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. + -- cgit 1.4.1
