> I asked Kappes why fantasies hamper progress, and she told me that they dull the will to succeed: “Imagining a positive outcome conveys the sense that you’re approaching your goals, which takes the edge off the need to achieve.”

This is a massive oversimplification. I know many, many people, including myself, for whom imagining positive outcomes feeds a chain reaction of emotion and motivation which drives us to try things within and beyond our reach and ultimately to come out on top even in the face of numerous failures.

Of course, as posters like theorique point out, it is not enough to merely fantasize. The positive fantasizing must, and will, motivate one to build successful habits. It is not enough to distract ones' self with a utopian mirage. It is necessary to include details and additional questions in the fantasy, such as "back from the future thinking." e.g. "Ok, my startup is successful, who are my customers? Who are they servicing? Which features of what I'm doing/did got me there?"

And I believe doomsayers like the authors of this paper and this article know it damn well. There's just a more comfortable place for them in the larger cultural climate to negatively criticize the author of The Secret than there is in clarifying it. For the authors of the paper, there is more academic capital in running a "computerized content analysis" than there is to actually produce any results that help anyone.

Furthermore the abstract of the Oettingen paper suggests serious misunderstandings of finance (1. Just b/c DJIA goes down doesn't mean the economy is bad. 2. The measurements were made during a financial crisis) and correlation vs. causation.

So, fuck this article! Go out and do something awesome and visualize the shit out of it!!!!!!
We have; here's an example. A solar panel in geostationary orbit only has a few hours of shadow per year. The incoming power is so much greater than that at the surface (about 4x the best desert) that a solar array in space will have a positive energy balance even when launched with current rockets. With a space elevator, orbital solar might be the most lucrative source of electricity. http://physics.ucsd.edu/do-the-math/2012/03/space-based-sola...
AFAIK the Shannon limit applies to a channel with a single transmit antenna and a single receive antenna. MIMO can get a factor of N more throughput without breaking Shannon by using N antennas.

Yes. This. Having had FiOS before is the worst part, knowing first-hand just how subpar my TWC service is (there's no going back after getting 35mbps upload speeds). It seems completely ridiculous to me that in 2014 Brooklyn we're still choosing block-by-block where to live based on the internet service.

It always surprises me how excited people get about Google Fiber, yet how up-in-arms they get about GMail, Google+ and other Google services which tend to invade and/or expose your privacy. Do you really think that using a advertising company's fiber as your gateway to the internet is going to offer a private experience? Don't you see how much easier it will make it for them to gather your personal details and habits? Do you really think Google won't use your data to their advantage?

From (http://en.wikipedia.org/wiki/James_Stockdale)

When [...] asked who didn't make it out of Vietnam, Stockdale replied:

Oh, that's easy, the optimists. Oh, they were the ones who said, 'We're going to be out by Christmas.' And Christmas would come, and Christmas would go. Then they'd say, 'We're going to be out by Easter.' And Easter would come, and Easter would go. And then Thanksgiving, and then it would be Christmas again. And they died of a broken heart."

Stockdale then added:
This is a very important lesson. You must never confuse faith that you will prevail in the end—which you can never afford to lose—with the discipline to confront the most brutal facts of your current reality, whatever they might be.
They didn't develop them in parallel. One programmer took it upon himself alone, and without telling Apple, to do the initial port to x86.[1]

Google Fiber will pass <~0.5% of total U.S. homes[0], even after they build out Austin and take over Provo. They have to start doing things much faster if they will make a dent this decade. Google is selectively building out 'fiber hoods' - neighborhoods that bend over backwards to get the service, pre commit and make construction super easy - not full cities, by any means.

Google Fiber was announced almost four years ago and has only a few tens of thousands of subscribers. While it's fun to get excited about what Google Fiber could be, it will be years before any material percentage of the country has the opportunity to use Google Fiber.

Google is still building out small neighborhoods in Kansas City [1]

The beamforming means that each channel can use less power and get a higher SNR. Thinking of aimed signals as a single wire is wrong. The hardware analogy is a single wire in a highly-directional antenna aimed at each client. There's no real sharing of spectrum. The only difference is that you can use software plus 100 undirected antennas to simulate having directed antennas.

I'd argue the best way to stop thinking about something, is to divert your mental focus to other thing/s intentionally.

I seem to recall reading on Ars Technica a summary of a study that found that, in a controlled experiment, those who tried to stop thinking about something by directly shutting it down were more successful than those who tried to replace the thought with a different thought.
Why does "Twitch Plays Pokemon" Work? – My Musings
Yes, every major ISP has bandwidth caps, some of which are prohibitively small (20GB). Even the smaller upstart ISPs, like TekSavvy are forced to have a cap (though at 300GB) due to wholesale laws. At least they offer unlimited for a reasonable amount of money.

Canada is definitely behind the US for internet access, it's even behind many (if not most) third world countries.
I believe so - I have to use a relatively small player that resells Bell infrastructure.

