Ask HN: Your admittedly useless side projects?

74 points by yscodes 4y ago

What were some side projects of yours that you deep down knew nobody would deem very valuable yet kept spending quite some time on? And do you regret those endeavours?

Ah, the "hall of shame" HN thead I have been waiting for! Too many to recount here, but the one I probably sunk in most time was fauxjsp [1], a dev-friendly reimplementation of java server pages. I don't regret spending time on the project because it was fun, it was time I couldn't/wouldn't have spent on anyting better and I learned a bit about software architecture. And you?

I've spent the last four years now trying to start a business on the Internet (working on ideas roughly two hours per day before work). Each project had valuable lessons (both business and code/architecture) that carried over into the next one. So far I've built: - bill splitting service (2017) I spent days agonising over which new framework to use (this was late 2017 after all), eventually learned to just use the tools I knew (react, node, postgres). I didn't really care about the problem space, so shut it down. - jobs aggregator (2017/2018) I learned that implementation is meaningless to the user if you're not delivering value. I wanted to copy remoteok.io and make it serverless (effectively free to serve traffic), I didn't realise existing sites provided value via their traffic. The reason StackOverflow can charge as much as it did is the millions of page views per month it receives, creating value for its job posters. - appointment scheduler (2018) I built an appointment scheduler, had no real means of attracting users, shut it down. - room booking service (2018) Spin-off of the previous idea, but for meeting rooms. Tried to build the whole thing using Google APIs, eventually got stung by API limitations, gave up (learned not to rely on other's APIs without understanding their limits first). - graphql API monitoring service (2018/2019) Traction again, couldn't find users (tried in-person sales for the first time, too). - site speed monitoring service (2019/2020) Essentially running google lighthouse as a service. had some users, but fixing all the edge cases around chrome/puppeteer/lighthouse across super slow websites was a total pain. - uptime monitoring service (2021-current) Doesn't seem to be as useless as the other projects. Has bought me the MacBook Air M1 I'm typing this comment on now. Rewrote my old graphql API monitoring service from scratch to monitor APIs, websites and web apps, seems to be going well so far. Planning on adding features for incident management. Content marketing/word of mouth brings in the users.

Oddly enough my least valuable project was my most successful (so far, I hope!). It was a tinker project while I was learning Laravel, no target market at all. It was very specific - a database/API of YouTube videos and metadata for a YouTube group, the Yogscast. It ended up being used as the backend data for a viewer-controlled cinema that let users vote on and pick videos to watch during livestream downtime to keep the audience engaged during a charity drive. Can't take much credit, of course the actual video playing code was the meat and potatoes of the operation during downtime and the actual stream content during the daytime, but it was vaguely involved in raising millions for charity haha Regrets none, only reason it's not still about is that it turns out YouTube don't like you making a database of YT videos that you allow others to access, they killed my API key eventually
- somethingor 4y ago
  Interesting! YogsCinema still runs every day during “offline” hours on twitch.tv/yogscast, I wonder what’s backing it now
  - corobo 4y ago
    I would imagine they call the YouTube API directly now. The reason it didn't in the first place is it went from random idea to implemented in about 12 hours originally (h/t Akhawais!)

I collect bookmarks of things I want to read, but inevitably will never have time to read. Sometimes I go back and look and the webpage domain is expired, or the page 404s. But I still meticulously folder and tune my bookmarks I’ve never admitted this to anyone, but it feels good to get that off my chest
- tbassetto 4y ago
  I feel seen. I have bookmarks folders named “To Read $NUMBER” from 10 years ago. Why do they end by a number? Because I create a new folder every time the previous one feels overwhelming.

