alt Hacker NewsAsk HN: What Are You Working On? (June 2025)
What are you working on? Any new ideas which you're thinking about?
Comments
C# playground (compiler explorer) which runs entirely in a browser (via WebAssembly). Started as an alternative to SharpLab which is not maintained anymore. But it can also do some other stuff that I wanted like downloading any compiler version, and compiling Razor. Recently I've added some "IntelliSense" features to improve the editing experience.
I started integrating http://ohmjs.org with http://strudel.cc so you can live code your live coding language
I'm working on a native to-do app that relies on Markdown files for data storage.
One of the same things I was working on in 2015 as well as 2005.
An HP Deskjet 5850. Typical small home/office printer.
Thanks to a brilliant owner years ago who figured out you can use the drivers from the model 9800. A larger-format printer whose drivers seem to cover a lot of ground for printers of certain vintages, easily including ones like this one having more limited paper size options. The printer works quite well on the latest Windows 11 now, it's just not a one-click affair to install like it was with Windows XP.
By this late date, the driver download has been slightly hosed. Files are basically from Windows Vista x64 but are not prepared to install like you would want them to, there is actual uncorrected damage to the structure. Once you unzip the drivers into a C:\drivers\ folder for instance, then after you manually install the .INF file found in C:\drivers\ it's supposed to allow you to later manually select a driver from among a number of similar vintage HP Deskjets. All the driver files for that variety of different printers are right there in the C:\drivers\ folder, right next to that one INF that covers them all. But the install routine can't find any of them because it looks for them in a "hard-coded" C:\drivers\amd64\ subfolder which somebody forgot to spawn.
Then if you manually make a new C:\drivers\amd64\ folder, place an extra copy of the unzipped fileset into C:\drivers\amd64, then install the INF from there, it proceeds to search for the drivers in C:\drivers\amd64\amd64\ and fails to find them again :\
Try it again, pointing at the INF in C:\drivers\, and with the extra copy of the fileset (less the INF) already present in C:\drivers\amd64, then it works.
And that was before "Print Nightmare" a few years ago.
Since then the "normal" steps that follow have gotten worse every year, maybe more often, additional hurdles and barricades keep popping up.
Plus you can only imagine the fun, sharing the printer with Windows XP like nobody knows the difference.
It's almost like Windows is a challenging videogame which keeps coming out with new versions where it gets more difficult to make it through all the levels, and when you do, you reach pretty much the same final goal you had before you got the new version :\

A platform to host virtual races for fundraising events. Think Race Nights from the 90s/00s. Currently working on this with my brother, as we've both been out at risk of redundancy.
Had our first event over the weekend. Now we're focusing on marketing to local social clubs, charities and school groups.
Got a long list of future features and improvements, but this is a solid MVP. Made in react with redux, Pixi.js and prisma with sqlLite for a db.
We have been working on optimizing performing web platforms that scale for businesses primarily engaged in eCommerce or custom web apps. One idea we have been exploring closely is greater emphasis on mobile-first UX and ERP/CRM backend integration for clients that want to have accelerated growth. At eGrove Systems, we are also refining our process around Core Web Vitals and modular development to increase delivery speed and optimization while maintaining flexibility. Would be delighted to connect with others if there are similar challenges.
I am bootstrapping Appio.so
Appio lets you add mobile widgets and native push notifications to your web app within minutes—without building or maintaining mobile apps, hiring developers, or dealing with app stores. You can try it at: https://demo.appio.so/
If you’re building a web-based product without a mobile app, or just want to try Appio, I’d love to chat! You can reach me directly via https://my.appio.so/ or drop a comment here.
I'm thinking about my career and where I'm to go next. Some times I feel I haven't gone deeply enough into the tech I use, and some times I feel like I'm barely scratching the surface of what I've already learnt in my life. I'm not sure what the answer is, at some companies I feel like I'm not enough and at others I feel like I'm surrounded by BS that doesn't deserve a chance. I wonder also if this is the end of my career, but I do enjoy software to be honest, and I love building things even today.
