PagerDuty (YC S10) needs an extraordinarily capable Senior Frontend Engineer
What bothers me is not incompetent people, but rather incompetent people who don't want to be competent. Like in the beginning (of every skill), I believe that we are all incompetent/naive but as time goes on, you have those who try to advance and develop their skills and those who just don't care. It's the one's that don't care, that bothers me.
Except in this case there is no evolution just different looks. And imho a lot of wasted effort with dubious results.

Big Data Could Sink Europe’s ‘Right to be Forgotten’
great case study of why product design is very hard and requires deep understanding of the factors involved.

as others have pointed out:

- your goal is to clear an area, hence you need a systematic approach to be able to deem a strip of land safe. random paths do not help

- this identifies and detonates in one go. but if the mine does not get triggered, the identifier is lost. these are two separate tasks. merging them would only work with 100% detonation rate.

- this does not work against other types of explosives. anti-vehicle mines, unexploded ordnance, cluster ammo,...

the upside is definitely the low cost. the low effectiveness rate and unreliable pathing makes it lossy though. which with mines is not acceptable.
Quantum cryptography conquers noise problem: Nature news
mad props to you for finding this data and posting it
This article is completely true about traffic driven directly by TechCrunch: lots of users who test, zero retention.

That said there's a slightly more interesting effect to being featured on TechCrunch, and that's what I would call "rebounds": other media noticing your startup / project / whatever and talking about it.

For instance, one week after Moodstocks Notes (a kind of side project / experiment of our B2B image recognition company) was picked up by TC in 2010 (http://techcrunch.com/2010/12/10/moodstocks-notes-is-stickyb...) [1] it got featured in Mashable (http://mashable.com/2010/12/18/moodstocks/). It drove slightly less traffic, but retention was an order of magnitude higher. Smaller, more focused blogs are even better.

That being said, even taking all that into account, fighting to get on TC is probably not worth it. In our case we basically got featured because Michael Arrington noticed us at LeWeb and thought what we were doing was cool, so it did not cost us too much effort. The only negative effect it had was to delude us into thinking we could have unexpected B2C success at hand and divert part of our efforts away from our B2B product, but fortunately that didn't last very long ;)

[1] Yes, I know, this video is terrible. I still can't figure out what happened...
NYC Replaces Public Pay Phones with iPad-like Screens
From your own link:
(b) Any contract or conveyance made in the name of a corporation
which is authorized or ratified by the board, or is done within the
scope of the authority, actual or apparent, conferred by the board or
within the agency power of the officer executing it, except as the
board's authority is limited by law other than this division, binds
the corporation, and the corporation acquires rights thereunder,
whether the contract is executed or wholly or in part executory.

Also
313. Subject to the provisions of subdivision (a) of Section 208,
any note, mortgage, evidence of indebtedness, contract, share
certificate, initial transaction statement or written statement,
conveyance, or other instrument in writing, and any assignment or
endorsement thereof, executed or entered into between any corporation
and any other person, when signed by the chairman of the board, the
president or any vice president and the secretary, any assistant
secretary, the chief financial officer or any assistant treasurer of
such corporation, is not invalidated as to the corporation by any
lack of authority of the signing officers in the absence of actual
knowledge on the part of the other person that the signing officers
had no authority to execute the same.

Obviously that only applies to California, but the first sounds like you only have to verify that the person releasing to you appears to have the authority to do so; the second one specifically mentions vice presidents so it might be best to get a release from that level.

One wrinkle I'm aware of here in the UK is that you can't have a binding contract if one party receives no consideration for it. So you're on much firmer legal ground if you can arrange to pay $1 for your license.

IANAL

Man suspected of wearing 'bomb' watch at airport released, no charges filed
A huge problem is that land mines get unreliable over time and thus a mine flail might hit it but it does not detonate. However it could still go off when handled later.

And there are even mines specifically designed to be resistant to mine flails https://en.wikipedia.org/wiki/MAT/6_mine
But it isn't obvious at all this is happening. The original issue here was a stuck application, and the user didn't know how to get it unstuck. I don't think "do something else for a while, it'll sort itself out" is a good response.
Amazing! Thank you for sharing this.

In practice, scientific software is always work-in-progress in general, people who write it are in many cases novices and software remains unattended after the results have been published. Although scientists should learn to write good programs, we shouldn't expect them to write the best software; a lot of science is not engineering.

One word: Plastics.

