Actually we have those! Cheap migrant workers from eastern Europe make lots of things move here but their choices are limited. We have protections for them at least on paper, and together with low pay that's still better for them than staying home. Most importantly, (I think) they can (with ordinary medical insurance) go to a doctor for an exam or medicine without getting charged thousands of dollars.

The real difference is how the citizens are protected. In Europe, citizen is treated as human regardless of how much money they have. In U.S. this doesn't seem to be so. The money is more important.

They have specifically said, publicly, multiple times, that they've never seen an increase like this before in the history of their business.

Within limits. It doesn't scale infinitely. There is a human aspect involved that doesn't scale instantly.

> Further, a simple ships in X weeks gives them plenty of time to ramp up staff.

Except, again, you are not accounting for lost profits due to increased customer service requests, increased credits to Prime members for not meeting the Prime SLA, increased costs of the warehouses being full of products they can't move because they are constantly moving the new essential products that are coming in, and a whole bunch of other fixed costs that they have not related to their variable costs.
> The result is San Francisco, the most innovative city in a generation, proposing a Office of Emerging Technology to require any technology that uses public space, scooters for example, to get prior permission from the city

That sounds totally reasonable, lest your city become clogged with broken-ass scooters after the n-th scooter startup goes on their "incredible journey" to the stars.

Perhaps if you're going to litter the streets with scooters you should be required to post up cash in escrow for unlittering said scooters if/when you disappear.
I haven't found a problem well suited to either as a solution. Either the performance constraints are too tight for industrial applications or you are in a P2P space and they are both predicated on nodes not being hostile so you can't use them.

This. Before trying to make allocation faster, try to eliminate them first. A lot of code I've seen in higher-level languages, even (or especially?) most C++, seems completely oblivious to the amount of memory manipulation they're doing.

> Why are you afraid of non-scientific ideas?

I’m not sure where you got the idea that people are afraid of non-scientific ideas–I see them discussed all over online everyday by thousands and thousands of people. No one is afraid of them, we just don’t consider them to be science. There should always remain a sharp dividing line between non-scientific/scientific and for good reason.
TFA addresses this: it qualifies by saying learning is good as long as it's useful outside of whatever narrow scope they appear. The real criticism in that section is that hooks (and e.g. gotchas related to things like useEffect, stale closures, etc) are non-transferrable knowledge.

The compiler knows the semantics of malloc. Malloc as it appear in the source code doesn't even need to map 1:1 to calls to the library function, the compiler can remove and coalesce calls at will.

See you are part of that group. If data was presented today that conflicted with your existing views you would try to label and disprove it.

Science must be neutral. Proof of climate stabilism through existing feedback processes may happen or not. We won't know until the data says this. If science is not neutral it becomes religion. Even gravity is just a theory.
+1 for being on board with whatever killed render props and a bunch of HOC's.

Mostly like them, but still not sure the canonical way to write update logic comparing prevProps to current props and running something if it changed where there is more than one dependency though. Need to store prev value in state to compare, or best to ignore the exhaustive deps warning and only run when the prop in question changes? Swear I looked all over and couldn't find a good answer.

You're right. Another issue is the age divide. Younger people: harder hit economically, less so by the virus; older people: harder hit by the virus, less so economically. This can only worsen the class fissure which had already developed along generational lines.

That decreases potential energy, but doesn't all that extreme pressure heavily increase the thermal or kinetic energy towards the center? So while this configuration decreases the potential energy, doesn't it also increase the thermal/kinetic energy? Is it obvious that the decrease of potential energy "wins" over the increase in thermal/kinetic?
Uh, no.

First, the original article is actually about the exact opposite. It says nothing about attacking an opinion based on its merit, it talks about attacking an opinion based on dogma. When I say it's bad science, I'm saying it's bad science because of glaring problems with its methodology; I thought that was obvious (the term "bad science" being fairly common).

