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. - |
