Thanks. I didn't expect that comment to be popular, but I didn't expect that much negativity.

HN people think everything that a rich person does is awesome, as long as he's one of "their tribe". Still, even here, I expected better.

So what's the current record with a drogue chute?

And are you sure the drogue was used during the entirety of Alan's jump? It mentioned that he did a series of backflips and broke the sound barrier during his jump. Is that even possible w/ a drogue?

EDIT: Plus, you seem to harbor some negativity about his achievements. Two things (1) It was verified by the US Parachute Assn, and (2) perhaps this reaction is precisely why Alan didn't seek press fanfare; it's an awesome accomplishment by itself!

Reading my example it is obvious that the facts I state don't support the position that worshiping Thor prevents lightning strikes; reading a position where someone makes statements of fact that sound ominous without certain context, but are benign in-context, it is reasonable to assume that either:

1) They don't know what they are talking about

2) They are being deceitful

Says the guy with the user name toomuchtodo...
Yes; you started at 10, and had a computer growing up to practice on.
True, but the problem is that "valuation" and front page articles about it sends a specific signal, "this company is worth this much", and like you said, we're supposed to trust people who put the money into the investment.

The problem is that no investor is an oracle, and no matter the size of their investment, or what statements they make, can actually make a company have some value until it's sold.

At best you can gauge a company's "value" (not valuation) by their revenue and profit, this is an instantaneous assessment backed by hard figures. And you can make a projection, which is a best guess, of the future value of the company based on period over period growth and some notion on how big the market is. But we also don't know what kind of fanciful numbers were being used.

Suppose my friend starts a company making internet connected toasters. Well everybody likes toast, therefore size of market = humans on earth. No! You'd be surprised at how unscientifically figures for market size are determined.

Here's one I've actually heard for a piece of high-end technical software targeting the Federal government: The U.S. Federal Government employs about 5 million people, if we sell a copy of our software to each employee at $3k/license our market is worth $15 million dollars! And then they're very surprised when the market does not turn out to be that big, and there's a mad last minute scramble to target local government because "there's way more local government than there are federal government".

Remember the Segway? They actually hired a professional consulting firm to gauge market size. You know what was predicted? 31 million units inside of 10 years and 50,000 in the first year. Money exchanged hands for this prediction. Valuations were made based on this work. This was supposed to be a company the size of Apple. How many have actually been sold? Nobody knows, but it appears to be well under 50,000, worldwide.

But people in suits said this stuff! With nice hair and fancy diplomas on their walls! If I can't trust them who can I trust?

I'm not saying figuring out market size is easy, it's hard. So hard that it's wrong far more often than it's right (something like 90% of businesses fail). "Valuation", of which market size should be a critical component, is misleading and not particularly meaningful. And the problem is that we take unmeaningful words like that and turn them into major news.
>Do you know anybody who makes purchasing decisions based on how high a score a game reviewer gives it?

Not personally, but the stories that the press chooses to report absolutely has an effect on purchasing decisions in the aggregate. I'm not cool with people like Zoe Quinn using their incestuous relationships with the press to get a leg up on other, more deserving indies. You know, people that make good games instead of harassing suicidally depressed people, intimidating photographers, attacking other feminist organizations for competing with her charity, getting "The Most Expensive Game Jam in History" canceled over personal drama, attempting to censor controversy with DMCA takedown notices, and just in general being a professional victim.

Corruption should not be tolerated anywhere, so I'm happy some people actually give a shit and are taking a stand for once instead of forgetting about controversies the next day as usual. I can see people here being upset that others are putting more effort into GamerGate than they do into much more deserving causes like fighting NSA surveillance, but you don't get to choose what people care about.

As for why others care, I guess it's part being tired of being one of the internet's punching bags, part being tired of Silicon Valley yuppies and trustafarians complaining about the "privilege" of a bunch of roughly lower-middle class youth, part seizing a chance to strike out at the loathsome "clickbait" media that everyone else on HN would be condemning in any other scenario, part not wanting to see video games become yet another medium neutered by the cultural marxist PC police, part spite, and part breaking out the popcorn as they watch the other side make complete asses of themselves on blogs and twitter. The last reason is my favorite, it's absolutely hilarious how vile and hypocritical some of these people are.

