You are proposing that a reduced dimensional projection of a large dataset cannot approach this limit?

I.e. expose the underlying low rank of nearly any huge sparse data matrix with an SVD or NMF. Enable fast recovery with a shitty (CS-wise) hash function. Recover most of the information about an observation's neighbors in a fraction of the time taken by many other approaches.

What's popular for ML benchmarking these days is not necessarily the same as what's needed for a specific application. It's a useful proof to keep in mind before prematurely optimizing with overly complicated approaches.

> With a bit of foresight there certainly is, your own domain pointing at gmail?

That costs money for the Google Apps Enterprise suite, and you're still dealing with a company that isn't known for customer service - you may point your MX records somewhere else but still can't access old emails when they terminate you for whatever stupid reason.

(Yes, backups are a solution but many people blindly trust the cloud)
Not sure why you're being down-voted so harshly. Google already has its own credit processing, mapping, routing, business management, and it's in nearly 60% of consumer pockets. A built-in (default installed) Android app which integrated with those services seems poised to make a serious run at market share. Drivers have no loyalty - better pay always wins. And Google doesn't need a profit, it needs only break even.

Though, it wouldn't really make sense given their business model. They want to know where you are, not get you there. If you have an Android phone, they already have that information. So it seems like an unlikely play.
> Does it happen to be a gap in the spectra of the atmospheric gases?

Yes.
Such remarks make me wonder if the so-called "Open Core" business model would ever be successful to the degree of investibility. Influx (clustering) and CockroachDB (backup) are good experiments to keep an eye on. MongoDB had to "port" it's paid feature to open source after a community backlash (which feature was that, I forget?).
Many routers use programmable NPUs because it gives them a 2-year advantage in time to market for new features. Also, the feature set of high-end routers is so rich that programmable cores may be less area than hardcoded logic.
Ok, let's think about the compensation process.

You start with the obvious -- managers assess the value of each employee. Roughly, for each employee you derive a dollar amount that is:
1. Larger than what the employee could be paid elsewhere (otherwise, the employee leaves)
2. Close to the employee's contribution to the company's bottom line.

That's a rough science though. #2 is certainly harder than #1.

So, next, you put all that data into a big database. Then you run a variety of sanity checks (aka formulas):
1. Large changes in comp, year over year
2. Discrepancies when broken out by factors including age and gender.

Finally, you're faced with a choice. If you override all of your initial estimates with the formulas, then you have formulaic comp. Otherwise, you're at risk to lawsuits.

Imagine a GOOG executive defending "yes, we paid women less because we honestly think, on average, the male employees contributed more to our bottom line." That's not gunna happen, which sorta leads to formulaic comp, no?
> Sometimes we might not get what we deserve.

Sometimes we deserve less than others. Gender/etc aside, some people are less talented/effective. Society seems to be afraid to say this, but not everyone is created equal upstairs.

> They both had four years experience.

Obviously, on the job years is almost entirely unrelated to pre-work experience, so this is just silly. I hope there's more to it.

I'm curious how their resumes/accomplishments compare for those four years.
This overly simplifies things. Passwords are primary authentication, biometrics are secondary authentication. Biometrics should only be used when a password has already been established, and then only as a shortcut to entering that password; furthermore, authenticating via biometrics should put one into a limited-access state that disallows tampering with primary authentication mechanisms. The result is that anyone spoofing a fingerprint would be unable to completely own another device.

The tradeoffs inherent to this are well-described elsewhere: a lower degree of absolute security in exchange for a higher proportion of users with any security at all; in lieu of the convenience offered by biometric authentication, enormous swaths of users leave themselves wide open. And since biometrics are just a convenience, anyone who does require absolute security can easily choose to forgo them entirely.
You've got it backwards. Life, liberty, pursuit of happiness are inherent in being human. Governments can only take them away, they do not confer them.
This might be true and I hope they win.

But unfortunately everything that they say applies to men too. I wonder if this due to lack of negotiation skills. I have seen this problem being under compensation for the same skill and peer levels for men too.

At work, In one case I discovered a colleague being paid almost 50% times higher than I was. In another case in only a casual lunch conversation I discovered a colleague at the same level having RSU's almost triple my entire compensation. I also discovered while I moved to US from India(I moved back for Visa expiry reasons) that some colleagues had even negotiated green cards through really acrobatic legal work. Promotions, foreign travel, bonuses etc.

Over 10 years in this industry I have seen ability to program well, or even do bigger software work like build scalable and stable systems isn't worth two shoes in this industry.

One must have the ability to be politically skillful, negotiate well, know how to be well connected up management and use that leverage to further your career in both money and positions. I've tried to learn this, and failed. Unfortunately this turns out to be not something you can RTFM and learn.

>I can rekey my house locks, I can change my password, I can.... what my fingerprints?

