From a US perspective, I think it’s because people enter on travel visas and do not leave.

I had a coworker from India who was a naturalized citizen for 5-10 years and he was trying to get travel visas for his parents to visit. He had applied many times and been denied each time. We talked about it and he said that the reason given was that the state department considered his parents a risk to not leave at the end of their visit. Comically, when I complained about how that was wrong and his parents would obviously go back he said “100% they will stay, I don’t really blame the visa people. My in laws stayed on a travel visa years ago and are still here.”

There’s also a reciprocity issue that’s sort of chicken and egg. India didn’t grant visas easily back in 2005 because the US didn’t grant their citizens visas.
Why do all the tech? The goal is to have the ultimate model of just-in-time manufacturing: to never run out of supplies and, without sounding creepy, to know precisely what the customer plans to order and have it in a bag in and in their hands the moment they arrive at the store.

There are upstream benefits for marketing to see the feedback of their campaigns in real-time, but this is mostly about keeping inventories low and service times lower. That equates directly to profit.

CFA isn't the only chain working on this, but they're the most open about how they're implementing the infrastructure.
I found in a Tesla model 3 that I borrowed that even the maximum follow distance was closer that I would normally drive. It didn't feel dangerously close, just slightly uncomfortable - closer than I would have liked for a maximum.
Wow, that’s a very cool post!
That's an interesting calculation you have there. We wouldn't want something bad to happen to it. My associates and I offer coverage against unanticipated rises in gas prices. We call this prote^h^h^h^h^h insurance.

More seriously, I can see how this might make sense in the US, assuming that US domestic gas production and politicians can keep the fossil fuels flowing, but the calculations have much wider error bars where I live. For me, US$20k over 20 years is a lot of nights not tossing in my sleep while I dream uneasily of tomorrow's headlines.
I had this issue before -- I spent a long time trying to figure out what my brain told me was 'clever' code. For me it was 2 things:

1. Code that takes advantage of a constraint in an unexpected way (if you know the input will always be 'a' or 'b', you can write 'if not a:' and do things that assume 'b')

2. Code that allows for reuse in an unexpected way (you know these because the explanation in code review is 'in case we switch to system-X, we won't need to re-do this part')

Both of these are really cool in an academic setting because they're bonuses. They're like plot twists, only with code. However, in the real world, these are both pretty bad.

1 is bad because you generally don't know what constraints are 'fixed' and what aren't in your business. 'not a' might mean 'b' today but might not in two months. Your best bet is to make very clear easy-to-understand, easy-to-predict code so when you do learn new constraints you can quickly fix or extend the code.

2 is bad because it's usually premature optimization. Honestly think back to how many times you or someone you know has added code in this way, adding an abstraction layer somewhere or adding complexity because it will allow for extendability later, and think back to how often the code had to be extended in the way predicted. Usually this seemingly clever piece of code ends up being a weird extra step you always have to remember later ("oh, then we convert it into an array of strings and back into ints")

So I would say you should look at the applications you're building and think about what 'smart' code really looks like in your day-to-day and if the people you're talking to are creating such code. I'd argue they aren't, and one of the problems is that part of you believes they are, so you're having trouble articulating why they should stop and why it's harmful.
I don't like the article because it starts with a question that answers through a lot of jumps trying to essentially sell you the specific solution. Probably that is how they write articles in general from a couple others that I've seen but it would have been more fair to just answer the question in a simple way, yes because here are the specs sheets showing that

Expanding a bit more on my comment, the factor in sell stats from Scandinavia where home insulation is on another level and especially in Norway they just move away from fossil fuels in general - while they sell them elsewhere - regardless if for example EV batteries keep half the charge in winter time, just because they have money. Then the factor of house insulation in general, sure a much better insulated house can do with a not very efficient solution. And while they only touch a bit that every case is different, they don't discuss all the factors just the ones that can elevate the heat pump case. Doesn't it matter if this is a new installation with fan coils for example or a heating replacement case ? Electricity costs also, or this is a US specific sale ? and etc. etc.
As long as the heat pump was properly sized for such an uninsulated home it would still heat it more efficiently than a resistive element heater and just as completely. Of course, if saving money is what you want to do, then yes, insulate before throwing dollars at anything else.
And here I am, reading this in country were 30 days of vacation plus bank holidays are the norm, 24 days the bare legal limit and anything below 28 days considered exploitation.
Just move to any place that's had its workforce, welfare system and social order decimated by impoverished immigrants and given enough time to amass some awful experiences, you'll be able to list your own reasons.
I would say it's not so clear, and it's open for debate until hospitals open up their books.

