It's a little odd to say a polynomial "isn't cubic" just because the degree-3 coefficient is zero. Ordinarily what matters is that every coefficient of degree higher than three is zero.

Think of the result that you can fit a polynomial of degree n to go through n+1 points. It's easy to show that the polynomial indicated by that theorem which goes through a set of collinear points must be a line (degree-1 polynomial), no matter how many points are given[1]. But we don't say "as long as the points aren't collinear, this theorem holds"; we just accept that a line is a special case of cubic polynomial.

[1] Proof: the polynomial of degree n going through n+1 points is unique. The line going through n+1 collinear points goes through all of those points, and therefore must be the unique polynomial of degree n to do so.

I do see in the wikipedia article, though, that "cubic surface" appears to be defined to exclude polynomials which have any nonzero term of degree other than three. It's a weird world. :/
Informative. Thanks!
Arbitration clauses are wrongly maligned. If I had a conflict with a company I'd want to do arbitration and civil litigation is my day job. The major arbitration companies are fair and professional.

The only downside is that arbitration is still too much like litigation.
That's true. In fact, if it's possible for Apple to accomplish what DOJ is demanding of it, the best outcome would be for DOJ to succeed, and do so publicly:

* There is an authentic need to get at the data on that phone

* There's no likelihood at all that other users will be impacted by the backdoor

* We'll all be on the same page about how secure these phones are versus the USG.

It's possible that they can prevail against the 5C but not against the 5S or later, since the security architecture of the 5S is very different from that of the 5C.
This is really great news more and more people now will be able to access Internet and connect with each other. My kudos to team who made this a reality and initiatives taken by Government of India to promote projects like this. A great deal of effort and innovation goes into keeping a price tag less than a coffee at Starbucks here in USA.
Even if touch id, it would be of no use. TouchID requires a password after 48 hours. or after the device resets.

Which is interesting. If you happen to use TouchID, is your best bet to hope a court will not be able to compel you to unlock it within 48 hours of arrest? That sounds very probable.
Now we're talkin'!

Your question is too broad to answer. Why not assume it's the same as for the readers of any other forum system, or for yourself? How would that assumption not be useful?

BTW, of your 14 submissions, 3 are AskHns and 2 appear to be your own writing on Medium. Are you asking us for help in how to SEO ourselves to read or reply to your content?

If so, there's a long process of trying to figure out what it is that you find interesting, which isn't already covered by others, and writing or commenting about it and finding an audience[1]. There can be shortcuts - "5 better ways to compile your code!" - but it's always seemed a crowded field.

[1] I have an interest in the early history of chemical information. Which has an audience of a few hundred people. I've been researching it as a hobby for several years. Any title will likely be unattractive to HN readers. :)
You're handwaving a lot more that that -- all maintenance and upkeep. Over 30 years you'll likely have to replace all appliances and the roof at least once, which could easily be 100k on a 600k house.

You've also got hundreds a month in day to day maintenance and upkeep, not to mention the taxes and insurance and hoa fees. Oh, and a point of PMI unless you've got 120k in your back pocket for a 20% down payment.

Don't forget 6% commission, closing costs and other taxes on the sale.

Buying doesn't pencil out against renting when the rent is lower than a 30 year mortgage payment.

I'll leave aside the question as to whether individuals faking their 52 hours is "ethically or morally wrong".

For Zenefits/Parker to facilitate and encourage their staff to do it is most certainly ethically wrong.

Telling your staff that they should cheat the rules, sign a false document and perjure themselves is completely unacceptable. Zenefits employees face the risk of jail time because they did what their CEO told them to do - that should never happen and Parker deserved to go for that reason alone.

Not sure on the battery life, but check out the HP ZBook G3. We have the G2 at work and it's quite nice. It's got a lot of horsepower and I can go 4-6 hours on battery.

I really wish people would quit with the "Trump scary" thing. Lots of people agree with a lot of what he says. He isn't manifestly wrong on everything. Because you have a different opinion doesn't make it a fact and it is becoming paraded around like one.

