[go-nuts] why does reading a file on windows add CRLF to unix line endings... sometimes?

I have a test that is failing on travis on a windows build due to the presence of CRLF in the bytes returned by ioutil.ReadFile. The file itself uses unix line endings, so the CR is inserted by something somewhere along the line. However, this is not always the case. On AppVeyor, I do not see

Actually, that comment points to the implementation of WriteString for the fmt package's internal pp type, which in turn is used by other fmt functions to handle strings efficiently. After scanning that source file some more, and the source file for io.WriteString (

I'm a hobbiest new to Go as well. In the x library (still part of the standard library) written by the Go Authors is argon2. It allows for salting, stretching and hashing passwords. The recent guru commentary I've read is that "new implementations of applications which will use password

You do have the option to nest one module within another module in the same repo, but from what I have seen, that is usually not what one wants to do, and especially not to start. It can be tricky to set up correctly, and usually is more work on an on-going basis. The clearest statement I've
