I'm trying to build a programming language that might best be characterized as rust - ownership + GC + goroutines (coroutines with an automatic yield semantic). My rationale for starting this project was that I like specific features or facilities of many individual languages, but I dislike those languages for a host of other reasons. Furthermore, I dislike those languages enough that I don't want to use them to buil…

Neat! I spend a lot of time working with and on parsers and parser generators.

Did you use Sérgio Medeiros' algorithm for left recursion, perchance?

I'm tackling the issue of managing Reddit saves.

Across all platforms (not just Reddit), people including myself like to save/bookmark interesting content in the hopes of getting some use out of it later. The problem arises when you start accumulating too much content and forget to ever check that stuff out.

I'm working on a solution to help resurface Redditors' saved things using personalized newsletters. I'm calling it Unearth and users get to choose how frequently they want to receive their newsletter (daily, weekly, or monthly). The emails contain five of their saved comments or things and link directly to Reddit so that when viewing it, they can then decide whether or not to unsave it.

Basic functionality is all there, just needs some more styling and the landing page could be spruced up.

Dental treatments, besides being very expensive, are often (up to 28%) unnecessary. This happens because no-one keeps dentists in check. I am trying to make dental treatment and diagnosis reviews easy, cheap, reliable and fast.

I've been wanting to disrupt orthodontistry for quite a long time. With the state of 3d scanners, 3d printers, 3d software modeling, why hasn't the market price of orthodontist treatments dropped to cost-of-materials yet? As soon as at least one satisfactory / integrated open-source stack exists I think it's only a matter of time before it does...

It's already well underway:

Trying to figure out why learning how to cook is so tedious in a software world.

I'd like to know of a good book for the science of cooking. I hate blindly following recipes.

Like a poor man's version of this book by Microsoft CTO Nathan Myhrvold.

Alleviating homelessness using technology and data. I recently learned that homelessness is not just about the people you see on the street every day, but that homelessness is in fact a funnel that people fall deeper into as their situation becomes increasingly desperate. At the bottom of the funnel are the aforementioned group known as the "chronically homeless". The top of the funnel however, looks a lot different,…

This is great. As much hate as the topic of personal data gets here on HN, it has massive potential to solve alot of societal problems. Imagine a world of open data, but is utilized only for benefit. unfortunately, game theory skews the meaning of 'benefit'.

I am working on a solution for people to defeat procrastination. Here's how it works, you select a time slot for work, and we assign you an accountability assistant who will get on a call with you and keep in touch as often as necessary to keep you from procrastinating by holding you accountable for the task at hand.

I think the recent (BBC?) article about how procrastination was caused by a lack of emotional management, not time management made a lot of sense to me.
