The even perfect numbers all have the formula

2^(p - 1)(2^p - 1)

for some prime `p`. In code that's

((1 << p) - 1) << (p - 1)

for `p` = 2, 3, 5, 7 and 13, which is why you're seeing that interesting pattern of bits.

(There are no odd perfect numbers in the range under consideration.)

Built a simple `PyMC3` model based on your comment: https://github.com/zachwill/covid-19
I think that if we truly want to keep people safe, we should stop making assumptions about how low the risk is, etc. All it takes is that you are in that low percent and that's it. I am not saying we should start panicking, however, leveraging modern tools (remote work) whenever possible is key to reduce the risk even further. It's just prevention.
Babylon 5 had technomages. Similar, if a little less sinister.
I think there is a chance that's true. But there's also a decent chance it is still containable. All depends on whether China's numbers are accurate.
This isn't surprising. American cities have a significant number of undocumented people residing in them and the US government has done a great deal to discourage those people from cooperating with government authority. And since the disease doesn't have any obvious indicators to distinguish it from a flu in the early stages, people will not risk deportation or separation of their family over the possibility that they're bad cough might be COV. Any attempts to track things like disease pathology through people who don't trust the government is going to be difficult.

The virus isn’t understood well enough yet. It’s not your standard virus. For example animals are carriers and can be infected ie. pets. Let me answer your question with a question - do you want to get aids?

As an example, Not to stigmatize aids patients. Were also learning that recovering from virus does not mean immunity. Several cases of reinfection already present. Why put yourself at risk if it’s not well understood.
Enable if is fine if you have mutually exclusive choices (although the way it work is pure magic), but it quickly becomes very complex for overlapping cases as you have to somehow hack the partial ordering in. A chain of constexpr if is significantly easier to write and understand.

The right solution are of course concepts.
Good points* with which I agree. None of the stuff I do is 'cloak and dagger' so leakage of that info doesn't matter. My only aim is to minimize the data Google siphons from one's phone—information that I believe has been unfairly obtained by Google because of its market monopoly and the fact that it's effectively usurped the phone network for its own benefit.

I am in no doubt that the moment a SIM is inserted into a phone and it's switched on that the activities you've outlined happen—and all that gear you've mentioned then "has your everything in the database". For my purposes, that all that gear has soaked up info is essentially irrelevant (as it's going to happen anyway the first time one makes a call).

If I was being rigorous (or up to some nefarious mischief) and did not want any of that data to leak (at least until I was ready) then I'd disconnect the phone's antenna
and/or conduct the work within a Faraday cage to stop the the radiation. Also, there are other details and steps I'd take but I'll deliberately refrain from mentioning them.

> because mixed speed traffic with cars just doesn't work when cars are going faster

Why doesn't it work? I frequently commute by bicycle by traveling at speeds ranging from 10 to 40 km/h (averaging around 18 to 20 km/h) amongst motorized traffic moving at 25 to 80 km/h without any issues. I do something very similar on interstate highways (motorways) where I drive 110 to 130 km/h amongst tractor-trailers moving at 60 to 100 km/h.

> unprotected bike lanes are just a bandaid solution to that problem.

Bike lanes don't solve anything and they cause problems for cyclists at intersections because they direct cyclists to pass traffic on the wrong side when traffic plans to turn.

Hmm, I can't think of a way to use the mathematical structure of those numbers to speed up checking.

However, the reason I said AVX is because it can be used for checking equality of 5 (well, 8) numbers simultaneously. This solution requires AVX2 and is probably faster than the optimized reference code.

// Copy x to all 8 elements.
__m256i a = _mm256_set1_epi32(x);
// Duplicate 6 because we need to fill all 8 elements.
__m256i b = _mm256_set_epi32(6, 28, 496, 8128, 33550336, 6, 6, 6);
// Check for element-wise equality.
__m256i c = _mm256_cmpeq_epi32(a, b);
// Check if any bytes are nonzero.
return _mm256_movemask_epi8(c) != 0;

I listed as an aesthetic difference. Maybe some people like induction plates. My experience with them (in rentals, hotels and my present apartment) is they deliver very little heat, slowly. If there is some "not underpowered" variety, they're not used very often, and coil stoves work better. They also scratch easily; adding planned obsolescence to your stove experience. There's nothing scratchable in coils or gas stoves; and I'm pretty sure that's why the latter two have gone away.
> this corporate disdain for quality of work environment

You may find the term "managerialism" handy. It's the belief that managers and execs are the central story of a company, that everything must flow through them, especially key decisions. And of course, that as the special people, they deserve outsized rewards. It's the dominant philosophy of US business, and although it seems eternal to us, it was invented in the 1950s and 1960s, along with the MBA that became a vital qualifier to join the managerial class. And it is definitely a class system; note who flies in "business class", for example.

