Define "capitalism" [0]: an economic system characterized by private or corporate ownership of capital goods, by investments that are determined by private decision, and by prices, production, and the distribution of goods that are determined mainly by competition in a free market.

Define "free market" [1]: an economic market or system in which prices are based on competition among private businesses and not controlled by a government. (Note: the first definition is a bit vague, so I used the second entry.)

Hospitals aren't competing in a free market. They don't suck because of capitalism, they suck because of government intervention. Right now our medical system is basically the worst of both worlds--it's not affordable nor universal.

If hospitals and doctors were operating in a free market then it would lead to lower prices and an increase in quality. You can see some evidence of this in medical areas which aren't typically covered by insurance and are less heavily regulated, with laser eye surgery probably being one of the best examples.

You've managed to identify that the problem is government intervention, yet you appear to hint at trying to solve the problem with even more government intervention? Historically that hasn't gone over very well. Have you seriously considered alternatives? I believe a medical system cannot provide more than two of the following three guarantees: affordability, quality, and universality. This will probably be an unpopular opinion, but I think dropping universality is the best choice. You can still maintain a social safety net to catch people that fall through the cracks, and I posit that it would be cheaper and superior to our current system.

> Yeah, and if you ever had to leave the city, it was a multi-day dangerous journey by horse-back to get anywhere.

Not so much. There used to be inter-city rail that people used regularly.

This old railroad map (https://www.loc.gov/resource/g4121p.ct001917/?r=0.329,0.288,...) shows how dense and sprawling the railroad network was, even in 1900. Towns like Rhinelander, WI (and ones even smaller) that aren't even served by inter-city bus routes today had regular train service.
To clarify a couple of things:

(1) Calvin does support dependent transactions (it uses OLLP to support them.

(2) Calvin is just one example of a system that disallows arbitrary aborts. We've built a bunch of them in my lab.

(3) I do not believe that disallowing arbitrary aborts results in fundamentally new limitations of the system. You can still use pessimistic or optimistic concurrency control. You can use deterministic or nondeterministic systems. You don't have to assume you know the read-write set in advance. And you can certainly support dependent transactions.
I'd summarize it as:

2PC adds latency, throughput, and scalability constraints due to the coordinator role. If we drop an assumption (any transaction can be aborted at any time before it is committed), we can reduce coordination and get potential wins in the above metrics.
The point isn't that the AI won't improve or win with those conditions; I agree it likely will, and soon. The point is that the conditions of the match matter and that this one missed the mark.

It absolutely does matter whether the AI can use obviously super-human techniques, because then it's not nearly as interesting for human observers. I'd much rather watch an AI that was a strategic genius that won despite being hamstrung in terms of micro/techniques.

> There's no reason whatsoever to suppose that humans are fundamentally better at this game than an AI can be.

Who's claiming this?
The article covers the issues quite well. It's hell for the people who live on either side of the border, and relations with the authorities on the Canadian side have been especially bad - in addition to the protest about CBSA border guards carrying guns earlier in the decade, there was a violent land dispute at another Mohawk reservation about 30 miles to the east in 1990 in which two people including a Quebec police officer lost their lives (http://www.rcinet.ca/en/2018/07/09/shooting-death-police-ind...).

The smuggling issue is not just something that takes place on the Akwesasne area of the St. Lawrence, either. It happens throughout the Thousand Islands.
I live in Norway, and have for 5-6 years now. I'm 40. One of the things I noticed about the city I'm in - Trondheim - was that it was a walkable city. Between busses and walking, I'm usually set for transportation. We use the car once or twice a month for convenience (cat litter, for example). I don't have a valid license, so I don't drive at all and we didn't have any car the first 2-3 years I lived here.

I commonly see people walking in all sorts of weather - rain, snow, freezing weather and sun. Proper clothing makes these things tolerable in addition to simply getting used to it. I see pregnant women walking. I regularly see mothers with young infants in strollers. I regularly see elderly folks, sometimes with canes or walkers. In fact, I did some language practice in a nursing home and somewhat regularly went for walks with a few residents. The folks that did language training in a preschool were outside daily. The elementary schools have sleds and buckets for snow.

The combination of walking and public transportation usually works out well, and you do not need to be a healthy 20-year old to deal with it.
This is such a disgusting neoliberalism lie I’m unsure how to react.

