Ask HN: What non-AI products are you working on?

I’ve been working on a synthetic DNA assembly company. Basically, I figured out how to assemble DNA for people at a fraction of what it normally costs, so they give me a sequence, and then I make it in real life for them, then ship it to them.

Most of my customers have been AI protein designers, ironically. Turns out SOMEBODY has to wrangle atoms in the real biological world and that’s me!

After almost a year of work I finally smoothed out all the kinks in the process, so can now go from a design to synthetic DNA in a cell in about a week (not counting oligo pool synthesis time). I can do about 600,000bp per week, which is large enough to synthesize the smallest bacterial genome (each week), tho I only do about 1000bp fragments. I’m also completely bootstrapped and self funded, and only get help from my several opentrons robots

You know how sometimes the gift you really want is cash or a gift card, but people often prefer to give you physical gifts that you can open and admire?

Imagine a line of faux jewelry that is marked up to real-jewelry prices and that, unbeknownst to the gift giver, comes with a hidden gift card code. So somebody asks you what you'd like for your birthday and you say, "Oh, I'd really like some Lagniappe brand jewelry," and they go out and buy you a $50 necklace that's actually worth only a buck or two, but has a gift card code worth $45 on the underside of the box.

You thank them profusely for the lovely necklace, they feel good for having bought you something besides a gift card, and you feel good that you can put $45 toward a new washing machine.

I'm working https://annotate.dev, a tool inspired by the Stripe documentation, to let anyone create step by step code walkthroughs. Here's a sample of a walkthrough you can create: https://annotate.dev/p/hello-world/learn-oauth-2-0-by-buildi...

Would love to hear any feedback thoughts!

A new terminal emulator [0] from scratch. It's native and cross-platform for Windows, Mac, and Linux.

This is a product with a history of overpromising on the release date, but I'm being more realistic with the roadmap and streaming progress on Twitch.

If it helps think of it as the indie, non-AI version of Warp [1].

I've been building algorithmic trading models for the last 4+ years. After trading them successfully with my own capital for more than a year, I launched https://grizzlybulls.com as an alternative to the traditional hedge fund monetization path.

Since launching in January 2022, we've significantly outperformed the market with lower volatility and reduced max drawdown:

Model - Return - Max drawdown

S&P 500 (benchmark): +9.91% -27.56%

Platinum: +45.34% -16.48%

Gold: +39.53% -19.12%

Silver: +17.24% -22.96%

Bronze: +14.12% -23.93%

Vix Basic: +9.81% -24.23%

TA - Mean Reversion: +17.77% -19.92%

TA - Trend: +17.29% -24.98%

This is an unleveraged, apples to apples comparison. These are not high frequency trading models. Most of them only make a trade every 2-4 weeks on average. During long signals, the models are simply long the S&P 500 and during short signals, they go to cash. This can be implemented very tax efficiently by holding a core ETF long position that never gets sold and then selling S&P 500 futures (ES or MES) of equal value to the ETFs against the long position. This way your account will accumulate unrealized capital gains indefinitely and you'll only pay tax on the net result of successful hedging. The cherry on top is that the S&P 500 futures are section 1256 contracts that are taxed at 60% long term / 40% short term capital gains rates regardless of the duration they are held.

The models use a variety of indicators, many of them custom built. Most important are various VIX metrics (absolute level, VIX futures curve shape/slope, divergences against S&P 500 price, etc), trend-following TA metrics (MACD, EMV, etc), mean-reversion TA metrics (Bollinger Bands, CMO, etc), macroeconomic (unemployment, housing starts, leading composite), and monetary policy (yield curve inversion, equity risk premium, dot plot, etc). They've been backtested very cautiously to avoid overfitting.

Long-term (decades), no-subscription archival storage. Essentially, you buy a block of space, upload your data over time, and it gets distributed when you need it (if you lost a primary backup), or on your death (to friends and relatives, or whoever you choose), or on a specific future date.

It's a mashup of a safety deposit box, time capsule, and deadman switch.

It's not ready yet, but will be ready in a few weeks. If you're interested, I would really like to talk to you. My email is ethan@ethanmye.rs

FWIW, I did use chatgpt to write a lot of boilerplate JS and fix my bootstrap templates!

I'm working on a money laundering simulator video game.

A privacy-first personal finance stack, with free and SaaS versions, with "power user" developer-friendly data analysis.

No ads, no data sale, E2E encryption, localhost option, basic budgetting and transaction parsing, but for power users allows spinning up a jupyter notebook to play with your financial data.

