Maybe it's my pseudo-math background talking, but I find them relying heavily on a concept of center mass to be a cheating. They basically make very convenient assumptions about the CM that, while intuitive, still need a proof of correctness.

Weekly Digest 15 - The most interesting links from programming community
We ourselves don't know the percentage owned by founders.

Isn't it almost always going to be the case that the founders got diluted by the same proportion as you did? In which case, based on your comment below of YC being diluted from about 6% to about 3%, presumably the founders (who started out owning almost all the stock) would now be around 50%.

I feel like I must be missing something obvious here.
I was there at the site in 2010. It was an amazing trek (http://roopkund.com/).

Right now, the forest officials are struggling to preserve the remains because tourist often like to take the skeletons back with them as souvenirs. Since the lake is far off and frozen for eight months in a year, it is difficult to guard the area. Most skeletons and bones have been stolen over the years with only a few skulls and bones remaining around the frozen lake.
There are a great many people who benefit from roads indirectly via the services and commerce they provide.

Not all market transaction systems are effective at capturing sufficient amounts of consumer surplus to make provision of services possible.

As another example: many private (and public) transit systems were funded and financed by retail and real estate interests. By covering the fixed capital and much of the operating expenses of bus, trolley, and rail lines, they increased demand for their products and services. You see this today, but it comes in the form of providing "free parking" for retail establishments (you think those acres of parking outside your local mall or WalMart don't cost anything?).

Markets have failures too, my friend.

These new services simply make the regulation and taxation issues more and more obvious. You can't stop technology, you can't stop innovation. Once you acknowledge that, you realize that laws have to adapt to new realities.
> But when programmers talk about “regular expressions” they aren’t talking about formal grammars. They are talking about the regular expression derivative which their language implements. And those regex implementations are only very slightly related to the original notion of regularity.

That's why we call those derivatives "Franken-xpressions". They can take exponential time in the worst case. See "Regular Expression Matching Can Be Simple And Fast (but is slow in Java, Perl, PHP, Python, Ruby, ...)" (http://swtch.com/~rsc/regexp/regexp1.html).

The additional power of Franken-xpressions comes at a cost.

For general purpose parsing, I suggest using a parser combinator library.

I couldn't dig up the original article, but I wouldn't be too surprised if the images were in fact millimetres in size.

The images are of electrons scattered from hydrogen atoms, directed onto a plate by an electromagnet. The scattering almost certainly has a lens effect, similar to shining a torch at a mirror ball. From the article:

the team fired two lasers at hydrogen atoms inside a chamber, kicking off electrons at speeds and directions that depended on their underlying wave functions.

A strong electric field inside the chamber guided the electrons to positions on a planar detector that depended on their initial velocities rather than on their initial positions.
Interesting. I agree with most of what you said. AirBnB is relatively new, laws have not yet been efficiently enforced, so some costs are being offset on neighbours/cities.

But I'm not convinced that a) the costs are currently so bad it requires market restrictions on AirBnB-style units and b) this a problem that the courts, cities and property owners can't handle on their own - by adapting to change.

Whereas the incentives to add restrictions on the basis of protecting existing industry incumbents are very clear.

^ That motivation which so often dictates modern government policy is the basis of my villainization. Once again I see the opportunity for real economic/social benefit via technology and opportunities to address this without restricting technology or markets (such as an evolution in property law and defence).

Instead I see a government rushing to add new policy, without a clear indicator that they are being representative of the best interests of their citizens ... or even themselves.

This same narrative has repeatedly recurred a hundred times in the tech scene (copyright, wiretapping, unlocking phones, etc). As long as the state refuses to even attempt to evolve along with technological change and takes the market incumbents interests first, then you'll keep seeing these posts.

I think this is a different, unrelated article.

In the experiment you linked to the researchers managed to force an electron into a huge orbit, on the scale of millimetres. In the OP's article they are imaging normal Hydrogen atoms.

It's very interesting, but unrelated as far as I can tell.

There was a tornado near my village in Belgium (Hardly the land of freak weather) which was preceeded by a hailstorm. The hail was only about an inch across or so.