I'm working on FeedSync, which polls RSS feeds and pushes new entries to Discord.
It's built on Phoenix/Elixir and has been pretty rock solid.
Sign up currently requires a card number, but that's something I'm hoping to fix in the next week or so. If you do happen to sign up, I'll set your account to an unlimited free trial ;)
Trying to make out paint for text (essentially a Large Symbol Model). Tokenize renders of PDFs with patches of some sort and see if I can make a multi language monochrome visual vocabulary where I can embed language and document metadata. I want to be able to convert my tax statements into musical compositions and render pride and prejudice as a 80s computer technical manual. Could also allow for direct language translation without the complex language tokenization we have today. Literally visual pattern understanding.
I fixed my poetry website[1] - mainly by ripping out TailwindCSS and replacing it with a few lines of vanilla CSS, and adding a canvas library so I could include some of my graphic poems[2] on the site. I also wrote some new poems to complete the spruce-up.

Was recently working with my daughter decide on colleges to apply this year. Started building https://www.collegedecider.com/ to assist with the process of identifying the colleges based on academic profile, and also, create an action plan for all selected colleges.
Working on a POS for my wife's stationary and office supply store in mexico. Hosted on my on premise hardware raspberry pi. I will upgrade from containers to kubernetes soon. xplaya.com && papeleria.xplaya.com
https://www.quarterbackranking.com
It's a DIY confirmation bias machine for ranking NFL quarterbacks by a variety of stats.
it's a fishing recommendation engine that weights weather, lunar cycles, water turbidity, and a few other factors and generates gear & bait/lure presentation recommendations.
A film screening aggregator website for independent film theaters in NYC powered by LLM agents.
Right now it's able to collect data from more than 30 sites with all very funky html formats with no custom code for each site.
When I began I had around 20% errors/hallucinations, right now it's way lower at around 3% errors in extraction. It's been fun and gave me a lot of experience building LLM powered data pipelines.
Developing BCL, a configuration language not far from HCL. In some aspects simpler than the latter, more advanced in some other aspects (full expression evaluation, very easy binding to Go structs).
Recently reworked said deserialization to Go structs, allowing to handle more data layouts while simplifying the syntax. And having a great co-op with one of the two active users via Github issues.
More to come (functions, cross-reference of data blocks, for example).
https://inspo.dev - The idea is a chrome extension that let's you iterate ridiculously fast on frontend web components - click one button, select the element like you're using Chrome's inspect dev tools, press generate, and 60 seconds later, AI has given you ~7-10 new variations on how you could style that component, with the code ready to implement.
Struggling to get the generated iterations to be up to a standard I'm happy with at the moment, but improving every day!
In my spare time I'm working to finally complete creating my own blog/site.
It's built using Nuxt because I've never really played with Vue before and it seemingly comes with all I need for a static, markdown-powered blog. I guess what's been stopping me was me bothering too much about "When is it good enough to be online?" and "What should the first post be?". But I'm trying to get rid of the perfectionism by just putting it out there and just posting something. I think I'll reflect on this in the first post.
We're working on a Container Registry for https://molnett.com. We don't really want to use Harbour as we want to manage our own AuthN/AuthZ and are fully multi-tenant, so we decided to build our own on top of Distribution.
Going from Manifest to OCI is a bit tricky and performance for calculating total storage based on metadata is hard to get right. But the result is that we own our full registry implementation and can take it any direction we want. Quite happy with that!
gemini-copilot: https://github.com/binora/gemini-copilot
Just trying to make gemini-cli work with my enterprise copilot subscription.
Old guy here. My precious side projects are out the window. My sole "project" is getting my blood sugar down and losing weight. Have no energy for anything else except practicing musical instruments.
