> Let's find the most obscure explanation for X UFO sighting that may or may not be true (aka. large spider webs that fly up to 14,000 feet in the air) while ignoring the other 100,000 + sightings per year around the world.

The media "ignores" the millions of religious miracles people "witness" each year for the same reasons.
Of course. That's the point!
>Yeah, he hired me when I was at Google and have kept in touch.

So?
So pretty much everyone in the US who owned a computer was on in the inside.
The number of people who add up arrays of floating point numbers and don't know about Kahan summation is really incredible.

>Why is it so hard to imagine and believe that other intelligent civilizations on other planets exist and that they might be thousands if not millions of years ahead of us?

It isn't.

Why is it so hard to understand that the likely existence of life in the universe and the credibility of the UFO/abduction phenomenon are completely unrelated? Given the vastness of the universe, there could be empires spanning millions of worlds across a distant galaxy, and they could still be completely unaware of our existence, and we of theirs.
And here i was hoping for a program that can play if http://en.wikipedia.org/wiki/Breakout_(video_game) or a clone of it is being played. :(
So something like lightly armored rocket artillery with a screen of antipersonnel/reconnaissance drones that could paint targets for guided rockets. This might work well until you need to take enemy air force into account.
No doubt immersion is the way to go.

But it still seems to me that countries where students learn foreign languages successfully at a high rate start those students before they're 12. My two years of high school was a waste, as you said yours was. But Germans (and Dutch, and Norwegians, etc.) have much better success in their schools, and they all start before the age 14 that's common for starting here in the US (though that's starting to change).
7 Minute Scientific Workout Timer
For those interested in this topic I would recommend checking out the researcher Nick Bostrom and his book "Superintelligence".

Here's a review snippet: "Nick Bostrom makes a persuasive case that the future impact of AI is perhaps the most important issue the human race has ever faced. Instead of passively drifting, we need to steer a course. Superintelligence charts the submerged rocks of the future with unprecedented detail. It marks the beginning of a new era."—Stuart Russell, Professor of Computer Science, University of California, Berkley
My day job used to involve parsing some fairly ill-formed languages, so I developed this: https://github.com/Logicalshift/TameParse

I noticed with the languages I was working on, the problems could be resolved by being smarter with the lookahead: this parser allows for context-free lookahead matching to resolve (or detect and defer) ambiguities.

That makes it possible to do neat things like parse C snippets without full type information or deal with keywords that aren't always keywords (eg, await in C#).
Well no.

It went more like this:

Does HN really believe in UFOs? Let's assume for the time being no.

Is the sudden influx of UFO articles then based on HN popularity or is there a campaign to introduce this content (these campaigns are common, although I do not know how popular on HN)? Let's assume for now that the articles are part of a campaign.

What group with what motivation would benefit from said articles. My first thought here was in fact TLAs/spooks. But only on entertaining the hypotheticals.

A 'viral campaign' for a UFO movie is also pretty reasonable, IMO.

If you were to entertain the two hypotheticals, what would you think?
Are you still doing it? No offense but it doesn't seem to have had a tremendous effect besides making you feel better, which in and of itself may be totally worth it for 7 minutes of work anyway. Regardless, the only reason I say this is because I don't think that this is a good program, and I think the science around it is short sighted and not very well carried out.

The major problem is that the studies are not nearly long enough. The human body can adapt really well, and these exercises don't really provide any meaningful level of progression (besides just doing them more). As a user of this program continues, they will have to keep adding cycles, and eventually they'll just be doing it an hour every morning.

As a way to trick yourself into the habit of exercise I think that's great. But the concept that 7 minutes a day can really make you healthy is kind of absurd. There is no question it's better than nothing (especially for people who are already significantly overweight), but it's too bad it's not being sold as an intro to exercise program, rather than The Only Thing You Ever Have to Do Ever.
I don't think I could ever fully trust a company that uses every scrap of personal data they can find to target ads to me to also be my privacy trustee on the web.
Bloody hell, so Facebook is basically crowdsourcing facial recognition a la Mechanical Turk by making it a mandatory part of the login process, and calling it security? That's diabolically clever.

When will Amazon get out of the hardware business already? The Kindle Fire? Awful. Fire Phone? Awful. Whatever their TV box is? Well, jury is still out, but...

