I assume you mean highest buy (bid) is $90 and lowest sell (ask) is $100. In this case there would be no trade. This is also called the spread.

If you actually meant your original wording, theoretically whichever order came second would fill at the best price.
For some people, stating that poor countries might be remotely responsible for their own problems is a highly controversial stance.
Jeremy Charles Robert Clarkson went to a fee paying primary school and a fee paying secondary school.

Nowadays if you face a tool with sparse official documentation or with total absence of it, it's probably better to find another tool or be prepared to learn from the source code.
I have never understood why people in healthcare accept 12 hour or longer shifts in normal times. Now it’s coming back to haunt them. If normally they would have worked 8 hour shifts there would be more workers and now, in an emergency, there would be room to expand.
As someone born with a condition that gives me a limp, I would have to try very very hard to be offended at this headline. I prefer not to try that hard and am happy to employ a useful metaphor.
Company raises money from market by giving away part of the company.

If company shares are cheaper than other source of money, then company can buy back them, or other potential owner can buy them. It also sends strong signal to owners and investors about future of the company.

If company shares are costing more than other sources of money, then company can sell more of them to return costly money back or to expand business.

For example, bank rent rate is 10% per year. Company worth is $1 million. Company created 1 million of shares. 1 share is $1 of company worth. Company pure profit is 10% per year. Company needs $1 million in circulation to operate.

If company will rent money from bank, it will have 10%-10%=0% of profit. If company will sell 100% of shares, it will have 10%-0%=10% of profit, but this profit will go to someone else. If company will sell 50% of shares and will rent $0.5 million from bank, it will have 10%-5%=5% of profit, 2.5% will go to company, 2.5% will go to other owners. By reinvesting this profit, company can reduce bank money or expand company to worth more, increasing company profit share.
I think it's an interesting page. It shows human nature.

That the edit wars themselves (lame or not) can be query should be interesting for the students of the human mind and, maybe, even for future historians because it shows what was important in our time.

> but O(n^2.807) time on a classical computer

Optimizing matrix multiplication for classical computers is an open research problem, and according to wikipedia there are algorithms with O(n^2.37) running time. Also according to wikipedia, it is not proven that matrix multiplication can't be done in O(n^2).
What does "leet" mean?
The results in the "Brain Studies" section is based on a single 2011 study [1]. I just skimmed the study and the results are very underwhelming. Figure 1 shows the correlation between political attitude and size of specific parts of the brain (see image here [2]). This single figure raises so many questions: Why is the size of brain measured in "a.u." [arbitrary units]? Why not in liters or perhaps kilograms? Why are the error bars so huge? (Note also that the error bars correspond to 1 standard error, so about 68% of the distribution.) What does negative gray matter volume mean? Why were only age and gender corrected for? Edit to add: With these error bars, you can practically draw any line through them.

To be fair, the title of the paper is accurate, but giving this paper into its entire section on Wikipedia really overstates the significance of the results.

> if that path leads to a society we don't want to live in.

1-2% of people will be unable to live in the unquarantined society due to dying, and a significant number more may never fully recover. It's more "live free AND die".
I had to look this up, but I guess you meant ableist language [1], i.e. you're opposed to the use of the word "lame" here.

To me, not being a native speaker but having been part of the European demo scene 30 years ago, "lame" in the context of computing never means anything other than the opposite of cool, basically [2] which I of course assume is the meaning intended here.

I agree with you. It's a bit frustrating though, when moving towards language that doesn't harm any other groups of people, I lose so much of the color and succinctness of the language I was previously using; I find that I'm limited to saying minor variations of, "I feel negatively about that because of reasons (that cannot be succinctly said and make me sound like I care more about hearing myself talk than my audience's ability to listen)."
But you can click on the demo on their website and generate 3 Ws (wouldn’t it be nice if there was a convenient unit for this?) of energy fit each triangle you interact with!
"lame" is one of those words where virtually nobody uses it in its original sense of "unable to walk properly because of a problem with one's feet or legs". In fact, I suspect that if you polled a random set of teenage users of the word, few would even know this meaning, much less intend it when accusing a TV show, a new flavor of Doritos or their parents of being "lame".

As a somewhat tenuous comparison, should we stop saying "goodbye" because it used to mean "God be with ye" and it's taking God's name in vain?
I got a similar feeling from the last technical test I did.

