Open-Source Webmail Suite webmailMaquita Brings eDiscovery and DLP to Self-Hosted Mail Servers

·1 views

Developers have released webmailMaquita, an open-source webmail and collaboration suite licensed under AGPL-3.0, designed for self-hosted mail servers running Postfix and Dovecot. The platform addresses a gap in the market by offering enterprise-grade compliance features — including eDiscovery, legal hold, and data loss prevention — without requiring costly commercial licenses. Built on a React and FastAPI stack, it includes productivity tools such as calendar, contacts, Kanban tasks, and chat, alongside security features like SPF, DKIM, DMARC, and two-factor authentication. The suite also offers forensic search across mailboxes, GPG-signed email exports, and detailed event logging for end-to-end traceability. Currently tested with around 300 mailboxes and over 100,000 emails in a production environment, the project is available on GitHub and seeks community testing on clean Debian installations.

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.
