What's great about evolutionary biology is that there is a science that explains sex differences and thus traditional social constructs that have existed for millenia.

> Because in humans fertilization occurs internally within women, men can suffer a lack of certainty in their paternity. In contrast, women are always 100% certain that their offspring are their own. Sexual infidelity, of course, is the event that can compromise a man’s paternity in offspring.

> Although women have never confronted the problem of maternity uncertainty, an infidelity by a woman’s mate can be extremely damaging. The woman whose husband is unfaithful risks losing his time, resources, and commitments, all of which could get channeled to a rival female and her children.

> For these reasons, evolutionary theorists have predicted that men, more than women, would get upset about signals of sexual infidelity. In contrast, women, more than men were predicted to get upset about signals of emotional infidelity

> In an American sample, 61% of the men, but only 13% of the women judged the sexual infidelity aspect of the betrayal to be the most upsetting. Conversely, only 39% of the men, but 87% of the women, judged the emotional attachment to the other person as more upsetting. Similar sex differences have been obtained in Korea and Japan (Buss et al., 1999), China (Geary et al., 1995), and Sweden (Wiederman & Kendall, 1999). In studies of memory, men can more easily recall cues to sexual infidelity, whereas women can more easily recall cues to emotional infidelity.

Men and women are not the same, and this is why they place differing values on sexual fidelity and the often-correlated concept of promiscuity.

And as female promiscuity increases in various developed parts of the world, you will absolutely see a decline in marriage rates, as men subconsciously process a greater evolutionary risk to their genetic investments.

EDIT - oh boy, this article really is full of gems that would offend the sensibilities of the egalitarian crowd:

> Married men tend to engage in especially vigorous mate retention efforts when their spouse is young in age and physically attractive. In contrast, women tend to engage in especially vigorous mate retention efforts when married to men who have good jobs, high incomes, and devote a lot of time to status striving.

What we value in a nutshell, whether we want to admit it or not.
There are even what I would call wide angle shots among them. I find that quite impressive considering medium & technology were relatively new.

I'm not an expert but it seems these perturbations are fiddling with the fundamental approach used with a NN. Mainly, that a NN works in layers. So these perturbations must be messing up the lowest layers and then the higher layers end up generating the wrong features and ultimately the model misclassifys. See http://i.stack.imgur.com/jpYdN.png
tl, dr: The guy just blindly copy/pasted the answers from the discussion section of each problem to the question itself and passed all tests, without even really reading the question or answer.

Is having a specific HackerRank meaningful to the outside world? I am unfamiliar with HackerRank, but solve algorithm questions on a site called LeetCode for fun. When I get truly stuck, I consult the discussion area and implement the suggested solutions. But I don't think it would be meaningful for me to go through all 450+(?) of their questions and paste in the answers.

What's the motivation to achieve Hacker Rank of 1, when presumably everyone knows you can just copy/paste the answers?

edit: as pointed out below, I jumped the gun on the motivation question. I guess I assumed the second part of the article expanded on the motivations, which were that the author heard people hired based off of HR. Hopefully those companies realize how easy this is to manipulate.

Interesting article but that PDF is 39 MB and took an awful lot of time to load on my browser.
Disagree. This is an engineering failure. You have to look at reality; it's often not easy to tell what kind of cable you are planning to use. Any command line interaction is decidedly more involved than the typical user plugging in a cable. This type of interaction should have been planned for and mitigated.

This also has nothing to do with UNIX.
It might be that you don't have the problem with peeling very fresh eggs the author is addressing. We keep our own hens, and an egg just a few days old is bloomin hard to shift the shell off.
It's interesting to note that the fancy LG 5k monitor announced alongside the new MBP also charges the MBP. One cable connection and you have a monitor, a docking station with ports, and power. All while leaving three extra ports free.

IMO, that's the real potential of this style of multi-use connector.
Most decent smartphones are already doing battery management and avoiding extreme draining or charging of the cells.

Think about it this way: If your phone has 8 hours of use, chances are the battery could really give you 9 or 10 hours if it was fully charged, but the manufacturer is software limiting it to prolong the life of the battery.
> IPFS content is chunked, your swarm is lan+wan.

