I remember impulsively buying a tent last fall. Aside from setting it up once to check it out, it’s been sitting untouched ever since. The weather turned cold, and I never found the right opportunity to use it. The following weekends were busy with wedding photoshoots (I even ran a red light and lost six points on my license, so I haven’t driven since 😓), then there was a trip abroad, leave adjustments, the New Year, more leave adjustments, my sister starting school, my mom returning home, and days of continuous rain in between.

1. Background Recently, during a joint debugging session, I encountered a situation where a gRPC Server returned nil for a specific interface. Since the Server was functioning normally and the interface was implemented, there were no errors during the call. However, the program suddenly terminated without any log output. The issue was easily reproducible by simulating the return of nil data. In Debug mode, I could see the panic and the call stack information.

Unnecessary Locales: Remove unused language packs in the locales directory.
1// Set language pack before whenReady 2app.commandLine.appendSwitch('lang', 'en-US'); 3await app.whenReady() Dependencies: Ensure that development dependencies are not listed as production dependencies.
File Locking: If Electron-builder prompts that app.asar is occupied, close VS Code.

In Go, strings are immutable, meaning once created, their content cannot be modified. Therefore, each time you concatenate strings, a new string object is generated, which can have performance implications.
Common String Concatenation Methods Using the + Operator 1s1 := "Hello, " 2s2 := "world!" 3result := s1 + s2 Performance Analysis: Each use of the + operator creates a new string, allocating new space equal to the sum of the spaces occupied by the strings to be concatenated.
