The main difference between `localStorage` and `sessionStorage`
- The main difference between localStorage and sessionStorage lies in how long the data is stored and where it's accessible.
- localStorage persists even after the browser/tab is closed, while sessionStorage's data is cleared when the tab is closed.
- localStorage is shared across all tabs/windows from the same origin, whereas sessionStorage is specific to the individual tab or window.
- Both have around a 5MB storage capacity and store only strings, requiring JSON serialization for objects.

Behind the Underscores EP11: Callable Objects: __call__
- The __call__ method in Python allows objects to behave like functions when implemented, enabling cleaner, modular backend systems.
- __call__ encapsulates state, enables cleaner dependency injection, and facilitates custom middleware or pipelines in projects.
- However, __call__ should be used judiciously as it can lead to readability concerns, debugging difficulties, and unnecessary abstractions.
- Use __call__ when objects need to maintain useful state, fit into callable APIs, or perform a single primary action, such as request logging middleware or authorization checking in backend systems.

The biggest perturbation of satellite orbits
- The J2 effect is the largest perturbation of a satellite orbit from a simple elliptical orbit, caused by the earth not being a point mass but an oblate spheroid.
- The J2 effect is significant for satellites in low earth orbit (LEO) and medium earth orbit (MEO), affecting the longitude of a satellite's crossing of the equatorial plane.
- J2 coefficients, particularly for Earth, show that the J2 effect is small in magnitude but has a notable impact on satellite orbits, with Mars and Neptune having larger J2 values.
- The J2 effect serves as the first refinement in accounting for factors beyond the assumptions of the two-body problem in satellite orbit calculations.
