Launch HN: Medumo (YC W18) prepares patients for surgeries
Hi HN! We are building enterprise software that prepares patients for surgeries (http://www.medumo.com). Millions of patients go through these things every year. The problem is that patient instructions are provided months in advance, in the form of paper handouts or verbal instructions that are easily forgotten. As physicians, we saw firsthand how poor patient experience can impact hospital operations and surgical outcome. For example, when patients forget to stop medications that can cause bleeding, the surgeries have to be cancelled last minute which is costly. Or worse, poorly prepared patients get the surgery and have avoidable complications.

Our team came together to solve this problem with patient navigation software that gives turn-by-turn instructions, reminders, and educational material through friendly, accessible medium (SMS/email) to deliver the best experience and surgical outcome.

Unfortunately, health systems are notorious for moving slowly, so introducing a new digital platform can be challenging and slow. We are overcoming this by starting with simple use cases like colonoscopy, proving our value quickly and expanding to other areas. Another challenge is that patients respond differently to instructions; so instead of taking a one-size-fits-all approach, we are constantly varying instructions and A/B testing patient behavior to improve outcomes.

12 hospitals use our software to date. We have demonstrated improvement in show rate and procedure preparation quality. Here’s an example: https://bwhbulletin.org/2018/02/01/endoscopy-center-sees-suc...

We know HN has a lot of people who have experience building or selling software to hospitals and faced tough obstacles with the scars to prove it. We'd love to hear your thoughts around hospital enterprise sales, pilot design, patient engagement, and anything else that you've seen come up on your journey!

Thrust isn't that much of an issue. Yes, Falcon 9 cannot hover. But they don't want it to anyway, as it's too wasteful on fuel.
> These systems are primarily for fighting nations not named Russia and China.

But are those "nations not named Russia and China" realistically going to be able to do anything to a destroyer like this? Could they have realistically done anything to the previous generation of destroyers? It seems (to my uninformed eye) that these upgraded destroyers are almost comical in how far ahead of the technology that any adversary has (once again, those not named China and Russia).
Was it inevitable that the Equifax situation became partisan?

I'm a market constructivist, and I'd prefer the simplest possible solution which regulates Equifax and its immense externalities out of existence.

But isn't there also a libertarian case to be made that the credit authorities are a cartel and should be deregulated out of existence? And if that's the case, can't at least some of us find common ground?
Very similar experience, and what I was thinking about as I read this article. The signs it says to look out for are essentially standard flu symptoms crossing a poorly-defined subjective line of severity.

We had extreme lethargy and high fever for a couple days, and our threshold was crossed when the vomiting started. The boy walked into the ER with us, collapsed during chest x-rays, and was diagnosed with pneumonia a few minutes later.

Having had the pleasure of dealing with a (different) child experiencing febrile seizures, I'm not sure I'd want to wait for seizing before getting a diagnosis and supportive care. Seizure protocol involved multiple LPs.

I'd love better criteria than "extreme discomfort" and "clammy skin". Persistent high fever is one (but apparently flu can take a turn within 48 hours, so that's out the window). Relapsing fever is a good one. What else are the clear signs?

"...eco-friendly alternative to using plastics and metals..."

Would someone be able to explain to me why metal isn't "eco-friendly"? I understand that some plastics degrade into small, unfriendly particles over time (and others can't be recycled), but I always thought that metals were fairly easy to recycle with a very high recovery rate.

Seems like acoustic tiles would not be an impossible technology if you're already lining the other side with radar absorbent materials.

Stainless Steel is a huge class of metals, most (but not all) have nickel in them. Also alloys of cupronickel, coin metal, cobalt chromium, and nitinol all have nickel in them. And certain countries lie constantly about nickel content in metal they sell. When we source for medical implants, we have to specify no material from certain countries, because we can't trust their certifications, and we can't re-do all of the certification testing on our own.

Nickel is just too useful (and pre-existing in a lot of metal ores, I think) to stop using it, despite the fact that a large percentage of people are allergic to it.
I've seen folks with readers on Chrome on Linux. I don't mean to imply that Electron magically providers full accessibility; just that the underlying engine has much more robust support not only for readers and navigators (to which there is a ceiling folks aspire to), but also for auditing.

It's not really possible for developers to understand the full extend of accessibility needs unless they experience it themselves. As such, Electron and Chrome's accessibility auditing tools that capture these needs are an incredible step forwards.

