You couldn't even name a paint by a short number (like a hex code) if you wanted to. That only works because we get to think of colors in terms of three channels, a mix of red/green/blue. Cherry (brand a) and Cherry (brand b) paint could look identical under daylight but totally different under incandescent.

To define an actual reflective color of an object, you need a spectral reflectance distribution. This measures what percent of light is reflected at any given wavelength.

http://hyperphysics.phy-astr.gsu.edu/hbase/vision/imgvis/spd...

Then the actual color you see depends on the spectral power distribution of the light source. For every wavelength, you multiply the amount of light of that wavelength by the percent of light reflected at that wavelength, and you end up with a new spectral power distribution for light coming off the object.

That goes into your eye, hits the retina, activates three types of cones in some proportion, and your brain turns it into a perceived color.

Incidentally, the image linked above includes a tomato. “#FF6347” doesn't cut it.

More info (and image source) here: http://hyperphysics.phy-astr.gsu.edu/hbase/vision/spd.html

Pantone works because it's a lookup table that maps short names to a set of predefined reflectance distributions. In the real world, that's as close to hex colors as we can get.
Let's be frank : the probability it's a "she" is so close to 0 that we can say "he" without passing for horrible misogynists ;-)
And I think that the older girl (the one that was shot and beaten) talked about a "bad guy" in her statement btw.

I think not picking-up the brass doesn't mean anything : you can find the imprint of the barrel's grooves on the fired bullets (unless they are too deformed by the impact, but would you bet it on all 21 bullets ?) so the gun will be identifiable even if they don't have the brass.
The initial page load matters a lot. That's the one where the user is deciding whether he'll be coming back to your site. The unfortunate thing about many caching technologies is that they speed up subsequent page loads, but do nothing for the initial one. You still need to pay attention to clean-cache load times. Indeed, it can often be worth it to pay a cost on total page load time to get first-paint time down - that's the time at which the first visual representation of the webpage appears, even if it's just the header, layout, and a bunch of boxes.
I can't see your opportunities because the iframe embedded is having too many redirects. Just a heads up. :/
I'd add to that in that we are not only complex, but complex in a way that makes us the sole bastion of models of relevance in the universe, and that this capability is relatively fragile.

I'm personally trying to get more of my projects out into the open, even before I feel like they're ready - having code I put lots of time into that never gets seen by anyone makes me feel like I'm wasting my time. But at least getting some feedback helps me build better things next time.
It's tempting to criticize the decision to hire Rice based on weak spots in her track record, but we should resist the urge.

In reality, Rice could've been recruited because of her relationships with top govt. security officials, in the hopes of facilitating more conversations, in which Dropbox has more leverage, to push back against mass surveillance.

If something like this isn't the case, then firing Rice wouldn't be a resolution anyway.

Logically, if the U.S. feels justified in targeted drone strikes against legitimate threats to national security, what's to stop China or Russia from doing the same? Arent there some legitimate scenarios where U.S. and Chinese national security interests are in opposition?

Where's the evidence to support this sentiment? I see it all the time and it looks to me that people just take it on faith that computers will be better.

I mean, here on HN, discussions of computing products like phones and operating systems are full of complaints large and small about problems, shortcomings, etc. Are there any programmers here who think their product is bug-free and safely survives all edge cases?

There just seems to be a huge mismatch between how people think about computers they use today, and computers they expect to drive their car in the near future. But it all comes out of the same companies and software development processes.

I also don't think people know the stats on car safety. The injury rate is 75 per 100 million miles traveled. About 35,000 people died from vehicle accidents in 2013. That sounds like a lot, but more people died from the flu, or from falls, than died from cars.

I won't deny that vehicle travel is dangerous, but the question is why we think computers would be better at it than humans, who are already pretty darn good at it.

Local television stations (__not__ networks - although there are a small number, limited by law, of network owned-and-operated local stations - usually the biggest markets), which may or may not be affiliated with a network (CBS, NBC, Fox, ABC), broadcast the signals.

If a local station is affiliated with a network, they've agreed to broadcast the network's prime-time feed (7pm - ~midnight) including the national ads that the network has sold to large brands.

The local tv stations get (not very many) ad spots to insert in between national ads. The local tv station does not generally get any revenue from the national ads (the big ads for big brands - Coke, Apple, Nike) and only receive revenue from local ads (Stu's burger shack down on main street).

