Quantified effect of vitamin D3/D2 on acute respiratory infections (2017)
Takeaway: If you're vitamin D deficient, taking a D supplement reduces the incidence of acute respiratory infections by 70%.

Here is the study:

The study is a tough read, so here is a video explaining the results:
https://www.youtube.com/watch?v=W5yVGmfivAk

Since coronavirus is a respiratory illness, this could be a tool in slowing it's spread. Especially since most people get their D from UV light, which is in short supply in northern regions right now.
How about "Follow official recommendations" instead ? In France Macron made a show of going to the theatre urging people to live normally (within the new regulations, e.g. no mass gathering above a certain size).

Advising people to stockpile food this early is sure to make the situation even worse.
Where can one obtain raw (anonymized) data on individual cases? Age, sex, location, infection date, severity, outcome, resolution date? Preferably machine readable?

If the loan was fraudulent then it's unjust to enforce it.

Don't want to lose billions of dollars? Don't give out fraudulent loans. Is it tough to avoid incentivising your employees to commit fraud? Aw, you might need to spend some money on combating that, or be less greedy.

I got no skin in US or PRC but I'd like to point out that US screwed up their handling on Covid.19 while China, having the largest outbreak, seems to manage to keep things under control.

You can argue the technique, but you can't argue the result.

Seeing your nickname has "_hk" (hong kong?) I would imagine there's some sentiment against PRC? Let's remove that sentiment for now since virus does not select people based on race nor political ideology.
Ok, I just tried it. Removing every Math. and adding let{cos,sin,PI,min,max,tan,atan2,abs,ceil}=Math; to the top. It worked better then I expected, though it is still 1 byte larger then without. Could potentially be a win in some situations.
> The REPL would be of much more limited use in a language where everything is coupled via shared mutable references.

That would be surprising, since the REPL was developed for Lisp in the 60s, which actually works that way.
Wow very cool startup; wish you guys the best of luck!
But that's less than 10% of the market. The rest doesn't have those problems either, despite having almost entirely proprietary drivers. Therefore it's not the propreitary drivers that are the issue.

How could someone working in a security context in modern times be using non-parameterized queries? I know the answer is along the lines of "because PHP" but I just can't believe it. This really makes me paranoid regarding other security SaaS.

CDC estimates that between 43 million and 89 million cases of 2009 H1N1 occurred between April 2009 and 10 April 2010. The mid-level in this range is about 61 million people infected with 2009 H1N1.

CDC estimates that between about 195,000 and 403,000 H1N1-related hospitalizations occurred between April 2009 and 10 April 2010. The mid-level in this range is about 274,000 2009 H1N1-related hospitalizations.

CDC estimates that between about 8,870 and 18,300 2009 H1N1-related deaths occurred between April 2009 and 10 April 2010. The mid-level in this range is about 12,470 2009 H1N1-related deaths.
Thilde talks about her love for her craft, sense of style and more
Sure, the coup is preordained, but it has been for so long it's starting to smell a bit stale. Gargamel has been hanging around for over a year now. I always suspected he was the sort of loser one appoints when one sort of wants the whole project to fizzle out ignominiously. What's the old saw? Something about "B-level people hire C-level people"? The elected government of Venezuela has been careful to let Guaidó run amok without arresting him or hampering his travel. Now that his erstwhile allies have realized he isn't going to an martyr anytime soon, they're less interested.

CIA themselves are on shakier ground than they used to be. They expected to be ordering Pres. Pence around by now. Now the "grown-up" Democrats have "chosen" Biden (as I predicted in 2017), with whom Trump will play as a cat torments a mouse. Say what you will about his speed habit, at least the Cheeto isn't already sundowning halfway through the afternoon. After he wins this year, Trump will be far more interested in shuttering CIA than in tolerating their further misadventures abroad.

Above, I was actually referring to Hausmann père, not Hausmann fille. The Hausmann (what a traditional Venezuelan name!) family run sort of a low-rent one-stop yes-we'll-take-black-budget-funds shop. Prof. Hausmann is at the K-school, which I guess explains why he didn't actually stop working for Guaidó when he promised Harvard administration he would. He's hoping to land at CFR...
> You do get that a reasonably conservative projection is that within a year most people in the world would have gotten COVID-19? How the heck did Trump do that?

