>And honestly, the fact you think this "ultimately caters to a tiny fraction of gamers while worsening the experience for the majority" tells me you're part of the problem; you're probably often toxic to other players (even if you don't notice it), get your account muted/locked out/whatever, and then think that you did nothing wrong and everyone's in the same boat as you.

Sorry for having the wrong opinion, but personal attacks are uncalled for.

Ironic.

So, to illustrate my point, would you prefer that heavy handed mods step in to censor you according to their definition of toxicity, or would you rather have the freedom to continue this discussion to possibly reach some resolution?

I prefer to put faith in peoples' ability to resolve conflict without vague rules regarding inconsistent notions of toxicity, especially in the context of gaming, where I can leave and join another game more or less any time.
When I was an exchange student I had a Mexican friend from Puebla and one from... some small place near the north of Mexico, forgot which one.

They cannot see eye-to-eye over whether burritos are "real" Mexican food. Obviously, being the good friend I am, I liked to poke and prod this.

Ask HN: As freelancers/consultants, what tools do you use to run your business?
Hey HN,

I'm a product/marketing consultant, working with several companies at a time. I'm having a hard time keeping track of tasks, billable hours, invoices and the like. Project management tools are often geared at teams trying to work together, and so have bloat I don't need (stuff like chat and forums) and don't have some things that I do (invoices, time tracking). I'm sure people have built tools to make running business like mine easier - do you know of any?

Thank you!
I'm not sure this is just IBM lacking the vision to see their older employees for the value that they truly hold, rather, they're just following the path of least resistance. I see this same sort of scenario playing out in other companies across the globe too; why should any company be innovative enough to value and empower older workers when they can just exploit young, naive talent?

How do we prevent this exact same vicious cycle from playing out all over again in 25-30 years when Millennials are the grey-haired ones with an inability to "innovate" or "connect" with the younger generation? If anything, with the rapid pace of technology only accelerating over time, future generations will become irrelevant "old heads" on an even shorter timeline.
I wanted to remove facebook, but i can't I will lose connections to friends I met outside my home country. Its kind of the internal person-service that i can't live without currently.
It's almost like knowledge is power or something.
Thanks a lot for sharing, I enjoyed reading this.

I spent most of my life in Texas and went to college in Austin. The first thing out of my mouth when I get home: "let's go grab some Mexican." I can't think of anyone (friends and family living outside of Texas) that doesn't do the same -- Tex-Mex will never be killed :)
Freenode's nice!
I realize the self-driving/lidar/AI/IR is more interesting to the HN audience but what about the pedestrian? How can the pedestrian not see, anticipate and react to a 4000 pound SUV, on the road (where cars normally are), with headlights (I assume they were on), driving right towards her?

Did the pedestrian not look both ways? The pedestrian could have easily gone to the crosswalk, waited a few seconds for the car to pass and then jay-walked, at least stopped in the left lane when they realized the car wasn't slowing down, hurried to get across,
or something.

Based on the video it looks like the pedestrian was just as clueless as the "driver", only looking up in surprise at the last second and making no move to avoid the collision. Maybe it sounds cruel blaming the person that died but they certainly played the largest part in their death.

I am making no excuse for Uber, I know nothing about self driving cars or the tech behind them. But come on- how can a 150 pounds person walk into the middle of a road without making any effort to check for their own safety? It seems similar to stories of people wearing headphones and walking down the middle of a train track.

As a 200 pound ball of squishy flesh and my life on the line, I feel it is my job to be very aware, very cautious, very careful when entering the domain of 2 ton speeding metal objects, especially in the dark.
Because the more mainstream it is, the less control the "they" (insert correct term here--damned if I know who "they" are but I am certain there is a "they" that desire servitude from as many people as possible because that's the game) have over us.

Knowledge used to be something kept fairly secret because in the past it was hard to research how to do and make things. I used to have a lot of trouble finding information about my cars in order to work on them. The same experience repeats--you had to be in a club with like-minded people to bootstrap knowledge and people held on to manuals and homebrew documents created on a typewriter with annotations in the margins. Now all that knowledge has been dumped onto the Internet and is easy to find and videos make it fast to pick up.

