One thing I'm worried about is Linux. The article says you can add only one partition. If you want to install more than one OS, or have separate root, home and boot partitions, what would you do?
A production runtime for high performance does not mean much: it depends on the cost you're willing to bear. If you have a team of very gifted C/C++/Fortran programmers and have a long-term plan, then great, go for it. But what I have seen more often than not is mediocre developers having unmanageable c++ codebases with so many issues it is not even funny: boost with swig with some multithreading in the mix that is full of race conditions, things that can only be compiled with a lot of voodoo.

Also, the intersection really good C++ programmers + domain specific knowledge is very small in general. I don't think that's where the world is going in general, honestly, except for some niches or areas where skilled human factor is cheap (e.g. academia).
Reading this post makes me think about something I've seen about the (nascent) ecosystem of startups in Mexico (and Latam): There is good participation of women.

And before you take out the numbers and statistics and prove me wrong, I am not talking from a statistical point of view. It is more of a gut feeling (possibly a hope). All I know is that:
- In all of the startup weekends that I have gone in Mexico, there is usually an important participation of women, where they usually feel comfortable and stand out.
- Some of the most distinctive characters in the community are women, like Celeste North, Rocio Paniagua and Ophelia Pastrana in Mexico. Bedy Yang in Brazil and Vanessa K in Argentina.

And this participation doesn't happen in a segregated manner like in other countries (women-only initiatives, women-only events, etc).

Thanks Madhadron, this makes a lot of sense. The Gaussian Numbers define a grid in the Complex plane. This calculation highlights complex numbers which represent best the ratios among Gaussian Numbers. It shouldn't be surprising to find such an ordered distribution.
Looking forward to getting this thing. My first kickstart pledge, kinda excited about that too.
Apple is certainly greedy; you can't have $100B in CASH without being greedy. But, I don't think 21" iMacs not having user-upgradable RAM is entirely Apple being greedy. You know, 21" and 27" aren't like low-end 13" MBP and high-end MBP. They're different beasts, with different sizes, with different guts. Maybe the smaller one needed the RAM slots on one side buried before, say GPU, while the other needed them on the other side in front of HDD and thus was more accessible.

I'm 100% against making desktop computers thin though. Just make it 5x thicker and then cram anything you can inside that thing, and let there be plenty of space for the air to freely blow past GPU so it doesn't burn display. And while you're at it, you can even add some batteries so the iMac wouldn't turn off for a few hours if it's unplugged, or when the power is temporarily out (which results in lost user data, and if they were upgrading OS X, results in "very, very bad things").
Have been thinking about this and wondered about suicide. Assuming you count 100% of suicides as relating to mental health related deaths (which I personally don't), it wouldnt take too many young people taking their lives to lower the population average lifespan. However alone suicide wouldn't take that many years off the average.
that's really cool - reminds me of I think of a similar program google has. Having it at a specific time seems like it could be good. thanks for sharing
This is a great development. Good accelerators create better networks for start-ups and are a much more useful time commitment for start-up founders. Too much of an MBA program relies on past information unavailable to start-ups. Accelerators provide useful skills in a compressed program that is much friendlier to starting a business than an MBA.
It's a command-line-only utility, but I swear by youtube-dl, so you have to be comfortable with Terminal. It requires Python, but I think that's included with OS X, yes?
> Any language that wants to fully replace C/C++ has to embrace "pay only for what you use".

"Pay only for what you use" sounds like a really great principle. But ...

Every user of C++ pays the cost (in convenience and reduced bugs) of not having automatic memory management, even if they don't need its benefits in memory consumption and avoiding GC pauses.

Many users of C++ pay a performance cost for the language's lack of automatic memory management, because getting the best performance from an automatic memory management system requires tight language integration and you can't have that with C++. (So they fall back on refcounting or Boehm-Weiser-like conservative GC, and pay the cost.)

Every user of C++ pays the cost (in ugly syntax and long compile times because of the included-header model) of backward compatibility with C, even if they don't really need that.

Many users of C++ pay a performance cost for this, because the C++ compilation model means that template-heavy code tends to end up with a lot of more or less duplicate object code, which means more cache misses and more time spent paging code in from disc.

Every user of C++ pays the cost (in overflow bugs and the like) of using integral types tied closely to the underlying processor architecture, even if they don't need the performance advantages it brings.

Some C++ users pay a performance cost for this, because if an application actually needs bignums then it'll typically be implemented using some general-purpose bignum system like GMP, which will typically perform very well for really large numbers but may be totally unsuited for smaller ones -- and sometimes most of the numbers you're computing with are in fact the small ones.

C++ uses "pay only for what you use" as a slogan, but it applies that slogan only in a very narrow domain. C++ users are paying, all the time, for lots of things they don't use. Quite a lot of C++ users are paying in performance for things they don't use. The slogan is misleading because it directs your attention to the obvious, explicit costs of features like automatic memory management and integer types that overflow gracefully, but there are plenty of costs that aren't so obvious.

