Agiler (Serverless WordPress + MariaDB)
Serverless WordPress hosting paired with a serverless MariaDB that requires no plugins or any modifications to customer code. The serverless MariaDB scales to zero, so development sites can cost less than $0.50/month. Also includes MCP and CLI tooling that exposes the infrastructure, WP CLI, and the database so AI agents can develop WordPress sites — debugging, changing pages and posts, etc. — while users can still use the WP admin interface.
Atlas9
A web application framework written in Go.
Raygum
A social site for music listeners, described as 'Letterboxd for music' — lets users catalog, track, and share the music they listen to.
Translucent
An accounting agent factory: a harness and infrastructure for long-running AI agents that process accounting books containing thousands of invoices and transactions.
Makonea personal homepage
A personal homepage (makonea.com) that the author is working on decorating.
Unnamed language project
A language the author is working on; the comment does not specify whether it is a programming language or a human language.
Reportr
An AI client for data analysis that connects to databases via MCP servers and displays large volumes of data, addressing the limitation of using Claude desktop as a database client.
Meli
Meli is a privacy-focused spending tracker for Mac that turns credit card alert emails into spending insights and budgets. It connects read-only to the user's inbox via OAuth (Google and Microsoft) or IMAP, reads only alerts from supported senders, and performs all parsing on the device so financial data stays local instead of in the cloud. It supports seven major US banks (AMEX, Capital One, Chase, Citi, Discover, Bank of America, and Wells Fargo) plus PayPal and Venmo.
Notekpr
A local-first, end-to-end encrypted note-taking app positioned as an alternative to Notion and Obsidian.
smolvm
A replacement for Docker focused on better isolation and more lightweight resource utilization. It is an embeddable sandbox, positioned as "the sqlite of VMs".
HN Column View
This app provides an alternate column-based reading view for Hacker News with resizable font options, built as a personal hobby project.
Independent AI theory research
An ongoing independent research project on the theory of artificial intelligence, continued by the author despite uncertain odds.
PhotoGather
iPhone app that virtually stitches a user's entire photo library into a single gigapixel image navigated with pinch and zoom. On import it hierarchically groups photos by date and similarity, and users can edit groups, change the layout, and adjust photo sizes. Under the hood it computes best-fit rectangles for arbitrary thumbnail aspect ratios so groups recursively stitch into rectangular thumbnails, and the zoom UI works directly from nested thumbnails without tiling.
Nokia 1100 Linux LTE replacement motherboard
This project is a replacement motherboard for the Nokia 1100 that runs Linux and supports LTE. It uses an Allwinner T113-S3 SoC and a Quectel EC25 LTE module, with voice calling over LTE working (tested on T-Mobile in the US, which is tricky due to carrier rules). The software runs on a MangoPi dev board, and two PCBs have been designed: a test-fit board that breaks out the phone's keypad/LCD to pin headers, and the actual full board with everything on it.
Grasshopper
A tab manager extension for the Firefox browser.
Meltdown
An AI harness made in Python and tkinter, with screenshots and descriptions available on its website.
Weight loss blog
A weight loss blog the author writes regularly, asking the AI Kimi to review the posts.
Switcheroo
Switcheroo is a simple, transparent tool that switches which account's usage is billed during a CLI session, letting users juggle multiple paid accounts for AI CLIs like Claude, Codex, and Gemini, as well as other CLIs like Vercel, Netlify, and GitHub, without changing configuration. It addresses hitting per-account usage limits mid-conversation when working across 2-3 subscriptions.
dub-anything
This tool generates subtitles and dubs for any video in the actors' own voices, making previously untranslated media watchable in English.
okular-mupdf-ng
This project hardens Linux document readers by sandboxing their most dangerous components, starting with Okular's document parser and renderer, to reduce the reader's attack surface.
OneBusAway (OBA)
A suite of open source public transit software projects (OBA) run by the Open Transit Software Foundation, used by millions of transit riders every day around the world. Includes rider-facing apps, campus transit web apps, vehicle location software, and the next-generation Maglev server, with open volunteer roles for developers, biz dev, UX designers, and product managers.
Wayfinder
An open source public transit web app from the OneBusAway suite, deployed by University of California San Diego to serve its 35,000+ students.
Waystation
An open source public transit web app from the OneBusAway suite, deployed by University of California San Diego to serve its 35,000+ students.
Vehicle Positions
Free, open source vehicle location software from the OneBusAway suite that runs on commodity smartphones, preparing for launch.
Maglev
Next-generation server software from the OneBusAway suite that adds support for newer transit data formats, such as GTFS-Flex, so demand-responsive transit systems can be shown on the map.
Self-hosted colo migration of abound.art
This project migrates the abound.art application off GCP (where hosting costs $200/mo) to a self-racked PowerEdge R7625 server in a nearby colo, running on the author's own IP addresses and ASN (AS55078), including peering via an IXP.
DIY bright lamp (Brighter/Rhythm-style)
This DIY project builds a high-output bright lamp similar to commercial products like Brighter and Rhythm, but for a few hundred dollars instead of $1-2k. The parts are specced, hardware designed, and firmware built; the final 500+ W version uses LEDs cooled by a chunky aluminum heatsink and Noctua PC fans, with a first LED bench-supply test underway to validate the cooling solution.
Whistle Enterprise
A document generation product whose underlying model the author is actively improving, fine-tuning and testing small language models as replacements for Phi4, which previously performed well for midrange laptop CPU inference balancing speed and quality.
APIKulture
A native desktop API client built with C++ and wxWidgets as an alternative to Postman, Insomnia, and Bruno. It remembers JSONPath expressions between requests, is lightweight at about 40MB of RAM (versus ~400MB for the alternatives), and is designed to be fast. The author uses it daily.
