Whether you&rsquo;re consuming REST APIs, downloading files, or communicating with microservices, your choice of HTTP client library has a direct impact on your code&rsquo;s readability, maintainability, and performance. In the .NET ecosystem, three options stand out: <strong>RestSharp</strong>, <strong>Refit</strong>, and the built-in <strong>HttpClientFactory</strong>. Each takes a fundamentally different approach to HTTP communication, and choosing the wrong one can lead to verbose, error-prone code — or worse, socket exhaustion under load.</p> https://www.pistack.xyz/posts/2026-08-02-csharp-inmemory-caching-libraries-memorycache-lazycache-fusioncache/ Sun, 02 Aug 2026 00:00:00 +0000 https://www.pistack.xyz/posts/2026-08-02-csharp-inmemory-caching-libraries-memorycache-lazycache-fusioncache/ <h2 id="introduction">Introduction</h2> <p>Caching is one of the most effective ways to improve application performance — a well-placed cache can reduce database load by 90% or more while cutting response times from hundreds of milliseconds to microseconds. In the .NET ecosystem, developers have three tiers of in-memory caching libraries to choose from: the built-in <strong>MemoryCache</strong>, the lightweight wrapper <strong>LazyCache</strong> (1,756 GitHub stars), and the feature-rich hybrid <strong>FusionCache</strong> (3,850 stars).</p> https://www.pistack.xyz/posts/2026-08-02-python-audio-processing-libraries-pydub-librosa-soundfile/ Sun, 02 Aug 2026 00:00:00 +0000 https://www.pistack.xyz/posts/2026-08-02-python-audio-processing-libraries-pydub-librosa-soundfile/ <h2 id="introduction">Introduction</h2> <p>Audio processing is essential across a wide range of applications — from podcast editing tools and voice assistants to music analysis platforms and scientific signal processing.

Every API response passes through a serializer, and inefficient serialization can become the dominant bottleneck as your application scales. The Ruby ecosystem offers three major serialization libraries with distinct philosophies: <strong>Alba</strong> (modern, performance-focused), <strong>Blueprinter</strong> (simple, fast, declarative), and <strong>ActiveModelSerializers</strong> (the Rails conventional choice with JSON:API support).</p> https://www.pistack.xyz/posts/2026-07-31-rust-benchmarking-criterion-iai-divan/ Fri, 31 Jul 2026 00:00:00 +0000 https://www.pistack.xyz/posts/2026-07-31-rust-benchmarking-criterion-iai-divan/ <h2 id="introduction">Introduction</h2> <p>Performance is Rust&rsquo;s raison d&rsquo;être.

What started with manual framework copying gave way to <strong>CocoaPods</strong> (centralized, convention-based), then <strong>Carthage</strong> (decentralized, build-your-own), and finally <strong>Swift Package Manager (SPM)</strong> — Apple&rsquo;s official, integrated solution.

Unlike Rust (cargo), Go (go mod), or Node.js (npm), C++ has no standard build system or package manager.

Every microservice that communicates over a network, every message queue that persists events, and every cache that stores objects must serialize data. Java&rsquo;s built-in <code>Serializable</code> interface has been the default for decades, but it is slow, verbose, and a well-known security vulnerability vector.
