Upgrading cmake on Raspbian Jessie

Trying to build and install rtl-sdr from source I got this error on a Raspberry Pi 1 running Jessie:

$ cmake ../

CMake Error at CMakeLists.txt:22 (cmake_minimum_required):
CMake 3.7.2 or higher is required.  You are running version 3.6.2

Doing an ‘apt-get update’ and ‘apt-get upgrade’ is not picking up a more recent version, so following the steps here, I downloaded the required 3.7.2 version from source and followed the steps to build it: http://osdevlab.blogspot.com/2015/12/how-to-install-latest-cmake-for.html

I downloaded a .tar for the 3.7.2 version from:

https://cmake.org/files/v3.7

The build look over 2 hours, but completed successfully, and now I’m able to build rtl-sdr.

The Pragmatic Programmer: 1st edition vs 20th anniversary edition – what are the major changes?

I might come back and do a more thorough look at each of these differences later, but I wanted to get a rough idea of what were the main changes to each of the chapters in the recently released 20th Anniversary Edition of the classic book, The Pragmatic Programmer.

There’s probably plenty more other changes even in the sections that are common between both editions, but this is a high level overview of the major differences in each chapter, summarized as:

  • New sections added
  • Sections with major changes
  • Sections removed
