O_DIRECT is not required, as evidenced by many open source databases not using it, but it does enable substantial gains in performance that are not otherwise possible. The caveat is that taking advantage of the O_DIRECT flag, or the equivalent functionality on non-Linux operating systems, requires a couple thousand lines of additional non-trivial code, a subset of which is not particularly portable.

The return on investment is definitely worth it from a performance perspective. However, it makes portability a hassle and implementation requires a high degree of specialized skill, so open source generally avoids it for the sake of easy maintainability.

> The organizers have given an apology to Sarkeesian for allowing a group that has dedicated itself to harassing her over the years

I've looked... is there any proof of this?

- phone calls from those people to Anita

- emails...

- twitter messages

- facebook messages...

If there are, I'll be happy to label them harassers. But until then... I have this weird idea that

the rule of law is more important than feelings

The vidcon people (among others) have made it clear that they will violate their own rules in order to "get" the bad people. People who, according to their own rules, have done nothing wrong.

Witch-hunts end up in one place, and only one place. The people who previously were accusers, on trial, for the same offenses.

So again, is there any reason to believe these accusations? If not, why do you believe them?

Edit Apparently asking for evidence was the wrong thing to do.
I guess it wouldn't be as bad as a separate forum but I'm not sure I see the point either. Who's going to decide which tag goes where? Either the submission is obviously political and you can see from the headline alone or it's kinda-political-but-not-just and in this case where do you draw the line?

Look at the current frontpage for instance:

>Germany bans children's smartwatches

>TechShop shuts down all U.S. locations, declares bankruptcy

>Termination of the certificates business of StartCom

>There’s a Digital Media Crash. But No One Will Say It

>Reddit CEO Cracks Down on Abusive Content to Protect Users, Attract Advertisers

Which ones of these deserve to be tagged "politics"? And for those you'd tag that way, which ones are those you'd consider not part of "core" HN subjects? For instance the smartwatch ban one is objectively political, yet it's probably of interest for the crowd here since it's obviously also about tech.
Do have you have a reason for that?
By the same token it's hard to believe people pushing to raise other people's taxes spent a lot of time considering the morality of their position.
Not being sick after a year is a measurable change, that is unlikely to be placebo. The change is real, even if it would be caused by something else.

But, my primary point was meant to be that the results of the study don't imply placebo, through many comments here throw it around a lot. (I am not sure what kind of effect they would want to see through.)

They do imply that effects are bound to be very small.
Ha, I didn't know that either and I have an eligible card!
The problem is that energy waste isn't a problem to be solved in Bitcoin, it's a feature. So they're wasting energy to farm their Internet Fun Bucks using green power instead of fossil fuels, big deal. It's still energy wasted by design, which IMO is a big part of why Bitcoin is fucking stupid to begin with.

OK. On social issues I support the general liberal consensus. I'm in favor of more financial regulation (although this stance is embraced by both the far left and right), a one payer healthcare system, and free/cheaper access to college education.

Where I differ, I suppose, is against the left's general trend towards censorship, anti-free speech attitudes, anti-police attitudes, and this moral preening about immigration (I believe in borders and the importance of cultural assimilation if you are an immigrant, like I am).
Not entirely true: companies are more than happy to make extremely complicated vesting strategies for their contributions to a 401k just to make sure they can grab back as much as possible just by firing you. The lower and middle class get golden handcuffs. I've known far too many people who've worked miserable jobs far beyond what they should have just to make sure that more of their 401k vests.
I am not changing topics at all. When someone claims that Trump is the worst we have ever had then that of course means we have to compare to what other presidents have done to determine whether this is mostly a disagreement over style or over actual politics.

The Greek island with the key to longevity
With reportable transactions, you can theoretically be taxed whenever the money moves, or whenever it stays in the wrong place for too long. A suitcase of cash only pays the 22% once, and then you can buy as much cocaine and companionship as you like with it, without reporting any of it to the taxman, or filing 1099s on behalf of your grey-market friends, who would otherwise be charging you extra to pay for their sales tax, income tax, FICA, and social security.

Or maybe you just need a quick $100k to keep an ex-lover quiet, but your spouse keeps too sharp an eye on the joint accounts, and you would rather pay extra to not answer any uncomfortable questions.

That's not about the taxes; but about drawing a contrast between services extended to VIPs that are completely unavailable to mundane folk. If I want cash, I have to go somewhere else with a card and push buttons on a machine, which may still charge me $3 for my trouble. And I can only do that if I have already paid all applicable taxes on the money in the account. And I'm pretty sure that if I ever got an actual suitcase of cash from my bank, they would rat me out to the cops before I even touched it, who would then seize it during a pretext traffic stop about 100 m outside the bank parking lot, for their civil forfeiture party fund.
Did you actually read OP at all? Or is it that you just agree with their viewpoint and therefore find the lack of a constructed argument OK? OP has not constructed much of an argument, if anything at all. It is itself a political comment which sparked a shitload of political comments. On Slashdot it'd have received -1 Flamebait.

