Rust, C++, and the Tradeoffs Behind Safe Low-Level Code: interview with Nikita Lisitsa

Rust, C++, and the Tradeoffs Behind Safe Low-Level Code: interview with Nikita Lisitsa

⋅

In this post, we interview Nikita Lisitsa about C++, Rust, systems programming, and game development. We discuss whether C++ is still the default path into systems programming, where Rust fits in, and how both languages may coexist over the next decade. Nikita also shares his perspective on memory safety, language complexity, game engine design, real-time physics simulations, renderer abstractions, and the lessons he learned from shipping Costa Verde. Rust advertises its “if it compiles – it works” stance […]

datasette-agent-edit 0.1a0

Release: datasette-agent-edit 0.1a0 I’m planning several plugins for Datasette Agent which can make edits to existing pieces of text – things like collaborative Markdown editing, updating large SQL queries, and editing SVG files. Agentic editing of text is a little tricky to get right. My favorite published design for this is for the Claude text editor, which implements the following tools: view – view sections of a file, with line numbers added to every line. str_replace – find […]

Aitken acceleration before Aitken

⋅

Kepler solved his eponymous equation M = E − e sin(E) by finding a fixed point of E = M + e sin(E). So guess a value of E and stick it into the right hand side. Then plug that value into the right hand side again. Kepler said a couple iterations should be enough. And a couple iterations are enough if the eccentricity e is small and you don’t need much accuracy. The rate of convergence is determined by e. Kepler implicitly […]

The Laplace limit

The Laplace limit

⋅

An earlier post discussed how to solve Kepler’s equation M = E − e sin(E) using a sine series. You could also solve Kepler’s equation using a power series, which Lagrange did in 1771. Both approaches express E as a function of e and M, but from different perspectives. Bessel thought of his solution as a sum of sines in M, with coefficients that depend on e. Lagrange thought of his solution as a power series in e whose coefficients involve sines in M. You can […]

A crank formula for π

A crank formula for π

⋅

I ran across a cranky formula for π based on physical constants here and decided to play around with it. The source describes λ as “wavelength (chosen in the microwave region)” and I thought perhaps you could chose a value of λ to make the equation work. But as a comment pointed out, the bracketed expression is simply 2hc², independent of λ, due to Planck’s blackbody law. That means we can simplify the expression above to Now the […]

Inteligencia artificial del grifo… pero con los fontaneros incluidos

Inteligencia artificial del grifo… pero con los fontaneros incluidos

⋅

La promesa de la inteligencia artificial más avanzada siempre ha sonado como la de un servicio público: inteligencia abundante, disponible bajo demanda, tan fácil de utilizar como la electricidad, el agua o la computación en la nube. La metáfora es potente, y con razón. Los servicios públicos escalan porque abstraen la complejidad: no necesitas un ingeniero de la compañía eléctrica sentado en tu oficina cada vez que enciendes la luz. Y, sin embargo, las empresas de inteligencia artificial […]

Research collection of Arxiv whitepapers [R]

Research collection of Arxiv whitepapers [R]

⋅

I read and collected Arxiv whitepapers starting after the launch of ChatGPT. I copied and pasted excerpts into Word to track them. Then migrated to Obsidian. That vault of some 1700 papers is now online. I figured it was time to see if others would find the collection useful. My whitepapers were organized into some 90 categories, all of which emerged from paper topics. New categories became necessary with the discussion of new methods, techniques, models etc. If […]