There is nothing in the world to suggest that MORE workers would RAISE wages. I’m not saying it doesn’t add benefits, American tech companies built a lot of cool stuff with cheap H1-B but it does LOWER salaries.
They should just learn to code, like all those coal miners who lost their jobs.
This is amazing! :) I took portions of it before but motivates me to go back and work on it again. Is it just me or the overview notes from Lesson 6 & 7 are the same?
You might currently be working a job that is 50 hours a week -- or 60! Also with the example of a single parent they often can't make room for yet another 10 hours of a work in a week because they need to spend time with their children/take them to activities/cook dinner etc. Manageable when you are working 40 hours a week but it quickly becomes unreasonable. To me a job that wants me to work for them before I have an actual job offer is a red flag. I don't even work for them yet and they don't respect my time. What's it going to be like when I do work for them?
Without going too far down a rabbit hole, I think protocols like RAFT are fine for systems where you explicitly trust all of the machines in the network.

That being said, designing with "I trust all machines in my network" as a core primitive feels unreal. Most people don't have a full byzantine quorum style system, but if you're a big company it's totally possible one of your boxes got owned and is propagating bad data (hell, I'd even venture to say it's likely that some machines are owned in very big infrastructures). If that's the case, where do you put the protocols to control for malicious actors?

Quorum-based 3-phased commits can give strong guarantees at the cost of some performance (see the Stellar protocol[0], which is actually pretty amazing). It's really cool to be able to make systems like this. That being said, very few use cases have true byzantine behavior (most of the time the set of machines in your network that are malicious is really small), so I think it's pretty safe for almost all use cases to use something like RAFT (but again, you kinda need to explicitly acknowledge the threat model tradeoff).

The question, as always, is what performance metrics are you designing for and what is your threat model? If you know those things, you can make educated choices about how to build your distributed systems.

Do I understand then correctly that the:

temp = Do_Remote_Read(Y)
if (temp > 0)
X = 42

Is actually

temp = Do_Remote_Read(Y_i)
if (temp > 0)
X = 42

where Y_i is the value of Y in the version i that matches the version for which the coordinator created the code?

Otherwise Y can be something else? And isn't then there a need for a synchronization with the keeper of Y, if Y_i is still not available?

I'm an avid driver who lives in LA (Westside), and this sounds pretty great, honestly. Driving in and through DTLA is a total nightmare, and public transit has a hard time covering enough of the relatively large area.

I love being able to take the Expo Line to LA Live, especially for the LA Auto Show (amusingly enough), and would welcome more of that.
Agreed. LA took any love I had for cars out of me. Now I just want to live somewhere quiet where I can walk to places.
Oh boy, he just doubled down and said that if congress doesn't give him his wall he's shutting government down again on Feb 15th.
That's the cost of the emissions. What about the inefficient use of road space that comes from having highways full of single-occupant vehicles at rush hour, the larger roads required by said inefficiencies per given unit throughput as compared to buses or rail, and the opportunity costs of the land for the bigger roads or the money to build them?
Object detection is in part 2. You can use the 2018 part 2 for now. We had hoped to move it to part 1 this year, but couldn't figure out a way to make it easy enough yet.
I also recommend going to https://www.youtube.com/feed/music . It's a landing page that used to be behind a "Music" button on the youtube homepage, but has since been removed. But luckily the page still exists. It gives you a bunch of different playlists, including "Recommended" and "Latest Videos". I like the Latest Videos because it allows me to see what's "current" at a glance, even if I choose not to view any of them, I can see what' going on in the mainstream.
Yikes! Only 45 miles? I have a 2015 Leaf and it gets anywhere from 75-92 miles depending on who is driving.
The trouble with your position is it renders the person unable to get a job, i.e. it makes the situation worse.
It's a subtle change with great appeal to universalizing thinkers, but one which, as commonly formulated, makes many suggestions that seem intuitively wrong without adding a lot of qualifiers, and at that point you've just punted the task of formalizing ethics one level up.
That is a different problem needing a different solution. The problem at hand is transit and congestion in cities.