Yes, but for offload, all that matters is your local lan swarm.

> A room full of people using their phones is what I have in mind.

That might work to some extent, but how often do you (i) spend your time in rooms full of people and (ii) have no wifi.

> Anyway, the point was whatever’s the offload factor it would still be a net positive.

Not quite. If the offload factor is sufficiently small there is no rational reason to burn battery on it.

> Also one can imagine if IPFS gets popular, just as ISPs collocate CDN caches in the present model, WiFi routers could come with a local node of their own. The “Web Accelerator.” And now we’re talking!

Possible, but unlikely. Web cache hit ratios are abysmal, normally it's much cheaper to just up the bandwidth. A lot of business models would also have to change for the (large) and interesting content to become third party cacheable.

> There’s opportunity for caching at many network levels, but there’s no incentive to do so with HTTP.

There are also many business models where there is no incentive to cache either.
> I think it just charges slower, it doesn't magically pump 87 watts over the cable, just 60.

Please do not post such dangerous unsubstantiated comments which illustrate your lack of understanding of basic electronics principles. Recommending a cable rated for 60W for an 87W scenario puts peoples lives at risk. Nothing "magical" about that either.

You are unconsciously incompetent. Take a USB cable and touch both ends to the terminals on your car battery if you want a dramatic learning experience. Wear gloves, long sleeves, and eye protection.
The GP had electric baseboard heat. That's a black hole for electricity usage purposes.
You're right. In some communities it's enough for a police car to come to your house for the neighborhood to treat you differently.
This... You're just going to up the crime rate. Easy access to guns is also working out so great for the US.
>Clinton and the DNC establishment support National Security Letters, NSA spying, PRISM, Echelon, the idea that if you're not doing anything wrong, you have no expectation of privacy.

Clinton, the DNC establishment and the Republican establishment support these things, and have for a long time. Don't forget it was Dick Cheney who tried to convince Americans to accept the "new normal" of the war on terror and attacks on civil liberties being necessary after 9/11.

Schadenfreude's fun and all but I'm not going to feel any better with Trump in charge of the kill list than Clinton.

Dear Matt Mullenweg: An Open Letter from Wix.com’s CEO Avishai Abrahami
that image also seems very black (the dog takes up most of the image) so the perturbations probably didn't have much to perturb. Also the perturbation is "universal" so it could have simply landed on the same classification.
Correct me if I'm wrong but this post does nothing to explain why the license of Wix's library is MIT while based on prior art which was GPL, thus infringing on the GPL license, which is the whole point Matt is discussing about in his initial post.
And I was just debugging a "pixel cache allocation fail" bug with GM: https://github.com/aheckmann/gm/issues/598.
Id hope most people realize how easy it'd be to manipulate.

Reminds me of the LinkedIn recommendation system is completely pointless as you can easily create dummy accounts for referrals. I doubt most people spend much effort investigating the peers and you could come across looking better.

There are tons of opportunities out there to be manipulative if you really wanted to be. Same with github repo example code and lots more.

Just depends if you personally want to risk it and put in effort.

He mentioned why he did it. Allegedly Morgan Stanley / other unspecified banks were hiring people based on Hacker Rank rankings
That very article (no offense, but did you skip the last part?) states the reason for this article, for this behavior: A report stating that someone was hired for a somewhat prestigious position, based on their HackerRank.

The article asks if this can be true and tries to prove that this would be a rather foolish metric.
I dunno... I've been meaning to write a post about multi-protocols on the same connector for a while.

Thunderbolt can run across DisplayPort and now both can run over USB-C. M.2 NGFF sockets can run mSATA, PCIe SSDs (either in AHCI or NVME), but not every M.2 or mini-PCIe Wi-Fi card will work in every laptop because of blacklisting (wtf?) even though they both attach to the exact same PCIe bus. Some M.2 sockets are only mSATA and can't take pcie/nvme drives. I'm pretty sure any M.2 drive can attach to the mSATA controller via an mPCIe adapter, but I'm willing to be there are some board that don't support that.

