🌱 Last Frost: A Garden Planner That Only Works If You Go Outside

·4 views

This is a submission for the Hacktoberfest Open-Source AI Challenge Week 1: Touch Grass Last Frost is an offline garden planner. You type your ZIP code and what you want to grow; it looks up your local first fall frost and last spring frost dates, then a small open-weight model running on your own machine tells you what to plant this week, what to hold back, and why — based on the actual number of frost-free days you have left. It's for anyone whose gardening app experience is: open app → get generic advice → still not know if it's too late to plant tomatoes. Last Frost replaces "generic" with

PHP PDF generation becomes slow when creating large documents

I am working on a PHP-based worksheet generation system and recently ran into a performance problem. The application generates printable PDF files based on user-selected options.

Hi everyone 👋 I'm Andrea, a full-stack developer from Italy, living in Tenerife. Yes, that one, the island with the big Teide, a volcano, which is maybe why I ended up building this.

No GIS, no projections, no OpenLayers.

Jev-LCT: Free Calibrated Confidence from Looped Transformer Trajectories

Small decision models have two bad options today: generate text token-by-token (slow, fragile to parse), or "introspect" their confidence verbally (systematically miscalibrated). Jev-LCT is an open-source System-One decision engine that takes a third route — extracting calibrated probabilities directly from a transformer's internal recurrent dynamics. Parallel Looped Prefill: recurrently recomputes only the top k=2 layers of a causal transformer, preserving full representation fidelity. Endogenous Trajectory Confidence: reads calibrated probabilities from hidden-state convergence dynamics (cos

When Does an Ecommerce Application Need Custom Software?

Starting an ecommerce business does not always require building everything from scratch. For many businesses, an existing ecommerce platform can handle products, carts, checkout, payments, and basic order management effectively. The situation changes as the business grows. Complex pricing rules, multiple inventory locations, legacy systems, custom workflows, and large product catalogs can introduce requirements that standard features don't always handle well. At that point, the question becomes: Should we extend the existing platform or build custom software?
