https://www.truevault.com/ TrueVault is a HIPAA compliant data backend for apps, devices, and sites. Developers use TrueVault so they can develop healthcare apps without building out their own HIPAA compliant infrastructure. You access data in TrueVault via our API and native clients. Think of TrueVault as Stripe for confidential patient data. You use Stripe to store credit card data so that you are PCI compliant. Ou…

What's a use case for this?

Another use case: apps/sites/devices that offer tools to help people track various health-related statistics.

Consumer-originated data, even though it is health data, is not protected health information (PHI) as covered by HIPAA. But, when that health data is shared with a Covered Entity (a doctor, hospital, insurance plan, or other HIPAA-defined CE) then it becomes PHI. And, the app handling the PHI needs to be HIPAA compliant.

People want information, not data. When an app takes health data and feeds it up to a doctor for diagnosis, analysis, advice, or treatment, then that data becomes PHI and your app needs to be HIPAA compliant.

Earlier quoted context omitted.

I was thinking about doing something similar. One of the things I wanted to incorporate was an reputation ability (beyond just blocking). It would be similar to a referral engine in Netflix or Amazon. So, I'm user A. I mark user B as a high-value poster. User B marks user C as a high-value poster. When I run across a post by user C, I see they have a good reputation. If many people I ranked as high-value, also ranked…

Are there any link voting sites on the public web that have tried this? I'd love it if YouTube comments worked like this. Why don't they?

I made a site a while ago that acts this way. Basically when a person vouches for another person or post it creates a metaphorical one-way electrical resistor from the person to the other person or post. Then it ranks posts by connecting you to one end of a battery and all posts to the other end of the battery and ranking posts by how much current flows through them. It is at thoughtocean.com. Pretty dead now though.

I'm building a distributed network, called Aether, that allows people to create and participate in reddit-like forums anonymously. It's fully encrypted. Take a look at http://www.getaether.net It's cool because: * It's anonymous. The posts jump from one node to another with no author information except a nickname. They cannot be traced back to the origin. * It's encrypted with TLS_RSA_WITH_AES_256_CBC_SHA cipher suit…

Unfortunately, it does not work on Mavericks. The screens are totally messed up, past 3rd steps, you cannot read anything in the forms.

I'm working on a POSIX-ish OS in Brainfuck. I'm working on it because brainfuck is awesome and writing a kernel in it is even moar awesome. I'm currently trying to figure out how to port several basic GNU coreutils to the system. The kernel boots and hangs in QEMU. That's good for now; at least it boots. Now, the important thing is actually getting it to run bash, and a few basic coreutils, specifically cat, mkdir, e…

What compiler are you using? and will this be open source?

I wrote my own in C++. It's intermediary, so it first translates BF code to C and then uses gcc to compile the intermediary C code.

I'm working on getting it to compile straight to assembly. Yeah, yeah, I could have used https://github.com/ahorn/bf-compiler/blob/master/bfc.c, but eh, what the hell. It's supposed to be a hobby project.

I'm working on https://github.com/Granary/granary . It is a Linux kernel dynamic binary translation framework. It's cool because it lets you rewrite the Linux kernel (at different granularities) while it's running. This is useful for analysis, debugging, etc. Right now I'm putting together benchmarks for an upcoming paper deadline.

made an account after years of lurking, to say how awesome this is.

Thanks, that's really flattering! I would love to hear about potential use cases that people might have for this.

A high performance, affordable personal airplane: http://www.skycraftairplanes.com It's extremely fuel efficient, can fly 575 miles on a tank, cruises at 118 mph, and comes standard with really nice instrumentation including GPS, collision avoidance, synthetic flight, and an auxiliary input for your iPod. They sell for $55k. Here's the HN post I made a few months ago: https://news.ycombinator.com/item?id=5826062

Very cool! I can't believe how cheap that is. And being able to store it in a trailer is a big deal.

Also - you have a solid, usable website, but I think it could use a little visual improvement. If y'all are ever considering a redesign, give me a shout. I build WordPress sites in my spare time and work with a couple of good, affordable designers.