I've been working on a local-first personal finance/expense tracker called Tender: https://tender.run

Tender runs as a PWA and uses the Automerge crdt and sqlite via wasm. The app more or less runs entirely in your browser (works offline!), though our server proxies connections to pull in plaid/splitwise data.

Feature-wise, we're targeting folks who do want to manage their expenses but not have to do fine-grained budgeting. There's tools for tracking getting paid back and a splitwise integration as well. The app is desktop-centric right now, but we're working on getting a good mobile workflow together too.

Since everything is browser-based, it was actually quite easy to get a demo sandbox environment working. You can give it a quick spin here: https://demo.tender.run

I'm working on a Wordpress-replacement written in Go, distributed as a single static binary with SQLite/Postgres for db and Disk/S3/GCS for storage.

A simple, self-hosted RSVP system for parties, now that FB is no longer a unifying platform for my social circle.

And a "mood meter" mapping app that puts anonymous reports of how folks are feeling on a world map. I don't quite have the skills (yet) to do this latter project, so we'll see how much time I have to dedicate to it.

My own photogrammetry pipeline because I'm fascinated by the tech (automatically create 3d models from photos). There are also a huge number of commercial applications but I haven't addressed one well enough yet.

https://beholder.vision

So far I've built a first pass of the pipeline using C++/CUDA and used it to power a SaaS and desktop photogrammetry app (free for personal non-commercial use). Got some useful feedback from the initial release of the desktop app back in January and I'm hoping to spend some time iterating to improve further later in the year (currently contracting to generate some funds).

It's possible that some deep learning generative AI network will take over all 3d model generation from photos tasks in the future but I'm hoping/betting that a) classical techniques will give higher resolution, more accurate results for a while yet and b) even if deep learning matches in accuracy and resolution it will always be possible to get better efficiency for big chunks of the pipeline using classical techniques.

For the last three years, I've been working on https://onlineornot.com

It's uptime monitoring (and status pages) for software teams.

In my words, the aim is "monitoring that doesn't suck" - I've worked at companies with proactive monitoring like OnlineOrNot before, and was surprised how little the incumbents are innovating in the space. One customer once told me "f*k <vendor>, all their system ever did was alert us when we weren't down".

I'm currently working on a self-documenting (OpenAPI, rolled it myself: https://developers.onlineornot.com/) API that'll let folks use terraform (or even just the API itself) to setup their uptime checks, cron job monitoring, status pages, even their teams.

A developer happiness product, https://workdna.com. It sends out employee pulse surveys that are purpose-built for dev teams and don't suck to fill out.

Lots of companies just cobble together a Google Form full of irrelevant questions, send it out, and throw their hands in the air when nobody fills it out.

WorkDNA surveys your team on criteria like CI/CD reliability, test flakiness, PR feedback quality, job satisfaction, and psychological safety. The surveys take 20 minutes to set up, 5 minutes to fill out, and are completely anonymous.

I'm building https://ambiph.one, an ambient music/white noise/soundscape web app. It's a free alternative to apps which have a monthly fee or are covered in ads. Lots of lovely feedback from people who've found it useful for sleep, tinnitus, focus, ADHD etc

Just launched a PWA and now working on more mixing features like spatial audio, reverb and high/low-pass filters to let you create even more immersive sound environments.

https://majorpager.com - Very simple on-call rotation scheduling for small teams!!! I even toyed with the idea of putting a `#noai` hashtag on the homepage.

OpenPV is a website to analyze the potential of PV installations for electricity production on your building. It's based on openly available 3D building data and does a shading simulation in the browser using WebGL: https://openpv.de

https://weexpire.org - An opensource tool for creating emergency notes that can be read by your trusted contacts only after your death or if you are seriously injured.

I am building a macOS app to help reduce screen strain and dry eyes due to prolonged screen use. It's called LookAway -- https://lookaway.app

Been working on making learning German just a little bit more fun with interactive stories: https://learnoutlive.com/stories/

Just for fun, I'm writing an internet forum software from scratch, strongly inspired by phpBB and the likes.

It is split into an Angular UI, C# ASP.NET Core RESTful API and postgres database. I aimed to let EF Core handle the data model in the database and am pleasantly surprised by how well it works. Also updating the database is a breeze with its migrations.

The features of a forum seem easy enough, but I find it difficult to detail it out into the data model at times.

I’m working on a small side project that allows you to react to any URL with any emoji.

https://opinionmoji.com/

It’s mainly an excuse to learn some new things (HTMX, Prisma, DigitalOcean, etc.), as well as get comfortable building and shipping something from scratch on my own.

