Curious, since you seem to have experience with both graph and relational databases (and I have not really worked much with the former)... if I had a graph where I just want to compute the shortest weighted path between two nodes, which model would suit better and how much difference would it make in terms of performance?
How would you suggest it change/whats the biggest problem.

While PGs idea is likely too hard to be doable there is an interesting practical approach with things like Elixir which make multicore fairly easy using functional programming:

"""

Other languages skirt these issues by running on a single CPU with multiple processes to achieve concurrency; however, as Moore's Law pushes us towards increasing multicore CPUs, this approach becomes unmanageable. Elixir's immutable state, Actors, and processes produce a concurrency model that is easy to reason about and allows code to be written distributively without extra fanfare.

I think renting land in any fashion is morally reprehensible. Though I don't fit in with much the neoliberal HN crowd as an anarchist communalist.

Ownership should be restricted to the community of inhabitants of the land. The processes around controlling the land would be voted on democratically, and a federation of community ownerships with local representation would deal with extra-community processes around broader land decision making.

This may be true, but oddly enough it might not really matter. If math such as investigated here is required then those skills can be outsourced to those who are so gifted. The most important thing is the gift of enterprise and entrepreneurship which schools around the world are desperately trying to pick up from the US. Math is great, but ultimately it must be used as a means to some ends and that is where US students continue to excel.
My impression is that Cringely is far more cynical of IBM than others. Still, the outlook for IBM proper doesn't look great. However, as a new grad joining Watson, how do those prospects look? Will IBM's issues effect me even within a division they are heavily investing in? Would love to get some feedback from current/former IBMers.
That's great for you, but it is NOT typical and I suspect that many of the 100 best were private schools.

I've been following CoreOS with great interest, I was just thinking from a security standpoint Joyent's Triton looks amazing... I don't think their pricing is competitive with Google/AWS/Azure though.

Hadn't looked at Atlas... I changed jobs into a larger company, and don't really have to deal with the ops side ever. Though eagerly awaiting a blessed docker based solution to become available in the org... it'll mean that projects can be developed more readily without being limited to the Java based infrastructure in place now.
Just going to point out... Many dead presidents are still spinning in their graves from the day that became a crimp. That's not how the freedoms they strived to uphold are supposed to work.

Single-tracking should have a symmetric effect, i.e. the distribution of delay for both northbound and southbound trains through the track segment containing the bridge repair should both be positive. Instead, the southbound (and to a lesser extent the northbound) trains traveling through the segment actually have "negative delay"--completely inconsistent with the alternative hypothesis. You don't need data science to show that single-tracking doesn't explain the observed data--just common sense.
I'm currently watching The Wire (Season 2). One thing I'm learning is that the common citizen really does not matter at all - the three different branches of the government keep each other in check by alternatively trying to fuck each other over/brownnose each other as much as they can.

That's the genius of checks and balances. As long as no one branch (legislative, judicial, executive) gets the upper hand, we can ensure that the power-hungry people who rise up through the ranks will hold each other accountable, if only for selfish and corrupt reasons.

I'm not sure what to consider corporations though. They seem to have piled up enough legal protection to be considered a fourth, private wing of government. Some of their incentives align (no taxes, bailouts, less regulation) but many more do not. Google and Apple control enough cash and information that they are de facto more powerful than 95% of world governments, and they play a major role in ours. Eric Schmidt taking on a role at the Pentagon is one recent example [1].

As Dostoevsky put it, viper will eat viper. We are all a little Karamazovian - of the black root. It's what keeps the world balanced.

Exactly. I won't have my productivity help hostage to an OS that acts like I should be beholden to it because it was generously forced on my for free.
Awesome! Just a niptick, I think the reaction action should be near where the interface is. So either change the icon to make a reaction to bottom left, or change where it's shown to the right (where milestone, tags, etc are).

This way you get better feedback.
I once had the ambition to teach high school. I'm forever glad I did it, but that experience comprised the 2 most intense years of my life. My experiences in an Ivy League grad school and as professional engineer don't even come close.

I wrote quite a bit in the process: https://alanjayteaching.wordpress.com/?order=asc
That's the point. You shouldn't have to do that. Why should I be forced to expend any energy at all securing myself FROM my OS?

Ask HN: Startup founder seeking guidance
My company is 18 months old and we're ramen profitable ($80K ARR) but aren't growing very quickly and it's becoming more clear it won't grow quickly.

Two questions:

1 - How do I balance losing time on creating a more successful company with learning what is "the startup grind" with my current one?

2 - I'm 23. I don't think I want to start a lifestyle business right now since I want to take risks while I'm young. Is that naive? How should I think about this at my stage in my career?
The responses to this comment seem like everyone took this seriously, but I read it as complete sarcasm.
Yet America, has lead and continues to lead the world.

Maybe we are barking up the wrong tree, maybe school isn't as important for a country as what we take as just fact.
You just told a lot of people that there's no difference between them and a garbagemen. I think you're pushing the point that unless you own a company, you're not "equal" to the people that do (and one assumes you don't mean that employees are better than entrepreneurs).