Why the hell are we doing multiple protocols on the same wire? It's beyond confusing. I thought with USB3.1, at least there'd be a universal cable, and I didn't realize until reading this article that the cables themselves are different per protocol!

I agree with what the writer is getting at. This is really confusing and it all feels like weird questionable design decisions.
Since there will be many occasions where power is being passed in on more than one of the USB-C connectors, the new Macs are designed to take power from the ONE charger that offers the highest power (capped at some limit) and reject power from all others. So, plugging in all four will NOT charge faster than plugging in just the one offering the highest power. This is a very explicit, intentional design decision, not some hidden side effect of something else.

GP: > Football games are universally 3-3.25 hours long

You: > "...college games average longer than your "universal" time you mentioned." is not an accurate statement

Your second link: > Football Bowl Subdivision games averaged 3 hours, 23 minutes (i.e. 3.38 hours long)

So it is a 100% accurate statement, even if the difference is small. Regardless, the GP asking if GGP watches or saying someone's statement is not accurate (when it clearly is) does not help the discussion. Games are long and not a subject worth being dismissive about.

Of course you can choose to make a dummy account and view the answers, but you'd really have to be desperate to do such a thing. And this is all pointless anyway.

It can also be the case that an algorithm with a worse big-O complexity might actually be better because all your inputs are small and the constant multiplier is lower than the more complicated, better big-O algorithm
What a perfect response. He evidently has cause to take Automattic to task, yet he turns the whole thing on its head for the benefit of Wix. Masterful.
Do you think Wordpress would make more or less money if they where open/closed source ?
Cloudflare claims unlimited bandwidth then says you are using too much bandwidth? Isn't this one of those blatant false advertising claims?

Over the past several months about 4 out of 10 companies that interviewed me actually required me to complete several HackerRank challenges because I did not have a HackerRank score. The fact that I have worked for several industry leading companies, and had 20+ years of development experience was irrelevant without that score. As a sr. dev manager, I found this to be an odd requirement.
Totally. We shouldn't be totally isolating ourselves and our own culture from this abominable behavior.

Like every few months there's a similar story involving some top 10 football team getting away with the same shit.
Its difficult, but not impossible by any stretch - the BBC stream the Olympics live, and have done for several iterations now, without seeming to have any major problems.

They've got an even harder problem, in 2012 they were providing simultaneous live streams from 24 separate events at times. Sadly I can't find any statistics on just how many viewers watched something like the 2012 opening ceremony, but I'd be surprised if the numbers weren't comparable to the Super Bowl.
It's a game of cat-and-mouse. A user can modify some variable names and get around naive algorithms.

If you eliminate too many 'pre-made' answers, then you get into a situation (especially for shorter problems) where you start flagging people who legitimately solved the problem, and just happened to write an answer similar to someone else's.
What does that matter? You're combining a ton of separate professional leagues. We're talking about the US here, ESPN's primary audience. I know that Soccer is very popular around the world, but that's irrelevant in this context.
They already have a lot of in house expertise in ARM. It could even just run their existing watch OS, enabling everything that already has such as display drivers, tools, firmware updates and boot system.

I don't especially love nil either, but people make too big a deal of it. The only arguments against it are hypothetical scenarios, anecdotal examples, and appeals to Hoare's authority. While there's probably a more ergonomic design, there's no substantial evidence that nil is the catastrophe it's made out to be. Using terms like "absurdity" and "catastrophe" seems overly dramatic without some decent evidence.
Premier league is not American sports. ESPN caters to an American audience, which is exactly what we're talking about here. How is that relevant? Few people here care about European sports. And why cherry pick media income? Premier league made 4B. The NFL is projected to bring in 13B this year.
If you need to process huge images, GraphicsMagick does some things that ImageMagick can't do. A few years ago when I was making poster sized art prints, I would routinely process 60k^2 pixel (4 gigapixel) images. Just a resize with a Gaussian filter would thrash and never finish overnight in ImageMagick, and only took a minute or two in GraphicsMagick.

I'm not in love with the CLI for either, but GM's is better and I like that it's all collected under one roof rather than a whole bunch of separate commands.

