Building a toast component (11 minute read)
Sonner was a library released in 2023 that quickly became the default toast component for shadcn/ui, despite a crowded market. Its success was due to its well-implemented stacking animations achieved with interruptible CSS transitions, and intuitive functionalities like momentum-based swipe-to-dismiss and expandable toast displays. The developer experience was also unique, with interactive documentation, a simple, hook-free API using the Observer Pattern, and a promise API for managing toast states. |
Representing Hierarchies (3 minute read)
There are two common methods for representing hierarchical data structures, like HTML elements or file systems. The "obvious way" uses an array of pointers to child nodes, which allows for convenient indexed access but introduces dynamic memory allocations and potential cache misses. The "allocation-free way" uses first-child and next-sibling pointers, removing the need for dynamic memory management for child relationships and improving cache efficiency. |

AI Makes Exploration Cheap, Not Decisions Easy (6 minute read)
AI doesn't make decisions for you, but it makes exploring ideas much cheaper. While AI can generate options, prototypes, and directions much faster now, the hard part is still using judgment to pick what actually works well, both engineering-wise and product-wise. |
Vibe Coding Without System Design is a Trap (18 minute read)
AI tools primarily optimize for immediate functionality rather than proper, evolvable system design. This often results in "accidental architecture," which has hardcoded values, little-to-no testing, and a wide range of edge cases, making products fragile and expensive to maintain or change over time. To counteract this, devs must apply systems thinking and product management discipline before using AI by consciously designing for future changes and dependencies. |
Why devs need DevOps (13 minute read)
The software engineering industry is at risk of knowledge deterioration, where the foundational thinking behind successful practices like DevOps is lost. The core of DevOps includes optimizing the entire flow of value, establishing short feedback loops to identify issues early, and ensuring continuous learning across the team. Internalizing these principles grants developers predictive power. |

Mantic (GitHub Repo)
Mantic is a structural code search engine for AI agents. It provides sub-500ms file ranking across massive codebases without relying on embeddings or external dependencies. Mantic infers intent from file structure and metadata, reducing token usage and running entirely locally. |
Pi Coding Agent (GitHub Repo)
The Pi Coding Agent is a terminal-based coding agent for headless coding tasks that runs on macOS, Linux, and Windows and supports multiple model providers with mid-session model switching. It has slash-command workflows, session saving + branching, context compaction, bash/tool execution, and customization via settings. It also has SDK/RPC modes for programmatic use. |

Doom Coding (4 minute read)
This is a guide on how to code on a smartphone from anywhere by remotely accessing a home computer. The method relies on a 24/7 running computer, Tailscale for secure networking, Termius as a mobile terminal, and Claude Code for AI assistance. The setup involves enabling SSH, installing Tailscale and Claude Code on the computer, then installing Tailscale and Termius on the phone to connect via the computer's MagicDNS. |
A field guide to sandboxes for AI (36 minute read)
AI agents often need to execute untrusted code, so they use sandboxes. Effective sandboxing requires consideration of three distinct aspects: the isolation boundary, access policy, and execution lifecycle. There are various types of sandboxes, like containers (sharing the host kernel, insufficient for hostile code), gVisor (userspace kernel interposition), microVMs (guest kernel via hardware virtualization), and runtime sandboxes (no direct syscall access). |
Hacking dlopen to statically link Pipewire (11 minute read)
Tuple is a pair programming app that wanted to create a fully static Linux executable, but had a big challenge with PipeWire, which it uses for screen capture. PipeWire's core functionality relies on `dlopen` for internal plugin systems (modules and Spa plugins), making traditional static linking impossible. It solved this by developing a "fake dynamic linker" using Zig, which reimplements `dlopen`, `dlsym`, and `stat` to statically link PipeWire's plugins into an internal symbol table. |
