If you subtract out deaths due to drunkenness, cars kill less people than bathtubs.

If you remove a major cause of road deaths, road death becomes less common? You amaze me.

my car is perfectly safe and can only kill someone in a hit and run at 100 MPH if, and only if, I get drunk first.

Absolutely false. Everyone is capable of making mistakes, you and I included. You can be a perfect driver 99% of the time, but that one time when you look down because your phone went off, or because there was a noise on your right, or the guy coming the other way has his full beams in your face, or... you're deluded if you think you cannot possibly crash your car unless you are drunk.
I usually ask "Where do we go from here?" or "What does the process look like from here on?" or some such.
My financial analysis skills must be weak but how does a company take a loss every year yet also have $88M in the bank?
Do you cover the purchase and tax liability, or just the purchase?

Also, are you not worried about reporting requirements once you reach a certain number of shareholders?
At least for the drunk-driver, yes. I think I read a while back that they were thinking/musing/planning on installing breathalyzers in cars that could prevent the vehicle from even starting.
To be more specific, Broadcast.com would have likely went bankrupt very rapidly during the period of the dotcom bust (it would have been sold off for a small fraction of the Yahoo acquisition price). Financing would have disappeared, and Broadcast.com was losing as much money annually as it was doing in revenue, that bleed would have gotten much worse as advertisers disappeared.

Yahoo ended up shuttering the business not long after the purchase. They couldn't make it work.

Great article to explain terraform to newcomers. I am extremely excited to move all of my infrastructure to terraform once a few more features have been added. Its a great project, by great people, from a great company.
The US has far more sprawl where people live in suburbs which are a significant distance from the closest restaurant, bar, etc. and public transportation ranges from unreliable to non-existent even during the workday. In most of the country, that's also be paired with high speed limits and road designs which encourage driving at or above the speed limit which increases the likelihood of a crash being fatal.

The default mindset is so heavily dominated by the assumption that you'll drive that the building codes in most of the country require bars to have significant parking available for customers, even if the bar is in a heavily urban neighborhood and the owner would prefer to use the space for seating.
There were a lot of lottery winners who lost everything in the first tech bubble. Mark sold his company for billions then locked in his fortune using put and call options. Pretty smart if you ask me. Though, I do not agree with this article
You get a job at Google or Facebook in part so that you can buy a nicer "two ton bullet" than you otherwise could. No one wants to walk out of necessity, and that will not change anytime soon.
The warriors download items assigned by a central tracker, then upload each item to a holding area. The warriors don't keep items around when they're finished. Also, the current tracker keeps everything in RAM, and can't keep up with more than ~2 million items at once. It would take a major rewrite just to keep track of all the pieces.

P.S. Please run a warrior instance. It comes in a small VM image that you can run in the background all the time.

His point is that Sarbanes-Oxley killed the possibility for small-medium companies to go public (~1B market cap). With less than $1B market cap, the overhead costs of Sarbanes-Oxley compliance are a huge % of revenue.

The only way the shareholders can cash out is via a sale to a larger (idiot?) buyer (Facebook/Google/Microsoft/Yahoo).

Even worse, a lot of these companies don't really have a clear path to revenue or profitability (like Tinder).
Yes, for sure. I catch myself making dumb assumptions based on stereotypes all the time, and I probably miss far more times than those I am aware of. Gender is sort of an "usual suspect" for this sort of thing, so, why not bring it to the foreground? Not implying malice or fault, just "hey, maybe this well-documented bias is influencing some of your judgments". Which was n72's - largely valid and well made - point as well. In general, being aware of common social biases is a bit like being aware of logical fallacies: pretty useful in debugging your thoughts.

In any case, most of my emphasis was on the bias of discounting "soft skills", rather than gender bias.
Is that an actual picture of the twins?

That's taking the long view, and it makes sense. I guess I'll have to find someone who can use my work, and then go die.

Does anyone want a small robotics company?
For the Zetas (and many violent organized crime groups), delivering product is a significant source of revenue, but, AFAICT, its not the real core competency. The core competency is manipulation through application and threat of violence. Delivering a high-priced form of contraband is just a convenient way to monetize that competency.
Propensity and pre-determination are very different things. The whole point of the article is that someone who makes fitness a priority and exercises regularly has better health and fitness indicators than someone who doesn't, all else being equal.

