1

00:00:05,750 --> 00:00:10,395

They come back! Before we can

start with any serious work,

2

00:00:10,395 --> 00:00:12,255

let's do some housekeeping.

3

00:00:12,255 --> 00:00:17,380

As you know, this year is a tad special.

While the broad direction is clear,

4

00:00:17,380 --> 00:00:19,730

there are some organizational

details that

5

00:00:19,730 --> 00:00:22,370

still need to be worked

out as we go along.

6

00:00:22,370 --> 00:00:23,930

The main hub for

7

00:00:23,930 --> 00:00:27,215

all the information is the

KEATS page of this module.

8

00:00:27,215 --> 00:00:29,300

Let me say a few words on how

9

00:00:29,300 --> 00:00:35,269

it is organized. The module is

organized into weekly topics.

10

00:00:35,269 --> 00:00:39,785

So there are entries for weeks

one up till week ten.

11

00:00:39,785 --> 00:00:44,390

Let's also proceed in

approximately weekly steps.

12

00:00:44,390 --> 00:00:46,790

Because if you

already asked me in

13

00:00:46,790 --> 00:00:49,130

week two something

about week ten,

14

00:00:49,130 --> 00:00:51,275

then you might confuse me

15

00:00:51,275 --> 00:00:53,720

and also your fellow students.

16

00:00:53,720 --> 00:00:55,970

All the communication in

17

00:00:55,970 --> 00:00:59,945

this module can be done in

the course discussion area.

18

00:00:59,945 --> 00:01:02,300

You can ask any questions.

19

00:01:02,300 --> 00:01:05,465

For example, I haven't

understood this point,

20

00:01:05,465 --> 00:01:07,910

this video isn't clear,

21

00:01:07,910 --> 00:01:10,160

I cannot run this code,

22

00:01:10,160 --> 00:01:13,910

I have problems with

accessing the coursework.

23

00:01:13,910 --> 00:01:16,295

This can be all discussed here.

24

00:01:16,295 --> 00:01:18,590

If you have any private matter,

25

00:01:18,590 --> 00:01:20,900

like, I can't understand why

26

00:01:20,900 --> 00:01:23,465

did I get such a good

mark, for example?

27

00:01:23,465 --> 00:01:27,245

Or there are some private

reasons why you can't keep up.

28

00:01:27,245 --> 00:01:31,430

Please feel free to use

my private email address.

29

00:01:31,430 --> 00:01:35,630

But for any other matter

related to the module,

30

00:01:35,630 --> 00:01:38,480

try to use the course

discussion area.

31

00:01:38,480 --> 00:01:41,510

And I will try to stay on top

32

00:01:41,510 --> 00:01:45,450

of all the discussions

as much as I can.

33

00:01:45,580 --> 00:01:48,500

Each week is organized into

34

00:01:48,500 --> 00:01:52,550

a mandatory section and

an optional section.

35

00:01:52,550 --> 00:01:55,835

The mandatory section

contains videos,

36

00:01:55,835 --> 00:01:58,190

a handout, and the slides,

37

00:01:58,190 --> 00:02:00,725

which I used to

produce the videos.

38

00:02:00,725 --> 00:02:04,324

I recommend that your

first read the handouts,

39

00:02:04,324 --> 00:02:07,430

then watch the videos and then

40

00:02:07,430 --> 00:02:11,030

read the handout

again for each week.

41

00:02:11,030 --> 00:02:14,795

Apologies, some of these

handouts are quite lengthy.

42

00:02:14,795 --> 00:02:17,615

I think the longest

one is 20 pages.

43

00:02:17,615 --> 00:02:19,235

On the good side,

44

00:02:19,235 --> 00:02:21,650

these handouts are

written in such a way

45

00:02:21,650 --> 00:02:24,935

that you can read them just

before you fall asleep

46

00:02:24,935 --> 00:02:26,720

and you should still be able

47

00:02:26,720 --> 00:02:28,835

to understand what is going on.

48

00:02:28,835 --> 00:02:32,105

Also, they contain lots

of pictures and code.

49

00:02:32,105 --> 00:02:35,330

So 20 pages is

a bit misleading.

50

00:02:35,330 --> 00:02:38,870

You can see the second week

is organized similarly.

51

00:02:38,870 --> 00:02:41,030

You will have some videos.

52

00:02:41,030 --> 00:02:42,260

You will have a handout,

53

00:02:42,260 --> 00:02:43,624

you have the slides,

54

00:02:43,624 --> 00:02:45,770

and some optional resources.

55

00:02:45,770 --> 00:02:51,410

I have also put up a general

section, with general

56

00:02:51,410 --> 00:02:57,965

material, where I put

a PDF about my notation.

