Wasp swaps DSL for TypeScript, Firefox adopts Rust zlib-rs

Wasp has replaced its custom DSL with a native TypeScript spec, letting you define full‑stack app logic in *.wasp.ts files. This gives developers type safety, IDE support, and a single language across front‑end, back‑end and database layers, accelerating iteration on React‑Node projects.

A Rust service that frees work items still shows high memory usage because jemalloc keeps thread‑local caches alive. Switching to the system malloc or tuning the allocator releases the retained memory, turning a perceived leak into a normal allocation pattern.

WAI‑ARIA 1.3 introduces document.ariaNotify(), a JavaScript method that lets you push spoken messages to screen readers without inserting live‑region elements. This gives developers a clean, programmatic way to deliver urgent alerts or status updates, cutting the brittle DOM hacks that have historically been required for accessible notifications.

Firefox 151 now uses the Rust‑written zlib‑rs for gzip compression, swapping out the legacy C library. The switch delivers faster, memory‑safe decompression and required a few symbol‑prefix tweaks and a quick fix for an Intel Raptor Lake CPU bug that surfaced after deployment. This marks a key milestone for Rust in core browser code.

The IETF just standardized the HTTP QUERY method, a safe and idempotent request that can carry a body. It lets clients send complex query payloads while still enabling caching and automatic retries, closing the gap between GET’s limits and POST’s side‑effects.

Lore is a centralized, content‑addressed version control system written in Rust, built to store large binary game and film assets efficiently. It stores repository state as Merkle trees, providing deduplication and on‑demand data hydration, which can cut storage costs and speed up collaboration on massive files.

Prop For That injects live CSS custom properties for values browsers can’t normally expose, cursor coordinates, scroll velocity, form states, time, etc. Import the tiny script, add data‑props attributes, and style directly in CSS, opening a new class of interaction without custom JavaScript.

On a 2022 M2 Mac, the author runs Gemma‑4‑26B locally and achieves about 75% of frontier model accuracy for coding tasks. Refactoring, linting, unit‑test generation, and basic agentic workflows now run reliably without API calls, proving local LLMs are practical for everyday development.

Bayer’s PRINCE platform shows how to turn LLMs into a production‑ready research assistant for drug discovery. The case study details orchestration, recovery, observability and human‑in‑the‑loop safeguards that keep the system trustworthy at scale. It proves agentic AI can cut data‑access time while meeting regulatory compliance.

Since AI models like Opus 4.5 can now write code at a median engineer's level, the old myth that AI lets teams skip code review is busted. In reality, developers must double down on testing, static analysis, and rigorous review to catch subtle bugs AI introduces. The shift will redefine quality gates across the industry.

Meta’s new AI‑first strategy is forcing engineers to adopt generative tools at breakneck speed, scrapping the stable‑infra culture that made the org a profit centre. The shift has triggered costly outages, demoralized senior talent, and turned engineering into a cost centre. Future hires and product reliability now hang in the balance.
