It does, but it's a little disingenuous, too. You say things like "The ambulance dispatcher knows our location" - you mean, the location of all the facilities you service" (which isn't a stretch, most EMTs could probably recite the street address of every nursing home in their service area in their sleep).

A dedicated line gets you "Oh, this is Call9".

They still need to get pt demographics. ALS/BLS. The dispatcher still needs to find you an available ambulance. Dispatch it. Get the crews out and on the road.

Yes, the infographic breaks up a lot of that information, but the call receiving time is in many locations mandated to be within 60 seconds of reception to unit toned. And your service doesn't cut that to zero by virtue of "we have a dedicated line to an ambulance service".

And if they don't have that? Because that WILL happen. "Ambulance Co B, respond in place of Ambulance Co A, no units available".

"Call 911." And you've burned that time because you need to go back to the start.

"With a doc there immediately, we can encourage bystanders to do CPR immediately and again save lives not otherwise being saved."

That definitely helps. But is not unique to Call9. Call 911 and you'll get dispatcher-assisted CPR. Counting compressions with you, talking you through the process.
I'm not quite sure these days. This hobby has gotten far more complicated than it was when I started. Ben's blog and The Points Guy are probably the best intros. I'm not a fan of TPG but he writes a lot of articles on the basics.

I've been active on FlyerTalk for about five years—after being in that deep for so long, it's hard to step back and figure out where to guide a beginner.

Plus, lots of it is based on your own financial situation. Available funds, credit score, travel profile.

I would argue that the vast majority of people are best served getting 1-2 cards with bonuses they spend in (I use the Amex Everyday Preferred and Chase Sapphire Preferred) and focusing on those. Especially if you have multiple people to bring along, you're better off with one of the flexible points currencies from Chase or Amex (or Citi, theirs is improving) rather than chasing airline-specific miles.

The exception to the multiple-people advice is hotels, as those redemptions are obviously per-room and not per-person. Hyatt offers the best value IMO but Hilton points are stupid easy to earn. Depends on where you want to go as they have very different footprints.
Wow, there's a market for this? (Such words come before something is canned, or blows up to make millions I guess.)

Can a business really save a lot of money by putting up their employees in "business-ready homes," like a twee Lower East Side room for $55/night that looks like a (very) young woman lives in it?

One would think that the lost productivity in dealing with a different landlord in addition to the often exciting/terrifying moments that come with an AirBnB stay seem to offset the cost of a business rate hotel. Productive employees, also receiving a salary and benefits while traveling, are worth more to me than saving $100-$200/night on a hotel stay.

The only place I've worked where something like this would fly was where "employees" could take some abuse: grad school. Maybe I am now an old soul, but I like boring, dependable hotels when I travel for work.

Google throws its hat into the OpenStack cloud ring
Wait. So Paul Allen was friends with a friend from a wealthy family who sent their son to Harvard. He himself attended a private school.

Sergey Brin and Larry Page were PhD students at Stanford...

Marc Cuban was middle class... in an affluent neighborhood known for the quality of its school district. And the dude was a beast of an intellect and was pushed by his family to be entrepreneurial from age 12. Koum got extremely lucky in being in the right place at the right time in what was essentially the app store lottery, not to mention that he seems like an incredibly bright guy.

Honestly, your arguments are not helping. All these people, aside from being white, working on tech and being extremely talented, were in the right place at the right time. I don't doubt that they would have been succesful in other fields since the common theme is that they're also incredibly smart.

But from all these examples I just can't help thinking that if these guys had decided to, for example, go into medicine, civil engineering, or other traditional paths, or if they had been of a different gender things would have been different.

Also, dude, what part of being a PhD student at Stanford doesn't scream a tremendous amount of privilege? Wealth and class are not just a question of the amount of money in the bank, but also being raised in families from highly educated backgrounds, a culture of hard work, a selection of professions that promote entrepreneurial and technical values, the sheer luck of having chosen a field that's expanded exponentially, and also not having to deal with shit like, say, malnutrition, which is a not uncommon theme in the US, where a significant child population lives on food deserts.

Rest assured, I really, really think that if Brin and Page had been to any other university with a not-so-stellar track record of professors being intimately involved in Silicon Valley corporations, they would have been "merely" very good researchers. There's a ton of people who have the skills to study in Stanford, yet for monetary issues, difficult childhoods, and the plain fact that a lot kids have no idea what CS education is about, they never get the chance to be exposed to the people, and most importantly, the money there.

Typically, cryptographic primitives (like block ciphers, hash functions, KDFs, etc) are written in C. Bugs are caught solely by the use of a sharp mind and careful reading.

There are really two reasons for this: (1) optimization is a really big deal; some impls go so far as to have asm for specific architectures or use architecture-specific features like SSE2 and (2) there really isn't very much code for a cryptographic primitive, typically <=1000 lines. (e.g., see https://github.com/khovratovich/Argon2/tree/master/Argon2i/r...).

