 -   ### Multithreading
 
-<details>
+    Computers today have processors with several physical and virtual cores, and if we take into account server machines, their number can reach up to hundreds. All of these available resources would be good to use to the fullest, for maximum application performance. That is why modern server development cannot do without implementing [multithreading](<https://en.wikipedia.org/wiki/Multithreading_(computer_architecture)>) and [paralleling](https://en.wikipedia.org/wiki/Parallel_computing).

+    -   Creating processes
+    -   Creating threads
+    -   [Corutines](https://en.wikipedia.org/wiki/Coroutine)
+        > Lightweight code execution threads organized on top of operating system threads. They can exist as separate libraries or be already built into the kernel.
+    -   [Linearizability](https://en.wikipedia.org/wiki/Linearizability)
+        > Operations that are performed completely, or not performed at all.
+    -   Lockouts
+        > Using [semaphores](<https://en.wikipedia.org/wiki/Semaphore_(programming)>) and [mutexes](<https://en.wikipedia.org/wiki/Lock_(computer_science)>) to synchronize data.

 -   ### Code quality
 
+    During these long years that programming has existed, a huge amount of code, programs and entire systems have been written. And as a consequence, there have been all sorts of problems in the development of all this. First of all they were related to scaling, support, and the entry threshold for new developers. Clever people, of course, did not sit still and started to solve these problems, thus creating so-called patterns/principles/approaches for writing high-quality code.
+
+    By learning programming best practices, you will not only make things better for yourself, but also for others, because other developers will be working with your code.
