       Ask HN: What are you working on?
        
       Hi HN, I'm curious to see what cool things everyone's building.
       What side projects are you developing? What are you applying to HN
       with?

       | Think highly general max patches that automatically export
       | realtime audio, midi, and automation data to a central hub, with
       | a GUI that allows you to assign that data to visual properties
       | that are then sent to a neat LED setup I've built. Akin to the
       | mod table in a synthesizer like serum/thor, but with all of
       | ableton's data on one side, and a light show on the other.
       | 
       | I started building this in react out of familiarity, and because
       | I really want the visual feedback, but this has introduced 100ms+
       | of round trip latency, which is enough to break the effect. It
       | has to go max -> JS runtime within max -> socket.io listener ->
       | react app -> listener -> arduino, which is goofy as hell. Trying
       | to figure out a lighter, faster stack for this without having to
       | learn both a new language and domain in tandem.
       | 
       | I'd love examples of projects in this space, if anyone has
       | favorites.
       | 
       | At work: A GUI/IDE/DSL for cross platform design system
       | management, to service one of the largest design systems in the
       | world.
       | 
       | We (Adobe) are about to start hiring an additional technologist
       | to work on this. Potentially relevant experience: typescript,
       | cross-platform UI dev, building version control systems, graph
       | DBs?, visual programming (scratch, nodebased, etc), anything
       | related to IDE dev or expansive config management tooling. That's
       | off the top of my head, don't take the list too seriously. My
       | email is psteele@, feel free to drop a line and I'll hang onto
       | your info, but won't promise anything beyond a "we'll see in a
       | bit". I'm not the hiring manager, just the primary IC.

       | 
       | Got the idea after starting piano lessons about 5 months ago.

       | getting the sound to come through (if you don't have a nice audio

       | zoom to just communicate verbally, works okay for fingering)

       | The keyboard I use to animate playback is a 3D model which

       | 
       | 1. Designing a protocol and air interface for an amateur radio
       | cellular network. This started out with some spread spectrum
       | experiments and an interest in low-probability-of-intercept
       | (below the noise floor) communication. The idea I have now is
       | sort of a cross between APRS and DMR using modern modulation
       | techniques. The network would consist of amateur rooftop "cells"
       | with internet connections, and mobile transponders that
       | communicate with those cells. There'd be some sort of callsign or
       | key based addressing scheme and IP-like network topology
       | discovery. Everything will be authenticated. I'd love to have an
       | encrypted mode, but unless the laws change, it probably isn't
       | going to happen.
       | 
       | 2. Open-source firmware or gateware implementation of a USB PD
       | controller that supports entering/exiting alternate modes
       | properly. Inspired by Kate Temkin's Luna project [1]. I got the
       | impression that PD was out of scope for LUNA, at least for the
       | time being, but it would be really nice to have both a USB and PD
       | stack that could be integrated onto a small, inexpensive chip
       | without the proprietary mess.

           | 
           | Compared to Borg, Snebu can handle dozens of servers going to

       | use a language other than Coffeescript to do it. So, we built a
       | bot that used C#... then we realized there was a lot of other
       | stuff that we had to do to run a bot, so we built a platform to
       | run it (and added support for Python and JavaScript while we were
       | at it).
       | 
       | We handle all the annoying stuff about running a bot (hosting,
       | persistence, secrets management, job scheduling) and add a bunch
       | of other cool stuff on top (Triggers, which make it so that Abbot
       | can respond to events from outside chat or on a schedule, a
       | package manager so people can easily share skills, the ability to
       | create some kinds of skills from inside chat, etc).
       | 
       | The timing of this Ask HN is perfect -- we've been running a beta
       | for Slack users for the past few weeks and just started beta for
       | Discord yesterday. We handle all the middleware so skills written
       | for Abbot work in both Slack and Discord without any changes.
       | 
       | Everything is free during beta, and we'll always have a free plan
       | for basic bot usage (we will probably tier based on the number of
       | custom skills people have running).
       | 
       | If you do end up trying it out, please let us know you found out
       | about Abbot from this thread -- just say `@abbot feedback I found
       | this from HN!` or `@abbot feedback I came from Hacker News` or
       | something similar. We're going to do something fun for our beta
       | testers (probably have some fun stickers made). We love feedback,
       | so even if you don't try it out; I'd love to hear why. My email
       | is in my profile!

       | An aggregator ala reddit/hackernews/twitter that uses a market
       | mechanism to better incentivise content discovery.
       | 
       | One of the biggest issues with existing aggregators is that:
       | 
       | - how well content performs is dependant on the attention it gets
       | immediately after posting.
       | 
       | - However, readers aren't incentivised to sift carefully through
       | new content, which is generally of lower quality than "frontpage"
       | content
       | 
       | - This means that how content performs is a lottery. Great
       | content is often missed just by chance
       | 
       | - This in turn means that there's no platform that encourages
       | unknown authors to create high-effort, thoughtful pieces. Instead
       | it's far more effective to blogspam.
       | 
       | I'm working on a platform that uses something similar to a
       | prediction/stock market to incentivise people to search for high-
       | quality content. Instead of upvoting, you effectively buy shares
       | in new content, which you can then sell at a later point for a
       | profit if the content proves popular. Equally you can buy
       | "downvote shares", which act like a short and help dampen rampant
       | speculation.
       | 
       | It's early days still, but I'm hoping this could be a great way
       | to encourage higher quality content creation.
