Yeah I charge mine once every few weeks. It takes about 20 minutes. If it played MP3s from an SD card it would be perfect.

Not having the maps is occasionally annoying. Aside from that it's great, there really is no good reason to have a web browser in your pocket that can outweigh the damage from having the internet creep into real life.

But then I never really used any apps back when I had a smartphone anyway. Maybe the highly industrious networker types won't find it so simple.
How much time do you think doctors have to spend with each patient, and would you consider that a tight deadline?

The time pressure on programmers due to business needs limits the amount of time they get to spend with their code, much like the time pressure on doctors due to business needs limits the amount of time they get to spend with each patient, researching the latest anti-vax theories, etc.
Do you consider yourself to be a sociopath?
I wish redis had synchronous write option to guarantee that when a write response is received that all nodes in the cluster have also received a copy. Even if this was just an ack that data is replicated into memory instead of disk. Sure there are cases where you'd rather operate with async, but really I would prefer to put haproxy in front of 3 - 6 redis nodes and let it load balance both reads and writes similar to galera cluster with keepalived and a vip I would not need to be concerned with split brain assuming synchronous writes...
This is such a great idea for a response though. If in the middle of a conversation, and someone whips out their iPhone on you, BOOM...broadsheet
I'm not judging other people. I think it's a crisis of self control for me as much as it is for other people.

I'm still undecided on whether stuff is getting more addictive (http://www.paulgraham.com/addiction.html), or we're losing our ability to control ourselves, or both.
> People would make their own entertainment if sports and Hollywood were not available

I'm afraid I disagree with you. I notice even when getting together with a group of friends to play games, there always tends to be someone who is happy to just sit back and watch the games take place. Some will make the entertainment and others will want to watch. It seems to be basic human nature; professional sports and Hollywood have just figured out how to make money from that.

Is this true? The brightness decays quadratically with the distance, so I guess that the reflections decay also quadratically not exponentially.
I am at the same stage at the same sector, though I am in Brazil. My startup is a loyalty program for bars and restaurantes based on Facebook's checkin.

What I am doing for the last month is a kind of "door-to-door sales". At least my product may benefit if my clients are geographically concentrated. So I selected two neighborhoods with a lot of restaurants, then went door to door asking for the owner just after lunch.

Local biz owners are usually at the business, so it is not hard to be introduced to them by whatever employee you aproach first.

This won't give you scale, but I would strongly recommend you to follow PG's advice: http://paulgraham.com/ds.html

Doing this not scalable door-to-door aproach you will learn a lot (I did), it is a great form of customer discovery. And if you are able to acquire a few customers on the same neighborhood, quoting the same PG's essay:

"Sometimes the right unscalable trick is to focus on a deliberately narrow market. It's like keeping a fire contained at first to get it really hot before adding more logs."

I actually could get in my hand a XLS with thousands of restaurant's emails, but decided not to use until I get closer to product/market fit through this door-to-door tactic.
> So why doesn't everybody get the safer one? Manufacturer cost.

What is your evidence that there are unsafe vaccines currently on the market that are being promulgated over safer vaccines due to manufacturer cost?
I used to estimate small websites (<70k lines of PHP), and generally got to around 30% of the final time required. My method was to fully describe the product, then break it down into tables, queries and pages. Estimates were based on the previous project's stats and final times required. (My constant used to be 3, but technology changes altered the numbers.)

The big unknown - and the highest risk - was managing integration between external systems, or doing complex integration between internal systems. Anything that might benefit from aspect-oriented programming, like access control lists, or a more elaborate front-controller, or universal exports in json format, or a new paradigm like AJAX, would be difficult to estimate.

That fits your breakdown of projects into linear parts, and exponential parts.

Anyway, my estimates were good, but my business management was not - I was always in learning mode because I never studied business and had no experience. So I went W-2 and went into a different field because an opportunity to learn politics emerged. What's interesting is that successful political campaigns are entirely about estimating and budgeting, in real time more or less - you spend money and see results day by day, or after a couple weeks. It's driven by statistics (and messaging). I just watch from the sidelines, and don't do politics, but I think we could learn something from it. It's more like agile XP than waterfall.

The Obama campaign was XP, by necessity. The Healthcare.gov website thought it was waterfall... again by necessity.
GNU Hello exists for this purpose.

