What does ‘–set-upstream’ do?

To avoid confusion,recent versions of git deprecate this somewhat ambiguous –set-upstream optionin favor of a more verbose –set-upstream-to optionwith identical syntax and behavior. sets the default remote branch for the current local branch. Any future git pull command (with the current local branch checked-out),will attempt to bring in commits from the <remote-branch> into the current local branch. One way to avoid having to explicitly type –set-upstream / –set-upstream-to is … Read more

Generate unique random numbers between 1 and 100

For example: To generate 8 unique random numbers and store them to an array, you can simply do this:

Which equals operator (== vs ===) should be used in JavaScript comparisons?

The strict equality operator (===) behaves identically to the abstract equality operator (==) except no type conversion is done, and the types must be the same to be considered equal. Reference: Javascript Tutorial: Comparison Operators The == operator will compare for equality after doing any necessary type conversions. The === operator will not do the conversion, so if two values are not the … Read more

sphinx.ext.autodoc: Keeping names of constants in signature

You probably have to override the signature by hand in the reST file. It’s hard to come up with a better answer. Autodoc imports the modules it documents, so all module-level code (including default function arguments) is executed. See also these similar questions: here and here. Update: I just realized that there is another option. You can override the signature … Read more

Working on code to calculate cosine with factorial sum

One thing I see, is that your for loop within main only runs through 2 real iterations, once for i == 0, and again for i == 1. For the taylor expansion to work fairly effectively, it needs to be run through more sequence terms (more loop iterations). another thing I see, is that your … Read more

Implementing Taylor Series for sine and cosine in C

Anything over 12! is larger than can fit into a 32-bit int, so such values will overflow and therefore won’t return what you expect. Instead of computing the full factorial each time, take a look at each term in the sequence relative to the previous one. For any given term, the next one is -((x*x)/(flag_2*(flag_2-1)) times the previous one. So … Read more

How do you use the ? : (conditional) operator in JavaScript?

This is a one-line shorthand for an if-else statement. It’s called the conditional operator.1 Here is an example of code that could be shortened with the conditional operator: This can be shortened with the ?: like so: Like all expressions, the conditional operator can also be used as a standalone statement with side-effects, though this is unusual outside of … Read more