My goal is to eventually see large (and funny) swings in reactions in realtime.

An open-source, type-safe http client to your postgresql database. It let's you access your database directly from your react components. It's fast, safe and performant. Think Graphql but you don't need to implement resolvers, it's all generated from your database schema.

If this sounds interesting to you, ping me (email on my profile) :)

API fuzzer built, currently supporting generating data from jsonschema but now expanding into also fuzzing grpc apis based on protobuf files.

It's fun and I don't think LLM with all the uncertainty would fit as well since you want to cover the whole input space.

Hope to charge 99$ or something per year for it but I don't know if anyone would pay for it :)

I’m working on https://langible.com, a language learning app intended to be fun like Duolingo and effective like Anki.

Would love to hear any feedback thoughts!

We’re working on a privacy-focused iOS app that enables you to track anything. It’s called Reflect. The app enables you to answer questions like “how does meditation affect my mood” or “how does this new supplement intervention affect my sleep”. We already support detailed visualization and correlation between all of the metrics you track and are working on some very exciting features to make self-guided discovery even easier.

Here is the link to the app: https://apps.apple.com/us/app/reflect-track-anything/id64638...

I’m building a crawler for remote job postings. As well as a daily email that emails the latest remote jobs found in the past 24 hours to people who sign up: https://bloomberry.com/remote-jobs/

So far, there’s more than 1500 subscribers after a month and a half

Over the past few years, I've built up a bunch of tooling for virtual D&D/TTRPG games I played with friends. DM prepping, note sharing, inventory management, scheduling, etc. And all of that with Discord integrations so you can pretty much manage everything from a Discord server.

I'm currently in the process of converting it to a proper commercial service and making it available to others. If this sounds like something that would be of use to anyone, I'd love to hear from you! Email is in my about section (or just respond here).

A place to connect the books you want to read with friends who already own them, and vice-versa. Imagine a distributed library composed of your friends’ books.

Encouraging sharing with friends and starting conversations about topics you might never have considered having not known they were into the same books as you.

Very rough draft but it has the core functionality, even if it’s a bit cumbersome.

"Boring enterprise software".

A manufacturing focused ERP system using SvelteKit and SQL Server. These systems are typically made with Java and it's becoming clear to me that it's massive overkill when SQL Server is (or can be) doing most of the work and the application is (or can be) a thin layer between the user and the database. Using only one language, with perfectly matched types and validation schemas for both frontend and backend is a huge productivity win. Some may sneer at JS but my product running on Node is snappier than the competition and I think I can develop quality features with good UX faster P4P (only a 2 man team).

In one week we have our anniversary for CloudCamping - a property management software for campsites. It is targeted for the European market at the moment, mainly the german market, because there is not much digital infrastructure in this space yet. In a nutshell: campsite administrators can create and configure their campsite and enable guest to book a place online.

https://github.com/U8String/U8String which is a UTF-8 string library for C# that aims to offer rich and performant API to replace standard string for scenarios where you do want to consume UTF-8 directly. I'm working on it since last summer actually, it turned out to be much higher complexity project than expected :)

Also comes with a few niceties like the ability to directly consume Streams, Sockets, WebSockets and SafeFileHandles with U8Reader (sync/async) that solves painful and error-prone manual buffer handling when reading lines/segments/messages. It is kind of like higher level Rust's BufReader.

I'm making a small compost freezer. This way, while your compost is in your kitchen and before you put it in the municipal compost bin outside, it doesn't smell, isn't wet, doesn't attract flies, and the bag doesn't rip. It has the form factor of a small trash can and uses a TEC for cooling.

I have been frustrated with how project management tools make it hard for engineering teams to see the impact of their work on the product. I built Beacon (https://anvilyard.com/beacon), to fix this. Instead of focusing on moving a ticket to done, I am trying to get teams to think of how their tickets get the team closer to a product goal. I know there are a lot of cultural elements at play in an organization that affect how teams measure their progress, but I am trying to shape the tools we all use to make it easier to focus on end goals, not just features.

Working on Lungy:

https://www.lungy.app

It's an interactive breathing app (responds when you breathe). Initially for stress & anxiety, we're developing a medical device (SaMD) for asthma + COPD.

I'm working on Edna https://edna.arslexis.io/

It's a web-based scratchpad and note taker for developers and power users.

It sits somewhere between Obsidian and Simplenote.

It's particularly optimized for keyboard navigation: Ctrl + K / ⌘ + K to open note navigator where you can quickly create new note, switch between notes, delete notes.

