When a platform started with total developer autonomy, teams felt overwhelmed and ended up solving the same problems in completely different ways. The company shifted to enablement over support, working together with teams intensively, and helping teams feel confident and capable, turning the right way into being the easiest way.

Anthropic's usage analytics dashboard is only available to Team and Enterprise org admins. On a Pro or Max plan all you get is /usage and the claude.ai usage page, which show where you stand right now but not where you're heading. I looked at various open-source projects but none quite matched what I had in mind: an all-round control panel for Claude Code that's also a single binary, with no dependencies and no install steps. The other thing I cared about was forecasting the usage limits. Existi

It’s the first estimate of how many Americans are sneaking onto Polymarket’s banned crypto-based platform.

In 2018, after nearly two decades working in Big Pharma, chemist Tim Cernak was ready to put his skills to a new use. For Merck, he’d developed precision therapies for cancer, HIV, and diabetes that could target disease while minimizing harm to healthy cells. But as a lifelong nature lover, he was increasingly concerned about…

It’s a tale of two nuclear industries. In China, large reactors are coming together at a stunning pace. The country has nearly doubled its nuclear fleet since 2016, reaching nearly 60 gigawatts of total power capacity. The new facilities are nearly all gigawatt-scale pressurized-water reactors. Meanwhile, the US has built just two reactors in that…

You've built todo apps, counters, and forms. But can you handle a grid of 50 cells that reference each other through formulas? This challenge pushes your state management skills into real spreadsheet territory — formula evaluation, two-way cell bindings, and an interface that juggles editing, selection, and keyboard shortcuts all at once. 🔥 Start the Challenge Now 🧩 Overview Build a spreadsheet with real-time formula evaluation. You'll wire up a 10-row × 5-column grid where cells support basic values and Excel-style formulas (like =A1+B2), column and row selection, and a formula bar that mirrors what you're typing. ✅ Requirements Render a spreadsheet with column headers A through E and rows 1 through 10 Each cell uses an <output> element for the computed value and an <input> overlaid for editing Click a cell to edit; press Enter or blur to commit the change Formulas starting with = must be evaluated: Arithmetic: =1+1 → 2 Cell references: A1= 5 and B1= =A1+3 → 8 Click a column header to select/deselect that column Click a row number to select/deselect that row Selecting a column deselects any row and vice-versa Backspace clears the selected column or row Click outside the table deselects everything A formula bar ( fx ) mirrors the editing cell's value Cells must start empty — no default values 💡 Notes Use useState for cells, selected column, and selected row. No need for useReducer here. Each cell uses two overlapping layers: a visible <output> for the computed value and an invisible <input> for the raw formula. Toggle with opacity-0 / opacity-100 so the input stays mounted. Evaluate formulas with eval : generate JS const declarations from all cell values, wrap them in an IIFE, and evaluate. Recompute every cell on any change — cells can reference each other. 🧪 Tests renders the app title renders the spreadsheet with column headers A-E and rows 1-10 renders cells with initial empty values allows editing a cell and displays the new computed value evaluates a simple fo

Not a hiring post. I have a 9-5 but also a lot of ideas I want to build. The core is just to show up and make small progress — but I find I'm missing accountability and partnership, so I thought it'd be nice to partner with someone. Mostly backend/infra stuff.
