Show HN: GNU Grep as a PHP Extension

Ext-gnu-grep is a GitHub project that builds a native PHP extension (grep.so) by vendoring GNU grep and wrapping it with a PHP interface rather than a CLI wrapper. Implemented in C, the extension exposes GNUGrep\Engine, GNUGrep\Pattern, and ggrep() for GNU grep-style searches on strings or buffers. It ships with a real PHP extension skeleton (config.m4, php_grep.c/h, tests, vendor/grep) and mirrors many GNU grep options (-G/-E/-F, -i/-v/-w/-x, recursive modes, binary handling, -n/-c/-l/-o, etc.). Licensing follows GPLv3+. Build/tests include PHPT suite and comparison tools against upstream GNU grep.

Kalshi CEO expects US DOJ to prosecute insider trading cases

Kalshi CEO Tarek Mansour says he expects the U.S. DOJ to prosecute insider trading on prediction markets like Kalshi, calling such activity a federal crime and stating prosecutors will pursue cases. He advocates banning insider trading with penalties up to criminal prosecution and supports a federal consumer-protection framework for prediction markets rather than a patchwork state approach, noting ongoing probes and a federal suit challenging state regulation.

CPUs Aren't Dead. Gemma2B Out Scored GPT-3.5 Turbo on Test That Made It Famous

SeqPU reports Gemma 4 E2B-it (2B params) running on a laptop CPU matches GPT-3.5 Turbo on MT-Bench (~8.0 vs 7.94) without GPUs, via a raw model plus surgical guardrails. Seven concrete failure classes were identified; ~60-line fixes (arithmetic guards, a solver, per‑requirement verifier, regex passes) raise the score to ~8.2, approaching GPT-4 on some tasks. It runs offline on 4 GB weights, cost-free locally; Cloudflare/Oracle hosting can cost $0–$5/mo. The message: the field's compute gap is solvable by software engineering; open‑source local inference is production-ready on consumer hardware.

Google Broke Its Promise to Me. Now ICE Has My Data

EFF details how Google handed over Amandla Thomas-Johnson’s data to ICE in 2025 after an administrative subpoena, despite Google’s promise to notify users before responding to law-enforcement requests. Thomas-Johnson, a PhD student who briefly protested pro-Palestinian views, faced investigations and travel concerns after the disclosure. EFF has asked California and New York AGs to probe Google for deceptive trade practices. The piece argues that private data plus state power enables invasive surveillance and creates accountability gaps.

AI-Assisted Cognition Endangers Human Development

The article warns that AI-assisted cognition risks slowing human development via cognitive skew and reduced idea diversity. It explains cognition and how AI base models remain static, misaligning with new events, leading to a “cognitive inbreeding” where population-level thinking collapses to a few base-model patterns. It introduces the Dynamic Dialectic Substrate as the dynamic reservoir of human ideas that evolves through dialectic processes, arguing AI can endanger this substrate if used indiscriminately. The piece proposes “cognition hygiene”: rely on human discussion, diversify AI tools, avoid nudging, use search, different AI personas. It notes high uncertainty and calls for research.

Where the Heck Did My Taxes Go?

A 400 Bad Request page says the request was blocked by the server's security policies; if this is an error, contact support.

The tiniest e-reader in the world, and you can build one yourself

Paul Lagier built a pocket-sized e-reader with a 3D-printed shell, ESP32 and Heltec Wireless Paper display. Roughly the size of a car key fob, it costs about $30 in parts and reads plain TXT files (not PDFs/EPUBs). With 8MB storage it can hold about six to ten 300-page books. The project’s updates add a refined shell, firmware tweaks, a web interface for syncing bookmarks, folders, a customizable screensaver, more languages, and better power efficiency; a new lists feature supports to-do items. Files are on Ko‑Fi for ~€4.90 (~$5.80).

Fix monitor that goes black, off or blinks due to static electricity in chair

A home-office issue where static electricity from a chair causes a monitor to go black or blink due to EMI spikes on video cables. Grounding the chair (attach a metal chain to the floor) greatly reduces shocks; adding ferrite rings to video cables further mitigates EMI, especially with DisplayPort cables and certain adapters. The problem isn’t fully solved—standing up quickly still blips, but slower movement helps. The post cites DisplayLink white papers and online discussions for context.

Adaptional (YC S25) Is Hiring Founding AI Engineers

Office in the Presidio; compensation includes competitive cash and equity.

