Ask HN: What are you working on? (November 2026)

What are you working on? What have you been curious about lately?

As a heavy LLM user in my daily work, I've been working on optimizing agent memory on complex projects. That resulted in this simple Rust-based tool called Wayfinder: https://github.com/zaterka/wayfinder

I've been trying to improve agent knowledge over a codebase, and existing approaches weren't giving the result I wanted, and I wanted to keep it simple. In the end, I added a semantic layer on top of an LLM Wiki and it saved 30% of token usage in multiple benchmarks I ran. It also adds some nice features to deal with concurring agents updating the shared memory, to ensure all information there is reliable and fresh.

It's published to PyPi, so an "uv tool install wayfinder-memory" already does all the work, and it's compatible with almost all Harnesses.

Working on a Chrome (& Firefox) extension to make finding and downloading Free DLs on Soundcloud easier.

https://cratediggr.com/

Artists make users jump through hoops to like, comment, repost etc.. before giving them access to the download - CrateDiggr highlights the free downloads in the Soundcloud UI and clicks through the download gates for users.

Been a fun passion project, check it out if you download tracks from Soundcloud!

I'm working on 3 products now:

1. FormBeep(https://formbeep.com) at $38 MRR now - A form to Whatsapp tool. Stack is mainly CF workers with Clerk Auth.

2. SlashLink(https://slashlink.app) $0 - A simple pay as you go amazon link localizer. Great for affiliate folks and a cheaper alternative to Genius. Stack is same, CF workers with SQLite(D1)

3. StackStats(https://stackstats.app) $791 - A better advanced analytics app for Substack writers, fully local. I have been writing on Substack for a while now and their analytics suck!

Still plugging away on Flopper to build a holistic view of the GPU market including providers, rental prices, vendor information and mostly - specs for GPUs.

Added a way to look at power/flops and new model requirements lately to try and estimate how many GPUs you need to run a certain model: https://flopper.io/tools/llm-gpu-calculator?model=llama-3-3-...

We've been reverse engineering the tensor core on TPU v5: https://gherkinlabs.com/v5e-tensorcore-instructions

The work mainly stems from a belief that Nvidia gpus' architecture are a bit subpar for machine learning and that tpu could be a viable alternative but are still rather undocumented.

https://skymap.rulkens.com A browser based open source universe explorer. I'm in between jobs currently and finally took time to work on my passion project. It started with just visualizing some galaxy surveys, but it got a little out of hand and now includes everything from hi-res tiled earth/mars, Gaia star field (16M stars), a milky way renderer and much more.

It's so amazing to have the ability to gather and parse publicly available scientific data and actually visualize it in real-time. It's one of those projects I'm learning a lot from and can keep going with (the universe is a big place :)). As a software developer for 20+ years, its been mind-blowing and often also frustrating to have Claude generate code that I deem good enough. About half of my time has actually been spent on refactoring, building quite some skills in guiding LLMs in the process. I guess that part still hasn't changed in a growing codebase.

Still working on Kavla, my open source SQL canvas https://github.com/aleda145/kavla

I'm very excited by adding interactivity. I have a new "knob" feature that pops out when you type {var}. It infers the column's type and values.

`SELECT * FROM hn_posts WHERE score>{score}` will grant you a slider that goes from 0 to 6015

Titanic Browser demo (no login, it's all WASM): https://app.kavla.dev/

Also been working on a "chat to data ingestion pipeline". Not sure where I'm going with this but I like the idea? https://github.com/aleda145/pompos

I've been working on a voxel game engine called Bonsai for ~10 years.

Probably the most interesting thing about it at the moment is the editor. The world, and most things in it, are represented as collections of SDFs. More accurately, they're density fields, but, potato-tomato. The world generator and editor operate almost entirely on the GPU. I've been writing a graph compiler similar in spirit to compilers that execute LLMs, with some key differences. The SDF 'program' gets jitted into a kind of bytecode and fed through an interpreter in the world gen shader. This way, the world gen and edits can be applied deterministically using one big fused program, and transferred back to CPU land using the async PCIe hardware. I get something on the order of ~99% ALU residency, 95% L2 hit rate and 20-40% vram bandwidth usage.

Compared to doing world gen on the CPU, it's so fast it feels like magic. It's taken me the better part of two years to get this working well.

One neat thing about representing the world as SDFs is they've been thoroughly researched and documented by a guy named Inigo Quilez, and they have a lot of nice mathematical properties. For example, you can do a smooth union of arbitrary SDFs to get nice rounded contours where shapes join.

I'll do some shameless self-promotion and leave some links here for anyone interested in looking at the engine, language code, or some pretty pictures.

That's so cool, building something consistently for 10 years is no small feat. How did AI helped you, or How did AI impacted your day to day work in recent years ?

Thank you :) One of the nice things about working on a game engine is it's actually a large collection of small projects disguised a big one. That let's my squirrel-brain jump from thing to thing and have enough variety to not get bored.

I just started using AI a few months ago. My smoke-test was "can it write a simple memory allocator". Until recently, every time I tried to get an AI to write an arena or simple buddy-style heap allocator, they just vomited all over themselves. To my surprise, the last time I tried, the AI absolutely crushed it; it unearthed tricks I didn't even know about in one shot. Since then, I've been using AIs to do the boring, rote work that effectively just boils down to me typing in something that's in my head. For that, they're great. I typically sketch out the thing I want it to make, then tell it to fill in the blanks. Sometimes they still go off the rails, but all in all it's a useful tool.

Where I've found they still struggle is making any architectural decisions, or where performance matters.. even a little bit. They often make super braindead decisions when it comes to performance for no discernable reason. They'll course correct when you tell them to, but I've had to keep a close eye on the output and reign it in frequently. Asking an AI to design a system from the API level hasn't ever returned a good result for me.. I always do that work.

All in all, I feel like using AI will probably make me a better programmer in the long run, contrary to popular belief. They accelerate the boring stuff I already know how to do, which leaves me with more time to work on the edge of my skill level where I grow as an engineer. Guess we'll see in 5 years.

I've been using the recent MIT weight-space programming techniques to work with neural quantum states, which are neural networks that represent a quantum wavefunction. I was able to produce a bunch of novel networks for a few hundred dollars of cloud GPU, which would have probably cost tens of thousands to train in the traditional manner.

https://paulg.info/2026/11/04/quantum-weight-space/

I try to 'vibe code' a product every 2 weeks. Most of them go unpublished, I just build it for the sake of building it. Most recent project is Unmute Party (https://unmuteparty.com) - multiplayer party games for remote teams, played in the browser during a Zoom or Teams call. The server is EU-only for now, and I plan to add US servers next week. Most of it is free, the paid tiers aren't even working yet. The paid tiers can be unlocked by using code HNWHATAREYOUWORKINGON.

