Shantell Sans is an open-source, variable font by ArrowType based on Shantell Martin’s handwriting, designed to be friendly, readable, and usable across contexts. It blends playful, handwritten character with professional metrics, inspired by Comic Sans but expanded with multiple axes: Weight, Italic, Informality, Bounce, and Spacing (and later Cyrillic support). Released under OFL and distributed via Google Fonts and GitHub, it includes Latin+Cyrillic glyph sets (380+ languages) and OpenType features. It aims for everyday appeal, wide accessibility, and animation-ready displays. It has been used by Whitney Museum shop, Cash App, tldraw, and univer.se.

Article argues for centralizing Rust error handling with a single AppError enum to replace scattered error types (sqlx::Error, reqwest::Error, etc.). It demonstrates using map_err to intercept and wrap foreign errors into AppError (with logging) before ? propagates, and using impl From<IOError> for AppError so the compiler auto-converts errors. This yields a cohesive, boilerplate-free design without heavy macro crates, providing one contract (Result<T, AppError>) across modules. Concludes it's transformative for Rust services; credits peer 'Joban' for inspiration.

Microsoft plans to put Office 2019/2021 for Mac into view-only mode on July 13, 2026 after a licensing certificate expires. Office 2019 ended support in 2023; Microsoft had previously said apps would continue to function. After expiry, affected apps can only open/view files and cannot edit or save. Office 2021 for Mac and Microsoft 365 for Mac on macOS 12+ can avoid this by updating to build 16.83; Office 2019 has no update path. Microsoft offers continue in view-only, switch to web apps, or buy/subscription. Reactions include concerns and migration suggestions.

The article explains why a 90% CI for the mean using ŝ and a normal 1.645 multiplier is too narrow when sigma is unknown. Gosset (Student) introduced the t-distribution and sample-size–dependent correction factors to widen intervals. For 90% CIs with n=2–20, factors are about 4, 2, 1.5, 1.3, 1.2, 1.1; beyond 20 use the naive ŝ. To get a 90% CI: ŝ × factor × 1.645. Example: n=7, mean 32, s=8 → 32 ± 8×1.2×1.645. Two-sample case uses (high−low)/√2 and a factor ~1.3.

Researchers say federal funding delays are irreparably harming science. Even after some restoration, NIH funds have not reached researchers, with labs emptied after terminations, staff laid off, and years of progress lost. In 2025, the Trump administration terminated many grants; in 2026, despite fiscal recovery on paper, NIH issued about half as many new grants as last year and shifted to fewer grants with longer timelines. Forecasts sit open or unpublished, eroding trust in NIH. Scientists like Sean Eddy and Rachael Sirianni warn that critical work, including pediatric cancer research, is stalling, delaying therapies and harming families.

Interface design feels great when it’s invisible and guides users naturally; many small, deliberate details matter. In a world where AI makes replication easy, Interfaces emphasizes exceptional craft and intent. The magazine, by Jakub Krehel (Interfere), covers animation, typography, layout, color, and more, often via interactive demos with source code. Subscriptions provide full access to all issues, a resource library, tools, agent skills, a private Discord community, and monthly new issues (launched with three initial issues). Prices: $7.99/mo or $79.99/yr.

tsplat renders Gaussian splats in your terminal, CPU-only, using Unicode blocks or graphics protocols. It’s a Rust project that works over SSH and requires no GPU. Install via cargo install --git or clone and build. It uses INRIA 3DGS .ply scenes (garden example) for testing. The render pipeline: project 3D splats into view, compute 2D covariance, bounding boxes, depth-sort, tile-based binning, and painter’s algorithm alpha-blending per pixel. Optimizations include fast exponential, row pruning, and rayon-based parallelism. MIT license.