After five failed fingerprint attempts, your password is required to unlock the phone. That seems pretty safe to me. If you're ever ordered to unlock the phone, just touch an unregistered finger to it. Fingerprint sensors aren't foolproof. It'd be hard to prove you deliberately sabotaged the effort.

Though, one feature I'd like would be to register a distress fingerprint. Then I could touch say... my left index finger to require a password unlock.

Breaking the law is part of the "disruptive" entrepreneurship strategy for these companies. Incumbent companies tend to influence the law, not necessarily break it. For a disruptor to break the law, the company needs a lot of money to fight back.

Airbnb and Uber are managing to fight the regulatory hurdles with ~5x is ~13x the valuation of Zenefits, respectively. While Zenefits is ~5x the valuation of Aereo, it seems they have some catching up (read: fundraising) to do.
Thanks. So only recourse for highly resourced adversary will be to decode key via hardware imaging (not sure if any research has been done on this), and after that they will still have to bruteforce the passphrase used to secure the phone, the effectiveness of which depends on the entropy of passphrase.

I wonder what how Apple can help the law enforcement here.
I would hate to sound like a conspiracy theorist, but Malaysia's politics are quite a spectacular bowl of spaghetti. You have Saudi "donations" of billions, a Prime Minister who stands accused of using the country's Speciall Forces team for blowing up a Mongolian woman involved with a billion dollar French defense company purchase of Scorpene submarines. The accused murderer now resides in Australia. You literally have the financier of the Wolf of Wall Street movie, parties with Paris Hilton, squandering of billions of Malaysia's taxpayer funds. You have bankers being murdered in broad daylight. You have attorney generals being fired and prosecutors being found dead inside barrels of cement. You have Deputy Prime Ministers being kicked out. You have ex-Prime Ministers raising a 5 alarm fire demanding that the Prime Minister be arrested. You have apartheid policies being increased in the country. You have sudden import of millions of foreign workers, who have been accused of being used as false vote banks. So.... when they write "keeping secrets forever", that almost seems like what was intended for this flight.

I've bought old thinkpad T-series on ebay for ~$300, installed arch, and moved on with my life. I keep most of my relevant data on git repos or a home server. If it dies, which usually happens after a good few years, I just get a new one. Not ideal, and certainly not for everybody, but a reasonable option if it fits your needs.

Their argument would be that this hurts their portfolio companies as well so they are not incentivized to drive prices down.

I wish I could buy laptops that are not built in China. The Chinese army has zero scruples with regards to hacking. The hack where they got all US federal employees' info was an act of war as far as I'm concerned. I just don't see any reason why they would not be putting in backdoors into all the computers they manufacture.
The longer a person has been "dating" without settling down, or been in a failed marriage or two, the less likely that person is a long-term suitable partner compared to baseline. Of course the difference in likelihood may not be all that great, and if you find a partner who gives you other reasons to think they are suitable for you, you should go ahead.

But, to think that the population of people who have already demonstrated a lack of either desire, or ability, or both, to form a lasting intimate relationship with another human, is a better sample to draw your prospects from, than those who have not demonstrated these qualities yet, is a basic arithmetic fail.
I was looking for a place where I could discuss and show off side projects but couldn't find one so I created this chat on discord.gg. Feel free to join me and talk about your side project, bootstrapped startup, open source library, etc. I'm not looking to gain anything from this other than scratching my own itch so if there are similar established chat communities I've missed out on, I'd love to hear.
The point of being against Citizen's united is -- that money is lopsided as a tool for speech, and Company's aren't citizens and aren't protected under the laws of free speech, a company should have no say in an election, what's next - giving them the power to vote and making 1 vote from a company worth 10,000 votes from normal voters?