- arethuza 4y ago
  I think that needs to be coupled to something implementing Douglas Adams idea of an Electric Monk: "The Electric Monk was a labour-saving device, like a dishwasher or a video recorder. Dishwashers washed tedious dishes for you, thus saving you the bother of washing them yourself, video recorders watched tedious television for you, thus saving you the bother of looking at it yourself; Electric Monks believed things for you, thus saving you what was becoming an increasingly onerous task, that of believing all the things the world expected you to believe."
- sodimel 4y ago
  I did the same for a while, but it was a mess (700+ unsorted bookmarks on my main computer, 100s more on others). I tried shaarli, but soon after I tried to build something myself, and I created share-links. It's an open-source Django app that you can self-host, and that lets you store (and share!) links, titles, descriptions, and tags. Then it display them in a nice way (for me : not much css, a simple page with no js). It took some dozen hours to get to the point where it's really usable, and it still have problems now (comments are not moderated, I just realized that you can't add a description in links or tags, but I will fix this soonTM). Here's the link of the repo: https://gitlab.com/sodimel/share-links/ https://gitlab.com/sodimel/share-links/ One cool feature is to set your browser homepage to the url that loads a random page : each day I get a cool article to read/concept to discover! (here's my own instance random link url: https://links.l3m.in/en/random/ https://links.l3m.in/en/random/) That's my useless side project (because shaarli already exist and it's way more mature).

I made an async work collaboration app: https://github.com/async-go/asyncgo https://github.com/async-go/asyncgo I had been working at GitLab, pre-pandemic, for several years and I saw how writing things down was almost like a super power to enable async work. If you start with time zone distributed teams, writing things down in issues/docs just becomes the natural way of working. I also saw that lots of other companies didn't really get it - and there was a leap of faith required to try it, because it didn't logically follow that if you write things down more you can have less meetings. My idea was to build something that provided a really natural place to write things down, and I built and tried to sell AsyncGo as a place for making decisions in a written way. You'd set a topic, a context, and a due date, and then the magic would happen. In theory. The problem I had was that I couldn't find anyone to take the leap and try it. Companies who were interested in async already had some similar process, and the ones who really needed help writing things down didn't get it and I never found a way to communicate it to them clearly. In the end I shut down the hosted version and put an MIT license on it. I don't regret it exactly, I learned a lot making it, but I wish it had helped more people. There's other stuff out there now that's sort of similar, and it seems they are struggling a bit as well, so I don't think the market was really there (yet). Now I'm working on a collaboration app for regular people/teams who want to get better at making videos/streams (https://www.synura.com https://www.synura.com) and I hope to apply a lot of the lessons there.

I wanted to "cut" multiple regions from an image. All the tools allow to "crop" an image, but not really extract all regions. Ended up making PhotoCutter[1]. It is totally useless for everyone except a few. [1] https://photocutter.kiru.io/ https://photocutter.kiru.io/
- landmark3 4y ago
  I don't need it but I like it...and sometimes that's all you need for it to become popular :) Well done
- als0 4y ago
  Cool site, nice one. There's potential to save a lot of time when going back and forth between cropping tools. One of my usual workflows is reading big PDFs and I want to pick out the parts that are relevant to me. I could use a highlighter, but that wouldn't filter out the rest of the document, so I typically use a screenshot tool to grab specific areas and save them as pictures. But it can only make one screenshot at a time, which is a lot of overhead. It would be cool to enhance this site so that it takes a PDF with multiple pages and allow you to do the same for that. But that's probably a lot of work compared to uploading a single picture file!
  - kiru_io 4y ago
    Great idea! I will consider that in the future (could be even useful for me)
- klntsky 4y ago
  You can make it into a nice product. Just make the state save-able (including comments) and share-able by a link. Would be a good tool for designers & their customers to quickly leave some comments.

I have a couple apps that only I use or are used by a handful of friends. For hobby projects, I never regret building things that I think are useful but I can't be assed to try to market them to others. 1. Mototripper - live streams my location when I'm on a long distance adventure motorcycle trip so my kid knows I'm still alive and moving. (e.g. <https://www.mototripper.app/track/~knobbies https://www.mototripper.app/track/~knobbies> - a trip through Finland, Sweden, and Norway I took a couple weeks ago.) Built with Sveltekit. 2. Vatinator - an app to apply OCR to Estonian receipts to claim VAT reimbursement. Built with NextJS.