The way it works is pick any two of speed, capped usage or reasonable price, but then forget the last one because it doesn't exist anywhere.

I consider my, still expensive, 4G mobile way better value than the land line ISP, but I need the capacity for work. Frankly I think 4G is going to wipe out land lines in far more cases than people realise.
I wish they'll come to Santa Barbara so badly (As I'm sure everyone also does for their cities). We do have lots of tech here and even good connections to Google, but I feel we're probably too small. Even Verizon pulled out from installing FiOS.
There may be a technical differences between bad network performance due to some active throttling configuration in the network hardware, and bad network performance because a company doesn't want to make changes to a network interconnect. To the end user sees both cases as "throttling" in terms of poor performance.

Net Neutrality should be about how we come to terms with companies that are pure ISPs trying to deliver data their customers want vs companies that stand to increase profits and hurt competitors through active throttling or, in the peering case, simple inaction.

> We were running out of file handles which caused the database to crash

Most distributions ship with conservative defaults for the maximum number of concurrent file descriptors and socket connections. Especially for a database server, it's wise to tune these values before optimizing anything else.

> 1000 files per connection * 370 = 370,000 files

This is a very pessimistic estimate, in reality you'll need much less than 1000 file descriptors per connection. As long as you tune your file descriptor limit, you should be able to handle one or two orders of magnitude more connections than this.

I won't argue with your point re: web apps being pedestrian. I'd be the first to agree, if it isn't obvious. I have multiple comments here on HN where I scarcely hide my negative view of the pervasive fad-hopping "rockstar" macbook wielding silliness that seems to suffuse certain segments of the Valley.

My point wasn't that you won't be able to hire developers adequate to the tasks you require. It was that your target labor pool doesn't intersect with the labor pool target of companies building "database engines" or scaling up to "billions" of users, and so to compare your compensation packages to companies who are looking for engineers capable of building those things is a bit daft.

So, to me, proofs have two purposes. The first is to just say "This theorem is true". The second is to give some insight into the problem. I have no problem with such a proof satisfying purpose one; I may not be able to check it myself, but I can build a chain of trustworthiness all the way back to a program that I can check myself. In such a chain, the truth of the final result is not, to me, in dispute.

Alas, such a proof throughly fails the second test. I can't see how to gain insight into the problem from such a proof, beyond just it validating previous thought chains of the form "If X were true, then I could deduce Y". It doesn't reveal more about the structure of the problem, or other results in the space.

It's no doubt useful (and all credit to the authors), but in terms of generating new mathematics, I'm dubious. Perhaps people more versed in this specific sub-field can tell me if I'm wrong?
Lispmachines existed in the early days of C, so no probably not.
Hello there, I am Thomas, one of the guys involved in the development of aquard.io. The fish are real and the feeding is FCFS (first came - first served) based. We designed the logic based on an estimate of ~50 concurent users. So it does not work well (for interactions) when massive users are online. 300 Users to One Physical Object :/. Feel free to ask me anything related to the project and from the side of the team thanks for enjoying it!
In a non-cynical mode:

1) turns your employees into neighbours

2) reduces wasted commute time

3) increases exercise compared to drivers (10 mins is better than nothing (edit: twice a day!)) thus reducing medical costs

4) reduces absenteeism due to dental appointments, kid concerts, etc that tend to be near home. Improves family life.

5) reduces the carbon footprint of the business

6) reduces the car-related absenteeism: breakdowns, maintenance appointments, even injuries and deaths.

Increasing salaries would do none of these things.
The Definitive Professional Publishing Platform
That sounds strange to me. I live in Sweden and went apartment-hunting last year. Not one of the apartments I looked at was without fiber (technically, ethernet in the apartments, fiber to the building). Including buildings that pre-date WW1. They all had pre-existing cable and DSL as well. If there's a will, there's a way. I guess in the US there just isn't much of a will yet.
Segment.io is looking for a lead platform engineer
Segment.io lets companies integrate with over a hundred analytics tools with the flick of a switch, and we've only just started. We're looking for an engineer who is extremely organized, who loves talking to customers, and who is interested in managing all of the integrations on our platform.

We add over five new integrations a week, and we don't see that slowing down any time soon. We form partnerships with almost all of the companies we integrate with, so that we can streamline the entire process for our customers. The awesome part is that as soon as a new integration is released, every user on all of our platforms has access to it immediately!

This is the perfect position for someone who is technical, but wants to stay close to the product and customers at a fast-moving startup. You have a knack for staying organized, getting things done, and are interested in managing the technical side of our partnerships with some big name companies. You enjoy not only pushing new code, but also checking in with and helping customers who get stuck using your new features.

You'd be in charge of the technical side all of our integration partnerships, from initial contact, to merging pull requests in our open-source libraries, to meeting with the higher-ups at tons of big companies, to helping enterprise customers integrate new features, to helping automate the integrations pipeline with code.

