Congrats to the Mixpanel team. They have always been very supportive when we've had questions. When we had a problem with a particular statistic a few months back, they actually came on-site to diagnose.
Ugh yes. I almost always dress up from tshirts+jeans due to a myriad of reasons (for one, tshirts aren't usually designed to fit boobs on the bigger side), and I've gotten negative comments as a result. I don't dress like a geek so I must be a wife/gf/non-tech person (one guy at defcon called me a slut...), I dressed like everyone else, I must be sucking up and trying to get "in"... can't win.
> A hospital can charge you for anything and you're legally obligated to pay it.

Categorically, unequivocally wrong.

Hospitals cannot just make up charges. They cannot bill you for procedures/tests/services you did not receive (and if they do, you are not "legally obligated to pay it").

I know the anti-US healthcare circle jerk is pretty strong here, but we don't need to just make things up in order to prove a point.
>I've always been a "more the merrier" sort when it comes to meetings. Does anyone else have some insight on #1?

I've always felt that with too many people it's hard to get anything done. Getting consensus and keeping the meeting on task and driving towards a resolution can become harder the more people that are in there. Too many cooks and whatnot.
Four Reasons Why Offline Netflix Viewing Won't Happen
This was great honest advice I needed to read. I'll check out the budget software too. Thanks Andy.
Obviously not marketed towards California.
We tech folk would do well to remember that relatively few people have the good fortune of working in a labour market where demand outstrips supply. Being able to just quit with a comfortable buffer in the savings account and confidence that a better option is just around the corner is a rare privilege.

In a market where there is an oversupply of labour, a free-market race to the bottom results in significant suffering over a large number of workers while benefitting a small number of the already-wealthy. It is difficult to view this as a socially desirable outcome.

A Breakdown and Analysis of the Sony Hack (December 17 Update)
Cutting out SDK Complexity: “making HTTP APIs available as self-contained procs”
Mixpanel helped Mixpanel get their $865M valuation. Mixpanel is solving a huge problem with a bunch of software, gobs of data, and smart people. Beyond that, they're pulling in revenue. Regardless of how good, or how brief your deck is at the end of the day your value comes down to your organization, your ability to execute, and your future revenue potential.

I'm not going to say their deck doesn't have value, but I will say it doesn't seem like it has much of one. Maybe that's the point.
They have the malware and the malware basically wrecked all of Sony's Entertainment. The reason why everyone keeps saying it was a disgruntled employee was because unless someone spent a lot of time gathering information on Sony's IT infrastructure, unless you didn't in which case you would need intimate knowledge of the infrastructure.

The timeline for North Korea doing this or hiring someone to do this is off. They would've had only 3 months to put together the project.
I find that very difficult to believe. Also, what do you mean by "many" ?

because you're asking: I downvoted your org comment after you claimed the sony hack was a pr stunt, or seemed to be saying that anyway, after that I stopped voting bec it the whole thing seemed to have devolved into a pissing contest.
This is a terrific deck (and thank you guys for open sourcing it, even in redacted form - an excellent compromise that's totally fair.)

Take note of a few things:

* They don't use BS "corporate speak" -- no synergies of optimizing user solution metric analysis.

* There's no fluff. Just, none. Problem. Solution. How We're Doing. Why We're Better. What We Want To Do. The Landscape.

And it worked. This should be the baseline for every pitch deck.
With Sony Hack, Nation-State Attacks Go from Quiet to Overt
Seeing how the Rust community seems to have converged on using `uint` as the default type for array indexing and so on; wouldn't it make sense to reflect that in the complexity of the name of the types?

Instead of (uint, int) we could have (int, sint) or (uint, sint).
This is why I often get annoyed when people post slide decks on HN. The presentation was often really good, and so the slides (being there only to supplement the presentation) make no sense out of context.
Why do you hide your growth rate when you show your graph?
I'll second the facebook-integration idea. I'd much prefer to be able to sign-in-with-facebook and point out which person I want to buy a gift for than have to manually enter information about them (which I probably just culled from facebook anyway).