My credit rating has literally plummeted 200 points for reasons I don't even have the energy to investigate (I have a pretty good retirement fund, no debts/mortgage/care payments). Just no energy to do anything except hang around trying not to eat.
A free meeting-scheduling tool with all the pro-sounding features without any restrictions or commissions. Think Calendly, but free and much better.
Work with sensitive data without seeing it.
We're building Redactsure.com
A novel technology whose goal is to separate data from interactions entirely. We are building a custom OS whose first goal is to detect, hide, and then use sensitive data throughout any web interface.
Building a new browser rendering layer with real time transformer inferencing is hard but it's been an amazing tech to work on. Long term we think this technology will change the way all remote work is done at a fundamental level.
A C/C++ cross compilation toolchain for Bazel based on LLVM that compiles all target dependencies (CRT, libc, C++ stdlib, unwind libraries etc...) from source.
This means that it can cross-compile C and C++ programs that use the libc (glibc or musl) as well as the C++ stdlib (libstdc++ or llvm-libc++) out of the box without any kind of sysroot.
Hey guys, I can't stop thinking about this idea. So I have 6 years of exp as cloud and devops engineer which means I have spent a lot of time doing ci/cd and stuff. And ci/cd usually runs on cloud which has a cost associated with it. Now i was thinking what if company can utilize the compute of the machines they give to employees to carry out such tasks like ci/cd. Simply put, companies should be able to run ci/cd on employees machines and reduce their spendings. WDYT? if anyone interested we can work on it together.
Working on https://ireact.to/, basically a centralized link in bio to collect feedback, questions, urls, ideas from your community.
Saturated market riddled with alternatives, but I wasn't really able to find low friction way to collect these things that met all my needs. Most of this stuff gets lost in DMs or comment sections, which just wasnt working for me.
Also figured it would be a neat way to re-think paying for a creators attention. IE, giving the option to tip (and soon subscribe to a VIP inbox of sorts).
Still trying to upstream my Wasm SIMD libc optimizations.
Trying _not_ to create another subscriptions for your browser extension platform, but I want to solve the problems with the storage.sync API (limited support, limited data, not cross browser/cross device) for my own extensions, so I'm effectively dogfooding one.
I've added a few exclusive features to one of my extensions for subscribers in addition to settings syncing, and have auth and Stripe redirects and webhooks working, so now at the stage of working out the best heuristics to use for when to sync and connecting the extension to the settings API.

I am working on the world's first end-to-end Database Migration tool, supporting Oracle to PostgreSQL and MSSQL to PostgreSQL database migrations with AI for Schema Migrations. Until now, people used different tools for Schema Migration and Data Migration/Replication. During this process, we ended up building a data migration and replication tool supporting any databases between Oracle, SQL Server (MSSQL) and PostgreSQL databases.
I have been working on https://gametreecalculator.com, which is a canvas on which you can draw a decision tree. Assuming the payoffs you define are zero sum, you can calculate the optimal solution (nash equilibrium) by clicking a button. The code for the "calculator" was pulled from https://actionflop.com, where it's used for GTO poker bots you can play heads up no limit holdem against.
Building a JS implementation of serverlessworkflow.io that runs on the edge.
Wanted workflow orchestration without infrastructure to store workflow JSON/YAML in database/S3/CDN/whatever and execute it on Cloudflare Workers, in the browser, etc.
The magical part about the serverless workflow spec: native JSONSchema support for inputs/outputs at both workflow and task level. This creates composable, Lego-like tools for AI agents - each tool is just a workflow reference that can be fetched on the fly.
Working on final cleanup before publishing.
Building a strong body, goal is to do planche by end of the year!
It’s not something technically inclined or interesting. I used to host a Flash Game, some sort of, Bubble Wrap Bubble Popper. Unfortunately, it went away along with Flash. My site complains of the usual 404 on that page. Early this month, on one fateful evening before I retired for the day, I decided to work alongside an AI Coding assistant and completed it. Since then, if not others, my daughter has popped a lot and lots of bubbles.