I have a three year old daughter. In her three years of life, I have recorded hours and hours of high quality audio of her. I've also encouraged her to bang on keyboards and drum pads and guitars, and recorded all of that, as well. I then took that material and chopped it, mutilated it, sequenced and mixed it, and released two albums of what I'm calling "classic industrial music", all under a pretend band name, with the credited musicians being my daughter, and our teenaged dog, who is also featured on many of the recordings. Naturally, I then released these two albums to the world, where they have sold roughly 0 copies. This doesn't bother me, though; that was never the point. It is, in essence, a long-term elaborate "performance art" piece, that is intended for my own amusement, and possibly my daughter's amusement, once she gets old enough to "get" the joke. In the immediate time, I get value out of seeing her enjoy playing instruments and making sounds. And I'm giving her the experience of making music, in whatever way she sees fit, before she ever gets taught a bunch of nonsense about what ways are OK and not OK to make music through more formal training. Any project that naturally holds your interest, is probably worth pursuing, regardless of the overall value to humanity. At least for a little bit. Because you're generally going to walk away with knowledge you didn't have prior to starting it, and benefits you wouldn't have predicted had you not gone down the path at all. Oh yeah, also; don't take advice from me. I make horrible choices, then I commit to them.

This one is one of mine from way back in the day, a 6502-based ternary computer emulator with an assembler, a simple operating system, and a compiler for a dialect of C adapted to base 3: http://tunguska.sourceforge.net/ http://tunguska.sourceforge.net/ It had a user base of like 3-4 russian ternary computing enthusiasts, dunno if it still even compiles. Fun project though. As with all of my projects (even those that bring value to others), I do them for myself so as long as I find value in them I'll keep putting time on them. No regrets. I kinda find my writing funny, very mathematically rigorous and ambitious. http://tunguska.sourceforge.net/docs.html http://tunguska.sourceforge.net/docs.html Not really sure who I thought the audience would be.

Most of my work is stuff that I feel very few people find interesting. Yet, I treat each project as if it is a Fortune 50 corporate initiative; with ultra-high-quality code, reams of documentation, full test suites and/or harnesses, etc. I do it, because the occasional project that I do, that matters, benefits from the habits I establish. I've been working on one of those, for the last couple of years (closed source, so I can't link). It's coming along great.

I trained an ML model on 15K headlines from the local (Dutch) populist newsletter and use that model to tweet a new headline every 30 minutes, for the past three years. To make it look like tweets from the actual newsletter, I take the first few words, run those through google translate, and then use that to find an image on Unsplash to add to the tweet. The headlines frequently make no sense and often have grammatical issues. Yet a couple of times a month someone (often a boomer) interacts with the tweets. Their confusion bring me immense joy.

My local newspaper's online version for years was free to use. Of course, they then added a paywall which kicks in after only two "free" articles per month. Given that I refuse to pay the $3 per month for access due to strong disagreements that I have, politically, with ownership of the newspaper, I decided to build a "paywall bypass" solution as a side project. The solution involved building a small server app that acts as a proxy between my browser and their site. It parses out the HTML representation of the articles, which their paywall script at runtime first obfuscates, then removes from the DOM. This solution, naturally, also avoids my browser loading and requesting a whole collection of third-party trackers and ads - since I'm not "rendering" their entire site, simply scraping relevant portions of the HTML. The kicker: I pay $5 a month to host this on a DigitalOcean droplet. I regret nothing.

I actually haven't started this one yet, but I am planning to write a video game for the IBM 1401 computer, released in 1959. What complicates this project is the fact that the computer uses punch cards for input and a printer for output, making the job of designing a video game for those inputs/outputs a bit more difficult. I will probably start with implementing a blackjack game and then work my way from there to a bit more complex games.