EDIT: As I've alluded to, I think GamerGate is the start of something akin to the Occupy movements for the left, or the Tea Party movement for the older right. They begin with a frenetic spark, and it can be hard to discern what "they're about," and sometimes people do bad things in their name, but you have to look past the surface to see there is a meaningful sentiment being expressed. Give them time to find their voice and remember that many positive movements had a rocky start.

Maybe being sensational is unnecessary, but risk taking is absolutely necessary for science. Recently on HN: the story of John Paul Stapp, the fastest man on earth [1] [2]

Sensationalism, while perhaps strictly unnecessary, is inspiring, and that is very good for science. Anyway this jump was positively muted, especially compared to the publicity that Felix Baumgartner's jump got. Some attention is necessary; how else are we supposed to know about great feats people have accomplished, scientific or otherwise? Aside from news articles about the jump itself, there is a very informative website about the goals of the company behind this jump [3]

(I used to work at Quora, my opinions your own)

It's a bit early to say, but I don't think this directly competes with Quora. There have already been many peer-to-peer connecting Q&A services like Aardvark and expert networks like Pearl, as well as lighter social friend/friend of friend Q&A like Jelly.

What Quora purports to provide that these don't is a (mostly) permanent corpus of knowledge that is available later. One to one Q&A is definitely great for getting you an answer to a specific question now, but it doesn't give you a broad picture for things that aren't as laser focused.

A lot of the "personal experience" content on Quora is pretty good, like what it was like to be in the WTC when 9/11 happened. This is of course not the kind of thing an individual needs to connect to another individual to find out (though it's still interesting), so I think that Fountain (the app referred to in the article) will have its own niche that is very distinct from Quora's.

Things like Fountain and Pearl are useful for individual experiences, and experts will make decent money if the platforms are successful, but what you end up with is the monetization of repetitive questions, rather than a resource where you can access a variety of answers for questions. They tend to be a place people go to ask specific legal and medical questions, as well as things like home care/maintenance, but outside those fields they can be a lot less useful.

i.e. color coding is necessary because math notation is typically expressed with ambiguous assumptions in service to absolute terseness.

As far as I can tell the only time it's attempted to combat this is in proofs.

Note that in a real paper or textbook, such a detailed description explaining each term would most definitely be absent, even without the color coding.
Sometime in 2013, before the bitcoin prices exploded, I downloaded some bitcoin historical price data and ran symbolic regression on it with Eureqa. It came up with a formula that fit the observed data fairly well, and wasn't very complicated.

But when I extrapolated it forward a few months, it predicted the price would explode to unreasonable levels. I was disappointed and threw it away, assuming that it must be wrong.
Correct. Most arguments seem to assume that FTDI is either 100% responsible for damaging hardware that doesn't belong to them, or 0% responsible. Clearly the company itself assumed the latter position would prevail in each and every jurisdiction where people use computers. I don't know what sort of drugs they had to take to arrive at that conclusion, but I don't want any, thanks.

One big problem is that civil courts in the US do not work that way at all. FTDI could easily be found 5% responsible for an enormous judgement.

I really like Nest's products. They also own DropCam which makes good if a little overpriced IP cams.

One big disappointment was that when Nest purchased DropCam they shelved Dropcam's then up-coming "Tabs" which were security sensors which communicated to a DropCam and you could receive alerts via their hub[0].

Honestly in the rush to home automation it really feels like security has been ignored. Traditional security companies charge too much and their products are antiquated ($30/month subscriptions anyone?).

A lot of people aren't comfortable with IP cams in their home for obvious reasons. They would be more comfortable with motion sensors which connect into a hub and allow you to receive push notifications when they're triggered on a schedule.

I know for an elderly relative I wanted that exact setup. She was uncomfortable with an IP camera in her home (which is reasonable) so I was looking for a single motion sensor which would send me alerts so the same thing could be accomplished without invading privacy.

Home security is ripe for disruption.

