Why It Takes More Than Experience to Build a Successful Health Tech Startup
Right now, innovations and the companies that create them are abounding in HIT. But that doesn’t mean that cracking the code to HIT success is all that easy. Even an experienced entrepreneur like John Kim says that healthcare is a difficult space for startups. And he should know. He started one.

In April 2010, Kim cofounded DoctorBase, a developer of a cloud-based communications platform that offers mobile engagements to patients for providers. The San Francisco, CA-based company seems to be steadily growing as its platform moves into small and mid-level health organizations. Kim said he knew that the idea for DoctorBase was a solid one, having had previous success with his startup Five9 and its development of virtual call center software.

Still, it hasn’t been all smooth sailing for DoctorBase. Kim admits encountering his fair share of snags in the healthcare space, which have since humbled him.

In this interview, talk about his successes and stumbles as an health tech entrepreneur, and how they are helping him shape the future of DoctorBase as its Cofounder and CEO. Read more at http://hitconsultant.net/2014/09/09/doctorbase-ceo-talks-health-tech-entrepreneur-hardships/

How to Integrate Testing in Development
Ask HN: What do you use to buy and sell stocks?
I signed up for sharebuilder a long time ago and it pretty much sucks. I've only been using it because of inertia while waiting for Robinhood to finally launch. My personal needs aren't huge, but I'm just sick of dealing with Sharebuilder.

What do you use and what do you like most about it?
>Why does adding English cost that much?

Localization in general adds a whole additional dimension of complexity. Every place you would normally just stick a word or phrase between quotes now suddenly has to pull that in from an array or database somewhere.
I'm pretty sure the merchant equipment is going to support either chip&signature or chip&pin, seeing as we already have signatures for credit card, and PINs for debit card transactions. The difference will be up to the card issuers. And I for one hate digital "esignatures" talk about all kinds of fraud waiting to happen with that bullcrap. I want to use either PIN or ink on paper signature. Make me use a screen to sign my name, and I'm signing it mickey mouse.
Adding english costs, depending on what your site is, roughly a half, to two employees, since, for one, the developers have to implement localization, which is not easy, and everything has to be translated. In most german companies i've worked at people were able to understand written english a little, but were unable to produce fluid english. So you have to hire translators. It might be easier in other countries.

> Americans will overlook grammatical errors.

I'm saying without proper translators you end up with engrish.

> Why is the Internet lacking in Germany? Is it because there are few German sites?

General lack of interest, and smaller set of offers.

Keep in mind that the east half of germany didn't even have a telephone net into most people's houses until 1989, when germany was reunified. As for the content: Just recently it was brought up that in the usa elder people increasingly turn to youtube. An example brought up was a wealth of wood-working videos. Trying to find german wood-working videos on youtube only gives you semi-commercial advertisements for big machines.
> The problem in the research community is that scientists have little incentive to duplicate earlier work just to check if it’s correct. Many journals have explicit policies forbidding the publication of work that attempts to replicate previous experiments.

This drive for unending novelty in the sciences is a shame on many levels. The good and useful work of duplicating and verifying results goes undone, and scientists are driven ever more forcefully towards designing studies only on the basis of what will attract grant agencies.

Duplicating major results carefully would be useful to the scientific record. Trying things that will probably fail, and then publishing negative results, would be useful too. But, for most researchers, doing this useful work appears to be career suicide.

No. Facebook is only vaguely usable without JavaScript (and actually has a banner telling you to turn JS on or use their mobile site), but most sites are not. For one of my projects we use Invision, Slack, and Trello for collaboration, and none of them work at all without JavaScript (though the latter two do at least prompt you to enable it). Google, in its primary function at least, does work perfectly without JS.

Periodically on here, and elsewhere, you hear people banging the "I browse the web with JS disabled and it's fine" drum, but I can only imagine that their use of the web is limited to a certain set of fairly static sites. RMS gets by just fine with web pages being emailed to him, but, you know, RMS isn't like most people.

I live in Buenos Aires (Palermo) and have bitcoins to sell for pesos. Please contact me if interested, and if you live in CABA.
Let me try to break this down.