My girlfriend sells self-made clothes online. In 2015 I made her a a small Tapestry 5 webapp to manage her orders and, this was the crucial feature, to determine payment status from her copy'n'paste online banking's transactions list. Today, it has integrations for Paypal, Etsy, Shopify, DHL and HBCI (no more copy and paste, finally) and basically covers the whole order cycle with minimal fuss and gives her a quick way to publish new products which she does a lot as fabrics come in / get sold out. I guess that's not that useless but of course it simply can not be worth the time I spent on it. Yet, I don't regret doing it in the least because for me it literally is a labor of love. Plus, I learned a lot doing it and I can go down crazy paths like this one time I made an android app to cut out the background of her product photos. Didn't turn out to be useful in the end but eventually I did use OpenCV via JavaCV for something else in the software. Currently I am in the process of rewriting it in Kotlin / Multiplatform (JVM+JS) and again, I'm learning a lot and making the software a lot sleeker and more functional.

I create monthly mixtapes of leftfield house, techno and disco, and spend an insane amount of time digging through recent digital releases and then mixing/uploading to YouTube (now working on adding visuals with Disco Diffusion). What blows my mind about this whole process is there is so much new music published daily… In an upcoming mixtape the intro track has been on YouTube for 3 weeks and has received only 3 plays. I want this project to unearth such classic electronic tracks and get them out to a wider audience. I can’t see myself ever stopping this project or ever regretting the time spent. https://youtube.com/channel/UCH57ad2Wx5le11zuCulIyNw https://youtube.com/channel/UCH57ad2Wx5le11zuCulIyNw

A couple of years ago I started architecting transcoding/streaming video pipelines on AWS for my work. It sparked a general interest/curiosity into the internal workings of video compression algorithms, which then allowed me to revisit a subject I've always wanted to try out, datamoshing. Something about purposefully breaking codecs to generate artifacts that lets you peak at their inner workings really nerd sniped me. The most advanced video I was able to create is this datamoshed version of Carpenter Brut - Turbo Killer clip : https://streamable.com/7d9h4b https://streamable.com/7d9h4b. I'm particularly proud/pleased with the transition at the 2:00 minute mark. It still a long way from what I would want to be able to accomplish (as the moshing is still pretty random and looks good only by "chance"), but I'm pretty happy with my progress overall. My long term goal for it would be able to create moshing of music video clips, and sync the glitching to the beat/structure of the music (using Spotify Audio Analysis feature [0][1]). As a sidenote, a tool I discovered and has been a godsend into tinkering with video codecs is FFglitch[2]. It's a fork of FFmpeg with the ability to directly access and modify internal MPEG2/4 values (such as the Motion Vectors, macroblocks, DCT coefficient, etc). Compared to other datamoshing techniques (such as corrupting AVI files with random data, manual key frames deletion, etc) it's order of magnitudes more advanced and precise, allowing you to precisely and purposefully influence the codec, instead of randomly breaking it and seeing what sticks. However its downside is that you have to have a solid grasp of the inner workings of those codecs to achieve anything. Finally, for anyone looking for a good resource to get an understanding of Video Encoding, I highly recommend this[3] github repo as a starting point. It contains a good description of the workings, as well as an amazing references list.

I made a webapp to learn music sight reading [0]. Initially the goal was to help my kids pass conservatoirs' exams, which can be quite demanding, and are usually studied on books. That first goal was reached, my kids passed (this week)! I thought this would interest music teachers, and I implemented specific deatures for them. -- Typically, music students like/love learning to play their instrument (or else they quit), but hate sight reading. I talked to a couple of teachers: they are polite, don't express objections, but don't engage, don't call back and don't use it. I did a ShowHN that gathered 11 upvotes. From that came a couple of users, including one who seems extremely motivated. So all in all this has one serious user. Better than nothing! I certainly don't regret it. [0] babeloop.com

Generating e-books from public sources[0]. I wanted to read the “Stormlight Archive reread” from Tor.com on my Kindle so I generated EPUBs. It kept going forward from there to almost a dozen books now. The most popular is the Google SRE book, but I also wrote code for JK Rowling’s Ickabog, which was published online (and taken down since - I switched to Internet Archive). Needless to say, I’ve barely read most of the books that I’ve compiled, so it sometimes feels like wasted effort.

