Certainly iron is the metal to look at if you're going for the lowest cost, but the results so far are not inspiring.

There are about nine orders of magnitude in between these results and utility-scale energy storage, but it doesn't seem like that's what they're aiming for—the existing flow batteries they mention in the paper would be a better fit. They seem to be aiming at home applications, but they are seven orders of magnitude away from even the “tens of kilowatts” they cite in their abstract as typical for such applications.

However, both the negative results they mention in passing and the positive ones are major contributions to the progress of such low-cost battery designs.

Iron costs around US$0.03 per kg, while lithium is more like US$300 and nickel is US$30. In the intervening 3 orders of magnitude, cheaper than nickel but not as cheap as iron, are aluminum, antimony, arsenic, cadmium, carbon, cerium, chromium, copper, lead, manganese, samarium, silicon, tin, titanium, vanadium, and zinc.

Some of these are unpromising precisely because they are too electronegative; zinc, as they said, cannot be reduced electrolytically in water; the same problem applies to titanium, aluminum, and carbon—but maybe a different electrolyte could solve that problem. Others, like lead, are already in common use for batteries.

Chromium, titanium dioxide, vanadium, tin and tin oxide, copper, manganese and its oxides, cerium, samarium, and of course lead seem like plausible candidates. Indeed at least zinc-cerium batteries exist.
Actually looks like everyone should claim 20 hours of your time wasted at $25 an hour and get $500 (Option 2 listed).

I certainly had a lot of time wasted trying to figure out what to do and then taking more actions to protect from possible consequences of their screw up.
Disk cache. That's been the great benefit I've had from the excessive amount of RAM I have in my laptop.
I was thinking that it is partly punitive. If you want to live in one of those places (and contribute to the rest of the waste of water there) you’re going to have to use a litter box to prove you really want it.

I would phase this in over time — i.e. no new construction or remodeled structures can include a toilet.
I have also had good experiences with Lightsail. We use the Tokyo node for an app targeting China. And unlike the Amazon free tier (older Red Hat) you get a choice of modern distributions.
Yep, but small nit. Farmers don’t really “raise their prices”. With commodities you can’t really raise your prices. You either sell at the market price or sit on it. And sitting on it is really dangerous with perishable commodities.

Look at mines, oil companies, etc for other examples of industries with participants lacking the ability to raise their prices.
You could probably hear your own heartbeat in those conditions...

> Most agencies will ask if you have instruments and likely deny or limit your apartment choices.

I would absolutely lie if I were asked about it. I don't play any instruments in my apartment except a keyboard with headphones, but I do have a lot of instruments.

Until they do...then you go from 100% to 0% as TFA states.

All it takes is someone figuring out how the NSA generated their magic constants (which obviously contain a flaw) and its game over.
The problem here is that what Boeing is selling ("737 that spends significantly less fuel and doesn't need recertification") simply can't be made safe. Whatever results from the marketing driven goal (selling something that doesn't and can't exist in reality) will remain unsafe as long as all the "already sold features" are preserved.

So it's not if they should "start from clean" but just accept the need for the new certification and then do the changes that are really needed. It will be less profitable for Boeing but it righly should be this time! They are killing people otherwise.
The analogy doesn't quite hold. We can see the outputs of the editorial meetings because they're released to the entire public. Whereas the outputs of Google and Facebook models are tuned to each individual, it would be an incredible privacy violation to share those with the government.

But this creates a problem of incentives. In mass media, bad behaviour is highly observable and more likely to be punished or regulated. For example, Australia has defamation laws that are notoriously slanted against the media. Political communication is illegal without the name and address of the individual who authorised it. And so on.

But when each of us sees a different feed, it is impossible to both easily detect violations of law and to preserve individual privacy. Asking to see the algorithm at least allows for correction of potential biases. I expect however that increasingly, these companies will be required to internalise that regulatory function on pain of heavy fines.

You won’t get it because the fund for $125 and $250 penalties are $31M each, so it will be prorated down if number of claims exceed the maximum number allowed for a $125/$250 claim.
Financial implications of exercising share options
In this case with regulated vs deregulated I meant whether there is some kind of open access scheme for generators, or whether there is a utility with both power generation and transmission in a monopoly position. Of course, even in such a deregulated market there are laws and regulations that apply to generators.

Well in Croatia OIB is a random 11 digit number, but still most people I know managed to memorize theirs, especially if you're an entrepreneur running a business and have to fill it all the time.
The FAA is only doing their job this time around because the rest of the entire planet, literally, was grounding the aircraft while the FAA baselessly stated the aircraft was safe. This is all stuff that should have been investigated after the first crash, not the second.

