> escalators just move people within stations, they do not add new routes/destinations and so aren't going to bring people to a station that would otherwise not be there.

They would, if they removed queues. It's not uncommon for people to avoid particular stations because they're often overcrowded, especially if their destination is only slightly further from the previous or next station.

(Transport For London encourage this — the line diagram on Piccadilly Line trains advises against using Covent Garden station in the evening, since it only has lifts, and queues form.)
lol... you don't think engineers are viewed as a cost center? Because they are.
Haha, good one.
Great post, thanks.
Today I also was thinking about how it sucks to getting old. I'm 32 but I see how I'm getting older, my friends getting older and youth looks much brighter :) Value your life and time, young people, enjoy your bodies, don't risk your health, make more love, travel more :)

I don't know why we're so ensconced in Saudi arms. Iran is much more liberal than Saudi Arabia; and Iran doesn't export the fundamentalist interpretation of Islam (Wahabbism) which is causing headaches all over the world.

Now I'll sit back and wait for the "but... but... Iran said they would wipe Israel off the map!!!1!" crowd.
On a more speculative note, regarding Saudi Arabia, this could indirectly lead to the declassification of the full 9/11 report. We know that SA was heavily involved but absolutely could not risk our relationship with them by releasing the full findings.

Perhaps now that we have more options in the Middle East, we can recalibrate towards the truth.

(Left out of original comment because this is wild speculation.)
> Reentrancy is logically weaker than thread safety.

It isn't; neither is an implication of the other. If you mistrust manpages, lookup the definition on Wikipedia.

But in many contexts "reentrant" is the better "thread-safe", as in "what you actually want" (give up mandatory locks to get scalability, composability...).
Or you use floating point textures.
Misleading headline; MSFT simply isn't going to continue any development on previous releases and won't support their use on new hardware platforms. Doesn't mean they won't stop working, just that Redmond won't do anything about incompatibilities.
>IMO, it's a classic case of nut-jobs on both sides of a boarder causing pain for a wide range of people.

I think this is a classic statement meant to be non-controversial enough that everyone can read their own opinion into it, but is inaccurate and adds nothing of substance to the conversation.

Iran didn't become the illiberal theocracy that it is today because of 'nut jobs outside its borders', but because the student revolution that ousted the Shah was co-opted by the hardline clerics, led by Ruhollah Khomeini, who were better organized than the student protestors.

The most reasonable argument for external forces being responsible for Iran's current state as a repressive regime, and as the world's largest state-sponsor of terrorism, is that Khomeini wasn't even inside Iran at the time of the revolution, and swooped in just in time to capitalize on the revolutionary struggle of others.
Lots of people will pick fights with people who have an audience (like pg) just so they can borrow that audience for a short while.

I'm not convinced that most of the aforementioned responses weren't motivated by that. So, given that almost anything pg will write/has written will get the same treatment, why would he play their game by bothering to defend himself?

In fact, there is a pureness to insulating yourself from the cacophony of opinions that you get online: someoen will always have an adversarial opinion and life really is too short to try to address any or even some of them.

It's said that growing up is watching your heroes become human. I'll admit pg was (and still is) one of my heroes and the prime reason I moved across the country to join a startup. While I never got into YC, my (short) life is much better for that move. Yes, the scales dropped from my eyes as I realized just how unglamorous startup life can be and the unfailable pg started to, well, fail.

On the other hand, there's something about the following sidenote that is profoundly human but works quite the opposite of the painful shock implied in my first sentence:

> I chose this example deliberately as a note to self. I get attacked a lot online. People tell the craziest lies about me. And I have so far done a pretty mediocre job of suppressing the natural human inclination to say "Hey, that's not true!"

This is almost universally true. It is incredibly reassuring to know that even the greats struggle with this and antagonists pursue us through all walks of life. I'll admit, I've held back from publishing articles that all of my reviewers liked because I worried about the inevitable negative backlash that comes with standing for anything on the internet. Maybe one day I will publish. If so, this essay helped a great deal in getting me there.

Except that allowing Iran to export even more oil keeps the price of crude down on the floor. Saudi Arabia can't survive oil staying at $30 for the next decade.

So maybe this is an end-run around the Saudis and letting things sort themselves out naturally?
He's also wrong in ways. Bullshit may not 'trick' you, but you may 'buy in to it' and that possibility is not considered in this writing by pg, where he believes that bullshit is either forced on him, or that 'it' somehow tricked him into believing it while not considering that he may be leaving a trail of his own bullshit right behind his self.

> If the escalators are at capacity then the right thing is to build more

This is London we are talking about.

There is often simply no room to just build more escalators.
This depends on the ratio between elevator speed and (elevator speed + walking speed), compared to the density ratio between standers and walkers. I'm not sure what the outcome would be but it may be the case indeed that walker throughput would be less that stander throughput no matter what.
Encryption enforces privacy. In a world with no privacy vulnerable people are easily abused by people in positions of authority. Also note that the legal system is not a perfect mapping to human morality - things that are are legal are not always moral and things that are moral are not always legal. Hence it is dangerous to have a world where right and wrong is determined only by an all-powerful legal system.