Being active is a choice (for most people). Certainly, some people are more likely to do it naturally, but that doesn't preclude the rest of us from doing it.
That Boston managed to avoid this is a very big reason why I don't have much interest in living anywhere else. In Somerville and Cambridge, I feel exceptionally safe, even around cars.
> If I'm not mistaken, this is how [Google|Facebook|Apple] RSUs work.

For FB specifically, they just pre-sell 40% of issued RSUs. The amount then shows up on paystub as income tax withheld.

There's no extra money to be had on top of the RSU grant - for a global company it would be unfair to treat employees at high tax burden locations differently from employees in low tax burden countries.
Do your homework and get good grades. It sucks, but I'm the only person I know who was like me that pushed to the top.

Compete to win, try your best, and work hard. I went to a junior college before I got into UIUC, then from there I have two amazing job offers (better than Google), that's because I worked hard and blew away people with my work. If you do decide to blow stuff off, or did, it's not too late.

Push as hard as you can now. If you do it through school that works (best), and if you do it on your own you have to be disciplined. Make goals and accomplish them, and in college you have to push yourself to the top.
You're absolutely right. I was aiming for a baseline/ballpark here.

At this scale, redundancy via 3x mirror is pretty expensive. You could likely get away with something like chunks of 12 drives in raidz3, especially if you're planning on having at least a few facilities like this. $1m setup + land + a few salaries upkeep sounds like the kind of thing you could convince a few governments to do.

However, Glacier won't do at all for the live Internet Archive, so it's a question of whether they want this to have live replication or not (if the whole backup is offline, who does your integrity checks?)

I'm actually curious how much it would money/storage space it would require to print the entire Internet Archive on whatever the current equivalent of microfiche is (anything cheap and more permanent than magnetic or optical storage).
Sure! Here's a couple concrete applications:

- Any monoid operation is trivially parallelizable: take the dataset, split it into chunks, combine all the elements in each chunk together, then combine those results together as a final step.

- If I'm updating a row in my database with a monoid operation, I can always 'pre-aggregate' a batch of values together on the client side before taking that result and combining it with the stored value.

- If I store some statistics for every day of the year, I can calculate the monthly statistics very cheaply -- as long as those stats are a monoid.

The monoid abstraction seems weird at first, because it's so dang general, but it ends up hitting a bit of a sweet spot: the rules are just strong enough to be useful for a bunch of things, but simple enough that be applied to all kinds of different situations. You can think of it kind of like a hub-and-spokes thing -- this interface connects all kinds of different data types to all kinds of different cool situations, so you get a lot of functionality with a lot less typing and thinking.
Not so coincidentally. There are more than 30,000 people killed in traffic every year in the United States, and it's the second leading cause of accidental death, according to:

People who apply for YC let themselves be 'judged' because that's what the interview process is all about. This post gives you more insight into this judgement process. So, I would say this post is valuable for people who will apply or intend to apply for YC.
I'm not really at risk of being killed by someone else's bathtub in my daily movements around a city...
It is hard to imagine something more demeaning than having your goodness as a human judged in 10 minutes.

Not many would subject themselves to it, but for the fact that YC is one of the few gatekeepers in Silicon Valley who will even talk to outsiders.
Let's say that my initial filter/selection is less than 100% bullet proof. Now what? Do I pretend that it's perfect? Or do I try to find a very inexpensive way to put a safety net behind my initial filter?
Alright, I tested it and it works well! Good job :)

I really like and appreciate how Seth clearly says that you will need to compile Dart to JS for the deployed apps. Thank you!

For a long time Dart community were awaiting when Dart VM will be finally built-in into Chrome, and it was one of the selling points we often heard - Dart will be natively executed by the browsers. However, I personally don't think it's a big deal. Even if tomorrow Chrome... even if all the browsers tomorrow will be shipped with Dart VM inside, we still will have to deploy compiled to JS version for the next 3-5 years (the same with ES6 btw).

Don't get me wrong, I am looking forward to see Chrome with Dart VM onboard, I just don't think it's critical for real business apps.