"It should take two or three hours". The failed me on a long list of nitpicks, including not setting up mocks for testing, not running pylint (I would need to install it on my personal machine) not providing a setup.py (which was never asked for) and numerous other trivial things some of which directly contradicted what the spec actually asked for.

If I had actually done all the things they complained about it would have been closer to two days worth of work. Wankers.
you're preaching to the choir - my own DAW, https://ossia.io has no issue distributing tasks on their own cores. That does not help me at all when I just want to add that one more effect to a live guitar track.
> If the photon refuses to choose just 1 slit to go through, why does it choose 1 spot on the photo paper to land on?

The photon (as a field excitation) goes through both slits, but is quantized so only has enough energy to trigger a mark at 1 spot on the photo paper.

> Why do we not still have to consider interference in outcomes after the photon makes its mark on the paper?

If we want to be completely accurate, we should. However so many interactions happen so quickly that the law of large numbers quickly takes over and obfuscates the quantum reality. Technical term for this is decoherence.

> Why are quantum computers hard?

Exactly because of this decoherence. It is very difficult to keep the qubit state isolated from the environment throughout the computation.
It's also not like there are no problems outside medicine caused by the current situation. A hackathon won't solve those either, but can provide exactly the mentioned space to experiment and communicate can be the starting point for larger projects. I think the big recent ones didn't do a particularly good job at pointing people in the right direction though, so there's been a lot of projects that indeed seem questionable.

I.e. the platform that sprung up that crowdsources which stores etc closed and which didn't doesn't heal people, but has been quite helpful to find something I needed urgently. The grassroots effort that filled gaps in the PPE supply by scaling from a few hackerspaces doing 3D printed faceshield holders to organizing companies and community spaces to get parts injection-molded, material distributed, and shields assembled in the thousands is exactly about finding and connecting people with the right skills and resources. etc...
Ask HN: Database for storing machine learning data?
I'm looking for a database that can efficiently store and retrieve a very large number (billions) of structured datapoints for use in machine learning. Each datapoint can have an arbitrary number of categorical and numerical attributes and belong to one or more datasets.

I want to be able to quickly (ideally in several seconds at most for result sets with 1.000-1.000.000 datapoints) select datapoints of a given dataset and possibly filter them based on their attribute values, e.g. formulating queries like "give me all datapoints belonging to dataset A for which x < 4.5 AND category = 'test' AND event_date >= '2009-04-10'". Once written, datapoints will not change, though I would like to attach additional information to specific datapoints (e.g. test results or additional labels), which could be done in a separate data structure or table though.

Right now I'm solving this using a simple PostgreSQL database with auxiliary index tables, but I'm looking for more scalable alternatives.

I've considered software like Cassandra or Clickhouse but I'm not sure they will fit my use case well. Do you have any recommendations or did you realise such a system in your work and can provide some ideas or guidance? Thanks!
Austronesian languages have a reputation of being easy to learn, though I can't attest for this being actually true.
I'm not sure what people are reacting negatively to in your post but I thought this was a really well stated point:

"A nationalist self-image of responsibility doesn't count as Science"
1. Yes, scientists and policy makers know. But the average citizens who will be subject to these interventions largely do not. Western MSM has been extremely cautious not emphasizing the unpalatable elements of isolation strategies. And before that, the privacy breaking technical elements of contact tracing apps. These conversations are overdue even if societies eventually decide they are politically impossible.

2. This article is literally about US tech companies "refuse to budge" on standards a sovereign backed during time of extreme crisis. It may very be that Apple provided a better argument, but the language suggest Germany was rebuffed, that is, it was an unilateral decision on Apple's part. Germany just found out how little influence it has over critical tools to their security. This is arguably much worse than a Huawei moment since Huawei ostensibly has alternate supply chains whereas US companies own the software ecosystem for all mobile devices. The tech side in both scenarios are both going to be historically incidental, but the political ramifications will be long lasting.

Saying who decides covid19 is over is straight forward is like saying US declaring wars are over is straight forward. Maybe theoretically, but in reality not. What if EU wants these features permanent baked in as part of the future biosecurtiy system. What happens if G&A says no.
> NB I'd expect none of these very simple machines to survive to present day - in fact, I'd imagine there to be several generations of early life, each obliterating/consuming/sublimating the ones before.

