## tidbits

### #go

*   layout packages by what they do, not by their abstract type
*   use channels sparingly: write synchronous methods and allow the caller to make it async
*   `append` modifies the underlying slice, you'll only make this mistake once
*   define interfaces where you use them
*   `make([]int, 5)` has a length and capacity of 5. `([]int, 0,5)` has a length of 0 and capacity of 5.  
    `append()` will only do what you want with the latter
*   don't use `init()`
*   TFBO (test, fix, benchmark, optimise)
*   more CPU != more performance  
    more CPU == more contention

### #git

*   `git reflog`
*   `git commit --fixup=<COMMITISH>`  
    `git rebase origin/main --autosquash`

## resources

*   [`proc.go`](https://cs.opensource.google/go/go/+/refs/tags/go1.23.0:src/runtime/proc.go)
