Ask HN: What is something that doesn't exist that you would pay for?

A service that tells you something that doesn't exist that people will pay for.

* A personalized search engine.

* portable software that is in a usb that stores your medical records. The problem is that all medical records are disaggregated and you have to bring them everywhere with you and the systems are incompatable. However, if you made a portable system agnostic applicaation using something like electron and sqllite that allowed your doctor (or any doctor) to run it when diagnosing or taking patient history, then he gives it back when completed that would be awesome. Could export files for doctors records. even files woul dbe upgrade on their end, as currently I had to fax over my records but also show up and bring them in person because that was unreliable(possibly because it is half centrury old tech). probably hipaa compliant as you would be responsible(but in control) of your data. would payoff big in 5 years whne personalized medicine is a thing. can't do it on mobile because it would be too vulnerable, must interface with anything with USB.

Courses aimed at getting me into specialized job roles. E.g. a course aimed at getting a job as a Financial Trading .NET developer. It would probably be an amalgamation of courses on .NET that are used in finances plus courses that teach financial markets etc.

Similarly: professional certifications that mean something. I.e. a certification for .NET that shows I really know my stuff but just something I memorized like the MCP style exams (that's how I remember them being 10 years ago).

Bunch of .txt files and notepad++ would do the trick, no?

Udacity?