WolfCOSE is a lightweight C library implementing CBOR (RFC 8949) and COSE (RFC 9052/9053) with wolfSSL as crypto backend. It offers post-quantum signing (ML-DSA) and FIPS 140-3 via wolfCrypt, MISRA C compliance, and DO-178 readiness for embedded systems. It supports all COSE message types (Sign1, Sign, Encrypt0/Encrypt, Mac0/Mac) with single- and multi-signer/recipient flows, 40 algorithms across signing, encryption, MAC, and key distribution. Footprint is tiny (7.5 KB text; 25.6 KB full); zero dynamic allocation. Build configurations: minimal, PQC, full; tests and examples; GPLv3.

Meta is reportedly developing an AI-powered pendant to test in the coming year, per a memo seen by The Information. The device would extend work from Limitless, the AI pendant startup Meta acquired in late 2025 that aimed to record conversations. Meta says the acquisition would accelerate AI-enabled wearables. The memo also mentions plans to expand AI glasses and launch a business subscription called Wearables for Work. The push appears aimed at reviving Reality Labs, which lost about $4 billion in Q1. TechCrunch has requested comment from Meta.

Shakespeare’s World details a map project to study Shakespeare’s places and how he imagined the world. The author teamed with Professor Gavin Hollis on ‘mapp’ry,’ downloaded Project Gutenberg texts, used spaCy NER to pull 578 place candidates, and manually curated 288 places, geocoding them with OpenCage and adjusting for ancient locations. They extracted 2,685 quotes and 153 scene settings across 38 plays and 288 places, then built interactive maps with MapLibre and Stadia Maps (Stamen Watercolour). Initial quill markers were replaced with circles/teardrops. Data glitches required Python scripts and manual fixes; readers can filter by play/place and contribute corrections.

Oxide describes debugging a disappearing Service Processor (SP) in their rack. The SP would vanish from the management network, leaving engineers with little insight. After ruling out CPU power issues, they traced the problem to the Cortex-M7 STM32H7, FPGA timing, and especially the FMC memory bus. A mismatch between the FMC’s memory attributes and the kernel’s default address map allowed cached writes to the FMC from unprivileged tasks, causing stalls. Changing the FMC base address to a non-cached device memory region fixed the issue; they stress transparency and better vendor docs.

Dusklight is a classic adventure now available for PC and mobile, with fixes and improvements. It supports cross-platform play via the Aurora compatibility layer (Windows, Linux, macOS, iOS, Android) and runs at higher resolutions and frame rates. The game offers flexible quality-of-life options for authentic or modern play. It’s brought to life by the inhabitants of the Twilit Realm. Note: running Dusklight requires a dump of your own original game copy.

It includes native Spark integration and a PySpark bridge, with Rust and Python tooling. The repo provides a Quick Start, examples for writing/reading Kore files, and documentation for building and testing. Current release: v0.1.0; repository contains Rust/Python components and a README with usage notes.

Agentic AI decouples coding from domain understanding. Software used to rely on building a mental domain model; now code can be generated without it, shifting the bottleneck to judging correctness. Domain experts can spot wrong outputs even if they can’t read code; engineers can build systems but may not recognize subtle errors in domain logic. The traditional path—engineer learning the domain—shrinks, while domain expertise remains scarce. The most valuable people mix both: they verify generated code and validate domain rules, writing tests that encode the true constraints. Deep domain models are the new moat.

Through a street encounter, the author argues that people constantly emit emotional signals—facial cues, tone, body signals—that others read and react to. He suggests corporations increasingly collect these emotional data points to infer feelings. The anecdote of a tense passerby who calmed after a friendly remark illustrates how social signals can change outcomes. The piece concludes by urging readers to observe their own sensations and emotions, noting that the belief these signals should be hidden is changing as companies mine them for insight.

Jef Raskin founded Apple’s Macintosh project and championed a simple, all‑in‑one, graphical interface designed to put people first. In this interview, he criticizes today’s Mac for complexity and bloat, discusses his later work on the Canon Cat and The Humane Environment, and argues for interface-centric design that becomes invisible to users. He reflects on his influence on computing, his preference for intuitive input devices, and his belief that real progress lies in easier, more accessible software rather than raw power. He died in 2005.
