  HTTP is not a transport protocol, HTTP is not RPC

The argument is valid when looking at HTTP from the standpoint of an RPC mechanism, which is actually a quite co...

  Do designers need code?

So many problems in software occur because programmers and designers don't communicate well all the time. Why don't more designers learn to code themselves or have engineers build abstractions better suited to them? People's minds work in different ways, they can process thoughts differently, solve problems in completely different but equally valid ways. It's a mistake to assume everyone should possess the same skill set.  Also not everyone should be a full stack engineer although full stac...

  What Happened to Software Engineering?

Over the past few years there has been an evolutionary shift in the world of software development.  Not very long ago, the dominant Software Development Life Cycle (SDLC) methodology was the Waterfall Method with very specific phases that separated the construction phase from phases like design and test. The software development industry, still very new, was striving to find a repeatable, predictable process for developing software.  The best model for this seemed to be the physical sc...

  Difference between localhost and 127.0.0.1

Lots of people would think what the address 127.0.0.1 is when first seeing this address. In fact, 127.0.0.1 is a loopback address which refers to the local machine. It is generally used for local testing. When typing ping 127.0.0.1 on local command console, it will send network packets to local IP/TCP layer to test whether IP/TCP works properly or not.  To those who are used to use localhost, it is actually mapped to 127.0.0.1 by default. There are hosts files in the system which store this...

  About tmpfs

tmpfs is another confusing name in Linux kernel, its implementation is in mm/shmem.c, shmem has no relation to tmpfs at first glance although we know tmpfs is based on memory.