It took me a long time to be able to see it, but once I did I see it all over the place. It was sort of the same struggle when I learned functional programming: I had never really thought about the rest of programming, its philosophy and value system. I was soaking in it, so I didn't need to.

The book that got me going was "Confronting Managerialism", but I'm sure there's a fair bit more out there these days: https://www.amazon.com/Confronting-Managerialism-Business-Ec...

But these are public photos offered by facebook under that license.

Anyone visiting the profile will have a copy of said public photo in there cache. That in itself doesn't trigger a copyright act because the photo is licensed for that act.

Reusing the image would trigger copyright protections as the licease granted to facebook doesn't cover that. It would be the same as downloading a trial program with images. You can use them in the game, you can make calculations on those images (they are this big, they are classifed as tree, face, etc) but you can't include them in your game.
Damn I hope I never work under someone who considers their employees to be toddlers.
> But you can totally ride faster than walking on footpaths provided they're big enough,

That really depends on how many pedestrians are using the foot path. Plus, why use the footpath when I can use the road and ride at commute speed? Similarly, when I drive my car, I prefer taking the highway/motorway since I can drive faster than I can using surface streets.
I’d benchmark that before being sure.
It's interesting because the experience between Aldi and Trader Joe's is very different. I personally find Aldi to be a depressing experience, and I don't know why people say such great things about it, whereas Trader Joe's is an excellent example of success created in large part by treating employees well. The culture of Trader Joe's doesn't seem to have been incorporated into Aldi in any way. Then again, maybe the Aldi locations in California are subpar compared to elsewhere?

>>Having information and services a click away has begun to feel almost like a burden. Everything has to happen instantly now. This has been a negative from a psychological perspective for me

I feel you. I recently upgraded to a dumbphone (~1 month), no apps. Basically, I can do calls, even texting is too irritating. Yeah some stuff is harder, but the psychological burden has lessened to a marked degree.

I'd love to hear other ways people have figured out how to reduce the constant low-level anxiety in our daily lives.

It's fun seeing the comments here and the two sides of this. For me, being a team of 1, I pay for gsuite, Streak, Calendly, Docsend, Hellosign, and github. When I add a few staff members, I'll happily pay for Slack and Notion.

Yes, it's a lot of subscriptions for a tiny team, but if the combination of all of those (or heck even one of them) saves me 2-3 hours per month, it's worth it. If I close one deal, it's worth it. But really I love that I can set up a few zaps on Zapier and write a few API calls and it frees me up to spend my time thinking about higher-value things.

I get vendor fatigue and I understand that many of these tools get really expensive as you scale, but I'm pretty thrilled to live in a time when I can find tools that I can make talk to each other for a relatively low monthly cost.
I worked in hospital IT for a little while and I wouldn't say this is the rule, but man you really nailed the exception hahaha.
Which is why drivers typically change lanes to pass. Unfortunately, most bike paths are rather narrow and preclude that possibility when you get stuck behind a slower cyclist or pedestrian.
>What is it in us that longs to do that?

It is animism, the belief that everything is alive, active and imbued with spirit and it is very natural. It arises because we perceive things only indirectly, via our mental representations of them. We (our minds) live in an inner, virtual, world. It matches the outer world only partially. The match is limited by matters such as how rational we are, how much we know, how much our culture knows, what our misconceptions and mistakes are, and so on. All very much in line with Karl Popper's epistemology.

Our mental representations are alive in the sense that they are labile and interconnected in all sorts of ways that make up our worldview. Creative geniuses don't consider their tools dispassionately. They literally relate to them, e.g. a certain equation might be like an old friend.

The problem for the animists is that just because things (trees, rocks, equations) are connected in our minds does not imply they are connected in the real, external universe. There aren't spirits 'out there'. If there is a spirit, it's 'in here' working behind the scene. It's the operation of our own brain. So primitive cultures had a very limited knowledge of how the outer physical world worked outside of necessary activities such as hunting. Scientific knowledge came later.

Materialists, on the other hand, i.e. most of us nowadays, assume that they perceive external physical reality directly. They forget they had to spend months just learning to see things when they were babies. (Or that this process was more about sorting out what was what than about building a telescope.) They assume that objects are are unconnected, like atoms in a void. This is of course true on the wider physical level but merely self-fulfilling in the inner world. Thus their mental representations of things (not us) remain relatively dormant. They never hear the 'wind in the willows' and never realise their full creative power.
JMS obviously wanted to sneak in some high fantasy into his SF. The mystical themes (an epic battle between beings of light versus beings of shadow, resurrection, reincarnation, immortality, fate versus free will) names like Lorien, Morden, Zha Ha Dum, technomages (wizards - the "techno" part was just a thinly veiled contrivance, they were obviously just wizards) and the like are all basically fantasy tropes.

The Minbari were space elves and I defy you to prove me wrong.

