  1. Concurrency is when two or more tasks can start, run, and complete in overlapping time periods. It doesn’t necessarily mean they’ll ever both be running at the same instant. Eg. multitasking on a single-core machine.
  2. Parallelism is when two or more tasks are executed simultaneously.
  3. A thread is a sequence of instructions within a process. It can be thought of as a lightweight process. Threads share the same memory space.
  4. A process is an instance of a program running in a computer which can contain one or more threads. A process has its independant memory space.

• The Dark Path

1. It’s not the fact that Swift and Kotlin are statically typed that has me concerned. Rather, it is the depth of that static typing.
2. And what is it that programmers are supposed to do to prevent defects? I’ll give you one guess. Here are some hints. It’s a verb. It starts with a “T”. Yeah. You got it. TEST!
3. But before you run out of fingers and toes, you have created languages that contain dozens of keywords, hundreds of constraints, a tortuous syntax, and a reference manual that reads like a law book. Indeed, to become an expert in these languages, you must become a language lawyer (a term that was invented during the C++ era.)
