Quadratic Micropass Type Inference

Quadratic Micropass Type Inference proposes a multi-pass, user-prioritized inference that reorders unifications to match developer expectations rather than code order. Inference runs through ordered passes (known_applications, known_assignments, known_return_types, known_same_as_unifications, known_record_fields, resolve_records, less_known_functions, default_numbers, default_unknown_to_unit_or_lift), re-running earlier passes after each step. Errors are generated by a separate type checker after inference. The approach aims to reduce misleading messages and better align with user intent, illustrated with examples and a proof-of-concept.

A forecast of the fair market value of SpaceX's businesses

Forecast for SpaceX’s June 2026 IPO values seven segments to about $1.253T; adding cash and subtracting debt yields ~\$1.250T equity, about 29% under a \$1.75T target. A bull-case (75th percentile) across segments reaches ~\$1.675T, near the target. Starlink (consumer/enterprise/direct-to-cell) dominates ~\$602B (34% of the IPO price). xAI at \$258B is highly speculative; Starship is pure option value (~\$170B); physical assets ~\$46B. The conclusion: the \$1.75T price hinges on everything going right and may warrant a conglomerate premium; retail demand could be strong.

Snow melt-off in American west stuns scientists

New measurements show western US snowpack collapsed after an unusually warm winter and record March heat. April surveys found Sierra Nevada SWE at 18% of average, Colorado River headwaters about 24%, Great Basin 16%, Rio Grande 8%. Snow acts as a natural water savings account; with melt accelerating, major basins like Lake Mead and Lake Powell risk critically low levels, potentially cutting off hydroelectricity and water deliveries. Even with possible storms, the melt is unlikely to be reversed this year. The drought also foreshadows an earlier, longer fire season.

Inference Engine for Apple Silicon

Onde Inference is an on-device LLM inference engine optimized for Apple Silicon. It runs entirely on the device, enabling live App Store apps with fully on-device chat—no server, low latency, and no data leaves the device. The project is in production and offers an SDK and a website.

Modern SQLite: Features You Didn't Know It Had

SQLite now includes built-in JSON support with a JSON extension to store and query JSON data, enabling flexible schemas and json_extract queries, plus indexing on JSON expressions. The FTS5 extension adds full-text search with ranking and phrase/prefix queries, all inside SQLite. Analytics are enhanced by common table expressions (CTEs) and window functions for running totals and dashboards. STRICT tables enforce stricter typing at insert time. Generated columns store derived data (e.g., full_name) and can be indexed. Write-ahead logging (WAL) improves concurrency, letting reads and writes run concurrently.

EmDash: A Fresh Take on CMS

EmDash is a real, open‑source CMS built on TypeScript and Astro 6.0. It runs serverless on Cloudflare Workers (SQLite locally, Cloudflare D1 in production) and stores content as portable JSON (structured text) rather than HTML. It’s pitched as a modern WordPress rebuilt from scratch, with sandboxed plugins and AI agents as first‑class users. The admin evokes a TinyMCE feel and uses Astro themes, avoiding Gutenberg-like block editing. For personal blogs, the author prefers Markdown/static sites; EmDash is early, developer‑oriented, and worth watching despite costs and trade‑offs.

Google releases Gemma 4 open models

Gemma 4 is DeepMind’s most capable open-family model built from Gemini 3 tech, designed for agentic workflows, multimodal reasoning, and offline edge deployment. It supports 140 languages, fine-tuning, and runs on local hardware (E2B/E4B) with 26B and 31B variants for frontier intelligence on PCs. Prioritizing safety with enterprise-grade security and transparent deployment, the Gemini/Gemma line includes Gemini, Genie, Lyria, Veo, and Gemma Nano Banana, plus developer tools like Google AI Studio and Edge Gallery.

Renewables reached nearly 50% of global electricity capacity last year

IRENA’s 2026 Renewable Capacity Statistics show renewables reached 49.4% of global installed electricity capacity in 2025, with a 15.5% YoY expansion after adding 692 GW, led by solar (about three-quarters of new capacity). Renewables accounted for 85.6% of global capacity additions in 2025 (down from 92% in 2024), while non-renewables rebounded, notably coal in China and gas in the US. COP28’s 11 TW by 2030 target appears unlikely given renewables are around 5.15 TW end-2025. Decentralised, diversified energy improves resilience.

Artemis computer running two instances of MS outlook; they can't figure out why

A Bluesky post explains that Bluesky is a highly interactive web app requiring JavaScript. It also humorously describes astronauts calling Houston because the spaceship computer is running two Outlook instances, with NASA about to remote in. 2026-04-02T06:06:54.854Z

Artemis II will use laser beams to live-stream 4K moon footage at 260 Mbps

Artemis II will use NASA’s laser-based Orion Artemis II Optical Communications (O2O) system to beam 4K lunar footage at up to 260 Mbps from the Moon to Earth, with Nikon cameras capturing the far side. Ground stations in Las Cruces, NM, and Table Mountain, CA, support the link, while traditional Deep Space Network radio remains a backup. A 41-minute 'dark window' can interrupt laser and DSN links. NASA has demonstrated higher speeds in other tests (622 Mbps previously; up to 200 Gbps in near-Earth tests).

Delve allegedly forked an open-source tool and sold it as its own

TechCrunch reports that YC-backed compliance startup Delve faces new backlash after an anonymous whistleblower, DeepDelver, alleged Delve repackaged an open-source tool as its own. The tool Pathways allegedly mirrors Sim.ai’s SimStudio, potentially violating Apache licensing due to missing attribution. Sim.ai’s Emir Karabeg says Delve never had a license with Sim.ai, and that Sim.ai had previously paid Delve as a customer. Delve denies the data-faking allegations; the firm’s funding round and due diligence by Insight Partners are also in focus, while Delve has not commented.

Show HN: I built a DNS resolver from scratch in Rust – no DNS libraries

numa is a portable DNS resolver in Rust that runs as a single ~8MB binary, blocks ads on any network, and hosts local domains (e.g., frontend.numa) with auto-revert hostname overrides. It supports forward, recursive, or auto DNS resolution with optional DNSSEC validation and built-in DoH fallback. Features include mDNS LAN discovery, path-based routing, and a web dashboard. Shipped as a system service on macOS/Linux and auto-starts on Windows. Installation commands are provided for all platforms.

Emacs-libgterm: Terminal emulator for Emacs using libghostty-vt

emacs-libgterm is a Terminal emulator for Emacs built on Ghostty's libghostty-vt. It mirrors emacs-libvterm’s architecture but uses Ghostty's engine, offering SIMD VT escape parsing, improved Unicode/grapheme handling, text reflow on resize, Kitty graphics protocol, and active development. An early prototype tested on macOS Apple Silicon. Requires Emacs 25.1+, Zig 0.15.2+, Git. Install via use-package with straight, vc, or quelpa, or by local clone; on first load it clones Ghostty and compiles the Zig module. Usage: M-x gterm. Customizable: shell, TERM, auto-compile, mouse scroll. Known issues: width mismatches with certain glyphs; no mouse support. GPL-3.0.

LinkedIn Is Illegally Searching Your Computer

BrowserGate, a Fairlinked e.V. campaign, claims LinkedIn secretly scans users' computers via hidden code as they visit linkedin.com, collecting identified individuals' data (religious beliefs, political opinions, disabilities, job-search activity) and sending it to LinkedIn and third parties, including HUMAN Security and Google scripts, without consent. The group says this constitutes mass personal data breaches, corporate espionage against competitors, and deception of EU regulators under the Digital Markets Act. They seek public support and funding for legal action to halt the practices and document the alleged crimes.
