Rounding up .5 is considered proper form.

Sure, they'll last shorter, but at least they will work.

Besides, couldn't they keep it at a stable -20 °C?

> ICs frequently passing zero degrees, which aren't packaged in completely water impermeable packaging like ceramics or metal are also having issues

Issues with condensation?

Well, that makes sense. So why can't they be packaged in metal or ceramics?

What about tax havens and such? As you said, if I put some money into the stock market,

* my broker/bank takes some. If my broker is a public company, some of the money goes to pay operational expenses, and some of the money goes to their shareholders as dividends.

* the stocks I bought go up slightly. They get cheaper capital, and their owners get an unrealized gain.

Schematically, we can assume all bank employees put all their money into the stock market. So the end result is that the benefits accrue to shareholders of public companies, regardless of which stock you buy.

But if money never exits the financial system to go back into the real economy, none of this matters. If a large chunk of the public stock market is held by buy-and-hold investors who just never liquidate their investments nor pay tax, this money will never come to benefit ordinary folks.

Some of it will, by way of pension funds and whatnot. But it's worse than spending it on normal consumption, as I see it.

Anything is better than nothing, isn't it?

Savings rate goes up with income. On a percentage basis, the 10% are going to be spending more money at restaurants, shops, etc. This is, arguably, preferable to the 1% investing it in the stock market.

heartbeats··on Handling 350k Requests for $3 using Lambda
I don't understand why you're getting downvoted. If you're serving simple content, the bottleneck is going to be the network card or disk, every time. In this case, you have static content: a well-written web server (not nginx, but mongoose or similar) can easily handle enough requests to saturate a gigabit uplink on a first gen Raspberry Pi.

Not that it has a gigabit uplink. But handling 100k req/s is trivial for a well-written server.

I am a layman here, but couldn't they just use more aggressive cooling on the outside? If the exterior were cooled to -20°C, wouldn't that keep the interior from getting too hot as well?
heartbeats··on Are ad blockers doomed or have we already won? A history lesson
> Then ad blocking (and other customization) will be limited to "the analog hole" - trying to image detect or OCR things.

That doesn't seem too hard to pull off. You're not trying to find objects in an image, you're trying to find near-exact matches in a digitally rendered page.

Gee, I wonder why.

heartbeats··on Mapping Coronavirus, Responsibly
It seems like the heat map can be useful there, as long as you divide it by population count.
heartbeats··on Mapping Coronavirus, Responsibly
>therefore the population ought to have some kind of exponent attached to it, like particles bouncing against one another in a container.

Population squared? That gives you the number of potential connections.

heartbeats··on Mapping Coronavirus, Responsibly
>We’re mapping a human health tragedy that may get way worse before it subsides. Do we really want the map to be screaming bright red? Red [...] can connotates [sic] danger, and death, which is still statistically extremely rare for coronavirus.

This really seems like a case of "it's not a bug, it's a feature". It may be rare (so far, anyway), but few would argue "danger and death" is an inaccurate characterization.

You do realize this is the same country which made it punishable by up to 10 years' prison to have a specific terrorist's manifesto on your computer?

Snark aside, that is a good point. Erlang is a nice language and it was developed as a pretty short-term project to fill a specific need. In fact, you might even argue it is a nice language because it was developed as a pretty short-term project to fill a specific need.

How is that a good thing though? American police are not very popular, to put it bluntly. Even among the Americans I know who support their efforts, they still do not have any affinity towards individual police officers.

Compare this to the situation in Europe and Asia (or at least the civilized parts like Japan), where it's perfectly acceptable and normal to ask a policeman for directions. And where their role is indeed to protect and serve people (not property).

"Police have the role of protecting and serving people" really does not feel like such a controversial viewpoint to me.

With how some people use smartphones, you really do start to wonder. Just try to get someone to leave their smartphone at home when they're going outside - they look at you like you're crazy.

Freedom isn't free. I think people have just ought to realize that. People have this idea that free countries are more efficient, which is probably true in the long run, but it's a cop-out to just call it a day there.

Once I was in Belarus. It's a heavily authoritarian country, make no mistake. When they had protests against their rigged elections, they traced the phones of everyone who went, then brought them in for questioning and asked them what they were doing there. The president later said: "We have rigged the latest election. 93.5 per cent have voted for Lukashenko. But they say it is not a European outcome. We have made it 86 per cent."