Amazon excels at many things, but they've demonstrated that hardware (well, actually, primarily the software that runs on the hardware, but still both) is a huge weakness.
A little idea called Room
The hyrax. A very cute animal that can scale sheer rock faces.
Given the ordering of the process, that makes sense. I'm not a Verizon customer but I would be gone yesterday if I were after reading about this.

As I understand it, they offer an "opt out" that doesn't actually opt you out of this.

Truly gross behavior, though.
All of these explanations remind me of this: http://www.joe-ks.com/archives_may2011/HowToDrawAnOwl.jpg
They need to be publicly attacked for doing this. Only massive embarrassment will change the behavior. Maybe get some politicians involved if there are any they haven't bought yet.
I am genuinely surprise at how confidently you (quite wrongly) diagnosed my problem.

What I did mean, was that for my use cases, I found Mathematica was superior to the alternatives. You are welcome to think this was because I was lazy or misguided, but it was definitely not because I liked not having to specify domains for my variables (and I do remember having to write Assuming[p>0 && x \in Reals, ...] and the like often, it definitely does not assume everything is a positive real).

One thing I used Mathematica a lot for was numerical integration of ODEs (that had been derived using the CAS part of Mathematica and had some pretty nasty coefficients). NDSolve in my experience was just better than competition. You can definitely get nonsense out of it, but with a modicum of care it works incredibly well.
Notably: the exact same device ID (X-UIDH) is injected into HTTP requests from different browsers/apps, or browser tabs in 'privacy' or 'incognito' mode. Also, if you're using 'personal hotspot', any HTTP traffic from a connected desktop/laptop sharing the mobile data service also gets the header.

So VerizonWireless is allowing third-party sites to correlate all HTTP traffic from one device to a single identity, even if you've taken explicit steps (like 'incognito' mode) to try to thwart this, and even if the mobile OS has compartmentalized apps away from seeing each others' identity data/cookies.

Only HTTPS and VPN traffic is immune, and as far as I've been able to find out, there is no way to opt-out. (None of the VerizonWireless privacy settings stop the header from being injected.)
I am sure there lawyers wear $5000 suits and made damn sure the contract is confusing as hell and lawsuit proof.
If I remember correctly from a BBC documentary it's important to have a warm up session first before you do an intense workout like this, especially when you're just starting out. You don't want to risk injuries. Be nice to your muscles, tensons and joints: damage can be permanent, I know from experience.

Here is a discussion of up-gunning main battle tanks to 140mm guns to keep up with advances in armor.

http://z4.invisionfree.com/NSDraftroom/ar/t1514.htm

A few interesting points:

Larger cannon are going to be harder to protect. Computerized weapons that can directly target cannon from sufficient ranges could severely degrade a force with conventional main battle tanks.

The cost of logistics can be related to as the eighth power of the tank’s weight (for a tank of the weight we’re discussing). Therefore, the logistics slice of a 80 ton tank would be roughly 5 times greater than an existing 63 ton tank!

O(N^8) is nasty! A technology that can get one out of an arms race involving such unfavorable scaling would be game changing.

If remotely guided/autonomous surveillance and munitions vehicles could be made that out-range main battle tank weapons, then stealthy carriers of such weapons would rule the battlefield. This, of course, comes with the caveat that another arms race of countermeasures could ensue. It's hard for me to envision countermeasures that aren't themselves vulnerable to purpose built missiles, however.
I did not see the posts that were deleted, but so far nothing I've seen in this thread seems like trolling.
> As a way to trick yourself into the habit of exercise [...]

I heard something about this, only in the past few months, but I can't remember where. Apparently, the way to create habits is to trick yourself by doing something almost ridiculous or trivial. For example, say you want to start flossing regularly. For a lot of people, this is a tough thing to make a habit of. The suggestion is to just floss one tooth, once a day. Don't even try to floss two teeth the next day. Just keep flossing one tooth every day and try not to think about starting a flossing habit.

And then, one day, so the suggestion goes, you'll just go ahead and spontaneously floss all of your teeth and continue to do so in the days after that. You've tricked yourself into the habit, because you had no conscious resistance to committing to flossing one tooth; and in the meantime, by flossing that one tooth, your subconscious built the habit. Once the habit was firmly in place, your conscious brain no longer had any resistance to put up.

Something along those lines is supposed to work for exercise, and many other things as well.
I am sorry if I am too frank here, but the landing page (https://taiga.io/) is just really, really bad.

Not only do the elements not respect their visual boundaries, the whole layout is cluttered, the typography a mess, the color palette is rightout ugly. Shudder.

