Suppose I have a long-running computation that I wish to be cancelable via
a context. By this I mean something that's just churning away on some
computation, not blocking on a syscall or I/O operation or anything like
that. Should I just poll ctx.Err() periodically in the inner loop of my
computati

As of go1.8, do conversions between strings and byte slices always generate
a copy?
I understand the immutability guarantees in the language spec, but I'm
interested in this from an efficiency standpoint. I can imagine a compiler
that analyzes whether a byte slice created from such a conversion

Does anyone know of a golang package that embeds (go-bindata or similar) a
reasonable standard set of CA roots? Ideally such a package would provide a
ready-to-use http.Client.

I am looking for help understanding the following lines in a Go traceback:

Is it possible to have a struct that implements an interface, but have
pointers to the struct not implement the interface? The reason is that I
want to find all the places in our codebase that attempt to use a pointer
to a certain struct as a certain interface.

I am using cgo to wrap a library that creates an OSX UI, which requires
things to be run on the "main thread". Sometimes my cgo calls end up on the
main thread and sometimes they do not (I check this with [NSThread
isMainThread]). I understand that cgo threads are guaranteed to run on an

appreciated.

I have long list of short strings that I want to compress, but I want to be
able to decompress an arbitrary string in the list at any time without
decompressing the entire list.
I know the list ahead of time and it doesn't matter how much preprocessing
time is involved. It is also fine if there is
Is it intended that gob-encoding a pointer to an integer with value equal
to zero decodes as a nil pointer? I was expecting to get back a non-nil

I understand that gob omits zero values but my understanding was that a

The gob docs state that a gob stream consists of
(byteCount (-type id, encoding of a wireType)* (type id, encoding of a
value))*
I was expecting byteCount to be the number of bytes remaining in the entire
packet, but that does not seem to be the case. For example when encoding a

mypkg I can see that the cgo compiler is being run on go-sqlite3.

Under what conditions does a cgo package get recompiled? I am using
go-sqlite3 and it appears that the C compiler/linker is run every time I
build my project, even though I am not changing any of the C sources. I
would have expected it to be run once and then the results re-used, but