My simple solution to upvote articles you find interesting stands. That way, you're able to vote on this website, and every unique visitor has a say on the matter here. Its not unique to HN, a lot of websites work like this (Reddit and lobste.rs for example).

Take for example myself. I am not from the USA, so I could say anything related to USA politics or US business or US hiring isn't of my concern. Reality is though that I'm not interested in quantum mechanics. Someone who's a JavaScript developer might not be interested in security. Someone who's interested in UNIX system administration might not be interested about Microsoft Office. And so on, and so forth. And someone who's living in a villa and bought all the villas around him might not be concerned with the privacy of the general population. That's everyone's fair right, and all of these individuals are going to have a certain signal to noise ratio on HN, as well as a vote (as explained above). There is not one single HN visitor who will enjoy each and every article on the FP. And blimey, be thankful of that, because every interesting article which doesn't exist means you got more time for something else.

You can already manually hide articles you are not interested in. Alternatively, if it really bothers you, you could write a simple blacklist with keywords which would then be hidden from the list. But don't make your problem someone else's problem. Don't make it appear that your apathy regarding politics should be the status quo. Just like we're not all into quantum mechanics, some of us are interested in politics.

What certainly doesn't help is complaining about it. Should I complain in threads about quantum mechanics how I find it boring, how I find it a waste of time, and how we shouldn't discuss or upvote it? I'd get grilled. And for good reason. It is disrespectful to those who do find quantum mechanics interesting. So I GTFO of discussions about quantum mechanics because it isn't my league. If you find politics boring, it probably isn't within your league either. So, sure, stay away from it. You got so many tools within grasp to use for that.

>but on the other hand its essentially telling parents that the government knows more about what your kids should and shouldn't wear than you do.

Here in Germany children are not just property of their parents, they are citizens in and of themselves. In this case it is the state's study to uphold their rights, which their parents are apparently not aware of or violating.

The argument that parents are somehow wise elders who know what the best thing is for their children has very little pull here.
>But tags for quick filtering would actually be nice to have. I definitely don't want to read depressing political news while having my morning coffee.

Both tags and better sorts for threads and comments would be ideal. "Ask HN: What tech were you convinced would take the world by storm but didn't?" already had several hundred comments when I first saw it, and it's now at 800. Having the only choices to view that thread be by karma or whatever latest comments appear on /newcomments makes it difficult to browse, although I do appreciate long threads being paginated. This one feature Reddit gets more right than HN.

And to counter the likely argument that adding tags would make the UI noiser, and somehow reduce the intellectual quality of comments by attracting mainstream users, lobste.rs uses tags and they don't seem to have fallen down either slippery slope.

And, HN already has pseudo-tags in the form of "Ask HN", "Show HN", and "Tell HN". Might as well just make those #ask, #show, and #tell and turn the ask and show pages (and maybe jobs) into tag feeds.
I find it really hard to believe you're arguing in good faith. What is the purpose of a comparison to Bush..? Even if the answer is that Bush was worse, it does not take away at all from how terrible Trump has been. And we're comparing 8 yrs of Bush to not even 1 from Trump, here.

Anyway - yes, I do think that conspiring with hostile foreign entities to manipulate voters and undermine American democracy is worse.

Perhaps one of the reasons that a lot of the struggling media outlets are on the progressive end of the spectrum is that they mostly need to be profitable through advertising whereas the conservative side can be run at a loss while their backers recoup their investments through deregulation and tax cuts. If someone could figure out a similar way to profit from Democratic government, that could solve most of the funding problems for those progressive media outlets.

This is anecdotal but I feel it's much more common than we talk about: when I was in ad tech, I saw first hand how advertisers would spend money on impressions for the sole purpose of being able to report to their higher-ups how many impressions and click they got. Particularly for brands where conversion attribution was difficult to impossible.

The media agencies spending on be half of the brand also have virtually no reason to NOT spend ad dollars on fraudulent clicks and impressions - again, they're just trying to get paid.

And of course the publisher doesn't care if the impressions are fraudulent.

Basically, there is a very large rigged economy in ad spending that both sides perpetuate for their own good.

> Shouldn't we first agree on what constitutes racism and misogyny?

I think these are pretty well defined.

Racism: Prejudice against others based on race.

Misogyny: Prejudice against women.

> It's easy to say that others are and forgetting that most people are to some extent.

There's a difference between having a normal level of in-group selection bias and realizing it is wrong, and spouting racist/sexist rhetoric.

> Also because someone in your view is misguided about race or gender does that mean you should treat them as I am assuming you believe they treat people of other race or gender?

No. You still let them speak and vote but you don't listen, and if asked, you tell other people they shouldn't listen. You can refuse to let them use your company to spread their hate.