Certainly doesn't help that he fired the US's pandemic response team a few years ago (that pesky "deep state" he's been ranting about). The rest of the world has their own responsibility to some extent but the US usually takes point on these kind of things.

https://www.snopes.com/fact-check/trump-fire-pandemic-team/

He's also had the CDC sandbagging testing for it. He's been claiming coronavirus is a liberal hoax for weeks now, and anyone who contradicts him gets fired.

One of the side effects of that has been the CDC refusing to approve states that developed their own testing (as they are required to get CDC approval). Because they don't want to be seen as arguing that COVID is not a liberal hoax.
Yes, all good conjecture that is likely accurate, but wildly important to not only proceed based on these assumptions and to get definitive proof of the mechanisms
There is almost _NO_ countries are honest regarding the situation.

Iran => not open

China initially messed up

Even countries in S.E. Asia tried to cover up the issue/numbers of infected people.
I remember the drugs company Elan[1] here in Ireland. It got hit bad in the early noughties by accounting issues and other problems, but they had this potentially killer drug called Tysabri and so, as they tanked, there were "smart" investors at every drop buying in and it just kept dropping and kept dropping. Loads of fairly smart people lost a lot of money. Only those who could really follow it all the way to the bottom were ok.

The high was $74 per share. The low was about $2 a share.

I was a victim in 2007 of Wells Fargo’s tactic of re-ordering debit transactions from largest to smallest to maximize overdraft fees. I remember screaming at a bank manager about this practice that he claimed he could do nothing about. I closed my account that day and put my savings into a credit union across the street.
Two problems I find:

1. You'll lose function inline optimizations, and also the branch predictor will get thrashed.

2. Local variables in that function essentially become globals.
You use a shared key I guess.

I had a look how keybase does it [1] but they don't say in that blog post. But in their post about encyrpted group chat and chat bots they do say there is a shred key for the group caht.

> what changed?

Complexity and integration requirements. Tanks 70 years ago were not as complex as our current heavy armor by several orders of magnitude.

=== EDIT ===

To clarify: the complexity arises from electronics and electro-mechanical assemblies, the chemistry/metallurgy/materials science from armor/chassis, engine complexity (M1 has a jet turbine), and so on. We have a depth of advancement that is as complex at the knowledge end as it is at the application end.
Easy interface, easy signup, and able to trade derivatives without a mountain of paperwork. I don't use it for the family investment company, but I get why people just starting out do.
Windows runs on ARM, as does Linux.

I'm sure if apple switched entirely to ARM, lots of other software would switch too, and we might even eventually see the end of the x86 era.
What do you mean by "throttle"?

Edit: What actions can we take to reduce the spread of this misinformation effectively?
It's an old open source project that isn't really actively developed. But also: I'd resist the inclination to believe that security product companies are especially good at building secure software.
Moving personal computing to ARM is going to enslave us, the end users. The temptation for the OEMs to lock everything down and integrate all components into non-extensible hardware is too strong.

I'm not arguing that Clojure is as widely used as Java or Python, which are two most popular languages in the world. I'm saying that it's a ridiculous bar to set for calling something mainstream.

However, there are some other metrics we can look at. For example, if we look at downloads for popular libraries, we can see that Ring's been downloaded 9,058,741 times, and obviously there are repeat downloads for the same users, but even accounting for that it indicates a much bigger user base than you're suggesting. https://clojars.org/ring/ring-core

Other data points would be commercial tooling like Cursive and commercial funding for projects with organizations like Clojurists Together indicates that there is a critical mass of commercial users who are willing to fund projects

Finally, Clojure usage is growing for new projects both in enterprise and government sectors in countries like Finalnd

This is a very different picture from a tiny isolated community of a few thousand developers that you seem to be painting.
Also, road wear is a function of friction as well as pressure. Friction is increased with additional tires.
Depends how seamlessly they can get devs to re-compile. ARM having to emulate x86 would be definitely slower.

There is no reason to believe the per-watt performance of actual ARM code won't outperform equivalent x86 chips. i.e. an A(x) Macbook Air replacement could easily outperform the Intel variant at the same power envelope, based on the observed performance of the iPad pro my wife uses.
"75,000 lbs" .... whoa.