That's another really interesting axis of this topic -- why was early Earth special?

There may be no environments on Earth today that are like early Earth, but we could probably recreate them. Wouldn't we then be able to witness abiogenesis?

Or, early Earth wasn't special and abiogenesis happens today. If so, where do we look?

Some amount of aberration is inevitable in spectacle lenses, because you're severely constrained in terms of weight and thickness. Most people don't want to wear glass lenses for safety reasons (they're legally prohibited in many jurisdictions), which further constrains the options available. There just aren't many variables to play with.

Smaller lenses will reduce how noticeable abberation is, but if you have a high prescription then I'd strongly recommend going for contact lenses.
Once your code grows and you end up with too many repos you'll be yearning to get back to monorepos. It allows to make changes in one go instead of having 3-4 PRs that all have to be merged at same time or otherwise the build breaks.

Having separate repos only makes sense if they are maintained by separate teams with a well defined API in-between that doesn't change often.
If the same team maintains all repos then it is just overhead, especially if you end up with a 100 repos and you have significantly less than 100 engineers in your team.

There are also potential build time savings when having a monorepo since you can do parallel builds across different subdirs without serialising at package boundaries.
Perhaps they damaged it while replacing the battery? Tested it afterwards and it failed?
It's worth considering that those words shouldn't have existed in the first place. How would you handle "lame" being substituted with something overtly racist?
As long as their backend isn't going to fail under a limitless amount of text, it's fine for this to be a front-end only limit...

But unless they've tested the backend against a 64 gigabyte gender...
In recent years most things calling themselves "Hackathon" sadly seem to emphasize the competition aspect. You quickly find teams, it's important to be really productive in the short time, theres big prizes for the winners, and the sponsor wants something in exchange. I tend to prefer ones that are more relaxed and cooperative. Often calling themselves "hackdays" instead?

An edit war being lame doesn't mean the article topic is lame. The lameness comes from both sides taking their own opinion and using the article to present it as the one and only truth.

An atheist and a christian could have an edit war on the article of Jesus, changing it between "Son of God and our Saviour" and "fairy tale character used to control masses", which would be absolutely lame despite the objective importance of the religious figure in question.

And while sensible people can at least resolve religious issues by accepting that they simply have opposing beliefs and no ability to disprove the other side, politics are even more complex in the sense that they include a lot of historical facts, not just ideological beliefs. This makes it more likely for people to feel like their truth is objective.

I had the same problem (also not native speaker). I first thought the problem here was the use of the word "war".

So people, please be charitable. Connotations of words differ, and English is spoken and written by people all over the world with different backgrounds :)
Eh - if you're trans and experiencing dysphoria it can be pretty painful when people misgender you. The whole 'did you assume my gender' thing is a sort of weird take on the fact that yes, it is pretty hurtful when somebody's going through a really hard and vulnerable time in their lives, then some douchebag is determined to make a political point that a complete stranger is 'really' x, or y.

It's also just really bizarre and rude. Imagine referring to a cis woman with a beard as an 'it', or 'he'. For whatever reason, people go out of their way to commit this kind of absurd faux-pas with trans people.
Since there appear to be no right answers and I love this topic, I feel the band's name should play a big role in its plurality. I would never say that 'Queen are a band' but I would also not feel like 'The Beatles is a band'. At gun point though, I'd choose the latter.
Are these descriptions mutually exclusive? Is a territory dispute inherently above heritage dispute (in terms of vanity)? When something escalates to violence, does it become less vain (supposing vanity is what causes "lameness")?

I would not say that people feeling strongly about something (and willing to act boldly because of it) somehow validates them or their conflict. That's what lameness means: is something socially accepted or condemned.
Yes and No, being from India myself i understand it is complicated. However western views are clouded. What the journalists and observers do not understand is that you cannot apply the same logic you applied to your own country and many good intentioned policies will turn out into tragedy of commons. This has been demonstrated time and again. This is why i have this unpopular opinion that what China did was simply unimaginable. Yes, they have their issues but a proper democracy where nothing moves (e.g. Sardar Sarovar dam on river Narmada was involved in litigation for over 50 years over increasing dam height which submerged some tribal villages, other side of the coin was it increased the irrigated land substantially ) compared to China where they executed more hydrological projects in 10-15 years than probably what the world did in entirety of 20th century. Surely some people were negatively impacted, but the outcome was net positive. We can argue about corruption, few people skimming the benefits but i think the Chinese society bargain with CCP is to ensure jobs, opportunities and development in exchange for no significant revolution. The misplaced idealism and token suggestions and projects that happen in Africa and India are useless. Only strong, difficult decisions that should've been taken decades ago would've made a difference. It is not possible to make everyone happy in one go.
As an aside I like the idea of using the EICAR anti-virus test file[1] as a way to "auto-delete" your data.