This is very much a case where less would be so much more.
I really do hope the design is not an indicator of what I should expect when actually looking at your codebase.
I'm not interested in any of these products but here's my impression:

- Kindle Fire initially fulfilled an unmet market - Android(y) tablets for less than $200 that weren't total garbage. When the Kindle Fire launched, there were none. Tablets cost $300+ unless you were satisfied with some terrible off-brand tablet.

- The Fire phone. Total flop. Total miss. They offered nothing to the average Android phone user that wasn't already available, often for cheaper. Amazon has been giving the milk away for free and are now reigning in their services (which is why there's no Amazon Prime for Chromecast, for example).

- The TV. I think it's sleek looking and competitively priced (with everything but the Chromecast, cough, cough). You're basically throwing a dart at Apple TV, Roku, Google Player and the Amazon TV product, though.

I welcome anyone to the hardware market, primarily because the competition will drive this and frankly we have some dismal options outside of phones. Anything that can drive innovation (and prices downward) sounds good to me. Flops will happen along the way. Companies will try things and fail magnificently and that's ultimately good for (almost) everyone.
Agreed on the benchmarks – that's the next (and last) part on the list I'm going to do with this series.

And yes, of course, at some point, constant factors break into applications. Would it be better if add in a short comment on "practically O(1) for non-HPC applications", or would you phrase it differently to give it better context?
I disagree about the Kindle Fire, it is still the go-to cheap tablet device for non-techies (which is most of the consumer market). The high end tablet market is dominated by Apple. Everything else is a rounding error.
Technical Analysis of the SandWorm Vulnerability (CVE-2014-4114)
And for the non-metric... he went less than a 16th of an inch above a globe about a foot in diameter. It's amazing how thin our shell of sustainable atmosphere is.

There was a lot that annoyed me about the RedBull promo jump, a whole lot, but the most annoying thing is how they misrepresented his view using fisheye lenses to make it look as though the horizon curved radically for him. They wanted viewers to think he was in outer space, in that regard.

If you watch the RedBull footage, you can see when this phony effect gets turned upside down when he was upside down; in that case the earth curved radically the other way.

Interesting. You may wonder how a calculation could generate different results when run twice on the same arguments (assuming no obvious flaws such as global variable usage). I once tracked down such a bug when calculating with bignums in an open source program. I don't remember the details, but it was something to do with garbage collection, perhaps not protecting part of the data from getting collected so that it randomly became corrupt.
Can't we just appreciate that both points of views are helpful? Instead of thinking that one is better, and saying that therefore, the other sucks.

Both of them explain different things. The "it's just a basis transformation" makes invertibility, additivity, etc. obvious. The spinning function things makes it clear why we want to do it and what it means to say, approximate by only the small frequencies. (The basis thing tells you nothing about why looking at just the low coefficients is helpful, sometimes. A basis doesn't care about ordering)

Except for orientability, I guess.

Chrome browser, Gmail yes. Chrome OS, Google Apps, Android since 2013... I must be missing something.
Apparently, people are very sensitive about this topic.
I believe that they did release a fix for it after they figured out what the vulnerability was. I don't have a source at this time, though.

Can't help quoting a little more to give an insight into Buffett's character:

> Though 1979
was moderately profitable, the business thereafter consumed major
amounts of cash. By mid-1985 it became clear, even to me, that
this condition was almost sure to continue. Could we have found
a buyer who would continue operations, I would have certainly
preferred to sell the business rather than liquidate it, even if
that meant somewhat lower proceeds for us. But the economics
that were finally obvious to me were also obvious to others, and
interest was nil.

> I won’t close down businesses of sub-normal profitability
merely to add a fraction of a point to our corporate rate of
return. However, I also feel it inappropriate for even an
exceptionally profitable company to fund an operation once it
appears to have unending losses in prospect. Adam Smith would
disagree with my first proposition, and Karl Marx would disagree
with my second; the middle ground is the only position that
leaves me comfortable.
At work I was trying to set up VPN access on a few busses we have. We tried using a Verizon device but couldn't because Verizon puts you behind their NAT. It costs $500 to get out from behind it. I guess this is why.
Hooray. That whole thing was absurd. They hyped it like it was the first moon landing.

Debugging a hang: Chasing the wait chain inside a process
My wife and I do a full clean out every year. Our key phrase is "Be ruthless". Some things are obvious tossers, some are obvious keepers, and if it comes to a discussion usually just saying "be ruthless" to the other is enough to force the decision.

