Crows have the mobbing behavior when one of them is attacked by a house cat, see: https://www.youtube.com/watch?v=lRdm8JS3qpo

(hours of interesting "cat vs. bear/hawk/crow/snake/alligator/etc." videos available).

Maybe they are responding to a crow immobilized by another creature instead of recognizing a dead one.

>This is the story of all humanity up until the last couple of centuries. Tribes, countries, empires killing and conquering. It's not a uniquely American phenomenon. It's still happening in many places today.

Americans (European settlers that is, but later Americans too) did it in an unprecedented scale -- similarly to European colonialists elsewhere at the same time.

And unlike those older tribes which saw power for what it is, they presumed to have the moral high ground (and/or a "manifest destiny").

How is teacher compensation over there? I always thought we'd see better outcomes in schools if we paid enough for the best and brightest to become teachers.

Fact is, they cannot live in many "reasonably priced" housing markets (let alone the Bay/SF) on a typical teacher salary in the US.
It actually 'hurts' watching people wasting their time with awkwardly slow things on their computers. I keep telling people to use the Home/End keys to jump around in a line, to just hold down Shift for selecting text, pressing Alt to jump/select/delete a whole word, etc. I'm not sure if the average HN reader is aware of these tricks, but a bunch of developers I've met were not until I told them.

I can't watch people clicking the new tab icon, clicking in their URL bar, enter the site name and then switch back to the old site to keep on reading. All it takes is a simple Cmd+L, URL, Cmd+Enter. Same with clicking links.

If you only use your browser twice a day, you probably wouldn't care, but a lot of "tech-savvy" people don't actually have basic skills in using a computer. This is something I hate about today's tech being 'beginner-friendly'. You don't need to know anything about it to use it. I grew up with this, but I still wish people were forced to sit down and learn some basics about Computers, at least how to properly use them, before they could actually use them.
The An Lushan rebellion probably did not wipe out 15% of the world's population. This number comes from comparing before and after census numbers, which is hard because (a) the census was vastly disrupted by the war, and (b) the size of the empire was decreased by the war, so former provinces weren't counted in the later censuses.

Why believe that it takes thousands of years to select and enhance a gene? We have selectively bred animals in decades to exhibit traits that were useful, and long before we had any concept of genetics.

We have evidence of the production of beer dating back before the Pyramids - and beer and wine were staples of pre-modern diets in the old world, that everyone drank, at least in the form of watered wine and small-beer, as the drinking water all-too-often would kill you. Why should we not expect to see genetic adaptation in such an environment?
No, probably more on the scale of months. In my case it was years, but I was an intermittent and resentful user.

I'd say ignore the people who recommend man pages; they're pretty much the worst form of documentation out there. The first thing they show you is a cartesian product of all switches, which can do nothing but serve to confuse you. After that, they list the switches an alphabetical order, which is useful only as a reference after you already understand the command.

It's true, you can search in the man page, but you have to already know the technical term for what you searching for. Your question may be "How can I do X with Y command?" which man pages often don't help.

The are only reference pages for those who already know the commands.

Better ways to learn are to search the internet, specifically the awesome unix.stackexchange.com, and best yet work with someone who knows more than you who wants to help you. At my workplace, there are several Linux experts, and we regularly chat about ways to accomplish our problems in the shell.

Once you learn them, you will enable yourself to do very very powerful things that would take special commands in special apps, which you have to download, install, and perhaps purchase. Such as grepping an entire codebase for a string, as a small example.

Learning a unix shell is like learning a programming language that works on pipes. There is a hump to get over, and once you do, you will be able to express precisely what you want to with your computer. As far as you're concerned, it's the language of the operating system, allowing you absolute control.

Because of my awesome co-workers, I now work daily, productively, in the shell. I use cygwin on windows to develop on remote and virtualized unix environments, and the experience is seamless.

