Carlana Johnson earthboundkid

On the canonical repository URL

I changed my GitHub username from @carlmjohnson to @earthboundkid (actually, this was a revert because my username was originally @earthboundkid). Because Go uses URLs for package management, this means that existing packages will continue to use github.com/carlmjohnson/requests (for example) and be automatically redirected to github.com/earthbound/requests. There was a discussion about adding package forwarding to Go, but as of now, this has not been implemented. If package forwarding is added to a future version of Go, the URLs of my repositories may change at that time. I may also choose to change URLs if there is a breaking change to the API of a package. The current plan is to migrate package URLs along with a change to /v2 in order to prevent broken go mod upgrades. Thank you for bearing with this transition.

Go iterator proposal experiment

The second problem in Project Euler is

By considering the terms in the Fibonacci sequence whose values do not exceed four million, find the sum of the even-valued terms.

Nine years ago, I wrote a blog post that showed how to solve this in Python using iterators and in Go using channels. The Go code started simple, but ended up a bit complicated because it also had stop channels to allow early exit. See euler.py for the Python code, and channel.go for the Go code using channels.

Go issue #61405 proposes to add a new function-based iterator protocol to Go. To test it, I rewrote the Go code using push function iterators. See functional.go. The code is notably simpler and shorter than the channel based code.