After something like 15 years, I'm building again my pc from scratch. I'm learning a ton about those new technologies and how all the pieces fits together. It's a lot of fun.
I've made a utility that uses LLMs to compare specifications against implementations, called "semcheck" (semantic checker). I’ve often found that even though I set up Cursor rules or CLAUDE.md files, the implementation tends to drift away from these documents. I built this utility to be run as a pre-commit or CI step to check that they are still the same.
Hey HN, I built Zookish,
a “voice orb” that lets your website talk: visitors ask questions in plain English, book demos, search resources all with no forms. We’ve seen a 25% engagement lift on beta sites. I’d love your quick thoughts:
Is voice navigation a gimmick or game-changer?
Which use cases or industries excite you most?
Recently relaunched Clares.ca, a free website for Canadian amateur radio training.
The new site has modern basics: Fast and mobile friendly and will soon incorporate the latest updates to the Canadian test bank.
Additionally, I’m adding progress tracking, logins and notifications to keep users engaged. The previous version of the site was just the course and nothing else. This one is more usable.
Working on a automated stock market trading algo. Focused only on swing trading with a fixed index.
Earlier I had some success with a couple of srats, but they aren't working any more. Idea is to have an arsenal of strategies and use whichever is performing better based on recent back tests.
More than the trading part, the fact I can leverage some ML in these interests me, plus quite fascinating how helpful llms have become especially for python programming.
A unified API for online advertising. Think Plaid for ads platforms instead of banks.
Pomodoro technique with a quick shared break online minigame.
It runs a 25-minute focus timer, then launches a 3-minute round of a multiplayer minigame (right now just multiplayer Minesweeper), followed by a 2-minute cooldown with a chatbox
A couple friends and I do this manually, we work on side projects, mute ourselves on Discord, and play random games during the break. This just puts it all in one place.
Only Minesweeper for now, but planning to add a voting screen and a few more simple multiplayer games.
Working on indie photography software (iOS/macOS for the time being): https://heliographe.studio
My most recent release is a camera app dedicated to RAW photography, which focuses on being fast & lightweight & technically precise - I wrote the website to be both a user’s manual and a crash course in photography concepts: https://bayercam.app
I’m working on my next app release, which I’m pretty excited about!
I’ve been working on a platform for devs and agencies that need to deploy multi-platform chatbots/ai agents for their clients or projects.
It’s built in nextjs and Django, with integrations for OpenAI, perplexity and all bedrock models. And MCP of course.
Feedback and requests welcome, I’m terrible at marketing so we have very few users but we use the platform ourselves and we’re super happy with it.
I just released version 1.4.0 of my app ReminderSync for Obsidian!
https://turquoisehexagon.co.uk/remindersync/
The latest version supports dataview tasks format and multiple reminder lists with Routing Rules.
I think the product is pretty much feature complete now so I’ll probably start doing some marketing and move onto coding something new. Sales until now have all been organic.
Prepbook https://prepbook.app a way to collect, organize and consume recipes. You can add a recipe from a link, YouTube video or type it by hand. It's just text, you don't have to fill 27 different text boxes for each ingredient/step. It parses the ingredients and lets you scale the recipe. It has no ads and no spam. It's still in an early phase, your feedback is highly appreciated!
I've been more actively developing PAPER, and expect to push to GitHub and publish wheels on PyPI tomorrow although it's really still not ready for a Show HN. My work there has also led me to developing some side utilities:
* a library for filesystem tree operations (and other trees, if you're clever enough swapping in components)
* a utility to identify and extract wheels from pip's cache (so that they can be dumped into other installers' caches, for example)
I also hope to return to bbbb soon, if only to make sure that it can build PAPER's wheels smoothly (and with a few other basic conveniences implemented).
Oh, and I wrote an article for LWN recently and have plans for a few more....
