I disagree with error handling proposals that hide the program flow's
branching statements.
In 1976, Thomas McCabe found a correlation between branching statements and
bugs. His cyclomatic complexity uses program flow to measure code
complexity. It is important that branching statements be pla

The operator support is what makes things so complicated. Why not define a
“numeric” type that has methods for all the operators that is used with
generics, similar to Number in Java. Then it is unified. If you are writing

Hello, list.
I had a goal, which was to use surf as a dedicated browser that lives on
the same desktop as my terminal emulator in which I vim. I wanted to
have this dedicated browser as a spot to browse godoc on-demand as a
result of triggering go-doc-browser in vim-go.
I wanted to be sure that s

Hi,
I have a problem when trying to run the test for runtime when CGO is
enabled. The test I want to run is CGO_ENABLED=1 go test
-run=TestCgoSignalDeadlock inside src/runtime of the goroot. This test on
my machine never compile the c files and hence led to link problem while my
other CGO progr

I used 1.12.6 Go library to develop GoLang Application with Beego framework.
When I generate Binary in Linux box and run that binary in same linux box, its
run fine.
Issue is: when I generate Binary in Jenkins Pipeline, and run that binary in
Linux box, it gives error, epollwait on fd 4, and n
I feel like https://go2goplay.golang.org/p/RLn9BXjU1OR is a better

No, that's not possible. A generic function can only work with *either*
built in operators *or* methods. So, you always need to have two functions:

I'd be grateful if people could give me an example to help me understand
the generics draft. Suppose I've got these two functions:
func MemberInt(x int, a []int) bool {
for _, v := range a {
if v == x {

Martin Møller Skarbiniks Pedersen,
Use a RoundUp function for n / d. For example,
// n / d rounded up
func RoundUp(n, d int64) int64 {
if d == 0 {
return 0
}
return (n + (d - 1)) / d
}
