Feed aggregator

I deal with massive JSON APIs daily and got tired of pasting sensitive payloads into random cloud formatters. So I built J-RAY. It runs 100% locally in your browser (0 trackers, data never leaves your machine) and transforms chaotic JSON into an interactive neural graph to make debugging easier. Built with React and ReactFlow. Would love your feedback!

I made a chess engine today, and made it fit within 2KB. I used a variant of MinMax called Negamax, with alpha beta pruning. For the board representation I have used a 120-cell "mailbox". I managed to squeeze in checkmate/stalemate in there, after trimming out some edge cases.

I am a great fan of demoscene (computer art subculture) since middle school, and hence it was a ritual i had to perform.

For estimating the Elo, I measured 240 automated games against Stockfish Elo levels (1320 to 1600) under fixed depth-5 and some constrained rules, using equal color distribution.

Then converted pooled win/draw/loss scores to Elo through some standard logistic formula with binomial 95% confidence interval.

I’ve been studying a behavioral pattern I see in capable, ambitious people.

They don’t usually quit.

They restart.

They build a system, execute for several days, miss once, then redesign everything instead of continuing.

I call it the Continuity Collapse Pattern.

The core idea:

Most productivity systems are built for ideal conditions. Real life includes emotional variance and activation cost. When a miss is interpreted as identity failure, restart becomes the default response.

The solution isn’t more motivation. It’s designing systems around return speed instead of streak length.

Full breakdown here:

Hi everyone,

I've made an early version of a Datalog engine (called Zodd) in Zig. Datalog is a logic query language. It's not as well-known as SQL, but it has its own use cases. If you're interested to know more about the project, including its possible use cases and features, you can check projec's GitHub repo: https://github.com/CogitatorTech/zodd

For a clean main context, convenient application management, and potentially unlimited scalability, an AI workstation based on Claude Code skills was created, referencing computer architecture : { CPU ==> LLM }, { System Kernel ==> Claude Code + CLAUDE.md }, { System Processes ==> Sub-Agents }, { Apps ==> Skills }, { Appstore ==> github }, { System Drivers ==> MCP + Hooks }, { Monitor ==> Windows Terminal }, { Runtime Environment ==> Portable Environment }; The Code: https://github.com/canishowtime/ai-station-navigator/

Hi! I made a two-dimensional phase portrait plotter website page.

Purpose: If you don't have any study guide for exercises related to dynamic systems or too lazy to run python and set up sliders to visually see potential bifurcations, you can play around with said dynamic system (numerically) to visually get a feel of the system.

It includes numerical approximations for:

- Euler/4th Order Runge-Kutta solver for the system --> You can also pick initial point + backwards integration.

- Poincaré Index (index theory)

- Nullclines

- Eigenvalues of the Jacobian matrix (sometimes called "stability matrix" in the literature)

It's based on old python code that I made for a dynamic system course that I converted to JavaScript using Grok, Sonnet 4.5 and Gemini Pro.

Does not include:

- Bifurcation diagrams - can't make it without a computer algebra system (CAS), way above my skill level...

- Anything that isn't two-dimensional (for one dimension you can just use a regular calculator) - 3D got highly computational heavy fast (for a website so to speak). I'm keeping it simple since it is a practice tool to draw your own phase portraits yourself by hand (like most exams requires you to do).

For real applications, you need to either solve stuff analytically or use more advance tools. This is just for educational purposes and enjoyment.

Context: Earlier this week asked how engineers "step through" their own anxiety. 20+ comments with methods: externalizing, nervous system regulation, "next thought" hack, 4-mile walks.

Built a tool for the gap: 2am, 6 layers deep, can't access your toolkit. 10 Socratic messages, no login, no memory.

Not therapy. Not optimization. Just pattern recognition when you're stuck mid-loop.

Thanks to everyone who shared their actual practices.

While lagging behind in other areas, Google's flagship is a standout in showing gameplay.