I suspect this plan might even work. I happen to maintain the libmspack library[2] in RHEL, it's a library for extracting Microsoft CABinet files. Part of the source contains regression tests. Some of those tests are flagged by AV software because they contain past exploits for the library: the idea of these regression tests is to ensure that they don't reintroduce the vulnerability by accident.

Well, the libmspack source RPM causes all kinds of problems, both internally at Red Hat and at customer sites. It is constantly being flagged by AV software. Every release I have to manually waive the package through our AV checks, and we've had feedback from customers that we're "shipping a virus" which had to be handled very diplomatically.

AV software is crazy, but let's make it work for us :-)

The stuff you can visibly see they've guessed about you is a tiny drip compared to what they've guessed about you but have no way to display.

Most vendors now simply a guess 128 floats about you as a vector which encodes your gender, your love of stars, your favourite foods, and how much you're itching to buy a deck chair...

The vendors themselves don't really know what's in the vector, apart from the fact it helps them predict ads. They couldn't explain it if they tried - nobody could - it's all generated by stochastic ML methods.
That’s not really the same thing. The US military doesn’t read books at people about how their plane should look fearsome when they are flying a hunk of junk. You have to occupy it to some degree, though I will give you playing the radio in the car can create an enjoyable synthesis of mediums.
Your approach works when you are around to accomodate changes easily. With more red tape in the process (worst case, code developed externally), the incentives to overengineer the the initial solution grow. As you point out, this is bad. But that's how I see things play out.

This won't help with everything you asked for but there is neat piece of software called Complete Anatomy that helped me with this sort of thing.

It renders an interactive model of the human body and you can toggle different layers, from bones to nerves, to various layers of muscles and ligaments. It also contains animations of treatment exercises/stretches, surgeries and highly detailed models of various biological components.

It helped me understand my injury and why certain exercises help. It's paid software but it comes with a free trial.
And it’s why bad players play it. Poker players should embrace luck because it’d the only reason whales exist.

I think the difference in is/are also reflected in the names of sports teams.

It sounds normal to say that an American team like Lakers/Patriots/Giants are winning while a British team like Arsenal/United/City is winning.
Just because poker involves luck does not mean it requires less strategy than any other game.
That’s often the case in research. For my first 6-8 months in my new lab I pretty much spend most of my mental energy finding how to combine my own research interests while fitting in the lab (i.e. do something that my prof would approve). It’s mostly solved now, in part by doing some side project secretly, but the big take away is that politics is actually an important part of how research is done in real life.
Yeah, strong claims especially around a political topic like this need strong evidence. I wonder what someone who has actually studied neuroscience would think of this. You've got to remember that it wasn't that long ago when there was "scientific evidence" that black people were genetically destined for a life of slavery.
Interesting idea. As jdietrich says, I presume the reason we don't see this is simply the question of scale and cost. If you want to catch kilotons of water, a reservoir is far cheaper than an enormous raised platform.

On the flipside, there's the question of how far down you can get the water to drop, before feeding it to your generator. This is something already taken advantage of - https://en.wikipedia.org/wiki/K%C3%B6lnbrein_Dam#Reisseck-Kr...
Isn't this just ARM with a european based distributor? I can't really gauge much about what's significant about them from their website other than "Hey, we're in europe".

If their geography is their leading feature I'd be worried.

For instance, If I go to oh I dunno, something random, let's pick Rockchip (https://www.rock-chips.com/) ... they lead with products, chips even, on the front page ... you know, stuff. Should AMD and Intel be worried about Rockchip and Unisoc? Probably more so than SiPearl I gotta admit. But that goes with arm in general.

If it fits in your pocket and you can walk around with it, it's probably running ARM, of course they are sniping upstream - classic innovators dilemma story.

Also the reporters inability to look up SOC really makes me think this is mostly hot air but we'll see.