It doesn't even matter whether you're right or not but you can't attack people's self-worth and expect to be rewarded for it.

Sort of like if I were to say that all company owners and management are fraudulent exploitative criminals.

First job out of college was at JP Morgan treasury division. Was surprised when working on SWIFT system I had read so much about, it was literally just a fax to TIFF system. Basically just an image viewer.

At the time, 10 years ago, we didn't even have ability to parse or OCR the images. I was really disappointed in how low tech this was, and how easy it would have been to make it better.

Perhaps I only saw a piece of it, and it did have more going on. But I always thought "what's preventing someone from faxing in a false trade?" We would execute any trade that got faxed in if the letter head and account numbers looked normal.
This is partially because public schools have to also accommodate kids with disabilities, English learners, and those who simply will never keep up. For these kids, public education is horribly accelerated and they're being left behind.
Ugh, we are a startup, we invested in influxdb on faith that it would "get there", developed around it, and now we can't afford what they want to charge for the scalable version.

Maybe we can avoid clustering with some workaround, (sharding) but I feel tricked.
And when hiring, it's important to avoid hiring folks who think it's appropriate to recount a problem by saying the other person was old, fat, single, and a "miserable neckbeard" before they mention a single word about the problem.

That's poisonous behavior, and if you let that sort of cancer into your company, you won't get it out. Attacking behaviors is great, attacking people is garbage.

You still need to take overall ownership. Get second opinions. Do some research on use that not as the basis of making some sort of self diagnoses, but as to have a frank discourse with your doctor on your condition. Prevent the need for acute treatments by taking preventative measures that have broad scientific consensus (good diet, exercise, safety equipment, etc...). Do you have a living will and advance directives? Check to see if generic prescriptions would save you money. Proactively ask about different drug formulation if you anticipate or identify side-effects. Get justification for suggested remedies. Ensure your records are transferred or up to date when changing providers. Proactively inform your doctor of family history or environmental conditions regardless of any relevancy you expect - let them make the call but give them all the data. Research providers and providers networks, not just for expertise, which is really hard to judge, but for things like: If I call on the weekend who picks up? Your GP on her mobile? Whoever is on-call? A nurse? A referral service from the local hospital? It is wise to outsource expertise you don't have, but not management of that expertise if you can avoid it.
Well, I certainly wouldn't want to start the company that makes the only product that has it as part of its philosophy to make their users learn in order to be able to use it efficiently. That being said you are probably right and the dumbed down UIs we see more and more with low information density are annoying and underline what you are saying. Everything is catering to the lowest common denominator.
any comments on the best football manager games on Android?
Slightly related, but I had a small epiphany when taking a class on DSP on Coursera. The kernel that is used to blur an image and that which is used to remove the treble/high frequencies from an audio sample are identical, except one is in 2 dimensions and the other is in 1. And this makes perfect sense! A low pass filter removes high frequencies, and sharp edges are high frequencies in the 2D plane.

TFA only mentions Gaussian blur, but a Gaussian blur is just a moving average, with "closer" pixels being valued higher, plus a smooth falloff. When you replace each value with an average of its neighborhood, you "soften" the transitions.

I was at a Walgreens a little while ago, and there was a lady buying some sort of cable for a camera. I remember her literally asking the store clerk, "Will this work with a laptop, or does it have to be a computer?"

I bring up this anecdote whenever someone else asserts "<simple technological skill> is common sense, no one could be confused by it".

Help your parents with tech support at least once a year (or your friends' parents if yours are technologically competent). It helps you keep a healthy perspective of how other people see our trade :P

Corporations are part of the checks and balances as well. Most of the opposition to SOPA/PIPA came from the tech industry, they've united to fight the FBI decryption challenge, and they started encrypting everything in response to the NSA revelations. On the flip side, the FTC is continually butting heads with Google over what are acceptable advertising statutes, human rights groups love to expose Apple's use of sweatshops, and European governments are big advocates of privacy.

The genius of democratic capitalism is that it's managed to harness the natural desire of sociopaths to fuck each other over to ensure that life doesn't get too miserable for ordinary people. The unfortunate part is that you pretty much have to become a sociopath to enter the class that gets to decide who gets fucked. But I'd much rather have this than every other social system, where the sociopaths fuck over the common people unchecked.
Here's a historical table of literacy rates:

https://nces.ed.gov/naal/lit_history.asp#attainment

The current estimate is 14% - and it hasn't changed for a decade.

The disparity makes me wonder if the figures are right, but it's nearly impossible to find reliable research on literacy in the US.

You'd think it would be assessed annually, but it isn't. The NAAL data is the most recent definitive survey, and that was done in 2003. I can find one survey since, but the National Institute for Literacy which is quoted in it seems to have closed in 2010.

The fact that there seems to be so little federal interest in rigorously tracking literacy is even more amazing to me than the nominal rate.
No worries, just thought i'd clarify.

I hear this all the time. If it could have been sent overseas, it would have been already.

