Rankest beginner here. Trying to learn Go by converting an old Visual
Basic application to Go (yeah, right) on Windows 10 (got all the database
stuff working with both postgre and sqlite!) The application needs to read
an .ini file to get path/filename. It bombs on the first line.

1. How much room do you have on your C:\ drive? (if the drive is mostly

No. It is an IDE. You write your code in the top part of the screen. In
the bottom part (the Powershell), you then invoke the compiler with "go
build yourfilename.go".
Did you get Go installed?

I spent most of November studying password hashing and IMO argon2id should
be used for new projects going forward. Very nice implementation in Go in
the x library. I don't speak Java so can't help you there.

Save it as a string, then access the slice parts of the string:
d := datestringtoparse
YY := d[0:2]
MM := d[2:4]
and so forth.

I'm a hobbiest new to Go as well.
In the x library (still part of the standard library) written by the Go

passwords. The recent guru commentary I've read is that "new

Apologies. I'm quite new to Go and what you are seeking is probably over my
head.