This is a wrong transformation:

void writer(Tuple tuple) {
tuple.nonVolatileF = 5;
tuple.volatileF = 1;
}
void reader(Tuple tuple) {
int regNV = 0;
int cache = tuple.nonVolatileF;
int regV = tuple.volatileF;
if (regV == 1) { regNV = cache; }
// computation that uses both of the above
}

because `cache` might get assigned before `tuple.nonVolatileF` is set. (The same is true of regV, but I guess the untransformed program had that, so you don't bother). But you said that the JMM guarantees that all reads in C_i - C_(i-1) will see writes in C_(i-1); this means that C_3 which reads `tuple.nonVolatileF` will see the write to that variable in C_2, no? Since you're constructing an execution, why didn't you interleave the execution to make this trivially true? Also, can't you wrap the writer in an atomic block during transformation?
Ah ok. I've only ever used webmail, it makes sense SMTP would include the IP.
1) I don't think he faked it. I bet he thought it was real, but someone just used Satoshi's email when entering a fake order in 2013, the same way I occasionally use "bob@example.com" when creating a useless account.

2) Apparently real e-mails. He has re-forwarded some from 2011 to the original recipients, who have confirmed.

So possibly there's more of value in that account, but doubtful Satoshi's name/address. The hacker just saw the fake order and thought he got lucky.

VMs with a direct asm.js compilation mode (like SpiderMonkey) can compile directly to native code (in advance) with the vast majority of the JS attack surface disabled (including heap allocations, for asm.js v1)

In practice it's similar to the way NACL/pNACL can sandbox code due to the limited instruction set & validation guarantees.
No: Z3 proves the Hacker's Delight* trick almost instantly. The implementation above is not actually faster in practice, so it's rarely used; but its equivalence to popcount relies on Z/2^64Z properties that solvers do not seem familiar with.

Ask HN: I was offered a job while in college. Drop out?
I go to school near a major tech hub and have about two years left. I was offered a low six-figure job with significant equity (worth a few hundred k) with a 2-year vesting period. The reason the equity is so large is because I would be one of the few engineers in the team, and the startup has only succeeded in raising their seed funding.

Here's a list of pros and cons if I were to drop out:

Pros:

1) Financial independence.
2) Potential big pay off if start-up succeeds.

Cons:
1) I love my school.
2) My parents are against me dropping out.
3) No college degree.
4) I would be limited in choice for future employment (I think even though big companies are becoming increasingly accepting of college dropouts, there is still undoubtedly a sigma associated with them).

This is obviously a pretty big life decision, so while asking strangers may not be the best option, I am open to any input on this matter I can receive. Thank you HN community.
I agree. The email in the screenshot smells like a hoax (assuming your level stuff is legitimate; I haven't played with the source image in GIMP myself).

63101 is the downtown area (right by the Arch) – not really a place most people live, but the kind of place you might get if you Googled "St Louis zip code".

Also amusingly, "198 Bruce Ave" (not Street as in the email) is right in the center of the area Google labels Ferguson, MO.
"So it shouldn’t be surprising that venture capital firms are starting to worry that YC might start elbowing into the capital allocation part of the businesses."

It seems like YC currently doesn't have the whole Investor Relations infrastructure (or mindset of dealing with pensions) to get into the mainline VC business. I do think they are protecting their franchise against poor VC behavior though.

@dunmalg I guess that I find odd is that, at least for Java, i18n is really the design goal. Most web frameworks provided that ability. Wicket, Spring, etc. JSPs had tags that knew how to fish out content based on local. Android has is built in with English as the default, but with localization being additive. Heck, I'm doing that right now on my Android app.

As for Engrish, why is that bad on a first release. Yes, American's will laugh at it, but I doubt it will be enough to kill something that provide real value. Heck, Americans produce Engrish. That's never stopped us. If a German company tried to get ok English for their service/app/whatever version 1.0, they could take the money and improve for 1.4.
Wow, what a great job!