Apart from that, running a travel agency I'd never be able to without agents (they manage my ads, social media, website content etc.). Started with boa.ba and it went quite well, now preparing dobosnia.com

https://www.haptrix.com - An editor for Core Haptics, with the release of the iPhone Duo, the editor finally makes sense on device, so I've been working on the new UI.

Still changing along on Incredible (https://www.incredible.rs/)

A New, Experimental, Modular, Declarative, Event Driven and Reactive. It builds cross-platform apps that can be compiled for the terminal (macOs, Windows, Linux), a standalone native window (macOS & Windows 11), or the browser (via WASM) from one unified code base.

Curious if this project will ever be 90% done.. ;)

I built a new abstraction layer for code (https:// www.archme.io), as I believe it's no longer the right medium for understanding and collaboration in the era of AI and 10k LOC PRs.

It scans your codebase, turns it into permanent c4 & sequence diagrams and keeps them up to date on each commit. Then, instead of reviewing a 10k line coding PR, you review a 30 line change to sequence and C4 diagrams.

npm i -g @archme/cli && archme init to run it on your own computer, code never leaves your machine.

Launched a word logic puzzle game called Meshword: https://meshword.org

It combines nonograms with crosswords, requiring both logic and word knowledge to solve. I am still working on the interface and tutorial, as well as the puzzle difficulty levels.

https://asm.build - the package manager for assembly projects.

the plot: Programming languages existed as an abstraction for humans. As writing code becomes cheaper, we can write it for each architecture as long as the specification is done well. The costs of running will matter more in relation. So don’t make your AI write rust, but assembly

HostsTray, tray utility to manage your hosts file, that also has a reverse HTTPS proxy builtin, that installs a self-signed CA and generates certs on-the-fly.

https://github.com/maxmart/hoststray

Also it forces your browser to "flush" their DNS by killing the keep-alive connections that for example Chrome keeps open in background. And it can be controlled by your local coding agent through a simple API (which also serves the skill for it)

My integrated terminal + file browser with enhanced autocomplete and search. Replaces all native OS ones for me: https://github.com/David-OConnor/peregrine . Also includes misc utility OS functionality, tailored. (Advanced clipboard, a scratchpad etc)

A proportional width font terminal. "i" and "w" shouldn't take up the same amount of horizontal space. We used to have to do that because computers were slow and we counted cycles and every bits mattered. We live in a land of plenty now though so we can spend cycles doing math so that ls -l/top/etc table output is still aligned but "i" and "w" can take up the appropriate amount of horizontal space.

I'm building an open-source "spatial workspace for directing AI coding agents like an engineering director".

I got overwhelmed by walls of text of parallel Claude Code sessions. This limited the sessions I could steer in parallel to maybe 5 or 6. I knew there had to be a better way, and I found one: A canvas per project. Work laid out as cards. An agent in a worktree per card. Chat condensed to WhatsApp-style back and forth, not a litany of tool calls. Result is usually a narrated demo video that I can comment on by voice to have the agent go another round. Remote-control from my phone. Remote workers to scale beyond my machine. Everyone I know who tried it has stuck with it so far.

https://github.com/sadilek/obeya

cool! I will try it

Noticed how well Claude works for transcribing old German cursive, especially for broad hits in non-indexed 17th century parish records. Motivated me to pick up Ancestry again and helped me quite a bit in following some lines further back.

Then also HNowledge[1], a free iOS app for browsing the HN stories and comments I've upvoted. Made it to fit the way I browse HN, which is upvoting mainly what I find interesting and may want to come back to. The app lets you browse by date, domain or score, add notes and export. Apart from syncing your upvotes from HN, everything stays local without any tracking.

Wanes[2], an Apple Health logging interface for tracking how long symptoms last. I tend to have headaches quite often and the way Apple lets you enter that data is pretty limited, so I created an app which starts a Live Activity for one or more symptoms using widgets, Control Center or Siri. You can change the severity rating while it runs and stop it from wherever you are on your phone (Home Screen, Lock Screen, Dynamic Island, Siri).

I’m still working on https://feedsync.net, a tool to push RSS feed updates to Discord.

It’s been getting a decent number of sign ups despite me not really posting it anywhere or doing any marketing.

Ultimately a fun project, and useful for myself and a few friends, so I’m happy others are even interested in trying it.

I’ve started to regret using Phoenix LiveView, as it’s only deployed in one region, so high latency far from there. I’m exploring a SPA as a better alternative.

Otherwise, I’ve been playing around with a Lua engine to build feeds for websites that don’t support them, using AI to build the Lua as a once-off. It works reasonably well, but isn’t ready for prime time just yet.

A complete implementation of React in Godot:

https://react.breaka.club

Because I can. Well, let's be honest: because LLMs can. There's nothing particularly novel about this. It's just wiring a bunch of libraries together. Certainly would have been time consuming, but not difficult, strictly speaking, since all the heavy lifting is done by the libraries utilised.

Likely going to migrate https://breaka.club HUDs and editor UI to React since Godot control nodes are by no means impossible to work with, but somewhat cumbersome.

EDIT: Oh, will be open source like a lot for Breaka Club's other libraries very soon. Still optimising.

I’ve been working since the start of the year on a minimalist web reader (https://papercove.app) that I use every day to follow RSS feeds, newsletters and read-later, and that helps keep things from piling up.

I thought I’d get where I wanted much faster, but it turns out I ran into quite a few challenges: it’s quick to build something simple, but it takes much longer to get a reader that’s robust and pleasant to use (extraction, parsing, security, infrastructure, etc.).

On the tech side, I’m using my usual stack, Laravel and Livewire, with some Python for extraction and Go for the email infrastructure. This month I’m working on the beta release, since several people around me were already using it, so I’d like to gather more feedback.

That is a great landing page! I can relate on the velocity side, it can be quick to build a feature, but it takes time to get everything feeling right and usable.

For the first time in along while, I'm not actually working on anything. I do some vibe coding for fun.

I'm kinda leaning towards vibe coding my own GUI coding agent. I currently use Pi and recently have been playing with Herdr and Paseo, but none of these feels right to me. These are amazing tools, but ai think we could do better. But I'm very hesitant - I know the only way to "succeed" in a project like this is to write (vibe code) hundreds of thousands of lines of code and it's kinda depressing.

Getting https://streamish.github.io/ ready to launch, a music server compatible with multiple 3rd party mobile apps and particularly Synology and QNAP. Want to do Plex next but I suspect that's a dead-end since I think you can't directly sign in you have to do it through their website.