I spent four years growing up in Japan (my parents were ESL teachers) and I attended Japanese public schools for 2nd/3rd grade and sophomore year of college. What the article says is very true; I feel like strangers can be trusted in Japan but not here in NYC. There is strong pressure in Japan to do what's good for others: be clean, be quiet, be honest, be economical. There is also strong pressure to follow the social norm and to not take risks, which affects startup culture in Japan like https://news.ycombinator.com/item?id=8573992 describes well. Both these traits have one thing in common: they point to Japan's exceptionally homogenous culture. I really wish we could have the ubiquitous "care for others" mentality alongside the "be yourself" mentality, but so far I've not seen anywhere that is very much the case. If anyone has seen it I'm really interested to know.
>That stuff happened generations ago so I don't think it's the main reason there is such a drinking problem among Natives today.

Yeah, they are just 1/20th of the numbers they used to be due to ethnic cleansing, having subjected to concentration camps for re-education just a century ago, equally looked down upon as blacks, living deprived from the original lands their culture and society was based on and moved to settlements far away from their homes...

Why wont those fools accept that what's past is past?
Boarding schools and forced adoption weren't was OP mentioned though. What he mentioned was having friends and family killed and land stolen and being forced onto reservations. That stuff hasn't happened in a very long time so I have trouble believing it is the reason for drinking problems.

I agree on the foolishness of grouping all tribes. There are vast range of cultures of varying ages and certainly they have many dissimilarities.

I'm just relating my limited observations in context of two tribes in the SW. In my experience, alcohol does appear to affect the members differently. I don't think its all cultural but does have a biological basis. Just my opinion.
Bernie Sanders has promised everything to everybody. I would say he has the least credibility than any other candidate (and that's saying a lot considering how shitty the lineup is), because at least the other candidates don't make such ridiculous promises like he does... Seriously, how are you going to give people free healthcare, free education, free [insert entitlement program]. His plan of action, "tax the rich more". What a joke.

It has better balance of nutrients. Anyone can throw in some cheap vitamins and call it a day, but having enough potassium (which Americans under-consume compared to sodium), magnesium, protein, is rare. Soylent has 20% of RDA of EVERYTHING. Just check here:

AFAIK in most of the US there are only two cable companies in a given area (both of which typically will be national companies with lobbyists, and also utter shit).

The traditional "telephone" company and the traditional "cable" company, in a given district, each have monopolies that prevent competition.

Since both can now serve cable TV, they only have to compete with one another.

In my area it's Time Warner, which is utter shit, and AT&T.

Anyway, I just don't have cable because they rip you off at best.
Organizing customers against companies that try to exploit their customers is an awesome concept. I suspect it will be a battle, but I wish you success, and hope you earn enough to make the effort worthwhile.

What about expanding this?! Some companies frustrate me with their customer abuses, and you could organize customers against them.

- Cell phone companies send bills that are confusing gibberish so we won't read them. So, provide a service that scans my bill and sends me a readable summary with red-lines on anything surprising or changed.

- Banks and credit card companies send 'privacy statements' that are rambling non-sense. Provide me a service that scans my statements and gives me a nice summary of anything surprising.

- Companies send endless offers for loans or useless services (paper 'spam') mixed in with bills. Filter this out for me.

- Alert me to hidden fees.

- Read the legalese and summarize it.

Basically provide me a service that I will try to accept my bills and statements from monopolistic companies and give me a short, readable, reasonable summary. When something is unreasonable, help me protest or fight it, or find an alternative.

Something like a consumers union, I suppose.
I'd gladly pay well for this.

I can't agree that it's the most horrible worthless thing in the world, having just come out of a relationship. I would have agreed with you prior to that.

I managed to get over it relatively quickly, with several realizations.

The hurt I felt, wasn't that love was lost, but that I no longer had a place for all the love I had. This leads to the understanding that love cannot be lost, it's a resource inside us all, and we just have to find other means to redirect it.

To think of love, from the perspective of a single entity, leads to the kind of thinking of it being worthless. But the shared love that we think of romantically is coming from a multitude of entities, it isn't lost but as a resource redistributed elsewhere.