57

00:02:57,965 --> 00:03:01,385

This might be very

useful because

58

00:03:01,385 --> 00:03:04,610

remember this topic

is already many,

59

00:03:04,610 --> 00:03:07,445

many decades old,

at least 50 years,

60

00:03:07,445 --> 00:03:09,185

and over the time,

61

00:03:09,185 --> 00:03:11,510

many authors and many lecturers

62

00:03:11,510 --> 00:03:13,745

have introduced

their own notation.

63

00:03:13,745 --> 00:03:16,565

So if you read anything

on the web or in books,

64

00:03:16,565 --> 00:03:19,640

you might be confused about that

65

00:03:19,640 --> 00:03:24,035

they call something, which

I call X, they call Y.

66

00:03:24,035 --> 00:03:26,150

So in this PDF,

67

00:03:26,150 --> 00:03:30,320

I have collected all the

information on what kind of

68

00:03:30,320 --> 00:03:34,940

notation I am using and where

I introduce some shortcuts.

69

00:03:34,940 --> 00:03:38,240

The problem is, you always

want to be precise,

70

00:03:38,240 --> 00:03:40,070

but we also lazy.

71

00:03:40,070 --> 00:03:43,745

We don't want to write

everything into the last detail.

72

00:03:43,745 --> 00:03:47,375

So here I say something

about my notation.

73

00:03:47,375 --> 00:03:50,180

I have also put up

a document about

74

00:03:50,180 --> 00:03:53,510

the Scala I'm going to

use in this module.

75

00:03:53,510 --> 00:03:56,090

This is important

for the coursework.

76

00:03:56,090 --> 00:03:58,175

In the coursework which

will come in a moment,

77

00:03:58,175 --> 00:04:00,440

you can use any

programming language you like

78

00:04:00,440 --> 00:04:03,665

to solve the questions and

implement your code.

79

00:04:03,665 --> 00:04:05,615

But, I'm sorry,

80

00:04:05,615 --> 00:04:09,830

all the code I'm going to

show you will be in Scala.

81

00:04:09,830 --> 00:04:12,155

And the main difference is that

82

00:04:12,155 --> 00:04:15,095

between PEP course from last year

83

00:04:15,095 --> 00:04:17,675

is that I'm going to

use the Ammonite

84

00:04:17,675 --> 00:04:21,170

REPL instead of

the Scala REPL.

85

00:04:21,170 --> 00:04:23,615

They work very similarly.

86

00:04:23,615 --> 00:04:26,070

For example,

87

00:04:28,120 --> 00:04:33,710

I can now evaluate code

and get a feedback of what

88

00:04:33,710 --> 00:04:37,100

it calculates, just like the original one.

89

00:04:37,100 --> 00:04:40,220

The difference is that

Ammonite is

90

00:04:40,220 --> 00:04:42,440

an extension and

provides some features

91

00:04:42,440 --> 00:04:44,975

which will be very useful for us.

92

00:04:44,975 --> 00:04:47,600

And I recorded some

of the features

93

00:04:47,600 --> 00:04:50,970

we are going to use

in this document.

94

00:04:52,330 --> 00:04:55,970

The last point to note

on the KEATS webpage

95

00:04:55,970 --> 00:04:59,405

is that in the optional section,

96

00:04:59,405 --> 00:05:02,270

I will always give

the source code of

97

00:05:02,270 --> 00:05:05,845

the programs I discussed

in the videos and in the handouts.

98

00:05:05,845 --> 00:05:08,420

And I really, really

encourage you

99

00:05:08,420 --> 00:05:11,060

that you play around with this code

100

00:05:11,060 --> 00:05:14,420

to make sure you understand

what was discussed.

101

00:05:14,420 --> 00:05:17,540

At the also have sometimes

some additional pointers

102

00:05:17,540 --> 00:05:19,490

to interesting topics, which

103

00:05:19,490 --> 00:05:22,680

you can read up in your own time.

104

00:05:22,690 --> 00:05:26,240

Exams, I'm sorry,

there will be exams.

105

00:05:26,240 --> 00:05:31,760

There will be a final exam in

January, counting for 30%.

106

00:05:31,760 --> 00:05:34,190

There will be a

midterm shortly after

107

00:05:34,190 --> 00:05:37,565

Reading Week, accounting for 10%.

108

00:05:37,565 --> 00:05:40,625

This will be a normal exams,

109

00:05:40,625 --> 00:05:44,780

just that they will be online

in some form or shape.

110

00:05:44,780 --> 00:05:49,939

There will be also a weekly

engagement component.

111

00:05:49,939 --> 00:05:52,370

So 1% in each week,

112

00:05:52,370 --> 00:05:56,360

where I make sure that

you are engaged with

113

00:05:56,360 --> 00:06:01,625

the material and you will

get 1% each week for that.

114

00:06:01,625 --> 00:06:06,020

How that is going to be

working out in practice,

115
