Clash Verge Rev 2.5.6 on macOS works fine in system-proxy mode, but as soon as TUN (virtual network adapter) mode is on, not even Baidu loads. Debugging through the mihomo core's API turned up two independent root causes stacked together. First, Hysteria2's outbound UDP isn't bound to the physical interface, so the TUN routes pull it back in and it loops. Second, Tailscale MagicDNS (100.100.100.100) has taken over system DNS, so queries go out through Tailscale's utun where Clash's dns-hijack can't see them, and come back poisoned. The fix is two Merge overrides: route-exclude-address to keep node IPs out of the TUN, and sniffer to recover domains from SNI. Every step comes with the commands and real output.
A tweet claiming Claude wrote a macOS driver for a Windows-only HP printer pulled 2.62 million views. Pull the repo and you find 6,497 bytes of shell, 7,638 of Python, 550 of Dockerfile — not one line of C. The actual encoding is done by rastertospl, a binary from HP's official Linux driver, running in a Linux container on the Mac. Hacker News caught this. But debunking isn't the point: the genuinely valuable parts of that four-hour session (reading the printer's own error pages, escaping the CUPS sandbox, writing USB directly) and the fact that the decisive turn came from the human, not from Claude, are a precise measurement of where AI's grunt-work ability currently ends.