And then you watch Crusade and realize it's literally an RPG party doing quests in a spaceship.
That last statement is not really a true. There are a great many things which do not kill you and leave long term negative impacts. There are many diseases that your body can fight off but long lasting damage remains and that damage can even be passed on to offspring.

While people are generally resilient it's a bad idea to knowingly get harmful diseases due to the long term impacts. Your example of Chicken pox parties are regarded as a bad idea universally by the medical field, it would be smarter to get the vaccine. Mother's who want their children to get it are miseducated on the subject.

While there will always be something new, modern hygiene practices, when followed, greatly hinder the spread of things until proper treatments and vaccines are developed.

One of things that I would like to see happen is the use of natural antibacterial and antiviral metals used for commonly touched items. We know that copper containing alloys do this. I'm sure with study there could be other cheaper ones found which would be an easy augment to standard hygiene.
>He blamed presidential candidate Mike Bloomberg and Democratic campaign donor George Soros, both of Jewish descent, using the term “elites.”

What's the difference between "elites" which is used by rightwingers and "the 1% of 1%" which is used by leftwingers? I would change my mind in the face of evidence but I'm not sure I follow this point about "veiled antisemitism."
Fast.ai really democratizes the bleeding edge research for the masses, though, that’s why it’s popular among outcasts and outsiders. In general, I would be more wary of people working within closed environments and organizations than people making all they do public and open to review.
At least in China, somebody knew the ground truth.

As much as I criticised China's initial response, their eventual containment has proved highly effective.

The US (and numerous other countries) are point-by-point repeating China's initial failures.

This will delay control by days. Growth is presently doubling every 3 or so days, increasing by an order of magnitude every week. Delays will increase consequences directly proportionate to those rates, both infections and deaths.

As it is, if Rest-of-World (RoW) response is where China was ~22 January, we can expect to see 100x present cases (~2 orders of magnitude) and ~500x present deaths (~2.5x OOM). Very roughly.
Aldi in Europe is just another budget supermarket, but carry a variety of goods that you can't get elsewhere, certain cosmetics and German bread. It's loved by many for this reason. Otherwise, I also find Trader Joe's much more satisfying. If it came to Europe I wouldn't protest!
Why should this have anything to do with people without documentation?

People in general just don't seem to be taking this very seriously, and I've seen plenty of people who cough up a storm on the subway, in libraries, and other places where people gather. People in general just aren't very considerate and tend not to self-isolate.

One doesn't have to lack documentation or fear going to the doctor to act that way.

Also, there just hasn't been a lot of testing for COVID-19 done in the US. So even if you did go to the doctor odds are that you wouldn't get tested for this disease.
The Golang piece is definitely subpar, it was quickly thrown together in half a day, didn't expect it to be spread so widely haha.

For other articles there's usually a few days of research, and 1.5 days of writing and editing, then a lot of touch-ups in the following weeks/months responding to feedback.

Thanks for the more detailed criticism though - I agree with the general sentiment, and haven't solved the navigation problem yet!

> food,

It's still nutrition and food insecurity are still an issue. Calories are plenty but large number of poor still suffer from malnutrition because healthy food is very expensive and neighborhood deprivation creates food deserts.

> Even people with mobile homes often own their homes

Mobile home business in US are huge predatory business model that keeps people poor. Private equity companies buy and own many mobile home parks and the loans for mobile homes are expensive, plus the homes are bad investment. They lose value just like a car. John Oliver made an episode about this.

>It's something else,

Relative poverty is real poverty. It goes against all evidence to claim that only absolute poverty is real poverty and only thing that should be addressed. Just being poor hurts even cognitive functionality and causes stress. People who have less options, less time to make decisions, are forced to long term of short decisions that are non-optimal.

There has been a great natural experiment testing the culture theory and direction of causal link.

In the 80's when drug epidemic ravaged black neighborhoods there were two theories. One theory was that poverty causes desperation, destroys culture and brings drugs and destroys neighborhoods. Another theory was that culture causes poverty and drug use and creates bad neighborhoods.

Opioid crisis provides great second data point and natural experience. It turns out that when poverty and financial insecurity hits white middle class neighborhoods, they are just as susceptible to drug epidemics, destruction of cultural values as black neighborhoods.

It seems that relative poverty and decreasing options and loss of hope creates culture and behavior more than other way around.
I'm old, so I remember the media consolidation of the 80s. FCC rules about ownership of newspapers and radio/TV stations, and number of stations in a given market went away. Soon after, the fairness doctrine did too. This lead directly to conservative radio. All objections got waved off and laughed away: the free market has spoken.

Now we have a situation where the same conservatives are getting cut out, and it's no longer the free market speaking, and the government is supposed to step in to protect and affirm a particular set of opinions.

I don't think this is a particularly consistent viewpoint, and it makes me wonder how much the free market had to do with ditching the fairness doctrine and the less conservative radio and TV voices.
