New in NetBox Validation: A HIPAA Security Rule Compliance Pack

The Hot Fix

A tech support worker responds to a ticket about a printer in HR printing gibberish instead of documents. Upon arrival, he finds a manager using a hair dryer on the printer, which he defuses diplomatically. After basic troubleshooting fails, the team discovers the printer is outputting anonymous HR complaints submitted through a supposedly decommissioned intranet system, leading them to trace the network source of the misdirected print jobs.

Your router's "smart" connections are quietly making your Wi-Fi speeds worse, and the fix is easier than you think

Many routers broadcast all Wi-Fi bands (2.4GHz, 5GHz, 6GHz) under a single unified SSID using 'Smart Connect', which can cause devices to connect to slower bands without the user's knowledge or control. The recommended fix is to split the bands into separate SSIDs with distinct names, giving you explicit control over which devices connect to which band. This helps ensure performance-hungry devices stay on 5GHz, while IoT devices remain on 2.4GHz without congesting the faster band. Splitting SSIDs also makes network issues easier to diagnose, such as spotting when a specific band goes down.

Irish court tells regulator to reconsider TikTok’s China data-transfer ban

Tòa án tối cao Ireland giữ nguyên phạt 530 triệu euro cho TikTok vì chuyển dữ liệu người dùng châu Âu sang Trung Quốc vi phạm GDPR, nhưng yêu cầu cơ quan quản lý xem xét lại lệnh cấm chuyển dữ liệu trong tương lai để tạo điều kiện hoạt động cho TikTok. Vụ việc làm nổi bật căng thẳng giữa vai trò "thiên đường công nghệ" và trách nhiệm quản lý của Ireland trong bối cảnh nhiệm kỳ Chủ tịch Hội đồng EU mới.

Một lập trình viên cần đọc bài này để hiểu rõ cách GDPR và các quy định bảo mật dữ liệu ảnh hưởng đến thiết kế hệ thống xử lý dữ liệu quốc tế, đặc biệt khi phải đối mặt với các vấn đề về chuyển dữ liệu sang nước ngoài như trong trường hợp TikTok.

Building a passive Ethernet tap · Ata Kuyumcu's Blog

A DIY passive Ethernet tap built on mini breadboards using RJ45 breakout boards with screw terminals, inspired by the commercial Throwing Star LAN Tap. The device sits inline between a computer and router, copying signals to two monitor-only ports without injecting traffic. Two 220 pF capacitors force 100 Mbps negotiation so only two wire pairs are used, matching what the tap monitors. The build cost roughly €10 and successfully captured 2,769 packets from a smart TV in 7.5 minutes, revealing frequent SSDP NOTIFY broadcasts, mDNS announcements, and IGMP traffic — all with zero CRC errors.

South Africa’s fibre underdogs are beating the giants

The Internet Service Providers' Association (Ispa) of South Africa released its February 2026 FNO Perception Survey, where ISPs rate the fibre network operators they buy wholesale access from. Six smaller operators — Lightspeed, Open Fibre, Lightstruck, Evotel, Seacom FibreCo, and WeCom — scored between 6.6 and 7.1 out of 10, outperforming most of the eight largest networks. Octotel retained the top spot among the major players at 7.5, while Vumatel showed the biggest year-on-year improvement (+1.0). The survey covered 406 ratings from 45 ISPs across 11 metrics including reliability, technical proficiency, and open-access adherence. Ispa notes the smaller operators' strong results are promising but carry less statistical weight due to fewer raters.

NIH unveils world's largest genomics-health database

NIH's All of Us research program has released the world's largest integrated genomics and health database, covering 747,000 participants with 535,000 whole genome sequences linked to nearly 482,000 electronic health records and over 1.3 billion genetic variants. Notably, more than 86% of participants come from groups historically underrepresented in medical research, addressing a major gap compared to datasets like the UK Biobank. The database has already contributed to 1,400+ peer-reviewed papers and is positioned as foundational raw material for AI-driven drug discovery and diagnostics. However, the program faces a 72% budget cut since 2023 and a key funding stream set to expire, raising serious concerns about its future despite its scientific value.

Schneier on Security

Papa Johns partnered with NBCUniversal, Instacart, and media agency Carat to build a surveillance-based ad targeting system that predicts when consumers are running low on groceries. By analyzing Instacart purchase patterns for staples like eggs, milk, and produce, the system estimates which days specific consumers are likely to have an empty fridge and serves them targeted ads on NBCU streaming. Bruce Schneier draws a parallel to Target's 2012 pregnancy-detection campaign, noting that the strategy for avoiding the 'creepy' label is to deliberately introduce some wrong predictions to obscure the depth of surveillance.