Once a simple reference implementation is hand-checked, it can be used to generate comprehensive test vectors for other implementations.

This isn't my area of expertise, but I believe there's some research in applied crypto for implementation verification. I know https://github.com/GaloisInc/cryptol is a language that's supposed to help in that regard, but I don't know offhand who all uses that.

I have a blog where a few years ago I started posting stupid little problems I'd solved.

Usually, they involve obscure combinations of technologies, or using a common technology on an obscure platform.

Some of the things I thought were almost too stupid to bother publishing generate the highest traffic. It's admittedly tiny traffic across the board. But I get a few comments like "thanks, mate, didn't know how to solve this!" which makes it worthwhile.
Maybe, but HN suffers quite as a bit as a forum. It's not really productive to go back and edit a comment to improve its quality. The half-life of even a popular thread on the front page is only a few hours, with a very long tail, so you might spend ten minutes editing a comment you made an hour ago all so that only three people will ever read it.

For better or worse, downvote-to-sort-by-quality is a lot more efficient, and a lot less noisy.

Read this as less of a disagreement with you and more of a criticism of HN as a place for high-quality discussions.
That may be, though code becomes more cluttered with moves as well.

That is definitely not the case.

The system does no such thing. Criteria-based dispatch is a powerful tool. Many counties also require Fire/EMS dispatchers to be trained as EMTs.

Expert systems help ask the appropriate questions to establish the base complaint, and the level of service needed, the response level, lights/sirens, what-have-you.

> The whole point of move constructors are observable side-effects.

Nonsense.

> Furthermore move constructors often have to throw an exception due to the fact that moving an object should leave the original object in a valid state.

Whether or not move constructors should leave objects in a 'valid state', whatever you mean by that, is hotly contested. Personally I'm of the opinion the only valid operations on a moved-from object should be to move-assign to it (otherwise literally every mutating algorithm is broken) and, obviously, to destroy it.

> Often times leaving the original object in a valid state requires involves performing an operation that could potentially fail.

Which is exactly why I'm of the above opinion. Making move non-throwing is more or less always trivial and cheap, whereas doing so while ensuring a moved-from object has a valid and useful state, where all class invariants have been maintained, can be expensive.

You should definitely favour a noexcept move constructor that results in an unspecified state over a implementing a throwing move. Just don't do it. If your move constructor throws then doing anything useful with your class becomes very expensive (because classes like std::vector will start copying your objects to move them around).

> In the case of std::map and std::list, a conforming implementation may have to allocate memory in order for the original object to be in a valid state.

This is just wrong. Moving a std::list will not throw provided the associated memory allocator is noexcept move constructible (and std::allocator is). The same is true of std::map.
To elide a return copy/move, the compiler has to know at compile time exactly which local variable is going to be returned, so that it can arrange to have that local variable constructed directly into the return location, thus avoiding the need to copy/move it later.

So to elide a copy/move from an rvalue reference, the compiler would have to know at compile time that the rvalue reference always points to some particular local variable.

In theory a compiler could look into the inline definition of std::move() and determine that it always returns a reference to its parameter, but that's a rather involved optimization for the spec to require of all implementations.
I guess this then contributes to a feedback loop. People will check their stats, see that Firefox isn't used, and pay less attention. Sucky position to be in.

Look their own sales pitch in the article is the death knell for this startup.

Protocol with 911:

* Person has suspected heart attack symptoms.

* 911 is called, short triage on the phone.

* Ambulance is dispatched.

Protocol with this new startup:

* Person has suspected heart attack symptoms.

* Skype with doctor, short triage on Skype.

* Doctor quickly trains nurse (conveniently available on site) to take EKG (presumably while patient is grasping his chest).

* Nurse takes first EKG in her life.

* Doctor reads EKG, and calls 911.

Who in their right mind would call a gatekeeper instead of 911 in an emergency?
Yeah, you sacrifice consistency. Although some AirBnb units are MUCH nicer than even the fanciest hotels. You can get a complete kitchen, ground floor access, a yard, in-unit laundry, private parking, lots of stuff that can be super useful that are rare in hotels.

This is certainly unmaintainable. There are two aspects I find especially interesting.

The first is how many different ways sites are determining the browser corresponding to the user agent. You know that they're all based on "guess and test": come up with an idea for an if condition, open up the code in the 5 browsers you care about, see if the result works. It almost reminds me of the output from a fuzzer: it's a valid answer, but you can tell a random number generator and a lot of tries is what got you there.

The second is how many web developers seem fine writing the same website many times; once for mobile, once for IE, once for Chrome, once for Firefox. I've always taken the approach of doing exactly one site, and using whatever features are available in the worst browser the client wants supported. If extensive workarounds are needed to make the feature work in every browser, I say skip it. (I was always happy with what IE6 could do.) Of course, when I did web development, it was mostly boring corporate applications, not public websites that face pressure from competitors that are willing to write a codebase from scratch for every browser back to NSCA Mosaic. I consider myself very lucky.
That's true of some Airbnb hosts - it's their own home, and their letting it (or a room in it) out. But my experience of Airbnb is generally that the host has their own home elsewhere, and the Airbnb venue is a dedicated place to let. For example, someone who has moved in with their Significant Other, and is letting/sub-letting what used to be their own place.