The problem with being in a club is that most of the personalities don't mix but the club controls the gateway to the knowledge. For a long, long time, gun clubs were loaded with Elmer Fudd types who looked down their noses and modern semi-automatic rifles and handguns. They only accepted typical hunting rifles and shotguns, the odd Browning semi-auto, maybe an M1 Garand or M1 Carbine for WWI and WII nostalgia, and of course, the cult of the 1911. But they didn't understand the 2nd Amendment, not like many of us do now. Because they didn't need to--there weren't vast armies of thug leftists trying to bludgeon the nation into some form of corporate collectivism.

What has changed is manufacturing technology, not the guns themselves. Things have changed quite remarkably and those old ideas are disappearing, which is mostly good. What isn't good is that the knowledge, information, and yes we have the best selection of small arms in 150 years, is available to all at affordable prices. A few outliers are having problems dealing with the responsibility of it all. But we as a society can't cater to the least common denominator. We have laws to deal with criminality but lack the will to do so--hence why the Broward deputies didn't arrest that wacko during one of the 40 some times they were in contact with him. Either they directly desired his violent outburst for political reasons, or they were just too politically correct to act. Regardless of the details of each incident, we have a remedy in law and that is to punish the guilty and stoically move on. If the sheriff were to lose his job for being incompetent, all the better.

Firearms are just one teeny part of what it takes to stop the oligarchy. Humans tipped the balance once before: When guns were invented and first arrived in Europe, commoners made good use of them shooting armored noblemen right off the backs of their horses because screw those guys. The scientific revolution being the direct result of the end of medieval period. We all owe a lot to firearms, they are the necessary evil for humanity.
Chronic fatigue trial results 'not robust', new study says
Yea I don't see this working.

For starters the problem isn't the games, or the enforcement mechanisms, it's the gamers. There are plenty of other competitive activities with "randoms" that do not result in this type of behavior.

Another issue is that there will be those that get punished/removed that will play the victim and attribute it to politics, etc. You can see this beginning already in some of the comments in this thread about "dictating morality" and "silencing non-progressive behavior."
It's much more than that. What if the next time someone posted a conspiracy theory on Reddit about Hilary Clinton she filed a libel claim against Reddit in the UK.

The UK court will consider that under it's jurisdiction because the publication was available in the UK. The UK libel law essentially puts the burden of proof on the defendant.

So now an American citizen can force an American company to prove that the claims of an anonymous user were true, or pay damages.

You can't IPO if everything on your platform is a potentially bankrupting libel lawsuit waiting to happen.

Dude, you are insufferable. Quit being so pretentious and passive aggressive, and you won't have to nuke your HN account every few months and start fresh.
For a walk.
A lot of people have good input here already, so I'll offer a more "organic" response.

Keep it simple- to improve your public speaking skill, there are 2 main ways. #1, do more public speaking! #2: listen more.

Obviously, the more you do something with a mindset of growth, you usually get better at it. However, if you want to get really good, study other talks/events/conferences etc. Pick ones that are extraordinary, and study their talk- listen and watch.

What's the flow? How do they link ideas? How do they keep the audience engaged? How does the audience react to what they say and do?

I recently had the opportunity to speak to a friend who is an amazing speaker. He told me about how he would prepare his talks, how he would time himself and practice over and over. He would link ideas in his mind, and lay it out strategically.

One thing he said stood out- he watched the response of the audience. When he would study other talks, and people would say "hmm", he would write down what the speaker said. He trained himself to become an amazing listener- to hear what was said, as well as what wasn't said, but still communicated.

If you wanna get better at public speaking, do it more. If you want to be an amazing public speaker, listen more.
As a resident of Dallas, thanks for this :) Looking forward to trying the recipes.
In addition to the other replies, I think one aspect people are ignoring is the "bias" of timing. The previous election occurred ~6 months prior to Edward Snowden's leaks. I think that was an inflection point in the US for the public and their perception of online data collection efforts. The Cambridge Analytica story is coming after 5 years of increasingly worsening public perception of personal data collection, privacy invasion, and digital surveillance. Prior to Snowden I don't think the majority of Americans understood the scope of the amount of data being collected on them, and what could be done with it.