The reason H1Bs are popular is it allows cheap workers whom can be managed in the US onsite. The management that uses H1Bs doesn't want to move the whole department overseas; if they did, they themselves wouldn't be needed. Executives grow their departments as big as possible as a political goal.

This makes me think Github doesn't get it. Emoji comments are often used because there is no better way to interact with an issue/PR. What we need are better issue management tools. Polls, voting, triage tools, etc. Instead we got an easier way to post emojis. Feels more like a "look we have reactions like slack!!!" gimmick rather than a properly designed response to user requests for features.

Let's say you got a date with a girl. Instead of a date you could have been programming making $100 per hour instead. The date costs you money. Would you outsource the date to your friend who will go in your stead with the girl, so you can be more productive?

No way, the date is worth going in and of itself.

Same logic with raising children.

You're going to to look back on the experience with nothing but fondness. The experience of raising your child was valuable in and of itself.

Life is not about maximising productivity, you know.
As a publicly educated kid from Eastern Europe. We had programming classes as on-school extracurriculars in Pascal when I was 12. In the late 90's.

I once had a "lifeguarding" job that was 20% making sure people didn't drown, 60% janitorial work and pool equipment maintenance with toxic chemicals, and 20% listening to snotty members of the country club say incredibly tone-deaf things. I cried more than once. The life lessons were invaluable.
I don't know why you consider it economically irrational to pay people this way.

And by "appropriate people" I mean if I discover our analog EEs are being paid less than market I bring them up; just because front end javascript jockeys are in demand and their price is going up doesn't imply that marketing people are also underpaid.

You appear from this one message to be extremely cynical. I'm sorry.
I think that teaching your children how to make money while they are still young is one of the most valuable things you can do for them. This, along with the ability to learn independently, will allow them to avoid a lot of misery for the rest of their lives.

There are many people who are doomed to stressful lives living paycheck to paycheck because early in life they didn't learn a lucrative trade and they didn't learn how to learn. Once you are out of school and have a job and maybe a family, just the day-to-day demands of living can drain most of your energy and time.
The best ranked public schools are consistently in the richest neighborhoods, and the worst ranked ones are consistently in the poorest neighborhoods. I don't think this can be disputed. So, what's more likely?

1. Rich neighborhoods result in well-funded schools with the resources to provide a superior education, better than the not-well-funded schools that are in poor neighborhoods.

Or

2. A superior education comes from "children's efforts" and kids that put in a lot of effort coincidentally all live in the same school districts, which also coincidentally are located in the richest neighborhoods?

How big data is unfair
More quotes from the same piece: "The wife is like the fire, or to put things in their proper proportion, the fire is like the wife. Like the fire, the woman is expected to cook: not to excel in cooking, but to cook; to cook better than her husband who is earning the coke by lecturing on botany or breaking stones. Like the fire, the woman is expected to tell tales to the children, not original and artistic tales, but tales--better tales than would probably be told by a first-class cook. Like the fire, the woman is expected to illuminate and ventilate, not by the most startling revelations or the wildest winds of thought, but better than a man can do it after breaking stones or lecturing. But she cannot be expected to endure anything like this universal duty if she is also to endure the direct cruelty of competitive or bureaucratic toil. Woman must be a cook, but not a competitive cook; a school mistress, but not a competitive schoolmistress; a house-decorator but not a competitive house-decorator; a dressmaker, but not a competitive dressmaker. She should have not one trade but twenty hobbies; she, unlike the man, may develop all her second bests."

Thank God I don't have to maintain the bold equilibrium of inferiorities and develop my second bests. Instead I get to do some math -- I am so blessed, although Chesterton would not agree!
Even if we don't produce smaller circuits, we still might produce cheaper ones. There is still plenty of room to go to reduce fab costs. Especially since we basically replace them every few years. Consider if intel solely spent time iterating on cost. We also have made headway on power-reduction. I could see further improvements there. In aggregate I could imagine even if we don't see greater chip density we could see, say, AWS compute power/cost continuing Moore's trend for some time.
Hey I am sorry if you are impacted by downsizing, but there are better ways of handling this than disparaging the tech community in India. I have worked in both US and India for more than one company and can tell you there is no discernible difference in the quality of the work that gets done between US and India. And even if I take your point that IBM are fools who doesn't know what they are doing, how to you explain Amazon, Microsoft and Google hiring thousands of developers in India. Microsoft's largest developer shop outside US is in India. Your experience can be due to a variety of different things from person at the other end doing exactly what he is supposed to do just to not poke holes in a secure infra to assuming that the firewall access list is state-full and allows return (HTTP response) traffic to pass by default. And there is no guarantee that a person based in US won't do the same thing.
This is very true. If you are a developer or a designer, I highly recommend you go to the Apple store and hang out for a few hours by the Genius Bar. It is eye opening to see the questions that people ask. I have a lot of respect for Genius Bar employees who calmly explain how to use email, their iPhone, or their laptops. You learn so much about UX and user's thinking by spending some time there.
