Appeals Court Strikes Down FCC's Net Neutrality Rules

A US appeals court overturned the Federal Communications Commission's (FCC) net neutrality rules. These rules mandated equal treatment of all internet traffic by broadband providers, prohibiting preferential treatment. The court's decision partly relied on last year's Supreme Court ruling in Loper Bright, which limited regulatory agency power by overturning the Chevron Doctrine. The FCC chair called for Congressional action to enshrine net neutrality in federal law, while another commissioner lauded the decision as a reversal of the Biden administration's regulatory overreach.

Improving F# Error Handling: Introducing FaultReport

2024-12-22

This article critiques the shortcomings of F#'s Result type in error handling, highlighting inconsistencies in error types and the problems stemming from using strings as error types. The author proposes FaultReport as an alternative, using an IFault interface to standardize error types and a Report<'Pass', 'Fail> type to represent operation outcomes, where 'Fail must implement IFault. This ensures consistent and type-safe error handling, avoiding the inconveniences of string-based errors. FaultReport further provides Report.generalize for upcasting and a FailAs active pattern for downcasting, facilitating handling of diverse error types. While replacing FSharp.Core's Result is a significant undertaking, the author argues that FaultReport's design offers a valuable improvement to F#'s error handling.

The Case for Fewer Dependencies in Rust

2025-01-24

Armin Ronacher, a renowned developer, laments the over-reliance on external crates in the Rust ecosystem in a recent blog post. He argues that excessive dependencies lead to constant updates, patches, and security audits, burdening developers and often introducing unnecessary code bloat. He advocates a "build it yourself" philosophy, encouraging developers to write their own code when appropriate instead of blindly relying on external libraries. He uses the `terminal_size` crate as an example, illustrating how a simple function depends on multiple crates and has undergone numerous updates, highlighting the drawbacks of over-dependency. The post calls for a shift in the Rust community's perspective, prioritizing fewer dependencies and celebrating developers who create low-dependency libraries.