Obviously the automobile is the problem and bikes and public transit is the solution, which we can see has happened here in Olso but also famously in Amsterdam and Copenhagen before it. There is no excuse and reason for having cars in city centers, after you build out good bike, bus, and train transit inside a city.
very strange comment
Even if you logout, your anonymous session has its own set of recommendations. No?
My grandma never had a car in a major pedestrianized city. She lived independently until the age of 92. She took buses and walked everywhere. My other grandmother mostly walked around town.

My parents have a car but mostly walk around town.

Would I be right in thinking that you come from a car centric area where people don't walk and this lose their ability to get around at a younger age? Perhaps you have difficulty conceiving of life in a pedestrian friendly city.

If so, I don't blame you, there are almost none in the us.
I think this comment is actually so key and apt in this entire discussion. It almost sounds like some of the comments in this thread are like BAN all cars. But in reality, these efforts are really small, subtle fixes and actually probably make a lot of sense. And if we were to look at the maps of Oslo, the pregnant elderly people can still live, with a car, somewhere in Norway where they can still park AT the grocery store.

I heard stories of a guy who did this; was local, then went remote, and then didn't vpn in for months. There was a whole story around it, but ended up taking management a few more months to get him fired. This was a process heavy company obviously. But this AWOL person made at least 6 months of salary for not doing a damn thing.
The summary of his speech was:

If congress doesn't agree to fund his wall, he will shut the government back down on Feb 15th.

This isn't the classiest thing you can do, and a little risky if someone took it way too personally, but not the worst thing inn the world. But, ultimately, this is strong feedback to the employer that something is wrong with a manager or person, and at least deserves a closer look.
Public transportation can only win by competing with the alternatives.

When I'm in Tokyo I don't use Uber because the train system is so clean, fast, and safe; I have no incentive to use an Uber.

When I'm in places with slow buses that get stuck in traffic, or operate trains with disgusting facilities, I'm more likely to choose Uber.
Yeah. Given that coffee pots are the most virulent vector in the workplace, it seems unlikely that a button everyone presses with their fingers is not an important vector as well. The issue is getting germs on your fingertips, and then wiping your eyes or nose with those fingers.

If pump handles are a problem, I bet traffic buttons are as well.
One problem I see is when they write the pairs of metadata blocks for redundancy, in many FTL implementations they might fall on the same physical page of flash so there is not much redundancy. When FTL write metadata for their own needs, they are congnizant of the flash layout and make sure to write metadata to separate die/block/page.
> Amazon has explained in their reinvent videos that Aurora is the storage layer of Postgres rewritten to be tightly coupled to their AWS infrastructure. So it is just regular Postgres (they upgrade to latest on a slightly slower cadence). And there’s no benefit to getting the Aurora layer upstream, no one else could use it anyway.

I don't think this is an accurate analysis. For one, they had to make a lot of independent improvements to not have performance regress horribly after their changes, and a lot of those could be upstreamed. Similarly, they could help with the effort to make table storage pluggable, but they've not, instead opting to just patch out things.

How is Amazon meaningfully involved in the maintenance of open source postgres?
I am perfectly fine to give people with medical issues an exception. But that doesn't mean that we should build everything around cars. Cars also cause a lot of health issues which should also be accounted for.
Also wanted to add that as someone who hasn't professionally coded or have a degree in CS, the learning curve was a bit steep (which is why I took a break from taking the course).

The train network connected every city. It was incredibly dense.
No, optimizations are allowed to change the ordering or exact implementations, but they cannot change observable behavior unless the behavior depends on undefined (e.g the compiler is the adversary) or unspecified (in which the compiler is required to be self-consistent, e.g parameter evaluation order is (was?) unspecified so a compiler could choose left to right or right to left evaluation, but it must pick one and use that everywhere).

The C abstract machine defines the behavior, and optimization passes aren't allowed to change the behavior.

-ffast-math is the option that allows incorrect semantics (e.g commutative floating point addition), but compilers have a desire to do incorrect things for "performance".

I would hope it is obvious that changing behavior for performance isn't ok, but lets say it was. A compiler could change

y=1.0/fsqrt(x)

from (v. approximate, untested, and written in a text box :D)

movsd xmm0, $(wherever x is)
sqrtsd xmm0
movsd xmm1, $(location of 1.0 constant)
divsd xmm1, xmm0
movsd $(addr of y), xmm1

to something like

movsd xmm0, $(wherever x is)
rsqrtsd xmm0
movsd $(addr of y), xmm0

This would be much much faster, and vastly incorrect (IIRC rsqrt is only 12bits of precision)

Or even more dumb, remove calls to printf, because printf is slow.

