Ask HN: What is your current side-project?

Hi all, Been experimenting a lot with Mobile development recently and yet to start on something. Just wanted to see what you guys are building so I can keep myself in the loop

zb1plus 6y ago
I have two side projects. The first is a PDF reader that persists reading state between devices and has a queryable notes overlay. For this project I am using SwiftUI and targeting iPhones and desktop MacOS. The second centers around exploring how to conduct interactive virtual lessons in VR using Mozilla hubs.
- app17 6y ago
  Is your PDF reader open sourced? It's a feature I'd like to implement at some point in my own personal project (https://github.com/appaquet/exomind https://github.com/appaquet/exomind)

My main project is a self-hosted analytics platform: https://www.usertrack.net https://www.usertrack.net I am still struggling to accomplish my goal of becoming sustainable by focusing on the self-hosted part instead of the SaaS part, but I'm not giving up. I do think that self-hosting is the future! :)
- enonevets 6y ago
  Honest curiosity here. With so many competitors in the space both free and paid, and with many doing self-hosted, privacy conscious angle, and many open source as well, what are you doing to separate your tracking from those. At a glance, I wasn't able to discern the major difference and I'd imagine a lot of users looking for analytic solutions might fall into the same thoughts.
  - XCSme 6y ago
    Thanks for the feedback! I think most of the unique points are mentioned on the landing page in the "What's different about userTrack?" section. The main gist is that userTrack is primary self-hosted, so the product's goal is aligned with the customer's goal. A platform like Matomo for example, earns money by providing a cloud solution, which means that anyone who chooses to self-host instead of using their service will reduce their revenue. This also leads to them making it harder to install and maintain the self-hosted version and they also provide some features only for the cloud plan (session recordings, heatmaps). Most of the other open-source analytics platforms that you might be referring to are pretty simple and usually only provide basic visitor stats. tl;dr: ease of installation, automatic updates, human support, highly performant/well optimized, unique interface and features, very affordable compared to alternatives with similar features, bootstrapped. Apart from this I am also trying to promote self-hosting as much as possible, thus I am continuously looking for and promoting different ways to reduce 3rd party dependencies and making it easier to do so.

My main side project is: https://minecraft-playdates.com https://minecraft-playdates.com Minecraft server hosting for parents. This is a fully fleshed out and working service with paying customers. My secondary project is https://golang-labs.com https://golang-labs.com. With this one, I'm exploring whether there is a need for an enterprise focused module proxy for Golang. The issues I see with the public proxy are: build repeatability, license compatibility, and information security. Please reach out if this is something you care about.

I have been working on Exomind (https://github.com/appaquet/exomind https://github.com/appaquet/exomind), a personal knowledge management tool that takes the form of a unified inbox in which you can have your emails, tasks, notes and bookmarks organized into collections. I have an iOS and a web/electron client at the moment, and a simple Chrome extension for bookmarking. Its backend, Exocore (https://github.com/appaquet/exocore https://github.com/appaquet/exocore), is built on top of a personal / private blockchain and is made from the ground up to be hosted in a semi-decentralized fashion on your own personal devices (your computer, raspberry pi, a cloud instance, etc.). It is written in Rust and has iOS, C and Web (WASM) clients. It has very rough edges, but I'm using it daily to organize my life. It has also been my learning playground to improve my Rust skills over the last two years. If all goes well, I'm a few months away from some kind of tech preview.

Mine is a service to take payments inside browser extensions without needing to run your own server backend! https://extensionpay.com https://extensionpay.com :D I made it so I could use it in my own extensions. Definitely lowers the barrier to making profitable side-project extensions. Open-source library is here: https://github.com/glench/ExtPay https://github.com/glench/ExtPay
- obviouspenguin 6y ago
  5% on top of the Stripe fee? That seems extremely high - do you actually have customers willing to pay that?
  - Glench 6y ago
    Yep! My customers so far have been really happy. :) To compare to other services: the Chrome Web Store fee was 5%, Gumroad's fee is 5% + the Stripe fee, and my main competitor is charging 6.5% + stripe fee. Pretty standard. Why do you feel it's extremely high? And if you think about the value of ExtensionPay... it saves people at least $5 / month on server costs, plus the time/ energy/hassle of creating their own payment system (which involves creating a user management, integrating it securely with the extension itself, figuring out how to integrate with a payment processor, setting up a database, sending emails, managing a server etc etc). Plus a lot of my customers are indie developers with limited resources that just want to focus on their extension.