In death love is truly lost on one side, but is also somewhat immortalized on the other. This solidification of love, is similar to the concept of heartbreak, we don't want to share that love, but the easiest way to free ourselves of the pain is to love.

Love is something you create and give. It can't really be lost, because every day is another day to create or find something to love. You have to separate the concept of love from the entities and relationships.

I still love her, always will, but I had to say goodbye to the friendship because trying to hold onto her was doing exactly what you said. It was killing me, trying to hold on to the relationship, as she started moving on with another. I realized that they deserved a chance, she was chosing to move on with her life and love. That hurt, but what hurt the most was that I couldn't share my love with her any more without possibly alienating him and the love he gave.

I realized those things about love coming from inside and being okay with moving on and focusing on things and others. Accepting that love and care sometimes require sacrifices of ourselves for the good of others.

There is likely a combination of social and genetic factors; while the social factors mentioned in the article affect the rates of alcoholism, there is a significant genetic component, which the article claims has no evidence, but ignores the evidence that exists!

Alcohol metabolism in humans varies among populations, with some having a greater capability to metabolize it. The article fails to even mention the purported genetic causes (lack of ADH or ALDH), which would seem to be important if you are going to claim that the existing evidence is wrong.

That genetics affects rates of alcoholism is not a controversial opinion: the NIH has a report on the variance caused by genetics ( http://pubs.niaaa.nih.gov/publications/arh301/3-4.htm ), noting that "Native Americans and Alaskan Natives are five times more likely than other ethnicities in the United States to die of alcohol-related causes. Native Americans are predisposed to alcoholism because of differences in the way they metabolize alcohol."

This makes sense when you consider the environment of the social sciences today, which favors nurture over nature. Anything that is influenced by social interaction (e.g. stress causing alcoholism) must be caused by it, even if there actually are genetic influences.
Unfortunately, there is a cost to the emphasis on social interaction. Suppose that some people have a genetic predisposition to alcoholism, but they believe that it is caused only by social factors. Then they will be more inclined to put themselves at risk by drinking with friends.

(A similar argument for genetic testing can be made for the APOE gene, which modulates risk of Alzheimer's from drinking. For instance, people with APOE 2/2 are LESS likely to get Alzheimer's if they drink, while those with APOE 4/4 are MORE likely to get Alzheimer's. Claiming that Alzheimer's is caused merely by social interaction while ignoring this genetic effect leads to everyone being worse off).

This is amazing advice and exactly the sort of thing I would forget when I need it. What I need is a guy like you on the payroll to handle crap like this for me. Who is going to remember this website (OP) when time comes to cancel. What you need is a service that is proactive and just handles stuff like this in the background
That's true. I tried a variant where the resampling would be better, but while it is possible, it hurts the compression rate significantly. At the level of a single step: if you have two pixels A and B that are both 8-bit numbers, then if you want some lossless way to store both (A+B)/2 (an 8-bit number) and enough information to restore both A and B, it will take at least one extra bit (9 bits, e.g. to store B and the least significant bit of A+B). So a 24-bit RGB image would become a 27-bit images when interlaced with better resampling (except for the very first pixel, which would need only 24 bits).

In practice, the simplistic resampling is not likely to be an issue -- of course you can create a malicious image which is white on the even rows and black on the odd rows, and then all previews would be black while they should be grey. But most of the actual images are not like that -- e.g. photographs. You can just decode at somewhat higher resolution and scale down from that. (You have to start from a power-of-two scaled image anyway.)
Also note that Y is emitted at more detail earlier than chroma, so most of the error will be in those less important chroma channels. Other than that it's just Adam7 interlacing, but with no upper bound on the number of passes (so you could call it Adam-infinity interlacing).
I think you're right. You too.
This is the same general method as I used to quickly solve "spot-the-difference" games as a child. Just cross your eyes until the images match and let your brain pick out the disparities.

It doesn't have a strong rebuttal, because it doesn't actually have any exact figures.

It has trends which suggest it's of little relevance, sure, but nothing particularly concrete. For all we know the homicide rate in the mid 80s (for example) may have dropped to a historic low without the WoD.

