snapcard - Allows people to spend their bitcoins on any website at anytime, regardless of whether the merchant has it integrated. Like Amazon 1 click, except it works on every website and requires no merchant integration. Video Demo - https://vimeo.com/76122291 It's cool because - Spend bitcoins anywhere you want - No merchant integration - 1 click checkout so you don't flood a million websites with your personal dat…

Very cool!

Earlier quoted context omitted.

It's server-side. There's a record for each page/component in a database where the JSON is stored. It converts the "criteria" part into SQL, and the "options" part into HTML, and returns the resulting HTML for each component.

Might I suggest something like redis* for storing this data? Or is that what you mean by database? * http://redis.io/

Thanks for the suggestion. I've been meaning to try that out, maybe it's time to look into Redis.

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 HIPA…

You said that TrueVault will "handle HIPAA" and that "using TrueVault makes you HIPAA compliant."

I don't see how those claims are true. If the developer is a business associate, they're still required to have a risk analysis, policies, and training. If they're not a business associate, they don't need to be compliant.

So I guess I'm not seeing how TrueVault helps a developer avoid becoming a business associate. jph's case is marginal - if the covered entities all sign BAAs with TrueVault, maybe the developer can argue that they do not "create, receive, maintain, or transmit" PHI. Good luck arguing that with the covered entity, btw.

SilverAir - An athletic shirt that doesn't smell and designed to be worn at the gym and for everyday wear. demo@ http://www.yathletics.com It's cool because: It's made using pure silver which kills the odor-causing bacteria in your sweat, so you can -wear this shirt for your entire day and feel fresh, -reuse the shirt more often (i do). The fabric is completely new and something I made with my manufacturers from scra…

Well, I'm already sold on it, looks like a solid product; however my only questions now are: - How much? - International shipping? How much?

Thanks so much! The validation means a lot.

How much? $54 Retail, but when we open on kickstarter next week, we want this to reach as many people as possible and are going to give it out at (almost) cost:

1 shirt for $34.

2 shirts for $64.

3 shirts for $90.

US shipping included.

International shipping: Add $20.

Happy to answer any other questions you have.

"open-source", IP-free anticancer drug candidate ( http://indysci.org ) We're launching in January (or possibly December) It's cool, because we want to disrupt the way that pharma operates. Biotech could learn a lot from the way that the software industry has been revolutionized by the open-source philosophy. The world could stand to also see tangible benefits if we succeed in (re)proving it's actually possible. Peop…

Thank you and awesome! Although I've seen some great projects scrolling down, this is the first that has elicited a comment. I wish you all the best in your attempt to disrupt pharma -- it needs it.

I wrote a spectral analysis library called udsp:

http://www.eliteraspberries.com/doc/udsp-user-guide.html

https://code.google.com/p/udsp/

In the future it will include:

* support for more FFT libraries, like FFTW;

* some signals processing functions, such as basic frequency modulation/demodulation; and

* a NumPy-compatible Python interface.

Its best feature at the moment is convolution and correlation.

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 aware of this, unfortunately. This is a bug in Qt's Webkit. The font rendering on Mac OS changed in Mavericks, and it apparently does not work well with versions of Webkit prior to Mavericks release. I have to wait until this issue gets resolved. Here's the issue, if you want to take a look: https://bugreports.qt-project.org/browse/QTBUG-34332

Why not try and make a kickstarter campaign? - You have a working prototype. - You have a problem where there is a real need for a solution. - People on this thread are interested. Now you just need to interview a few people who cycle around, show off your gizmo and make it part of the video on your kickstarter page ;)

I've thought about Kickstarting a bit. I guess my hesitation is that I'm terrified of pulling the trigger to get something injection molded. I don't trust my 3D modeling abilities enough to know that when I get something injection molded it will work. And injection molding is a lot money, so if I mess it up, I might not have enough money for a redo. That scares me, a lot. I'm not sure, I guess I'm scared of actually…

Have you considered asking for help?

I'm willing to bet that there might be other hardware startups in your area, on HN or in your university that would be willing to give you a hand.

Thanks, glad you're digging it. Yes, I want to have a simple, powerful tagging interface for providing more context. Getting data out via JSON is easy, just have to build a secure API endpoint.

One other small piece of feedback. It would be cool if it automatically copied the link to your clipboard when clicking the button. Would save a whole step. :)

Great, thanks for the continued feedback :)

I'll add that to the list. It makes sense for desktop usage, whereas I'm curious how iOS & Android clipboard-ing works.