I think the great utility of your app (which I like very much by the way) is getting gift ideas for people you barely know (coworkers, distant relatives, etc). So I don't know the answers to those questions, but my social network could probably figure it out.
Dominos can do it for Pizzas because the profit margin on Pizzas is about as close to 100% as you can get, and delivery-person pay is about as low as you can get, combined with subsidy via tips. A $20 pizza will have a higher total gross margin than a $100 anything-retail.

Amazon is going to lose money on this, and it will probably only ever be feasible (even as a net loss) in a handful of zip codes in the US.
So in college, you never associated or made friends with people younger than you? You were the last college grad your place of work hired?

Open Kanban – Open-Source Initiative to Create a Kanban Core
While their intent is good, choosing the term "Open Sourcing" is not very genuine here. The pitch deck is nothing stellar (it's a run-of-the-mill pitch deck that we've seen before), and showing the slides only really lends ideas to others (ie. you can't literally treat them like an open source project and just modify certain parts, you have to rebuild the entire thing from scratch, and of course YMMV).

A more appropriate title would of been "Take a look at the pitch deck we used while vying for an $865M valuation".
I have Tile, and I also have Phillips Hue lightbulbs, which I currently have hooked up to email and social media alerts, but, if I felt so inclined, I could easily connect to a weather forecast. Or... I could just have a weather alert app on my phone (I'm sure there are tons of them).

Current technology has already solved the generic version of this problem. What you've done is solve this problem again, but only for a very specific use case, while requiring the user to buy in to a bunch of specific software and overhead that only helps them in that specific use case.
You are going to confuse a hell of a lot of people if you make int mean "unsigned integer"!

Part of the plan is to make it easier for China to spy on its citizens and local companies. Because China will much easier integrate it's local eavesdropping plans into the technology, this will give an opportunity for other countries, using local spies, to piggyback on the spying technology the China uses on his own citizens and companies.
Step 1) Be successful
Step 2) Make enough money that don't you need to ask for money
Step 3) Ask for more money anyways!

So yeah, I agree with you. There's nothing special about the pitch deck. The special sauce is the company, duh. They also got a lot of great free marketing out of this blog post. Their next post should be "open sourcing our blog post that helped us get tens of thousands free views". :)
This is typed in the foreign key constraints DDL.

Often a foreign key will refer to rows in more than one other table. Not all queries will want to chase all of those references.

Moreover, when you have a composite key, the foreign part may only be a subset of the entire key.

For example, if your Key is {Street,House}, you have a relation to another table which has a list of people inside that {Street,House} and you might also have a relation on {Street} to a table that contains metadata about that street as a whole.

The "Type" of the "row in another table" isn't a single thing: it would be different for all the different relations so it exists in the form of foreign key declarations which embody all the variability in the relation.
How to Create Habit-Forming Products (video Course)
Awesome, now I'll just add "replace umbrella batteries" on the list of things I have to remember to do every 6 months or so.
Another big difference between this and Wal-Mart is geography. Wal-Mart's strongest areas are less-densely-populated rural areas where one store can draw customers from miles around. And indeed -- you can't easily set up a same-day Amazon delivery service in rural America. The distances and low population density make it completely impractical. For the foreseeable future, Amazon will compete with Wal-Mart in these areas using traditional UPS-style delivery and larger selection.

But this is going into New York City. And the flipside is that you can't put a Wal-Mart in the middle of NYC -- it's cost prohibitive. So it's not clear that this initiative even competes with Wal-Mart really. And brick and mortar stores in the middle of an expensive city have huge real estate costs, so it's difficult (though not necessarily impossible) for them to compete on cost the way Wal-Mart does.
Nothing but Sets(an Introduction to Sets in JavaScript)
The same could be said by mathematicians about code. They look at a hash map and might think it is cool that you have O(1) lookups, but have no idea how it matters.

