Durable Task .NET SDK: Five Real-World Use Cases and When Not to Use It

·1 views

A developer deep-dive examines the practical use cases for the Durable Task standalone .NET SDK (v1.26.0), moving beyond theory to real-world scenarios. The article walks through five examples — invoice approvals, Azure tenant provisioning, subscription payments, out-of-order webhooks, and AI-driven incident investigation — to evaluate where durable execution genuinely helps. Durable Task is positioned as most valuable when workflows are long-running, depend on external systems, or risk being interrupted mid-execution. The piece also cautions against over-engineering, noting that some scenarios are better served by queues, databases, or simple background workers. Crucially, the author reminds readers that durable history does not guarantee exactly-once external effects, an important nuance for production use.

Why HTTP/3 Replaced TCP with QUIC to Fix Web Protocol Bottlenecks

HTTP/3 is the latest version of the web's core data transfer protocol, built to address fundamental limitations in its predecessor HTTP/2. While HTTP/2 improved on HTTP/1.1 by enabling multiple streams over a single TCP connection, it still suffered from head-of-line blocking — where a lost packet stalls all streams sharing that connection. HTTP/3 resolves this by replacing TCP with QUIC, a transport protocol that runs over UDP and handles streams independently, so one lost packet no longer delays unrelated data. QUIC also reduces connection setup time and supports smoother network migration, such as switching from Wi-Fi to mobile data. The core HTTP semantics — methods, status codes, headers, and caching — remain unchanged; only the underlying transport layer is different.

How PostgreSQL Handles Table Bloat: Autovacuum, VACUUM, and VACUUM FULL Explained

PostgreSQL does not immediately remove old row versions after updates or deletions, instead relying on MVCC, which can cause tables to accumulate dead tuples and consume excess disk space. Three mechanisms address this bloat: Autovacuum runs automatically in the background to mark dead tuple space as reusable without locking the table, while manual VACUUM does the same on demand. VACUUM FULL goes further by physically rebuilding the table with only live rows and returning unused space to the OS, but requires an exclusive lock that blocks all concurrent access. A demonstration using a 2-million-row table showed that deleting 1.8 million rows left the physical table size unchanged at 1116 MB until a vacuum operation ran. This highlights that reclaiming actual disk space in PostgreSQL requires deliberate use of the appropriate vacuum strategy depending on downtime tolerance and storage needs.

Developer releases glyphed.js, a zero-dependency TypeScript handwriting animation library

A developer has released glyphed.js, an open-source TypeScript library that renders text, icons, and charts as animated SVG strokes that draw themselves when scrolled into view. Unlike static script fonts, each character is built from real monoline SVG paths and includes randomised variants, slight rotation, and baseline drift so no two renders look identical. The library requires no external dependencies and uses only CSS transitions and IntersectionObserver for animation. It supports 68 tree-shakable icons, several annotation styles, and bar, line, pie, and donut charts with handwritten labels. The package is available on npm and GitHub, and the developer is actively seeking feedback on glyph shapes and usability.
