Ask HN: What are you working on?

In the spirit of releasing things before they're ready...

I've been working on Violin.io (https://violin.io) since 2015. It's eventually intended to be interactive sheet music in the browser synced with YouTube recordings of classical music through the use of music information retrieval (MIR) algorithms. For example, click on the score at measure 50, and you'll get a YouTube video at measure 50, and you can change among different performances of that work at measure 50.

To view my rejected application for the inaugural Classical Goes Tech pitch competition last November, see https://stevetjoa.com/classicalgoestech/.

There remains technical challenges, so for now you won't find much yet other than well-tagged and categorized videos of classical works without sheet music. But I'm actively working on it.

You can help. If you frequently listen to or perform classical music, contact me at steve at violin io. I would like to know what specific works interest you. Currently, I'd prefer to focus on strings or piano, and Bach/Mozart/Beethoven/Brahms, and preferably chamber. But I'm open to all suggestions. (I think there's merit to pleasing a narrow audience very well, and with classical music variety being enormous, it can get out of hand quickly.)

A personal CRM of sorts. I want to use it to manage my family/social/colleague relationships.

Little things like noting spouses names and children's names, writing notes about encounters we have and something they mention that could be good to bring up next time, setting reminders - e.g. give X a call about Y, adding birthdays (and getting reminded ahead of time), preferred coffee/beverage. etc.

Currently as a web app but will also look to do a React Native app at some point.

As a side project I'm building a computer vision framework and hardware sensor for mobile robots. The target users are people who want to build applications for vision based autonomy, but don't want to go through the hassle of building the full 'stack' themselves.

The sensor is designed to be plug-and-play, so like the Kinect it just works out of the box.

The basic building blocks are in place now, and I'm currently working on C++ and Python APIs, and considering a Swift API.

I'm trying to make web service testing better with Assertible (https://assertible.com). Our motivations:

- For many small-medium sized organizations,developers manually test changes deployed to production and staging environments even if automated testing is already in place.

- Automated testing of a web service is much quicker and less error-prone then testing many workflows separately.

- Automating checks for security (coming soon), data validation (JSON, HTML), response times, and other assertions which are difficult for developers to test manually on every deployment.

- Scheduled health checks which let you know when the service is down (email, Slack, integrations)

Currently, we are focusing on automated post-deployment testing. Our primary goal is to connect into your current CI pipeline in a turn-key fashion; similar to how TravisCI and CircleCI work. We have support for GitHub deployments which can be used by services like Heroku, CircleCI, etc.

Here are some of the latest pictures of our GitHub status integrations coming soon: https://twitter.com/AssertibleApp/status/755115483209228288

I am working on a project that some of you might be interested in. Put simply we have built a database of beautiful underused spaces in major cities such as New York, San Francisco, and DC. (Over a hundred convenient spaces already) We are first launching a mindfulness & wellness brand that leverages these beautiful underused spaces a long with a few permanent studio spaces for mindfulness-linked yoga, meditation, and fitness offerings.

Particularly, the marketing of meditation as a commercial entity is largely stuck in the 1960's and we hope our brand with accessible and approachable offerings can shift this dynamic. The research backing meditation is enormous, but their still lacks many places where it can be done in ideal group settings with great instructors. Additionally, our platform of spaces significantly reduces overhead so great instructors with solid followings will truly be able to get paid significantly. It is our hope that this can create a virtuous cycle of attracting more quality meditation and mindfulness instructors into our society. Any thoughts on the specifics of building out a mvp of a map based app would be very much appreciated. Feel free to check out our very basic pre-launch site at 2b-infinite.com or to shoot me a line wat Connor@2b-infinite.com.

I am working on a social app for meeting people over coffee/tea. I am aiming to simplify the process of setting up initial meetings, whether it is to chat with a developer at a company you're applying to, seek advice from a seasoned entrepreneur, or just find someone to jam on synthesizers with.

The core concept is that you are incentivized into meeting people because as part of your profile other people will know what your favourite local coffee shop/bakery/cafe/whatever is and what you like from there so they will know what to buy you. You basically get to name your own price for a short conversation, or on the flip side, cheaply buy time from people whom you would otherwise not know where to find.

Haven't been writing any code I can't easily reuse for other ideas because I'm barely starting to validate the idea, but hopefully I can generate some interest in it as I think there are simple paths to monetization.

I am working on Comtify (https://comtify.com). We intend to kill email - seriously, no kidding!

Currently, Comtify behaves as an advanced collaboration tool. From a single page, you can do task management, knowledge sharing, file sharing, calendaring & scheduling, bug tracking in a highly intuitive manner.

What we are currently building is injecting the features of an email client into Comtify. This would mean that it would become the first collaboration tool which not only makes your intra-team work easy, but also inter-team communication (which currently happens over email).

This would also equip Comtify with a single-user utility - you won't have to invite your team to use it. So you can be a single person from a team using it, while other might not.

Your thoughts?

I just released my side project: JobRudder [1]. It's a career management app for the individual. It's got one click resume and performance review generation, career analytics etc.

[1]: https://jobrudder.com

I built it because i realized:

- Even if i work hard (i do) and smart (i try), a great career isn't just going to happen to me. I have to make it.

- Updating my resumes, writing performance reviews, all the career/hr tasks i dislike are necessary tools. My work speaks for itself but it needs help.

- I don't own my own career data, it's split up in all the employee engagement/hr compliance/goal setting systems i've used at all the companies i've worked for.

I'm working on a snail simulation side project.

TL;DR a web app that finds travel destinations according to your budget http://www.wanderapp.me

A project me and my GF have been hacking for the past few weeks for a problem we've had - we had money and available dates but didn't know where to go, so... we decided to build a web app that let's you enter your budget and available dates and you get places which fits that budget. we took a vacation shortly after the product was built ;)

An internal database of (potential) customers, searchable by non-tech sales people in order to generate lists to go after. Segmentation driven primarily by locale, and the company's location in the supply chain. Database includes company as well as employee information, enriched by something like clearbit, and other scraped sources. Side project.

Developing software to visualize and categorize street lamp bulbs and understand different kinds of light pollution at low cost.

(side project)

I've been working on making my deep NLP model Dracula work in the browser and on node.js. Here it is doing sentiment analysis: http://dracula.sentimentron.co.uk/sentiment-demo/

My side project is a web app to publish product updates (http://productmap.co). Right now, working on letting users leave feedback and suggest things they want to see in your product.

Small website to create GPS Heatmaps -

I built it to learn python and some sports api's for another project

I am building a Crypto exchange!!! :D