Even though it runs in the browser, when running on Chrome you can store notes in a folder on disk and share between computers if that folder is replicated via DropBox / OneDrive / Google Drive etc.

I’m working on an app that ties a tech stack to psychological configurations so we can stop the “How many times did you mention Typescript” game on resumes and applicant tracking systems. The result is that HR can find diamonds in the applicants who might not match the precise keywords but can nonetheless do the job.

I'm working on a very experimental music generator: https://app.bars.ai (I regret my domain choice). It's free to use and you can play around with it pretty easily.

The idea is that you have a "framework" that you can change for what you want the music generator to produce. You can download the MIDI files it produces as well.

A todo app for recurring personal projects. I found that breaking projects down into simple tasks really helps with my procrastination, but existing apps don't make that process too easy and quickly get cluttered.

My prototype lets me create project templates (that can contain other projects) and I can instantiate an arbitrary amount of them. Triggers can be a time ("every quarter") or some logical threshold (e.g. failing three workouts puts a "review fitness plan" action on my schedule).

It's my first real coding project and almost certainly too big, but it's been very fun to use so far and I already have ~50% of my ADHD social circle interested in the alpha.

I'm building a trading terminal tailored specifically for scalping traders, prop firms and brokerages https://stakan.io.

Coming from a trading background myself, I've worked for trading desks and quantitative trading firms, so I've seen many tools used by professionals that are not popular among retail investors, are not very well-known, or exist in the form of heavy and hard-to-get desktop apps. I’m trying to build something web-based, lightweight, and approachable, hoping to introduce a broader audience to these tools.

I'm working on Astral Divide, a 2D game about space travel, exploration and automation. The concept is quite unique, but inspired by games like Starbound, Terraria, Factorio and minecraft.

I've been working on a social link sharing site called lynmki that allows you to follow a subset of someone's interests rather than having to follow everything they post. E.g. Someone posts lovely examples of typography, and also about events on in their city but you live halfway across the globe so just want the typography.

I'm focussing on smaller circles, avoiding "algorithmic" feeds (aware sorting by reverse chronological order is an algorithm), and no advertising.

It borrows a lot from the greats like HN, Delicious, etc. and there's a long way to go (I just added likes last week) but people are already finding some nice links from it!

You can see it at https://lynkmi.com/ and I'd recommend reading the about page for even more. If it sounds interesting to you please sign up to the waitlist—it's very short!

I'm also building it in public so follow along if you want: https://twitter.com/TheOisinMoran/status/1725929527761596434

Nix-based PXE booting. It can boot different images than your NixOS-based system configurations, but the main focus has been to support NixOS. We even have a system which is able to scan your hardware pre-boot, and then launch the initial ramdisk with a kernel which has all the required drivers pre-installed. https://github.com/majbacka-labs/nixos.fi

I am productionizing a golang project which I have working ... it parses an input image at the pixel level to synthesize its audio equivalent ... inspired by a 3Blue1Brown video on Hilbert Curves ... as it traverses the entire image pixel by pixel it assigns to each pixel an audio frequency which it increments for next pixel ... in doing so it collapses the 2D image into a 1D line of pixels ... then it engages audio oscillators at each element of this line at the assigned frequency with volume determined by the light intensity of the respective source pixel ... it then aggregates all these audio tones into a single tone which represents the source input image ( inverse Fourier Transform ) ... entire process above is reversible so the system can go from image to audio as well as audio to image ... goal is to allow Blind people to see with their ears ... alternatively it can allow the Deaf to hear with their eyes ...

https://www.osomatsu.net/ — a little recipe writing and sharing website that me and my wife (and some close relatives) have been using over the last few years. Have got plenty of ideas to implement on it, but it works well for us as is at the moment. People can request to join for free if it could be useful for them too.

There's certainly a smattering of machine learning algorithms involved in some of the software components, but I'm working on Zipline's next generation "platform 2" delivery drone. As an embedded engineer, something has gone horribly wrong if we're trying to solve problems with AI!

I've been working on Codemap, a code visualization tool for many programming languages (JavaScript, Python, Go, Ruby, Terraform).

https://codemap.app

It parses any given codebase and visualizes all function calls as a hierarchical graph. Quite useful for onboarding new team members, digging through old codebases, or simply debugging issues.

You can further tweak the graph for various use cases. For example, a frontend engineer can view the dependency graph of all UI components, while an infra engineer can view connections between all cloud resources defined in Terraform.