I've been writing fiction. For years my side projects were all programming related, and that was awesome, but last summer I decided to try something different and get into creative writing again. I used to love it as a child and haven't done it in years. It is nice to do something that is quite different from my day job, and brings in a bit of a satisfying side income as well (not that it'll be paying my rent any time soon).

Building a tool to make use of un-used domain names. https://www.newsy.co https://www.newsy.co I had about ~30 domain names which were not doing anything. I got tired of them. But I didn't want to spend time working on them. So I built Newsy, which converts your domain name into a fully functional & automated content site. It finds niche contents and display them like Reddit. Over the months, I've built membership, newsletters, comments, social sharing, widgets, RSS, API and even sending email using your domain name via GMail. Finally, I've started to letting these domain names to monetize via adding your own ads. Got any un-used domain names? Would love to hear your feedback!

My girlfriend and I really enjoy good food and travel. We spend a lot of our time cooking, eating, and going to breweries and wineries. We have a few favorite cities near us, like Charlottesville and the surrounding wine country in Virginia, and Portland, Maine. We've been there with enough frequency that we've developed a sort of reputation as the go-to experts for those areas, and have sent a long e-mail itinerary and travel guide to our close friends probably 10 or 15 times for each place. Sometimes our friend doesn't drink alcohol, so we go through and scrub all the breweries and wineries. Sometimes they're gluten free, so all of the pizza and bagels we love get cut. After doing this several times, we realized it would be cool to have an app to do this. So that is my side project! It will be part Canva, part Facebook Recommendations, maybe part knowledge-base? Filterable lists, creation of itineraries, notes about each Place. Export to a static site with a link you can share. It is already integrated with Google Maps and Places APIs, so it's pretty easy to get up and running. The neat thing is, as I mentioned above, it has filters. So you can tag places with "winery" or "vegetarian" or something, and when you're crafting your collection of places for your friends, you can filter on those tags really easily. You could just click the "winery" tag to instantly create a "Virginia Wine Guide". I'm not totally sure it has broad appeal, but I'm hoping a few travel bloggers might get some use out of it. V3 will probably have some sort of "export to CMS" feature.

I've been (slowly) doing Advent of Code 2019 on an STM32F303 microcontroller. I want all of the problem data to be stored in the binary, with the answers being output on a display. Most of my time so far has been spent on getting the clock working, and compression/decompression. I only have limited space (256KB), and the 20 of last year's problems I solved take up 221KB, so I decided the best course of action would be to store them compressed when possible. I did consider just using compression library, but decided against it partly because it would be more interesting to write it myself, but also having a quick look I couldn't find one that could do decompression without needing additional temporary storage. It's not that fancy, just LZW with a multi-stage compression to optimize the dictionary. Because of how many of the inputs work, you can often handle it in smaller chunks (e.g. one line at a time, I called them records), so the inputs have a small amount of pre-processing on my PC to split them up into smaller chunks so the entire input doesn't need to be held in RAM at once. Of course, not all input data will compress well, some will even "compress" to a larger size, so I've also abstracted over the data storage so that it can handle reading records from compressed or uncompressed inputs. I've done 4 days so far, and none of the inputs have compressed. Total runtime is 3.24 seconds (that day 4...). Current state can be found here for the morbidly curious: https://github.com/Measter/AdventOfCode2019 https://github.com/Measter/AdventOfCode2019 Spoilers are in the mcu/src/challenges folder.

Cool to read about all the various things people are doing. I'm building a virtual tabletop for tabletop roleplayers that play narrative driven games and theater of the mind style games. I'm using text parsing to accomplish different tools for storytelling and improvisation. Believe that is the quickest way for a GM to produce content and rig their games. The tech stack is Svelte and Sapper with MDSVEX and Pouch/CouchDb/Websockets. The database part has been the hardest so far and haven't gotten that far. Got some decent character sheets out there but just using local storage for now. Got working slide decks, rollable tables and interactive fiction in dev but knitting it all together is a big job.

