Open tmux, run claude, and it wants me to log in again. Took a bit of digging to figure out it’s a macOS Security Session thing.https://www.junyi.dev/en/posts/tmux-keychain/https://www.junyi.dev/en/posts/agent-mesh/Wed, 11 Mar 2026 04:29:00 +0800junyi.h@comp.nus.edu.sg (Junyi Hou) AI coding assistants are everywhere now, from chat windows to CLI Agents. After using a bunch of them, my biggest takeaway is: no single Agent is the best at everything. I mainly use Claude Code, Google Gemini CLI, and Moonshot Kimi Code day-to-day. At first I treated them as standalone tools, but soon realized that was a waste — each has distinct strengths, and if you let them collaborate and delegate tasks based on those strengths, the results are much better. I call this approach Agent Mesh. Here are my observations and thoughts.https://www.junyi.dev/en/posts/agent-mesh/https://www.junyi.dev/en/posts/nerdctl-tailscale-sidecar-pitfalls/Fri, 06 Mar 2026 00:00:00 +0800junyi.h@comp.nus.edu.sg (Junyi Hou) In containerized deployments, sometimes you need all outbound traffic from a container to go through a specific network exit. Tailscale’s sidecar pattern makes this possible: a Tailscale container acts as a sidecar, other containers share its network namespace, and traffic flows through a WireGuard tunnel via a remote exit node. This setup is well-documented for Docker Compose, but migrating to nerdctl (containerd) introduced a series of pitfalls. Here’s what I ran into so others can avoid the same traps.https://www.junyi.dev/en/posts/nerdctl-tailscale-sidecar-pitfalls/https://www.junyi.dev/en/posts/into-the-modern/Wed, 07 Jan 2026 15:16:00 +0800junyi.h@comp.nus.edu.sg (Junyi Hou) INTO THE MODERN In early 2026, at the “INTO THE MODERN” Impressionist exhibition in Singapore, I stood before an original Monet for the first time. Layers of pigment were stacked high, brushstrokes clearly visible, as if freezing a moment of shimmering dawn or fading dusk from a century ago. At that moment, my mind drifted back to a quiet Sunday exactly ten years prior (2016). I was sitting in front of a computer, flipping through images on the screen one by one, selecting paintings to present for my art class. The theme was “From Tradition to Modernity.” At that time, the word “Impressionism” was still foreign to me, and I could never have imagined that one day I would come face to face with these masterpieces that had once only existed for me as pixels.https://www.junyi.dev/en/posts/into-the-modern/https://www.junyi.dev/en/posts/intel-nuc/Fri, 05 Sep 2025 13:07:09 +0800junyi.h@comp.nus.edu.sg (Junyi Hou) My long‑serving Raspberry Pi 4B has finally met its “successor” — the compact Intel NUC. From ARM to x86, from a TF card to an SSD, this seemingly simple hardware upgrade has brought a qualitative leap to my tinkering experience.https://www.junyi.dev/en/posts/intel-nuc/https://www.junyi.dev/en/posts/replace-keyboard/Fri, 01 Aug 2025 01:16:29 +0800junyi.h@comp.nus.edu.sg (Junyi Hou) As we all know, once keycaps get greasy and shiny (“oiled”), it’s almost impossible to restore them by simply wiping. I once tried sanding the keycaps, but not only did it make things worse, the plastic debris also fell into the gaps between the keys. (You can see my sanded Shift and Space keys in the photo — they look terrible.) While some say you can go to an Apple Store to get them replaced1, it’s said they only allow a few keycaps to be replaced each time. For someone like me whose entire keyboard is shiny, DIY replacement is clearly the more practical option. I’m writing this blog post because I found it incredibly difficult to locate a complete guide on how to replace MacBook Pro M1 keycaps. Most of the videos online2 only show how to remove regular letter and number keys — they deliberately skip over the longer keys like Space, Caps Lock, ESC, and the arrow keys. These keys have different internal structures and require a different disassembly approach.https://www.junyi.dev/en/posts/replace-keyboard/https://www.junyi.dev/en/posts/boost-converter/Fri, 29 Mar 2024 16:42:00 +0800junyi.h@comp.nus.edu.sg (Junyi Hou) Figure 1 – Ultra Boost Converterhttps://www.junyi.dev/en/posts/boost-converter/https://www.junyi.dev/en/posts/github-actions/Mon, 18 Mar 2024 19:57:21 +0800junyi.h@comp.nus.edu.sg (Junyi Hou) # Background How can you prevent others from seeing certain articles in your blog that is hosted by GitHub Pages?
