Lite³: a binary format encoding JSON documents as a serialized B-tree, making it possible to construct iterators on them directly and query internal fields at indexed speeds. It is still a serialized document (possible to send over a network), though now you don't need to do any parsing, since the document itself is already indexed.
I want to become a software professional, but I don't really know how I can do it. Focus on studying for many certificates or go to work or study at a higher level in school... Now AI is developing very fast; Claude can code very fast for every feature in my project, so I think I'm about to lose my job.

I just finished building my own IoT platform and I’m honestly so proud of it.
It’s completely free. Please try it out it would mean the world to me! Would love some feedback.
N.B. Finished the landing page and docs this morning. Done I’d better than perfect so expect some rough edges.
ResumeUp.AI - An AI powered career platform for ATS optimised resumes, cover letters and the tools like job tracker, one-click tailoring, linkedin optimisation to empower your job search.
I am working on way too many things to add here but one of them is https://www.familygpt.chat - ChatGPT for kids with parental control. I built it for my kids.
If you want the full list of projects (11 apps, 3 podcasts and some books) see https://www.emadibrahim.com
Started a newsletter [1] focused on agentic coding updates, nothing else. Other newsletters/blogs cover a lot of generic AI news, industry gossip, and marketing fluff. Having a focused feed is something I wanted for myself and finally I have enough time that I can write this newsletter regularly.
https://thingg.co -- A group of very smart people working on an incubator for our pet projects in a co-op manner.
https://cipher.social -- Distributed / p2p, encrypted social networking so I can send baby pictures to my mom.
React Native mobile app + React web app that shows all the coffee shops across New York City. The idea is that you can open it and the app instantly displays the closest coffee shop to you. It integrates with Google Maps reviews AI summaries for a lowdown on the coffee shop and vibe.
Been working on https://qave.chat, Wanted Slack to be more supportive for developers so been iterating on feature parity with Slack but optimised for developer workflows.
This looks like keyboard driven commands, secrets store (to be done) and scripts that you can write and store without spinning up a new server (easier chat ops)
Still in early alpha so after a few more polish it'll be ready, but you can try it right now!
"WallMod" -> wallpaper manager and modifier and autosetter. Kinda like wallpaper engine but instead tailored specifically to static images since I don't like animated ones personally. https://github.com/DefrimBinakaj/WallMod
Open to suggestions :)
Working on CiteLLM, an API that extracts structured data from PDFs and returns citations for each field (page + coordinates + source snippet + confidence).
Instead of blindly trusting the LLM, you can verify every value by linking it back to its exact location in the original PDF.
I'm working on a collection of mnemonic images for learning written Chinese. Each has a solarpunk-style image referencing both the character's meaning and pictographic etymology, with the character overlaid and color-coded to indicate the tonality in Mandarin.
While I'm talking about it, do the folks here have any suggestions where I should make it available? I want it to be a free educational resource for whoever might want it.
I am learning C++ and ImGUI. My first app is a JSONL Viewer. Recently I‘ve added support to read parquet files (uncompressed) too.
https://iotdata.systems/jsonlviewerpro/
Next step is to integrate a visual data pipeline by using ImNodes. I‘m slowly making progress in my experiments, but C++ has a steep learning curve, especially when targeting MacOS and Windows at the same time.
I am hunting for the source code of VR-1 Crossroads
It was a mud style game in beta that ended up getting axed in the early 2000s (?) but it was brilliant and a few of us stuck around in it long after we should have.
If anyone has heard anything about it, let me know!
About all I can find publicly so far https://x.com/hellcowkeith/status/885362337384878080
I’m working on Universymbols, which lets you restyle icons to match your app’s icon set, like SF Symbols, Material Symbols, and many more.
It uses a pipeline involving several AI models, including Nano Banana and OpenAI’s gpt-image-1 for the raw image generation.
I’m building an open-source Electron desktop app for managing Claude Code, allowing users to configure various settings on user/project level, setup MCP servers, subagents, skills, see usage metrics and more https://antonbelev.github.io/claude-owl/
I've been working on a game for playdate, part time for the last year+. It's a wonderful device and community. The hardware constraints are extremely freeing, and inspires creativity. Mostly Lua, but if you want to push the boundaries, you need to go fairly low level C, and I've found pushing in those boundaries to be just a blast. It's great platform if you're interested in a game dev hobby.