Working on an universal search bar for the cloud era... Started as a university project, now building it with 2 friends, private beta is ready, will become public in a few days... It's called Owledge and we are learning so much things

I built a tool to help automatically conserve email storage (so you don't pay for more).

I'm building a gamified habit tracker, similar to Habitica[1], but simplified in some ways, and with offline support. My biggest issues with Habitica are their lack of offline support (even on mobile), and their extremely downtime-prone servers. My goal is to make something more pleasant to use.

I don't have a link to share since it's still fairly early in development, but I'm making good progress!

https://hyperpaper.me/ – rich, customizable planner pdfs for e-Ink tablets. I have another related project that I'm slowly working on, essentially an RSS reader that sends daily pdf digests/newspapers to your tablet.

Both are very fun and rewarding, and I love building things that help spend less time in front of a (glowing) screen.

I'm working on a tool that easily allows you to theme your UI using CSS variables called Blueberry. https://www.getblueberry.io/

The idea is that each CSS variable becomes a widget and then the Blueberry endpoint will serve those variables so you can let your users customize profile pages/portals and other places they integrate with you UI.

I'm working on a tool for sharing things like API keys using encryption apis built into the browsers, https://www.oncer.io.

What I'm working on at the moment, and am sort of stuck on, on is how to make a web app doing in-browser encryption secure - since the server delivers the code that does the encryption in the browser, users sort of have to trust the server anyway to deliver that code. I would like to at least somehow, maybe through a browser extension, assure the user that the version of the web app running in the browser is at least is the same as the build output for a given release in the repo on GitLab/GitHub/the like maybe... then it's sort of like 2FA in the reverse direction, 2 sources (https server connection + extension doing code check) confirm that the real web app has been delivered to the browser.

Appreciate any thoughts on this head scratcher! Maybe there's some way to assure the web app code integrity I just don't know about! :)

Creating the best place to discover and distribute Christian apps and tools: http://faith.tools

While some may not see this as a problem, it’s actually kind of hard to find great Christian apps in the sea of old blog posts of top 10 apps all taking about the same apps

I’d consider myself an indie hacker and built many tools for Christians, but later discovered there’s no great place to distribute those apps. Hear me out. The app stores are good, but they won’t feature a Christian app as app of the day. It makes sense to not prefer one religion over another as a major corporation. What it does do is leave a hole for Christian app makers

Thus https://faith.tools was born

Once the strategies are defined, the service scans the market in real time on their watchlist and alerts the users if the conditions required for their strategies are present.

I'm working on a stock portfolio management app: https://itako.app/

After diving a bit into finance last year, I found the book "Smart Portfolios" by Rob Carver, which basically aimed at teaching simple heuristics to help create and manage robust stock portfolios. Sadly this book has quite a few simplifications that were valid at the time of writing but are not anymore (ie. interest rates ~= 0). So I set myself to re-implement this a bit properly in a tool for me and eventually other people.

It's up and running online but still a work in progress. It only work for US stocks and the charts can sometimes display non-sense.

I’m working on a nutrition tracking app for iOS called FitBee (https://fitbee.app). There’s been a huge number of “AI” based products in this space but they’ve all been relatively bad in terms of accuracy and reliability (eg the Humane AI pin demo). At some point I’m sure I’ll introduce some AI based features into the product, but for now I’m focused on making it the fastest and most convenient way of tracking your nutrition.

I'm building a set of tools to work with OpenAPI specifications in teams.

Some of the workflows I'm trying to unlock:

- Track every breaking change pushed to your API and notify your team on Slack and e-mail

- Generate a changelog from your OpenAPI automatically

- Generate mocks for every endpoint to share with your frontend person/team

- Public, private, and password-protected API reference pages to share with partners

Here's a link: https://frevo.dev (still in early access)

https://github.com/wong-justin/fmin - I'm working on a file manager for the terminal. A little like Midnight Commander, and a lot like fman. Features: jump to directory (like zoxide), filter as you type, a command palette, and custom commands through shell scripting.

Simple app for managing your bike workshop

https://flatcal.com - a service which will allow to consolidate multiple calendars into a single one for easy sharing with others. For people who organize their time in separate calendars by choice or by necessity. F.e. having personal Google Calendar, corporate Outlook Calendar for work, and maybe another one for freelance. No AI involved, just a good, old processing pipeline. Which makes the service pretty flexible and allow to pre-process the events before merging them into a new calendar, i.e. anonymize events, change their type, filter them out, add some buffer time for rest, etc.

