Developer builds local 3D file sorter using JavaScript, no AI or cloud needed

·1 views

A developer created MakerX 3D File Sorter, a desktop tool that automatically organizes 3D printing files — including STL, 3MF, OBJ, and STEP formats — into category folders without relying on any LLM or cloud API. The tool was built to solve the common problem of unmanageable model libraries that accumulate faster than users can manually sort them. Built with Electron 28, Three.js, and plain JavaScript, the classifier uses deterministic, offline logic rather than AI, meaning it works without an internet connection and incurs no per-user API costs. File previews are rendered locally, and all filesystem operations are handled in the main process, ensuring user files never leave their machine. The project is open source and available on GitHub, packaged as a Windows installer via electron-builder.

Google Gemini Launches Study Notebooks With Quizzes, Flashcards and Progress Tracking

Google has introduced Study Notebooks in Gemini, a structured learning workspace designed to help students organize course materials and generate personalized study content. The feature allows users to upload notes, PDFs, and websites, then have Gemini create diagnostic quizzes, bite-sized lessons, flashcards, and practice quizzes based on those sources. A progress dashboard tracks a learner's journey through the workflow, moving beyond one-off AI interactions toward a repeatable study sequence. The rollout is available globally on the web in all languages, with mobile support expected later in the summer. Google frames Study Notebooks as part of a broader education push alongside related tools such as NotebookLM and Google Classroom.

Five Common Laravel Authorization Problems and How to Solve Them in 2026

As Laravel applications grow, developers frequently encounter authorization challenges including role explosion, exception handling, multi-tenancy, contextual permissions, and cache-related debugging issues. Basic role-based access control (RBAC) often breaks down over time, leaving authorization logic scattered across controllers, policies, middleware, and templates with no single source of truth. Modern authorization patterns address these issues by supporting dual permission channels — role-based and direct user-level grants or denials — where explicit denials take highest priority. Wildcard permissions and per-tenant permission scoping further reduce the need to create redundant roles for edge cases. A package called Laravel Permission Manager is presented as a consolidated solution, with comparisons drawn against the widely used Spatie permissions library.

Five Reusable Agent Skills Released for OpenCode and Claude Code Workflows

A developer has published five portable agent skills designed to streamline common tasks in OpenCode and Claude Code environments. The skills cover AI writing detection, precise text counting, webpage-to-PDF conversion, task completion notifications via ntfy, and structured research packaging in Markdown format. Each skill can be installed by placing its folder in the appropriate agent configuration directory, such as ~/.config/opencode/skills/ for OpenCode or .claude/skills/ for Claude Code. The collection aims to replace repetitive prompts with reusable, inspectable workflows that agents can trigger automatically when a task matches a skill's description. A full index of published skills is available for developers looking to extend or browse the growing library.

How a timestamp mismatch breaks telemetry replay — and the fix that solves it

A developer building a flight-instrument replay system discovered that React telemetry components rendered blank time-series charts despite receiving correct recorded data. The root cause was a timeline mismatch: charts anchored their x-axis to the current wall clock, so samples timestamped an hour in the past fell outside the visible window and were silently discarded. Single-value instruments were unaffected because they display the latest reading regardless of when it was recorded. The solution separates two timebases — recording time for the scrubber and wall-clock time for the components — and re-stamps each outgoing sample using an anchor offset calculated at the moment playback starts or resumes. This approach lets existing components consume replayed data without any modification to their internal logic.
