A graph is built from a collection of nodes and relationships. Entities such as people, locations, items, or categories of data are represented by nodes; and the association between them reflects a relationship. A versatile structure like a graph enables us to model real-world applications–computer networks, social media recommendation engines, bitcoin blockchains, and more. Basing this very structure as a template, we can bring it to life by performing C.R.U.D operations through a unique management system–a graph database.

Abstraction is a principle that enables engineers to create reusable, multipurpose modules throughout their software systems, and both abstraction and indirection are crucial concepts in scalable, robust system development. However, in software engineering, indirection is ultimately the driver for implementing highly decoupled components that perform separate tasks, bringing with it numerous additional organization and cross-team benefits as well.

The guarded suspension pattern is a concurrent pattern which allows a thread that obtained a lock to suspend its execution and temporarily release the lock, waiting for a condition to be satisfied before proceeding any further within the critical section (re-acquiring the lock.)

Properly implemented, microservices can be highly beneficial for an organization, however, beware of the buzz. Few things in IT are low cost/high value, and this is especially true of a microservices architecture.

As we’ve seen, there is a way to write consecutive numbers without loops and conditions if we can find an equivalent way to express them that is broken into a product with a sum representing the number of cross calls.

One day, what was pretty much a homework question popped up on my Quora feed. The question was “Can one write Java code that prints 1 through 100 without using any loop or conditions?”. Straightforward question with more or less inspired responses, each of them more or less wrong.
