The post shows how ANSI escape codes control the terminal—color, decoration, and cursor movement—to build rich UIs like progress bars and a custom command-line. It demonstrates reading raw input in Python (tty.setraw), handling characters, Enter, cursor left/right, and Backspace, and clearing lines with CSI codes. Examples cover colored text, simple progress indicators, and a minimal command-line with syntax highlighting. The message: with a small set of codes you can implement powerful terminal interfaces, even without libraries.

Explores writing on Mount Hymettos over ~3,000 years, using Duplo/Lego to visualize place-centered writing. Summarizes 'Mount Hymettos, Athens: A Holy Place for Writing' and notes inscriptions from Zeus Semios’ sanctuary (7th c. BCE), including 'X wrote this' and alphabetic sequences, suggesting writing as ritual. Surveys graffiti from caves (Liontari, Vari) and monastic sites (Kaisariani, Agios Markos). Discusses monumental writing on stone and the idea of sema. Reports a Lego Serious Play session led by Helen Magowan that inspired scene-building. Encourages reading the published article and sharing Lego creations.

Found last year among Michigan-reel boxes, Méliès's 1897 short Gugusse et l'Automate, a 45-second film long thought lost, has been restored by the Library of Congress. The reel shows a child-sized robot clown who grows to adult size and attacks another clown before being smashed with a hammer, and is believed to be the earliest robot in cinema (the term 'robot' not used until 1921). Discovered by a donor's descendants, the fragile nitrate stock was rescued and identified by Méliès Star Film Company logo; more Méliès fragments were recovered. It can be viewed on LOC's site.

BrewDog has fallen into administration as Tilray buys its UK brewing operations, brand and 11 pubs for £33m. Tilray will also run BrewDog’s Ellon brewery and distribution hub, while 18 franchise bars will continue. The deal preserves 733 jobs but cuts 484 and closes 38 UK bars immediately. The German arm will be liquidated. Equity for Punks investors get no return, and small investors face losses, with about £75m raised from the scheme at risk. BrewDog had posted losses and limited profitability in recent years.

Bruin's Burak Karakan argues Go is the best language for AI agents. Benefits include compiled, strongly/statically typed code that yields safer generated code; a simple syntax compared to Rust; opinionated tooling and standard practices that simplify AI code generation; easy cross-platform binaries for testing and deployment; fast feedback loops and developer experience. Bruin uses Go for its CLI and plans to double down, believing Go's usability, performance, and ubiquity suit agent-driven software, though the future of languages remains open.

Apple reportedly has underutilized Private Cloud Compute, using about 10% capacity. Apple Intelligence features are not being used as expected. Bloomberg said Siri models could run on Google servers; The Information says Google is running Siri in its data centers, adhering to Apple privacy standards. Private Cloud Compute is underpowered; its chips (modified M2 Ultra) can’t run frontier models like Gemini. Apple’s cloud is fragmented, causing inefficiencies and costs, with unified infrastructure efforts stalling. As Siri demand grows, Apple is in advanced talks with Google to host Siri on Google Cloud; long-term plans may shift toward more in-house infrastructure.

This guide shows how to turn a Gleam project into a single executable since Gleam lacks native executables. Methods include: Erlang target with Gleescript (requires Erlang VM); Burrito to wrap BEAM into a self-contained binary (not yet tested with Gleam); JavaScript target with Deno compile plus bundling (esbuild) and deno compile; Node SEA (experimental) with bundling and binary injection; Bun build (compile + bundle) producing a single file with Bun runtime; and Nexe (Node) as another option. Bun is fastest and easiest, but bundling runtimes makes large executables (often >100 MB).

Go can't adopt try because the real obstacle is its error type, not boilerplate. Zig uses finite, compiler-known error sets with exhaustive checking and a path-trace; Go uses the opaque, flexible error interface, allowing arbitrary payloads via wrapping. Introducing try would be useless without redesigning the error system, which would break stdlib and millions of lines of code. The Go team’s stance isn’t just about readability—it’s that you can’t get Zig-like guarantees without a foundational rewrite, so if err != nil isn’t going anywhere.

An informal, exploratory meditation on fluid mechanics aimed at understanding how pressure gradients drive flow, acceleration, and the role of gravity. Through thought experiments with tanks, spouts, and narrowing pipes, the author grapples with mass conservation, velocity distribution across cross-sections, and the shape of pipes needed for steady, efficient flow. The piece raises questions about sideways pressure, equivelocity concepts, and whether steady-state flows can be characterized by pressure fields alone, ending with a taxonomy of static, constant-velocity, steady-state, and dynamic regimes.

Manuel Schipper outlines a lightweight setup to run 4–8 parallel coding agents using tmux, Markdown feature designs (FDs), and six slash commands. Each FD captures problem, explored solutions, implementation plan, and verification, and moves through a lifecycle from planning to verification/archiving. Roles include PM, Planner, and Worker across dedicated tmux windows; /fd-deep runs multiple agents in parallel for hard problems. A dev guide and CLAUDE.md improve context retention. He notes a practical limit around eight agents and provides /fd-init to bootstrap new repos.

Brent Simmons revisits Objective-C, recounting his push to drop it at Audible but confessing he still loved coding in it. For a fast blog generator, he explored Python, Swift, Rust, Go, and C, aiming to render a 25-year-old blog in under a second. He chose to lean toward speed but realized Objective-C, a small language built on C with nicer data modeling, fits nicely: its distinctive bracket syntax can seem odd, yet it’s easy to learn and unlikely to incur rapid tech debt. He plans to ship SalmonBay (open source on Codeberg) and keep experimenting with Objective-C.

Given n+1 distinct points (x_i, y_i), there is a unique polynomial p of degree ≤ n interpolating them. Use the Lagrange basis l_i(x)=∏_{j≠i}(x−x_j)/(x_i−x_j), with l_i(x_j)=δ_{ij}. The interpolant is p(x)=∑_{i=0}^n y_i l_i(x). This proves existence, gives deg ≤ n, and ensures uniqueness since any difference with another interpolant has more roots than its degree. The l_i form a basis for P_n(ℝ). In the Lagrange form, a_j=y_j, so the interpolation matrix is the identity in that basis; in the monomial basis, the Vandermonde matrix V has det(V)=∏_{i<j}(x_j−x_i), invertible for distinct x_i.