Yes residents need to be supervised, but one doctor can supervise many residents seeing many more patients than they could alone. If hospitals didn't have residents they would have to hire more doctors.

Also consider that a resident costs less to employ than a nurse and that the hospital bills for all the work residents do.

Finally, doctors in teaching hospitals tend to be payed less than doctors in non-teaching hospitals.
>> Kazakhstan
For what's worth Russia said at some point last year that Kazakhstan is not a real country...it's actually part of Russia. If the Ukraine invasion works out for Russia(highly unlikely) I'm pretty sure these countries will be next.
Our grid is plurality natural gas fired, so I’d expect them to broadly track for the majority of the lifecycle of this equipment.

A slate roof precludes advisable/economic solar installation, plus the major part of heating load is in winter (obviously) and in the 75% of the day that’s not 9AM to 3PM.
Maybe your just are getting old, and have different taste than what the movie/tv studios cater for today. If you were a kid during the 80ies, today kids are going to be looking at the content from that time with the same view as you were looking at stuff from the 40ies-60ies.
Not exactly surprising that it’s in Sweden, as many rare earth metals were first discovered here and are named after Swedish things:

- Scandium from Scandinavia

- Yttrium, Terbium, Erbium and Ytterbium from the village of Ytterby

- Holmium from Stockholm

- Thulium from Thule
Discounting of cash flows is not what I consider to be “financials”. Financials are the output / cash flows themselves not the speculative investment calculation of future flows given a determined discount rate.

Initial cash flows weigh much more heavily than later cash flows, so initial losses in a cash flow series have a much larger impact on npv. Therefore, I disagree with the conclusion of your hypothetical.
Paywall, but this is also likely a fraud prevention measure. It's hard to cover your tracks when you're on vacation.

I disliked it intensely at first, but over time .. I now see the merit in it. I like XML, especially compared to everything else (that came after). It was possible to clearly define things.
Man, did Zweig ever have an ear for lyrically lush phrasing. His and Garet Garrett's polemics against strident nationalism unfortunately fell upon deaf ears.
Yeah, I was actually thinking the basic behavior that OP mentioned could be quite rare these days. Last project I worked on there was a whole startup procedure. You could even use a special bootloader that they kept in ROM, if you wanted... It did a number of other things that were generally not visible to the developer, but probably required some CPU interaction.
Who knows! Perhaps one of the necessary steps to conquering the distance between the stars is to develop robust robotics and the ability to somehow convert their consciousness into computer forms and cast off all the needs of their former fleshy bodies… vastly transforming the needs of such a society to primarily needing computers and energy for “sustenance”.
Seems ridiculously cheap to me. here in Phoenix, there are 2 restaurants near me that do by the slice, both around $5. Most restaurants don’t offer it.

I have only spent a month or so in NYC working a decade back, and at the time every thing was more expensive than home except pizza. I think every region probably has its cheap food for the working class. Here it’s tacos, there it was cheap slices.
If you look carefully, it's not: it's "rank" 49, but most ranks have more than one country, so it's actually down around 100+.
Could we have replaced the EdgeCommander with infrastructure tools like Puppet or Ansible?
That's an interesting amount, since I assumed things are cheaper in the US. I live in Finland and we got an offer for my house to install an air-to-water heat pump system (with an existing radiator network, which I assume you have too with your old gas boiler) for 13 k€ total. Is your house very big or what explains the huge difference, since you quote it would have been $20k more than some lower price?
Japan must be doing something well... I don't know if passport ranking is included in any human development index, but somehow being able to negotiate diplomatically with large numbers of "others" is evidence for an advanced society (and in some ways a role model if we ever want to reach some sort of pax humana)
I dont understand how heat output from a heat pump vs heat output from a gas / oil / wood burner / resistive heater are at all different.

Heat is heat, a joule of heat output by the system is a joule of heat ... or am I missing something?
Cypriot passport described as "DLC" gave me a chuckle :)
I've read about places that do this kind of stuff. Although it sounds like pure hell, I'm sure there's always a reasonable explanation, an intent. What kinds of problems was the org facing that led to the development of this?
Public goods exist.
Solid numbers (in either direction) are hard to find. Stuff like this is concerning:

https://ctmirror.org/2018/04/26/child-advocate-finds-homesch...

> In a study of six public school districts, Eagan found that over three academic years, 36 percent of students withdrawn for homeschooling lived in families that had at least one prior accepted report for suspected abuse or neglect from the Department of Children and Families.
So there are two problems as I see it:

Firstly you see analyses like these where the author goes "see, heat pumps work fine in cold climates, look at these success stories!", and then proceeds to list a bunch of places that aren't particularly cold. People think Norway is cold, but if you look at Wikipedia then the average daily low for Tromso (a random northerly Norgewian municipality) in January is -5.6C, with a record low of -18C. Compare this with Calgary, a relatively southerly prairie city with an average low of -13.2C and a record low of -44C.

