Ask HN: What are you working on and why is it cool?

Bedtime Bulb (https://bedtimebulb.com/), a low-blue light bulb for healthy sleep. For every purchase, we give healthy lighting to one person in need.

For almost a decade, I've been working on the problem of reducing blue light at night, which could interrupt quality sleep. I started (and later sold) a company that automated Philips Hue lights to change color automatically, but realized that solution was too expensive and complicated for most people.

My latest attempt, Bedtime Bulb, is also the simplest. It's literally a light bulb that produces almost no blue. It's also the right light for the evening: much less eyestrain and a more comfortable feel than competitor's products.

I consider this an MVP but also the solution that's most appropriate for a general market.

I have been working on a project called Shareseer. Shareseer was born out of my pain of finding company filings as I was learning about valuation of companies.

Another frustration of mine was reading boilerplate text when I read the company risk section. So I applied some machine learning & Natural language processing to extract the unique risks. The way to access it is to visit https://shareseer.com then search for a company name or ticker. You will find the 10-k/10-q filings along with risks marked as important by our algorithms. Alternatively you can make a query to https://shareseer.com/search?q=NFLX and replace tick with your desired tick. Analyzed Risks are available for the S & P 500. Filings are available for all companies. The other features available are a real time insider transaction feed and a company filings feed:

It would be great if you could give the application a spin. I'm trying to learn:

a) Is this useful to you as an investor?

b) What are your pain points today in your research process?

c) Any other feedback you may have?

I think it’s cool because it allows any investor to improve their due diligence when buying an individual stock. It reduces the gap between what the people on Wall Street know and what the average joe investor knows. The insiders filings are an entire day faster than what major brokerages offer today. The risk analysis is unique too.

Doqume (http://doqume.com) It's a way to search text documents by specifying complex semantic conditions on items that have to be matched instead of simple keywords.

I think it's interesting because 1) it is challenging and it involves a lot of NLP (which I like) 2) I believe it's novel or at least I have not seen the same concept around.

Whether or not it is actually useful to somebody remains to be seen...

WarFlagger - http://warflagger.net/ Meant to do for messy, savage ideological discussions what StackExchange does for straight forward questions.

It is based on an open exchange format (RDF based, called OpinML) that allows you to publish your comments independently. It has annotation features and a vote system somewhat akin to that of Slashdot.

I’m working on validating Modular Neural nets with adaptive topology as an effective architecture for complex problems like disease diagnosis. I’m actually third on the www.pioneer.app leaderboard, with the username -_-

BankSpot - https://www.bankspot.org/ Provides search and discovery of banks and credit unions. Working on a review system and tools to remove barriers for the un-banked population.

For me it's cool because I'm learning more about hardware -- I studied maths, so not really focused on physical things. For the world, I think/hope it's cool because it's the first open implementation of the new FIDO2 standard, which means strong two-factor authentication protecting against phishing, and perhaps one day soon also strong first factor auth (the standard supports it, but I'm not aware of any major service that does).

Edit: grammar

I'm finishing a book about what makes products "premium." It's cool because a) many people don't know b) if they did, they could make more money per sale.

Wsid.com - http://54.88.93.252:8005/ A social experiment slash Q + A social networking site where ppl can ask the community What Should I do? It's cool we built a real-time polling feature for the answers.

currently working on a todo list app for iOS. None of the popular ones have any stats! No Progress bars or charts! Most just offer a simple linear graph that shows how many tasks finished in a day which doesn't really tell you anything. I find those apps to be slightly better (sometimes worse) than pen & paper equivalent. Infuriating when you want to plan out things and theres no simple UI to do that. I realize I can do most of these things in google sheets but sitting down and creating a template for sheets and maintaining it is a lot of work when you consider how bad the UX is going to be...
