What is starvation? What is race condition? Behavior of software system where the output is dependent on the sequence or timing of other uncontrollable events. What is happens-before relation? What is thread contention? Contention is simply when two threads try to access either the same resource or related resources in such a way that at least one of the contending threads runs more slowly than it would if the other thread s were not running.

Contention occurs when multiple threads try to acquire a lock at the same time. What is a thread-safe function? Can be safely invoked by multiple threads at the same time. What is 2-phase locking? Growing phase, shrinking phase. Guarantees serializablity for transactions, doesn't prevent deadlock. What is the difference between thread and process? Threads of the same process run in a shared memory space, while processes run in separate memory spaces.

What is false sharing , cache pollution , cache miss , thread affinity , ABA-problem , speculative execution? What is sequential consistency? The result of any execution is the same as if the operations of all the processors were executed in some sequential order, and the operations of each individual processor appear in this sequence in the order specified by its program.

What is a memory barrier? A memory barrier, also known as a membar, memory fence or fence instruction, is a type of barrier instruction that causes a CPU or compiler to enforce an ordering constraint on memory operations issued before and after the barrier instruction.

What is data race? When a program contains two conflicting accesses that are not ordered by a happens-before relationship, it is said to contain a data race.

L iskov substitution principle It should be possible to substitute base class with derived class. I nterface segregation principle Many client-specific interfaces are better than one general-purpose interface. D ependency inversion principle Depend upon Abstractions but not on concretions. This means that each module should be separated from other using an abstract layer which binds them together. Source code dependency points in the opposite direction compared to the flow of control.

The Clean Architecture Clean Code Cheat Sheet One key abstraction Aspect-oriented programming The Twelve-Factor App Domain-driven design Microservices are a style of software architecture that involves delivering systems as a set of very small, granular, independent collaborating services.

What is a obstruction-free - if all other threads are paused, then any given thread will complete its operation in a bounded number of steps lock-free - if multiple threads are operating on a data structure, then after a bounded number of steps one of them will complete its operation wait-free - every thread operating on a data structure will complete its operation in a bounded number of steps, even if other threads are also operating on the data structure algorithm?
