Hi I'm Craig,
welcome to the Treehouse Show.

2
00:00:02,557 --> 00:00:05,235
The Treehouse Show is a weekly
conversation with the Treehouse community.

3
00:00:05,235 --> 00:00:10,133
[MUSIC]

4
00:00:10,133 --> 00:00:13,108
In this episode we'll be talking
to the Treehouse teacher,

5
00:00:13,108 --> 00:00:17,150
tech degree success manager, and
all around great guy Dave McFarland.

6
00:00:17,150 --> 00:00:18,790
Thanks for being on the show today Dave.

7
00:00:18,790 --> 00:00:21,050
>> It is a pleasure to be here Craig.

8
00:00:21,050 --> 00:00:24,740
>> Can you tell us a little bit
about how you got into technology?

9
00:00:24,740 --> 00:00:25,608
Yes.

10
00:00:25,608 --> 00:00:28,366
So, when I was in college,
I was actually an English major.

11
00:00:28,366 --> 00:00:32,314
And I had a job in the library in
the Multimedia Center, it was called.

12
00:00:32,314 --> 00:00:32,858
>> Okay.

13
00:00:32,858 --> 00:00:36,429
>> Yes, and one of the things that I
did was took care of the computers,

14
00:00:36,429 --> 00:00:38,080
where people learned.

15
00:00:38,080 --> 00:00:40,810
The training,
they did Desktop Publishing and

16
00:00:40,810 --> 00:00:44,050
I actually got into desktop publishing,
it was the first thing.

17
00:00:44,050 --> 00:00:45,470
>> What's Desktop Publishing?

18
00:00:45,470 --> 00:00:46,980
>> Yeah right that's an older thing so,

19
00:00:46,980 --> 00:00:52,070
that was actually the design of things
that are printed not on the internet.

20
00:00:52,070 --> 00:00:55,110
They're actually things
you hold like magazines,

21
00:00:55,110 --> 00:00:59,913
news papers, news letters and
I did that actually after college.

22
00:00:59,913 --> 00:01:04,760
I was at, what they call pre-press person,
so I worked at a print shop and

23
00:01:04,760 --> 00:01:08,230
I used computers to lay out
stuff to get it printed.

24
00:01:09,430 --> 00:01:13,313
From there I became a designer,
a graphic designer and an art director.

25
00:01:13,313 --> 00:01:15,520
>> Okay.
>> I went to a small non-profit and

26
00:01:15,520 --> 00:01:19,320
they needed a website it was in
a very early days of the web 1995.

27
00:01:19,320 --> 00:01:22,670
>> Okay I can imagine what
that website looked like.

28
00:01:22,670 --> 00:01:23,400
>> It was great.

29
00:01:23,400 --> 00:01:26,860
It was a beautiful,
beautiful website, it was amazing.

30
00:01:26,860 --> 00:01:30,650
Tables, all table based,
if you even know what that is.

31
00:01:32,080 --> 00:01:35,830
And from there, I actually moved
th UC Berkeley as the webmaster.

32
00:01:35,830 --> 00:01:41,030
That was my title, and
I managed the university kind of front

33
00:01:41,030 --> 00:01:44,588
portal that some people moved to
the computer science department.

34
00:01:44,588 --> 00:01:50,530
I started left college,
left the university and start

35
00:01:50,530 --> 00:01:55,250
up a web development company with the few
other people and did that for a while.

36
00:01:55,250 --> 00:01:56,550
Got into teaching.

37
00:01:56,550 --> 00:01:59,050
>> Okay.
>> So I was teaching at art schools at

38
00:01:59,050 --> 00:02:04,410
a graduate level and undergraduate level
in colleges, and started writing books.

39
00:02:04,410 --> 00:02:04,911
>> Awesome.

40
00:02:04,911 --> 00:02:07,139
>> And then basically taught and
wrote books and

41
00:02:07,139 --> 00:02:09,844
did sort of freelance web development for
many years.