(Lest I be misunderstood: For many applications C++ is a great choice. For some it's the only realistic choice. I am not, for instance, arguing that actually everyone should be programming in Common Lisp or something. I just think "you don't pay for what you don't use" is a really misleading slogan.)
Thanks for the reply; I honestly am not sure about this situation in particular, I was mostly trying to explain how the statement about marginal costs can be true in any scenario.

I didn't actually intend to say that the cost here is mainly bandwidth or X for any X. My point is more than it can be true that the marginal cost of anything can be so many orders of magnitude less than the non-marginal cost for certain ranges that it isn't worth considering. Data sets based on facebook profiles almost certainly come from people approving shady apps or someone set up a crawler in a way that is able to get a lot of information before being detected as a crawler. In either of those scenarios, the person who set it up effectively paid a flat upfront cost and ends up with X number of users, and there are no linear costs (no manual verification or paid data entry at any point). They cannot spend half as much time and get X/2 users or even maybe X/100 amount of information.

In practice they could spend more time getting more users to give access to their random app, but the marginal cost function is just insanely nonlinear; its effectively 0 at some places and probably tends towards infinity an order of magnitude higher than that.
I feel a brick and mortar store is essential to trying out any new gadgets and toys, but then the store would just lose customers to online.

So how about a physical store that charges an admission fee?
Excellent reply, Ben.
Good god, man. What are you cooking? As a student I cooked meat, rice & vegetables (mixing around the meat & veggies as needed) for literally months, and it doesn't take more than a few minutes to get everything going.

I mean, sure, if you want some fancy-pants meal you're going to have to put in some effort. But if you don't want to spend time and still want something healthy, it doesn't take long. (Heck, how long does it take to make a sandwich?).

Frankly, anybody suggesting a personal chef must be off their rocker or living on a different planet than me. It's not hard to cook, even if you're lazy.
Sorry, but unless you were born with a trust fund, a million bucks in real money is still enough to change the course of the rest of your life. You aren't going to be buying your own island, but you certainly won't have the worries that most people have, as long as you're smart with it, as in living like you don't have it.

Your examples explain it. “back hurts, anyone know a good chiropractor”, and "my phone cracked anyone know where to get it fixed.”
People trend to trust other people, so why would they trust you? What curation and validation are you doing on the businesses? If you are rating them, what are you basing your ratings on? These are questions that I think about when I hear your business. Also, it sounds complicated, and non-scalable.

What you can do: if the people are already on twitter, go to them. Create a twitter-bot that people can follow, and it automatically follows you back. When someone says "my back hurts", you use natural language processing on their tweets, and recommend a solution to them, gluing together Yelp, Angie's List, or anything else that might be relevant. Offer three months free, if they like it, they pay a monthly subscription. If not, take them off a list. When successful enough with consumers, you MAY be able to turn around and start charging businesses, but then, you have the responsibilities of curation, and I think it's easier to let companies who specialize in that ( like Yelp or Angie's List) do that, and you piggy back off them. Check if you're allowed to use their data, and if they charge for it.
I agree that beneficial factors are synergistic, and that without this kind of positive synergy unusual longevity is unlikely.

The problem is that such factors are different for each individual. It is a conceit of medical research that generally positive factors can be identified easily. People are quite diverse genetically and biochemically, this is behind the argument for getting a genetic test to identify tailor made drug prescriptions. However, biochemical diversity pales in comparison with psychological diversity.

It is utter foolishness to recommend a wide circle of friends to naturally introverted people, for instance, and, in my opinion, borders on a kind of psycho-normative health fascism, let alone the constant recommendations to "believe in a higher power" to live longer.

In fact, it seems to me that a common feature of interviews with very long lived people is a touch of grouchiness and a refusal to go along with the the received wisdom.

Ask HN: Bloomberg Terminal Resources
Hi,

I recently got access to the bloomberg terminal at our school and went through the training videos available in the platform.

There is a lack of resources / forums on the web on how to best use this data to be able to trade better.

Do any of you have experience with Bloomberg and can mention how to use this powerful tool to make more intelligent trades
I would be far more interested in a discussion about how we could identify the factors that lead to a community that doesn't appear to be following the aging and health norms of other communities rather than just saying "the article is stupid and isn't worth reading".
I share your paranoia in general (as ops), but can assure you that regions are very isolated from one and other. I know that releases are rolled out on a very long schedule (think quarter long release), and that is to prevent what you describe.

I would argue that the application (ie: the application being hosted on AWS) probably is going to fail before multiple regions do simultaneously and that should be addressed, before thinking about going multi-provider.

- Up the font size on your blog, I can't read it without zooming in considerably.

- Try to actually explain, giving examples help, what the different security parts do rather than quickly explaining, this blog post feels as if it were written up in 15 minutes to sell your product rather than being informative

- Don't be afraid to use markup other than anchor and paragraph tags, for this article using subheadings for the 3 types of security would make the article easier to follow (remember people love to skim).
Decoupling the concept of "you don't intimately know what I have spent my entire life playing with" from "stupidity" seems to be really difficult for the tech crowd.

Always sad. People willing to discount countless hours of expertise and knowledge because a user doesn't know what the name of their browser is. As if that means anything.