After the storm and tornado had gone through and we were outside evaluating the damage a man staggered into the village. He had been out jogging (Shorts and T-Shirt) when the hail fell and it looked like someone had beaten him all over his body (loads of individual Bruises, bleeding etc.).

And this was only relatively small hail in the grand scheme of things. I can easily imagine hail being able to kill someone.

I met one of the founders around 6 or 7 months ago.

Honestly I felt like he was the first founder I'd met in NYC that wasn't a bullshitter. He was straight forward, and actually helpful.

Those guys have been working on Rap Genius for years and years -- before anyone in the tech industry had heard of it. They made it because they wanted it, and the site grew with the community.

They silently built an internet empire and didn't care about PR stunts or hype until they had REAL traction (because that's the only thing that really matters)... Which is a lot more than I can say for most NYC startups.

Honestly, I think there's so much potential in the idea -- it's a rocketship. If you're an engineer in NYC looking for a job, you should hit them up.

The same geopolitical goals The Atlantic has every night, mc-lovin. World domination.
AirBnB may be the canary in the coalmine for tech, maybe more than the privacy issues surrounding the majority of the current tech business models.

The industry idolizes "disruption" without taking any responsibility for the negative side-effects. However, in the case of AirBnB, these side-effects don't just affect an incumbent industry, but the private lives of completely innocent ordinary people, who live in the same buildings that are used as makeshift hotels.

Illegal and semi-legal subletting is a big enough nuisance as it is in major tourist destinations (I live in one), and AirBnB is making the problem exponentially worse.

A similar narrative applies to the presence of Uber in places with a decently regulate taxi system.

Not all disruption is good.

Great idea! I was thinking about using accelerometer as well. It'd be cool to track reps and try to beat personal record.
I can't help but feel that you didn't fully understand what the grandparent post said, so let me take a whack at it:

First, human trafficking is illegal, but (apparently) very profitable. It was an unstated assumption that those people who engage in these sorts of activities do so primarily out of a motive for profit. In other words, that human trafficking could be largely eliminated by making it unprofitable.

In order for traffickers to enjoy the considerable fruits of their (slaves') labors, they need to invent a plausible-seeming and, more importantly, legal source for their wealth. This is called money-laundering. To do otherwise would invite the attention of the local constabulary.

What the GP is suggesting is that a viable means to curtailing human trafficking is to make money laundering difficult. This makes it difficult to use the profits of the crime, which reduces the incentive to commit the crime in the first place.

Having sources in Amazon, I can tell you the goal here is not simply to deliver Groceries but rather to find a way to remove FedEx / UPS / etc from their cost of goods sold.

The economics of Fresh are very poor for Amazon and likely will always remain so, unless they can start to leverage it for same day shipping of the rest of their product line.

It's not something Amazon likes to discuss too much as it has the potential to upset their partners significantly in this space.
So arguably at least one of {pg, pb, etc.} could have made just as much value over the past ~10 years by starting another startup, instead of an YC, if that were the goal. 10 years is probably enough time to try/fail-fast at least 2 and maybe 4 times, each.
What is the fastest algorithm for multiplication of two n-digit numbers?

What is the fastest algorithm for matrix multiplication?

I think those "What is the fastest" questions are relative. In my opinion, they are not unsolved problem. There are already solutions for them. And in those current solutions, there is of course the fastest.

When a faster algorithm is formulated, a time will come where another algorithm will perform much better.

EDIT: Now I get it. That "fastest" is in terms of time complexity. Thanks guys. :)

The rent controlled tenants below me pay about $800 for a unit that now rents for $3200 a month. Last year when they bought a home they decided to keep the apartment to use as a pied-à-terre and rent it out on Airbnb.

I found out about this after having three different people in a weeks time knock on my door and ask me where the fuse boxes are. Not a huge deal if my neighbors do it, but these are total strangers. At least when someone moves in to my building they have multiple background checks. And since full time residents live here they have a reason to be polite as they see me daily. They have some connection to the building and its residents.