As for Narrator, I think historically folks have been somewhat inclined to use third party or direct integration tools because it was widely considered to be inferior to the capabilities provided by direct integrations like ChromeVox or Apple's (superior) Voice Over (which from all reports I get and can find casually searching, works as well as Safari if not better).
A large portion of the efficiency of small engines comes from the reduction of "hoop stress". This is the linear tension in the wall of a pressure vessel(rocket engine) which varies as the square of the diameter. Twice the diameter = 4 times the pressure (hoop stress) the walls must take.
A rocket is a special case of a balloon - with an expansion nozzle attached to couple the impedance of the combustion chamber to the outside environment.
This means that 9 smaller rocket engines will weigh less than 1 large rocket engine of the same thrust. On top of this is the small engine basic throttling capability with the overlay of cutting out engines to add greater capability.
Here I am thinking that they would really expand on the points but no, it's just a list.

I've lived and worked in Colorado my whole life, joined Google Boulder about 8 months ago. Spent a ton of time in Boulder before that; my wife is from Boulder proper. Honestly? Google is barely a speck in the whirlwind of changes that Boulder is undergoing. Tech is a huge part of it, but you can't throw that entirely at Google's feet. There's been Silicon Valley expats and tons of other folks moving to Boulder for years.

Back on Google for a moment:

Lets talk neighborhood. The older Google buildings are renovated, small buildings. One of them was a Circuit City that closed. That should already give you a good idea of the area. It isn't trendy downtown, just primarily commercial space.

The new Google building is larger, about 3 blocks away, and located in what was a basically condemned. There's empty, undeveloped lots across from it on one side, and a huge sprawling Whole Foods with a massive parking lot on the other side. Google's new building is flanked by a large Target. Overall, the building is not actually that large. It's 4 floors and built as two halves joined in the center with a bridge.

It isn't the trendy part of town. It's developed a nice building in an otherwise lower-traffic area. I know there's follow-on effects from employing new folks in the area (housing, traffic, etc.), but I don't see how that's overall different from the general influx of folks into Boulder.

Perhaps it's myopic of me, but I don't see "us" (as if us vs. them is a productive use of time) being a negative force. Google Boulder employs lots of folks, and the vast majority of them have lived in Colorado for more than the last few years.

I'd like to know what we're doing to destroy communities and how we can prevent that.
Yeah, I'm not buying that there are thousands of k8s "Seniors" out there, and they just aren't the people that are being hired. I've been in operations for 20 years, and I think I would qualify for what you would call "good devops" in that I am a generalist with a wide breadth of experience in systems as well as programming. Kubernetes is a beast. We run it from scratch, in production, and just keeping up with the changes since the project inception can be maddening.

I did much of the early research POCs for my company when the idea of containerization really took off, and my deployments would seem to not have a shelf life of more than a few days before I would have to conform to some new method they came up with. I was using Tectonic when it was first released and the documentation would change underneath me as I would try to set up the clusters. It's a LOT to keep up with.

I can understand and explain to someone every protocol or idea underlying Kubernetes, sure, because they build upon standards that we have all used before in operations. But to try to understand how it is all working together within Kubernetes, and then add in the complex interplay if you are like us and integrate with non-k8s systems that have comlex firewall and routing rules now to allow the intercommunication... add in Calico or Flannel...Docker under the sheets with all its warts...it's a lot to manage. You need people that are engaged with the k8s project at a level that would normally be reserved for Googlers working on it.

Don't get me wrong... I like Kubernetes for the most part. I do agree that if you are planning to run in-house, you are in for some challenges, and that you will need a very high caliber of operations team to deploy and maintain it.
It's the second-biggest in the city's history after the GM building in 2008, which went for 2.8 billion (https://nypost.com/2018/02/06/the-history-behind-googles-mas...). The current record for a single transaction is the Stuy Town purchase in 2015 for 5.4 billion (https://www.nytimes.com/2015/12/19/nyregion/dollar5-45-billi...), but that was more than one building.

Also from a numbers standpoint. They keep buying fewer and fewer airframes as costs rise, which I'd assume means they'd be very vulnerable to attrition against a peer adversary. High-tech planes aren't very helpful if you have none left or too few to risk.
Yeah, I agree with you. It's very Eternal Septemberish. Many of the political discussions about the flaws of democracy are probably relevant here, too.

Zakaria has some similar arguments:

https://en.wikipedia.org/wiki/The_Future_of_Freedom

This is then applied to America to argue that the increased democratization of American society and culture is what has caused the perceived failures of the government and governing elites.

