I built Markdown Viewer because every Markdown app I found was either bloated (VS Code, Obsidian) or too bare-bones. Wanted something that loads instantly, renders Obsidian-style features cleanly, and weighs in at a few megabytes.

Built with Tauri 2 (Rust backend + webview frontend): - GitHub Flavored Markdown + Obsidian extensions (wikilinks, callouts, emoji, math, Mermaid diagrams) - Frontmatter rendered as a structured metadata bar above content - HTML sanitization via ammonia for security - No heavy dependencies, no Electron

What makes it interesting isn't so much the features — but how it was built. Every line of Rust, CSS, and JavaScript was written by AI coding agents (pi.dev/Qwen and Claude Code) without a single human writing code. No hand-holding, no "prompt then copy-paste" — just a high-level brief and iterative agent-driven development.

I've been using this project to hone into my pi.dev setup - am getting somewhere with pi.dev/Qwen3.6 with a small set of extensions. Trying to avoid Claude Code/Opus for this project - want to see what I can do with local LLM.

Key stats: - Instant load (no webview overhead, pure rendering) - ~few MB binary - Sanitized HTML via ammonia (XSS-safe) - Open source on GitHub

On April 23, 2026, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) issued an update to V1: Emergency Directive (ED) 25-03: Identify and Mitigate Potential Compromise of Cisco Devices related to Cisco Secure Firewall Adaptive Security Appliance (ASA) and Cisco Secure Firewall Threat Defense (FTD) products.

According to the update, the ArcaneDoor threat actor has developed a previously unknown persistence mechanism that is preserved across upgrading to the fixed releases that were published in September 2025. This persistence mechanism resides in the Cisco Firepower eXtensible Operating System (FXOS) Software base operating system for Cisco Secure Firewall ASA Software and Cisco Secure FTD Software installations on the affected hardware platforms.

Note: According to the intelligence Cisco PSIRT has received to date, the initial compromise, begins with the attacker exploiting the following vulnerabilities before customers upgraded to the fixed releases that were made available in September 2025:

• CVE-2025-20333: Cisco Secure Firewall Adaptive Security Appliance Software and Secure Firewall Threat Defense Software VPN Web Server Remote Code Execution Vulnerability
• CVE-2025-20362: Cisco Secure Firewall Adaptive Security Appliance Software and Secure Firewall Threat Defense Software VPN Web Server Unauthorized Access Vulnerability

For more information about the fixed releases that were made available in September 2025, see Cisco Event Response: Continued Attacks Against Cisco Firewalls.

A bipartisan bill would ask electric vehicle and plug-in hybrid drivers to pay annual fees because they don't pay gas taxes.