The field of "data science" hadn't become quite as mainstream in 2012. These days you can't take 2 steps without tripping over articles about analytics, artificial intelligence, or machine learning.

Public perception of Silicon Valley has soured quite a bit during that time as well. Facebook, Twitter, Google, etc. were all probably at the apex of their positive public images. I suspect that the average article regarding Silicon Valley from 2012 was much more positive than what you see these days.

In short, I don't think the contrasting narratives are as much do to with media bias regarding Obama vs. Trump as they do with major shifts in society from 2012 to 2018.
Fast and accurate view classification of echocardiograms using deep learning
I still see ads on reddit for alcohol and tobacco products (well, I did until yesterday when I turned uBlock back on for reddit). A subreddit that links to wine for sale is bad, but if those same links are purchased as ads it's allowed. I think that says a lot about the morals behind this change.
> Did schools stop offering programming classes?

Yeah, pretty much. My high school nixed their programming and other CS-related classes while I was a sophomore. This was 2001. Probably a terrible move, but they did it anyway. I assume they've wisely brought them back by now.
WhatsApp

You know that's still Facebook, rrriiiight?
Google's core business is advertising, and advertising is likely also considered 'content' in this context.
Sadly, at least in the U.S. it is normal for many professional women to feel like they need to dye their hair. It is part of the general U.S. cultural bias toward youth in women, which is pretty obvious in popular media but also makes itself felt in the workforce.

Grey hairs can start showing up as early as late 20s for some people. I work with a number of women over 35 and I'm having a hard time thinking of one with a single grey hair showing. For a few I'm friends with, I know that dyeing their hair feels like an important part of maintaining their professional appearance.

Even Ginni Rommetty, CEO of IBM, probably dyes her hair. She has blonde hair without a strand of grey showing, which would be pretty extraordinary for someone who is 60.
Applying Topological Data Analysis to Alternative Data via Hyperspectral Imaging
This is terrible advice even for the tiny fraction of people who can actually follow it.
At this point, I think it is unproductive to comment on Zuckerberg as an individual (ad-hominem attacks?) because this leads to assuming that any alternative CEO would be better. I don't think we've had any solid evidence so far that he's naïve or a "sleazebag". However, what might be more frightening is the fact that he appears to be very normal and that many of us might share more traits with him than we'd be comfortable with admitting. Or perhaps that isn't frightening for many, and he is who some still aspire to (just like how many admire the management style of Torvalds or Jobs).

Facebook's business model doesn't depend on Mark Zuckerberg's "magic". It will continue to grow or break regardless of whether he's at the helm or not. Users, advertisers, competitors and governments will have to be the ones to decide.
How would he have lost everything? The pension would stay no matter what.
Strava became my FB substitute, oddly enough. It's the only social network I really like and wish I could spend more time on.
Can't you ask them for alternative contacts?
In places where housing was affordable, especially ten years ago, no... you wouldn't necessarily have wanted to enroll your kids in the public school where you lived.

I was in SF when my child was young, but as soon as we started digging into the school enrollment processes, I moved to Lafayette and enrolled him there.

Lafayette was more expensive than Union City, but a better place to live and school, but perhaps not a place where a house could be as affordable.

That said, none of it would compare with a 32 acre farm near Vancouver, IMHO...
I'm sorry that this news isnt trending in HN.

"The market can stay irrational longer than you can stay solvent." -- Schilling.

And when that irrationality is not just stupid, but also unjust, then we should not put the burden of such stupidity on the victims of the injustice.
It might seem counterintuitive for the reason you described, but the problem with water and ground bursts, is that the entirety of the radioactive byproducts interact with large amounts of dense material. I’m a true airbursrs, the fireball doesn’t touch the ground, so the air itself is contaminated, along with material from the ground which is drawn up into the fireball through convention and blast effects. That’s still dirty, and in the case of the Tsar Bomba (50MT) catastrophically dirty. The total volume of affected material though is relatively low.

