One of the cornerstones of selective breeding is systematic inbreeding. This brings out recessive traits and encourages the accumulation of what we would normally consider mutations and errors. By selecting individuals that have desired traits, this engine of change is harnessed to produce the desired end results.

Consider how we would view humans who had been selectively bred long enough to change their form as drastically as some dog breeds have been changed! We would be horrified by them. However, the deformities accumulated by this population, when reunited with a larger population, would soon disappear. No doubt we would would view this as repairing the damage done to their genomes.

As for breeding dogs with the ability to sniff cancer... First, you have to get your hands on the raw materials. i.e. Find dogs who already can smell the stuff. Then you have to hope at least some of their offspring will have that trait. Next, you need to figure out how to reliably train dogs with the ability to smell cancer to actually do so and communicate the results, and you're probably going to have to do this with dogs you don't necessarily know actually have the ability. Also, you will need to be around people with cancer on a routine basis so you can test/teach your dogs. I'd be willing to bet few oncologists will say things to their patients like, "Gee, you're absolutely riddled with cancer! How would you like to help out with our cancer-sniffing-dog breeding program before you snuff it?". Finally, you have decades or even centuries of work ahead of you before you'll have a breed on your hands with greater ability than random gifted individuals in the greater dog population.

The fact that some dogs can smell at least some forms of cancer suggests that there is a mechanism for detecting cancer to be discovered. It would be much faster and far more useful to determine how dogs detect cancer and develop instruments directly based on that method. The state of modern science is such that breeding animals just takes too long.

I think there can be a certain inquisitiveness that those under 30 have which dwindles as one ages. I wouldn't say 30 is the point where that all breaks, but certainly he has a point. That inquisitiveness, I think, leads youngsters to try new things and come at problems from a new angle.
JavaScriptCore also has bump-pointer allocation, as mentioned by the post. We don't use it for all things but we think our tradeoff choices are pretty good.
The most common incarnation of Bartlett is a semispace mostly-copying collector with bump pointer allocation. You never leak a whole space. The only requirement is that the spaces are a discontiguous bag of pages. Note that in proper GC terminology this is the right way to say it - a space is not a contiguous region but rather an abstract bag of heap locations, though usually it's a bag of very large pages, like 64KB in WebKit. You'd want discontiguous spaces anyway if you want to support dynamic heap growing/shrinking or other features like pinning (for fast FFI), etc. It's usually only either academic collectors, or collectors in one-VM-per-process systems like server VMs, that can even afford to make a space be a contiguous region of virtual memory. So, Bartlett ends up incurring zero net overhead for embeddable VM environments like a browser engine.
If you install web analytics on your website you can track how many of your visits have come from Facebook (or any other site) easily! No further code required.

If you trust Google and want a simple, well supported solution I recommend the free http://google?com/analytics

If you don't trust Google or another business with your data, there is an open-source analytics tool named Piwik that you can install on your own server and use to track your sites.

Both of these solutions should provide traffic source for you and can also be configured to automatically send you reports on a regular schedule.

Hope this helps!

Of course.

But education systems are a product of political and, consequently, economic belief. We believe in a nominally equal distribution of power, but we also believe that most people are destined to be industrial cogs, with disproportionate power going to an elect few. That's what our school systems reflect: niceties declaring equality while applying a rigorous filter in order to determine the worthy.
If your private financial information was published online, you should have the legal right to have it removed.

Private financial information does not belong online.

Do you believe, for example, your bank should have the legal right to publish the historical accounts of all of its customers tomorrow? Should that be protected by the right to free speech?

Almost nobody would think that was acceptable, because private information is private. Data Protection of private data is a legal idea that we generally accept in Europe, even if we don't do a good job of enforcing it (as perhaps we haven't here).

You should also have a right to legal access that would allow you to ensure your legal rights were upheld without worrying about the cost, but that is a separate issue which is really nothing to do with this guy.
I doubt that first version of Facebook should be considered some pinnacle of engineering.
Every one of these threads about age seems to turn into a circlejerk about how awesome being old is. It makes me wonder, is it just the old people feel the need to defend themselves in these threads, or is HN actually getting older? Maybe its picked up a lot of ex-slashdot users?
It sounds like they're intentionally doing this, to create a problem for people migrating away from their service.