Now putting it to personal use and keeping an eye out for issues and rough bits to smooth over.

Built with -

NestJS, Sequelize + SQLite, OpenAPI, and Jest

React, TanStack, Shadcn, and Playwright

A suite of high-dopamine games which use smart exercise bikes as the control interface.

When playing Zwift, Rouvy, etc, I find that I get too competitive and ruin longer workouts by trying to keep up with or sprint past people who are much faster than me over long distances.

This is bad for building stamina and endurance, but I get bored, and it's hard to fight boredom and physical strain both at once.

I do not get bored sitting in front of Balatro, Raccoin, Tetris - anything with bright colours and satisfying noises and combos.

The first finished prototype game is very simple: you sort coloured marbles. Higher watt output from the bike means marbles are blown, by wind, upwards as they roll across the screen. Lower watt output means they fall. Steady watt output means they move horizontally. Marble goes into correct hole -> satisfying noise. It rewards steady watt output over time, with minor adjustments, which is what I'm trying to work on right now.

I was pretty amazed by how engaging I found it (total iPad baby brain). The miles really fly by - I get tired before I get bored.

I think that next I'll either do a tower defence game, or a less-dopamine-rewarding game in the style of Kerbal Space Program. Taking your actual weight and watt output, putting a bike with wings into a physics engine, and the gameplay loop being unlocking increasingly large airplane pieces, and designing - then flying - increasingly ridiculous airborne bicycles seems like a compelling idea, though less good for fitness.

The control surface being so limited - essentially one measurement which can either go up or down - is a really fun constraint for creativity.

There's something in this idea. you can actually tie it to a smart watch (Amazfit allow for custom apps trivially for such uses), and you have a bigger pool.

Thanks, yes, I agree - it really doesn't "feel like" exercise when you're being bombarded by dopamine rewards. Despite this, most "exercise games" leave me with the same feeling of boredom / "fake fun" I got from playing educational games on the computers in the IT room at school.

I'd love to try a similar approach to gamifying exercise on a smart watch. That's an even more fun problem, because (when running, for example) you don't even have a constantly-present screen to communicate dopamine to the player with. Perhaps some watches wouldn't even be able to provide sound feedback? I've never owned one. It's a really interesting constraint for game design.

Do you know the youtuber who play elder ring by physical control of his body a la motion capture? https://m.youtube.com/watch?v=L2VMyd4QbyE

I didn’t - that’s crazy. Looks good for a workout. Thanks for sharing!

A modern take on the game FTL: Faster Than Light, with inventory autobattler gameplay. It is called Cosmo Cargo and a demo is available on Steam: https://store.steampowered.com/app/4659480/Cosmo_Cargo_Demo/

Playing with 6502 assembly.

I have a PAL-2 [1] (a modern KIM-1 re-creation) and started learning 6502 by entering programs from The First Book of KIM [2].

I wanted to be able to compile/link the assembly from the book so leaned on Claude to set up a 6502 dev environment for my Mac. I put everything needed (and instructions) on GitHub [3].

(Claude also has been helpful in re-formatting the 6502 code from The First Book of KIM into a more modern style compatible with modern assemblers. A few of these modernized programs I added to the GitHub repo above.)

As it happens, I am also fixing/formatting The First Book of KIM by recreating it in a modern page-layout app (Affinity Publisher). The PDF scans that are out there are not pretty, have OCR errors (and the book itself has mistakes). Hopefully I'll have a new version of the book/PDF out on the internet by the year's end.

Started making youtube videos again, using my human brain to pick the topics and write the scripts, and AI to edit them (mostly).

Here's one about speculative decoding (and how it speeds up AI inference): https://www.youtube.com/watch?v=cGnIKjGIwjA

Repair of a Collins 651S-1 receiver. The 65-95 mhz vco module is bad, but if you over damp the pll loop filter it does eventually lock and receive properly. I found a similar but not identical replacement from a different model receiver. It lacks one of the two DC tracking signal outputs but I added an op amp based circuit to simulate the missing signal.

The loop is stable and responsive when receiving from 17 to 29.9999 Mhz, but not much below that... Almost got it

I'm still working on making JustFax Online[1] more profitable. Added a bunch of features recently, as well as invisible improvements in fax routing, and admin stuff for myself to better analyze the traffic and patterns.

Other than this, I'm playing with vibe-coding stuff I always wanted to do but never had the time/skills to do. For example, I built a TUI on top of beancount that is tailored to my needs and my business[2]. I also completely got rid of self-hosted plausible and umami analytics, and replaced them with vibe-coded built-in-rust (c) analytics tool that relies on both js-beacon and streaming of caddy access.log. Will probably publish about it in my blog soon, so subscribe to the RSS if you want.

Lastly, I'm messing with self-hosting. I completely ditched Github and Gitlab for self hosted forgejo + actions runner. I set up proper backup plan for everything I care (documents, immich library, my SaaS DB, and the forgejo repositories).

I’m making a digital real watercolor kit.

I’m a software developer and watercolor painter so my goal is to use real world painting techniques and have the results feel and look real.

Modeling the physics of paper, brush bristles, pigments, water, color mixing, drying in real time using gpu.

Built in rust using wgpu.

Currently looking for iPad beta testers if anyone is interested (supports Apple Pencil or finger).

My new favourite shader running realtime over your camera input. Has gotten great feedback from kids as well :)

Knowers of plasma pong might see slight resemblance.

Working on / dog fooding my graph based recipe app[0].

There are more things I'd like to do with the graph concept, like linking two user's recipe trees if they were imported via the same URL. Really trying to to avoid features that I think would be cool that don't provide any functionality.

There are still a few features I'd like to implement that are more in the vein of nice to have in any recipe application, like nested recipes, temperature conversions, volumetric ingredients amounts to mass conversions, etc.

But I've been using it for new recipes and converting my old recipes I have written down in the margins to this format and I've been happy with how usable its been in these early stages.

been curious about the intersection between observability, SDKs, and product analytics. i couldn't find anything around SDK observability so built this little tool. curious what yall think!

i assume at bigger orgs there is some internal handrolled tool like this that ingests datadog/sentry/whatever info...if anyone plays around in this space and has feedback id love it!

