How do I import a specific version of a package using go get?
...s, without actually creating repos. E.g. gopkg.in/yaml.v1 vs gopkg.in/yaml.v2, even though they both live at https://github.com/go-yaml/yaml
gopkg.in/yaml.v1 redirects to https://github.com/go-yaml/yaml/tree/v1
gopkg.in/yaml.v2 redirects to https://github.com/go-yaml/yaml/tree/v2

How to convert C# nullable int to int
...r are all correct; I just wanted to add one more that's slightly cleaner:
v2 = v1 ?? default(int);
Any Nullable<T> is implicitly convertible to its T, PROVIDED that the entire expression being evaluated can never result in a null assignment to a ValueType. So, the null-coalescing operator ?...

Finding quaternion representing the rotation from one vector to another
...
Quaternion q;
vector a = crossproduct(v1, v2);
q.xyz = a;
q.w = sqrt((v1.Length ^ 2) * (v2.Length ^ 2)) + dotproduct(v1, v2);
Don't forget to normalize q.
Richard is right about there not being a unique rotation, but the above should give the "shortest arc," which...
For each row return the column name of the largest value
...make examples using sample reproducible):

[1] "V3" "V1" "V2"
A faster solution than using apply might be max.col:

#[1] "V3" "V1" "V2"