Years of poor security have taught us that we need our authentication to be easily changeable in order to be secure. It's not true. Passwords need to be changed because they can be guessed. They can be leaked. Any person sitting down at any keyboard could type any random string of characters and, given enough time, figure out someone's password. It doesn't work the same for fingerprints. There is no number of times I can press my finger on your scanner and trick your scanner into thinking I am you. Your fingerprint only needs to be changed if someone steals your finger and keeps it in a state where modern fingerprint scanners will still recognize it. That is exceedingly difficult to do.

We need to get it out of our mind that "we change our passwords regularly, we should change our fingerprints too". Bad security advice led to routine password expiration, and that bad security advice lives on. It's still bad.

>it's clear that fingerprints are closer to username than password

That is not clear in any way, either in theory or in practice. The entire argument works on "fingerprints are publicly visible and cannot be changed" which would suck for a password, but fingerprints are not a password. That's why there's an entirely different name for it. Yes, I can see your fingerprint. But TouchID isn't going to be fooled by a piece of scotch tape lifted from your desk, so it doesn't matter.

Fingerprints are neither a username nor a password. They are a uniquely identifying attribute. Usernames and passwords are not. There is no comparison between the two authentication systems.
> dont have the talent/drive etc

Don't have the talent/drive/connections/hustle/luck …. There are more possibilities than just sexism vs. meritocracy.

Edit: hey downvoters, I'm talking about why a random given person of any gender may not be progressing in their career. Read the context.
The average of an infinite set isn't necessarily a meaningful thing to consider. For example, what is the average integer? Well, you could argue that the answer is 0 because you can pair off the positives and the negatives. On the other hand, you could also say it's 1: pair off 0 and 2, -1 and 3, -2 and 4, etc.

Instead, the rigorous way to generalize the average is essentially to assign a probability to each member of the set, and compute the sum over the set of (n * p(n)), where p(n) is the probability of picking n, and the sum of all of the p(n) is 1. This is generally known as the 'expected value', and it has the property you want that the expected value of a set given a probability distribution is less than or equal to the maximum of the set.

On the other hand, you can't set p(n) to the same value for every natural number, since the sum of p(n) has to be 1 (because it's a probability). But the sum of infinitely many copies of the same number between 0 and 1 is either 0 or infinite.

So instead, you have to have some varying probability. For example, you might say you have have probability 1/2 of picking 1, 1/4 of picking 2, 1/8 of picking 3, and so on, halving the probability each time. And in that case, the average number of bits works out to be about 1.7.

In fact, you can show that for any way of picking a natural number at random, the expected number of bits to represent it will be finite.

Facebook has been subject to numerous patent litigations and is very likely to be involved in future patent litigations. Maintaining a defensive patent portfolio is an important part of preparing for such litigations, so Facebook's lawyers certainly aren't idly protecting their patents.
>Open reqs attract hundreds of unqualified applicants, at least, that was my impression.

In that case, what you can do is train your underqualified candidates. Create a system which allows you to train candidates for training and get them up to speed.

Kind of like manufacturing used to do.
How does this point invalidate their issue? All you've done is brought up another problem. Now there are 2 problems.
That only redirects the problem to a different level: you've got to rely on a domain registrar, a business ... similarly not recognised for its attentiveness to small-player customer service. And for which loss of control poses a whole higher level of problems.

I didn't say no treatment, just no coverage. If you choose to engage in risky behaviors/activities, then you are more than welcome to buy supplemental insurance as one of the costs of your lifestyle. It would likely be fairly cheap for boxers and runners. Possibly even offset entirely by their associated healthy lifestyles, and therefore eligible for default coverage on a net cost basis.

> It is ridiculous that people who make $250K or more a year (and I don't care where you live) think that they are "middle class". Bullshit. You are wealthy.

If you are making $250k/year through a job, and you depend on that money for daily life, you are not wealthy. You are a high-income earner. You can kind-of put your kids through private school and maybe even get a rent-a-maid more often than lower-earning folks, but if your yearly spend is close to $250k/year, you're not wealthy.

If you are making $25M/year through a job, and you depend on that money for daily life, you are still not wealthy. You'll be classified as an ultra high net worth individual by banks and money managers and qualify for a lot of cool rich people shit. You'll probably trade American or Delta for NetJets or Delta Private Planes (a benchmark a lot of folks in this article used as "elite snobbery," which it really isn't in many cases), or you'll make the mistake of buying your own jet, but if your yearly spend is >$25M/year, you're not wealthy.

Why? If you lose your job in both cases, you are screwed.

Wealthy is never having to work for your money because your money works for you. Having a high-income helps towards getting to wealthy, but you can also just buy more expensive shit with that income and just stay high-income.

The way I see it: you're wealthy when you can do, wear or say nearly whatever the fuck you want and not worry about your money/lifestyle going away.
Yep, exactly what the fb lawyers are saying.

These are the sorts of important sounding things that the lawyers are saying and frightening everyone into thinking just how incredibly important this issue is, how much is at stake.
Well yeah but isn't that exactly where the tragedy lies then.
I believe so and this guy was just an outlier dud who BS'd his way to an on-site round.

