The author criticizes C's assignment expressions and pre/post-increment/decrement expressions for being hard to reason about due to their side-effectful nature. They argue that these expressions make code harder to understand by burying side effects within trees of expressions.

Linking Smaller Haskell Binaries (2023)

https://brandon.si/post_images/linking-smaller-haskell-binaries/folded.gif
Haskell binaries can be large due to transitive dependencies, but two strategies can help at link time: emitting code in minimal sections and using link-time dead code elimination.

Wide logging: Stripe's canonical log line pattern

https://alcazarsec.com/og/alcazar-landing.png
Stripe and Amazon use canonical log lines, also known as wide events, to log structured records per unit of work with all important fields attached. This pattern is useful for querying complete rows and allows for better analysis and diagnosis by including business context and execution context in the same row.

The author built WorldView, a 3D Earth model with real-time data feeds, including satellite orbits, CCTV cameras, and military-grade shaders. This project showcases spatial intelligence, making the physical world queryable and programmable.

Why One Key Shouldn't Rule Them All: Threshold Signatures for the Rest of Us

https://eric.mann.blog/wp-content/uploads/2026/03/czNmcy1wcml2YXRlL3Jhd3BpeGVsX2ltYWdlcy93ZWJzaXRlX2NvbnRlbnQvbHIvdXB3azYxNzY5MjA4LXdpa2ltZWRpYS1pbWFnZS1rb3dibGNwMi5qcGc.webp
Threshold ECDSA signatures split a private key across multiple parties, making it harder for a single party to compromise security. The DKLS23 protocol is a practical and secure way to implement threshold ECDSA, suitable for production use.

A sufficiently detailed spec is code

https://haskellforall.com/imgs/a-sufficiently-detailed-spec-is-code/comic.jpg
The author argues that agentic coding's claim to generate code from specifications is misleading, as these specifications often resemble code themselves. The author also claims that generating code from specifications doesn't reliably work.

A new study by Columbia University researchers found that US cities with the most shooting-free days include San Diego, Phoenix, and Jacksonville, while Chicago had the lowest. The study suggests using shooting-free days as a metric to identify effective interventions and sustain periods of peace.

FAQs About the Public Debt

The Bureau of the Fiscal Service reports and accounts for the US public debt, but does not have decision-making authority. The debt is financed through Treasury securities sold to the public and government trust funds.