> Is what we are seeing now primarily a consequence of of COVID-19 or not?

"is the 2008 crisis primarily a consequence of mortgages or not?"

In the grand scheme of things, no, it's a consequence of a bubbled economy that has been goosed with tax cuts, extremely low interest rates, and deregulation for too long and is overdue for a correction. The proximate cause is Covid but it just was the spark that lit the fire, there was lots of fuel building up.

https://en.wikipedia.org/wiki/Necessity_and_sufficiency

This is why you don't cut tax rates and keep interest rates super low when the economy is already roaring. Now we're out of options for dealing with a real financial crisis.

Trump of course understands none of this since he's a narcissistic con man who just understands "tax cuts = economy more better!". Insofar as he can be said to understand anything - he's not a man that can be described as intellectually curious.
Does this really change anything compared to every other POS system that you swipe your credit card into and get your receipt sent to your email?
Network effects are pretty huge for these things. A country could e.g. spin up its own Mastodon instance, but good luck getting people to use it. The country-based LinkedIn might work, since that's inherently local, and lots of countries have some kind of state job advert service tied to their unemployment benefits. It would be a bit nasty to make "you have to be on BritLinkedIn to recieve unemployment benefit" a condition but I can absolutely see someone coming up with that idea.

At the other end of hyperlocal, I've always been surprised that Edinburgh has its own dominant property market website (ESPC).

That's still PII; you need to aggregate to actually anonymize.
The problem isn't even that. There's no global account catalog you could search. Thus, you have no way of knowing who of the people you know is on there already. Asking everyone if they know about Mastodon and which instance they're on isn't the answer. I have an idea about making a DHT out of instance servers, but at this point it's purely theoretical. If it does work though, you'll be able to easily import your existing friend lists from centralized services. Could use either their APIs or — better — the GDPR-mandated export feature.

What's even worse is that once Amazon collects enough data they'll be able to compete more effectively with these retailers and eventually kill them.
Seeing a few negative comments here; I think these are short-sighted in the extreme.

Labor is a major cost for retail; anything that massively reduces labor costs is going to be hugely game changing. Combined with amazon promises that it takes only a few weeks to integrate (seriously??) if this works at all, this is going to be a super fast growth group at Amazon.

For reference think back to how many stories you’ve read about say managers short changing employees a few minutes at the end of work shifts.

This really could change retail permanently; the only question is if it works.
18 hrs/wk of 1-1s incl. w/ reports, peers, and my own manager. 2 hrs/wk staff/leadership mtgs. 4-6 hrs/wk project mtgs. 4-6 hrs/wk ad-hoc mtgs.

That makes... ~30 hrs/wk of meetings. Yup, that just about matches my calendar.

Longest: the 1.5 hrs my manager and I have blocked off for our 1-1s. It doesn't always run that long, but we also often run out of time.

Needles to say, this applies only to vitamin D deficiency. Taking extra large amounts when you don't have deficiency is completely different issue.

Pre-powerpoint app presentations were popular back in the days. In the 80s I recall there was a huge industry of educational presentations for 8-bit Commodore and Atari machines. Some good, some bad, and some very bad. There were a few that were interactive and "hyperlinked". In particular I learned programming Atari ANTIC display lists and players & missiles with one that allowed you to modify things in an editor/debugger in realtime so you could immediately see the changes in the graphics, and also checked your correct responses at the end in the self-evaluation section. Pretty awesome. I wonder if they used an external software to program that or they just did everything themselves, as it was usually done then.

I just downloaded DosBox, installed Win3.1 and the software. I am having a blast down memory lane. It's impressive how your brain can retrieve memories so well with only minimal hints after more than 20 years... the persistence of memory!
United Kingdom to introduce Security Labelling on connected devices
That was a pretty weak explanation, only a single sentence referencing the actual technical issue with some stuff about it causing some knock-on outages elsewhere:

> We now understand the cause of the outage was stress on our infrastructure—which struggled with unprecedented load. That in turn led to a “thundering herd” effect—triggering a failure of our DNS system.

I was planning to wait for the post-mortem because I dislike speculating and I'm not personally invested here, so I prefer to wait. I'm curious when they'll release the full one because it's going to be one of the most interesting ones in a while, given the large scale of the failure and potential implications... (ignoring today's outage)
Long Live the Wonderful and Ridiculous Electronic Signature Pad
We've had worms for composting for about six years now.