I'm working on Watermark'd. We want to give businesses a verified digital identity that works across the globe starting with businesses registered in South Asia (DUNS number that works for the 21st century).
What we do is quite simple 1. Verify the business is registered in the claimed jurisdiction. 2. Verify if individuals have the authority to act on behalf of that business. 3. Provide sharable credentials.
I built a daily football (soccer) quiz a bit like Wordle but identifying 5 footballers by their career path.
Stating to get a quite a few people playing it each day now.
I suppose if it is ever to make any money it will need ads at some point but for now it is ad-free.
I’ve enjoyed making something simple and shipping it rather than trying to do something more grand.
Working on a Graph-RAG integration with Claude Code. My work has many interconnections (components used at multiple clients for example) so learning the graph db way of thinking has been very interesting. I have created my own memory mechanism and use the database to feed a personality into the experience. Tons of fun.
Creating Daino Qt - a collection of components that makes Qt apps feel and look native on both Desktops and mobiles (each with its own set of challenges).
Developing Qt apps with C++ and QML is a blast - the fast performance of C++ and ease of use of writing UI in QML. But there is so much left to be desired with the built-in Qt Quick components - mobile issues like non native text handling, non native swipe-able stack view and much more. I’m aiming to bridge that gap.
Currently polishing my game, it's a 3D troll platformer. I published the initial demo on Steam last week: https://store.steampowered.com/app/4224780/Reflex_Run/
I am using a very different tech stack for it. It is written in Clojure.
When someone dies, you don't get even one extra second to access the documents and information they meant to share it with you. Trying to fix this problem with Eternal Vault.

Another thing thats in early alpha right now is CapKit, AI professional captions for short form videos
Started working on a training plan builder after getting frustrated with trying to use an existing service (trainingpeaks) and not finding the controls intuitive enough without being a coach in their system.
I wanted something local and offline first + 10-20% better than excel, think I'm missing a few features other might find useful, but it works for my needs which has been great.
I am working on https://voiden.md/.
Voiden has API specs, tests, and docs in one Markdown file . Think of an offline API client like Postman,just better dev experience.
An everything app, for all your music, videos, work, money and more: its called E5 https://page.twentythreeinreverse.com/ or https://ipfs.io/ipns/k51qzi5uqu5dmcdach9nq8aji8tgsfsqkh1jozp...
A database desktop client, built with Tauri & SvelteKit.
"But there are many already!" I hear the crowd exclaim.
I respond, "Yes, but..."
It's really something I want for myself. Lightweight, as fast as humanly possible, extensible via plugins (in fact the entire app is mostly plugins, with a small core to glue it together), and a tiny bit of LLM (call it AI if you wish) integration to ask questions about the database or generate/review queries.
Still experimenting with data productivity tooling that doesn't rely on YAML. Been refocused on CLI tooling as a good interface for agentic use recently since Claude Code has gotten so good. Need to do some empirical evaluation on MCP/CLI success rates.
Continuing to add new features for my traefik plugin that manages bot traffic: https://github.com/holysoles/bot-wrangler-traefik-plugin
Also working on getting Nix setup on my devices, including a PR for the official installer to support OpenRC + BusyBox distros. Hopefully will get merged soon :)
I'm building a platform for people in my rare fruit meetup group exchange scions. I've never built a react native app, but with the help of Claude it seems possible to build for the web and iOS/Android apps with minimal experience. Hoping to make it really useful for our group before sharing it with others.
Bespoke, grounded, cross-referenced ontology with focus on
* wealth, power, influence
* politics
* science, math, engineering, technology
* ...
Just wrapped up the latest build of Bedtime Hero - an application (React-Native, ios, android) for parents to build/generate bed time stories with their little one. Allows the parent to use pre-sets or set their own and then generate a story (complete with images).
This was a satisfying project mostly because I dog-food it every night with my little one.
I have been slowly progressing on writing a Rust like language that compiles to JavaScript for a few years now. With the rise of AI and it becoming better recently with Opus 4.5, specially with Rust, I've been trying to have a speedrun version of it.
Think of it as TypeScript but with full algebraic types and other commodities from Rust:
I am in the final testing stages for a bespoke recommender system to facilitate construction of EDH Decks.
The vibes are off at the moment, but goal is to do a show HN and a little PR a little closer to the holidays: https://mtg.derekrodriguez.dev/
Working on a mobile app version of our daily puzzle game Fivefold: https://fivefold.ca
A fresh PWA to log / improve your coffee brewing process. We use it to see what we are all drinking, find new coffees, explore new cafes, and understand what we like / don’t like.
