When dealing with a one-to-many or many-to-many SQL relationship in Golang, what is the best (efficient, recommended, "Go-like") way of mapping the rows to a struct?
I have two implementations of the same behavior that I believe should produce the same results but are instead producing different results. When compiled in Go using cgo, I get a different symbol address resolution than when compiled in C. I would like to understand why.
I am using os.Getenv("APP_PATH") to read from the system environment variables and it works fine when running the build of the application normally. But I need to run this Go program as a service which I have done using systemd in which case it cannot read the environment variables. Is...
I am trying to find even numbers in a list of numbers, here is my attempt:It seems straightforward; however, when I run the program, I got the result
I am trying to run a command with go. The command is in a string.The output is:What I'd like to have is:
An easy way to generate a random float64 in [0,1) is by generating a uniformly random int in [0,2⁵³) and dividing it by 2⁵³. This is essentially what rand.Float64() is doing. However, not all possible float64 values between 0 and 1 can be generated this way: if the value is...
If I have an enum:What is more natural Go way to get string of it?fucntion:or methodThe second one is more idiomatic because it satisfies Stringer interface.
I recently read this article http://codearcana.com/posts/2012/05/06/securing-and-exploiting-go-binaries.html which claims in Go that the heap is executable. This raises a few different questions for me about the interaction between the runtime and the operating system.
I saw golang core and found this:What mean IntegerType and Type? It can be C+?Your function declaration is from the builtin package, builtin.make()
Go and C both involves system call directly (Technically, C will call a stub).Technically, write is both a system call and a C function (at least on many systems). However, the C function is just a stub which invokes the system call. Go does not call this stub, it invokes...
