Reading only is safe, but you will have a data race if two goroutines
access the same variable concurrently and at least one of the accesses is a
write. Here is an article that gives some rules of thumb on how to
efficiently schedule parallel computation on separate CPUs:

That's a tough one. If your interviewer is an excellent engineer without an
ego, you may want to point out that it might be better to keep concurrency
and data structures separated. Perhaps you could even tell the story of the
deprecated Java Vector class.

But of course in this case there is an even better solution. :)

The philosophy of Go (in my interpretation) is that exported and unexported
identifiers are only used to describe the public interface of a package and
to guard against certain programming errors; they are not intended to be a
security measure or hide or protect any information. In fact, it's po
I don't know why it's not part of the standard library, but here is a piece
of code that does the job. (It's written in a slightly roundabout way to
make sure that the constants are untyped.)

Here is a short article about how to do OOP in Go with composition,
structurally typed interfaces and, in some special cases, embedding. I
believe this can often be a better approach than traditional OOP modeling
using inheritance. I'd love to hear you thoughts.
Inheritance and OOP: Go one bett
At KTH in Stockholm we’ve been using Go to teach the basics of concurrent
programming for a few years, and we might go ahead and use Go for Computer
Science 101 as well. Preparing for this, I’ve put together a fairly
extensive set of articles, cheat sheets and how to’s at

I fully understand that this can be implemented in many different ways.
That's not my question. Splitting words about "consists of" and "has a"
doesn't add much to the discussion.

I see the dynamic type, which is part of every interface variable, as more
than an implementation detail. The language spec, which is typically very
careful to avoid talking about implementation issues, explicitly states
that an interface variable has a dynamic type:
Variables of interface type
An interface value in Go consists of two parts: a concrete value and a type
descriptor. What is the preferred terminology when talking about this?
The language specification says "dynamic value" and "dynamic type".
However, this doesn't seem to have caught on. The term "concrete value"
seems t
Oops, I missed that one.

Very nice!
Just one comment: you may want to use sort.Strings instead in the sorting
example.

NaN is not equal to NaN. This means that if you use NaN as a key in a
map[float64]string you will not be able to retrieve it again:

I guess this is the way it should be, but it's still a little bit
disconcerting. What's your thoughts on this?

There is a whole bunch of interesting and efficient (both in practice and

This may not be what you want, but starting from Go 1.9 it's possible to
declare a type alias using the syntax
type MyString = string
As opposed to a type definition, an alias declaration doesn't create a new
distinct type different from the type it's created from. Type aliases are

It's well known that radix sort can be faster than comparison-based methods
for string sorting. With that in mind, I wrote this optimized version of
MSD radix sort:

It's equivalent to sort.Strings in the standard library and on my machine