He's said this Hyperloop is something that can't crash. If you have something that can't crash you can build it out of plastic which would be much lighter (more efficient/faster/easier to levitate) and cheaper then current high speed rail.

I think is a mag-lev plastic highly aerodynamic train with lots of rail lines so that the cars cant collide.

Ask HN: Please review my startup NameMesh
Hi Everyone,

This is my first review post on HN. I am a recent member and just loving HN.

I recently launched - http://www.namemesh.com and looking for some feedback.

Briefly:
NameMesh is a smart .com domain search engine which quickly creates, ranks and checks names.

It's
1) Complete - checks for lots of things like synonyms, related words, portmanteau, phonetic variations, short url etc.
2) Relevant - ranks all the names based on few metrics. supports ways to do complex queries.
3) Simple & Fast - single step process taking only seconds.

Thanks
Mohit

> Asian culture has been, and is still very much, strongly influenced by the ideas of honor and shame

Regardless, 'follow-the-herd' doesn't neccesarily follow from it. You seem to have very simplistic views of 'asians', who make up many different cultures and people. This kind of generalization is usually a prerequisite of racism - it makes it possible to broadly criticize an entire group of people because of their race and ethnicity.
That would require the developer to rebuild their app with the Google map in there instead of (or as well as) MapKit which, will possible, seems unlikely for most apps.

I suspect there is some interest, but I don't know is the market is big enough to justify creating the materials solely for profit.

As other comments have noted, there are already exhaustive guides on the subject and they are very good. I think the key would be to have a very different approach to it specifically, teach intuitions, not technical details.
Monadic Parsing in C++
Because scientists are aggressively selective in what they read (you have to be, given the volume of text produced) and skip large parts of the paper to see if they're interesting. A very common paper reading approach is:

1. Read abstract. Interesting? Go to 2, else stop reading.
2. Read introduction. Still interesting? Go to 3, else stop reading.
3. Read conclusion. Still interesting? Read the rest of the paper, else stop reading.

The conclusion is there to summarise everything and let people decide whether they want to bother reading the entire thing.
Are you kidding? I love going to conferences and speaking at them! Especially if you do not work in an office, they are a great way to find who is doing what, what's new, where you are behind,nowhere you are in front.

I don't claim any specialist knowledge re:pricing (so bare that in mind while weighing up my response).

I'm not sure about the 1 month trial thing (I think your demo is strong enough that people will understand what your apps about). I get that you want people using it, then when they can't live without hit them up for some money, but you may be cutting your market in half as i'm sure there are a lot of people who travel for 2 weeks who would use your app for that period of time.

As for day-trippers, won't they just use facebook or flickr?
I thought your app was better for proper journeys as you can include elements other than photos (google maps etc).

One last thought: My older relatives always used to make physical scrap books of their travels (with photos / tickets / maps etc) in them. A possible extra/alternative source of income could be to sell the physical version of their online "story" (again not necessarily for them to keep, but to give to other relatives)
I'm just a beginning Ruby on Rails programmer right now, and I would love to start consulting on the side. Not just for the money, but just to gain business savvy. Negotiating and delivering goods is an essential skill I believe a business owner should have.

I think one of the biggest reasons why people hesitate to get into consulting or freelancing work is because the hourly billing makes them nervous. Actually having to record every single hour and recording what they did seems pretty tedious. It's good to hear that weekly billing is considered to be viable because that makes things a lot easier.

I'd love to read that Jeff Bezos essay. A google search didn't find it. Do you have the link to it, or do you remember the title? Thanks.
the problem you're trying to solve is discovering new movies for a user, right? i assume it is, so let me try to expand on why you might have trouble with your current offering:

- some people enjoy movies and are always looking for new stuff.

- their joy is watching movies, not rating them. like / not like right after the movie is ok. some disconnected process is not, this is work, not joy.

- what are the major, simple factors leading to the next good movie?

1., Same personnel involved. director, screenwriter, main actors.

2., I liked their previous work.

3., The major outliers are found by chance or word of mouth. then 1 and 2 are in play.

Now, does a web page solve this nicely? No. Much smarter would something akin to what Netflix is attempting. A XBMC/Plex/VLC plugin maybe that tracks HABITS. No effort involved. The plugin tracks the movie history and maybe, maybe asks at the end if you like the movie.

You can apply the same to songs, etc.

And yes, Netflix, Amazon, all prior art. But actually working.

Convenience is key for consumers. Seamless. Easy. Valuable. Instagram hooked itself into the photo making process. Flickr did not.