The second problem is that they say "don't worry, if it actually gets cold it switches to resistive heat!" The problem here is that the extremes absolutely matter, because this is when demand is highest. If a prairie province/state switches everyone to heat pumps, then your grid had better actually be designed for everyone to be using resistive heat for weeks at a time, because that's exactly what's going to happen when you need it most.
Have you looked into using scoop? It installs everything into the user profile and won’t require elevation.
He didnt figure out the concept of online subscription and ads. It shows he wasnt that revolutionary. Just lucky, born at the right time to the right family and lived in right neighborhood/country.
Also worth adding that in the UK new homes will not allowed to be built with boilers by 2025 and they will need to be slowly phased out in next decades so definitely invest in home insulation and a heat pump if your boiler is on the way out!
Those are pretty compelling advantages. Thanks for sharing.
Why not, as many other niches, but 2 different links on the same topic, in a 5 minutes interval it's the kind of things that doesn't occurs that frequently, and it's usually for big news (either general world events or programming/tech world announcements).

It could be a coincidence of course, but I find it suspicious nonetheless.
When cannabis was first outlawed, there were all sorts of supporting arguments. Those were later re-evaluated and found wanting.

We can see the flaws in the current arguments for outlawing tobacco; but "this time its different" so we'll do the same stupid shit once again.
MovieSnackTime – stream content using webtorrent
It makes sense that explaining why xml is great doesn’t work. Maybe you can convince someone who’s never worked with xml. But if someone has used xml and thinks it’s a bad format based on those experiences, you’ll need to bring _really_ good arguments to let them think it’s a good format anyway.

Just ask yourself: could a comment here convince you that xml is a bad format? If not, why would the opposite work?
What pisses me off about this article is how it keeps talking about "degrees" and about Europe, but then you find out it's F degrees and not C degrees if you look at the graphs.

Please use SI units, but in any event, please place units next to numbers!
For bonus points, explain why that reason should apply to movement between nation states, but not to movement between the states of a nation state.

I think you've missed my point here. I am absolutely NOT advocating for communism. I am advocating for opportunity. Right now, we provide very very little of that.

We also ignore our own system's similarities to the failing parts of communism. Take for instance your own question:

>Do you stay in 1hr lines every morning to buy bread and milk? Do you need a year savings and connections to buy furniture or tableware

Of course I don't. Wasting an hour a day for essentials would be terrible right?

Instead, as a rich western capitalist, I waste 2 hours a day commuting to and from a job because our free market has totally failed to provide affordable housing for working people.

It would be madness to have a system where people wasted an hour a day getting bread. So how is it so sensible that the same people waste 2 hours because of crippling housing shortages?

You can do the same comparison with 101 other things like education. I am not required to work for the state to repay my communist state education on pain of arrest. Instead I am required to work for private companies to pay my student loan on pain of homelessness and starvation. But neither system has much opportunity right?
This was really a great read, as someone not real familiar with statistical process control-I wish I could vote it up twice.

Developers are happy to point at the idiocy of “lines of code written”, but rarely have I seen such a well-explained commentary both on why that’s bad (even though it doesn’t mention lines of code once, nor is it even software-focused) but how it’s bad, and what some solutions are.
It seems that the point is that the objective function is applied layerwise, still computes gradient to get the update direction, it's just that gradients don't propagate to previous layers (detatched tensor).

As far as I can tell, this is almost the same as stacking multiple layers of ensembles, except worse as each ensemble is trained while previous ensembles are learning. This is causing context drift.

To deal with the context drift, Hinton proposes to normalise the output.

This isn't anything new or novel. Expressing "ThIs LoOkS sImIlAr To HoW cOgNiTiOn WoRkS" to make it sound impressive doesn't make it impressive or good by any stretch of the imagination.

Hinton just took something that existed for a long time, made it worse, gave it a different name and wrapped it in a paper under his name.

With every paper I am more convinced that the Laureates don't deserve the award.

Sorry, this "paper" smells from a mile away, and the fact that it is upvoted as much shows that people will upvote anything if they see a pretty name attached.

Edit:

Due to the apparent controversy of my criticism, I can't respond with a reply, so here is my response to the comment below asking what exactly makes this worse.

> As far as I can tell, this is almost the same as stacking multiple layers of ensembles

It isn't new. Ensembling is used and has been used for a long time. All kaggle competitions are won through ensembles and even ensembles of ensembles. It is a well studied field.