Actually there are 2 links, the one named "Create token" goes directly to the token generation page. The "Help" link goes to Readme just in case people wonder why they have to enter the token. I guess you clicked on the "Help" link instead of "Create Token" link?
Thanks for the advice! One question I still have- I'm sure that the tips you've shared will work in the long-term and pay off far more than making a quick buck, but any ideas how I could find good projects/jobs from people outside of my personal network?
Does ageism have as much of a perceived presence in tech culture in regions other than the valley?
I'd be interested to know the number or ratio of startup created by under 30 and have failed vs number of startups created by over 30 and failed. My guess is there'd be less failure by over 30 founders.
Sure, but was that because Wozniak was < 30 or because he just was a beast when it came to these things?

Is this a joke? As a designer I looked at two things: their landing page banner and their revamped bill design. Both are terrible.

The banner is large bloated text crushed together, muddled by poor color contrast, offering no reward for making the effort to decipher it.

The bill is worse. The "bad" example is exaggerated by fluff (adjustment lines & benefactors) but at least makes a case for what's due when and why. The "good" bill comes off like a phishing scam: you owe us so pay us, in headline print size, without explanation or context. Bad juju.
I use coffeescript too, so I should be able to use reactionary to write the dom helpers it exposes in my JSX. So then the coffeescript -> jsx on server side, then jsx -> javascript browser side, is how it works, right?

I think I'm slowly being convinced putting it together in the same file makes sense, since it's a single component, and the what's being displayed is coupled with what you'd do with it, so I guess it should belong in the same place?

To change tack a bit, because I don't have data to answer your question: Am I meant to think that 70k is a really high median salary for the teaching profession? Because I really don't - it seems really low for such an important profession. Especially now that so much teaching at the college level is done by similarly low-paid adjuncts, I wonder, why does it seem like our society doesn't think teaching should be an attractive employment choice for the smart, talented, and well-educated among us?

As a consumer, I'd be very unlikely to buy a car that would kill me to save strangers. Not that I don't care about strangers, but to me my life is simply more valuable. So given a choice, I'd pick the model that did everything to protect me, my friends and family. I assume most people would do the same..

I'm understanding and doing stuff now in my mid-thirties that my young self only wished he could do. To boot, I'm more excited and passionate about my craft than ever; certainly more excited than I was in my mid-twenties. I don't see this trend changing anytime soon.

Then again, I'm probably an old engineer at heart :) I love talking to those guys in their 50s that were programming COBOL or assembler before I was born. I was sitting in a career course thing recently and some of the older guys were sharing their experiences applying for jobs; all I could think was that I'd love to hire these guys if I had the means. Give me a wise engineer any day.

Zuck invented FB as a 20-something. Bradeen, Brattain, and Shockley were 37-45 when they invented the transistor. See: http://m.theatlantic.com/health/archive/2014/02/big-breakthr... (breakthroughs happen in late 30's).
the article focuses on the cardiovascular benefits... which appear to have been self-propagated by some adhoc "because x study says it helps!" without anyone doing critical thinking on their own part.

Unfortunately it isn't apparent that that is the the focus until you look at where the article is hosted. So I'll vehemently agree with your initial observation that the original title is link-bait at best.

There are many studied and documented benefits of fish oil. This hardly "puts a nail in the coffin" for the supplement but hopefully it gets people thinking and some more studies funded so we can get a better picture.

Of course if our food just had a better omega-3 :omega-6 ratio we'd be in a situation where the supplement wouldn't be the necessary...

That's because the features require location data. If you don't want the downsides of location data, you can't get the advantages either.
The Oatmeal Asks Elon Musk To Donate $8 Million For the Tesla Museum
JOSE includes JSON canonicalization, which scares the crap out of me. If I had the choice, I'd treat JSON as binary --- a whitespace change would, for a signed file, break the signature.

JOSE also includes RSA PKCS1v1.5 signatures, which are deprecated (you should use RSA-PSS, which JOSE also documents).

