Saying Goodbye to CSS Classes: Building a Classless Website

2025-09-18

Following a previous post advocating for leveraging browser built-in elements, the author put this philosophy into practice by completely removing all CSS classes from his personal website. He experimented with more granular default styles, nested selectors, modern CSS features like `:where()` and `:has()`, and custom elements and attributes as replacements. While this requires more careful planning and isn't suitable for all projects, the experiment led the author to question the necessity of CSS classes and has had a lasting influence on his future work. A small concession was made for a syntax highlighting plugin which utilizes classes.

Rendezvous Hashing: A Distributed Hashing Algorithm with Excellent Load Balancing

2025-09-18

Rendezvous hashing solves the distributed hash table problem by generating a prioritized server list for each key and selecting the first server. Unlike consistent hashing, it offers superior load balancing but has an O(N) lookup time. It's a good choice for small to medium-sized distributed caches, but adding servers in larger systems requires careful management to maintain the "first choice" invariant. Its popularity lagged behind consistent hashing, possibly due to a lack of a 'killer app' moment, despite its earlier invention and inherent advantages.

C# 14's Null-Conditional Assignment Operator: A Farewell to Redundant `if` Statements

2025-09-18

C# 14 introduces a game-changing feature: the null-conditional assignment operator. This elegantly solves the long-standing problem of NullReferenceExceptions in C#. Previously requiring multiple `if` statements to check for null values, assignments are now streamlined to a single line, dramatically improving code readability and reducing verbosity. For instance, `config?.Settings?.RetryPolicy = new ExponentialBackoffRetryPolicy();` replaces cumbersome `if` checks. While the operator doesn't support increment/decrement operators and overuse should be avoided, it's a valuable addition in C# 14, worth exploring once .NET 10 is released.
