#1Cloudflare to Cut About 20% Workforce

Cloudflare is eliminating roughly 1,100 positions — about 20% of its workforce. The move comes less than a year after the company hired over 1,000 interns with messaging about "building the future," and commenters are noting the AI-replaces-headcount narrative quietly driving the cuts. The company insists it's neither performance-based nor cost-cutting, but skeptics see classic tech-cycle contraction dressed up in strategic language.

#2Maybe You Shouldn't Install New Software for a Bit

Xe Iaso warns that recent critical Linux kernel vulnerabilities — Copy Fail, Copy Fail 2, and Dirty Frag — have created a perfect storm for supply chain attacks, particularly via NPM. The recommendation is a temporary moratorium on installing new software for about a week, except for essential kernel patches from your distro. The argument: when the vulnerability landscape is this hot, malicious actors have an unusually ripe window to slip compromised packages into your stack.

#3Canvas Is Down as ShinyHunters Threatens to Leak Schools' Data

The learning management system Canvas, owned by Instructure, suffered a major outage after hacker group ShinyHunters defaced login pages and threatened to leak student and institutional data. Schools relying on Canvas as their single platform for grades, submissions, and attendance were thrown into chaos — especially brutal timing during finals season. The incident exposes just how fragile the edtech SaaS monoculture has become.

#4An Introduction to Meshtastic

Meshtastic is an open-source project that turns inexpensive LoRa radios into long-range, off-grid mesh communication networks — no cell service, no subscriptions, no licenses needed. Devices automatically rebroadcast messages across the mesh, extending range dramatically while offering encrypted messaging and excellent battery life. It's gaining traction for emergency comms, remote areas, and anyone who wants resilient communication infrastructure they actually control.

#5Podman Rootless Containers and the Copy Fail Exploit

This deep-dive explores whether Podman's rootless containers offer better protection against CVE-2026-31431 (Copy Fail), which lets users overwrite files they should only have read-only access to. The real danger in container environments is exploiting shared layers between images — a proof-of-concept showed files could be overwritten across containers targeting those shared layers. Results vary by kernel version and configuration, making this a nuanced and active threat.

#6ClojureScript Gets Async/Await

ClojureScript 1.12.145 introduces native async/await support, a top community request for better JavaScript interop. Developers can now annotate functions with ^:async to have the compiler emit native JavaScript async functions directly, eliminating external dependencies for Promise-based APIs. The feature extends to test functions too, making async testing first-class in ClojureScript.

#7GeoJSON

GeoJSON is a format for encoding geographic data structures using standard JSON. It supports geometry types including Point, LineString, Polygon, and their multi-variants, wrapping them in Feature objects with arbitrary properties. This HN front-page appearance is a reminder that sometimes the community just likes revisiting elegant, foundational specs.

#8Tesla Is Recalling Its Cheaper Cybertruck Because the Wheels Might Fall Off

Tesla is recalling all 173 of its rear-wheel-drive Cybertrucks due to wheel studs that could fail, potentially causing wheels to detach while driving. The remarkably small recall number highlights how briefly the cheaper RWD variant was available. HN commenters are drawing comparisons to Rivian's similar challenges engineering 3-ton EVs and questioning Tesla's engineering rigor.

#9Poland Is Now Among the 20 Largest Economies

Poland has quietly climbed into the G20 tier of economies, driven by a combination of EU membership funds, market integration with European supply chains, a strong STEM-educated workforce, and solid post-communist institutional reforms. Notably, Poland was the largest beneficiary of EU funds from 2014 to 2020. Neighboring countries with comparable per-capita support underperformed, suggesting governance quality was the real differentiator.

#10PC Engine CPU

A detailed technical exploration of the HuC6280 processor inside the PC Engine (TurboGrafx-16), written by an emulator developer. Despite the console's "16-bit" branding, the CPU is fully 8-bit — but runs at a blistering 7.16 MHz, twice the speed of the SNES CPU, compensating with raw clock speed. The piece covers unique block transfer instructions and custom additions that make the hardware a fascinating contrast to its Genesis and SNES contemporaries.
