Perl match in context

Perl match in context

I would like to find a word in a text file, and save it to a variable
along with some characters. for example in the text file it would be
something like:
Isoelectric Point = 6.2505
I'll be looping through a directory of files, so the value of the
Isoelectric Point will change, and that is why I need the characters after
the match to be saved to a variable.

Rails - good practice to specify the action available for a resource?

Rails - good practice to specify the action available for a resource?

Are there any benefits to specify only the routes available in the
routes.rb like:
resources :users, only: [:new, :create]
Instead of leaving out the actions even if there are no views on action
method in the the controller, like:
resources :users
If it's a good practice, what are the benefits?

Perl simple comparison == vs eq

Perl simple comparison == vs eq

On the accepted answer for perl string compare with "eq" vs "=="
it says that First, eq is for comparing strings; == is for comparing numbers.
"== does a numeric comparison: it converts both arguments to a number and
then compares them." "eq does a string comparison: the two arguments must
match lexically (case-sensitive)"
You can ONLY use eq for comparing strings but
both eq AND == works for comparing numbers
numbers are subset of strings so i just dont understand why you would ever
use ==
Is there a reason why you would want to use == for comparing numeric
values over just using eq for all?
