On a recent trip I kept getting connection failures that needed retrying — pages half-loading, API calls timing out, the usual DNS-smells-wrong experience. It was intermittent enough to be annoying but consistent enough that I knew something was actually broken. I narrowed it down to DNS pretty quickly. My GL.iNet MT-3000 travel router was dropping queries or returning nothing for some domains. The culprit turned out to be obvious in retrospect: before leaving I had shut down my Pi-hole servers at home. Those Pi-holes live on my Tailscale network, and my travel router connects back to that network. Somewhere, something was still trying to use them for DNS.

A coworker dropped /copy in our work Slack yesterday and I had to try it immediately. It’s a Claude Code slash command that copies Claude’s last response straight to your clipboard as markdown. Before finding this, my workflow for grabbing a generated code snippet or shell command was embarrassingly manual — select text in the terminal, hope I got the boundaries right, paste it somewhere. Now I just type: /copy And the whole response lands in my clipboard, formatting intact — including code blocks. This is especially useful when Claude generates something multi-part, like a function plus its tests or a sequence of shell commands, where careful selection across scroll boundaries used to be the only option.