It's nice to see such long term data put to use and to be shown in graphical form what everyone has been screaming vaccines save lives!

Yes I get vaccinated yearly for the flu, I also got one for H1N1 (?) a few years ago.

So many people across all age ranges it's sad, the comments in the NYT article are sad to see. A 20 something guy at work was telling me excitedly how "some guy" on YouTube "proved" writing the word hate and love on water bottles then freezing them makes the ice different. This same person is against vehemently against all GM foods and Big Pharma, the "some guy on YouTube" is the all-knowing answer.
This is a terrible comment, and I want to explain why. It subtly changes the subject.

It's not about what others think of your technology use. It's what you think about it yourself. The reason many of us feel moved by the article and the video isn't some need to tell others what to do, it's the recognition that we ourselves are missing out on important parts of life in some kind of weird attempt to become a TV reporter.

So sure, for the .1% time that you're texting your sick wife with cancer and she's able to vicariously experience things, you are probably feeling pretty good about what you're doing. Now how about the other 99.9% of the time? Do you personally feel that all that tech use is in the interests of some greater good? If so, have fun with it. After watching my own habits, I am very doubtful that this is true. I see people all the time use tech in such a way that's directly opposed to their own best interests -- and they're smart enough to realize this, too. The problem isn't my judging them -- heck I don't care what people do -- it's that we're turning into a society that's spending significant time doing things that we don't want to do. They just give a bit of immediate gratification.
Can you explain why you think the vaccinations for infants "seems rushed"? What's the basis for that?

As for the ingredients, that goes for most medicine. Medicine is often stuff you wouldn't want to be eating or touching routinely, but that's because it's for non-routine use. I wouldn't give my kid a big bottle of acetaminophen to chow down on, but I will give some of it to her when it's medically indicated.

As for signing a document of liability, would you sign one if you thought that the procedure was generally safe, but there was a one-in-a-million chance that, through no fault of your own, the procedure could go wrong and leave you bankrupt because of what you signed?
Pretty soon you won't be able to buy anything but a smartphone.
This is a neat idea. Does anyone know if it's possible to achieve a similar effect natively on Linux ? i.e. make the linux network stack load-balance all outgoing connections to all available interfaces ?

Indeed, the problem here is the type instability in the inner loop. There are a few optimization techniques that we intend to implement to deal with that but as you noticed, we're not quite there yet.
> I'm wondering if a doctor would balk at signing a document of liability for {x} resulting from vaccination. If she wouldn't put her career behind her belief, should I believe her?

Suppose a doctor vaccinates 20 kids a week, for 50 weeks of the year (1000 kids per year). Suppose each vaccination has an average of 3 different vaccines (i.e. against 3 different diseases). Suppose the average vaccine has a 1/10k chance of serious complication. So over the course of a year the doctor gives about 3000 vaccines each year with a 1/10k chance of serious complication. Suppose a single serious complication risks their career. This means the average doctor is risking their career over 1 incident just over every 3 years. I personally prefer a family physician with more than 3.3 years of experience.

Meanwhile over those 3 years 9000 cases of disease were eliminated. Sure your kid may mean everything to you (mine sure does) but having a doctor put their career on the line for something that only has a probability of success is silly considering how many times they roll the dice in their career.
That's in the plan, it's just not implemented yet. (It's implied under the Note: Redis Cluster in the future will allow users to perform synchronous writes when absolutely needed.)

What shocks me, as a bicycle commuter, is the number of people who cradle their smartphones in front of them while they drive.

It's selfish and dangerous as hell, and those who do it exhibit the same really obvious symptoms as those on foot.

Lack of situational awareness, delayed response, and the poor decision-making that results from those.
Partly for historical reasons and partly because Prelude is really intended for beginners.
Flu vaccines are 60% effective, so you're 60% less like to get sick after getting vaccinated. In layman terms, someone who normally gets sick 6 yeas out of 10 would now get sick only 2 years in the same period.