Not buying that Perl book at the college bookstore in 1994 and not really digging in deep when I first encountered RDBMs at about the same time. At the time I was learning grad level social science with a quantitative focus - lots of statistics with SPSS. Around 2012 I started adding in HTML, PHP, Javascript, SQL, R and now working on Python. I was right on the verge of putting together the multi-disciplinary skill set that serves me well today as early as the mid 1990s.
I think the bigger problem is the ability to sue unsophisticated end users, even when big fat suppliers, retailers or manufacturers exist and are easily sued. The only reason a patent holder would do that is to make the legal defense hard. This is a common troll tactic. Sue people with shady patents who can't mount a defense and avoid the big pockets who would invalidate the patent.
Although I tend to be anti-patent, the circumstances around the case are important and the eff didn't really provide them. The link, included, pointed directly to the ruling which I was unable to grok as a non-lawyer.

I found a more detailed explanation from a site that is "pro patents". Ignore the bias, but it's a good explanation of what happened here and I feel it's made it no less distrubing: http://patentlyo.com/patent/2015/04/lexmark-impression-facts...

The TL;(not-terribly-accurate)DR; is that Lexmark patented some elements of their toner cartridge and sold a "regular" and a "single-use" version at a discount with DRM to prevent its re-use. They sued a reseller that circumvented this single-use restriction and won on the "license" that states the single-use cartridge cannot be resold.

This is the kind of case that makes me hate the patent system when I'd otherwise be a proponent of it in spirit[1]. In the case of Lexmark, it appears they're using the patent system in order to continue the lousy practice[2] of charging very little for the printer while gauging the customer on the ink, a practice that I wish the patent system didn't enable. In all likelihood, they've patented some very tiny, novel part of the toner cartridge (perhaps the chip that prevents its reuse?) and are using it to enforce this sort of bait-and-switch.

I also hate the idea of enforcing a "single-use" rule via DRM and then suing to further push the idea that we don't actually own the things we buy. I'll avoid buying products that have these kinds of restrictions but if the practice becomes common-place, I expect I'll begin to have trouble doing that.

It makes me think of the little plastic cups I purchased for a family party I had last year. I was surprised to see them adorned with "U.S. Patents ####." So does this court order indicate that they can simply write a blurb indicating that they may only be used for a "Single Drink" and they can proceed to sue anyone for infringement if they fail to abide? That's reductio ad absurdum, of course, but there's many products/scenarios in-between that which are possible and likely if restricting your customers is your business model.

[1] In theory, I like the idea of giving an inventor who has created something truly unique a brief period of protection against incumbents, who will likely do whatever they can to either prevent the new product from disrupting their existing sales or copy a small inventor out of business. This is provided that the barriers for entry are particularly high. In tech, they're so low that it seems the only way patents are used is for predatory purposes by large companies.

[2] It's a bait and switch of sorts in that people pay less attention to price-per-page than they do the initial investment. It's this reason that I chose to buy a black-and-white laser printer the last time I purchased a printer (2005?). I've gone through two $35-$65 "compatible" toner cartridges since then.

Survival data is tricky to model. They have just done an overall average number of failures per running hour. There do seem to be a lot of factors not taken into account here such as drive ages, (in both running time and elapsed), etc.

With right censored data (as this is), if you measure age at death but then you're only modelling already failed drives, so you'll under represent good drives.

It would be good to see some statistics done so we can see confidence intervals around a hazard rate at different ages.

I used to use Uber quite regularly.

In the past year, I have had several drivers bring up, of their own volition, their dissatisfaction with the fact that tipping Uber drivers is uncommon. It is quite clearly stated in Uber's app and website that there is "no need to tip". I'm not a cheapskate, but I don't carry cash most of the time, and their veiled reminders/requests made me uncomfortable.

It probably sounds strange, but the ridiculous logo change on top of the changing driver culture have made me remove Uber from my transportation-method choices.

Fickle creature I am.
As an Australian, I came to say the same thing. I have one of the highest income brackets in Australia, when I choose to work. But currently I choose live in China. Renting. Why? All the reasons you mentioned, but also one big one...

