Highlights:

This month we take a look inside one of the most deeply complex and unfathomable tools in the programmer’s toolkit: the compiler. We also compare the GCC, Clang, and MSVC compilers, with the emphasis on support for C++ standards. Other highlights include:

• Ubuntu 17.10 – Ubuntu gives up the Unity desktop and returns to Gnome. How’s that working out? (page 30).

• Neural Network – This month’s Programming Snapshot puts Python to work on a classic brain teaser. (page 42).

Check out LinuxVoice for alternative directory navigation commands and system rescue with SystemRescueCD.

Better Health

It is hard to think of writing about anything this month but net neutrality. On November 21, the US Federal Communication Commission (FCC) decided on a 3-2 party-line vote to end the requirement that service providers treat all traffic equally, opening the door to "pay to play" scenarios, where ISPs can shake down Internet companies for access to users.

: How Compilers Work

How compilers work

Compilers translate source code into executable programs and libraries. Inside modern compiler suites, a multistage process analyzes the source code, points out errors, generates intermediate code and tables, rearranges a large amount of data, and adapts the code to the target processor.