Has Boeing learned anything? Of course not. There are no executives facing jail time, or even fines! They're shameless frauds that outsourced their critical systems to the lowest bidder with predictable results.
It's easy to think of their "offer" as, "You do work for me for free, and maybe we'll make money."

It's more charitable to think of it as, "You invest some time into this, and I guarantee that both of us will make money."

They think that including you is giving you something, because you wouldn't have had the idea on your own.

You can respond politely in many ways:

- "Sorry, my financial situation doesn't give me the freedom to do unpaid work right now."

- "Here's an app I found that already does what you're talking about. What would you improve about it?" (It's often the case that the idea itself is unoriginal, and finding that out will kill their enthusiasm.)

- "Most engineers at my level are given salary and equity. If you can raise some seed money, I'd be happy to talk about being a founding engineer."

- "I like to consider every idea people present to me, but in my industry, we never write the first line of code until customers are lined up. Do you think you could get the first 10 customers/users in the next month?" (This will also shut people down because they don't actually want to start a business -- they want a get-rich-quick scheme with no investment on their part.)
If the endpoints are unrelated and you know them both before querying either, you can certainly query them concurrently from nearly any client language.

GraphQL can do it, but I don't think that's a big strength, compared to the dependent queries it can do. Using the results from one query to drive a further query without going back to the client will save a bunch of time if the client is far from the server.
FYI: “toxic elements” is a quack term when it comes nutrition. Everything is poisonous (i.e. “toxic”) at the right dosage level.

Also, a “nutrient” is just something that promotes growth and provides energy. That makes olive oil and sticks of butter a lot more “nutrient rich” than a pile of broccoli. Nobody will survive on the latter alone.
Medicine, as an applied science, consists of a spectrum of fields between areas that are largely ‘engineering’ and areas that are largely ‘art’. Surgery, for the most part, is something more like engineering/science, where we have most of the answers and don’t have to modify practice too much in response to new knowledge;
Psychiatry is still largely art.
Frankly, making an argument for the failings of medicine based on psychiatry is like blaming a 2 year old for not being toilet trained.

I agree that people are drawn to alternative medicine when they can’t get answers from doctors. And I am a vocal advocate both inside and outside of medicine for the failings of the system. For example, if I turn up to the GPS office and sit in a room of sick kids with paint peeling off the walls to be seen by a disinterested doctor for 15 minutes who sends me away without giving me a deifinitive answer to my questions/concerns; then later go to an alt-Med quack with a water fountain in the waiting room, incense burning and she spends 45 minutes with me listening to my problems, who am I going to come back to, especially if I derive benefit (there are studies showing that practitioner engagement and active listening are for many common ‘modern’ presentations highly effective)

Part of this is the modern world has produced people who are so healthy and generally well off compared to our forebears that the moment they develop an ache or pain they fear the sky is falling and demand an answer.

And medicine doesn’t have answers, or maybe not the answer these people want, because most of these things are just the process of growing old in and of itself - people are externalising their existential angst on a system that was designed to treat sick people, not the walking well.

For example, of the 17 patients I treated in the emergency department on my last 2 shifts, 9 of them should have never even turned up to the department. They had nothing wrong with them, or nothing that staying at home, resting and using some common sense wouldn’t have fixed. Yet there they are demanding answers to questions that our forebears would have considered part of life; and which in any regard we can’t fix anyway.

I don’t work in the US but the system there is so fucked that I wonder how long until it contributes to a broader breakdown in society; healthcare is a basic human right and you’re right the wealth transfer aspect of it is disenhartening and concerning.
Can you collaborate with others with your copy of Photoshop 5.0 or Office 2003?

I suppose that depends on what you're trying to do. I can still run those programs, and I can still access my data created in those programs. Obviously they don't support some features and formats that were added in later versions, but forward compatibility is a different issue. My point here isn't about new things being given to you free by magic, it's just about not losing things you already had.

But then I see lots of people asking for new features or are glad about new capabilities the app now offers. I’d say it depends a lot on the type of software.

Again, just to be clear, I'm not objecting to change in general. Of course in some cases we hope that our software will add useful new features or fix bugs or improve an interface.

What I'm objecting to is software that forces updates on users whether they want them or not, which Apple for example has a history of doing with iOS devices through a variety of mechanisms.

It has total control of the only major source of software on its platform, and it seems to have no problem with mandating that any software supplied through that store complies with its latest guidelines. As a developer, that might mean issuing a new version of an otherwise working app for essentially cosmetic reasons. Don't comply, lose your whole market.

Crucially, Apple also pushes new versions of its OS that bundle essential security updates with functional and cosmetic changes. You can't keep an Apple device secure without accepting everything else as well, even if the everything else makes your experience worse than when you chose to buy the device. This, to me, is the really nasty shift in recent times, and it's one that Microsoft is guilty of as well now.