A mobile car racing game with novel, one-handed controls: https://awais.io/simracer

Lipik, a free open-source dictation app for Mac (https://github.com/Gourav2609/lipik). Hold fn, talk, let go, and clean text lands in any app: ums and self-corrections removed, spoken punctuation turned into real punctuation. Speech-to-text and clean-up both run on the Mac. On my 106 English test clips, lines that came out fully right went from 28% to 76% with clean-up on. Right now I'm working on Hinglish (Hindi + English in Roman letters). It gets 7 of 20 test lines fully right, so there's a long way to go.

https://www.abejora.com - time tracking for freelancers and small teams

Lately we've been working on access for AI agents. A lot of people want their own agent to do the repetitive part of time tracking. Control remains important, which is why we rebuilt our core this month to support change history and full undo/redo functionality. Feel free to try it with your own agent.

We built this after the timesheet tool we paid for raised its prices and moved some features that we used regularly behind more expensive plans. We had to add three new colleagues, and everything combined this would cost us $500 a year more for the same software.

We run Elixir and Phoenix LiveView on a Kubernetes cluster made of Talos instances.

We're still looking for feedback on the product, so please let us know what you think!

I'm working on Eigakan Guide (https://eigakanguide.jp/en), a cinema showtime aggregator for Japan. Every popular cinema site in Japan only allows for very few filters, making it hard to find exactly what I was looking for. So instead I built a site where it's possible to filter by area, cinema, date, time, features like IMAX, English audio, English subtitles, and more. This allows for searching for stuff like IMAX showtimes with English audio on Friday after 7PM.

Since the last time I posted on HN I've added 100s of cinemas, user features like being able to save search filters, movies, and specific showtimes. Also a ChatGPT plugin which allows for searching for movie showtimes using natural language directly inside of ChatGPT (https://chatgpt.com/plugins/plugin_asdk_app_6abfdc298c208191...).

Finally I've added AI search to the site as well, allowing for natural language search with queries like "English audio showtimes near Shinjuku tomorrow" and so on.

I would really appreciate feedback for things to add, things that are hard to understand, and anything else!

Few apps I have originally mainly done for myself; Vaava (https://vaava.app) , been tweaking the e2ee data sync between connected apps, and the webrtc based baby monitor feature stability. Crazy how easily Astra / opus 55 level models create quite complex ad-hoc reproducible (almost automatable) test scenarios with 2 phones, laptop and other tools / peripherals they know they can use, for example for the baby monitor feature Astra did a setup for me which i can reproduce to test that the video + audio works fine between 2 phones for x time.

Also trying to replace own Duolingo usage with Fika Lingo (https://fikalingo.com) basic idea was to first repro the practice of matching words. There is now few other types of language / vocabulary practices. The practice generation works on-device with local LLM, you can give the topic yourself like "Words that relate to Hacker News". Downside at the moment is that English needs to be the counterpart of the practices. Cant guarantee good enough quality with something like germany <-> italy practices. I'm trying to do finetuning with LFM models to see if it would be feasible to improve the local practice generation.

Working on ZShot [1]. I'm about a year in on a local-only browser tuned specifically for CLI and API usage - kinda filling the gap for "geez, I sure wish I had a browser, but not one to look at". You need a webpage as PNG, or an MP4, or a website as a WACZ or SQLite database. There's a Mac app to help with discoverability of options, but I wanted for my local tooling and building services on top of it.

Along the way I ended up adding an internal agent framework to satisfy stuff like "log in, click the button, and then take a screenshot", out of which fell stuff like automatically generating Playwright tests from that. It even runs the Playwright test suite and Puppeteer test suites ( a bit faster, and for a lot less memory ). I kinda love this bit because I can layer in multiple models that will bounce control of the web session between each other, to do stuff like let a Typesafe model choose to escalate to Opus when it needs higher minded behavior. It's fun to watch it happen.

I've mentioned it a few times around here, I'll probably do a Show HN soon when I feel like it's ready for that. Hopefully soon.

An opensource personal expense tracker, I was a happy user from an offline expense tracker which wiped my data when playstore decided auto-updating it,

I'm at the point where I'm finally actively using it to register my activity, it is straightforward to register tickets by sending them to a telegram bot, then, reconcile those by uploading my bank statement.

I'm trying to get the lowest possible usage friction so that I keep using it.

So far the better built pieces related to the data ingestion. Once this is good enough I'll build reports + anything coming to my head as a useful piece.

I'm leveraging AWS textract + bedrock + bda to parse bank statements. I expected this would have been easier but it is still a very complex problem which had required me to put many iterations (so far it works nicely with my own statements)

For ticket parsing, AWS textract + parsing rules has been enough.

I wrote a bit more on my blog https://alexitc.com/blog/2026-10-16-opensourcing-my-expense-...

Outside of my day job, I've been working on:

- hermitator, a tool to run multiple isolated AI agents for WhatsApp on a single machine, with idle agents using no RAM: https://www.encona.com/posts/hermitator/

- showntell, which allows your coding agent to explain things to you with a video that starts playing within a few seconds of you asking: https://www.encona.com/posts/showntell/

- a philosophy tutor (testing in private for now) that does 2:1 live philosophy lessons, each exploring a single topic (aimed at ~10yo kids). I've tested this successfully (i.e. two kids did an hour and they want to do it again), and am trying to make improvements.

- some other education-related things

- a jmail-style mailbox viewer: https://www.encona.com/posts/mailbox-viewer/

Oh, showntell is nice! I'll try incorporating it into my project (obeya.si), which already uses demo videos to show me work it did. But when I ask a question, the response is still just text. Could be so much better with your solution.

For the past two years I've been working on my day planner app Ember.

Most planners treat your schedule as fixed, so the moment a meeting runs long or a task takes twice as long, the plan is wrong and you either fix it by hand or give up on it. In Ember, if you move a task or change how long it takes, everything after it shifts later, and it flows around fixed things like meetings. It's been super helpful and I have been adding new features ever since.

Right now I'm working on a native Kotlin app to replace the current one is web + Capacitor and exploring full duplex voice models so I can add or move things around the app while having a conversation with an agent.

Launched Diligly today. Investor-ready data rooms for startups.

A networking-over-DNS client and server, in Go. https://sr.ht/~nullenenenen/ShrewDNS/

A bit like iodine in the basic idea, but the execution and network topologies you build with it are different. It's more of a building block; you get your DNS channels represented as UDP endpoints, and take it from there, ie you can run Wireguard over it, or SSH or a SOCKS5 proxy (using quicmux, so over QUIC), or run Mosh straight over DNS if you're crafty.

It has an Android app too! I tried to submit it to F-Droid but they're so swamped in spammy or low-quality apps that they're not taking any brand new apps :-( A sad state of affairs, that.

A small team and I are working on Sendery [1], a transactional email platform for product teams. We're trying to fix some of the headaches that come with managing product emails as companies scale: keeping track of hundreds of templates, maintaining consistent designs, coordinating changes between developers and marketing/ops, and managing everything across multiple languages is way more time consuming than it should be.