The problem is not your ignorance (we're all ignoran of many things), it's the combination of ignorance, willingness to hold a strong opinion on the subject, and simultaneous lack of curiosity to explore the subject.
They've published their data, which is fantastic and by far the most important part of the article. http://www.tycho.pitt.edu/

I have to take issue with some parts of the article. Lohr (the NYT article's Author) cites 38,000 cases of Pertussis in the US. It may just be a coincidence, but 38,000 is the number of cases recently reported in Australia. The CDC reports[1] 27,550 for 2010 (an awesomely precise estimate), so, 38k doesn't sound out of line, but I didn't find a source for that number. Going back to Australia where they have 95% compliance according to this news article[2], they suspect that mutation of the pathogen is responsible for the rise in cases. The NYT article OTOH, lays the blame on non-compliant parents. Additionally, the acellular Pertussis vaccine apparently doesn't always prevent illness, but lessens the severity and duration of infection. So, it could well be that most of the reported cases were vaccinated as was the case in Australia.

I wonder why authors feel the need to keep re-writing the standard pro-vaccination puff pieces. They don't seem to do anything to convince skeptics. I'd like to see a study of why people choose to refuse vaccines and apply those results to efforts to increase vaccination rates.

Getting invited to some developed country by some lonely soul. Get that person to come to their country and then drain their money. There are really guillable and desperate people out there that just stop thinking as soon as somebody fakes interest in them.

But how would Match profit? They have millions of users. What changes if they have millions and a few thousand?

It's been almost three years since I began spending nearly every available evening and weekend learning code and web dev. It's been a great adventure. However, contrary to the advice I was given I believe Ruby on Rails is not an effective place to start learning web dev, it certainly wasn't for me.

When I started, I had limited knowledge of HTML and almost no experience with CSS, Javascript, SQL or HTTP. I felt bombarded going through Michael Hartl's book (ruby.railstutorial.org), for example, trying to pick up all the concepts mentioned above plus the ideas of Unit Testing, ActiveRecord, the MVC paradigm, Rake, GIT, Migrations, layouts, partials and UNIX, to name a few. Nothing was sticking.

After now learning some programming fundamentals through an awesome Coursera course, learning C++ and Python to make small game mechanic, digging into PHP and launching a few fun websites, building a few projects with raw HTML and CSS while having lots of fun with jQuery and Javascript I feel I am ready for and can appreciate Rails. I'm now approximately 4-6 months from launching my first commercial product and this book will be perfect for my current purposes. I'm 25 pages in and can say that I love it's narrow focus (not including unit tests, for example) and also it's thorough explanation of all core concepts. I've backed the Kickstarter and can't to keep learning! Sorry for the long post HN! Long time lurker, big fan.
Yes. It claims to be updated in 1999.
The flu vaccine certainly is effective. It is not 100% effective, but it is still effective. Getting it makes you much less likely to catch the flu than not getting it. For vulnerable people, this greatly improves their chance of survival. For the rest of us, this greatly improves our chances of not spending a week in bed. Plus, if a significant proportion of the population gets the vaccine, that reduces the chance of it getting transmitted, making it even more effective.

Speaking of cost, my HMO gives my family flu vaccines for free. The only reason they would do this is if they think it's cheaper for them overall, because the campaign reduces doctor visits. They may be motivated solely by profit, but in this case, their desire for profit lines up with my desire for health.

I can't believe you seriously ask why kids are getting so many more vaccinations than before. You might as well ask why kids are getting so many more surgeries than before. Kids get more vaccines today because more vaccines are available. Obviously, kids weren't getting flu vaccines before the flu vaccine was actually developed.
Along this line I would find named Lua scripts useful, so multiple clients could access script functionality without uploading themselves, or having to retrieve the SHA1 from a dictionary.

This idea may of course be contrary to the expected use of Lua scripts in Redis, and an attempt for the RDBMS part of my brain to look at Lua scripts as stored procedures.
I think we can safely diagnose an epistemological crisis in our society - indeed many if not most people cannot tell the difference some guy on YouTube and a body of statistically validated controlled studies.

Not sure what the treatment should be.
heh here is where i need to apologize for not paying attention to .NET :(

i had a bad experience with it in my early days of webdev. moreso my fault than microsoft, but by the time it was over i was firmly lodged in the open source world.

Netflix has many other cool Java libs besides just RxJava, but by all means give credit where credit is due. Interesting to know
A naive implementation in Nimrod:

proc main(max_a0: int): int =
var a, longest, len, max_len : int

for a0 in countup(1, max_a0):
a = a0
len = 0

while a != 1:
len += 1
if (a mod 2 != 0): a = (3*a + 1)
a = a div 2

if len > max_len:
max_len = len
longest = a0

return longest

# Main program starts here
echo(main(1000000))

Takes 0.76s (the C program in TFA takes 0.58s)

http://tallguywrites.livejournal.com/148012.html

> but it did make a lot of people ask questions.

