How to compare Go slices?

Problem: You have two slices that potentially share the same memory buffer meaning that appending to one can cause changes in another one. So, how to understand if two slices share memory? Let’s imagine we have a functions like: func IsMemoryShared(a, b []int) bool { ... } And we want to preserve following behaviour: a := []{1, 2, 3} b := []{1, 2, 3} IsMemoryShared(a, a) // true IsMemoryShared(a[:2]) // true IsMemoryShared(a, b) // false IsMemoryShared(a[1:0], b[1:0]) // false It is known that slice in Go backed by a struct and contain a pointer to a place in memory where slice data is stored and two integers - length and capacity of the slice.

How to open window in MacOS programmatically using Swift

Once I face a problem - “How can I create a normal window on Mac OS?”. Definitely it is possible to use XCode, generate new project using very modern tools and start writing events handling functions/callbacks/delegates/etc. But what if I want to do everything using code, for example last available version of Swift.

Will see how it goes during the time.

Some technical stuff related to this Blog: main “content generation” software I use for doing this blog posts is Hugo preconfigured with one of the minimalistic templates called hugo-classic. It’s my first test of Hugo and it looks very good, very simple to use and just start writing some texts. At some point of time I will create own personal theme maybe based on something but currently I don’t want to spend time on this.
