I built the fastest PHP webserver in the world

Qbix Server is a pure-PHP web server designed to replace Nginx/FPM/Node/Redis/Docker. It loads your app once, then forks many workers via copy-on-write, achieving high concurrency with small memory (about 120 KB per worker; ~47 MB total for 400 workers on 200 MB). It runs unmodified PHP apps (WordPress, Laravel, Symfony, Drupal) and supports WebSocket rooms, microservice isolation, cluster replication with SQLite, and six example apps. It ships as a single PHP file or a self-contained binary, includes auto-generated API docs, TLS, cron, and a built-in dashboard at /Q/dashboard. Benchmarks claim 14x–24x throughput vs PHP-FPM/Swoole in various workloads.

Learning Another Language May Be One of the Best Ways to Keep Your Brain Healthy

Learning another language is a complex cognitive activity that engages memory, sound discrimination, pattern recognition, grammar, and real-time retrieval. Neuroplastic changes in gray and white matter accompany language experience, contributing to cognitive reserve that can bolster function in aging and may delay dementia symptoms, though it does not prevent disease. Adults can learn languages throughout life, though strengths differ: kids excel at pronunciation; adults leverage vocabulary and strategies. Benefits include social connection and cultural understanding. There’s no fixed practice, but sustained, challenging language learning—via study or apps—may boost cognitive resilience with age.

Black Holes or Black Hole Stars? Astronomers Spar over 'Little Red Dots'

Quanta reports on James Webb’s “little red dots”—tiny, bright red sources in the early universe that sparked a debate about their nature. Early spectra hinted at supermassive black holes; in 2025 two dots suggested a new object: a black hole star—a huge hydrogen shell powered by a central black hole, emitting a Balmer break and masking X-rays. Others argue for standard black holes with redness explained by gas, dust, or electron scattering. The quasi-star idea has resurfaced. Some evidence points to a puberty-like phase as dots fade with cosmic age. The debate remains polarized and unresolved.

A graphical desktop for the ZX Spectrum

ZX Desk is a GUI desktop for the 48K ZX Spectrum, written in Z80 assembly. It provides overlapped, z-ordered windows, menus, a notepad, clock/calendar, a two-pane file manager, and a settings panel with a swappable RAM disk and storage backends; it runs on real hardware (not just an emulator) via esxDOS. The README details its architecture (device layer, frame discipline, event queue, hit testing, damage surfaces), build/run workflow (build.sh/run.sh, pasmo), and extensive measured optimizations that yield around 50 Hz framing. It also covers bugs, testing discipline, known gaps, and notes a ZX Desk Next variant in a separate repo.

Tin: full-text search for Postgres

PlanetScale announces TIN, a fast full-text search extension for Postgres and Neki (GA). TIN supports Boolean, phrase, and span queries, fuzzy/wildcard matching, and BM25 top-k, all with MVCC visibility. It uses Postgres ctid as 48-bit document identifiers and page/offset bitmaps, enabling vectorized intersections and fast heap access. In benchmarks, TIN vastly outperforms ParadeDB, pg_textsearch, and Postgres GIN across conjunction, disjunction, and phrase workloads, even with concurrent updates. It avoids segment renumbering during merges. Install with CREATE INDEX ... USING tin(...).

What Zig felt like, coming from Rust

After 7 years in Rust, the author experiments with Zig by reimplementing JSONPath (zig-jsonpath). IDE support is minimal, pushing the project toward CLI, with build.zig workflows. Zig favours a flat structure and, for testing, relies on explicit memory management; allocators and init/deinit are everywhere. Functional-style Rust patterns clash with Zig’s in-place mutation, though sum types exist. The example highlights Rust’s automatic Drop vs Zig’s manual memory handling (leak, double-free, orphaned allocations). The Zig ecosystem is young; core libraries and Unicode support lag. Overall: Zig is fast and modern, a plausible C successor, but still incomplete.

Ray Ozzie and the Optimism of Being Early

Ray Ozzie’s career traces the dawn of personal and collaborative computing. From PLATO’s online communities to building Lotus Notes, he pursued a future where distributed, user-built collaboration could scale across OS/2, Windows, Unix, Mac, and NT. Resources were tight, so the team focused on getting a usable match between people and technology rather than polish, shipping a versatile tool that could become CRM, help desk, or document collaboration. Notes polarized opinion and never became a universal standard, but it helped seed a democratized approach to software. Ozzie remains optimistic about AI/LLMs and renewed, user-built innovation.

Show HN: I wrote a custom assembler for CHIP-8 in C++

A GitHub repo for Tackx's c8-ass, a work-in-progress custom assembler for a CHIP-8 emulator. It includes src, docs, and examples, with a README outlining TODOs (validations, error handling, tests, INCBIN directive) and notes on live development streams.