We have a tendency to see size and democracy as obvious goods, but there are certainly some limits there. It's funny how around the time Digg got going, all the talk was about the "wisdom of the crowds". Not sure anyone wants to make that argument today after 15 years of social media.
That's easy, if you're single. But "renting just a room" isn't really an option for couples, or families.

That said, if you're moving to the Bay Area for a job, you need to take into account that six figures here is not the same as six figures anywhere else.

I am getting a bit annoyed by holier than thou coding evangelists.

Writing good code is hard,

writing good tests is hard,

writing good docs is hard,

and even harder is writing code to do the right thing.

If someone has lots of exploratory code, trying out different approaches to a problem, maybe producing some performance comparisons, maybe exploring that weird API the other part of the company is offering, these are all valid reasons to not follow a prescriptive methodology.

Yes, having short iterations with working software as a deliverable is great.

Having close contact with your user base for fast feedback is great.

Having continuous integration so that at almost any point we can see genuinely where we are is great.

But honestly, after those three, which I think compare to "use memory managed languages" in the list of genuinely useful software engineering innovations (and let's face it, none of them are software but process, and they are all arguably the same thing - fast feedback loops) I struggle with the religious zeal for pair programming or other "must haves".

it's not they aren't sensible practises, but with a gun to your head, you need to carefully choose what to throw away.

Trying to simplify my argument:

There are no silver bullets left in the software pistol. we can make our code as sweet as we like but the value will come from building the right thing, not building the wrong thing in the right way.
It’s entirely predicated on luck, but rephrase luck as “opportunity” and see you then need to also have the skills and perseverence to capitalise on that opportunity. Of course, the problem is there is having the luck to be born into a situation where you could develop those skills and attitude, either through genetics or an encouraging family environment.

To me #5 is talking about the myth that surrounds premature optimization. That is - this idea that thinking through data patterns (or other basic aspects of code) early on is a waste of time. It's usually not.

Making the choice to work with collections that can be accessed in O(log n) rather than O(n^2) is a trivial optimization.

Maybe you don't need to scope out every subroutine, but taking the time to review the basic performance features is something we can all strive to do.

This advice can work out really well, or really poorly.

I live in one of the largest cities in North America, and despite nearly three decades of house prices rising every year, a quarter of the houses in the city are still worth less than they were in 1989. What I pay in rent for my place would only cover about 60% of the mortgage. The only way for your plan to work out would be for housing prices to continue to skyrocket for many years. And they might.

Instead, I took the downpayment for a house, plus the 40% I save every month from not having a mortgage and put it in index funds. Things will have to go really well in the housing market and really poorly in the equity and debt markets for me not to come out ahead.
This is such a fascinating cycle.

Large pensions & sovereign wealth funds are so desperate for yield vs. low treasuries that they have pushed income producing commercial real estate values to all time highs.

As a result these fund managers are then forced to take on larger risks to cover their liabilities by making larger portfolio allocations into public techs like Google, and privates like AirBNB & Uber.

And this dry powder has helped the technology companies get so insanely big and sophisticated that they are hiring away the best fund guys to manage their own treasury desks and drive commercial real estate transactions like this one!

Funds would have KILLED to get a deal with Google locked into a long term lease.

But because Google is taking themselves off the market as a tenant, the funds again have to go and chase riskier yield, like larger allocations in tech . . . the entire macroeconomy is just turning into a bizarre Möbius strip . . .

I wouldn't be so negative. The money coming in allowed newbie engineers to get into the field and existing ones to get smarter and increase their skills. Not having such a project would lead to a vacuum in the knowledge required to do those sorts of projects (I don't believe the US has any other project of this sort underway). I'm sure they'll be able to learn from what went wrong to make the next project turn out better.

One goal of BFR is Mars, from which you can only get back if you can produce fuel on the ground. Which kinda rules out RP-1 as propellant. Hence the need for a methane engine.

Unrelated to the number of engines here, obviously; just another point to consider. And if they end up designing a new engine they could just as well apply what they have learned in the meantime. Merlin is a very conservative design, favouring simplicity and cost over thrust. If you plan for re-using your rocket a thousand times, cost of an engine isn't that much of an issue anymore and you can prioritise other aspects.

The difference between aerospace and computing is that aerospace is heavily materials dependent. Getting a bad pixel in a monitor is rare but when it happens it’s not catastrophic. When you’re producing a ton of parts you have to also maintain quality. Not doing so will introduce impurities which will alter the material properties. An alloy with different material properties could potentially burn, fracture, expand etc more differently than represented in their acceptable failure models.
