100% Automated: How I Built a Self-Healing Price Scraper for 163 Shipping Providers

A solo engineer describes building a fully automated, self-healing price scraper for 163 European shipping providers using an agentic task graph. The system runs updater scripts per provider, detects failures, and dispatches AI agents (Claude Code CLI, OpenAI Codex CLI, Cursor) to diagnose broken scrapers, rewrite scripts, and verify prices against live carrier websites. Key design patterns include: a layered architecture separating the calculator, updater scripts, and agentic loop; pluggable LLM routing with fallbacks and cooldown handling for rate limits; deterministic pre-checks before invoking LLMs; and a two-agent verifier pattern where a second agent reviews the first's output cold. Feedback from failed verifications is written into the next agent's prompt as structured context. The post concludes with practical takeaways for engineers building agentic pipelines, including single-responsibility agents, independent verifiers, and model-to-task matching.

I turned an old Android phone into a home server, and it outperformed my Raspberry Pi

An old Android phone running Termux can serve as a capable home server that outperforms a Raspberry Pi in several ways. The phone's UFS storage is significantly faster than microSD cards commonly used in Pi setups, and even older flagship Android chips tend to be more powerful than typical SBC processors. Setup involves installing Termux, disabling battery optimization, and assigning a static IP. Services like Jellyfin, Tailscale, ad-blockers, file servers, and lightweight databases run well. The main caveat is battery longevity when kept plugged in constantly, which a smart plug can help manage.

My 3D printer pays for itself every time I skip buying a PC accessory

A home lab enthusiast shares how 3D printing has replaced buying small PC accessories. By printing custom cable organizers, headphone stands, GPU anti-sag risers, Raspberry Pi cases, and ESP32 enclosures, they get perfectly sized parts for under $5 that outperform cheap ready-made alternatives. The post covers practical use cases including PETG filament for heat-resistant functional parts and plans for future projects like DIY headphones and an open-air E-ATX server case.

Visualize radio signals with Raspberry Pi 5-based QuadRF 4x4 MIMO software-defined radio tile (Crowdfunding)

QuadRF là một thiết bị SDR 4x4 MIMO dựa trên Raspberry Pi 5 và FPGA Lattice ECP5, hoạt động như camera RF thời gian thực. Nó hiển thị tín hiệu radio 4,9–6,0 GHz dưới dạng lớp phủ AR 30 FPS trên iOS/Android/desktop, tương thích với GNU Radio, SoapySDR và ZeroMQ, mã nguồn mở GPLv2. Các module có thể ghép nối thành mảng phased array cho liên lạc EME, thiên văn vô tuyến, vệ tinh LEO và mạng mesh, khởi động crowdfunding 100.000 USD, giá từ 499 USD, dự kiến giao hàng vào tháng 9/2026.

Lập trình viên nên đọc bài này để khám phá cách kết hợp FPGA và Raspberry Pi 5 tạo ra một hệ thống định hướng sóng vô tuyến tiên tiến, giúp phát triển ứng dụng SDR (Software-Defined Radio) đa kênh MIMO hiệu quả cho các dự án nghiên cứu, phát triển phần mềm và ứng dụng thực tế như truyền thông vệ tinh, radar hoặc hệ thống truyền thông mesh.

The emergence of the web data infrastructure layer for AI

As AI systems move beyond static training data, enterprises face a growing need for real-time web data infrastructure. Traditional model training on fixed snapshots is insufficient for use cases like dynamic pricing, market tracking, and reducing hallucinations. A new infrastructure layer — capable of emulating human browsing at massive scale, navigating anti-bot protections, and delivering structured data with low latency — is emerging to fill this gap. Bright Data's CEO argues that AI intelligence without a live knowledge layer is practically useless, and that 97% of AI organizations depend on real-time web data yet 90% feel constrained by access restrictions. Compliance with GDPR and CCPA is addressed through consent-based networks and public-data-only policies. This sponsored content promotes Bright Data's web data platform as a solution.

Raspberry Pi Locator Website To Shut Down In July

Rpilocator.com, a popular site tracking Raspberry Pi stock and pricing across online retailers, is shutting down in July 2026. The main reason is that the site's indexing bot has been blocked by most shopping sites, likely due to anti-scraping measures aimed at AI bots. The site still serves around 11,000 monthly users but the effort to maintain workarounds became unsustainable. The closure also reflects a broader shift in the single-board computer landscape: the chip shortage era that made such a tracker essential has passed, replaced by concerns over rising memory prices pushing Raspberry Pi boards into luxury price territory.