Owing to the shorter engagement norm with any given employer, and the constant acceleration of change through technology, we cannot bet against entropy (unemployed, economy has tanked, etc.) as surely we once did. This is particularly the case for singles, who are faced with the entire gambit themselves, whereas traditionally more people were in partnerships which would effectively halve the chances of a particularly 'bad run', as it were.

In short, not only is it unaffordable, but the degree to which one takes ones chances even when committing to a long-term attempt at investment has increased significantly.

In my family, which is probably representative of upper middle class Australia, my brother has taken the conventional route and worked his ass off for most of a decade, and now has the deposit down and a fat mortgage on a shoebox with a view ... in conjunction with his 10-year long-term partner (they are unmarried). I on the other hand have studiously avoided such a commitment, living a year in London, a year in Hollywood, a year in Bangkok, traveling the world, seeing the Arab Spring first hand, spending months on end in 5 star hotels, having a family, and spending the rest of my time here in China, where I play with expensive toys like sailboats. In the end, out net worth is the same.

Most of my friends from youth in Australia, who are generally also higher income bracket people, are still unable to buy property or are locked in seemingly loveless relationships just to get past mortgage go.

My 'uncle' (actually somewhat more distant) recently sold the highest value property ever recorded in Melbourne (Toorak). He is the ex chairman of the board for Rothschild in the region, as well as ex-CEO of famous companies. When I last saw him, he said something is fundamentally broken in Australia, because his kids couldn't afford the downpayment on a house without his help (they have literally had all the opportunities you can pay for, and are not doing badly).

In Europe, the will to own is commonly seen as dissipated, in fact in Italy it has sunk so low as to be replaced by "the will to live away from one's parents", which many, many 30-something can ill-afford.

The world has changed. Travel gives you perspective. Individual countries, policies regardless, may have extreme difficulty changing this new reality. I say cheat. Leave your homeland, enjoy the differences. We are too intelligent to live stuck in a box. Eat someone else's young, or at least get drunk with them.

The employees who used it and then signed a false declaration are at risk of jail.

That was their choice, but they were seemingly under pressure from their CEO, so it seems fairly evident (to me) that Parker created a real problem for his team, even if the customers are OK.

Ok, but this seems pretty trivial compared to the many exclusive advantages R has.
I've had minimal problems using and extending other people's software packages written in R (for bioinformatics).
This has definitely not been the case with Java, R or perl, where just installing said software package is often unusually painful or impossible.

I think R is a prime example how useful a domain specific language can be. As such, I see Julia as the most viable replacement, although that will take a long, long time.

A lot of research has gone into information recovery from silicon inspection since it's tied closely to reverse engineering ICs. It's not the most trivial of pursuits but widely done.

There are some hardware HMACs (Atmel's in particular IIRC) where the process of opening the chip package destroys the area of silicon that encodes the private keys. I don't know if Apple used the same tech but if they did, any attempt to look at the private key storage would destroy it.

Hacking Wired's Ad Blocker Blocker #6f0
Welcome to the batteryless, wireless world of the IoT
A successful startup is one that has grown rapidly in recent years. No growth = not successful, and not recent = not a startup. Any tech company that grows quickly starts bumping up against any number of compliance issues, both legal (ie HIPAA) and private (ie PCI). Today's growth curves don't keep pace with many of these regulations. As you expand laterally into new markets you constantly run into new obligations. And as you expand vertically (increased sales) you trigger new expectations, especially the PCI DSS. The chances of anything rationally called a startup having accommodated these things is astronomically low.

Ask any tech lawyer to list all the laws applicable to a startup. Bring a lunch. Until a company has devoted resources (ie a full-time compliance team including lawyers) and has a decade or so of experience with the relevant rules, imho proper compliance is a pipe dream. At best you can hope to keep the wolves away long enough to get whatever they want ready asap.

Anyone here working at a startup, just have a look at the PCI DSS, specifically the SAQ you are meant to fill out every year (if you handle credit cards). And this is basic compliance 101 stuff, no lawyers required.
