Advanced Programming in the Unix Environment
Week 5: The Unix Development Environment
This week, we cover the concept of the Unix userland as an Integrated Development Environment. This introduction outlines the different tools we will cover in subsequent videos, including the editor, the compiler chain, make(1), the debugger, and code revision and management tools. No vibe coding here.

Week 5: The Editor
In this video lecture, we look at the required feature for a full-fledged programmer's editor and illustrate some of the core functionality by example of vim(1). This includes basic motion commands, setting and moving to markers, using folds, and the use of the ':make' and quick fix lists to address compiler errors efficiently.
(Don't worry, we'll talk about ed(1) later.)

Week 5: The Compiler Chain, Part I
In this video lecture, we begin our discussion of compilers as part of the Unix programming environment. We provide a high-level overview of how compilers process input source code and turn it into an executable.

Week 5: The Compiler Chain, Part II
In this video lecture, we look at the preprocessing stage of the compiler and observe how it invokes the cpp(1) command to include header files or replace macro definitions in place.

Week 5: The Compiler Chain, Part III
In this next-to-last part on the compiler chain, we look at the compilation proper and the optimization and assembly of the intermediate code into an object file. (We will revisit some of this when we take a closer look at shared libraries in week 11.)

Week 5: The Compiler Chain, Part IV
In this video lecture, we conclude our discussion of the compiler chain, analyzing the last step in the process: linking the object files into the executable. We identify aspects of the C Runtime libraries as well as the standard C library that we need to include and cover a few of the most important flags to ld(1).

Week 5: make(1)
Moving on from the compiler, we now look at how the make(1) utility can be used to help us selectively build our code project.

Week 5: Debugging your code
Next in our discussion of the Unix _development_ environment, we start a short series on the use of a debugger by example of gdb(1). First, we illustrate just why exactly we might want to use a separate tool instead of sprinkling "printf" statements all over our code...

Week 5: Using gdb(1)
Alright, let's look at gdb(1)! We begin by using it to troubleshoot our failing programs and immediately identify the location of our program where it segfaults. We also see how to inspect variables and call functions from within the debugger.

In this video lecture, we continue to explore the capabilities of the debugger. We show how you can set a breakpoint to pause the program and how to step through the program while watching our code.

Week 5: Using gdb(1), part III
In this video lecture, we'll use our newly learned debugging skills to analyze and fix yet another flawed program. In the process, we learn to debug code from multiple source files and find out how to change the value of variables while the program is running.

In our last segment on gdb(1), we use the debugger to examine memory locations in a running program and illustrate how pointers and arrays work in the C programming language.

Tool Tip: ed(1) is the standard text editor
As part of our discussion of unix development tools, we take a short detour to provide a quick walkthrough of ed(1), the standard text editor. This is not done merely to up your geek creds, but understanding ed(1) will also helps us better understand other tools like vi(1), sed(1), and ultimately even things like diff(1) and patch(1) better.

@carlopiana There's nothing offensive about calling a spade a spade. Talking about an attack on journalists when it was a serious act of vandalism, but limited to newsroom property, is a manipulation of the facts. It's equally manipulative to accuse a woman like Francesca Albanese of supporting this act of vandalism, a woman who is now the target of a very serious and disproportionate personal attack by the United States, which is now exploiting its dominance over international organizations to target her personally, even before her work.

@hongminhee@hollo.social Pro tip: you can always give old keyboards to someone you know and get new ones. (I'm not begging btw)

il furto di identità è un problema complesso, la cui soluzione non è affatto facile, ammesso che esista. Il discorso dovrebbe basarsi su un'analisi del rischio, cioè sulla probabilità di accadimento degli eventi avversi moltiplicata per il danno economico nel caso di accadimento degli eventi avversi. Purtroppo questo calcolo e relative decisioni non sono in mano al cliente della banca...

@feorag should we expect significant amounts of snow tomorrow? a catastrophe or two?