I have been reverse engineering a 25-year-old proprietary (PlayStation 1 based) system used in a number of well-known arcade games for almost a year, digging into every single detail and uncovering what even MAME developers ignored. The end purpose was initially to enable homebrew game development but, with the prices these boxes are fetching on the used market, I know nobody is ever going to bother. Moreover, as far as reverse engineering existing games goes, the most interesting parts (i.e. the copy protection) have already been figured out two decades ago and most of the games are perfectly playable through emulation. Still, reverse engineering an unknown platform that isn't too serious about security is fun and rewarding.

I've spent the last four years now trying to start a business on the Internet (working on ideas roughly two hours per day before work). Each project had valuable lessons (both business and code/architecture) that carried over into the next one. So far I've built: - bill splitting service (2017) I spent days agonising over which new framework to use (this was late 2017 after all), eventually learned to just use the tools I knew (react, node, postgres). I didn't really care about the problem space, so shut it down. - jobs aggregator (2017/2018) I learned that implementation is meaningless to the user if you're not delivering value. I wanted to copy remoteok.io and make it serverless (effectively free to serve traffic), I didn't realise existing sites provided value via their traffic. The reason StackOverflow can charge as much as it did is the millions of page views per month it receives, creating value for its job posters. - appointment scheduler (2018) I built an appointment scheduler, had no real means of attracting users, shut it down. - room booking service (2018) Spin-off of the previous idea, but for meeting rooms. Tried to build the whole thing using Google APIs, eventually got stung by API limitations, gave up (learned not to rely on other's APIs without understanding their limits first). - graphql API monitoring service (2018/2019) Traction again, couldn't find users (tried in-person sales for the first time, too). - site speed monitoring service (2019/2020) Essentially running google lighthouse as a service. had some users, but fixing all the edge cases around chrome/puppeteer/lighthouse across super slow websites was a total pain. - uptime monitoring service (2021-current) Doesn't seem to be as useless as the other projects. Has bought me the MacBook Air M1 I'm typing this comment on now. Rewrote my old graphql API monitoring service from scratch to monitor APIs, websites and web apps, seems to be going well so far. Planning on adding features for incident management. Content marketing/word of mouth brings in the users.

Oddly enough my least valuable project was my most successful (so far, I hope!). It was a tinker project while I was learning Laravel, no target market at all. It was very specific - a database/API of YouTube videos and metadata for a YouTube group, the Yogscast. It ended up being used as the backend data for a viewer-controlled cinema that let users vote on and pick videos to watch during livestream downtime to keep the audience engaged during a charity drive. Can't take much credit, of course the actual video playing code was the meat and potatoes of the operation during downtime and the actual stream content during the daytime, but it was vaguely involved in raising millions for charity haha Regrets none, only reason it's not still about is that it turns out YouTube don't like you making a database of YT videos that you allow others to access, they killed my API key eventually

I think that needs to be coupled to something implementing Douglas Adams idea of an Electric Monk: "The Electric Monk was a labour-saving device, like a dishwasher or a video recorder. Dishwashers washed tedious dishes for you, thus saving you the bother of washing them yourself, video recorders watched tedious television for you, thus saving you the bother of looking at it yourself; Electric Monks believed things for you, thus saving you what was becoming an increasingly onerous task, that of believing all the things the world expected you to believe."
sodimel 4y ago
I did the same for a while, but it was a mess (700+ unsorted bookmarks on my main computer, 100s more on others). I tried shaarli, but soon after I tried to build something myself, and I created share-links. It's an open-source Django app that you can self-host, and that lets you store (and share!) links, titles, descriptions, and tags. Then it display them in a nice way (for me : not much css, a simple page with no js). It took some dozen hours to get to the point where it's really usable, and it still have problems now (comments are not moderated, I just realized that you can't add a description in links or tags, but I will fix this soonTM). Here's the link of the repo: https://gitlab.com/sodimel/share-links/ https://gitlab.com/sodimel/share-links/ One cool feature is to set your browser homepage to the url that loads a random page : each day I get a cool article to read/concept to discover! (here's my own instance random link url: https://links.l3m.in/en/random/ https://links.l3m.in/en/random/) That's my useless side project (because shaarli already exist and it's way more mature).