Absolutely. I made some graphs of different kinds of jitter approaches at http://www.awsarchitectureblog.com/2015/03/backoff.html. Simply backing off with delay does very little to spread out spikes of work, and can lead to longer MTTRs if the cause of the issue was overload.

It's funny really. I've never been political until Bernie Sanders has come along, and I believe all of his policies are practical to implement (yes, universal healthcare and free education is easy, stop spending as much on the military as the next top 10 countries combined). I'm volunteering for his campaign, helping with Coders For Sanders, and am maxing out my campaign contributions.

Perhaps its because I've always leaned a bit to the left, and have reached the end of my rope with conservative crazies.
one issue is that veth is slow - slower than VM networking.
in fact since VMs are now booting instantly there's argument to use docker images and boot them as VMs.

I wonder if it would be feasible to have browser functionality that starts the download, then stops it once it has enough data to make an image the width of the element on the page. (Maybe then continuing the download later if it's resized larger?)
That's a great idea unless you run out of addresses or your cloud provider only gives you 8 per VM or you want multitenancy etc.
Wow. Pauline comes across as scummy and Hemingway comes across as weak. I'm not a religious person, but this is exactly what the word "sin" was invented for: an action that is tempting but morally wrong and also makes you worse off.

Like many people, I've been in a similar situation. My girlfriend's "best friend" decided that she wanted me for herself. After a few very unpleasant months of the same "double love" as described in the article, one day me and my gf just decided to cut off the "friend" completely, no contact through any channels. I thought it would hurt, but actually it felt great.
Just joined the Coders For Sanders Slack team today, and I am blown away by the number of fellow tech professionals who've joined. Well done.
>Unfortunately that means exactly nothing. The whole point is that for many (perhaps most) problems, the proportion of hard instances gets vanishingly small, and yet those are the ones that we often need to solve. Showing a sub-exponential trend for randomly chosen instances, or worse, instances he's chosen to show you, is no evidence at all.

I wouldn't say exactly nothing. If no one can present an algorithm than can do at least as good on the same instances...that's interesting.

He did not choose the instances. They were generated using multiple calls to a built-in pseudo-random function. The instances were generated when he requested an instance and the timer started when the instances were transmitted to him. The timer was stopped when a response was received and the response was then verified. He never submitted an incorrect answer.

[Aside: There is a particular web page of a university professor that lists a smallish subset sum problem and claims that the naive algorithm would take some 10^large_number years to find the answer. His algorithm solves that particular instance in some very short period of time (seconds or less I believe). Is that particular instance "hard"? I don't know. Apparently not.

He likes to use that instance as an example of his algorithm solving a "hard" problem. My problem is that I don't know how to verify if an instance is hard (or if such an analysis is even possible/valid). My instincts say that it very much depends on the "density of solutions" in the particular instance. Maybe that instance has lots of solutions and so a random walk will easily find one? On the other hand, maybe there is a limit to the number of solutions that can exist in a well-formed instance?]

While I do not understand his entire proof (and I do believe he has intentionally withheld a portion of the proof [and certainly a key piece of the algorithm (if it exists)]), he does point to some interesting things (such as an apparent fractal pattern in the sum of all sets in the powerset of a set of integers). He claims a function that provides an ordering over the sums of the sets in the powerset, which can apparently be computed on-demand in polynomial time of the original set. A binary search is then applied over the ordering.

In my own theory, it seems like it could be possible; after all, there isn't an exponential number of items, only combinations.

>The whole point

Sorry, the whole point of what? NP-Completeness?
You could certainly build that in as a heuristic similar to how many browsers implement <video>: issue Range requests for a certain chunk size and stop once you have enough data. It's not as efficient as being able to get it all in one go but if you have a progressive image format that might be a better experience if it can start rendering quickly and fill details later.
Even though it is far from ideal, usually we have an agreement, me an Comcast, that the price will stay the same for a whole year (and I still could cancel service at any time with no penalties)
