Central bank ≠ treasury.
Because police would likely not even contact him in the first place once they see that there's nothing extraordinary about his movements.
No, not a few. Most.
>If "just", say, 10% jump on board, what then?
Then it'll make little or no difference.
Or it will settle at 5.01% due to the fact that a middle eastern sovereign wealth fund or two will be bigger than all investors who sign up to this scheme put together.
>And considering that coal is not doing well (and thus has to offer higher rates), much of that money will be invested elsewhere. Sure, some will still be invested in coal but less than it would be if you didn't do that.
But that has nothing to do with global warming or ethics of coal. It's mostly due to natural gas becoming so much more economical, which is mostly due to the shale gas revolution. It's a huge benefit to the planet, but mostly an incidental one. Of course politicians and energy companies will still use it to pat themselves on the back very very publicly.
>This type of argument pops up often: "but there is a small counteracting effect, so it will balance out to not do anything". No, it does not work like that.
Depends on the scale of the pro-acting effect. My guess is that the effect of 'ethical investment' due to ethics/global warming alone, and not due to fundamentals of energy markets that have to do with prices of natural gas, will be close to zero. If I'm wrong, it'll only be because a majority of investors who would have otherwise invested in coal (important distinction) jump on board this campaign, or close to a majority.
The world is awash with capital right now, money sitting around idle, looking for a place to be invested. Just look at how much money is being thrown at startups, how low interest rates are for countries who were bankrupt or on the verge of bankruptcy <10 years ago. This scheme is guaranteed to fail right now. Maybe in another credit crunch it has a chance?
Are precisely the kinds of people less likely to be able to drive. Accessible and convenient public transit is a better option for them, provided of course that it's accessible and convenient throughout their journey - that means sidewalks, intersections, transit stops, building access, etc.
If families with 4 kids don't need a vehicle at all, it's a huge financial benefit for them. Here in Canada a mini-boat on wheels large enough to accommodate such a family is friggin' expensive. Cities tend to have free or very cheap tickets for kids, so if you can get away with doing commutes by transit and have a Corolla for weekend errands and groceries that you don't have to shove all 4 into, you win $1000s every year.

\* I should say this is anecdata, based on comments by several Iranian friends and acquaintances.

It's not legal. Your plates have to be legible. But much like many other portions of the Traffic Act, it's unenforced, so it's not really a "law" per se, more like a suggestion.
Just think of how many Indian and Pakistani lives have been saved because the two countries stepped back when shit was about to get real. Like, three times now. All because of nukes. Unless one of them truly commits to invading and losing millions of lives, their wars are guaranteed to peter out as border skirmishes.
I don't know enough about the financial industry to know if a real actual problem is being solved here. I do assume that any bank in this industry is already required by law to keep a record of all transactions, and that it's all digitally processed and stored. You'd have to hire an auditor to verify the blockchain software too, and even on the ongoing basis, to audit the infrastructure to make sure it hasn't been improperly modified.
Nah, it's the other way around. Specifically in this domain, innovation is definitely driven by domain experts (researchers, medical equipment manufacturers), and they contract out or hire technical expertise as they need it.
>To put it as question: do I really need to explain how open source works in theory and practice on a place like hackernews?
Your definition of open source is much too narrow and does not include what these researchers meant by it.
>Especially given that most of the world's infrastructure in practice runs thanks to the collaboration of millions who have built most of what we use in their "spare time" as you call it.
Certainly not in medicine.
>Same applies to DNN's(if not more so) - take any large DNN with the papers, data set and code to the author and ask them to give an explanation as to why it works as well as it does while it performs terribly on a different data set, even a similar one. "Well yeah, it's curve fitting which works here but doesn't work there". Why? ¯\_(ツ)_/¯
You've identified the precise reason why all this "machine learning" stuff has been such a dud when it comes to medicine. That is not good enough and never will be, particularly the "works so well on the dataset you overfitted on while performing so terribly on other datasets".
>My rant concerns a different problem - if you have such data and you want to share it, just go ahead and do. 1 of every 10000 might do something useful with it but we aren't talking about nuclear experiments where something can blow up, are we? Worst case scenario someone's cpu or gpu might overheat, big deal. Just ditch the entire bureaucracy crap, we have enough of that as it is in our daily lives.
They spell out the reasons for requiring a data sharing agreement in the data sharing agreement itself. They want you to cite it, they don't want you to sell it, they want you to confirm that you understand you're getting a dataset with no warranties, FDA approvals, etc.
And as I said before, the chances of you doing something useful with it may be 1/10000, but the chances of you doing something useful with it while not being motivated enough to sign a simple agreement and wait for the download link is essentially 0.
Spare-time tinkerers aren't really the intended audience here:
>>The neuro data set will allow researchers to test their models with data from additional machine types, new sequence types, and different coil configurations that were not present in the previously released fastMRI knee data set. Radiologists also look for different diagnostic properties (such as contrast in texture between different neural tissue) in brain MRIs. These differences present an interesting and challenging machine learning problem to solve and will help researchers develop models that generalize to more clinical settings.
It's unlikely in the extreme that anyone in that audience will be stopped by a simple data sharing agreement. And it's also unlikely in the extreme that anyone outside that audience will know what to do with a bunch of raw k-space MR datasets. Domain knowledge is an absolute necessity with this data.
Radiologists are notoriously conservative for that very reason. Dreamy-eyed image processing and computer vision researchers have been trying to get radiologists to abandon some of their caution for many decades. All in vain. "Hard pass", they say most of the time. The dream usually doesn't get as far as their malpractice insurers, but it certainly dies there if it makes it that far.
Rather than dreaming about that, the focus should definitely be on "clinical decision support", i.e. "something useful that will save a radiologist some time and won't just get in the way". Not too many examples of that exist right now. Even speech-to-text is not a solved problem in their domain.
This is certainly false for clinical MR imaging in Canada. The biggest component is the cost of interpreting the scan, i.e. the radiologist's time.
"regular full-body MRI scans for preventative healthcare could be feasible."
What's the point? What are you looking for? What is the false positive rate on that? Screening for the sake of screening is a mirage[0].