Maybe because most people here never ever change their SIM card. You buy a phone and you're basically locked into your carrier until your contract expires, then you buy a new phone because it's the only way to justify the ridiculous monthly fees. If you venture overseas you often just put up with the stupid-high rates your carrier will charge you because it's too much of a pain or too complicated to call your carrier and get your phone unlocked.

I don't think saving mm's off the thickness is a factor at all because the SIM is still replaceable. I think Apple thought it was a better user experience to be able to choose their carrier this way. And of course now they don't have to stock iPads with carrier-specific SIMs.

Yes, they could sell SIM-less iPads, but that would make for a poor buying experience, at least for us SIM-shy 'merkins.

I don't think it's fair to say Quora has failed. This sounds like something different. Whether or not it will work remains TBD.

I do recall having an eerily similar idea for a mobile-based Q&A system at least 6 years ago though, and decided not to try building it at the time, as I just didn't think it would catch on. Things have changed a bit now - there are more smartphones, more 4G and wifi, and people have grown accustomed to Siri and Google whatever, so this might be more palatable now than it was then. But I have to admit, even being someone who's really interested in this kind of app, I am a bit skeptical.

Still, this conversation has rekindled my interest in this area, and I now find myself considering starting on an open-source version of something like this, if there isn't one out there yet.
OK, for some reason all the replies to this post feel it's really important what percentage of the capital the person is personally putting in. That seems kind of besides the point of my argument.

Again, you introduce context-dependance - which is something that you explicitly say you shouldn't have. What AST a <foo> b <bar> c is turned into depends on what priorities <foo> and <bar> are defined as.

This starts to get nightmareish very quickly, at least if you're trying to leave open the possibility of compilation as opposed to interpretation.

Zones are an interesting possibility to solve this, although it doesn't have generality - there's no way to express "zone C depends on zone B and zone A, but zone B doesn't depend on zone A, nor vice versa", for instance.

Good job on shipping.

Can you tell us what is the hardware configuration you are running on as it is holding up well considering a lot of people are trying it out from Hacker News.
So we should all be quiet and listen for the experts to give us guidance? Sounds like the antithesis of hacker culture to me. It also sounds like horribly bad advice based on large establishments' historical propensity (categorically) to act from what they know, fail to react to changing environments, and cover up what might make them look bad.

Yes, this is all dangerous thinking. Yes, this is acting from one's gut, rather than waiting on the data. But when it's my life on the line, I'm going to err on the side of caution. When death is on the other side of the decision, I'm going to be a little more skeptical of other people's certainty.

You are, on the matter of what these notations mean, absolutely right.

This "effectively constant time" claim didn't originate from Clojure, by the way. Scala, which has similar 32-tree structures, used it before then.

In functional programming, binary-tree structures were common for maps and sets (and still are, in Haskell and Ocaml) because they can use comparisons without hashing and can be faster. However, those trees tend to involve ~log2 n bounces, which can become a performance problem if they're very big. People end up preferring (less functional, and less performant due to hashing if your collection is small) hash tables.

The 32-tree structures are great, on the whole. Not only do they offer fast lookups, but the amount of copying that has to be done for inserts and deletions is generally very small.

The "effectively constant" language emerged as a way of saying, "you're not necessarily going to want to replace this with a hashtable at 1,000,000 elements".

Rich Hickey gave a talk early on about this in which he acknowledged the fact that it was still O(log n) time. As he said, constants matter.

The reason people equate O(log n) lookup with "slow" is that they (mistakenly) assume that n ~ 1,000,000 will prima facie the lookup 20x slower than it "needs to be". And that's, of course, false.
I suspect that it’s accurate to a point. Most of the hardware that I use is also limited and/or works through reasonably well-defined interfaces. I’m a software guy, so I’m mostly not trying to plug in hardware that does fancy things. (I will note that it works just fine with the MicroView Arduino I backed on Kickstarter.)

> There are theoretical limits to the upper bound of problem size.

Big O is defined as what happens as the size of the input approaches infinity. You cannot take a O(log n) algorithm and say it is effectively O(1), that is not what big O means. If anything, you are arguing for why big O notation is a bad measure for the efficiency of an algorithm, not why you can call a O(log n) algorithm O(1).