I made an async work collaboration app: https://github.com/async-go/asyncgo https://github.com/async-go/asyncgo I had been working at GitLab, pre-pandemic, for several years and I saw how writing things down was almost like a super power to enable async work. If you start with time zone distributed teams, writing things down in issues/docs just becomes the natural way of working. I also saw that lots of other companies didn't really get it - and there was a leap of faith required to try it, because it didn't logically follow that if you write things down more you can have less meetings. My idea was to build something that provided a really natural place to write things down, and I built and tried to sell AsyncGo as a place for making decisions in a written way. You'd set a topic, a context, and a due date, and then the magic would happen. In theory. The problem I had was that I couldn't find anyone to take the leap and try it. Companies who were interested in async already had some similar process, and the ones who really needed help writing things down didn't get it and I never found a way to communicate it to them clearly. In the end I shut down the hosted version and put an MIT license on it. I don't regret it exactly, I learned a lot making it, but I wish it had helped more people. There's other stuff out there now that's sort of similar, and it seems they are struggling a bit as well, so I don't think the market was really there (yet). Now I'm working on a collaboration app for regular people/teams who want to get better at making videos/streams (https://www.synura.com https://www.synura.com) and I hope to apply a lot of the lessons there.

Cool site, nice one. There's potential to save a lot of time when going back and forth between cropping tools. One of my usual workflows is reading big PDFs and I want to pick out the parts that are relevant to me. I could use a highlighter, but that wouldn't filter out the rest of the document, so I typically use a screenshot tool to grab specific areas and save them as pictures. But it can only make one screenshot at a time, which is a lot of overhead. It would be cool to enhance this site so that it takes a PDF with multiple pages and allow you to do the same for that. But that's probably a lot of work compared to uploading a single picture file!

I have a three year old daughter. In her three years of life, I have recorded hours and hours of high quality audio of her. I've also encouraged her to bang on keyboards and drum pads and guitars, and recorded all of that, as well. I then took that material and chopped it, mutilated it, sequenced and mixed it, and released two albums of what I'm calling "classic industrial music", all under a pretend band name, with the credited musicians being my daughter, and our teenaged dog, who is also featured on many of the recordings. Naturally, I then released these two albums to the world, where they have sold roughly 0 copies. This doesn't bother me, though; that was never the point. It is, in essence, a long-term elaborate "performance art" piece, that is intended for my own amusement, and possibly my daughter's amusement, once she gets old enough to "get" the joke. In the immediate time, I get value out of seeing her enjoy playing instruments and making sounds. And I'm giving her the experience of making music, in whatever way she sees fit, before she ever gets taught a bunch of nonsense about what ways are OK and not OK to make music through more formal training. Any project that naturally holds your interest, is probably worth pursuing, regardless of the overall value to humanity. At least for a little bit. Because you're generally going to walk away with knowledge you didn't have prior to starting it, and benefits you wouldn't have predicted had you not gone down the path at all. Oh yeah, also; don't take advice from me. I make horrible choices, then I commit to them.

