... sudo, your packages are installed to the system (/usr/...). This is a bad idea, but workable if you are the only user of the system. If not, they're installed for your user (/home/yourname/...). However, the recommendation to use virtualenvs rather than installing to the system keeps getting strong...

Is “inline” without “static” or “extern” ever useful in C99?

How do you calculate the average of a set of circular data? [closed]
...turning point (which is where the derivative = 0).
Here we will apply the idea of minimise the squared difference to derive the common arithmetic mean formula: sum(a[i])/n. The curve y = sum((a[i]-x)^2) can be minimised in this way:
y = sum((a[i]-x)^2)
= sum(a[i]^2 - 2*a[i]*x + x^2)
= sum(a[i]^2)...