Show HN: Libretto – Making AI browser automations deterministic

Libretto is an open-source AI toolkit from Saffron Health for building and maintaining browser automations. It gives a coding agent a live browser, a token-efficient CLI, and tools to inspect pages, capture network traffic, record/replay user actions as scripts, and debug workflows against real sites. It supports CLI commands (setup, status, open, snapshot, exec, run, resume, save, close, ai configure) and stores state in .libretto under the project. Credentials pull from env vars (OpenAI, Anthropic, Gemini, Vertex).

How do Wake-On-LAN works

Wake-on-LAN wakes a PC via a Magic Packet that a network interface card with WoL enabled listens for. The packet starts with six 0xFF bytes, then the target MAC repeated 16 times (optionally a password). It’s usually sent as a UDP datagram to the broadcast IP (IPv4 255.255.255.255; port 9 common). Limitations: must be on the same LAN/VLAN, requires MAC, not guaranteed receipt, and doesn’t work over Wi‑Fi. The post also shows a Golang implementation: CreateMagicPacket validates and formats the MAC, then SendMagicPacket validates IP and sends via UDP.

Anna's Archive Loses $322M Spotify Piracy Case Without a Fight

Major labels and Spotify won a $322 million default judgment against Anna’s Archive for Spotify-related piracy, with the site failing to appear in court. Judge Jed Rakoff awarded statutory damages ($150,000) for several works plus a $2,500 DMCA claim for 120,000 files, totaling $322.2 million. A permanent worldwide injunction bars ten Anna’s Archive domains and orders registries, hosts, and others to suspend domains, disable nameservers, and preserve evidence. The operator remains unidentified, and recovery and enforcement are uncertain.

New Modern Greek

An experiment proposing a New Modern Greek alphabet to simplify orthography. Since the last major revision in 1982, it suggests turning digraphs into single letters and removing spelling distinctions that encode gender, number, and conjugation. Key changes: αι dropped; ει, οι, υι, η, υ all /i/ ; ου gets its own letter (Ȣ/ȣ); ντ (/d/) and μπ (/b/) become single letters; uppercase uses Cyrillic Б to avoid Β confusion; γκ/γγ (/ɡ/) become one letter; σ, ς unify as ϲ; ω merges with ο. Aimed at making future revision more consistent.

Study: Back-to-basics approach can match or outperform AI in language analysis

A University of Manchester study shows a grammar-based method, LambdaG, can match or beat advanced AI in authorship analysis. LambdaG analyzes grammar, function-word use, sentence structure, and punctuation to build a transparent writer signature with lower computational cost. Tested on 12 real-world datasets (emails, forums, reviews), it often outperformed neural-network models. The approach argues for linguistically grounded methods over bigger AI without sacrificing accuracy. Potential applications include forensic linguistics, criminal investigations, online abuse detection, and academic integrity monitoring. Published in Humanities and Social Sciences Communications.

Elevated errors on Claude.ai, API, Claude Code

Claude Status shows ongoing outages across Claude AI, the Claude API, and Claude Code. On Apr 15, 2026 the API fully recovered (8:01 PT / 16:01 UTC), but Claude AI remains error-prone and login remains broken for Claude Code. The feed records repeated outages—OAuth and login failures, 500/503 errors, and degraded web/API performance—with ongoing mitigation and monitoring after a string of incidents dating back to early April 2026.

The Deepfake Nudes Crisis in Schools Is Worse Than You Thought

WIRED and Indicator found about 90 schools and 600 students worldwide affected by AI-generated deepfake nude images, often created by teenage boys who alter classmates' photos and share them via social apps. The phenomenon, boosted by accessible nudification tools, is considered child sexual abuse material and has prompted mixed school and law-enforcement responses. Cases span 28+ countries; UNICEF and Thorn warn the true scale is higher. Experts urge better prevention, digital forensics, and policy, including rapid takedown laws; some places are banning nudification apps.

Show HN: Pseudonymizing sensitive data for LLMs without losing context

Built a context-aware token proxy to pseudonymize sensitive data before sending to Claude for AI SOC triage. Naive regex caused syntactic hallucinations and entity fragmentation; V2 added spaCy NER and structured pseudonyms; V3 adds context-preserving pseudonymization with ASN-aware IP replacement and internal/partner/external classification, with optional domain masking. Addressed false positives via dotted-property detection, skiplists, and allowlists; added tail-buffering for streaming. It’s a safety net, not a guarantee. Open-sourced the proxy and deployment steps (Docker, config.json), with provider-agnostic design. Useful for other frontier-model scenarios.