You have a right to free speech, you don't have a right to someone else's bully pulpit.

The concern that racists are getting oppressed is laughable. I don't understand the mental gymnastics required to justify that thought process.

Phones are not disguising as a device that doesn't capture sound, people are considered aware that phones can communicate. A phone with a special "spy mode" in which it looks like it is turned off but actually is working like one of these watches might trigger the law, since a person seeing it turned off could have a reasonable expectation of not being captured.

You hiding a phone isn't the fault of the product type, and thus only your actions might be illegal, not phones themselves.

Speaking as someone of similar mind, but who has children, it's rather challenging to accomplish when your child's friends and peers are all equipped with such devices _and_ the teachers assume that they are available. It's hard enough on your children to be the odd one out, it's harder still when the teachers are assuming that students are equipped with immediate access to the internet and productivity software.

I wonder what the future is going to look like when analog methods of communication have been eschewed for several generations. Imagine how vulnerable we will be to a massive Carrington event when most of the population is barely capable of (or incapable of) multiplication and division. Antique solar-powered calculators will be back in vogue!

> — its torque is also constant and available from 0 RPM

I don't think torque is constant. The power is constant, and torque gradually decays as RPM increases as per the following equation:

HP = Torque x RPM ÷ 5252

Most 1000 HP drag cars are in their power band from the time the driver lets go of the trans brake until the race is over (unless it's a stick shift, but most drag cars are automatic).

Like any other conventional automatic, there is a torque converter between the engine and the transmission which allows the engine to spin faster than the transmission input shaft.

At the starting line, the driver engages the transmission brake, which locks the transmission and allows him to floor the engine, which brings it up to the optimal RPM (and spools the turbos if so equipped). It's almost the same as if you were to hold the brake and floor the accelerator at a red light. The only difference is that the brakes on a drag car wouldn't be able to hold it back, so they use the transmission instead.

Then, when it's time to start, he lets go of the trans brake and the power is instantly delivered to the wheels.

There usually isn't an issue with not having enough power at the starting line. It's actually the opposite. High power cars usually have to limit their starting RPM to avoid doing a wheelie or losing traction.
What happens when being impartial leads to an appearance of bias?

There was an interesting segment on NPR sometime after Trump won the Republican nomination, looking back on how they had covered Trump during the primaries.

When they got a sense that they had been running more negative things about Trump than they had about the other Republican candidates, or less positive things about him than about the others, they started skipping negative things Trump did or said that would have been top stories if, say, Ted Cruz or Marco Rubio or John Kasich had said or done them, to bring the total number of negative Trump things they ran more in line with the negative things about the others. Same with positive Trump things...they adjusted to keep those at least in the ballpark as those of other candidates.

In retrospect, they realized that they were simply unprepared for a situation where a candidate would have as many negatives compared to others of the same party as Trump had. If they had set some impartial, objective threshold and covered everything from every candidate that crossed that threshold their news segments would have been something like 90% about Trump.

They had implicitly assumed that no candidate would ever be that far out on his party's bell curve, and so killed legitimate, newsworthy stories to try to make the results match that expectation.
i'm not sure they should. perhaps they shouldn't.

Splitting off from that comment, is the matter of reasonable valuations.

Allow me to propose that something like Buzzfeed, with $300 million in expected 2017 sales, is really worth more like $400 to $500 million, less than two times sales. Why? Its future growth rate is likely to diminish going forward with scale (ie its fastest growth days are almost guaranteed to be behind it). Its present growth rate is already down toward 10%-20%. Entities like the NY Times set the ceiling on what Buzzfeed can ever likely hope to be (in terms of business size), and that would be an extraordinary outcome. The NYT is worth $2.8 billion, with $1.5 billion in sales (so less than 2x sales), and has always struggled to have even OK net income margins of 10%.

Buzzfeed was perhaps once worth a reasonably high multiple on sales, back when it had $20 million in sales and a high growth rate. All of these companies have similarly rapidly run out of growth steam: HuffingtonPost, Business Insider, Gawker, Mashable, and so on.

What's a low to medium growth, low max ceiling, low margin, high competition, no-moat business worth? An appropriately low multiple, that's what. Anything else is playing with fire, where you see a $1.5 billion valuation turn into $200 million in a liquidation sale.

The dotcom bubble had a version of this. The Industry Standard was actually highly valued (similar to Mashable's prior $250m valuation) for a brief time back then.

So what's the argument for Buzzfeed being worth a future $5-$10 billion or more (such that a venture capitalist would value it at $1.5 billion in a round)? There's only one argument: another rich person wanting power, narrative control, media influence, and to just generally play in that rich person's sandbox, which is a story that gets repeated over and over again whether it's a traditional tycoon or just a rich venture capitalist. Rich people play in the news & media world like they do in art, swapping the assets around at prices seemingly disconnected from reality, dumping them when times are tough, paying hilariously overpriced rates for them when things are booming.