Been working on a service to let you listen to the web -- similar in function to the audio part of the Pocket app. Mostly using AWS Lambda and SNS. Some occasional weirdness in stringing functions together -- might do more with Step Functions. But weird part is some calls just seem to hang and never return -- unless they get a clean/new function of their own. Using Pythom 3.8 with Boto3 library. But generally amazed with what Lambda seems like it might be able to do if I can get it humming. http://readonthegoapp.com/ http://readonthegoapp.com/
- carmen_sandiego 6y ago
  Step functions are interesting in theory but they become quite messy in my experience. Are you using Chalice for your Lambda functions? Or something else? What kind of problems are you having with SNS? With Chalice it should be pretty easy to just trigger on SNS messages that come after each step, though I’m not sure which steps you would need for your app. Is it TTS with Poly running async or something?

https://cleave.app https://cleave.app Cleave is an application that lets users persist OS state as a "context" - saving and loading open applications, their windows (and their positions), tabs, open files/documents and so on. Think of it as a workspace or project manager from an IDE, but on the OS-level. Started because of frequent multitasking of heavy work with limited resources. Made it because I wanted to switch between studying, working, reading, looking for an apartment, etc. without manually managing all states or consuming all resources. I'll release an Open Beta (macOS) as soon as I finish license verification and delta updates, but I keep getting sidetracked...

With so many competitors in the space both free and paid, and with many doing self-hosted, privacy conscious angle, and many open source as well, what are you doing to separate your tracking from those. At a glance, I wasn't able to discern the major difference and I'd imagine a lot of users looking for analytic solutions might fall into the same thoughts.
- XCSme 6y ago
  Thanks for the feedback! I think most of the unique points are mentioned on the landing page in the "What's different about userTrack?" section. The main gist is that userTrack is primary self-hosted, so the product's goal is aligned with the customer's goal. A platform like Matomo for example, earns money by providing a cloud solution, which means that anyone who chooses to self-host instead of using their service will reduce their revenue. This also leads to them making it harder to install and maintain the self-hosted version and they also provide some features only for the cloud plan (session recordings, heatmaps). Most of the other open-source analytics platforms that you might be referring to are pretty simple and usually only provide basic visitor stats. tl;dr: ease of installation, automatic updates, human support, highly performant/well optimized, unique interface and features, very affordable compared to alternatives with similar features, bootstrapped. Apart from this I am also trying to promote self-hosting as much as possible, thus I am continuously looking for and promoting different ways to reduce 3rd party dependencies and making it easier to do so.

My secondary project is https://golang-labs.com https://golang-labs.com. With this one, I'm exploring whether there is a need for an enterprise focused module proxy for Golang. The issues I see with the public proxy are: build repeatability, license compatibility, and information security. Please reach out if this is something you care about.

I have been working on Exomind (https://github.com/appaquet/exomind https://github.com/appaquet/exomind), a personal knowledge management tool that takes the form of a unified inbox in which you can have your emails, tasks, notes and bookmarks organized into collections. I have an iOS and a web/electron client at the moment, and a simple Chrome extension for bookmarking. Its backend, Exocore (https://github.com/appaquet/exocore https://github.com/appaquet/exocore), is built on top of a personal / private blockchain and is made from the ground up to be hosted in a semi-decentralized fashion on your own personal devices (your computer, raspberry pi, a cloud instance, etc.). It is written in Rust and has iOS, C and Web (WASM) clients. It has very rough edges, but I'm using it daily to organize my life. It has also been my learning playground to improve my Rust skills over the last two years. If all goes well, I'm a few months away from some kind of tech preview.

Mine is a service to take payments inside browser extensions without needing to run your own server backend! https://extensionpay.com https://extensionpay.com :D I made it so I could use it in my own extensions. Definitely lowers the barrier to making profitable side-project extensions. Open-source library is here: https://github.com/glench/ExtPay https://github.com/glench/ExtPay

obviouspenguin 6y ago
5% on top of the Stripe fee? That seems extremely high - do you actually have customers willing to pay that?
- Glench 6y ago
  Yep! My customers so far have been really happy. :) To compare to other services: the Chrome Web Store fee was 5%, Gumroad's fee is 5% + the Stripe fee, and my main competitor is charging 6.5% + stripe fee. Pretty standard. Why do you feel it's extremely high? And if you think about the value of ExtensionPay... it saves people at least $5 / month on server costs, plus the time/ energy/hassle of creating their own payment system (which involves creating a user management, integrating it securely with the extension itself, figuring out how to integrate with a payment processor, setting up a database, sending emails, managing a server etc etc). Plus a lot of my customers are indie developers with limited resources that just want to focus on their extension.

I used to love it as a child and haven't done it in years.