> except worse as each ensemble is trained while previous ensembles are learning.

Ensembles exhibit certain properties, but only iff they are trained independently from each other. This is well studied, you can read more about it in Bishop's Pattern recognition book.

> This is causing context drift.

Context drift occurs when a distribution changes over time. This changes the loss landscape which means the global minima change / move.

> To deal with the context drift, Hinton proposes to normalise the output.

So not only is what Hinton built a variation of something that existed already, made it worse by training the models simultaneously, and to handle the fact that it is worse, he adds additional computations to deal with said issue.
We need smart vacuum robots which can (at least optionally) be fully functional without connectong to the Internet.
If you’re going to get a pre-owned RV or a used RV under $5,000, your purchase options are pretty much limited to private sellers and RV dealerships. For most dealerships, this price point would be a trade in.
As an electronics engineer, I always prefer millivolt to kelvin, so 21.528 mV instead of 249.817 K.

Special units for temperature are no more useful than yards or pints.
Yes it would!
MovieSnackTime is small project i have been working on back and forth over the last few years.
The key issue is despite claims that cold doesn’t affect heat pumps it absolutely does. We have an old house. When very cold the heat pump struggles to put out enough heat. It works well enough, but something to be aware off - go bigger in system than you think you need maybe
You can get air-to-water heat pumps (e.g. Chiltrix), and some manufacturers have refrigerant-to-water accessories for conventional systems. So you could have a heat pump heat your floors.
Very confusing indeed.
Manufacturer could include a sensor in the towbar.

Did the manufacturer think about this and include a warning? If not, how should the user know?
With streets crowded with scooters during rush hour I think we'd have a lot more minor accidents/injuries, but far, far fewer deaths, right? What could be done to avoid the minor accidents?
Does anyone have experience choosing/installing/using a heat pump for both cooling and heating? The weather at our house gets just below freezing in winter and very hot (38C/100F) in summer. Currently, heating is via wood burner, solar thermal, and random space heaters, and we don't yet have a cooling solution. House has thick stone walls and a tiled roof (southern Europe).
The lie / part skipped is while they “work” to those temps, they don’t work well.
The costs are totally prohibitive, though. We're talking tens of thousands of pounds, whatever direction you decide to take.

You could spend 10s of thousands of pounds in a "properly sized" heat pump system. Or you could spend 10s of thousands of pounds in insulating your home + a more moderate heat pump.
F or C?
True. If you’re on vacation you want something to ground your day’s activity and a story to tell the peeps back home.
It's a guesstimated million tonne of rare earth oxides .. it doesn't say in what kind of volume that million tonnes is diffused through (ie. how much has to be removed and sorted through) and then the oxides need to be processed to extract the actual rare earth elements.

What you won't see for a few years yet is an industry standard Economic Feasibility Technical Report - which outlines over a thousand pages or so the model of the ore, the exploration techniques used to create that model, various alternative costed plans to extract that target ore (and the value of any other material also extracted) and the expected value of the ore over the lifetime of the mining operation.

The key to this report is whether or not it's actually worth while to extract or whether it would cost more in earth movin and processing than the value of the result.

As for the tonnage;

> In 2019, Kiruna produced 14.7Mt of iron ore products [1]

this is the adjacent current mine and the location from which a drift is being driven.
Iron ore would be the co-product.

For comparison;

> Western Australia's iron ore output for 2020–21 was 838.7 million tonnes, the second-highest figure after 2017–18.

ie: big iron regions (all of WA iron mines are in the Pilbara) produce ~ 57x the mass.

Bear in mind that this million tonne of rare earth oxides would extracted over a decade or more, it's not going to be a fast hit all in a year.

I agree with most of your suggestions, but I wouldn't use "safe_load" unless the file has untrusted input (in which case, you could argue, you shouldn't be using YAML at all).

If you use safe_load then you'll get an exception if you use dates or timestamps, even if it's an unquoted string that happens to look like a date (but you can get around that last one by quoting).
1. Immigrants are a net positive for the welfare state because you don't have to pay for their education and all their young years where they don't produce anything. They come ready to work and pay taxes.

2. Expats who only speak English and not the local language are the one who have no trouble getting a visa anyway. To take the example of France, the countries from where people want to migrate (and can't even come with a tourist visa) are mostly African French speaking countries.

The writer is insultingly bad. In the first paragraph, they talk about temperatures dropping below -20, then immediately pivot to talking about -10.

A pump that works below -20 would be extremely interesting, IF the article was about that. It's not. It's standard heat pump salesbabble with catchy opening line, which happens to be 100% deceptive about what will follow.

It's so obvious and hackneyed, I want to sit the writer down and discuss their life choices with them.