For example, I really don't give a shit if my neurosurgeon is aware of what his browser is named. Nor would I dream of calling him stupid if he didn't. Chances are he knows leaps and bounds more about me on most topics, just not casual desktop computing.

Likewise, discounting someone entirely because they're uncomfortable with or uninterested in computers is one of the most ridiculous, ignorant, and self-absorbed things you can do.

Probably as important as a physical store is developing a customer base of early adopters, tinkerers and modders who will support/modify/bugtest/buy early hardware projects. Whether you reach them via a store/site or events (annual/monthly/quarterly) is less important, than for a hardware startup with a new product to know that YOU are the place to go to launch the product/find beta testers etc.
I'm not seeing how this is unfair. Facebook is a business and the companies which set up fan pages are not typically charities (and so what if they were).

Facebook has a level of PR software as service which is free. They have another which is premium. If a company wants to spam their "fans," they have to pay.

If a business wants to have a high level of control over communications with it's fans, customers, likers, or whatever they are called, there's no free lunch. Either pay a third party (e.g. Facebook) or invest the hard work.
That attack is far from trivial. There were other attacks against EMV in the past, but they're fixed as they come.

Did you read my comment? I explicitly said I am not begrudging them the opportunity to make money however they want. If you want to quibble over the denotation of "conflict of interests" fine, let me put it this way:

It's not sustainable for Facebook to degrade the usefulness of their service in this way for a short-term cash gain. 15-20% throughput to fans is so low as to confound expectations, and I'm saying this will bite them ass.
> So does it apply to all SDA's or just in Loma Linda.

Applies all across the country. Scientists looked at just high school grads w/o college, or those with four year degrees. You could group by people with incomes above, or below, certain thresholds. You could throw out irregular church goers and only look at evangelicals or conservatives by denomination. SDAs consistently emerged as the longer living group, no matter how grouped.

And regardless of the slicing, the factors most indicative proved to be how closely the health plan is followed. Looking within the SDA group, and dividing by adherence to the health guidelines, found the differences there as well.

Unlike your sibling comment suggests, this was not a black swan.

> although entirely non-meat diets commonly hurt from inadequate amounts of iron and in some cases protein

This is a common misconception. It's remarkably easy to get more than enough iron and protein in a non-meat diet. See http://en.wikipedia.org/wiki/Vegetarianism#Protein and the next section for some specific food ideas.

SDAs have espoused vegetarianism since the 1800s, and have been focused on diet and health since the beginning. In fact, there's a good chance you ate food formulated by the Kellogg brothers this morning...

To quote Wikipedia:

Kellogg's was founded as the Battle Creek Toasted Corn Flake Company on February 19, 1906, by Will Keith Kellogg as an outgrowth of his work with his brother John Harvey Kellogg at the Battle Creek Sanitarium following practices based on the Seventh-day Adventist Christian denomination.
When someone recommends a service, the assumption is that they're linking because they really find the service useful. If it's a referral link, the issue becomes clouded - are they recommending it because they genuinely think the service is useful, or do they just want the cash?

I'm not against bloggers using referral links, but I think they should make it clear when they're using them. Their recommendation carries less weight if you know that they're getting paid for everyone who signs up through them.

Also, this line:

If you buy one of those items, you probably would have bought it anyway.

If this was true, no one would ever need to pay for advertising or referral links. But clearly, people do pay for advertising and referral links. Ergo...
Absolutely. This isn't a change from 100% of fans seeing a post to 0% of fans seeing a post, either. Even when Facebook just chronology to organize the Newsfeed, plenty of people would miss a post just because they weren't at the computer at the time. This is just a different, maybe better, maybe worse, way of organizing the Newsfeed.
One of the HN guidelines is "please don't use HN posts to ask YC-funded companies questions that you could ask by emailing them." Similarly, I think you might get a more authoritative answer to your question if you contacted the author directly.

You should be aware that Steel Bank Common Lisp is, in many cases on Ye Old Shootout, close to static binary performance. Certain blog posts from some of the community record results that have beaten C++ results. (Numerical performance, as I recall, but don't quote me).

My point is that in certain scenarios where you need performance but aren't willing to pay the C++ grief, you can get away with better languages without significantly sacrificing.
Why did this get so much traction on hackernews?

This was posted on Reddit and killed with one comment the tl;dr of it : The client was incompetent and irresponsible and likes to blame people when things go wrong.
not sure if this is related, but something my (female, astronomer) partner has commented on in the past is that the more traditionally "macho" societies (s. europe and latam) have (proportionally) more female astronomers (and perhaps other scientists) than the "more equal" western countries. she doesn't know why, but i think may have suggested once that it could be because they traditionally give more "space" to women, while in the usa / uk, women have to compete more directly with men (and since men are in the majority, the game is framed in male terms, and men therefore tend to win).

so a rephrasing of the last point is that it is in fact something similar to the "women-only" segregation, in a sense, but more deeply ingrained in the culture...

of course, the interpretation is pure speculation, but i am pretty sure she's right on the numbers.