In my opinion it is important for society to maintain the privacy that humans have experienced for thousands of years. Remember that mass surveillance of every conversation that you have ever had is new thing. Before the internet society had much more privacy. Encryption is a way to ensure privacy in the internet era.
I would use this video to respond every comment here. But then that would be quite annoying.

Surprisingly high percentage, but I guess in such a relatively large group the negative effect of someone from that group having access to everything isn't as large as it would be in a smaller one.

Do you have any such download comparisons between Flash, asm.js, and WebAssembly? WebAssembly reduces the download size and speeds up the load time versus asm.js. See Unity's testing:

I believe the problem isn't the CPU itself, but drivers for the rest of the platform. Windows 7 doesn't have support for USB 3, I2C, secure boot, I2S audio, and lots of other new technologies. Keeping drivers and BIOS maintained (for what is likely a small number of users) is the problem.

Israel and Iran are far from alike. It's likely true that Iranians are, to our best knowledge, some of the most reasonable and liberal-minded in the Middle East, but Israel does not simply have a "better constitution and governance model". In Iran, the extremists are running the place, and are a large segment of society. In Israel, extremists are marginalized, and even the degree of their extremism is less than that of the Iranian leadership.

I am less welcoming of the news that Iran will be reconnected to SWIFT, as I think that the real good news would be the downfall of the Mullahs and the rise of a representative, reasonable Iranian government, in peace with its neighbours and its own citizens.

This is tangential to your point, but beware of sour grapes. It's an easy trap to fall into.
> Businesses generally get dozens to hundreds of applications for each job posting.

Is it your typical experience as a hiring manager?

My estimate is that on average, number of applications is about 10 per job posting.

Occasionally number of applications could go above 100, but usually it is just a few.

Especially if job posting is for skilled professionals, such as programmers.
Ask HN: Would you use a central DB mgmt Tool (SQL/NoSQL)?
I have been working on a tool that is cross platform and manages SQL databases as well as common NoSQL systems. In the end it will allow you to move data between them seamlessly as well as natively query either without having to leave a single IDE.

Why? Cause my team noticed we were consistently using SQL tools for the data that truly belonged in SQL. But then had to switch and move to NoSQL tools to get data from those systems (and combining them is a bitch). Our idea was to create a single IDE with allowed us to correlate data and to manage data regardless of source.

Is this something you can see value in or is it unique to our needs? The idea is to take what we have done and release it, both as open source and as a licensed product. However, it takes some significant work and dedication to accept supporting others, so I am not sure we should do it. Looking for feedback from the community, thoughts?
I think of this like sticking with RHEL 5 (still supported/updated but barely) and expecting to have full support for modern hardware--don't count on it, and don't expect it to work forever.
Oh, if it was only so easy! There are many other languages which abound with incompetent programmers. Even an atrociously simple languages had many incompetent programmers over the years. On the other hand, there don't seem to be a lot of incompetent Haskell programmers.

It's usually practical reasons which determine the influx of newbies with no previous experience and little incentive to learn to a language. Popularity-wise, C++ was the Java of the 90s, and many programmers came during that time and don't want to learn anything new.
Many other programmers are essentially not willing to learn C++ features beyond the features they're already comfortable with.

"Which features not to use" is another myth propagated by professional C++-bashers. There are very few features in C++ that you shouldn't use, and most of them are officially deprecated parts of the standard library. The real problem is developers who refuse to learn templates, because "void pointers are simpler", or reject std::array, because it's fancy C+11 stuff and writing "char myArray[100]" is much shorter than "std:array<char, 100> myArray;". They then go on to forget std::array ever exist, and complain that vector is too inefficient, so they're going to use C arrays all the way.

If you're willing to use all these newfangled features like closures, initializer lists, 1-part for or constexprs, its' very hard to shoot yourself in the foot. It's very easy to shoot yourself in the foot by using raw C arrays or manual malloc/free though.

"I've noticed that replies to comments marked [flagged] or [deleted] seem to get downvoted more, and am wondering if that's because it isn't obvious that there was a parent comment and it's no longer there."

Definitely. I often find myself doing a bit of a double-take when the topic suddenly shifts, and then I find the little greyed-out "[Deleted]".

Oh, I fell for those sour grapes hard (and might I say, you're absolutely right). It's trivially easy to find "think"pieces supporting any opinion under the sun, making my insistence on declaring grapes sour even easier.

It was used against me at one point, someone invented a personal connection to pg that just so happened to hit all of the right nerves. He was trying to get me to quit my job to work for him. Almost worked, save for a stroke of luck (pg mentioning this guy had ~5% of the credentials he claimed). It's unbelievable just how many bullets I've dodged over the years...
That's not entirely true: http://www.engadget.com/2016/01/11/ford-is-testing-autonomou...
i figure it's not a luxury. people walk slowly inside the stations. escalator or no escalator. platforms are ridiculously small. i avoid taking the underground when i'm commuting to work because it's just hell. walking up the escalator is the one time i feel i'm actually going places (when i'm commuting). this would be acceptable if the rest of the journey wasn't just miserable. now they set out to make the journey 100% miserable. thanks tfl...

why doesn't tfl try and improve the stations instead of coming up with this crap? i hate to sound like some sort of hillbilly but hey, if everyone walks up the escalator the throughput is even greater! another one: if you close down one station for a whole year, why not improve the platforms by making them bigger? in fact, you close down the station for a year and when you open it again the works are not even close to being done! fantastic!