It's been a fun project to work on since it's been a pain point for myself on many projects, so I'm mostly just trying to solve my own set of problems and hoping other people find it useful too.

I've been working on a planner for the past 2 years for people whose day never goes the way they planned it.

I was trying to solve the problem I had with time-blocking, where your day ends up derailed and you give up on it because it takes too long to replan. I have solved with the idea of a cascading calendar. If I move a task down or change its duration it pushes other tasks later in the day.

Since then its kinda grown into my full productivity system for logging my thoughts and planning and documenting my life

I am currently on maternity leave with my first baby have just launched to the app store my first app!

I'm a product designer by trade and learnt to vibe code on Claude about a month ago now. I was weaning my baby and he developed a rash and haven't been able to work out what the pattern was causing it. So I created an app for weaning parents to log the food, add any reactions so when talking to their GP they can start to see a pattern and all advice, like nutrients, food variety, how to serve food all coming from the NHS and FSA.

Currently got 12 mums using the app and would love any feedback to make it even better! <3

I'm working on an iPhone app called PhotoGather. https://apps.apple.com/us/app/photogather/id6738232616

I've got 40k+ photos on my iphone, and wanted a better way to interact with them. The basic idea I had was to virtually stitch all the photos together into a gigapixel image, and navigate that image with pinch and zoom. On import, the app hierarchically groups photos based on date and similarity. The user can go back and edit the groups, change the layout, and adjust the size of photos if they choose.

The interesting I noticed is that in the process of curating and organizing my photos, I stumble across memories and moments that I had completely forgot.

Development Challenge: The app does two interesting things underneath the hood... First, given an arbitrary number of thumbnails with different aspect ratios, it finds the best sized rectangle that completely fits all the photos. This allows me to recursively stitch groups together and always output a rectangular thumbnail for the group. Second, the pinch/zoom UI uses these nested thumbnails directly without slicing/dicing to fixed sized tiles.

1-year part-time experiment: can you build a large project with AI writing the code and AI plus deterministic tools verifying/guiding/enforcing it for structural and behavior consistency, without a human reading the code?

I'm building a polyglot web framework in 15 languages, with C# and Lean4 as the reference implementations. Structural and behavioral audits using deterministic tools check that every port stays consistent with the reference. It's about 1.8M lines now. I have not reviewed the code/neither have i verified the behavior tests except at the time of giving requirement and never seen some of the language code at all.

The question is how far can we produce "working code → correct code [Possible] → good code [Unknown]" with deterministic audits correcting structure, ai mistakes and behavior validation.

So far the quality looks acceptable with lots of correction of AI output done without looking, but it isn't fully verified.

I’ve been working on Beacon, which just got Beacon approved on the App Store! It’s a mobile app to instantly answer “which friend is free to talk right now?” and summon them in a single tap.

Send your beacon to a group, and everyone gets a gentle ping. The first person who answers gets connected for a 1-1 call, and for everyone else the signal drops silently. It does not log any missed calls so there’s neither pressure to answer nor pressure to return calls.

Overall it works really well! It’s best if you're able to join with 4+ friends/family you’d like to chat with more. I have dozens of connections in the app now and it feels like absolute magic to me. I tap the button to send my beacon to everyone and get a random friend on the line.

I wrote a children’s story in Galician about open source. It's told as a fable. I made it open source, and people are now helping translate it into Spanish and English.

I’m looking for ways to fund printing and distribute the book. If anyone has done something similar, I’d love to learn from your experience!

Magic AI - I'm using it as a sanitized kids chatgpt for 7 activities: Story, image creation, chat, reflections, journal, learn and quizzes. Sends me daily summary on Whatsapp.

It started with building pi in the cloud - with pure cloud flare workers. I have it working now, and can spin up - the wrangler agent can fully run it as long as you pass it an inference key, including a file view, a chatgpt like experience, and ability to build and host custom apps. Can use alarms to wake up to do plain language tasks, etc.

Trying to figure out how to package this up, and where this would even be useful for other apps.

For now Im working on an agent-orchestration application that is taking tickets from a tracker and giving them to an Agent. It's called Even Keel.

The main feature is, that I can use different subscriptions/API keys (Claude and Codex - v0.1.4) and trackers (GitHub, Linear and Huly - v0.1.4) to make Even Keel start an agent for every single issue, task by task, one at a time per folder. There is also a parallel feature, so I can run more than 1 project at a time.

Once upon a time, when codex agent was integrated into the app, I wrote a ticket to make codex his own hook. It reused a hook that blocked its own git merge, if tests did not pass. I started calling it "A new agent writes its own cage"... Right after, it turned out it doesn't listen to the hook and it fixed it

Version 0.1.4 is already shipped, but v0.2 is coming soon with more supported trackers, agents and new features.

https://robheffern.palaich.net/sports/

I like sports! I like data! Combine!

This lets you see what the games on today are most similar to in the history of the sport. Click into one and see.

Also, the Sports Zodiac.

Like farmers of the olden years and the stars, we kinda set our clocks by sports these days. But what does that look like?

'Play the Years' to see a good timeline of how the years go by.

The war years, the lockouts, and the pandemic are just really easy to see in the data and quite stunning really

How to make data storage on multiple storage devices unbreakable and consistent? The former means for me that back-ups should be automatical and serverless, the latter means that no matter how much of that HDD/SDD devices are connected, I want always to know all metadata of all files I have. I want this software under GPLv3 if to consider GPL still protects me from anything because permissive licenses are no better than WTFPL by any single case.

My first idea is to require the user to have more than one disk for the system needs and the system should know all of the rest data devices user owns. My second idea is to treat different files as having different priority which impose multiple copies. My third idea is to make the software accessible, and the last idea is to make encrypting of all the devices easy and with no ties to any commertial entities. I would like to have a discussion about how to not lose anything digital.

I've been building out a link blog idea called Linked List that I've wanted for a long time. Curation will be even more important in the future and I would love to have another option beyond Hacker News and Lobsters to find good reads suggested by fellow humans. It has been a fun space to explore ideas.

Not quite ready to open up sign-ups, but you can get an idea of the site here: https://linkedl.ist/@kale

Built an app to suggest best local beach for given weather for my town. My partner shared with local moms and they seem to be loving it - https://beach.metacursion.com/

Also revived old project - https://aminosplore.metacursion.com - the idea was to compare what essential amino acids each food contains using spider web chart. It’s been dead for a while due to USDA API changes so I revived, added macros and enabled to build foods into actual recipes.

Finally have been improving elsrc.com - an easy and scalable way to use ai image generators. If you need hundreds of images you can just request them by url. Supports versioning, batching, regional and national styling based on viewers IP and few other neat features!