This is a really good looking web IRC client and it works so well with notification sounds, favicon updates etc.
Having multiple stages of the process is perfectly ok. The risk is offloaded to those who can bear it. Small teams of very young people can take home run like risks by bootstrapping. YC diversifies the Angel risk by giving lots of advice and structure to large groups of firms. The top VC firms provide growth capital, but even there it's not about sure things. Many investments lose money, but it's not as risky so they can have relatively fewer investments with much bigger bets. By the time it's a so-called sure thing, firms have done their IPO.

The Specialized video[1] is worth watching - it's pretty funny how astonished they were over how much power it saved.

If you are interested in this, then the book Faster: The Obsession, Science and Luck Behind the World's Fastest Cyclists by Michael Hutchinson is really good (and very well written).

He notes that human intuition about aerodynamics just isn't very good (you have to test) and that the current state of the art is no longer wind tunnel testing but computational fluid dynamics (CFD) followed by testing with a power meter on the road.

CFD lets designers iterate much quicker on designs and try things outside the norm (avoiding the local maxima problem). Power meters plus riding is better than wind tunnel testing because things like variable cross winds are very hard to test in wind tunnels.

I went through YC in '07. But prior to getting into YC, I got into Techstars' very first class. David was a total class act in letting me go through the YC interview process before making a decision and completely understanding when I decided to go with YC. Although I went with YC(and would do so again), that one experience left a positive impression in my mind of TS.

Probably not many people get into YC for the initial money these days. Its just access to that network and the alumni.

The annoying thing with CFD with analyzing viscous phenomena is the question of reproducibility. Flow structures in this regime (low Re, that is low speed and small length scales) are notoriously sensitive to surface defects, e.g. the hairs being analyzed. A CFD sim will show nearly the same results for a given problem, and current CFD lacks the fidelity to really model tiny turbulent features at these scales as well as the necessary fine surface definition. Experimental results may show drastically different results depending on the minute upstream flow variations, and surface quality: in this case, legs with hair/sweat/dust/oils could all trip the boundary layer to varying degrees. Stories abound of clumsy wind tunnel technicians who left skin grease on a wing model for a low-speed test and neglected to polish it with a rag...

As you seem familiar with the topic, can you give me a concrete example of when dependent types would be necessary or useful?

If we look at Haskell's Maybe or Swift's option type we have a clear case: There is no ambiguity between an unset variable and a variable set to a null or zero value, i.e., we can clearly express that something isn't there. That allows us to avoid magic numbers as a (horrible) workaround.

What do dependent types gain us?

[Edit]

Rather than clutter up the thread, I'll thank everyone here for the detailed responses below. Really, really interesting stuff.

> All of the functions above depend crucially upon the compile time invariant of having a fixed size list. They therefore work for any type-homogenous tuple, for instance, but we'd have to define the functions for each tuple independently. Using `Vect` we can classify the entire family of fixed-sized type-homogenous vectors all at once and dispatch functionality across the whole family.

That's pretty much exactly what I was looking for. Thanks again.
One thing they don't tell you in the Specialized video is that they're not testing someone who is pedaling. There's some much more turbulence from just moving your legs, that shaved or not shaved makes almost 0 difference. No one is coasting for 40 km. Even the time savings they do cite in perfect, almost platonic conditions is seconds over hours of riding.

Bicycling manufacturers always skew the numbers for how much savings (time, watts, whatever) their new top of the line frames will give you. It's all smoke and mirrors.

"Is it right ..?", well, it certainly is if someone applies for it. I don't see why this is a problem. $12 goes a long way in a lot of countries and this is being advertised as a remote job.

ah, that makes much more sense. If they had been pedaling I was wondering how they got rid of bias since it would be pretty hard to blind the rider as to whether their legs were shaved!
The last back-end system I built[1] had 3 failures in a year. First was a JVM misconfiguration (JVM neophytes) so we ran out of memory. Second was a temporary network outage that caused us to get behind our feed without the network bandwidth to catch up. Third was user interface code that wasn't tested.

Considering the system it replaced had more like 3 failures a day, the reliability was seen as "pretty good", so much that our relationship with ops was essentially we drop a jar, they tell us nothing happened.

TDD for the win. Not sure how/where a better type system would have helped.