A compiler does not have absolute leeway in all things, it is still restricted to ensuring that observable results of the C abstract machine are correct.
Specialist doctors do not make 1 million dollars (exceptions are generally those who run/manage their own business, or run a hospital - basically it's their business role that puts them at that salary range). You can easily look at job ads and see common salaries for different specialties, they very dependent on specialty but they do not even approach 1 million.

Children who live closer to busy streets are more like to get asthma. They also radically change how parents feel about just any street of modest traffic, or biking in general. With children more dependent on parents to set play dates, children have more difficulty getting anywhere.

Also, think of the people who can't drive and for whom getting someone else to drive them is too expensive. That’s a lot of elderly.

“There has been no increase in storms, in intensity or frequency,” he said.

And that's pretty much the consensus view, as far as I can tell. Why is G, F, or M sponsoring a conference at which some speaker states such things, or even more debatable things, at all controversial? Apart, of course, from the question of whether corporations should be sponsoring any sort of political event...
I mean, it's just another case of companies not paying their employees enough or not showing enough gratitude/valuing their workers. Employers just need to learn and understand the basics of how supply and demand work - I guess a lot of CEO and managers skipped that class or something. You pay more, you get more applicants. You treat them well/pay them well, they'll stick with you.

I think accessible public transit (as in, floor flush with the sidewalk), especially trams, and personal electric vehicles like scooters or wheelchairs, have solved that issue in Europe.
Couple of bucks. A gallon of gas emits 20-lbs of CO2, or ~1% of a tonne. Cost to remove CO2 from the atmosphere is roughly a few hundred $/tonne to about 70$/tonne depending on who's doing the estimating.
> If your boss is bad, resign as soon as possible with 2 weeks notice and wipe your hands of it

2 weeks is a guidelines, and there are a lot of exceptions for the guideline. To be quite honest, there are some jobs where I'd give more than 2 weeks, and there are other jobs where walking up to the boss and saying, "I quit" is completely appropriate.

IMO, ghosting is (almost) never appropriate. I think the only exception are situations of personal safety or situations where contact with the employer would have legal consequences. In those cases, I'd get a lawyer involved ASAP to handle communication with my prior employer.

But, getting back to quitting with less than 2 weeks notice. If a situation is truly miserable, but people are generally reasonable, (IE, no personal safety or legal issues,) I think it's best to explain the situation. I certainly would never expect a miserable subordinate to stay.

I once quit a beer money job on short notice. There were a few things promised that weren't delivered, and a few expenses that weren't explained. I didn't feel guilty.
Perhaps they too understand a free market requires ruthlessly eliminating monopolies and cartels. Perhaps they genuinely believe a functioning free market helps everyone. Perhaps the article is coming from this direction.

Or perhaps it's been noticed that it is better to reign in some excesses of rising inequality rather than potentially face the annihilation of wealth and chaos of the 1930s and 40s.
I doubt the climate in Netherlands is comparable. A week here and there with snow doesn't even compare. The pro car ban people mostly argue that if only the public transportation gets good enough, cars aren't needed. That remains to be seen IMHO. Until then I believe the shopping malls with parking outside the cities will grow bigger, families will be moving out, and eventually city centers will become less lively (like many places in the US, good for office space and lunch, dead in the evenings). Time will show. Regardless of this, I believe it is possible to have space for both bicycles and cars, although the people in charge of Oslo after the last election disagrees.
There is no separate snapshot system. Each partition just maintains multiple versions of all data it stores locally.

What an awful choice of a title. (Used to be something like "New Google policy charges devs $15k to access Gmail API")

Also, this isn't a bad move AFAICT (tightening policies and access to a very important API), but it's evidently a reaction to the backlash from that WSJ "exposé" about the scandalous fact that email providers allow third parties to read/manage your inbox... if you give the third parties permissions and access tokens. That was just dirty reporting and intentionally misleading average readers--the comments on that article were all akin to "I knew Google was reading my emails!". And I don't see this change mattering much to those people.
