Can Partiful keep the party going?

One hundred dollars will buy you 8 pounds of glitter; 10 Domino's pizzas; 406 miniature disco balls from Temu; or 100 cans of Coors Light. For a friend's birthday party one year, Ayla D'Silva spent $100 on sour candy and made a "sour candy salad." Even sweeter was that she didn't have to foot the […]

I got tired of watching 40 Kalshi tabs, so I built a self-hosted signal monitor

I kept hearing about Kalshi. The commercials, the mentions, and then one morning CNN was talking about Kalshi prediction odds like they were a weather report. So I went and looked. And I had no idea what I was seeing. Kalshi is really hard to understand when you're new to it. You get markets, contracts, prices that are also probabilities, volume, movement, and none of it tells you what's actually worth paying attention to. I wanted something that would translate what I was looking at into something I could understand and, ideally, act on. That was the whole original goal: make the firehose legible. Then, of course, I kept adding to it, because once you can read the flow you start wanting an edge in it. Who doesn't. So Trade Hunter grew from a translation layer into a translation layer with detection on top. This is a writeup of what it became, why I made the design choices I made, and the parts I'm still not sure about. I'd rather you poke holes in it now than find the breakpoints the hard way. If you think a decision here is wrong, please let me know. The comments are the point of this post, not an afterthought. Where this came from Basically, I couldn't read Kalshi, and I wanted to. Trade Hunter is the original tool I built to fix that for myself, and it's the one I still run when I want a live view. So this isn't a polished sequel to anything. It's the thing I built because I wanted it to exist, flaws and design bets included, and I'd rather show you those directly. The core idea never changed even as I piled features on: watch live Kalshi WebSocket feeds and surface an unusual move while it's still moving, rather than reading about it after the fact, or on CNN the next morning. What it actually does Trade Hunter subscribes to live Kalshi feeds across every market you track. Multi-contract series like the Fed rate decisions or who will win Top Chef fan out automatically to all open contracts, so you point it at one thing and it watches the whole family. When some

The part of a PaaS you use most should have the least power — so I built Mooring

I have a folder on my laptop called side-projects . Most of them are Dockerized. Most of them will never see more than a handful of users. And for years, every one of them hit the same wall: getting the thing onto a cheap VPS without losing a weekend — and copy-pasting my own past mistakes forward every single time. Here's the opinion that eventually turned into a project: the part of a PaaS you touch most often should hold the least power over your server. Think of a deploy tool as two planes. There's a read plane — dashboards, logs, container health, the stuff you stare at — where you spend most of your time and which is your most exposed surface. And there's a write plane — deploy, restart, the actions that actually change the system — which is rare and should be gated. My frustration was that the thing I looked at all day and the thing that could rewrite my box tended to sit on the same pile of privilege. So I built Mooring to keep those two planes apart. It's an early, solo project, and this post is me showing it and asking for eyes on it. The mental model The whole thing, end to end: Install it as an unprivileged systemd service (not root). Connect a git repo. Write one mooring.yaml . Click Deploy. That's the loop. Everything below is what's underneath it. What it is Mooring is a small, security-first, self-hosted control plane for Docker — a tiny PaaS. You point it at a git repo, describe your app once, and it deploys and runs your containers on your own server. Same territory as Coolify, Dokku, CapRover, and Kamal — all genuinely good work. The difference I care about is the posture underneath. It ships as one static, CGO-free Go binary . It runs as an unprivileged systemd service — not root. State lives in SQLite (the pure-Go modernc driver). Every asset is embedded with go:embed , so there's no node_modules , no asset pipeline, nothing to build on the box. To be honest about the neighborhood: setting up a self-hosted PaaS, these tools tend to want broad ac

We Built Hallo Zetta Because We Were Tired of Watching Teams Answer WhatsApp on Personal Phones at Midnight

The story behind why we built a WhatsApp CRM that actually understands how WhatsApp works. There's one scene I can't get out of my head. A friend's desk. She runs an online store. On it sat three phones. Not for show. One for customer service, one for the admin, one for the number that was "just for resellers." All three buzzing, nonstop. And there she was, eleven at night, still replying to messages one by one, sighing: "It's the same questions over and over. But if I don't reply, they'll go to the competitor." That's not a rare case. That's the normal state of things for thousands of businesses. We all know one thing CRM software rarely admits: customers here don't live in email. They live on WhatsApp. They ask about prices on WhatsApp, complain on WhatsApp, close deals on WhatsApp, even ask for warranty support on WhatsApp. But the teams handling all of it? They use personal phones. No records, no context, no way to help each other when one person is drowning. Hallo Zetta was born out of that. What Frustrated Us About the Existing Tools Before building our own, of course we looked. Surely someone had solved a problem this simple? Turns out what existed fell into two camps, and both were maddening. Camp one: dumb auto-reply bots. Type "hi," get a template. But the moment a customer asks something slightly off-script, the bot freezes. It actually makes customers angrier, because it feels like talking to a wall. Camp two: bloated CRMs. Loaded with features, dashboards full of charts, but WhatsApp is bolted on as one small tab. As if WhatsApp were an afterthought, not the main battlefield. For most of our customers, WhatsApp is the battlefield. Nothing fit. So we decided to build it ourselves. The Hard Part Isn't "AI Can Reply to Messages" Let me be honest about this. Bolting AI onto WhatsApp is easy. Anyone can wire GPT to a webhook and ship it overnight. If that were the whole goal, this article wouldn't need to exist. The hard part, the thing that made us rethink

A 20-year-old HCI paper, resurrected as a Chrome extension

I missed the tiny "x" on a browser tab again today. Meant to close it, switched to it instead. Aiming a one-pixel pointer at an eleven-pixel checkbox is basically microsurgery, and somewhere along the way we all just accepted that. Here's the strange part: HCI research solved this twenty years ago. It just never shipped. The paper In 2005, Grossman and Balakrishnan published The Bubble Cursor at CHI. The whole idea fits in one sentence: Make the cursor's hit area a dynamic circle that always contains exactly one target. That turns out to be the same thing as always selecting the target nearest to the pointer. Picture the screen divided into Voronoi cells, one per clickable thing, and the cursor picking the owner of whatever cell it's currently in. The clever part is what it refuses to do. Naive "gravity" cursors snap to every link on the way to the one you actually want, and they get stuck. The bubble cursor grabs exactly one target by definition. The moment a second target becomes nearer, it switches. So it stays calm on link-dense pages, and the paper showed significant speedups in controlled experiments. Twenty years later our cursors are still naked, so I built it as a Chrome extension. It's called MagPoint . The core is about 30 lines A content script collects clickable elements ( a[href] , button , input , ARIA roles and so on) and, every frame, picks the one with the smallest point-to-rectangle distance: function pointToRect ( x : number , y : number , r : DOMRect ): number { const dx = Math . max ( r . left - x , 0 , x - r . right ); const dy = Math . max ( r . top - y , 0 , y - r . bottom ); return Math . hypot ( dx , dy ); } Clicks that land in the empty space near a captured element get re-routed to it. Past a max radius of 120px the magnet lets go, and empty-space clicks behave like the normal web. It also stands down while you type or select text, because getting yanked toward a link mid-sentence would be infuriating. The rule that kept me sane: the vis