Good luck.
1st lesson : stop using language like 'suits'. They are just people with budget to spend on problems they need fixed. The key here is that talking to people is a skill which can be learned. The way to learn is to start, and make some mistakes and learn quickly.

Let's hope Google Maps for iOS will be released soon now.

That's an anti-tank mine. All anti-tank mines are designed to not blow up when people walk on them, only when heavy vehicles drive over them. We're talking about anti-personel mines here.

Still, I agree with your first point.
LinkedIn’s Core Mission: Making Its Profiles The Next-Generation Résumé
The article essentially looks at the distribution of primes modulo a fixed number m (here m=40). Each "ray" of the diagram corresponds to a residue class modulo 40.

As the author observes, if x and m share a common divisor, then there can be at most one prime congruent x modulo m [3]. The interesting classes are those with gcd(x,m) = 1. For those Dirichlet's Theorem on primes in arithmetic progressions [1] tells us that we will in fact find infinitely many primes in these residue classes. More refined, the prime number theorem for arithmetic progressions [2] tells us something about their distribution.

As for the squares of primes: If m = 40 then the residue classes modulo m which will contain infinitely many primes can be represented by:

1, 3, 7, 9, 11, 13, 17, 19, 21, 23, 27, 29, 31, 33, 37

Therefore the only residue classes in which infinitely many square of primes can lie are the squares of these residue classes, which turn out to be represented by 1 and 9 modulo 40 (just square the previous numbers and take remainders of dividing by 40).

This explains why all but finitely many of the squares of primes lie in the two rays corresponding to these residue classes.

[1] https://en.wikipedia.org/wiki/Dirichlet%27s_theorem_on_arith...

[2] https://en.wikipedia.org/wiki/Prime_number_theorem#Prime_num...

[3] Suppose d = gcd(x,m). If y is congruent x mod m, then m divides y-x. Since d therefore divides x and y-x, it divides y. If d is not 1, then y can only be a prime if y=d and d is a prime.

(one more edit): We can also say which classes will contain a single prime and which ones will contain a unique prime square: If p is a prime that has a common divisor with m, then p mod m will contain a single prime (p itself). Then p^2 mod m will contain a single prime square (well, p^2).
In the case m=40, we have that 2 and 5 are the prime divisors of 40. Therefore the residue classes represented by 2 and 5 contain a single prime, and those represented by 4 and 25 contain a single prime square.
2^(40/1.5) is 106528681, just like I posted...

I think the same. For 99% of Ruby programmers speed is bigger issue than monkey patches conflicts.

Sony eats enormous upfront losses to establish its consoles. The PS2 is now the best-selling console of all time, but even with their PSX profits they would've struggled to attract the investment needed to develop it and spend the first few years selling at a loss without the Sony mothership bankrolling them.

Nintendo by contrast makes a profit on every console it sells from day 1. IIRC the Wii is the most popular of the current generation, so I don't think you can dismiss them like that.

I suspect that in a world where console businesses had to stand or fall on their own we'd've seen a less ambitious PS2, with a higher initial price, which would ultimately have attracted fewer developers and been a more modest success. And the PS3 would look a lot more like the Wii in terms of specs and price. How much this would've damaged bluray adoption and HDTV sales is an interesting channel for speculation (and is one of the big reasons sony is happy to subsidize its console division a bit).
I think it's less about corporate vs. non-corporate and more that games are very different from most categories of software. See also the relative success of open source.

You try to unfairly increase the upvotes on your submission, by getting people who don't read HN to register and upvote your submission. Or, you create a bunch of HN accounts, and log into each one and upvote your submission.

Getting on the front page of HN can drive a lot of traffic to a site, which can turn into money, so there's a financial incentive to game the system.
This is a structural feature of modern web entrepreneurship. Through a great new time-saving product with few annoyances at a low price, one builds an audience loyal enough that they can convince investors to hand them lots of money, and then fulfill whatever contractual obligation they've assumed to pound that userbase for more money/eyeballs, driving them away. Sometimes it's not even a matter of additional revenue, but stoking the ego of investors. Google, for example, just removed size from their image search in order to 'simplify the UI' for mobile users who are sexier in terms of plausible growth; This has driven away large numbers of power users, and made it manifestly less useful than Bing.

The average lifespan of a useful tool / company is only a few years; If investors are involved there is always a dark side. Userbase goodwill is a valuable resource will eventually be tapped and depleted.