I've expanded it to a WYSIWYG chart editor at https://quickchart.io/chart-maker/, which lets you create an endpoint that you can use to generate variations of custom charts. This is useful for creating charts quickly, or using them in places that don't support dynamic charting (email, SMS, various app plugins, etc).

I messed around with some AI features, mostly just for fun and to see if they could help users onboard. But the core product is decidedly not AI.

A desktop app that helps you stay focused on your most important tasks every day.

It uses the microdata and json-ld documents embedded in the page to find the content you actually want to see. No need for AI/LLM extraction.

I seldom work on AI. For a few years, my opinion has always been: each wave of AI uses different technology. I don't find a continuous flow in this domain, nor do I understand its underneath better.

So, investing in AI is a large risk: back to my university, the popular AI framework is a neural network, logistic regression, supported-vector machines, etc.

Instead, I spent time working on data infrastructure, which keeps evolving but follows a somewhat consistent direction. If you look at databases, the essential building blocks are identical to those fifty years ago.

I first worked on Apache Flink and became a committer after one year as a contributor. And then Apache ZooKeeper and Curator, so did become a committer / PMC member. Later TiDB / TiKV and now GreptimeDB. The knowledge and experience is reusable.

I've been working on an open source project on/off for the past couple of years called ssh-sync, written in Go. The goal is to securely share SSH keys across multiple machines (avoid copy-pasting) and auto-generate new SSH configs based off of the user's current operating system (so your key paths are never wrong again).

There is still work I have to do before a v1 release but definitely interested in feedback. https://github.com/therealpaulgg/ssh-sync

I'm working on a personal finance aggregator, as a Mint.com replacement. I started it a few weeks ago, after learning my mint account would be shut down and replaced with Credit Karma. I can hopefully get it launched in 1-2 more weeks.

I learned since starting that this field is saturated; there are many options... including several going through strong marketing campaigns currently! I'm going to still release this because it's mostly done, and it'll be something I use, even if no one else does; advantage of being able to customize it.

I do think I can do this better than other options in these areas - A: Faster and more responsive (by virtue of not using frameworks, tracking, analytics etc) B: Respectful of the user. Ie, no marketing email, compact site designed so you spend as little time on it as possible etc.

However, when I read this thread, it makes me not feel great about it, since it's not original or cool; not something contributing to mankind's advancement.

I'm working on a "low code" web app that helps developers build web apps (not marketing or blogs or e-commerce sites). Create your data models in the app and get an API, a database (or connect your own), and a Next.js app with all of the scaffolding, models, forms, validation, API calls, policies, access and authorization, etc. ready for you to use and customize.

Laid off last fall, and while looking for a new role I've been working on an old idea I had for a MIDI sequencing app. It's meant for live electronic music production, so it's not a full DAW for composing and editing tracks or anything like that. It just records notes for different MIDI devices/channels and loops them back over a selected number of beats. There are some other features as well, like an arpeggiator, but it's pretty basic so far. I've been meaning to record a demo video with real audio, but I'm not actually a musician myself so I haven't come up with anything presentable yet.

I'm building an Open Source Loom alternative. Loom was bought by Atlassian in October last year for almost $1 billion. ScreenLink.io is a privacy focused alternative to this

The main focus on the product has been working on a cross platform application that can record and upload screen recordings, then on the backend it has been everything else to handle this

The source code is available here https://github.com/mangledbottles/screenlink

Scratching an itch with a personal project: https://hnr.app/ "HN Reader"

It's supposed to be the API layer for a Mac app while I learn Swift, but I got carried away with the web view I was using to debug and ended up with a usable HN homepage heavily inspired by hckrnews.com

I made an image host where you pay: https://imgz.org/

I just launched paid subscriptions to Bernard (https://bernard.app), an automated broken links checker for websites and got my first paying users.

These days I am taking a break and looking to "pivot" it into a more complete website monitoring tool, that not only scans for broken links, but also offer uptime monitoring, page speed and scans for all sorts of issues that might affect your user. Basically a one-stop shop for everyone that runs a website.

This is a product I would love for myself, but I am unsure if it is a good idea to expand the scope of a product that originally had quite clear and "modest" goals: to check for broken links.

I've been working on a no-code/low-code serverless platform for building/running web applications: https://saasufy.com/

Some unique selling points are:

- Apps are defined as declarative HTML. It's possible to build complex apps using only HTML + CSS and no back end code.

- Supports the creation of complex filters/views via a simple UI, with indexing for fast lookups.

- Collections and records update in real time.