It includes naive nondeterministic DSA, which should be deprecated in favor of deterministic DSA or something like Ed25519.

It doesn't include details you actually want about curve selection. (Also, P-521?!)

It includes encryption under RSA PKCS1v1.5 (encryption with v1.5 is even worse than signing under it) and AES-CBC, which is disfavored by cryptographers.

(My understanding of JOSE is cursory, at best, so I wouldn't be surprised to be corrected on any of these).
Presumably you still leak individual pages if you have stuck stack pointers though?

I guess around turns of the event loop you can probably get precise compaction though, since nothing's on the stack.

Edit: I didn't think that it was correct that all production-quality semispaces are scattered throughout the address space and indeed it's not (though I probably misunderstood you): SpiderMonkey uses a contiguous-in-memory nursery.
Mistake in the "With pattern matching you can save a few lines:" section, the clause matching nil should probably go first, otherwise the user variable ends up being bound to nil.

Do you think this attitude explains some of the epistemological issues behind the anti-vaccine movement? I'm pro-vaccination, but I find it weird when people mock others for not believing vaccines are safe and then go on to criticize GMOs and the validity of nutritional studies. (Not saying you're doing this at all, this is just a tangent.)

Of course, vaccine studies are probably way more rigorous and easier to control than figuring out the complexities of nutrition, but it is a little unsettling how easily doubt can metastasize. There's really no solution here other than trying to spread scientific literacy and helping people understand the rigorous testing of modern medicine, while also encouraging them to think twice about the sensationalized studies they read.
The original EMACS was written by Richard Stallman and Guy L. Steele, Jr. when they were 23 and 22 respectively. Fortran was proposed by John Backus when he was 29. The first lisp implementation was created by Steve Russell before he was 30.

Those are just three of four things that I checked (John McCarthy was in his early 30s). The idea that once you're over 30 you can no longer hack it is absurd, but that doesn't mean that the opposite has any truth to it.

Edit: Ada Lovelace wrote the first computer programs when she was 27-28.
I'm struck by the vignette involving the table leg, in which Oliver describes it as feeling "unnatural" to pass his kinect-sensed leg through the virtual table leg, even though there was no obstruction in "real life." I believe this is a demonstration of fully-convincing immersion, and Oliver is sure to point out its implications for the uncanny valley. This is so exciting from the perspective of social/cognitive science, too. I'm floored.
Tech innovation is accelerating.

The old guys vastly underestimate the productivity difference between old tech and hip new tech.

The young guys vastly overestimate how much of their productivity is due to their own smarts rather than using hip tech, and don't sufficiently appreciate that when they get older, the experience they've accumulated won't be worth much, either. Re-learning everything every 5 years is only fun the first and second times.

But certainly, years of experience with some tech is becoming less and less valuable, as the tech is changing faster and faster.
Part of the distaste is that many of these SaaS stocks are trading with valuations as if they're already at the far end of the J-curve. The market, evidently, agrees with Marc, so I'm not quite sure what he's complaining about.

I look back at things I said and thought a couple years ago and am amazed at how little I knew then. Then whenever I think I really understand something I remember that this has been a pattern for more than a decade.

Now I just admit that I am probably clueless and just try to make the best decision with what I know now. It's helped me to be a lot less cocky.
Irrespective of your reply to the person above, I think the default position for making claims should always be supporting them and your premise.
I've actually improved with age. Oh sure, I don't crank out reams of code as fast as I once did. But I manage now to produce rather more functionality with less code.

The Oatmeal probably should have tried to first contact Tesla Motors or Elon Musk privately. There was no need to resort to a public plea.

Its a lose lose for Mr. Musk now. If he pays up then he'll be open to future requests. If he doesn't he'll be the billionaire dick who won't pay up for a good cause.

Again I’m being lazy about looking it up but if not specifically in writing at least in spirit I believe one of the purposes of the armature radio program has been to advance wireless communication and technology.

Right now strong encryption and authentication are where most of the efforts in the field seem to be focused. It should be at the forefront of the experimentation being done by amateur radio operators.
