Developer Builds Free Lip Sync Animation Tool for Blender Using Rhubarb

·1 views

A Blender user with over five years of experience has released a free web-based tool that automates lip sync animation for 3D and 2D projects. The tool uses Rhubarb to analyze uploaded audio files and maps mouth movements to pre-made or custom mouth shape images. Users download the result as an image sequence, which can then be applied as a texture in Blender or other 3D software — no rigging or mesh deformation required. The developer built it using TypeScript, Supabase, a Rhubarb WASM package, and deployed it on Vercel. Originally created for Lego Brickfilm animations, the tool supports audio files up to one minute long and is freely available online.

GTK4's GListModel Replaces Manual Widget Trees for Dynamic List Management

A developer tutorial series called 'A Field Guide to GTK Widgets' has published its third entry, focusing on modern list handling in GTK4. The post explains why the traditional loop-and-append approach to building UI lists breaks down once data becomes dynamic, such as when items need filtering, sorting, or live updates. GTK4 addressed this by deprecating older tools like GtkTreeView and GtkListStore in favour of the GListModel interface, which separates data from the view layer. With GListModel and its concrete implementation GListStore, the view automatically reflects data changes without developers manually patching the widget tree. The article includes runnable Rust code split across task, row, and window files to illustrate clean separation of data and UI concerns.

Developer Seeks Feedback on Craftfolio, a Portfolio and Resume Builder Tool

A developer has built Craftfolio, a tool designed to help developers create portfolios and resumes. The project was undertaken as a personal challenge to move beyond smaller coding efforts and produce something practically useful. Craftfolio includes features such as live previews, content importing, multiple portfolio styles, HTML export, and PDF printing. The tool is still under active development, with the creator seeking community input on the user interface and overall experience. Feedback is particularly welcomed on what should be improved or removed from the platform.

Containerizing Spark Dev Environments Can Prevent Costly Production Mismatches

A dependency version mismatch between a developer's local PySpark setup and a production EMR cluster caused four hours of downtime and around $12,000 in wasted cloud compute credits last October. The root cause was a serialization error triggered by differing Scala and Java runtime versions, which only surfaced at a specific data volume threshold in production. Engineers debugging locally on host machines face a persistent risk of such mismatches due to inconsistent Java, Python, and library versions across environments. Containerizing the development environment using Docker and docker-compose — mirroring the production base image and using a local MinIO instance for S3-compatible storage — eliminates this guesswork by ensuring local and cluster environments are identical. While the containerized approach requires upfront setup time, it shifts the maintenance burden from recurring, unpredictable version conflicts to a one-time, clearly defined Dockerfile configuration.

Developer patches COSMIC desktop to add 5x5 wrapping workspace grid on Pop!_OS

A developer has patched System76's COSMIC compositor on Pop!_OS to replace its default linear workspace strip with a navigable 5×5 grid. The modification covers two components — cosmic-comp and cosmic-workspaces — both pinned to specific versions and maintained on a branch called cosmic-grid. Workspaces are arranged using row-major indexing over an existing flat array, meaning the underlying workspace model required no fundamental rewrite. Four-finger swipes move the user north, south, east, or west across the grid, which wraps at the edges and always opens at the center cell on login. A backup-and-hold install script ensures the patch can be fully reversed with a single command if a system update risks overwriting the changes.