I also second @jenscow's opinion, compilation to JS is a feature that has some important advantages. For the last 1,5 year I've been working on a business web app written in Dart, it's deployed into production. Most of the time we use dev channel to get access to the latest features. For 1,5 year we never had an issue caused by compilation to JS. Actually 2 times we had issues reproducible only in JS version, but the errors were in our own code, had nothing to do with compilation process, regular race conditions that had higher chances to occur in JS.
"I would really love to hear your explanation why New York City should be required to spend billions on bridges and roads crushed by automobile traffic for commuters who don't even pay taxes into the repair fund"

They don't. They can stop doing it any time they want.

I don't think the result is going to be what you expect, though, especially now that no one has to live (or even visit) the city to do most types of business.
I'll admit I didn't read the study but the results summarized in this post don't seem very interesting:

The sedentary twins had lower endurance capacities, higher body fat percentages, and signs of insulin resistance, signaling the onset of metabolic problems.

The active twins had significantly more grey matter than the sedentary twins, especially in areas of the brain involved in motor control and coordination.

Isn't this expected to anybody not exercising vs. someone who is?

It would have been interesting to see if there were results beyond the obvious effects of exercising.
If the drugs have the widest popular consumer base, legalization might still be a potent weapon because it reduces the degree to which people who aren't deeply involved in the other things the cartel does are dependent on the cartel and subject to manipulation by them; my understanding is that ending alcohol prohibition in the US -- while it didn't, by any stretch, destroy the organized crime groups that were powered by it, did substantially weaken them for similar reasons.
Why racism is not backed by science
Mutability has to put into context of the whole system, not just a narrowly focused benchmark. We can no longer put synchronization issues aside, that just isn't possible anymore. Correctness (coherency and data races) both on a micro level and macro are more important than raw mutation rates. While there are times when mutation is the answer, it has to thought about carefully.
I'm certainly stubborn, but I'm not the only stubborn one here. Unless you're a biologist I probably know at least as much about genetics as you, so we're working from the same level of knowledge. Look up epigenetics. The real world is not as perfect as textbooks and experiments like to pretend. Additionally, I happen to think a lot about adaptive systems (obsessive levels of thought sometimes) so the idea that systems develop differently when exposed to different stimuli or environments is a given to me. Check this out: http://well.blogs.nytimes.com/2015/03/04/one-twin-exercises-... They took identical twins who had already grown to adulthood together and analyzed differences between the sibling who exercised a lot and the one who didn't. Guess what: they found differences that a genetic analysis would not predict! It's trivial in my mind that two identical twins who grew up in very different environments would look noticeably different due to developmental differences. I don't even know what you're arguing over, I never said faces are not genetically determined, only that other things also affect it. That would be the reason for that "almost" part of your assertion. I'm saying that difference is not negligible, some people look very similar by chance.

A quick search led me to this: http://www.npr.org/blogs/pictureshow/2011/12/26/144282436/th... Close, but not identical.

It's not a difficult concept.
Another trick is hidden dividend accrual for preferred stock. The dividends are triggered at liquidity event, so the cap table you thought you were looking at suddenly gets diluted with a bunch of freshly issued stock which is still senior to common.
I'm not "implying" it. I'm stating it. And it's not a "dependence", it's a blessing. It's given people the freedom to live where they want, far away from the filthy, crime-ridden cities that you appear to idolize.

Living in the city can be fun when you're a 20-something with no dependents. Most people change their minds once they have families. That's why suburbs exist.

And I notice that you didn't answer my questions.

The population density in the United States is far too low to support this.

Increase the population of the U.S. to a billion or so, then maybe it will work.
Almost certainly.

In real time, the brain is processing all incoming stimulus.

In a dream/imagined scenario, you are only processing as much as you your brain is pushing into the scenario.

Your not collecting millions of photons via your eye and interpreting a ball as green, your brain just says "green ball" and moves on, allowing for much faster replays/dreams than real-world experience.
There is a huge difference between "protagonist" and "hero". Shakespeare wasn't making a hero out of Macbeth.
You mean like Hadoop? I disagree, the popular bad solution starves out innovation by sucking all the air out of the room. Easier to decide on the globally bad choice.
Then you look at the cash reserves of the titans (Apple comes to mind) and you see it's not in circulation, which proves there are large sums of liquidity on the sidelines not investing.
He's assuming everything will go to zero. So while his post is about liquidity, he throws in "oh by the way all of tech will obviously come crashing down." Except for the tech companies he invested in, of course.
The tracker would have to manage millions of torrents, and each client would have to figure out which subset of torrents it wanted to download. And there needs to be a mechanism for the server to force a client to recompute hashes from time to time. So I don't see how it's very torrent-like.
Actually, yes. There have been several studies that seem to point towards significantly less benefit from exercise when people don't enjoy it.

