Go gets compared to Rust because go was originally labeled a "systems" language. But the designers had a different older view of what "systems" meant than what is commonly used to day. People heard systems and thought they meant low level/operating system/embedded systems. That is not what Go is good for because it's garbage collected. They also planned to attract C++ programmers, but they've basically been attractin…

Yeah, additionally it would be unwise to use Go in embedded systems because it is so reliant on heap memory for dynamic allocation. In certain situations where things could fail if an operation takes too long - rocketry and robots - it would be difficult to tell how long something would take in Go with any degree of certainty because allocating and freeing memory on the heap is highly non-deterministic.

I wonder how Go can be better than Swift for iOS development.

It may not always be better since you'll likely never be able to call from Go into Cocoa libs, but if you can write a shared library and use it on the server, iOS and Android, then it's a big win. Linking a Swift app against the shared Go library and calling directly from Swift into Go sounds pretty great to me.

Nice little change in syntax. m := map[Point]string{ Point{29.935523, 52.891566}: "Persepolis", Point{-25.352594, 131.034361}: "Uluru", Point{37.422455, -122.084306}: "Googleplex", } may now be written as: m := map[Point]string{ {29.935523, 52.891566}: "Persepolis", {-25.352594, 131.034361}: "Uluru", {37.422455, -122.084306}: "Googleplex", }

I'm puzzled about the asymmetry of the syntax. What's the reason behind map[Point]string as opposed to something more symmetrical?

Can you elaborate on the different meanings of 'systems programming'? I just thought it meant OS development.

The same was true during the Microsoft Build event, the difference was that a lot of Microsoft employees registered a new (green) HN account. Not that I'm complaining but it looked more like a coordinated effort than Go language which has minimal PR from Google but is used by many devs around the world and is very big in Asia.

There are a lot of MS employees on HN normally, no need for green accounts. Also, where is Go popular in Asia? I haven't heard much about it in China (it isn't a resume point yet).
