Show HN: Fortress – a stealth Chromium so your agents stop getting blocked

Fortress is an open-source Stealth Chromium engine that patches the browser engine (C++) to correct the fingerprint, exposing raw CDP on localhost:9222 so existing Playwright/Puppeteer scripts work unchanged. Detectors like CreepJS, Sannysoft, BrowserScan, and Cloudflare Turnstile see a stock Chrome, not a patched page. It requires only one line of code change to integrate. It ships as BSD-3 software with patches and build scripts, available as native Linux/Windows binaries or Docker images, with stable and latest Chromium options. It also provides Fortress MCP for AI agents with 29 tools to fetch/protect pages.

An interactive explorer for Benford's Law across real datasets

Benford's Law states that in many real-world data, the leading digit is not uniform but follows P(d)=log10(1+1/d), with 1 ≈30.1%, 2 ≈17.6%, …, 9 ≈4.6%. It holds across diverse data (river lengths, populations, prices, Fibonacci, powers of 2) and is scale-invariant. Origin: Newcomb (1881) and Benford (1938); Hill (1995) proved it for mixed distributions. Applications include fraud detection and data integrity checks; deviations signal anomalies but are not proof of manipulation. The article also presents eight datasets, a reproducible dataset explorer, and steps to compute first-digit distributions and MAD.

Tenda firmware (multiple versions) contains hidden authentication backdoor

Several Tenda firmware versions contain an undocumented backdoor in /bin/httpd/login() that bypasses authentication by directly comparing a stored password (GetValue('sys.rzadmin.password')) to user input; any username works for admin access (role=2). CVE-2026-11405. Affected: US_FH1201V1.0BR_V1.2.0.14(408)_EN_TD; US_W15EV1.0br_V15.11.0.5(1068_1567_841)_EN_TDE; US_AC10V1.0re_V15.03.06.46_multi_TDE01; US_AC5V1.0RTL_V15.03.06.48_multi_TDE01; US_AC6V2.0RTL_V15.03.06.51_multi_TDE01. Mitigations: disable remote management; restrict LAN exposure; change LAN IP. Vendor has not provided a statement.

We charge $10k a week to delete AI-generated code

Slopfix is a three‑engineer team that refactors AI-generated vibecoded codebases to maintainability. They offer a free initial analysis; if solvable, they quote a fixed price and a reduction target (e.g., 100,000 lines down to 35,000). They do one week of focused work, preceded by a written, screen‑by‑screen and endpoint checklist. They consolidate formatters, convert bespoke code to libraries, remove duplication, and rebuild what’s necessary. Deliverables: smaller codebase, QA checklist, CLAUDE.md, lint rules, CI checks, plus two weeks warranty. Cost: $10,000 for a week; payment scales with target hit. Contact [email protected].

IEEE Rolls Out Large Language Models Training Course

IEEE Spectrum reports on IEEE's online training program for large language models. As LLMs move from research to engineering, they reshape workflows and drive rising demand for expertise (markets ~33% yearly to 2030). Key shifts include API-based integration, reducing hallucinations via retrieval-augmented generation, securing data with private instances, and enhanced collaboration through automation. IEEE's five-course “Large Language Models Demystified” on the IEEE Learning Network covers evolution, transformer architecture, model design, PyTorch pipelines, optimization, RLHF, RAG, and deployment, awarding PD credits and a digital badge; organizations can arrange group enrollment.

Men's average testosterone levels have halved in last 50 years

Meta-analysis of six longitudinal studies (118,593 men from Israel, the US, Brazil, Finland and Denmark, 1972–2019) finds total testosterone declined about 54% over the past 50 years, accelerating after 2000. Obesity and metabolic syndrome likely explain part of the drop, but environmental factors—endocrine-disrupting chemicals and climate-related exposure—may also contribute. Experts warn of a male reproductive health crisis and call for precautionary reductions in chemical exposures; they also note that testosterone supplements can suppress sperm production and should not be seen as a quick fix.

Camera with transparent display launches for the equivalent of $29

Godox C100 is a tiny camera that uses a large transparent display as its viewfinder, showing battery, mode, and exposure with corner hints of the final image. It records stills and videos in 1:1, 3:2, 4:3, and 16:9, stores on microSD up to 128 GB, and transfers via USB-C. Weighing about 65 g, it omits Wi‑Fi and Bluetooth to cut costs. Priced at CNY 199 (about $29) in China, with no confirmed international launch; marketed also as a light meter for analog exposure.

Re: I'm Begging You to Leave Your AI Note-Taker at Home

Yes, actually, I do fucking mind argues against AI note-taking in casual meetings. The author recalls a physio asking to record medical status with an AI note-taker and says they mind, refusing or not wanting every word transcribed via cloud services. Real-time recording is described as creepy, invasive, and unnecessary in a coffee catch-up, with a call to leave devices off or use paper notes. The piece questions why ubiquitous note-taking is needed, urges asking “why” repeatedly to uncover motives, and emphasizes privacy over AI-driven documentation in everyday chats.

Herdr: One terminal to rule them all

Herdr is a terminal-based agent multiplexer: run multiple coding agents in one real terminal, on any box, with persistence across SSH disconnections. You can attach from a phone; it shows agent states (blocked/working/done/idle) in a sidebar, and you can reattach remotely. It provides a CLI and JSON API to manage workspaces, panes, and agent state; supports remote SSH attach, a mobile-friendly TUI, and a plugin marketplace of integrations. It stays inside your terminal—no GUI, no hosted control plane.

Decrypting View State Messages

An IIS post explains decrypting ASP.NET view states by turning autogen keys (1024-byte blobs stored in the registry/LSA) into final machine keys used for legacy and modern crypto. In legacy, the master validation key is the first 64 bytes and the master decryption key the next 24 bytes. In modern, the bytes derive via an HMAC-SHA512 SP800-108 process using two secondary purposes (IsolateApps and IsolateByAppId) and an optional ViewStateUserKey. To decrypt, base64-decode, strip the validation hash, validate, then decrypt; IV handling differs (zeros for legacy; extracted for modern). A VSRipper tool automates key derivation and decryption.

Show HN: Halo – open-source, tamper-evident runtime evidence for AI agents

halo-record provides tamper-evident, hash-chained runtime records for AI agents. It logs all agent actions (tool/model calls, data access, approvals) into an append-only, verifiable log. It requires zero runtime dependencies (standard library only); pip install halo-record; no network calls except optional witness. The package includes recorder, verifier, witness client, and report server, with redacted inputs. Completeness requires an external witness to anchor the chain, e.g. halo anchor. It supports adapters (OpenTelemetry, LangChain, Vercel AI SDK) and CLI tools (verify, report, serve, anchor, demo). Apache-2.0; aimed as evidence for SOC 2, EU AI Act, ISO/NIST.

Fixing analog audio on the $2.58 HDMI-to-VGA adapter

An ultra-cheap HDMI-to-VGA DAC used with a Switch produced loud crackling due to switching noise from the sigma-delta DAC. The author traced the issue to an NX3303X DAC inside, experimented with ground loops and filters, and found that the DAC’s ~600 Ω internal resistance plus the external RC network made filtering ineffective, with audible noise and jitter. A small ~5 nF cap was proposed, but the internal resistance dominated; further mods (DC blocking, channel swapping, heatsink) helped little. The author recommends better-sourced MX9291/2-based DACs or HDMI2SCART dongles for proper audio, rather than DIY filtering.