With experience and practice with theoretical math, you also learn how to apply it.
There are actually a lot of examples. Presidential privilege is a common example where there is some but not total compliance.
The working poor get shafted in America, but the middle class gets a better deal. They hardly pay taxes, get employer paid health insurance and vacation.

Surely they should all use BLE or similar? If umbrella disconnects (you're outside the 15-25m range), give an alert. If using BLE, the protocol is essentially open and other apps could build around it.
I think a better product would be to create a band you can wrap around your own umbrella that does the same thing. Of course, it could be for anything at that point and that is often more difficult to market whereas losing an umbrella is a fairly normal problem.

Just my (unrequested) two cents.
Wal-Mart has the downside that you have to go to Wal-Mart though. I don't just mean that in the dismissive sense that their stores are unpleasant (which they are), but there's a fundamental mismatch between an urbanizing population and a big box store in the suburbs that everyone has to drive to and lose their car in a massive parking lot.

In fact, Sam Walton knew this. His mission wasn't to dominate the world of retail, it was to bring the same economies of scale urban retail already had to rural communities.

Keep in mind that physical storefronts have costs too. Wal-Mart has warehouses too, and they're probably simpler, but when all you have is warehouses, there's a lot of complexity you can add and still have a simpler, more cost-effective model than employing battalions of people to operate cash registers and stock shelves in thousands of small towns and suburbs across the country.
Interesting they store so little on the device. Does the Band generate a lot of data?
Casual dress code does not include a clown costume, so it's far more constrained than your suggesting.

As to suits it's one of those fractal breakdowns with a lot of varity if you get specific enough. EX: You could say fat vs skinny ties, but the there is a wide range of patterns wich fit a wide range of shirt colors. Not just Red tie on white shirt.

Personally I like semi formal dress codes simply because they have a default and require minimal thought. Where casual has a lot of 'hidden' rules.
I don't personally get the RDS value proposition, but how does it lead to vendor lock-in, much less severe vendor lock-in? I don't believe there is really any lock-in whatsoever -- backup your database and move it wherever you want, whether you're running the pgsql, Mysql, or SQL Server variants of RDS.

That's a bit disappointing. I was hoping to get one of these bands, but to hear them say that all data is stored on Microsoft's cloud is a bit disconcerting.

It is so telling that this guy thinks moral certainty and "fervor" are a good thing. A person who is 100% certain and unquestioning in his beliefs is a person who cannot be reasoned with. This avowed rationalist speaks with the language of religious fundamentalistism.

Thank you.
Not the person you're replying to, but maybe these numbers will help:

- The median household income for 2013 was just under $52,000 [1]
- For that same year, the marginal tax rate for a single person making that income was 25% [2]
- If the household is married that drops to 15%.

Most Americans on HN are very likely upper-middle class in income, since that generally means $62,500+ in personal income and a six-figure household income [3]

I think these income stats are incredibly interesting. I never would have considered my wife and I to be upper-middle class either in wealth or income, but according to every set of figures I can find we're pretty solidly in the top 5-8% range nationally. It can be misleading what "middle," "upper middle," and "upper" really mean if you're strictly speaking about gross income.

It's true that they can't just make up services, but they can do a pretty wide range of things and bill you for them, without giving you the price in advance. My dad was in the hospital once, and got something like 20 separate bills, for different services he had no idea he had received (and had no way to verify if he had even received). And my mom actually did get a half-dozen or so bills for services she definitely didn't receive. She went to the ER, checked in, but ended up leaving before getting any services whatsoever: after >1hr waiting in the ER's waiting room, she started calling around to see if she could be seen somewhere else, and left when she found a nearby urgent-care clinic that could see her. They still billed her for a "standard" ER work-up, including line items for a blood test and lab work! She had not had blood drawn, and clearly no lab work was done. Obviously she didn't pay that bill, though: if you really have good evidence that the service was not performed, you can challenge it.
There's a ~15% payroll tax (income tax by another name) for social security and medicare. The bulk of the median household's remaining income will be taxed at 15%. There's some fudging for deductions, I suppose, but that's also leaving out state and local income taxes.