This one is one of mine from way back in the day, a 6502-based ternary computer emulator with an assembler, a simple operating system, and a compiler for a dialect of C adapted to base 3: http://tunguska.sourceforge.net/ http://tunguska.sourceforge.net/ It had a user base of like 3-4 russian ternary computing enthusiasts, dunno if it still even compiles. Fun project though. As with all of my projects (even those that bring value to others), I do them for myself so as long as I find value in them I'll keep putting time on them. No regrets. I kinda find my writing funny, very mathematically rigorous and ambitious. http://tunguska.sourceforge.net/docs.html http://tunguska.sourceforge.net/docs.html Not really sure who I thought the audience would be.

https://geolua.com https://geolua.com Allows anyone to create geocaching-like adventures controlled by server-side Lua scripting. Neat features are multiplayer support, some included widgets to quickly build a UI (see[1]) and a time travel debugger to fix errors. I knew there was probably no real way to make money from that, but it was fun to build. Unfortunately reception by the big geocaching portals was mostly to no allow linking to it IIRC, so there was also no way to gain any traction at all. ¯\_(ツ)_/¯ [1] https://geolua.com/adventure/all-widgets-demo-132 https://geolua.com/adventure/all-widgets-demo-132

Most of my work is stuff that I feel very few people find interesting. Yet, I treat each project as if it is a Fortune 50 corporate initiative; with ultra-high-quality code, reams of documentation, full test suites and/or harnesses, etc. I do it, because the occasional project that I do, that matters, benefits from the habits I establish. I've been working on one of those, for the last couple of years (closed source, so I can't link). It's coming along great.

I trained an ML model on 15K headlines from the local (Dutch) populist newsletter and use that model to tweet a new headline every 30 minutes, for the past three years. To make it look like tweets from the actual newsletter, I take the first few words, run those through google translate, and then use that to find an image on Unsplash to add to the tweet. The headlines frequently make no sense and often have grammatical issues. Yet a couple of times a month someone (often a boomer) interacts with the tweets. Their confusion bring me immense joy.

My local newspaper's online version for years was free to use. Of course, they then added a paywall which kicks in after only two "free" articles per month. Given that I refuse to pay the $3 per month for access due to strong disagreements that I have, politically, with ownership of the newspaper, I decided to build a "paywall bypass" solution as a side project. The solution involved building a small server app that acts as a proxy between my browser and their site. It parses out the HTML representation of the articles, which their paywall script at runtime first obfuscates, then removes from the DOM. This solution, naturally, also avoids my browser loading and requesting a whole collection of third-party trackers and ads - since I'm not "rendering" their entire site, simply scraping relevant portions of the HTML. The kicker: I pay $5 a month to host this on a DigitalOcean droplet. I regret nothing.

I actually haven't started this one yet, but I am planning to write a video game for the IBM 1401 computer, released in 1959. What complicates this project is the fact that the computer uses punch cards for input and a printer for output, making the job of designing a video game for those inputs/outputs a bit more difficult. I will probably start with implementing a blackjack game and then work my way from there to a bit more complex games.

My girlfriend sells self-made clothes online. In 2015 I made her a a small Tapestry 5 webapp to manage her orders and, this was the crucial feature, to determine payment status from her copy'n'paste online banking's transactions list. Today, it has integrations for Paypal, Etsy, Shopify, DHL and HBCI (no more copy and paste, finally) and basically covers the whole order cycle with minimal fuss and gives her a quick way to publish new products which she does a lot as fabrics come in / get sold out. I guess that's not that useless but of course it simply can not be worth the time I spent on it. Yet, I don't regret doing it in the least because for me it literally is a labor of love. Plus, I learned a lot doing it and I can go down crazy paths like this one time I made an android app to cut out the background of her product photos. Didn't turn out to be useful in the end but eventually I did use OpenCV via JavaCV for something else in the software. Currently I am in the process of rewriting it in Kotlin / Multiplatform (JVM+JS) and again, I'm learning a lot and making the software a lot sleeker and more functional. That's not going to be worth it either, I am sure. Anyway, I wish I had day job were I was in constant contact with users to built them something of tangible utility and value.

