Hello, so5team, you wrote: S>>> a) why people appreciate Go and Pzz>> In my opinion, in that posting from the Ration blog on which just you gave the reference, this subject is well uncovered.

Or it something from area "to accept request, to transform to other representation, to give to other subsystem"? Both that and that. Here, for example, a Web server entirely written on Go. Very convenient in usage. It new enough, therefore to me yet was not possible to find in article Internet "as we replaced the apache on on our site with semibillion users, and learned a zen/wallowed in misfortunes". Or, for example, https://letsencrypt.org/- their economy, as far as I understand, too is written on Go. Google states that in their internal economy there are millions the lines written in this language. I.e., serious projects on it are written.

Well, I now in itself, therefore to make such decision to me it was not difficult. At me difficult enough network project consisting of a small site, a certain server economy and which works on the user computer. I solved, as experiment, to study a modern language. Thus the user economy should work on and right now, a poppy and mobile devices - in plans of a different level of remoteness. The server economy works on . The server economy is supposed , and user should not guzzle all processor or all storage at normal loading, i.e. efficiency matters. I selected between , go, and , on D too looked. was very crude at the moment of a choice, and I do not believe that Mozilla squeezes out from itself language-long-liver. Destiny D very much is not clear. It is language which becomes per customer, and competes to a C ++ and C# on their own field. I think, it does not survive, there is no sense with its learning. Learning , unconditionally, is very useful for a head, but language in which lines are represented by the linked list 32-bit characters not seems to me very practical. At too poor libraries. In general, decided to try Go. It was pleasant to me.