Obviously, this is really hard to control for since those who enjoy exercise less are less likely to do it, push themselves, etc.

That's not to say that exercise doesn't help at all, but since many of us are concerned about efficiency of exercise that's an important finding.
It can't no, but the things companies do to create culture can be duplicated to create a culture of their own. We borrowed a lot from the typical startup playbook at Perfect Audience and ended up with a place that was a pleasure to work at, but for its own idiosyncratic reasons unique to PA. The general methods, team dinners, relaxed environment, lack of meetings, hiring good friendly people, are the same, the culture that grows out of that is different everywhere.
Why can't we just have the pilot in a pods/simulators in base and have him/her control the plane remotely? Too much latency?

Seems much safer for the pilot, makes the plane smaller, and there's no worries of G's on the pilot.

Good question on Intercom, alishiu. Here is how we think about this:

Intercom, true to its name, is a really nice tool for 2-way communication with your users. Here's where it shines:

1) Visibility: It acts as a CRM that auto updates - it automatically shows you what each user has done and lets you build rich profiles from their interactions with your app and your communication history.

2) Conversations: Intercom is wonderful at initiating conversations via email or in-app messages based on what your users are doing. You get a granular sense of what is going on with each user and so it's easy to talk with them about it.

3) Handholding: The lines between onboarding, product feedback and support are very fuzzy. Intercom helps you handhold your users through your product, heading off some support tickets before they happen and helping you understand at a very basic level what it takes to make an active, engaged customer.

Where Intercom is not as strong is:
1) Scaling communication for a large number of users: It's hard to have these 2-way conversations with your users as you scale up. You can do some automation with Intercom but building sophisticated business logic based on combinations of events and user attributes is difficult.

2) Mobile: They don't do native mobile push or SMS, both of which are very important touch points if your users primarily interact with your product on mobile or on the go.

3) Testing and analytics: It's very useful to have deep analytics (not just clicks and opens) and a testing infrastructure, including control groups, that allows you to try things quickly. The key thing here is that it is not enough to know how many messages you send to users and how many users took an action - you need to understand how many users took a particular action BECAUSE they got a message.
what's interesting is that this comparison controls for genetics, given that they're twins.
The sub-25M market is dominated by the sub-100K market, near as I can tell. The cost of startups is so low that people are doing stupid things, just like they were in dotcom-1.0, but they're mostly doing it on their own dime.

This isn't necessarily a bad thing, but it has created some pretty extreme weirdness at the low end. A friend sent this "Shaming-people-into-taking-cold-showers As A Service" thing to me a while back: http://coldshowertherapy.com/ (to be clear, he was mocking it.)

It's hard to look at that and not ask yourself, "Is it getting kind of bubbly out there?"
This stuff is simply too complex. Just like there guides that make open source licenses easier to understand I wish there was the same for startup stock options.
They've taken $97.3M before: https://www.crunchbase.com/organization/etsy

Presumably they had some profitable years prior to 2012 or have maintained limited losses.

Either way, it looks like they're gearing up for some big growth in the next few years. They dipped into the coffers in 2014 and will raise a lot of money from this IPO, so they'll have plenty of cash to burn on fast growth. It should be interesting to watch!
> if any city is overly generous it quickly gets swamped.

Is there any evidence that this has ever actually happened? I have a feeling it is one of those lies that get passed around by people trying to score political points.
You can see it easily from the story. Ey's car spun around the road into a concrete wall. Malsch, the drunk driver, had his car stay on the road, just suffering front end damage from hitting Ey.

In all the videos, Ey's car looks absolutely demolished while Malsch's looks like just a rough accident.

> Do you call PG out and assume he is full of shit and doesn't know what he is talking about?

Absolutely. I think Paul Graham said silly things about hacking and painting. I think Paul Graham is utterly wrong about philosophy being just a confusion over meaning. I think Paul Graham at time tends to riff on things he just doesn't know much about.

> outright dismissed as utterly full of shit smacks of, among other things, sexism.

Please show me where she's being "outright dismissed."

Please show me how I could make the argument I made without it being interpreted by you as sexist. Or is the mere fact that I made it about a woman proof of its sexist nature?