- Efficient; real time updates only reach users who are currently looking at the affected resources/views.

- Scalable; behind the scenes, both the database and pub/sub mechanism for delivering real time updates support sharding.

- Spam prevention with rate limiting and backpressure limits.

I'm working on a new type of Windows security app called SpyShelter https://www.spyshelter.com.

I'm working on the Synthetic Data Vault, a set of libraries to generate realistic synthetic data. We have an option to use GAN models but we've found that Gaussian & other copula models work great because they're faster and more user configurable.

It's not a commercial product but I've spent some time building a Magic The Gathering deck builder[0]. I want to build a VTT engine but I feel like if I'm gonna receive a cease and desist letter from Hasbro that'll be the thing that triggers it. ¯\_(ツ)_/¯ it was mostly a 2 week project to learn Go and HTMX anyways....

I'm deeply engaged in rewriting my own data processing software from Elixir to C. I've already reduced the number of dedicated servers from 3 to 0.1 while scaling traffic and handling larger amounts of data. My goal is to optimize it for Raspberry Pi, just for fun... and it's also more ecologically friendly this way :)

By the way, I'd appreciate a programming partner with whom I can discuss security issues in C code. I would gladly exchange code review sessions. Is anyone interested here?

I've started tinkering on a tool for test case management. It would be a direct competitor of things link TestRail or Practitest. QA folks that I talk to seem to feel very underserved by these types of tools, so it feels like there would be demand for something with a bit more polish.

I‘m learning SwiftUI and built myself a no-frills read-later app. The content is extracted on the device, it tracks the reading progress and lets me archive read articles. It can import links via a sharing extension. For the content extraction, I ported the postlight/mercury parser from JS to Swift. It’s easily my second most used app by screen time now, seems like I hit a nerve. I don’t plan to release it publicly.

I'm working on Rolepad (https://rolepad.com), a tool that brings together candidates (job application management) and hiring managers / recruiters (better candidate experience). The candidate side is pretty decent at this point, working on the employer side now. The first capability this will unlock is keeping the status of the application in sync between the two, for greater transparency and hopefully reduced ghosting. I'm sure I'll eventually start sprinkling some AI in the app, but for now it's much more important to get basic functionality, user experience, and market fit right.

I can't believe I've been working on my JS canvas library for 10 years! Last week it finally passed the 300-stars-on-GitHub mark.

I am working on a data management tool called Ottava. Essentially, it's a tool that enable users to input data in a format resembling a pivot table, allowing them to conduct data analysis without the need for data transformation. For instance, users can create a gradebook with student names in the row header and subject in the column header.

The tool automatically converts this layout into database (unpivot), enabling users to perform aggregations such as SUM or AVERAGE without having to write formulas. Because the structure designed by the user often carries significance, such as organizing dates into columns with a hierarchical structure like Year -> Quarter -> Month.

Users can organize their data with grouped rows/columns and insert aggregations. Simultaneously, Ottava can derive insights from the structure metadata and propose various types of charts for data exploration. Subsequently, users can select the charts they are interested in, choose datasets, or drill down into the charts, providing further insight for Ottava to offer more precise chart suggestions based on user interactions.

Unlike AI with the capability to autopilot, our objective is to build a Mazda MX-5 for data analysis: providing users with both enjoyment and control while exploring data.

I'm working on SparkShell https://sparkshell.dev

It's a free online coding website targeted towards beginners learning Markdown and other frontend tools like HTML, htmx, alpine.js, etc. It has GitHub pages-like hosting and you get your own free sparkshell.sh subdomain for your projects (which can be on your domain while having the source private!). You can also easily install certain libraries and frameworks in a couple clicks without having to deal with package managers or any of the sort. It's meant to be a sort of Repair alternative, but free.

Next month is scheduled for a few projects that are aimed at a broader market than the current products, like an API and a toy/demonstration version for casual users.

Interesting question to me, as I was focusing on AI for most of my career but got burnt out. Getting back to more traditional software engineering was a bliss. Right now, I'm working on our web scraping API SaaS (https://scrapingfish.com/). What I found mildly surprising and amusing is how web scraping happens to have one common thing with AI: you hypothesize on something, run an experiment, draw conclusions, iterate.

I guess I am a little behind in trends. Working on VR/AR app for visionOS, Vision Pro. Social network (like instagram) for sharing panoramas, 360 photos and spatial videos. Pretty fun project!

I've recently started on an RSS Reader that helps minimize doom scrolling by giving users 2 "Issues" a day, a Morning Rundown, and an Evening Recap. As well as Feeds being able to be categorized into user-created "Magazines" to gather content from multiple sources that the user finds relevant to each other.