To keep them happy, you just need enough paper / cardboard to regulate excess moisture. Plus a bunch of drain holes.

If the environment you've created isn't something a plant would want to live in, a worm isn't going to like it either.

Our worms have survived a tremendous amount of neglect.

Sadly, my wife had our worm bins sitting on the driveway on garbage day last fall and the garbage man mistook them for garbage. Trying to rebuild our colony from ones we dug up from the garden where we had deposited them earlier in the year. It's been slow going and we'd probably be just as well off to order a new batch.

Fair crit! Running off of few hours of sleep last night (spent way too long defending k in this thread; need to set sensible noprocrast settings or get some flavor of self-control); accuracy is impaired.

One other question that I haven't seen addressed is, what about GPUs?

Apple makes a GPU for the iPads that seems to compare very favorably to AMD's laptop offerings. I imagine anything written in Metal should "just work," but what about OpenGL? It's now deprecated in MacOS but still sort of on life support, and it seems a little premature to just cut the cord on that.

Or could AMD GPUs work on ARM? That also seems like kind of a heavy lift…
Somewhat related: Initially, I thought this was about the walk out protests happening (over politics and environmental concerns) at some big tech companies. I had some pretty big questions on why Amazon wanted a piece of that market.
In terms of cost-convenience trade-off, can someone tell me how is this better for a store when compared to self-checkout counters or scan-as-you-go apps (as suggested below) ?

I use these frequently at Walmart and Sams without any problems. Rarely have to deal with an actual checkout person unless I have to get a gift card.

IMO you can get very far simply addressing annoying latency and UX issues with self checkout counters.

Edit: There is also the advantage of seeing what you're exactly being billed for
It might be slow for larger retailers, but I could imagine small independent "hipster" type shops opening up using this (people with the same mentality as the "no cash" bars/restaurants)
What great timing. This is being introduced just as the entire global public becomes nervous about entering enclosed rooms populated with strangers.
No thanks. I don’t stay at home worrying about tractor-trailers or terrorists, either.
It's a little funny comparing a language with another language+plus-its-entire-ecosystem, but k fares remarkably well I think.

Counter could be #:'=: (count each group)

c:#:'=:

Values would just be dot.

Counter[x]&Counter[y] is a bit tricky to write, because while the documentation says set intersection, what they really mean is the set intersection of the keys with the lower of the values.

This is entirely clear in k; First, understand I have a common "inter" function that I use frequently (it's actually called "inter" in q):

n:{x@&x in y}

and from there, I can implement this weird function with this:

i:{(?,/n[!x;!y])#x&y}

I've never needed this particular function, but I can read out the characters: distinct raze intersection of keys-of-x and keys-of-y, taking [from] x and y. It sounds very similar to definition of the function I gave above (if you realise the relationship between "and" and "lower of the values"), and this was painless to write.

most_common could be: {k!x k:y#>x} but if I'm going to want the sort (in q) I might write y#desc x which is shorter. In this I can save a character by reversing the arguments:

m:{k!y k:x#>y}

so our finished program (once we've defined all our "helper functions" in a module) is:

m[3] i . c'(x;y)

So we're looking at 13 lexemes, versus 19 - a minor victory unless you count the cost of:

from collections import Counter

and start counting by bytes! But there's more value here:

All of these functions operate on data, so whether the data lives on the disk or not makes no difference to k.

That's really powerful.

In Python I need more code to get it off the disk if that's where it is.

I also may have to deal with the possibility the data might "live" in another object (like numpy) so either I trust in the (in)efficiency of the numpy-to-list conversion, or I might have to do something else (in which case really understanding how Counter[a]&Counter[b] works will be important!).

I might also struggle to make this work on a big data set in python, but k will do just fine even if you give it millions of values to eat.

These things are valuable. Now if you're interested in playing games, let's try something hard:

"j"$`:x?`f

It creates (if necessary) a new enumeration in a file called "x" which persists the unique index of f, so:

q)"j"$`:x?`f
0
q)"j"$`:x?`g
1
q)"j"$`:x?`h
2
q)"j"$`:x?`f
0

How would you do this in Python?
