WebAssembly Moves to Backend Servers, Booting Microservices in Under 2ms

·1 views

WebAssembly, widely known as a browser technology, is increasingly being adopted for backend server workloads, offering dramatically faster startup times and lower memory usage than traditional containers. Unlike containers that bundle a full operating system, Wasm modules run inside a secure sandbox and receive only the specific resources they need. The WebAssembly System Interface, or WASI, enables these modules to interact with files, clocks, and network routes on real servers in a standardized way. This makes Wasm particularly attractive for intermittent workloads like task schedulers and data pipelines, where spinning up a full container is inefficient. However, the ecosystem still lacks mature tooling, with database drivers, logging utilities, and debugging support remaining works in progress.

MLCC Supply Crunch in 2026 Drives Sharp Price Hikes for Industrial Components

Multilayer ceramic capacitor (MLCC) prices are rising sharply in 2026 due to a significant supply shortage in the market. No new production capacity was added across the industry during 2024 and 2025, following a prolonged period of weak demand. High-capacity MLCC manufacturing requires a lead time of at least 12 to 18 months, making it difficult to quickly scale up output. As a result, the supply gap has widened rapidly, causing prices to spike and raising costs for industrial applications such as electronic switches.

How Suspense, Partial Prerendering, and Cache Components Work Together in Next.js

A technical deep-dive on DEV Community explains how React Suspense is a core building block of Next.js Partial Prerendering (PPR) and the Cache Components model. Components are rendered statically at build time unless they contain dynamic elements such as runtime APIs, uncached data fetches, or draft mode. When a route mixes static and dynamic components, Next.js prerenders the static content into an HTML shell at build time and streams dynamic content to the client at request time. This optimization means only dynamic components run at request time, improving overall page delivery performance. Routes that combine static and dynamic components require Suspense boundaries to wrap the dynamic parts, enabling this streaming behavior.

How to Build Stripe Web Checkout in a .NET MAUI App After Epic v. Apple Ruling

Following the Epic v. Apple injunction, US App Store apps can now direct users to external web payment flows, bypassing the store's 15–30% commission cut. A technical guide outlines an architecture using ASP.NET Core and .NET MAUI, where a Stripe-hosted checkout page is opened in the device's system browser rather than a WebView, a requirement for app store compliance. Subscription entitlements are granted server-side via Stripe webhooks rather than client-side claims, preventing fraud and enabling purchases made outside the app to unlock in-app features. A key implementation detail is setting the ClientReferenceId field in the Stripe session to link anonymous checkout sessions back to authenticated users when webhook events fire. The same pattern applies to Google's external-offers program and works across any technology stack, with the app checking both store SDKs and the backend API to determine a user's subscription status.
