Why do you need C in the source code ?

[go-nuts] Re: About the Google logo on the new Go website

[Anca Emanuel]

Mozilla had many projects, including languages for the web.
Did they advertise about ? No. They simply take over the world.
Microsoft battle ? Nah, now they are behind.
Google is relatively new in the market. They take an open source browser 
engine, work with Apple and others to make some improvements.
Apple call it Safari, Google call it Chromium.
Some engineers at Google observe that their projects take unusual compile 
time. And that start the discussion of why ?
Or what can you do ?
When you worked on early versions of C and implemented already another in 
other operating system like plan 9, you sure have some ideas to improve 
things.
So they think they need an improved C.
This is how the story of Go begins. It is started by the brilliant Google 
employees.l
Some years later, is open source version 1.0 with compatible guarantee for 
any later version.
So, what do you think about an tiny google logo on the web page presenting 
the language ?
For me, that is normal. They started it.

Re: [go-nuts] Some problem I heard in my class: there are n chess players and they play with all others 1 game and no more than 1 game per day.

[Anca Emanuel]

Here is some play version to test it: https://play.golang.org/p/q-Ikcv3kTW9
Notice the line:
// Change the number of players here !

It works ok for small number of players. (no more than 200)

I am not very good in writing test in golang, but visually, there are 
combinations of n people taken 2 to verify, and that is not very hard.
I was thinking about that and I 
have https://github.com/ancaemanuel/comb/blob/master/comb.go to generate 
them ( an classical algorithm to generate combinations of n taken k in 
lexicographic order ) but I got lazy...

How do you make an planing for that event ?

Here is my 
implementation: 
https://github.com/ancaemanuel/comb/blob/master/chess_tournament.go

This was not an easy problem. After some years of thinking an pencil work I 
have an optimal solution.