There are also open slots where the national network does not have shows scheduled and local stations can broadcast locally produced shows, News, and, sadly, tons of infomercials. This is the non-prime-time - daytime, weekends and late night.

If the show being broadcast is locally produced, there are generally more open ad slots for local ads. It is possible that the local station also gets a cut of national advertising during that show.

The local TV station has purchased the exclusive right to use the frequency/channel (in a particular "market") from the Federal Government, but has to provide, as part of the agreement, a number of things, "to promote the public welfare" - such as educational programming, community service programming, and a few other things.
It depends on your local station; my Fox affiliate does have subchannels. But the Fox network is only 720p anyway, so they should have the bandwidth available.
I don't see why his theory would treat stock investing differently. Trading in public would still be harder than doing it through your computer.

The expected value of trading stocks is at least slightly positive. If you invest totally randomly, you will, on average, win more money than you lose. You still lose money in fees and stuff though. But you are at least starting from a positive sum game with a positive expected value.

Gambling is the exact opposite. It's all a zero sum game. For everyone that wins something, someone else is losing something. At best it's exactly break even.

People absolutely would switch away from bitcoin if something better came along.

If people would rather use something else to trade with, bitcoin stops being potentially widely used in trade.

If bitcoin stops being potentially widely used in trade, it stops being a potentially good store of value.

If it stops being a potentially good store of value, it stops being something people want to speculate on.

If people don't want to speculate on it, the price crashes.

In other words, the whole value proposition of bitcoin rests on the idea that it is useful for trade.

In other words, that you'd rather use it than at least one of the set:

{credit cards, cash, paypal, regular wire transfers, wire transfers involving foreign currency exchange}.

That said---I have not read the Bitcoin-NG paper yet but others are saying it is highly centralized, which would make it a non-starter.
Same idea as Google, Youtube, Facebook, etc. The business model has existed for far longer than the internet.
It's not like America is killing people for fun or some petty economic gain.

How do we know this, again? The folks who have said this are legally bound not to say anything else. So they're not particularly believable. The Snowden revelations about PetroBras hacking somewhat (but not totally, admittedly) makes me very suspicious that network penetration goes on for petty economic gain. Why wouldn't that leak into drone strikes?
You're right, but the point here is that positional queries are boolean queries plus positions. For example, document that match 'a NEAR b' are a subset of documents matching 'a AND b'. So if 'a AND b' has no matches, there is no need to execute the more expensive 'a NEAR b'.

I agree that this wasn't done by the computer (did computers uncover the Higgs Boson?) but I also do not believe humans can take most of the credit: this was the result of a Man Machine System team up—trying to disentangle credit assignment is not a worthwhile activity. Roughly and from a quick reading of a paper thickly frosted with jargon I am unfamiliar with, the method works by creating networks—which highlight key relationships—for visualization by searching for stable clusters in a reduced dimensionality space of the variables.

Humans are there to explore the visualizations, interpret the network structures and understand the clusters and variables. The machines are intelligent too; they do the heavy work of comparing large numbers of points in a high dimensional space, factorization and searching for a way to express the data in a manner that makes it easier to uncover promising research directions and hypotheses.

Scanning this, it seems the most valuable contribution are their network visualization and exploratory tools. I think they should be proud of those and see no need to stretch so mightily to connect this to Stronger AI. As Vinge notes, "I am suggesting that we recognize that in network and interface research there is something as profound (and potential wild) as Artificial Intelligence."

Interestingly, the University of Virginia recently required all of its students to complete a sexual assault awareness module lasting many hours. (This module had both educational components and survey components.) It likely had a 100% response rate, as failure to complete would lock students out of collab, which is necessary to obtain and submit class assignments.

So UVA is currently compiling what is likely to be a complete and deep set of data, and I am very interested to see what they do with it.
I won't attempt to address this show which I haven't seen, but in general, propaganda can function to normalize or justify the obscene.

Through presenting two sides of an issue, it gives the illusion of honesty or fairness. Even if that strike was represented as a complete mistake with no justification, it has normalized drone strikes simply by exposing them as a thing you witness in sympathy from the comfort of your sofa.
At first I thought they were using some sort of ultrasonic highly-directional speaker, but I suppose inducing currents inside the mic+headphone wire is arguably even sneakier.
That was too indirect. I didn't even think of the connection until you brought it up. It needs to be straightforward. Bad US Government droning the good guys audience symphatizes with. Direct enough that media would call it "controversial".
Fallacy of composition. You're saying that any language with HOFs, immutability and "idiomatic way to contain state" is ergo Haskell-like, which is insane. None of these are even properties of Elixir, but of Erlang, which Elixir inherits. Erlang is self-evidently not Haskell-like. At best such a language would be merely functional. The actor model isn't even about anything analogous to monads, it's a concurrency model that happens to simplify concurrency control through isolation.
I think "nuanced" is the key there.