I do wish the projects could merge back into one and have the best of both. I also wish they were better at color handling, resizing needs to be done at a higher bit depth, better support for converting between modern color spaces, etc.

I love sips on my mac because it's fast, but I'm not sure if anything's a better cross-platform choice for basic batch operations on images, or for the backend of a web service, than GraphicsMagick.
There is no "no value" representation for int64. The only two cases are "<int64>, nil" or "<int64>, <error>".
In addition to spending $2400 on a basic 15" MBP, we can buy the fancy monitor that has actual USB connections for $1300 more! Don't forget a few $$$$ in dongles for the times when you aren't connected to the 5K beauty. +/- $4000 dollars for a "touch of genius"... Makes me vomit a little in my mouth.

I am the "tech guy" for my circle of friends. Apple has lost all recommendations from me.
I've read a lot of really cool papers on GCs that avoid this. The bigger problems arise from languages that take for granted that any abstraction they offer with a memory cost is okay because it offers the user no additional complexity.

For example, languages that use closures have to have very smart compilers or even innocuous functions can create implications for the working set size, which puts the allocator and deallocater under a lot more pressure.

And that's not even the most subtle problem you might run into! A common cause of memory constraints in Java 1.7 and earlier stemmed from subarrays of large arrays. Java made a fairly innocuous decision regarding methods like String.substring that ends up biting a lot of people later on, even as it is the right decision for a slightly different set of performance considerations.
the poll that your article cites from another article. and like that article says, (which maybe is why didn't you just link the original article) Rasmussen's polls lean conservative. there is definitely some people not watching because of the protests, but there are people who are just tired of goodell and the dumb crap he pulls.

did you hit your wife? 1 game unless the public starts getting more angry about it.

smoke weed? 6 game suspension. no no, make that 8 games. or drop 20 spots in the draft.

celebrate on a touchdown? flag and a $20k fine later.

deflating some footballs in which your team was already punished for doing so but you destroyed your cell phone and now you're making me look dumb? 4 games.

all of this and the huge cte stuff the nfl wishes would go away has turned me off to watching any kind of football at all.

so... maybe the protests? i bet a large majority of those polled still watch the nfl anyways, even as i sometimes do despite my frustrations. i know a lot of fans who don't give a shit about any of the above. they just want their team to WIN.

but the fact of the matter is, the nfl product is terrible this season. it's just not very interesting at all unless you're one of the 5-1 teams
> the cables themselves are different per protocol

I feel this is a transient rather than inherent problem of running different stacks over the same physical layer. If the physical layer can "miss pairs" then I agree we lose the whole point.

One way is to have some sort of official certificate system enforced by USB.org and adopted by major manufacturers. Basically "guaranteed to support a few pre-defined subsets of protocols".

You can't 'steal' GPL code. Just like you don't 'steal' a movie when you download it.

It's so funny how people in this community change their tune so quickly when the agree or don't agree with something. I can remember the last discussion about piracy and the countless amount of people that proclaimed that a movie or a song can't be 'stolen'. This is the EXACT same principal, and words like 'theft' and 'steal' are used to describe it.

Hypocrisy much?

It means to me that people really don't have many principals and most things are used to justify their own illicit behavior.

Totally agree about prevalence of 4326/3857 as a net positive. Given I still find projection/coordinate representation a little tricky, I think the chances that widespread education on the subject would ever exist to be pretty slim. Might as well just have a good default.

Displaying state/country level data using EPSG:4326 isn't great, thankfully it doesn't happen often.
It's definitely not just esports. I've noticed more people in their twenties are getting into football (soccer) and x-games style alternative sports. I don't see the domination of NFL, NBA, and MLB continuing for many future generations.

College sports completely baffle me.

These types of game replays exist for both hockey and soccer. You lose context sometimes but for the most part the games remain cohesive and very exciting. Showing every pass, penalty, goal, turnover, and assist only couched by a few contextual seconds on either end of the clip gives you the full impression of the game without costing you an entire night... with the only setback being that you can't participate in the next day water cooler, if that's your thing.
