1
00:00:07,930 --> 00:00:10,130
Congratulations.

2
00:00:10,130 --> 00:00:12,735
You've picked up some valuable debugging skills.

3
00:00:12,735 --> 00:00:16,845
Remember your programs aren't going to work the first time and you shouldn't expect it,

4
00:00:16,845 --> 00:00:19,650
but with the debugging skills you've started to pick up,

5
00:00:19,650 --> 00:00:21,270
that won't be a problem for you.

6
00:00:21,270 --> 00:00:24,840
At this point, you should be able to distinguish between syntax,

7
00:00:24,840 --> 00:00:26,970
runtime, and semantic errors.

8
00:00:26,970 --> 00:00:30,060
You should be well on your way to developing a habit of looking at

9
00:00:30,060 --> 00:00:33,840
the error messages and developing a skill of interpreting them.

10
00:00:33,840 --> 00:00:36,540
Learn to love your error messages.

11
00:00:36,540 --> 00:00:40,260
You should be internalizing a mantra,

12
00:00:40,260 --> 00:00:42,765
get something working and keep it working.

13
00:00:42,765 --> 00:00:46,340
Celebrate the small wins and in order to celebrate the small wins,

14
00:00:46,340 --> 00:00:49,625
you first have to have those small wins, and finally,

15
00:00:49,625 --> 00:00:54,060
you should now be recognizing some common errors and how to fix them.

16
00:00:54,220 --> 00:00:58,770
So, today's joke. A manager,

17
00:00:58,770 --> 00:01:00,595
a mechanical engineer, and a programmer,

18
00:01:00,595 --> 00:01:03,020
they're driving back from a convention going over

19
00:01:03,020 --> 00:01:06,380
some mountain roads and suddenly the brakes fail.

20
00:01:06,380 --> 00:01:09,475
They fly their careening down the mountain.

21
00:01:09,475 --> 00:01:15,740
They're scraping against the guard rails and fortunately they finally stop in a ditch,

22
00:01:15,740 --> 00:01:17,225
to their great relief.

23
00:01:17,225 --> 00:01:20,000
All three of them they get out and they start to assess the damage.

24
00:01:20,000 --> 00:01:22,295
The manager says, "Let's collaborate,

25
00:01:22,295 --> 00:01:24,325
let's share our ideas,

26
00:01:24,325 --> 00:01:26,955
work together on this, and we can solve this issue."

27
00:01:26,955 --> 00:01:29,550
The mechanical engineer says, "Well,

28
00:01:29,550 --> 00:01:31,990
let's disassemble the whole car

29
00:01:31,990 --> 00:01:36,050
and we'll analyze each part for failure and figure out what went wrong."

30
00:01:36,050 --> 00:01:38,450
The programmer says, "Hey,

31
00:01:38,450 --> 00:01:40,550
why don't we just push the car back up

32
00:01:40,550 --> 00:01:45,355
the hill and go back down and see if it does it again."

33
00:01:45,355 --> 00:01:48,245
Now, don't be that kind of programmer.

34
00:01:48,245 --> 00:01:50,300
Be more like the mechanical engineer.

35
00:01:50,300 --> 00:01:53,075
Read the error messages, figure out what's wrong.

36
00:01:53,075 --> 00:01:58,620
Your life as a programmer will be a lot more pleasant. We'll see you next time.
