Credit cards allow for disputes when there are problems with the transaction (fraudulent seller, not honoring terms, not providing services, etc). It does not cover you mistakenly buying what you don't need.

Filing a dispute when you knowingly made a mistake is a bad move, and your bank will quickly figure this out when AWS provides the billing statement, API logs and signed TOS. You're going to have a very tough time if you try to litigate this in court.

Debts (or at least payment plans) can be negotiated. Disputing to weasel out of them will only make things worse. A little communication can go a long way.
Linuxcnc on a raspberry pi 4 is fast enough to run the motion-control loop of linuxcnc with 1kHz, worst case latency is below 100us with current rt-preempt kernels.

Generation of stepper signals or interfacing with servo amplifiers and encoders is best left to an external microcontroller of FPGA card, connected either via SPI or ethernet.
South Korea was no exception. The country also underestimated the virus in the beginning. The pro-commie China president Moon of South Korea declared a premature victory and donated 2M face masks to China, just before a major outbreak caused by a right-wing cult in Daegu where Patient #31 was a member, only to find the country in masks shortage.

South Korea was however better prepared only because they had another coronavirus called MERS (Middle East Respiratory Symdrome) not too long (in 2015). The MERS outbreak wasn't as fatal (only 180+ cases with 30+ death), but it had significant impact on their economy and exposed their weaknesses. So they learned quickly and spent the last five years reforming regulation, logistic/supply-chain, and public policy, and preparedfor next public health crisis.

South Korea has not lowered their standard, but, unlike its collectivists neighbors like Taiwan, China, not everyone is onboard with the gov't's effort, especially among some right-wing Christian religious groups, and they now average 100 new cases per day -- and most of them come from either church or hospital.
One thing on my mind with this is how different the cause is. In many cases, like the great recession, I'd say there was an internal structural, systemic cause for the collapse. But in this case, it's a virus, coupled with top down government lockdowns. That doesn't mean it doesn't economically matter, but wouldn't the recovery process be different, maybe faster?

This is just me thinking out loud; I also expect this line of reasoning could be really misguided. It's not like there aren't any structural problems in the world at the moment.

There are many good answers here already. As long as you understand that, in PostgreSQL you 1) connect to a single database; 2) you can only query within a single database (normally); and 3) multiple PostgreSQL schemas can exist in a database and that you may query across them, you understand the functionality well enough.

So I have a few practices related to PostgreSQL schemas that I like to employ when I'm designing a PostgreSQL database. I tend to work in enterprise business systems with larger database structures than many here I think, so to be sure, what I typically do isn't for everyone, but maybe it'll help you better understand the spot where this concept lives.

First, most database objects, like tables and functions, must live in some schema in PostgreSQL. By default the schema is 'public'. I actually avoid using the public schema in favor of using schemas I create. The reason I do this is because, some extensions and such will also define objects in the public schema and I don't want to confuse stuff from third parties with stuff I manage. By always creating at least one clearly dedicated schema for the objects I create, I know what software I'm managing vs. just got thrown into the dumping ground. I do this on all size databases I create.

If the database is sufficiently complex, I may create different schemas for different "modules" that I define in the software. It helps me to understand, in the database, where the boundaries are. For example, I work with an off-the-shelf ERP system. When I create extensions to this system, I will create a new database schema to hold the various tables and database functions required.

I may use PostgreSQL schemas to logically delineate different security concerns; I'll usually do this in conjunction with different authorization roles that have schema level permissions. I do this more often when there's need to define a database function "API" to the database. I'll put the data into a data schema, but then I'll create, say, two additional schemas... one to hold private/internal database functions and another to hold the "public" facing API. I can then have those applications/integrations that should always use the database function driven API to use a database role which only gives them access to functions defined in that schema. I don't mean to suggest that this is a "sufficient" security mechanism, but is part of a broader strategy of security in depth.

Anyway, some ideas to go along with the definitions.

I can't avoid mentioned Boccaccio's Decameron here. A group of young men and women flee to the countryside during the bubonic plague (it was written contemporary to the plague), and begins with an introduction where the author describes his experience (read the intro if nothing else).

From there, it's got a variety of stories that interact with a framing story of the people playing a story telling game. I find it a very relaxing book, the stories feel low stakes somehow, and are a mix between familiar chestnuts and others that are very strange for a modern reader.

Most universities don't pay property tax (maybe not most, but many are public and don't). They all have owned most of their land for over one hundred years. Buildings are expensive, but those are "one time capital expenses) and just plain don't add up.