It’s primarily used by our group of friends, so if you see a rough edge somewhere please reach out!
I’m working on a GUI for managing CODEOWNERS for large repos with lots and lots of owners
https://Jar.Tools - online java jar files decompiler and content viewer
Im building a calendar for my car navigation system https://e39.dev
Last winter I built a Matrix client for it. This time around I want to wrap Akonadi with a DBus shim and consume that model in custom calendar widgets and UX I’m making for a rotary knob ui.
I want to run the same app on an intel atom tablet on the side of my fridge, with a Griffin PowerMate hooked up to it for input.
I've been reverse engineering a few old games I used to play a lot. Traffic Giant, Creatures 2, ... It's been interesting.
I implemented an algorithm for neural network verification called ⍺β-CROWN for a deep-learning library called tinygrad.
https://github.com/0xekez/tinyLIRPA
tinygrad’s small set of operations and laziness made it easy to implement. Tho my overall sense is that neural network verification is currently more of a research interest than something practical.
I tried the 7DFPS Game Jam this month, trying to learn a little more 3D modelling, as well as Godot. It was my first time using the engine to produce a HTML5 build.
Currently working on a code formatter and parser for Supercollider's sclang. Supercollider is an amazing language, but the development tooling is severely lacking - we need good tooling, and now with LLMs in play and my coding ability leveled up from doing GATech's OMSCS, I'm finally able to tackle this.
I'm learning rust while I'm doing this too, so it's been an experience. Fun, though.
I'm working on a game for pocketstation (essentially Dreamcast VMU, but Playstation). It has the same cpu architecture as GBA but there are some unfortunate circumstances that requires me to modify LLVM for rust to use. Forces me to learn I guess
I’ve been working on "Next Arc Research" — https://nextarcresearch.com - a wrapper around my curiosity to understand how AI, compute, and capital might change markets by 2030.
It’s not a trading tool or product. More like a weekly, machine-assisted research project. Each cycle I run analyses on 120+ public companies across semiconductors, cloud, biotech, energy, robotics, quantum and crypto. The framing is inspired by Emad Mostaque’s “The Last Economy” thesis — the idea that when intelligence becomes cheap, the physics of value creation start to look very different. I originally built it for myself and retail investors in my family but I figure it could have more general utility so prettied it up a bit.
The system uses large-model reasoning (GPT-5+ though I've also tested Sonnet, Gemini and Grok) combined with structured scoring across technology maturity, risk, competitive positioning, and alignment to AI-era dynamics. The output is static HTML dashboards, PDFs, and CSVs that track month-over-month shifts. I'm adding to it weekly.
Mostly I’m trying to answer questions like:
* Which companies are structurally positioned for outsized upside in The Last Economy?
* How should I deliver the research so that it would have been actionable to someone like me 30 years ago?
* What signals would help folks identify “the next NVIDIA” 5 years earlier?
The inference costs real $$$ so I've set up a Patreon that, hopefully, will allow me to scale coverage and extend the modelling and methodology. There is a free tier and some recent, complete example output on the web site. I'm also happy to gift a free month for folks willing to provide constructive feedback: https://www.patreon.com/NextArcResearch/redeem/CC2A2 - in particular I'm looking for feedback on how to make the research more actionable without drifting into "financial advice".
I don't collect any data but Patreon does for authentication and Cloudflare does to deliver Pages. The Last Economy is here: https://ii.inc/web/the-last-economy
A couple fun things!
A web server for my blog: https://github.com/cozis/BlogTech
And a distributed file system for which I'm also building a cool little raspberry Pi cluster! https://github.com/cozis/ToastyFS
Fun stuff!
Building a little extra tool for my reservation system, which simulates guests reserving accommodations before a customer launches. This is nice if you have no idea how users will respond to your availability and options.
We have an ML model that's trained on real reservations and use an LLM to decide why a user mightve opted out. We apply personas to this LLM to get a bit of a sense how they would probably be operating the booking flow.
https://playwriter.dev
A browser automation Chrome extension and MCP. It consumes less context than playwright MCP and is more capable: it uses the playwright API directly, the Chrome extension is a CDP protocol proxy via WebSockets.
I use it for automating workflows in development but also filing taxes and other boring tasks