I am building a system that connects texts (books, research papers, etc.) in a meaningful way to help people decide what to read and be aware of how texts relate to each other.

This sounds like a really cool project, do you have a repo or anything?

Not yet, but I am planning on making it open-source later.

I am building Abbox trying to help engineers focus longer on tasks without being interrupted by non-technical people with small requests.

I always got annoyed by change this h1 to h2, add tracking to share button, why can’t the customer play the video, the styles don’t match figma.

If you are engineer who also gets distracted I would love to hear your opinion and feedback. It is a bit hard to put it all together as every department has his own needs and opinion about the website.

Two main side projects lately:

Thesoapbox.email - a social experiment email lottery to see what people do when suddenly given enormous reach. Every day a new subscriber is drawn to email the whole list. It’s hit 10,000 views in a couple of weeks which is my most viral project so far.

The second - a personal AI learning platform built on recursive self improvement and tailored content to push my boundaries. I’m a lifelong learner and this unifies everything for me. (Currently not public)

I've been working on an Obsidian plugin to quickly enter caloric and nutritional data (https://www.github.com/Krishna-Sivakumar/joule). The core features are done (A DSL and a runtime for finding and resolving formulae recursively), and I need to work on documentation and some convenience features. Hoping to finish it this month!

Maintaining my indie social network for tech people https://stackness.dev/ (currently struggling to keep users on the platform, even games and achievements didn't help, can you believe that? :D)

and this weekend I'll finally launch a tool for guitarists and their friends https://kantamigo.com/

I just got Beacon approved for the Apple App Store, it’s a mobile app for answering “which friend is free to talk right now?”

It’s a one-to-many phone call that only one person can answer. Send a beacon to a group, and everyone gets pinged at the same time. The first person who answers gets connected for a 1-1 call, and for everyone else the signal drops silently. It does not log any missed calls so there’s neither pressure to answer nor pressure to return calls.

Overall it works really well! It works best if you're able to join with at 4+ friends/family you’d like to chat with more. I have dozens of connections in the app now and it feels like magic to me. I press the button and get a random friend!

I'm working on a cross-file deterministic drift checker https://github.com/mennanov/blockwatch

The idea is that the source code is annotated with special rules which configure how parts of the code (also configs and docs) depend on each other. This can be done either directly in the source code comments or in a config file blockwatch.toml

This tool is very useful for large codebases that e.g. share constants across programming languages and configs, have docs that should strictly reflect the current state of the code, etc

It uses tree-sitter to parse the source code, 35+ languages are supported.

The project is actively developed, your feedback is welcomed! Thanks!

Currently working on adding support for iPhone Duo to my hacker news app Hack. The app has been around for 9 years and when I made it, the menu bars and navigation buttons were custom views. That doesn't seem to work well for iPhone duo due to its vertical stack menu on the right side. So, I've been switching over to iOS native navigation bars and menu bars along with a bunch of other improvements. I was hoping to have it done couple weeks ago but I had to leave country for a family emergency. So I am working on it this week. It's mostly done, I'm just doing some final testing now and will submit to Apple this week:

Honestly? Still just trying to get hired.

But apart from that, I just updated my website's theme to something I wanted to do for quite a while now – a fantasy desktop! If you'd like to check it out: https://0xff.nu

I'm also trying to just learn new things with the time I was refunded by being unemployed.

I keep saving blogs and articles but almost never revisit them. So I’m building an Android app designed to help me actually read what I save. You only get one saved article per day. Finish today’s read to unlock the next one. You can also save Twitter, Reddit, etc. posts separately and revisit them anytime.

Right now I’m mainly validating whether people would actually want something like this. If there’s enough interest, I’ll run a small closed beta for Android.

Join the waitlist for beta access: https://forms.gle/XWXmK8HUSmAtfms29

TO be honest, I dont think I will pay for this, though revenue can still come through Ads

I've been working on trying to be more helpful around the house, and trying to spend more time with my kids. I'm trying to give my partner a little bit of relief so that they can pursue their passions as well.

An Obsidian plugin that turns handwritten reMarkable notes into searchable text. You can run the handwriting recognition locally on a Mac. The latest feature I added sends your highlights and margin notes from the tablet to Readwise. https://taggedsync.com

I'm working on a simple way for AI's to talk to each other: https://counterparts.ai/phone

So far it's helpful for messages between my own AI's (chatgpt and claude etc), and for having my AI trade tech tips with a friend's AI or talk to my wife's AI. My AI also got its first message from a strangers AI from france which has also been really interesting. I read all messages first and approve before sending anything, but otherwise they're just talking about whatever they want.

I’m building Tinta, a journal app for Android where all the AI runs on the phone. It works in airplane mode once the models are downloaded.

You write or dictate an entry, and a small model (LFM2.5 1.2B) asks you a question to reflect further. It turns out 1.2B models are decent at asking questions, so I leaned into that. An embedding model finds older entries about the same thing and shows bits of them under the new one.

Most people using it are on budget phones running the models on the CPU, where the app provides good experience.

https://tinta.page

Great idea! I'd love this, but as an open source app. Out of interest (not a criticism), what made you decide to do this closed source, especially considering there doesn't seem to be a commercial interest involved (for now)?

Thanks for a good question! I see this app as an MVP that needs user feedback to deliver exceptional value in a world where cloud AI is abundant and doesn't use 2GB+ of RAM to run. I am excited to see what shape it will take, and it feels too early to determine source availability.

Storyline isn't available yet, but about 75% done with it

Hence (https://hencegame.com) is a modern twist on Einstein's puzzle, with fun picture clues instead of text. It's a free online daily puzzle, the same for everyone, where every puzzle is always solvable by pure deduction with no guessing. I launched it October 5. The hardest part was the graphics, making each picture clue unique enough that you recognize it immediately and know what category it's from, even at small sizes. Easier said than done.

Every puzzle is run through a verifier first to make sure it is solvable without any guessing, just by pure logic, so there is always a next step to find, which is what makes it feel so rewarding. There's a hint system to help and it works really well if I do say so myself . No account needed to play.

From what I've been hearing so far, the people who have checked it out are enjoying it and can't wait for tomorrow's puzzle, so that's a good sign. I'd love to hear how the difficulty feels, and whether the pictures read clearly.

I'm vibing an old style RTS game and exploring how far can I get with local models for drawing, 3D models, rigging and sprites. I love how much I can accomplish with Claude in terms of code, but gluing it all together with graphics still requires plenty of "manual" work.

