Displaying application icons in the Windows system tray significantly enhances the usability of background applications. However, when implementing Windows tray icons in Go, there’s a limitation: unlike macOS, only the ICO format is supported. This article explains this difference and introduces practical solutions for converting PNG images to ICO. Icon Format Differences Between Windows and macOS When using libraries that handle tray icons in Go (e.g., github.com/getlantern/systray), there are crucial differences: ...

Many Go developers have previously doubted the performance benefits of sync.Pool. Skeptical questions like “Is it really that fast?” or “Do I need it for small projects?” have been common. However, benchmarks in real-world scenarios clearly demonstrate that sync.Pool is by no means an overrated tool. Benchmark Setup: Realistic Workloads This analysis was performed under the following conditions: Allocation Method: Slice-based buffers (most common in Go) Batch Size: 1,000 objects allocated and returned per iteration Allocation Size: 32 bytes to 131,072 bytes (7 stages) Concurrency: GOMAXPROCS=1 (single-threaded) vs GOMAXPROCS=8 (8 P parallel processing) Crucially, buffers were stored in reusable slices to reflect the cache efficiency of pools in actual applications. ...
