Making social cards got a bit fiddly when I had to calculate how large the font needed to be and how the text should be positioned. You can totally solve this problem with math, but I don't want to.
I don't have an actual solution for this. I'm just saying that the gatekeepers in my universe seem to be in short supply.
Essentially I'm a Dev who enjoys Rel, so DevRel feels like a good pivot for me.
Deprecating a CPAN module may not be as straightforward as one might hope, and it's not something that most of us do regularly. Simply deleting a module does not mean that it disappears. There's always another option: adoption.
On Canada Day (July 1), 2026, Anthropic shipped a surprising "easter egg" to users of Claude Code: `2.1.198` includes an efficiency bypass which allows agents to continue on without being blocked on direction from a human.
Cloning a repo that ships its own .claude directory can hand Claude Code a set of hooks you never agreed to. A look at what "trust this folder" actually signs you up for.
A follow-up to Keep It Local: the patch I opened against App::HTTPThis got merged, Dave Cross came up with a better fix, and he wrote it up himself.
A bit of networking: binding an app to localhost (127.0.0.1) differs from binding to 0.0.0.0, and the distinction is important. Let's look at how to keep clodhopper, air, Python's http.server, and http_this either local or on a Tailscale network.
I vibe-coded a dashboard for hopping Claudes. It allows me to see which of my agents are working, stalled, or waiting on me. Under the hood it captures each agent's hook events into a local SQLite database.
On a public repo, a GitHub issue is untrusted input. If an LLM agent reads it as a set of instructions, you've opened the door to prompt injection — and plain old shell injection too.
As I add races to My Mind is Racing, the trail and ultra races stand out because of how cleverly they're named. Here's a fun sampler.
Rather than nagging your AI agent to follow your repo's conventions, consider enforcing conventions with a git pre-commit hook.
I sandboxed Claude to block all network egress. It reached the network anyway — not by breaking the sandbox, but by routing around it.
The third AI Shoulder Surf — a small, no-recording group on Zoom comparing notes on Tailscale home labs, coding from a phone, and giving agents their own scoped identities.
"Businessmen are only amateurs at failure, just getting used to the notion. Writers are the real professionals."
"Learn your instrument. Practice, practice, practice. Then forget all that and just wail."
Bulk-enable private vulnerability reporting across your GitHub repos with a short shell script.
A roundup of the command-line tools and terminal setups shared at the 2026 edition of our now-annual CLI throwdown at the Perl Toolchain Summit.
The second AI Shoulder Surf — a friendly group on Zoom, no recording, honest notes on the AI tools they're really using and where they sandbox them.
Dependabot's defaults can make it look like an agent of chaos. Cooldowns, dependency groups, and a Claude skill turn down the churn from 11.