I'd like to provide a lot of customization options for the user to customize it as they see fit. And ultimately make it FOSS in case anyone else wants to play around with it.

I'm still working on UI wireframes, but I use my site to publically post progress updates. https://www.keoni.dev

I'm working on a developer platform [1] that makes the progression from local development to global deployment way smoother than alternatives.

At some point AI may have a role in the platform. But for now we're focused on much more fundamental problems related to the process of developing and scaling software applications.

BTW we're looking for developers to try it out!

Last week the Android App Store finally approved my GopherGeyser app! It's used to control our sprinkler controller (over MQTT) to turn your outdoor living space into an animal-themed Bellagio water fountain show / splash pad to entertain kids/dogs in the warm months! :)

It's still pretty basic, but I'm pretty proud of it. Even though it doesn't use AI, I used AI to write the app, generate copy, and generate the image assets, as I didn't care to learn Flutter just for this one app and have no artistic ability.

Still continuing to work on https://non.io, which I kinda accidentally launched on hackernews around 9 months ago: https://news.ycombinator.com/item?id=36296695

TL;DR elevator pitch: subscription based reddit-like platform. Your subscription is split evenly between everything you upvote that month. Nonio takes $1 out of your subscription to pay for servers.

One thing I found from the launch was there was a huge volume of mobile users, who didn't have a great experience. I hired a dev to help work on an iOS app for this, which we're building in the open.

I'm working on a canvas that records your pen/brush strokes as you draw on it. https://superpaper.netlify.app/

Motivation is that large-language models have a very straight-forward task of predicting the next token and the dataset is easy to get. With this app I aim to do two things: 1. Gather a fairly large dataset that captures the brush-strokes for various art prompts. 2. Bootstrap an algorithm / model that can decompose any image/art/illustration into brush strokes.

A longer-term goal for this app is to build an auto-complete (Co-pilot or Grammarly equivalent) for art.

I've been working on and off on several smallish apps I use in the kitchen, purely non-commercial.

I shared https://teig.pro a few months ago and it's made substantial improvements since then. It's a recipe builder that recalculates masses on-the-fly and supports adding/editing ingredients -- especially focused on breads. Unfortunately Fly.io seems to have flagged the project and is preventing me from deploying updates without upgrading my account (which is already paid). There are quite a few bugfixes which will be rolled out once that issue gets resolved, or I change hosting.

I also made https://pepcorn.pro quite a bit longer in a similar spirit, but much simpler. It uses your device's microphone to detect popcorn "pop"s, and measures the time between them -- done popcorn usually has ~5 seconds between pops.

I'm personally working on a specialized system monitor software to address deficiencies with a popular enterprise IWMS. It is aimed at companies that do not want to splurge for Splunk and require some specific system admin controls and metrics. There is a forwarder and backend API which will be completely self-hosted. I'm using this project to build some expertise in Go :)

I'm working on https://www.worksapp.com/ - a simple, easy to use project management tool for marketers.

I'm building a registrar, beachfront/, for Handshake TLDs I own.

For the uninitiated, Handshake is a blockchain that democratizes the issuance of TLDs via Vickrey-style auctions. Handshake does NOT handle SLDs (second-level domains, or just "domains").

That's where beachfront/ comes in. I recently presented my progress at HandyCon a couple weeks ago and published the transcription this morning.

https://blog.neuenet.com/post/handycon-presentation

Why do I bother with this? Handshake is a blockchain-based naming system focused on TLDs (and security via DANE/DNSSEC). Other blockchains are focused on finance, data, &c and just so happen to have (SLD) naming systems.

A suite of widgets / tools that many SaaS apps want at some point, but that can be cumbersome to manage and build from scratch, e.g. Announcements, NPS widgets, Product Tours, Feedback widgets etc. etc.

All are creatable and editable without coding skills (after the initial copy-paste setup). So for example, product managers and customer success can manage them without having to bother devs.

The tool is called Sales & Dungeons: https://github.com/BigJk/snd

It’s not a product per se, but I can already see it needing something purpose built in the future.

I’m hosting a 6 week cohort of makers and builders to meet virtually every week and share progress with a demo day at the end. It’s been really exciting to see the response of such a program. People are doing things from crocheting to programming.

It’s totally free and the point is to meet other people making things and to finish your own projects.

Here’s a blog post where I chat more about it: https://iml.bearblog.dev/lets-make-things-together