It's frightening how much stuff you can collect over the year but also how much stuff you kept last year that you no longer care about.

I've wondered why most existing LALR(1) parser generators are not replaced with LR parser generators with a higher look-ahead than 1. This improvement, considering that our computational power today does not justify these restrictions any more, would be Pareto-optimal even while it is being decided what completely alternative strategies (PEGs, boolean grammars, parser combinators, etc.) will take over.
The Krstic article is an explanation of the short squeeze that happened near the end. This is just a small part of the Priceonomics article. The Priceonomics article includes a lot more history about the companies and people involved as well as the German politics protecting VW. The Krstic article doesn't even include the twist ending where VW buys Porsche.
Well a Google SVP is not "random", certainly not Sundar Pichai.
Interesting. I was not aware of that notation, thank you.

Re: "all log factors": Agreed, as long as the base of the logarithm is high enough, obviously :). I'm well aware that the base doesn't matter mathematically, but in practice it actually does. Especially since 32 is the number of bits in a CPU word, and thus neatly fits into cache lines, is easily manipulable by CPU instructions, etc. etc. (See Bagwell's papers for details.)
Title is poorly phrased. It should say "how getting on the HN front page allowed us to test our NLP."

The title reads that you performed NLP on Hacker News headlines, which would be more interesting.

I'm posting this here because I'm interested to know what HN thinks about it. I'm involved in an ITIL vs. DevOps correspondence right now, and I found this rather odd (IMHO) video via the obligatory Google search.

I don't feel like he makes a clear argument, although I am leaning toward agreeing with several of his conclusions (e.g. see the last slide).

Edit: I just now found this interesting post-script which says that the presentation was a hit. Take a look. Is this just CA being CA'ish? :)

Median selling fee is 15% from the end price so if you run your own marketing/ads/sales, you can offer prices without this "tax". This pushes 3rd party sellers to either very low margins (especially in electronics) or higher prices on Amazon in exchange for discoverability and no need to run your own SEO/eshop/marketing etc.

what?! unless you're really in top shape and have done a lot of leg conditioning and weight lifting there is NO WAY that you can do a wall sit for 30 seconds straight!

most people, even in good shape (not overweight or obese) can only do 10-15 seconds before their quads burn into a cinder

try it! its a good exercise but 30 seconds? c'mon!

also, another reason why this suggested 30 seconds duration is bad is that it will mean that most people who do try to meet the unrealistic 30 second duration will collapse down as their legs give out and this is NOT what you want to happen because risk of injury from this exercise is greatly increased if you don't get out of the position by standing up
Patents get a bad wrap. This court decision from 2011 describes what may be a clear cut example of a patent protecting its inventor from malicious business practices.

Care to cite that?

I could find no source that Eric Schmidt is claiming that.
A mass sighting with hundreds of photos, videos, eyewitness reports and maybe even physical evidence would be difficult to dismiss. Not necessarily evidence of aliens, but certainly evidence of something.
Statements like this are really easy to make when you have money to support your family. I've often said "I don't want to work for someone who does [x]" then taken a job for someone doing [x] and a lot worse because when push comes to shove, I needed the money.
OK, I'm curious about how well this explanation works for you. I came up with it, and I want to know if someone like you thinks it's any good:

The Fourier transform is usually used to flip from the time domain representation to the frequency domain representation.

"Time domain representation" means when you plot that information, the x-axis is in units of time; seconds or fractions of seconds, usually, for something humans can perceive as sound. The line tells us how loud the signal is at a given instant of time.

"Frequency domain representation" means when you plot that information, the x-axis is in units of frequency; hertz or kilohertz, usually, for something humans can perceive as sound. The line tells us how loud the signal is at a given frequency.

Here's the bit about basis vectors: The frequency domain representation is possible because we can make any graph by adding enough sine functions, assuming we're allowed to do things like increase or decrease their magnitude, increase or decrease their frequency, and shift them left or right relative to each other (adjust their phase).

Therefore, we can describe the graph were interested in using only sine waves, which are pure frequencies, and when we've done that, we'll know which specific frequencies contributed most to the information we represented in the original graph.

There is, of course, an inverse Fourier transform, which takes a frequency domain representation to the time domain, so we can do things like record a sound (time domain), take it into the frequency domain, remove certain frequencies (typically all frequencies above and/or below some cutoff) by zeroing parts of the graph, and take the result back into the time domain, so it can be played back as a recording.