Fresh college hires are making 6-figures and it goes up from there, quickly. We use an HR market data firm to inform our hiring managers, but if you spend enough time in the market, you get to learn when you're never losing a candidate over comp or when you're frequently losing them over comp or getting strong counter proposals. I trust the intel we get from the candidates and market over what we get from the HR research company. (Boston market.)
Sure, but even the QA is basically a post/comment system adapted to solve a different problem. It's not so weird to take the lessons learned there and apply it back to general comment systems.

- The comments appear in a 'best' ordering.

- Bad comments get pushed down and hidden.
>At best, a fingerprint establishes identity

Nope. At best a fingerprint establishes identity in a unique and authoritative manner. My name is an identity, and anyone can say or write my name. My SSN is an identity, and anyone can say or write my SSN. No one else can speak, type, write, or otherwise express my fingerprint. That is far beyond simple "identity".
> the earth emits about 12 trillion watts per hour

Delete "per hour". The watt is already a unit of energy per unit time (1 joule per second, specifically). So 12 trillion watts is the same as 12 trillion joules per second.
As far as your phone is concerned, yes. Nine times, for most people.

Companies pay some employees more for pretty good reasons. I don't think they're thinking "Jim's a dude so we should pay him $50K more than Sally."

No, they're paying somebody more because they don't want them to leave.

And if they are paying you less than somebody else, it's probably partially because they don't think you are as much of a flight risk.

And if Google is wrong about these decisions, I'd guess we'd see a lot more female engineers leaving Google to start their own companies. But is that what we see?

> Finally, I also see it as another way of pushing for the uptake of SSL. With GAE doing this, other hosting services might also start offering something similar or close to it which would then beg the question - why is your site not using SSL.

Good question. Everybody should be on SSL. It isn't just hosting services that should offer something similar, but SaaSes too that provide SSL on custom domains for their customers. They usually don't get around to securing those custom domains due to the pain and inconvenience and maintenance.

There are platforms out there like Clearalias and Cloudfront that help with making that a breeze though, so I don't see why it would be an issue going forward.

Hopefully with Google and browsers punishing non-SSL sites more, there'll be more sites behind an SSL cert.

We are all salesman - and a better salesman gets better results. As nerds we tend to discount, dismiss, overlook, whatever, salesmanship skills. But they still count big time.

We sell ourselves all the time, like it or not. Might as well try to learn how to get better at it.

All aspects of ourselves can be tweaked to better our salesmanship - grooming, dress, posture, getting our teeth fixed, tone of voice, words used, email protocol, etc., the list is endless.

> Coq, Agda and similar languages are restricted enough to make verification possible, but complex—and expressive—enough to make it very difficult to automate.

Pretty much every theorem proving system out there is expressive enough to state whatever program property you want. You can't escape having to automate proofs though.

> Coq and similar languages are definitely quite expressive, but they're still complex enough to involve non-trivial manual intervention. Verifying something with Coq is possible but it's hard; whole PhD theses have been written around verifying code for a single program.

Yes, it's the most challenging aspect of programming I've ever tried. It's completely impractical and too expensive for most projects right now outside of domains where mistakes cost even more like aviation, medical devices, operating systems, CPU etc.

> The opposite extent would be domain-specific languages that are very restrictive but still powerful enough for their domain.

Well, see DML where you can only write linear arithmetic constraints so it's limited but automated: https://www.cs.bu.edu/~hwxi/DML/DML.html

I'm not really sure what the sweet spot is to be honest or if there is one when you require full automation. Even non-linear arithmetic is undecidable (basically arithmetic where you're allowed to multiply variables together) so you quickly get into undecidable territories for what seem like basic properties. No clever language design idea is going to let you side-step that proof automation is hard which has been worked on for decades. Even writing program specifications requires a skillset most programmers will have to learn.
As in lots of western countries we have a large amount of people form India in the Aotearoa (New Zealand) tech industry and quite a few in my workplace.

We're in the middle of an election right now with one of the political parties campaigning on forcing companies to make what they pay public so that we can ensure that minorities are being paid the same as others.

So, naturally the discussion turned to equal pay at work and one of the new Indian hires said that in India his boss told him that he didn't like hiring females and when he did he always paid them less as they were stupid and lazy!

That is obviously horrendous.

This isn't an attack on India, I've never worked in a workplace with gender bias as far as I've seen, but just because my experience is positive it doesn't mean that it's positive everywhere. There are good and bad workplaces in every country unfortunately and statistics back that assertion up.

Because I've never experienced anything bad it doesn't mean that bad things don't happen.
I've read in another thread here on HN that we also don't know the factors that go in. Someone listed off things like company title, marital status, # kids, car make/model kind of stuff. No idea if they were full of BS, but there's no requirement that the score is based solely on items in your credit report. We can probably (hopefully?) be sure that no race or race-correlated factors are included. (And same for other protected classes.)
Hi, I have a few questions:
