- in python or R, we need to install packages to add functionality to our programs so that we do not have to program everything by ourselves.
- sometimes as the version of a package evolves, it might change behaviour. As a result of this, the code that we wrote two years ago, might not run out of the box anymore.
- even if we do get our code to run properly, it is truly a mightmare to send our code to others and expect them to run it.
- python environments are a solution intended for the above scenarios, where an environment can be trusted to maintain a specfic version of a packages, even if the packages are upgraded. It also becomes easy to send our code to someone else, where they can install the software mentioned in our project directory called
requirements.txt
. - conda environments offer the same feature as above, but for both python and R.

The gender roles as exist in human societies as of a late is more of a social construct than biological. Sure biology has played it's part, but our positions are more conditioned than being biological(innate). We shall solve half our problems if we deconstruct existing notions of sex and sexuality. http://www.therobinhead.com/gender-roles/
Existing gender roles in our societies are a social construct not biological. Separating notions of sex and sexuality will definitely solve the gender-based problems in our society. This webcomic humorously depicts how an alien would feel uncomfortable with our propensity for discretely categorising people.