You still get to buy some software or use your iPhone 3GS. It’s just a security thing. Or did you expect free updates to your OS?

Yes, if my product does not work as it should because of a defect, it is reasonable to expect that the supplier of that product should remedy the defect, or otherwise compensate me in some reasonable way for the loss caused by its failure. This is how consumer sales normally work, and indeed the principles are enshrined in law in many countries.

Software companies have had a very easy time on this score, despite the large number of bugs in what they ship, and I think that is in large part because of the informal arrangement that essential bug fixes and security updates would be issued free of charge for a reasonable period after someone made a purchase.

If software companies no longer want to uphold their side of that unspoken bargain, then I don't see why we shouldn't get stricter with them about consumer protection and their liability for failures. Obviously we don't know how to write perfect software and it's unrealistic to expect a developer to ship a flawless product, but let's not kid ourselves that huge numbers of corners aren't being cut in order to push things out the door more quickly, nor that those compromises don't sometimes have damaging results that were entirely avoidable.
If it were a slur of the ABC that it was far left, I would be happy. https://youtu.be/kxgeevlRElw?t=445 It was the managing director, Michelle Guthrie that was very quickly sacked and replaced.

Turnbull in his Oxford Union address spoke about maintaining the ABC's accuracy.

edit: Just to expand on Turnbull's point of view a bit here, because it applies with the social media angle. Turnbull's election run was plagued with fake phone sms's saying that he would privatize Medicare (gov health provider, loss making, impossible to run as private business). It scared some people to the point of voting the other way. He also struggled with social media stories about the way the world was run. The old thinking was to not dignify the stories with airtime. But that didn't work, so later on in his ministership, his party did what they could to get ahead of the stories and squash them, because social media gave them an infinite platform.

Turnbull defended the ABC's accuracy as a virtue, even though it speaks the other side of the political table to him, precisely because having an accurate ABC was key to having a verifiably true source for stories.

This is relevant to the discussion about the government wanting access to social media platforms that do not adequately restrict fake content.

I also share a belief that the ACCC works well.

>Other regulators and law enforcement have either suffered extensive "regulatory capture" (particularly APRA and ASIC) or mission creep (AFP, "Border Force" etc).

I have family that have worked in the banking sector. The regulations in Australia (up until recently at least) are strict to the point of boring. Maybe things have changed in the last 10 years, but the cases of fraud that are being dragged through the royal commission at the moment pale in comparison to the recession that was prevented by having sane regulations pre-2008.

I wonder how much correlation there is between answers to this question in 8th grade and "life success". We can define life success in many ways, including lifetime income, number of offspring, and overall happiness.

My guess would be that the young pedants who refuse to answer the question, saying "not enough information", do worse on average for each of these metrics than their more compliant but completely wrong peers.

Personal anecdote, but I’ve been tested for elevated adrenaline on 2 occasions just from complaining of facial flushing. Sometimes this will even be tested in a yearly physical. Surely, over a decade of interacting with doctors would have led him to this common test.

>Notably he wrote this over 100 years ago.

Is that notable in a good way or bad way? Anything written for the population densities and totals 100 years ago is woefully out of date.

100 years ago there were homesteaders in the western US who were given free acres of land just for being there.

I am much taller than average, way above the 99th percentile.

In some airlines I simply cannot seat, as my legs don’t fit. Sometimes flying is physically painful.

I don’t see why making passengers extremely uncomfortable should be a good thing.

If you think flying is bad maybe you should find some other ways of disincentivizing it, rather than making people that might be flying for legitimate reasons extremely uncomfortable!

I read through the whole article. It feels like a Kafka novel, and it's the kind of thing that makes me fear any institution with unchecked, unaccountable power over other people. Even if issues are discovered, there's no way to really solve them in the context of the bureaucracy and if you happen to be affected, you're just simply screwed. People either don't care or have some interest in the system being as dysfunctional as it is (see any number of US citizens being held indefinitely as "illegal immigrants").

This is an obvious attempt to control those algorithms because (a) why else would you want to lift the veil (b) it's not like some super hidden secret sauce: they train models to increase feedback signals and (c) those models are too complicated to figure out their effect unless australian MP's are geniuses. It has the potential to set out a chain of events outside Australia, since both the left and the right everywhere are waving their fists at google/fb. The result could be the first algorithm literally designed by a committee, and could cripple google's revenues. This should teach them a lesson, however, not to cozy up to any governement or take political sides.
I'm not sure what conditions you have in mind, but in the selection sort, the comparisons are O(n^2), and the assignments are O(n).

If comparisons are a fixed, non-zero cost, and assignments are a fixed, non-zero cost, then the comparisons in your selection sort will always overwhelm the assignments, and I can tell you at exactly which input size.