Second, I'm talking about the social policy argued for in Ioannidis' opinion piece. Social policy absolutely does not just directly follow the science; they are very different things and absolutely should be discussed separately. I find it a bit absurd to think that science inherently dictates a certain social policy.
They were willing to do some things so long as they didn't slow production. But when their work force starts decreasing, they start losing options.

Wow, I'd never considered that aspect of a heat pump before. But it makes sense -- a heat pump is (conceptually) just a backwards air conditioner, after all; it stands to reason that it'd make the room colder while it's operating.

> Do you realize how much this quarantine is costing us?

Actually, I don't. I've seen a lot of people make the argument that lockdowns and other restrictions are "too expensive", but:

* I have not seen a single serious attempt to model quite how expensive they will be.

* Nor have I seen any attempts to model how expensive alternate approaches would be, e.g. the Swedish model. Quite a few people who propagate it seem to be under the impression that this is implemented with zero economic disruption, but that's definitely not the case.

* And to be truly realistic, the models should consider the capabilities of countries to mitigate economic consequences through fiscal or monetary means. Many countries can currently borrow at very low or even negative interest rates, so they may have considerable leverage there.
Here's the intuition that clicked for me, similar to the above but with a different twist at the end.

Imagine a large flat parking lot, and drive around the parking lot in a circle. Say you have a small pendulum swinging freely, suspended in your car. If you drive the full 360 degrees, the pendulum will appear from the reference frame of the inside of the car to have rotated a full 360 degrees. (Let's say that you are driving fast enough to render the rotation of the earth, the latitude of the parking lot, etc. negligible.)

Whatever fraction of the circle you drive, the pendulum will appear to rotate that same fraction as viewed from inside the car.

Now, here is the fun part. Imagine that you are driving at some fixed latitude on a large sphere. Create a big cone that is just tangent to the sphere on your path. What happens if you drive the entire distance and return to your starting point?

Cut the cone in a vertical straight line starting at its apex, and then flatten out the cone. It will form a flat circle, but with a pie slice removed.

If you had driven the perimeter of this partial circle in the parking lot, you would see that the pendulum only rotated part-way around. The same thing will happen if you drive the full distance around the sphere at the corresponding latitude.
I've, uh, spent significant portions of my life trying to understand just how well we know some particular measured values. And that's not counting the coursework.

So, yeah, I'm going to set myself up for a fall here by saying I've got a pretty decent professional understanding of the topic.

Interesting. :-)

I recently posted a brief document I wrote about a similar structure, immutable AVL trees. I find AVL trees a very nifty structure, I think they don't get as much credits as they deserve: logn (which in practice is about the same as "constant" for most values of n one encounters in practice) insertion, lookup, deletion and even append (for position-based trees, with some assumptions). Incredibly simple implementation. And, if immutable (based on shared memory), allows trivial snapshotting, having multiple "concurrent" trees sharing most of their memory.

Anyhow, it's here: https://github.com/alefore/weblog/blob/master/immutable-avl-...

How do you mean?

To clarify: a "point particle" is an object with no internal structure, that is, it can be fully described by its coordinates wrt time (ignoring relativity for now). This is a concept, a model which explains many phenomena, a model on top of which you can build many theories. It does not, however, explain the conjunction of QM with special relativity.

Also worth noting that false claims need not be malicious to serve as a DOS attack. An army of untrained ‘researchers’ drawing improbable conclusions from randomly combined snippets of scientific papers can generate a huge amount of pseudoscientific ‘sourced-looking’ ideas.

Unfortunately it takes a lot more effort to actually understand a paper then to ‘just throw it out there’.

I get it. I don't like it, but I get it.

Look for a Ryzen 7 laptop with 16GB RAM from Newegg. I mean specifically check 'Newegg' as the only seller. You get two choices starting at $900.

Then uncheck 'Newegg' as the seller and sort by lowest price. You get 24 of the exact same laptop from 24 different sellers with an $80 spread in price. And that's just the cheapest 24 items. There are hundreds more. They start from $650.