Laya the open source version of Jev

ConvAI Innovations’ Laya is a 100+ language, open-source System 1 decision engine that outputs calibrated probabilities rather than text. Using bidirectional encoders and RLCD, it performs three primitives—choice, score, noul—in a single forward pass and runs about 32.8 ms on one GPU (7.2 ms per question) with sub-35 ms latency. It features three bundled checkpoints (backbone, multilingual, typed-decisions) in a single Hugging Face hub, plus a Router that detects scripts and routes to the appropriate model in under 1 ms. Compared with TypeSafe Jev, Laya offers better calibration, speed, and zero-cost self-hosted deployment across 51 languages and 9 workflows.

From Stonemasons to Carpenters

Michael Hilton argues AI-driven code generation shifts software from a stonemason model to a carpenter one: developers build the forms—tests, docs, guardrails—that enable code to be generated. This makes every developer a Product Manager who asks what to build, not just how. Software engineering becomes designing and validating complete systems, with faster feedback from immediate code generation shrinking the OODA loop. The analogy has limits, since software can be regenerated unlike poured concrete. Overall, engineers must elevate system-level design for AI-enabled software.

AI-generated posters don’t have to be horrible

AI-generated posters don’t have to be repetitive identikit images. The author experimented with ChatGPT to produce posters for a spring fayre in many distinct design aesthetics, not just the default craft-fair look. After initial attempts, they guide the model to styles like Bauhaus/modernist, Swiss, risograph, cut-paper, brutalist, Memphis, Japanese minimal, wayfinding, and more, and even explore combinations (e.g., Designers Republic, 90s rave, punk zine). The point is to avoid sameness and to keep text editable; AI can output HTML, PNG, or PDFs with real text. Inspired, they compiled a catalog of 100 poster styles with prompts and examples.

"The Secret Life of Circuits" is here

The Secret Life of Circuits by lcamtuf is now available as a premium hardcover with full-color illustrations; direct orders ship from No Starch and it’s also on Barnes & Noble and Amazon, shipping in October. The book offers practical electronics guidance for designing your own circuits and solving modern problems without heavy calculus, featuring careful design and nearly 300 diagrams and illustrations. Sample chapter and related blog posts are linked. Endorsements come from Travis Goodspeed, Eric Schlaepfer, Colin O’Flynn, and Chris Gammell, plus a humorous Hacker News quip about the fonts.

Suppress vulnerabilities applying Kubernetes context to scans

Vex8s generates VEX documents by correlating container vulnerabilities with Kubernetes settings to determine whether CVEs are exploitable in a cluster. It classifies CVEs into CWE-based vulnerability classes and predicts exploitation categories with an embedded ONNX model or Gemini LLM; each category maps to Kubernetes mitigations. By parsing a Kubernetes manifest, it checks if the mitigations are in place and, if so, adds the CVE to the VEX. Usage: passive mode (process existing Trivy/Grype reports) or active mode (scan images). Install via binary or make; Gemini mode requires GEMINI_API_KEY.

Stepfun Step 5 Preview (LLM): On AA Pareto frontier

Step 5 Preview is a proprietary multimodal model from StepFun (released Sept 18, 2026). It accepts text and image inputs, outputs text, and runs with a 1M-token context window. With 600B parameters, it ranks 44 on the Artificial Analysis Intelligence Index (high, above median 25). It produced 160M output tokens (more verbose than median 90M). Pricing: $1.00 per 1M input tokens and $2.70 per 1M output tokens (blended ~$0.51/1M tokens with cache). Not open source; API available via one provider. Total Intelligence Index evaluation cost: $918.34.

Veronese's Dogs

Thomas W. Laqueur argues Veronese’s dogs are essential, not decoration, in his theatrical canvases. Reading Cupid with Two Dogs, Happy Union, The Adoration of the Magi, and The Wedding Feast at Cana, he shows dogs shaping gaze, tenderness, and grounding grand scenes in the earthly present. The 1573 Inquisition over Christ in the House of Levi reveals Veronese’s theatricality in religious painting, leading to a label change rather than erasure. Across these works, dogs act as witnesses linking humans to the divine, even as Napoleon later looted The Wedding Feast.

If math is more than proof, we need to better celebrate the rest of it

Grant Sanderson's guest post, via Terence Tao, argues that mathematics should value 'motivated explanations'—narratives that explain how to think and why a result is right, not just produce proofs. Definitions may come in the middle; ideas can start imperfectly and be refined; exemplars include discovery fiction and the Princeton Companion to Mathematics. The piece proposes open exposition problems, new standards, and journals to credit explanatory work, and suggests career and funding shifts to reward expository contributions. It highlights examples from Thurston and Chow, and discusses AI-assisted progress on Erdős problems to show the need for human-understanding work.

GPT-6 Astra Solves a WWI German Radio Cipher

GPT-6 Astra cracked a WWI German ADFGVX cipher that had stumped others. The post explains ADFGVX encoding, with examples like HOUSE and PRINZ. Astra used the key TRUPPENVERSCHIEBUNG (rearranged alphabetically) and a long grid procedure to decode the November 27, 1918 message. The plaintext reportedly says an English cruiser arrived at Sevastopol and an Allied squadron would follow on the 26th; Astra notes a date mismatch and corroborates with HMS Canterbury logs, presenting this as a new decode.