What I'm saying is there is no obvious reason why a university costs more to run today than 1990,but tuition has gone up far more than inflation.

One good reason not to stop schools for two months as a replacement for summer break is that currently it is very uncertain that circumstances in the summer or at the beginning of the next school year will be anymore conducive to kids being in schools than they are now. Seems it would be much better to develop, trial and refine based upon real world experience remote teaching practices during the remainder of the school year and be in a much better position for the following school year if we are still dealing with this virus. Especially given that many experts seem to think there will be waves of easing and reimposing of restrictions until a vaccine is found.

The cloud is someone else's collection of computers operating at a very large scale. If my load changes in a way uncorrelated with other users', that's a very good thing. If my load is correlated with other users', that's may be bad. But it could still be good, because at that scale, they can justify having robust contingency plans -- back-up supply contracts, extra engineers around to ramp stuff up, or relatively unimportant stuff they can de-prioritize. (If you're relatively unimportant, that's a bummer; if you're a hospital getting priority, that's a plus.)
Rickover has a case to answer for the Thresher:

>Beneath the surface, however, was always the cold, unrelenting, ruthless workaholic, undermining the bureaucracy while creating his own. His was a management textbook for the inside operator, organized to the smallest detail, intolerant of error, devoting everything including his personal life to a cause, an obsession. Rickover established a constituency in Congress by superior salesmanship of his own product and skillful sowing of dissension and division in competing programs. Carefully slanting facts and covering up what he did not want disclosed, he skillfully manipulated his two bosses to become what the authors call "The Unaccountable Man." He destroyed any competing nuclear program within his own organization and any person likely to emerge as a competitor or successor. In time, he became increasingly conservative if not reactionary, putting space between himself and any responsibility for failure or accident. When the USS Thresher was lost in April 1963, he immediately phoned the Bureau of Ships to dissociate himself from any likelihood of failure of the nuclear plant in the incident. The bureau chief thought this action "thoroughly dishonest."

You're right that it's probably not much harder, but the current Postgres role is tied to the session, so you'll either be limited in the number of concurrent users (Postgres does not do great with high connection counts) or juggling SET ROLE around your connection pooling (which sounds dicey plus is just a lot of extra statements).

>The dedicated AES hardware extensions in ARM and x86 cores are probably the same logic anyway, so it shouldn't matter too much who decrypts the data. Maybe it's a tiny bit faster with the T2 though, because then the CPU doesn't necessarily have to pipe all the data through it's buses for decryption then. But that is more or less a feature of having a dedicated separate chip for it, and is thus not tied to the question of whether that chip uses ARM or x86 or any other ISA.

I don't really see how that would help, CPU i/o has to handle the exact same amount of incoming data encryption or not. Maybe a bit less RAM impact though.

Tbh, it’s exactly what I mean. The important distinction is that nothing has changed except willingness to pay so... rents have to go down to clear transactions.

Overtime, some landlords will hold out, but by doing so, they may lose money vs what they would make if they sign lower deals.

Bottom line, on the margin, rents will be lower.
You can use the cloud without your tech being deployed like a cloud. Heroku is a good example of this; very easy (and very cheap) to just get something up, and expandable from there.

After reading this, it seems the headline is a bit misleading.

The Microsoft blog post states:

So it's not an overall increase, just in certain regions?
I fully expect that a person who has only thirty days training will be worse than a professional and their relative incompetence will kill people. I don't understand how that is an argument against the plan to train volunteers though.

I'm reading that hospitals may be overwhelmed. I understand that to mean there will be more people requiring intensive care than capacity to give intensive care. If the choice is between the hospital sending people who need ventilators off to die and sending them to someone with thirty days of training and good intentions... Well, my intuition is that you'd have better outcomes with the latter.

The point is not "can we do this without killing people." Nope. More people will die with amateur ventilator-operators than professionals. What I'm suggesting is that more people will die without amateur ventilator-operators in the event hospitals are overwhelmed.

If we think hospitals are going to be overwhelmed in thirty days then the time to start training amateur ventilator-operators is now.

What good is it to have a 300 year old perfect body when you feel middle-aged and unwanted on the inside, and man secretly being taken care of by the animal-humans that he made is so poignant. His works were startling to me, really not like a lot of science fiction of the time.

You asked me a pretty insulting question. And don't ignore the 'or' in that sentence. If you think your question was fair, then I was not accusing you.