Not only that, but we've also got a few game-changing secret projects that are going to make getting up and running with analytics tools much faster and we want your help! We're pretty excited about that one.

You'd be joining a team of talented engineers that are in love with open-source[1], and who care deeply about their users and partners, and are focused on always making the right decision for the customer. So if you enjoy working with smart people and helping to build a company that cares about quality, you've found the right place.

Not only that, but if you're interested in writing, everyone on the team is free to write articles for our Analytics Academy[2] which has over 10,000 subscribers. And if you're interested in learning a new language that we don't yet have support for, hack away! We're always happy to launch support for a new library for our API.

A practical way to summarize the difference is that Frequentists refuse to assign the word "probability" to anything other than the output of a formal generative model, whereas Bayesians use the word more broadly and are willing to ask "What is the probability of this hypothesis being true?". The latter is often called "subjective probability" in texts that attempt to discuss the division.

In response to the Bayesians' question, Frequentists say "You've specified no sampling process for hypotheses so I can't answer your question. If you want to represent your subjective belief system over hypotheses as a probability distribution you are welcome to do so by Cox's theorem. But the resulting number should not be understood as probability in the sense of fractional sampling, and we'd really be happier if you'd use a different word for it."

Frequentists and Bayesians agree precisely when the Bayesian's prior is the output distribution of a generative process for the inputs to the problem under study (in this case, biases for coins). If the Bayesian's prior is "just chosen based on judgement" then the Frequentist theory says "That's no longer probability, but it may still be a useful framework for quantifying subjective beliefs and the support for such beliefs from observational data."

So, in your coin example:

Bayesian: anything you want, based on your prior for coin biases. If your prior is symmetric, then 50% as you say.

Frequentist: the question is meaningless without a formally specified generating process for biased coins, but if you tell me the generating process then I can give you a ranking (likelihood) function over all possible biases.
The beautiful thing about this in the long-term is that if Google Fiber succeeds and becomes more widespread, people will start to say, "Why don't we have this?" If this succeeds — and I have little doubt it will — local governments across the country will be under increasing pressure from their constituents to move away from the monopolistic deals most cities have now with Comcast.

I see this as a huge step in the right direction and cannot wait to see how it turns out.

Show HN: Lump.co – instant photo galleries via web search
This is my little side project Lump.co. It's like Pinterest, but you build the gallery by searching the web for photos, rather than having to download photos, collect them, and then reupload to Pinterest.

It's quick as heck, works pretty well on iOS, and is a blast to use.

Motivation/Scratching an itch:

I'm always sending Google Image Search results to people, but I got really frustrated by the long URLs and inability to edit/reorder the results.

I love working on Lump because I use it ten times a day, just for myself. Things like:

1. Picking things to buy visually: http://lump.co/amazon-standing-ashtray
2. Finding recipes by my "desired result" (what I want my food to look like.. sounds silly but it works!) http://lump.co/pork-shoulder-recipes
3. Understanding concepts by quick visuals (I find this to be a really effective way to learn when you don't have time to read a lot of material) http://lump.co/understanding-ios-delegates

It's still pretty buggy at this point, and I think it really needs to be a native iOS app for the best UI/UX, but for now I am ready to submit it for HN's denunciation. :) I'd be eager to hear what everyone thinks!
I respect that point of view.

I have a simple mind and not a very strong vocabulary. I have no doubt that I am probably out-of-sync with popular opinion on this topic.

Why do you say no? The more antennas you have, the cleaner you can keep the beam and minimize constructive interference happening in the wrong places.
What I don't fully understand and what is missing from media coverage so far is how the Ukrainians went from protesting against Putin's manipulation to burning down the place.

There must have been grievances that happened long before this incident, and there must have been a lot of brutality against the protesters to radicalize them this promptly.
Cardless Payment with Loop Fob
That's a very software bubble view of things.

Since 2002, the internet speed at my parents' house in Virginia has increased from about 256 kbps (SDSL) to 50 mbps (fiber). That increase of 100x isn't quite in keeping with Moore's law, but it's pretty damn impressive and talented people at those "intensely-hated digital utilities" are the ones behind it, backed up by the tens of billions of dollars those companies are throwing at the problem.

Practically speaking, you typically run pgbouncer on the same box as postgres.

Even if you ran pgbouncer on a different box, the situation is still better. Suppose you have a probability P of having a partition between any two boxes. Then the probability of a partition taking down the system with pgbouncer is P.

If you instead had N clients coordinating among themselves how many connections to use, your odds go way up. The probability of a partition existing between two clients is 1-(1-P)^(N(N-1)/2) ~= N(N-1)P/2 (for very small P). Once two clients can't communicate, neither one can connect to the DB (because they don't know if the other two have pushed the db over the limit). All clients will need to stop connecting to the DB if any client is ever disconnected from the other N-1 of them.

In a distributed system, ensuring that SUM(x[i]) remains bounded for all time is a tricky problem to solve.