Werkbook (https://werkbook.app), digital forms and photo reports for field crews. I'm a solo Rails dev, and thanks to Claude it now has native iOS and Android apps instead of Hotwire Native web-view wrappers.

Still working away on my book (and library book) recommendations service https://leafle.org

It has if nothing else been very useful for me (it has correctly deduced that I would get something out of borrowing Grief is the Thing With Feathers, the Dispossessed, and Cosmicomics, none of which I would have thought of reading). Plus it has been a fun opportunity to play around with LLMs as an interface and a research and reverse engineering tool; as well as Jev for non-user facing quality work like banning crap openrouter providers based on their output before putting it in front of a user.

Most recently I’ve been dropping off flyers for it at a few local libraries in my area.

I tried it out nd it looks nice!. It’s a great way to support local libraries and bookshops. I hope you have a ton of success!

Thanks! Hope it found you something interesting.

We just got a puppy, and needed a way to track potties to help us with house training. So, with AI/Claude's help, I found a similar open source package (Baby Buddy), forked it, and very quickly made it my own. Self-hosted, local for privacy reasons.

A domain search app called NameTheory: https://apps.apple.com/us/app/nametheory-domain-search/id680...

It uses Apple Intelligence to help brainstorm domain name ideas. I’m interested in seeing what small local models can do as they catch up to larger ones, this is my first iOS app so I started with something simple that scratches my own itch.

My main project is trying not to lose my mind, given all the things I can now create thanks to AI.

Jokes aside (although I'm not entirely joking about my mental health), my main project is https://auradistill.com: First-principles thinking for your AI agents.

It's not just about giving your personal AI agents "memory". It's about encoding memories in a way that can handle ambiguity and contradictions.

That project alone has got me completely hooked on building for and with LLMs.

I've got other projects too, but this is probably the one I've poured the most time and energy into.

Still building the file manager I've always wanted: https://intestinate.com/gusco/

Added an audio player this past month for all fellow file hoarders out there.

Also, you can now choose if you want Gusco to live in your terminal or run as a native-yet-texty app.

Was pleasantly surprised how well turning a Bubble Tea TUI app into a GUI-ish bundle works with Gio UI.

I'm working on Hale, an abstract distributed systems language.

It's a traditional systems language in the sense that you have fine control over how resources are used, but it's abstract in the sense that you have to come to an agreement with the compiler about your intent around the resources, rather than directly declaring the machinery.

It's a distributed language in the sense that there is a higher level structural abstraction in the language that situates computations of the program within a recursive graph structure. Part of that structure incorporates message broker semantics. This gives the compiler a unified view of programs across arbitrary process boundaries. The structural abstractions also enable an effects+formal verification syntax within the language, which allows programmers to codify architectural decisions that are then checked by the compiler.

The compiler itself is infrastructure aware, and the highest layer of functionality it handles is configuring the environment into which applications deploy. The single language handles everything from individual memory allocations to distributed fleet deployments.

The language is close to v1, and I'm currently building a fully distributed inference-as-a-service application with it. Arbitrary hardware/supply matched against arbitrary callers/demand in real time.

https://github.com/hale-lang/hale https://github.com/hale-lang/voice

Currently we are working on Kumoss Open Source, intent-based infrastructure platform that turns natural-language requests into infrastructure changes, while keeping validation, compliance and existing engineering workflows in the loop.

https://github.com/InditexTech/kumoss

Basically allow developers to request any infrastructure need in a web portal and automatically that request is fulfilled following the organization standards the platform team defined.

I've just released v1.0 of Rouler which is VPN split tunneling for windows. Think IP rules for Linux, but with per-app/service connection steering.

I’m still working on https://leafle.org which is a tool for getting more interesting reading (or listening) suggestions that one can borrow from the library (or Libby). I’m done for the moment with building it, so I’ve been doing things like making flyers and leaving them in local libraries.

Been a fun opportunity to play around with ai in various ways - mixed but definitely powerful experience in using it for data research (finding libraries and their locations), very impressive on reverse engineering apis to get book availability. And then a lot of interesting stuff around getting good behaviour from LLMs as chat partners, for example using jev to improve results from using openrouter by getting it to check for common failure modes and ban providers based on their output.

My husband created an AI-powered website, and I've been using it to generate engaging AI videos for social media. This not only helps promote his website (seedeo.ai) but also expands our website's content library, which gives me a great sense of accomplishment.

For the month of November (and starting in October this year) I like to hold weekly cooking challenges to practice and refine my Thanksgiving day feast. Now about 3 weeks out from the final boss level of cooking, and I'm having a week all about brussel sprouts.

I'm building a self-hosted media server for video, like Plex or Jellyfin. I'll be opening the beta in about a month.

Features:

- No paywalls, bandwidth limiting, or crippled behavior. No login required.

- Single go binary, deployed via Docker.

- Reaches your home server from anywhere with no port forwarding, no VPN and no paywall, even behind carrier-grade NAT. No Tailscale required.

- Cast to another device. You can use any logged in device as a playback screen.

- Watch together, with voice support: Play synced video with friends, and also chat voice. You can also mix this with casting to another device.

- Dialogue boost and loudness levelling for every film.

- Real adaptive quality, tuned for a home's upload.

- Hardware transcoding, full quality in every supported browser.

- A library that explains itself: what the scanner saw, why each title matched, guesses marked for you to check, and a disk that's gone missing shown as missing instead of its titles silently vanishing.

- Your data stays yours: The database is a rebuildable index, metadata corrections can be written back as NFO files that Kodi and Jellyfin read, and an automatic backup keeps what can't be re-derived (watch state, preferences, shares).

Security is a primary concern:

With the ever increasing pace of hacks and CVEs and AI-assisted intrusion, you simply can't be too careful anymore.

- The core (which talks to the network, handles the API, users and the database) never opens a media file or runs FFmpeg.

- A separate media node does every file read and every transcode. It has no network access and talks to the core only over Unix sockets.

- FFmpeg runs under Landlock and seccomp with no path to the file and no socket. All it can do is read and write streams.

- Small dependency tree on an allowlist, pure Go with no cgo, secrets sealed at rest and never logged.

- The library can be mounted read-only, so even a full compromise can't encrypt or delete your media.

- Cryptographically signed chain for servers and releases.

Client posts request and masters respond with their offers.

What you think about that guys?

There is already a site here where you say what your job is and garages submit their offers. They can also auto-submit offers if it’s something routine like a standard service.

Hey, Thanks for info. I am from Central Asia, could share a link for that site?

I'm rebuilding a benchtop CNC milling machine.

