The highest-ranking chimpanzee in a group is the alpha-male. ... Take two of the alpha males observed in Gombe, Frodo and Freud, for instance. Though they were brothers, each chimp had a very different leadership style. While Freud maintained control through fostering strong alliances and grooming those he wanted to keep under his command, Frodo relied heavily on aggression and brute strength.

Also, bonobos are as close to humans as chimpanzees, so looking only to chimpanzees as a homology to human behavior is wrong.

> "Songbirds learn their songs from adult tutors."

and from their environment. Here's a bird singing the Nokia ring-tone - https://www.youtube.com/watch?v=cuZKeWi0avw .

And no discussion of whale songs. Quoting https://www.smithsonianmag.com/smart-news/whale-songs-underg... : "humpback whales are highly sophisticated creatures. Their ability to transmit songs, not just within populations, but also between them, “is cultural transmission on a scale comparable to what we find in people,” according to Allen. Having a better understand of what drives cultural and social learning in whales could, therefore, help scientists gain new insight into why these traits have evolved with unparalleled complexity in humans."

Finally, the intro is: "Humans are the only animals who can simply make things up, agree on them as a group, and they become real."

What experiments have been done to test that? Because I've seen any number of statements of the sort "Humans are the only animals who ...", only to find that other animals are, for example, tool users.
A report of some kind could easily indicate more about what happened even if they don’t ‘admit’ anything.

Without that, you’re just making up an assumption based on nothing.
> One existential problem for the genre is that you really need a physical keyboard -- while the awesome "80 Days" can get by with limited choices, anything parser-based really feels crummy on a smartphone or tablet.

Some of the mobile interpreters try to address some of the keyboard issues - with frequently used verbs &c. as composable buttons. Though given the fairly short input of traditional interactive fiction I'm not sure why it should be much more of a problem than say texting (and indeed one of the mobile interpreters even has a text-message type layout for interaction).

I think you’re very in touch with reality of people who are unbanked and have access to free healthcare, and very out of touch with people outside of that group.

No, taking unnecessary risks to do things that aren't legally required for enemies in war is kind of the opposite of the point of being a soldier.

The Constitution doesn't require the government to take any special restraint in war when someone fighting on the other side is a US citizen.

There may be a good argument that the law ought to given the realities of modern war, sure. And that's a debate we should have.
There is still no apple watch face that does not display the time. I filed a radar about this when the watch first launched. I don't like being a clock slave, but do rather like the idea of complications to display data and getting notifications on my wrist.

The amounts of spyware in the app store have caused me to massively scale back my use of apps now, so I almost never wear my apple watch anymore.
I wouldn't call that careless. So far, proposals to extend the for-loop have not passed the cost/benefit test. I think supporting iterators would require something like magic-methods, which so far are not a thing in Zig (language syntax doesn't interact with userland code).

The status quo for iterators is this:

var it = getSomeIterable();
while (it.next()) |item| {
...
}

IMO it's "good but not great" (not great because it adds a var and the variable pollutes the outer scope). But the alternative is a bit of a pandora's box.