I create monthly mixtapes of leftfield house, techno and disco, and spend an insane amount of time digging through recent digital releases and then mixing/uploading to YouTube (now working on adding visuals with Disco Diffusion). What blows my mind about this whole process is there is so much new music published daily… In an upcoming mixtape the intro track has been on YouTube for 3 weeks and has received only 3 plays. I want this project to unearth such classic electronic tracks and get them out to a wider audience. I can’t see myself ever stopping this project or ever regretting the time spent. https://youtube.com/channel/UCH57ad2Wx5le11zuCulIyNw https://youtube.com/channel/UCH57ad2Wx5le11zuCulIyNw

A couple of years ago I started architecting transcoding/streaming video pipelines on AWS for my work. It sparked a general interest/curiosity into the internal workings of video compression algorithms, which then allowed me to revisit a subject I've always wanted to try out, datamoshing. Something about purposefully breaking codecs to generate artifacts that lets you peak at their inner workings really nerd sniped me. The most advanced video I was able to create is this datamoshed version of Carpenter Brut - Turbo Killer clip : https://streamable.com/7d9h4b https://streamable.com/7d9h4b. I'm particularly proud/pleased with the transition at the 2:00 minute mark. It still a long way from what I would want to be able to accomplish (as the moshing is still pretty random and looks good only by "chance"), but I'm pretty happy with my progress overall. My long term goal for it would be able to create moshing of music video clips, and sync the glitching to the beat/structure of the music (using Spotify Audio Analysis feature [0][1]). As a sidenote, a tool I discovered and has been a godsend into tinkering with video codecs is FFglitch[2]. It's a fork of FFmpeg with the ability to directly access and modify internal MPEG2/4 values (such as the Motion Vectors, macroblocks, DCT coefficient, etc). Compared to other datamoshing techniques (such as corrupting AVI files with random data, manual key frames deletion, etc) it's order of magnitudes more advanced and precise, allowing you to precisely and purposefully influence the codec, instead of randomly breaking it and seeing what sticks. However its downside is that you have to have a solid grasp of the inner workings of those codecs to achieve anything. Finally, for anyone looking for a good resource to get an understanding of Video Encoding, I highly recommend this[3] github repo as a starting point. It contains a good description of the workings, as well as an amazing references list.

I made a webapp to learn music sight reading [0]. Initially the goal was to help my kids pass conservatoirs' exams, which can be quite demanding, and are usually studied on books. That first goal was reached, my kids passed (this week)! I thought this would interest music teachers, and I implemented specific deatures for them. -- Typically, music students like/love learning to play their instrument (or else they quit), but hate sight reading. I talked to a couple of teachers: they are polite, don't express objections, but don't engage, don't call back and don't use it. I did a ShowHN that gathered 11 upvotes. From that came a couple of users, including one who seems extremely motivated. So all in all this has one serious user. Better than nothing! I certainly don't regret it. [0] babeloop.com

Generating e-books from public sources[0]. I wanted to read the “Stormlight Archive reread” from Tor.com on my Kindle so I generated EPUBs. It kept going forward from there to almost a dozen books now. The most popular is the Google SRE book, but I also wrote code for JK Rowling’s Ickabog, which was published online (and taken down since - I switched to Internet Archive). Needless to say, I’ve barely read most of the books that I’ve compiled, so it sometimes feels like wasted effort. However, I’ve since put a lot of the learnings from these projects to use, such as while building pystitcher[1].

I have been reverse engineering a 25-year-old proprietary (PlayStation 1 based) system used in a number of well-known arcade games for almost a year, digging into every single detail and uncovering what even MAME developers ignored. The end purpose was initially to enable homebrew game development but, with the prices these boxes are fetching on the used market, I know nobody is ever going to bother. Moreover, as far as reverse engineering existing games goes, the most interesting parts (i.e. the copy protection) have already been figured out two decades ago and most of the games are perfectly playable through emulation. Still, reverse engineering an unknown platform that isn't too serious about security is fun and rewarding.