For every $900 laptop Newegg sells from its own inventory, they have have to source it, receive it, photograph it, inventory it, ship it, etc. For every $700 laptop from somebody else, they have to...well, do almost nothing. Somebody they don't employ does all the rest. They just keep their web app up and running. Granted, the development of the site is expensive. But it's not expensive per item.

So they can make $50 off every $700 laptop with a minimal expense of pennies per sale. Or they can make $50 off some $900 laptops that cost them pennies + $150 labor per sale.

Alertmanager can run in a clustered mode with `--cluster*` flags. You can read more here[1]. So basically mutliple nodes can run and all Prometheus instances are configured to send all alerts to all AM instances. The alerts are deduplicated at cluster level.

Victoria Metrics right now runs as a single node setup. That works out for now, because as mentioned Prometheus maintains a WAL. So even if the Remote storage is down for sometime, the core functionality of alerts isn't affected. And we've setup alerts on VM health, so if it goes down, we've to act on it and get it back up. Once that happens, all the previous data also is ingested automatically.

This is something that we would surely revisit on at a later point of time, and setup a proper HA on it if needed. :)

Reopening or not is a simple balance between "risk of avoidable deaths" vs. "risk of economic damage". Different people put a different value on each one of those, which makes it a political decision.

Hi everyone, I implemented this card game called Literature: https://en.wikipedia.org/wiki/Literature_(card_game)

I trained a neural net to play against me last summer, but the application was only available through the command line. Now I've built an online version. The bots aren't the ones that I trained over the summer because it was too expensive to run the neural net for free on Heroku.

The web app is built with React in the frontend and Flask in the backend.

The game engine and neural net bots are here: https://github.com/neelsomani/literature

The game server is here: https://github.com/neelsomani/literature-server

Maybe give it a try if you're looking for a new game to play with friends / coworkers!

It will be interesting to see what policy influence Cummings has had. A media outlet earlier had claimed Cummings pushed for no lockdown. So seeing we had a lockdown that would appear to show that he doesn't have much influence. Though, it might be that Cummings opinion on what to do changed as he received more information and he ended up supporting the lockdown. Or it could be that the media misreported the situation.

Well, this is a truism, but it also smacks of special pleading. When readily available data contradicts a line of propaganda or groupthink, you can rationalize why it has many issues and quite possibly be right, but why are you exerting yourself to rationalize in that direction and not the opposite one? Even weak evidence against something should not enhance your confidence in that thing!

If the numbers were really meaningless, it would probably be evident in their clustering or limited range. I noticed the contrary; I didn't post a complete chart because I figured more data would probably result in diminishing returns when urging people to question their beliefs.

Russia, by the way, in the same data set, has about 7.6% more active cases than yesterday. Brazil, 8.4%. Pakistan, 4.8%. So if you hypothesized that all the increases were in the approximate range of +1% to -1%, you would be quite wrong.

Conversely, Germany's figure is down 4.8% and Switzerland is down 6.2%.

It seems as though people for whatever reason fetishize Sweden, among other nordic countries, and I'm increasingly irritated by it. Partly because it reminds me of the current US president and his judgment of different countries as "shitholes" or not. People pretend that they are clearly seeing facts in an unbiased way while doing the opposite.

I love coffee, brings me joy every morning. Feel it's worth it for me.

That said, I drink specialty coffee only, have my own espresso machine, use only high quality freshly roasted beans, etc.

I also don't drink more than 2 cups a day, and rarely drink coffee after noon. Sometimes I do a 3rd one later in the day, but will often go decaf for it.

With the principal cost of the espresso machine and equipment, the maintainance cost, the price of grass fed whole milk and top quality beans, it comes to about 1$ per cup for me. Since I have 1 to 2 cups a day, that averages around 600$ a year I spend on coffee. Which for the pleasure I get from it is well well worth the price in my opinion.