If you detonate underwater, all of fission byproducts, and unburned fuel comes into direct and prolonged contact with a large volume of dense material. In a shallow blast, gigstons of thst material are ejected into the atmosphere, while the rest remains underwater. It will be diluted, it a 100MT device is still going to produce horrendous and long-lasting effects.

That material will poison the underwater environment as it settles in the immediate area, and for km away as it dissipates. Worse, it will enter the food chain and be concentrated through progressive predation.

This covers the explosive (not radiological) effects of non-airbursts for some context! http://www.abomb1.org/nukeffct/enw77b2.html

Also, number triads ending in 1 or 11 smaller than 80 need an 'and' conjunction. And numbers ending in 1 need to concord in gender. What a mess.

Before the 1990s there were also all sort of over-complicated hyphen rules. Thank god it's now simpler; hyphens everywhere.
You can always send them a message asking for their email addresses or phone numbers before deleting your account.
Just call it a gut feeling, but I don't think he will be criticized as a foreigner buying property in Canada and employing a loophole to gain entry (ie creating a company to sponsor his work visa).
I think the said the "solution is", it does not matter if the functionality exist today. Its more of how the gaming industry should handle these situations. Simply blocking somebody should make it so you can't ever be matched with, or have to communicate with them again.

In some games that might be harder said then done, but you could at least make sure you are never on the same team, and that if the player becomes an opponent that its name is obfuscated and they can't chat back.

Now it is network effects. But when it first started it became popular because:

a) MySpace wasn't actually that popular (was your mum on it for example?) so there weren't many network effects.

b) It looked clean, unlike the eye-stabbing experience of MySpace

c) It was more secure than MySpace because only people from your university could see your profile.

Things are different now so you're never going to have success with that strategy (although the university-based access thing could potentially work again).

I think what will kill Facebook now is the sheer volume of low quality content on it - not just adverts but "Dave tagged you in this meme", and "Jen shared this gif of a cute dog" and "Remember what you were doing one year ago today!".

It's just, not very pleasant. You can tame it by using an ad blocker and unsubscribing from most of your friends... but even then there are some post types you can only "See less of" (yeah right), and it's .. just... crap.

This privacy thing is bullshit. It was an obvious problem in 2012 and nobody quit over it then. They removed the API in 2015. Why would people quit now?
How to make sure your Drupal website is secure
I guess, to xenophobes, everything looks xenophobic. Sure, there are national security threats from many other foreign actors, but in this particular case, the poster to whom I responded wants to specifically discuss hypothetical threats posed by Chinese interests and companies that are geo-politically close to China.
Writing and publishing a recipe is absolutely protected by the First Amendment as an inalienable right.
That's true. But there are two big reasons why we hold governments to those standards: they hold significant lethal power in enforcing their policies, and they have no competition in their domain.

Corporations absolutely quality for one of those. If every game manufacturer starts enforcing draconian free speech rules, players have no recourse beside "don't play". That's an option. If it gets bad enough, hopefully "good business" kicks in and they pull back.

The big problem is the reasoning behind why these policies are in place. They aren't really doing it because they think it'll lead to better business; these games are already ridiculously popular, and are approaching the carrying capacity of their respective markets.

Instead, they're implementing them because they think its the morally correct thing to do. That's a very dangerous road to go down, because its politically very hard to reverse a policy like this. Once you start restricting what people can say under the guise of something as buzzwordy and pure as "preventing toxic behavior", no one will be "that guy" who says "we're losing business because people are afraid to even speak, we should pull back". All it takes is one softer soul to call that person a bigot or an enabler of toxic behavior, and they're fired.

I worry about platforms like Twitch, where "twitch chat" has become such a meme that it almost defines the platform. Its not about whether that definition is good or bad; its about trying to fundamentally change who you are. YouTube tried it with their comments section. No good discussion ever happens there. Not before their change, not after. But at least before it was fun and people used it. In essence, they destroyed legitimate business value in the pursuit of perceived business value based on moral righteousness, that perceived business value was never realized, and now they can't go back.