I don't think there's any dishonesty, i think we just like charismatic people more, and are more inclined to believe them. Maybe we don't look quite so hard for cracks in their arguments. Double blind peer review helps combat this, stylized writing helps combat this.

We're just animals. we've got a million subtle biases. I agree with you, we should challenge what we know and believe. That ain't easy.
I was just reading Guns Germs and Steel, and Jared Diamond made a convincing argument that humans are most likely responsible. Wherever humans go, the large megafauna seem to die shortly afterwards. Humans are pretty effective hunters, and hunt in different ways than other animals. Animals evolved to defend themselves from wolves, not spears or being chased off cliffs.

The reason megafauna didn't die off in Africa is because humans evolved alongside them. As humans gradually became better hunters, the animals had time to adapt. But now that humans have guns, and that's starting to change too.

The alternative hypothesis of climate change doesn't really make sense, because there have been many periods of climate change in the past that didn't wipe out all the megafauna.
It's proven (North Korea) that crippling a country's economy does not lead to downfall of its government. I wish it was that simple though!

>Having strong relations with both Shiite and Sunni powers in the Middle East will likely reduce sectarian violence.

This is a ridiculously optimistic, naïve, and shallow reading of the situation.

To better understand the current state of sectarian conflict, I highly recommend reading Kenneth Pollack's recent Brookings essay. [0] To quote:

>Indeed, both the civil wars and the spillover they generate have also produced a general mobilization of the Middle East’s Shiites, instigated and led by Iran. And that includes the Shiites in the Saudi kingdom. Officials in private and press reports occasionally note that hundreds of Saudi security service personnel have been killed and wounded in operations in the Eastern Province, the home to the vast majority of the kingdom’s Shiites. Americans tend not to pay attention to these operations because we see them as proof that the Saudis have things well in hand; but another way to look at it is that the Saudis are fighting pitched battles with someone in the cities of the Eastern Province. In other words, there seems to be a much higher degree of mobilization and violent confrontation among the Saudi Shiites than most realize.

Hear, hear and well said. That inevitable backlash is there indeed and can stymie you out of the gate. The thing is, those who have bold ideas and/or stand for something tend to also be more sensitive to this negativity. I suppose we know that, at the end of the day, our ideas are nothing in a vacuum. As much as we'd like to blaze the trail, we need people to follow or join, not attack and tear down.

Yet, we'd like to think of ourselves as less sensitive, perhaps because we implicitly compare ourselves to the "greats" (if only in belieiving they must have what it takes to achieve what we want to achieve). But, we somehow mythologize that they are above it all, which leads to the mistaken idea that perhaps we don't have what it takes after all.

This was timely for me. A reminder to get my head back in the game, let myself off the hook for feeling the negativity, but to keep pressing forward. Feeling it is not evidence that we are too weak or soft. On the contrary, it means that we care enough about our mission. It should then be worth the inevitable bruises we'll have to take from those who find comfort in the status quo we seek to challenge or who revel in simply demeaning others.

Life is short. So why not do something about that? Are we not meant to be the very essence of creation? Is this not an age of revolutionary progress in biotechnology?

Just this past week I helped out a young company whose founders are working toward clinical translation of a method of clearance of senescent cells, one of the very first actual honest-to-goodness narrow focus rejuvenation therapies to emerge from the labs. This is something that works to repair and reverse a form of tissue damage that contributes to near all age-related disease.

This is far from the only approach to human rejuvenation presently under development.

But, you know, life is short, so pay attention or not, up to you.
At first I thought there was a bug in experiment 2b he writes that the sample space should be:

{'BB/?b', 'BB/b?', 'BG/b?', 'GB/?b'}

Because he describes the event as "He is observed at a time when he is accompanied by one of his children, chosen at random."

I thought he also needed to include two more cases:

{'BB/?b', 'BB/b?', 'BG/b?', 'GB/?b', 'GB/g?', 'BG/?g'}

Which again gives us 1/3 probability of both being boys.

but I guess the part that comes after the '/' indicates the observation event.

Eh, outlandish hypotheses can be worth exploring once they exist as scientific hypotheses, i.e., when there is something that forms a basis for a falsifiable prediction, even if more mundane explanations haven't been rejected.

OTOH, "aliens did it by unknown means" is experimentally undistinguishable from "it happened by unknown mechanisms" more generally, and untestable.

The solution is to actually have a full escalator, with an uninterrupted row of people on the left who are walking. That's what I see in Vancouver, and cities in Japan. The escalator is fully occupied, and one side of it is used for walking.

It's surprising to hear that Londoners are just keeping one side clear, with few "takers" to climb up. Are they unfit or something? Respectful, though.