Compared to a business hotel, it generally lacks in terms of concierge/information/predictability. But things like a full-size refrigerator, cooking facilities, and sofas can compensate (if that's what you're looking for).

Personally, when I travel on business, for a trip of a few days, I prefer a hotel. If it's longer, or if I expect to have to work from the rental site, I prefer an Airbnb.
"Lower your trip cost with amenities like WiFi, stocked kitchens, and free parking."

I'm LOL'ing! Airbnb is often several times more expensive than the opaque 3* hotel deals on Priceline! Whatever they do, lowering trip costs is not one of them!

Just to give you an example -- I was able to book several 3* hotels in Austin during SxSW for about $50 per night, all the while craigslist and such were at $200/ni for one person, or $300/ni for two. Heck, some guy was even renting out his trailer for 1.2k$/week, or something like that!
Great question - Call9 is different because we immediately put you in touch with an emergency doc, even as the first responders are trying to get to you. By the time EMTs get to the site, we have already begun triaging. And, when first responders do arrive, our physicians help make decisions based on their extensive medical expertise.

Right now, when EMTs get to the site, they don't know anything about the patient. With Call9, EMTs can begin work right away upon arrival.

As for long-term, we want this kind of service to reach everyone - that's certainly our end goal. But traditional emergency services have to completely alter their business and operational models to offer what Call9 offers.

> Also, dude, what part of being a PhD student at Stanford doesn't scream a tremendous amount of privilege?

Grad school is often fully paid for, particularly in STEM fields, because it's like indentured servitude. Undergrad at a fancy US school is much harder financially, but you can still go for free if you're on an elite scholarship and poor. So, go to a cheap undergrad / master's somewhere and then transfer to Stanford for the PhD, if that's what you want and are capable of doing.

Is one privileged to have the opportunity to attend grad school at Stanford? Yes, but that doesn't make it categorically unfair.

In the USA, magnetic swipe readers are EVERYwhere. And the collection of credit and debit networks connect every reader with almost every bank. It "just works" everywhere, and it's "impossible" for a retailer to be unable to connect to your bank.

-Chip-and-pin? The card reader probably can't read it.

-Apple/Google wallet and similar services? The card reader probably doesn't have an antenna for it. (Especially small retailers who can't afford the special card reader)

-NFC Visa/Mastercard? The card reader probably doesn't have an antenna for it.

-Paypal? Most retailers aren't set up for it. That's why Paypal issues magnetic cards in the USA.

-Paper checks? Most retailers don't want to lose money on the possibility of fraud. And most card readers can't auto-ACH a check.
I have been wondering about ways to allow communication in internet communities (games and other social spaces) that are safe (not allowing personally identifiable information) and cross-lingual. I'd love to see an online game attempt to adopt a symbolic language such as this. The lexicon is small enough that you might not even have to type - just select the word you want from a nested menu.
AirBnB can/could also be a benefit though - there are some original, inventive properties on there that few hotels can match.

But you're right - the trick will be matching those properties with professional management.
This confuses me. These aren't necessarily benefits to your service.

If the patient needs an ER visit, you are getting one, however it is initiated.

Community-outreach / in-call? Absolutely. I love that aspect of your service.

Your "A" and "B" benefits seem to be the same, not an either-or. The safer route in A comes from skipping the emergency room in B where applicable and appropriate.

I do like that you cut the waiting time to see an MD, regardless of the situation. Diagnosis is an important first step. But I'm curious about the 'medical kit' provided. Because diagnosis is limited to cases that don't require (for example) lab services, and for non-emergent cases, great. Prescribe the appropriate medication or treatment regime. For anything else, the outcome is likely to be the same - not much is changing in that "golden hour" (with all caveats thereto) in terms of definitive care.

I realize I may be coming across as cynical or skeptical in many of my comments, but I really do wish you success and would be very happy to talk with you further. I'm just raising some of the thoughts and questions that come to my mind as a first responder and, as I'm sure anyone will agree, anything that alleviates pressure on the 911 system is "A Good Thing(TM)".
It's not that we have trouble with it-- it really is pretty simple. It's that there can be a bunch of rules around it that make it not simple.

For example, how do you evalute postfix addition? If you have v1.0.0-alpha3 and v1.0.0-alpha10, are all semver implementations supposed to do an alphabetical check until it sees a string? Or should you zero-pad anything with text postfixes? And how do you deal with labeling branches or architectures?

Internally, we no longer use semver, we use the build number as the version, and the commit hash as the input to the deploy systems.