For years, I struggled to make any headway with Linux - I get so frustrated at how obscure, inscrutable, and unintuitive TUIs are! God I don’t want to waste my life typing esoteric strings of commands into the terminal. When I started with computers that was all there was, and once GUIs happened I never looked back.

Good news though, these days Claude will just do it for me!

I’ve been working on setting up a home media server, using headless Debian on a pi - I’ve got it set up to stream music and videos, hold all my ROMs, I’ve got it automatically standardizing file names and handling tagging and subtitles - all attached to a big 6-drive enclosure that I just stuffed all my random old HDDs into.

Even though I haven’t written more than a dozen lines of code or commands for the whole thing, I am pretty fuckin pleased that now I can just wave a magic wand and say “I want all my video game soundtracks filed under the game name rather than the artist” and Claude uh finds a way to grant my wish. I spend about an hour each night tweaking it and it’s so easy to customize to be exactly what I need.

I am building Esara – the AI hiring platform for candidate sourcing and explainable evaluation.

We’ve just incorporated in Berlin together with two great co-founding colleagues. Honestly never felt more excited.

Though it is a B2B tool, check it out: https://esara.ai

I am working on a Rust-based ext4 driver. The idea is that it can be re-used as a FUSE-based driver as well as (Windows) kernel driver (eventually).

Most of the essential features are implemented so far, but some (mandatory) features are lacking (xattrs support). My goal is to get to a full ext4 implementation that also supports ext2 and ext3 read/write.

The initial motivation was to have a pet project with a use-case for Rust, as I wanted to improve my Rust coding skills, after I did some work on a game server implementation in Rust earlier [1]. My goal is to have an implementation where I have digested every line mentally, which is something that pretty much excludes slop-like use of AI for large scale code generation. And of course I want to really trust the code that touches my files via raw hard disk access. Hence, I use AI mainly for unit tests and (scoped) code rewriting when my code gets too verbose and cumbersome.

In the long run I'd want to add fuzzing to the implementation, so if anyone has experience on this, I'd be interested in getting some pointers.

I "accidentally" created one of the fastest modern JavaScript frameworks out there: https://signy.dev/

...according to my own benchmarks (yeah, I know how that sounds).

Next, I'm planning to submit it to independent third party benchmarks, hoping to find out whether my results are accurate... or not :)

I've also just finished a CSS framework: https://iriscss.com/

Now I'm working on a new backend programming language that runs on the Erlang BEAM, along with a few web applications built using this tech stack.

Building a tool that finds code problems before they become "quick" Friday fixes. Currently teaching it to be less dramatic than the linter :)

Yes, it's on my list to automate these and I even reserved an account for this way back when: https://news.ycombinator.com/user?id=whoisworking.

Will merge the others.

Ur is an (in-progress) universal formatter and linter for every programming language. It's in preview right now, which just means friends are messing around with it and having a good time pointing out all the bugs. Docs are mostly up to date, but buyer beware.

I'm so fucking tired. I built this tool, it's great, I love it, but its full capabilities are too complex to udnerstand. Because of that I struggle with marketing, as everyone is too lazy to try it out. Because of that I get no feedback, nothing to improve, and I can't make the tool any simpler, as otherwise it defeats the magic behind it.

Software is complicated by nature. It's our job to make it easy for the user.

Take a look at FFmpeg as an example. It's a complex tool that can do most things audio/video. A power user can do magical things, but they still provide simple commands for the most basic use-cases like conversion or trimming.

1. Provide sensible defaults 2. Study user journeys and write simple manuals for them. 3. Ask friends or internet communities for feedback.

Don't get discouraged, you can do it!

I've been working on online payment rails for businesses, developers and agents called Tuppence (https://tuppence.ai).

Accept online card payments from just 0.79% (UK) and earn 0.89% on all card spend [1], or get paid out to your bank.

I'm building tuppence to be available in the US, and 20 EU countries.

I'm getting a Point of Sale (POS) manufactured in the UK [2] for those who want to accept payments in person with card readers.

My goal is to help people sell their goods and make a living without paying over the odds for the privilege.

I charge a competitive fee for payment processing, give money back on card spend (with no cashback caps/limits) and do not charge saas fees or lock people into contracts.

Tuppences currently allows people to sell online with a store builder, expense management, payment links, direct debits & bookings - essentially Tuppence is a 'business' layer on top of what you get from the likes of Stripe, Adyen and Checkout.com. There's also have a 'connect' platform, so you can roll this out to your marketplace business.

Next on my roadmap is ticketing and 'treasury'. Treasury i'm personally excited about as you'll be able to earn 4% yield on your earnings, FDIC Insurance (FSCS in the UK), multi-currency banking in fiat balances such as USD, EUR, and GBP, or stablecoin balances like OUSD and USDC, and have bank account numbers to send or receive funds.

It's brand new, i'm still testing payment -> payout flows. These take a little time to verify on live payment rails.

Happy to give some fee-free payment processing for those who reach out and want to be early adopters, I can be reached at ollie@tuppence.ai, or comment on thread.

Tech Stack TLDR:

* TypeScript monorepo covering the API, dashboard, docs, mobile app and SDKs. * The API runs on Ts.ED over Express with TypeORM and Postgres. * Background jobs use pg-boss, so the queue lives in Postgres and there’s no Redis or separate broker. * The dashboard, till and storefront are React + Vite + Tailwind, the docs and help centre are Astro, and the mobile app is React Native/Expo. We ship SDKs for Node, Python, iOS, Android, React Native and WordPress, plus an MCP server and agent tools. * Everything runs on Google Cloud Run and Cloud SQL.

Mostly trying to think about what career to pivot to, since SWE wages are going to get crushed in the next 5-10 years.

Guaranteed weight loss within 2–3 weeks; many people start seeing results within the very first week. 17,000+ members already!

Guaranteed results are achieved using the state of the art adaptive TDEE (total calorie burn of the day) tracking technique we've developed. It's sensorless, so no watch or other wearable is needed. It's way more accurate than those wearables (data included on the website), and our group has 2,000+ members ( https://macrocodex.app/community/ ). You can also read Play Store reviews.

All this completely free, no subscription or ads: https://macrocodex.app/

MacroCodex also works on both Android and iOS and any platform where PWA app can run.

Other other 2 apps are Android only (for now):

If you are looking for a workout app with Alpha Progression or MacroFactor Workout-like “Smart Progression,” or an app where you can run any program like Boostcamp but ad- and subscription-free, check out the Symbiote workout app (beta) https://symbiote-studio.macrocodex.app/

IF you are looking for AI photo Calorie tracking with lots of features which make it very fast to log food on daily basis checkout CalorieCodex (beta): https://caloriecodex.macrocodex.app/

All the apps have been under active development for a few months now.