Building a tool to make use of un-used domain names. https://www.newsy.co https://www.newsy.co I had about ~30 domain names which were not doing anything. I got tired of them. But I didn't want to spend time working on them. So I built Newsy, which converts your domain name into a fully functional & automated content site. It finds niche contents and display them like Reddit. Over the months, I've built membership, newsletters, comments, social sharing, widgets, RSS, API and even sending email using your domain name via GMail. Finally, I've started to letting these domain names to monetize via adding your own ads. Got any un-used domain names? Would love to hear your feedback!

My girlfriend and I really enjoy good food and travel. We spend a lot of our time cooking, eating, and going to breweries and wineries. We have a few favorite cities near us, like Charlottesville and the surrounding wine country in Virginia, and Portland, Maine. We've been there with enough frequency that we've developed a sort of reputation as the go-to experts for those areas, and have sent a long e-mail itinerary and travel guide to our close friends probably 10 or 15 times for each place. Sometimes our friend doesn't drink alcohol, so we go through and scrub all the breweries and wineries. Sometimes they're gluten free, so all of the pizza and bagels we love get cut. After doing this several times, we realized it would be cool to have an app to do this. So that is my side project! It will be part Canva, part Facebook Recommendations, maybe part knowledge-base? Filterable lists, creation of itineraries, notes about each Place. Export to a static site with a link you can share. It is already integrated with Google Maps and Places APIs, so it's pretty easy to get up and running. The neat thing is, as I mentioned above, it has filters. So you can tag places with "winery" or "vegetarian" or something, and when you're crafting your collection of places for your friends, you can filter on those tags really easily. You could just click the "winery" tag to instantly create a "Virginia Wine Guide". I'm not totally sure it has broad appeal, but I'm hoping a few travel bloggers might get some use out of it. V3 will probably have some sort of "export to CMS" feature.

I've been (slowly) doing Advent of Code 2019 on an STM32F303 microcontroller. I want all of the problem data to be stored in the binary, with the answers being output on a display. Most of my time so far has been spent on getting the clock working, and compression/decompression. I only have limited space (256KB), and the 20 of last year's problems I solved take up 221KB, so I decided the best course of action would be to store them compressed when possible. I did consider just using compression library, but decided against it partly because it would be more interesting to write it myself, but also having a quick look I couldn't find one that could do decompression without needing additional temporary storage. It's not that fancy, just LZW with a multi-stage compression to optimize the dictionary. Because of how many of the inputs work, you can often handle it in smaller chunks (e.g. one line at a time, I called them records), so the inputs have a small amount of pre-processing on my PC to split them up into smaller chunks so the entire input doesn't need to be held in RAM at once. Of course, not all input data will compress well, some will even "compress" to a larger size, so I've also abstracted over the data storage so that it can handle reading records from compressed or uncompressed inputs. I've done 4 days so far, and none of the inputs have compressed. Total runtime is 3.24 seconds (that day 4...). Current state can be found here for the morbidly curious: https://github.com/Measter/AdventOfCode2019 https://github.com/Measter/AdventOfCode2019 Spoilers are in the mcu/src/challenges folder.

Cool to read about all the various things people are doing. I'm building a virtual tabletop for tabletop roleplayers that play narrative driven games and theater of the mind style games. I'm using text parsing to accomplish different tools for storytelling and improvisation. Believe that is the quickest way for a GM to produce content and rig their games. The tech stack is Svelte and Sapper with MDSVEX and Pouch/CouchDb/Websockets. The database part has been the hardest so far and haven't gotten that far. Got some decent character sheets out there but just using local storage for now. Got working slide decks, rollable tables and interactive fiction in dev but knitting it all together is a big job.

Been working on a service to let you listen to the web -- similar in function to the audio part of the Pocket app. Mostly using AWS Lambda and SNS. Some occasional weirdness in stringing functions together -- might do more with Step Functions. But weird part is some calls just seem to hang and never return -- unless they get a clean/new function of their own. Using Pythom 3.8 with Boto3 library. But generally amazed with what Lambda seems like it might be able to do if I can get it humming. http://readonthegoapp.com/ http://readonthegoapp.com/

carmen_sandiego 6y ago
Step functions are interesting in theory but they become quite messy in my experience. Are you using Chalice for your Lambda functions? Or something else? What kind of problems are you having with SNS? With Chalice it should be pretty easy to just trigger on SNS messages that come after each step, though I’m not sure which steps you would need for your app. Is it TTS with Poly running async or something?