The point was that a 24% VAT doesn't mean much to me when other major taxes are left unmentioned. It actually sounds like a great deal if income and property taxes are only nominal.

EDIT: You're likely neglecting to include both halves of your payroll taxes.
I've only ever left umbrellas on trains and buses, which this wouldn't be very useful with.

Yes, as a quant.
It doesn't matter if it's a good film. That's why you see marketing campaigns saying 'just try it' - even if the product is crap they still make 1 sale.

The film is getting such incredible hype a huge amount the profits will be in the opening night. Check out the Rotten Tomatoes score: critics are divided on whether it's a good film, but 96% of people want to see it.

If Sony don't release the film eventually internationally, they'll lose money - but withholding it makes it a scarce commodity, drives hype etc.

I'm reading Catmull's book now, which is not an autobiography by the way. From reading that and other sources, I would agree that he was proud of the people but not the company. Jobs looked to unload Pixar more than once and didn't fully support the idea of it being an entertainment company until it was obvious that Toy Story was going to be a hit.

Regardless, I'll never give Jobs more credit on the success of Pixar than Catmull, Lasseter, and others who are the true sources of success for that company.
The Mill CPU also works like that- they have instructions for wrapping, overflow, and saturated add, and the overflow ones generate viral bad values that only trap on store/branch/etc.

Given that it's generating the same bits as x86, but with the flag stored with the output rather than in a separate register, the hardware cost shouldn't be more than one more level to select the actual result.

This is also how they handle illegal reads, which (along with vector smear and pick instructions) makes vectorizing loops possible when they might otherwise cross protection boundaries.
The Linux “Grinch” Vulnerability: Separating Fact from FUD
For the purposes of comparing the effects on the individual taxpayers, it seems fair to me. Structural differences aside, a 24% VAT sounds great if there are no other taxes and there is some deduction or subsidy to counteract its regressive effects.
Omg, what the hell kind of dark pattern is it that waits 10 minutes to start playing an audio ad?

Slashdot's audio ads don't wait 10 minutes to start. Slashdot's much hated auto-refresh "feature" is to blame.

It periodically refreshes the page and brings you a new crop of ads, some of which might be audio ads.

The auto-refresh "feature" merely exists to increase their ad revenue. Nobody I know likes the auto-refresh feature, as it just causes you to lose your place on the page.

Having the ability to pickup and deliver from multiple locations throughout a city like Postmates or Instacart does is a huge advantage. At least for a one hour delivery. Density of drivers in a city is an important factor as well. If you can route a driver to a location nearby instead of a single warehouse you can be more efficient. Instacart and Postmates also both have high frequency categories that they can use to leverage less frequent items, e.g essentials over time and potentially at lower costs.

Paul Revere's observation of events happening and reporting back in his own words isn't a great analogy. A better one would be to intercept all stagecoaches at their midway points across the entire United States, and manually copy verbatim the letters they carry in case one day we want to know what Jack said to Joe.

Yes, the passing of "information" is not new. But I believe the intercepting of mail, copying and then letting the original letter through to its destination without a warrant is illegal. (Isn't it?)
I liked Atlas Shrugged when I read it. But I think if Dagny Taggart would see today's world she wouldn't be too happy as well. While capitalism won over communism the corruption of governments didn't die out it just became more clever.

Most engineering jobs at finance companies are cost-center roles.

I think this will vary based on the size of the firm. Larger firms that trade in multiple markets and in different asset classes or firms that become registered broker dealers will tend to have larger back office operations. Smaller firms will outsource as much as they can so that the engineers are primarily focused on supporting whatever strategy the firm wants to trade.
