+We will also look at how tools can improve software phases,
+
+2
+00:00:02,960 --> 00:00:06,660
+the software activities, and can support software development tasks in general.
+
+3
+00:00:06,660 --> 00:00:08,890
+And this is something that I will repeat over and over
+
+4
+00:00:08,890 --> 00:00:12,340
+in the class, tools and automation are fundamental, in software engineering.
+
+5
+00:00:12,340 --> 00:00:15,910
+And they're fundamental for improving productivity, not only efficiency but also
+
+6
+00:00:15,910 --> 00:00:19,820
+effectiveness of our activities in the software development process. So let
+
+7
+00:00:19,820 --> 00:00:22,110
+me go back to one of the diagrams that I showed
+
+8
+00:00:22,110 --> 00:00:25,170
+you before. If you remember we had this qualititive diagram in which
+
+9
+00:00:25,170 --> 00:00:27,170
+we were showing that one of the issues that led to the
+
+10
+00:00:27,170 --> 00:00:30,350
+software crisis was the fact that developers' productivity was not able to
+
+11
+00:00:30,350 --> 00:00:33,580
+keep up with the software size and complexity, with the growth in
+
+12
+00:00:33,580 --> 00:00:36,750
+the importance and the complexity of software. What tools can help us
+
+13
+00:00:36,750 --> 00:00:40,150
+to do is to change this and basically move this curve from
+
+14
+00:00:40,150 --> 00:00:43,950
+this original position up here. So that it gets closer and closer
+
+15
+00:00:43,950 --> 00:00:45,970
+to what we need to develop the software that we need to
+
+16
+00:00:45,970 --> 00:00:50,230
+build. So let me discuss examples on how tools can improve productivity.
+
+17
+00:00:50,230 --> 00:00:52,970
+For example, if we are talking about development, think about
+
+18
+00:00:52,970 --> 00:00:54,890
+what kind of improvement it was to go from punch
+
+19
+00:00:54,890 --> 00:00:58,440
+cards to modern IDEs. If we're talking about languages, think
+
+20
+00:00:58,440 --> 00:01:02,210
+about of how much more productive developers became when going from
+
+21
+00:01:02,210 --> 00:01:05,830
+writing machine code to writing code in high-level languages. And
+
+22
+00:01:05,830 --> 00:01:08,750
+finally, if we talk about debugging, which is a very important
+
+23
+00:01:08,750 --> 00:01:12,140
+and expensive activity, moving from the use of print lines
+
+24
+00:01:12,140 --> 00:01:16,060
+to the use of symbolic debuggers dramatically improve the effectiveness and
+
+25
+00:01:16,060 --> 00:01:18,810
+efficiency of development. And these are just some of the
+
+26
+00:01:18,810 --> 00:01:21,050
+tools that we will discuss in the rest of the class
+
+27
+00:01:21,050 --> 00:01:23,350
+and notice that we will also use the tools in practice.
+
+28
+00:01:23,350 --> 00:01:26,290
+So we will use the tools before projects and also during
+
+29
+00:01:26,290 --> 00:01:30,153
+the lessons and for assignments. In particular, we will use
+
+30
+00:01:30,153 --> 00:01:33,920
+three main kinds of tools. The first type is IDE's. And
+
+31
+00:01:33,920 --> 00:01:37,140
+I'm pretty sure you're familiar with IDE's. These are integrated development
+
+32
+00:01:37,140 --> 00:01:41,250
+environments. So, advanced editors in which you can write, compile, run,
+
+33
+00:01:41,250 --> 00:01:43,950
+and debug and even test your code. We'll also use a
+
+34
+00:01:43,950 --> 00:01:48,190
+version control system, systems that allow you to save, and restore, and
+
+35
+00:01:48,190 --> 00:01:51,750
+check the differences between different versions of the code, in particular
+
+36
+00:01:51,750 --> 00:01:53,950
+we will be working with git. We will also be looking at
+
+37
+00:01:53,950 --> 00:01:57,460
+other kinds of tools like coverage and verification tools. These are
+
+38
+00:01:57,460 --> 00:02:00,310
+tools that can help you during testing and I'm a big fan
+
+39
+00:02:00,310 --> 00:02:02,710
+of these tools, so I'm really going to stress the usefulness
+
+40
+00:02:02,710 --> 00:02:05,530
+of these tools and how you should use them in your development.