But it does work. I was at a restaurant there. Some girls are chatting, and they walk away to go get something, and just leave their bags there unattended. Why? Because it's an authoritarian country - people aren't going to steal stuff there.

This was in the capital of one of the poorest countries in Europe, but it was still one of the safest places I've ever been.

EDIT: I don't mean to praise authoritarian countries, on the contrary. We should support human rights even if it is less efficient, because the object of governance is not to strip people of their freedoms for pennies on the dollar.

heartbeats··on Loading NumPy arrays from disk: mmap() vs. Zarr/HDF5
> The data has to be on the filesystem. You can’t load data from a blob store like AWS S3.

You sure about this? You can mount S3 locally, and the filesystem should be transparent to the kernel.

heartbeats··on Tokyo Olympics “looking at a cancellation” if coronavirus not contained
Yeah, but that goes against the rules. In civilized conversation, your only choice is to use incomprehensible euphemisms. He did a really great job - there is no kind of dog-whistle or outright strange language ("the urban crowd"). Perhaps he could have wrote 'normal french', but that's honestly a minor gripe.

You really have no choice but to phrase yourself in a way that's only recognizable to the in-crowd. Even here, with the polite expression, he is catching flak.

Personally, I don't discuss politics in real life anymore. Risks are too great. Just the Internet, where on some forums (not this one), you can be honest about what you think.

heartbeats··on Tokyo Olympics “looking at a cancellation” if coronavirus not contained
What's he supposed to do? He went out of his way to put it in the polite way for you. Unless you want to go into complete incomprehensibility, it's a "rock and a hard place" situation.

Yeah, but if 2% of all the Chinese die that's going to mess their economy up real good. Considering the whole thing is a house of cards, I'm bullish on the coronavirus.

> Greece is imposing fines on those who conduct a large enough ratio of their transactions in cash

That's extremely unethical. But more importantly, doesn't it cause huge perverse incentives?

Correct me if I'm wrong, but the way this works is that you pretend the cash transactions didn't happen, and write the inventory off as lost or whatever. Or you buy the inventory for cash as well.

So if you have 50% cash and 50% card, you might report only 50% of the cash and reduce your reported gross income by 25%.

In other words, the legitimate but cash-eager businesses will have to pay fines. The frauds can boast about their 100% cashless ratio and pay no taxes as well as no fines.

So how do you do this then? My circle of friends obviously consists of people similar to me, I would have to go two or three hops to find any women.

To visit the Philippines seems a bit drastic.

Both of you are describing the same concept :)

> In economics, insurance, and risk management, adverse selection is a market situation where buyers and sellers have different information, so that a participant might participate selectively in trades which benefit them the most, at the expense of the other trader. A textbook example is Akerlof's market for lemons.

> The party without the information is worried about an unfair ("rigged") trade, which occurs when the party who has all the information uses it to their advantage. The fear of rigged trade can prompt the worried party to withdraw from the interaction, diminishing the volume of trade in the market. This can cause a knock-on effect and the unraveling of the market. An additional implication of this potential for market collapse is that it can work as an entry deterrence that leads to high margins without additional entry.

> Buyers sometimes have better information about how much benefit they can extract from a service. For example, an all-you-can-eat buffet restaurant that sets one price for all customers risks being adversely selected against by high appetite and hence, the least profitable customers. The restaurant has no way of knowing whether a given customer has a high or low appetite. The customer is the only one who knows if they have a high or low appetite. In this case the high appetite customers are more likely to use the information they have and to go to the restaurant.

That sounds like a damning indictment of STEM.
heartbeats··on Iran lawmaker says 50 dead from coronavirus in city of Qom
Right, but you are not the U.S. government. When I think about it, the statement could be expanded. If we are strictly dealing with geopolitical power, we can replace "Iranians" with "non-Americans" and it will still be correct: a world in which all non-Americans are dead will be a world of great geopolitical power for the Americans.
heartbeats··on The general value of typed functional programming lies in leaving no edge cases
If you try to use it val directly, it fails. You must unpack it first.

To do something like x.get() in Scala when x is empty is a runtime error, not a compile-time error.

A zero-sum game is a zero-sum game is a zero-sum game. If it spreads, it's likely to do so to other MidEast countries and Africa. And while, in an ideal world, the US would like to be friends with everybody, they are cozying up to China. If that happens, the old adage goes: We had to destroy the village in order to save it.