Easily answered questions

> Why are kids today getting so many more vaccinations than before?

Because we now have vaccinations that are safe and effective. The alternative is dead, or crippled, people.

> Why are more kids getting diagnosed with autism?

Because we have more doctors able to diagnose; we have diagnostic criteria; we have parental awareness.

> Is there a causal link?

No.

> Why instead of single shots are different shots getting combined into one super cocktail - to save money, cut corners?

Vaccines that are cheaper and more effective are a good thing. Someone would have to be some kind of fucking half-wit to think otherwise.

EDIT:

> If you read Ben Goldacre's books

... and came away thinking there's any serious risk from vaccinations then you need to re-read the books.
Of course, you have to try really hard to even find newspapers anymore, and people didn't "go out to dinner" carrying the paper, but yes, I do remember plenty a time when many people would lose themselves in the newspaper while at the table, for breakfast or lunch, both informal and not so informal settings. I guess I do "endorse the message behind that photo".
This is a terrible comment and I want to explain why. It uses hyperbolic language in an aggressive manner far out of proportion to content of the comment it is replying to.

Youtube comments are generally terrible. Stormfront comments are terrible. 4Chan comments can be terrible. This comment had content directly related to article it was replying to, talking about the utility this technology can provide, and also that the main thrust of the article and the video it contains seems to be someone else's value judgement on what other people should enjoy.

So sure, for the .1% of the time that a comment on this site is actually derailing or contains just blatant flamebait, trolling, attacks, etc it probably feels pretty good to call it out as terrible. But for the other 99.9% of the time? Have some perspective, grapple with the content of the comment, and do so in a non-aggressive manner entirely in proportion to what you are replying to. Don't go for the over the top hyperbole, no matter how much immediate gratification it gives you.
"good"? I always found that it was extremely annoying and a hell to get done right, what the fuck with all the different options? Until today the last tool i wrote that i wanted to have unicode-proof still spits out the occasional warning, but i just don't care anymore for the warnings that pop up. Even if perl5 can do unicode, it's a nightmare to use, imo.

And the first comment (which i did go through for my ventures into perl unicode) is nothing but prove how broken it is. So maybe you are just being sarcastic and i didn't get it.. ;)
This attitude is maddening. You're not perfect, so you have no place pointing out other people's flaws? Ridiculous!

This is also the third time I've seen it expressed in the last half hour. Where do people get the idea that no one should be allowed to criticize them unless the critic is a flawless person? Is this the result of the "you're a special person" upbringing many of us suffered through?

Are you a perfect programmer? No? Then shut up, my code works. Are you a perfect father? No? Then shut up, my kid's behavior is none of your business. Are you a perfect driver? No? Then shut up, dotted lines are just suggestions.

No one is perfect. If you can't deal with criticism, consider it a reflection on YOUR character, not anyone else's.
Another great example of someone on HN trying to be the smartest most critical person in the room. You totally missed the point of the article.
Data is only going to get cheaper, and voice and SMS only plans are only going to get more scarce. Even without a data plan, prepaid in fact, 3 are 'only' charging $0.016 / MiB here in the UK. I remember when web hosts were charging rates that high.

In another few years it's likely you won't even need to make the decision about whether you need or want a data plan or not. You'll just get data. At least I hope so.
Cool project! This is a really promising area of research.

Our group at Stanford recently published some early work that shows how a different kind of large-scale collaboration, via MOOCs, can be combined with theorem provers towards pedagogical ends. http://hci.stanford.edu/publications/paper.php?id=260
Hi there, I worked at Match for a while and the basic scam pattern I saw was this: a scammer will create an account and send a ton of messages to recently active users, the users that respond will be immediately prompted to take the conversation to email (away from Match's PM system), and once they're off of Match they ask for more personal information.

I never went further down the path than that but I'm sure the scam could evolve along the lines of "I am your one true love please wire me money to buy a plane ticket to come see you."
Anyone can put forward a bill, that will then die in committee or never make it on the agenda for a vote, or fail to come to pass in a thousand other ways. I don't care enough to know the exact situation here, but it's very common that ranking law makers are able to exert control using procedural rules to determine which things can even be voted on, and which are not.
