5 Backend Design Patterns for Managing Threads and Sockets

The podcast explores multi-threaded application design within networking, specifically TCP connection management. It questions how backend applications handle client connections and the limits of a single machine. The discussion covers the evolution from single-core processing to multi-core CPUs and the rise of multi-t...

The beauty of the CPU

The CPU operates as a beautiful but highly constrained instrument that cannot execute instructions directly on data residing in main memory. Because memory is physically and logically distant from the processor, data must first be loaded into local 64-bit registers within a specific CPU core before any operation, such ...

The genius of long polling

This episode explores the long polling design pattern in backend engineering. The speaker begins by contrasting short polling's inherent chattiness and resource intensiveness with the more efficient long polling approach. More significantly, the discussion details how long polling minimizes unnecessary requests by on...
