Scanner to read file from the end
A while back, I had this task of reading a file backward, line by line, to find a particular value. There is no solution in std lib. So, I tried to use some existent solution from github, like backscanner. But you know what? After wrestling with some tricky corner cases and realising it didn't quite fit my needs, I rolled up my sleeves and came up with my own solution. And just last week, I decided to built a highly effective reverse scanner - rscanner. I tried to cover all those corner cases, made interface similar to bufio.Scanner and kept it effective. Any thoughts or feedback are welcome!

The worst thing about Jenkins is that it works
At a recent job, we had slightly different containers for local dev; our backend containers (for a Go app) had Air [1] installed for live reloading, plus Delve [2] running inside the container for VS Code's debugger to connect to. We also had a frontend container for local dev, which didn't get deployed as a container, just as static files.

Delve v1.21.2 is out now
https://github.com/go-delve/delve/releases/tag/v1.21.2 Thanks Derek and the rest of the team for helping us to debug in a normal way!
- I do not use a debugger
-
Writing and debugging integration tests of multiple processes with Golang
My employer has a commercial solution for this but Delve does supports `rr` traces natively for this purpose, which gives a complete open-source solution (https://github.com/go-delve/delve/blob/master/Documentation/usage/dlv_replay.md).
- No support for debugging Go on OpenBSD
- Delve v1.20.2 is out now

What a good debugger can do
For time travel debugging in Go:
The Delve debugger for Go supports debugging rr traces: https://github.com/go-delve/delve/blob/master/Documentation/...
Undo (who I work for) maintain a fork that debugs our LiveRecorder recordings: https://docs.undo.io/GoDelve.html
Either rr (https://rr-project.org/) or our UDB debugger (https://undo.io/solutions/products/udb/) can do some time travel debugging of Go programs via GDB's built-in support for Go. I believe its weakness is in support for goroutines, since they don't map well onto its idea of how programs run.

Is there a neovim config with preconfigured debugger?
So in my case I use https://github.com/leoluz/nvim-dap-go (which itself calls out to the CLI tool https://github.com/go-delve/delve).
