I prefer to come into work a little earlier before our 9 a.m. start time in order to leave before 5 p.m. My boss has no problem with my hours, though an older female colleague apparently does.

Channels provide a way for goroutines to send and receive values, and they are an essential part of Go's concurrency model. Here's a simple example that demonstrates how to use channels in Go: package main import ( "fmt" ) func main() { // Create a new channel with the `make` function ch := make(chan int) // Start a new ...

  Forgotten TODOs: ideas for contributing to open-source projects

I often talk to students that want to contribute to open-source projects, but just don't have an idea what to work on.

The -RI...