A few weeks after the start of this I was woken up at three A.M. by my dog barking at the fire escape. There was someone on the fire escape looking into my bedroom window! After calling the police I found out that it was a renter from the unit below who wanted a better view and decided to peek into my unit at the same time. This has happened half a dozen times in the last year.

I work typical business hours. People who stay in the unit as guests are generally on vacation and this can lead to loud parties that last all hours of the night. I have a few neighbors who work strange hours and we work out noise agreements, you can't do that with people who are staying one or two days.

There's also the moral issue. It's hard to find a place in San Francisco, what they are doing is illegal, against the terms of their lease (it's very hard to evict tenants in San Francisco, the owners are trying), and they are denying someone a full time residence so they can make extra cash.

I like the idea of Airbnb but I agree that the people who rent units need to be held to some standards. A permit that neighbors can contest seems reasonable if it's going to affect their standard of living.

I've found it in both the second edition and the seventh, both asking for just the 4-block case.
I was at that shareholder meeting, and Bezos was answering a question about the future of Amazon Fresh asked by the only other person under 30 in the room of 100.

Bezos didn't make any pronouncements with his response. Instead he praised the Amazon Fresh business so far, disclaimed progress against inherent difficulties in that market, and said out loud that he continues to believe in the business and management. There was nothing else to get out of his answer, and any reporter or other 'source' reading into that quote is speculating.

For context, Bezos also said he is optimistic about AmazonLocal and said similar positive statements when asked by an elderly woman who uses the service. I happen to know that the team supporting Amazon Local is much, much smaller than it was a couple years ago. Reducing headcount isn't what I would call optimistic, but Bezos was doing the right thing and saying positive platitudes at the shareholder meeting.

Two other people asked Jeff to comment on political issues -- one on the prohibition of selling gun parts, and another on selling violent video games. I almost feel bad for the man having to deal with that nonsense.

Amazon may very well be rolling out Amazon Fresh elsewhere or using the same infrastructure for same-day -- who knows -- but Jeff certainly didn't make any announcement or hint at the shareholder meeting.

Not optimizing for money is setting yourself up for long term sadness.

I'm not saying work for minimum wage. Money is obviously a component to happiness, because while you can't buy happiness, it's hard to be happy when you can't afford to eat. But you probably don't have to hit 100% of your maximum earning potential to avoid starvation-induced unhappiness, which is why optimizing for money is not my approach.
As a side note, there is no way in hell hotel prices in Quebec reflect their fair market value. Hotels are about the same price in Chicoutimi where land is vastly abundant as they are in Hong Kong, a tiny overcrowded island. My gut guess is that real estate prices are at least 10x higher in Hong Kong too. It's very hard to find an apartment below 1000$/month in Hong Kong whereas in Chicoutimi you can find one for 2-3x the price of a night at the hotel. Makes no sense at all even after considering the cheap imported workers hotels in Hong Kong have access too and other economies of scale associated with a densely populated area... Disclosure: I was born in Quebec and have lived in Hong Kong.

Um, why exactly can't Airbnb help its hosts abide by the laws?

It's a $250 tax. It does not exactly seem onerous to have them provide a reminder and a simple 1, 2, 3... list of how to make sure that they are legal in the area they are hosting in. Maybe even a way to pay directly as part of signing up.

In this instance, it's really not the law that needs to adapt to reality, it's airbnb.
Is it really possible? I believe the "fastness" of something is infinite because of numbers being endless.
The idea is that by taking the other side of the bet, you are incenting your counterparty to do the crime. The bet is essentially an offer to do murder.

If you bet me you'll kill Mullah Omar for $10k tomorrow morning, I'll max out a credit card to be your counterparty.

By being specific about the time/place/manner of death, you can avoid the free riders to some degree. At least, all the ones who weren't betting on you specifically. If I find a killer credible, I'd

The whole point of structuring it as bets vs bounties is plausible deniability. A person contracting for an assassination is looking to lose money and gain dead Mullahs, whereas a killer is trying to trade Mullah killing for money. Uninvolved speculators are just betting based on the credibity of specific proposed-killers, I think. It would be easy for killers or contractors to manipulate the market to throw them, I think.