Also, when you're portraying a minority, the effect of your work will be different. If you live in the US, chances are excellent that you know a variety of white people well. Some are good, some are bad.

Chances are much worse that you know Muslims or Middle Eastern immigrants well. Muslims are one of the most discriminated against minorities in the US, and there's some shocking witch-hunt-esque rhetoric coming from the conservative right that makes it even more problematic.

I'm not saying that a TV show is responsible for righting society's wrongs (or even contradicting stereotypes), but they can certainly make small narrative tweaks to portray people as people, rather than flat stereotypes. It makes the show better, too.
They're both alive and live in with their family (something like their father uncle) in England.

The investigators questioned her for about 30 minutes I recall. Even before her interview they explained that she would probably be of not much help and they didn't want to add to the trauma.

The only thing that got out in the press was that she saw one bad guy (at the time it was thought there was more than one shooter due to the number of shell casings found at the scene).
Superior nuclear capability? (And no, I don't think this sets a great precedent. Then again, it's not really something new to perform war crimes against "3rd world nations" -- but it does seem horribly out of place in our (thankfully) more educated times (as in, all of us are far more educated now, than previously)).

The worst part, is that with all three big players lobbying warheads around in Syria, we might be closer to a third world war than we've ever been before.

I'm 24 and I have never had cable in my life. Frankly, I'm surprised it's not more common. You get a LOT of TV for free. I grew up watching PBS and Simpsons and etc.

I remember at superbowl some of my friends were amazed that I was able to watch the football game without cable. I was floored. They didn't even know that channels came in over the air. I showed them the antenna, where it installs in the TV, how cheap they are. I got HD video without having to pay anything.

These weren't dumb people either. They worked for tech companies. They legitimately did not know it was an option.

A lot of people cut their cables after that party.
Agreed, that is the biggest challenge for them, and the First Data IPO (which is probably the best comp for them) has been challenging.

OTOH Square is on pace to hit $1B revenue / year and growing quickly vs. anybody else in the processing space, but it will all come down to how the market thinks about their business and their ability to cross the chasm from very small merchants (which makes up the majority of their business and they have locked up because other processors / ISOs cannot compete with their customer acquisition costs) into the next tier of small businesses...

Along those lines, great article from Bill Gurley about revenue multiples: http://abovethecrowd.com/2011/05/24/all-revenue-is-not-creat...

Practice is the key. Without practice, even communication isn't easy when you're being judged.

For core or senior engineering roles at big Internet companies, you're generally competing with candidates who have practiced for months. So unless you happen to have an astronomical IQ or you happen to get lucky, it pays to practice.

>the original poster gives a reason he thinks poor people don't exercise (because they are working too hard)

The original poster did not claim that. The poster claimed that they would be restricted in how much energy could be expended elsewhere due to the amount energy expended acquiring income.

Such as? I'm not sure lazy and sloppy are really behaviors or attitudes. They seem to just be your subjective judgement of someone else.

Behaviors and attitudes that encourage poverty are probably those that inhibit learning.
I mean, if we're going to be that vague, we can say the internet is relevant as a discussion topic because Dropbox's business relies on it.

The security of this one feature might be relevant, but the security of the company, especially in the context of a completely separate decision that isn't at all related to this product is, IMO, not relevant here.

My concern is that such a topic is going to dwarf the discussion of this feature, which is really what we should be discussing here. You can already see it happening; the comment thread is the top thread here, and most of the comments on this story are related to it. So while that shows people are interested in that particular topic and its implications, it's also by far dwarfing the real discussion topic for this link, which is the Dropbox Paper product.

How uniform are tech interview questions, in others' experience? I've had questions all over the place, often entirely unrelated to the position at hand.

What is the point of these off the wall questions, and how or should one even prepare for these sorts of things?

You can see for yourself how the US demands from Russia to stop their military campaign in Syria now that the Jihadi groups are losing ground.