42
00:02:09,844 --> 00:02:10,880
>> Okay cool.

43
00:02:10,880 --> 00:02:12,070
That's great.

44
00:02:12,070 --> 00:02:13,760
What do you teach at a Treehouse?

45
00:02:13,760 --> 00:02:15,560
Where are the students meet you?

46
00:02:15,560 --> 00:02:16,165
>> Where will they meet me?

47
00:02:16,165 --> 00:02:17,159
>> Yeah.
>> I'm all over the place.

48
00:02:17,159 --> 00:02:17,750
>> Yeah.

49
00:02:17,750 --> 00:02:19,310
>> But mostly in JavaScript.

50
00:02:19,310 --> 00:02:24,030
So I'm the teacher that they start off
with mostly, yeah with JavaScript.

51
00:02:24,030 --> 00:02:27,480
And I introduce the language and
that's kinda what I teach.

52
00:02:27,480 --> 00:02:29,820
>> Okay.
Do you teach anything else on the site?

53
00:02:29,820 --> 00:02:34,557
>> Yeah.
I have a Git workshop that I do.

54
00:02:34,557 --> 00:02:36,070
Git gets the-
>> Yeah.

55
00:02:36,070 --> 00:02:41,400
[LAUGH] Git is a version control system.

56
00:02:41,400 --> 00:02:44,911
>> Okay.
>> And GitHub is a very popular sort of

57
00:02:44,911 --> 00:02:50,750
public repository of different
code basis that people write.

58
00:02:50,750 --> 00:02:54,300
They can share code,
work on projects together like

59
00:02:54,300 --> 00:02:57,740
open source projects around their,
so I've taught that as well.

60
00:02:57,740 --> 00:02:59,047
>> Awesome, great.

61
00:02:59,047 --> 00:03:01,978
So outside of what the students
can learn from you,

62
00:03:01,978 --> 00:03:06,083
is there something else that you could
show or share with the students?

63
00:03:06,083 --> 00:03:07,679
What's something they
wouldn't know about you?

64
00:03:07,679 --> 00:03:13,103
>> Yeah well, not a lot of people know
that I'm really good at magic, well.

65
00:03:13,103 --> 00:03:16,883
I do magic [CROSSTALK] Well there
was nothing there a second ago,

66
00:03:16,883 --> 00:03:18,389
it appeared magically.

67
00:03:18,389 --> 00:03:20,047
>> [LAUGH]
>> But I was wondering,

68
00:03:20,047 --> 00:03:21,730
maybe we could do a little thing.

69
00:03:21,730 --> 00:03:22,240
>> I would love to.

70
00:03:22,240 --> 00:03:26,390
>> Because I've always wanted to
show off in front of an audience.

71
00:03:26,390 --> 00:03:28,050
>> I would love to, let's do this.

72
00:03:28,050 --> 00:03:29,340
>> So I got a deck of cards.

73
00:03:29,340 --> 00:03:31,660
52 cards in a deck, right?

74
00:03:31,660 --> 00:03:34,740
So the odds of any one cards 1 in 52.

75
00:03:34,740 --> 00:03:38,290
But the thing is, when you ask people,
like hey what's your favorite card,

76
00:03:38,290 --> 00:03:38,830
whatever?

77
00:03:39,920 --> 00:03:42,070
Pick a card out of thin
air out of your mind.

78
00:03:42,070 --> 00:03:45,170
It's never random, there's usually one or
two that is most popular.

79
00:03:45,170 --> 00:03:47,290
>> Sure.
>> So what do you think is most popular?

80
00:03:47,290 --> 00:03:50,298
>> If I had to guess it's
the ace of spades, right?

81
00:03:50,298 --> 00:03:51,327
>> Yes.

82
00:03:51,327 --> 00:03:53,670
The ace of spades is the most popular.

83
00:03:53,670 --> 00:03:55,970
So what I want to do is a little
experiment here with you.

84
00:03:55,970 --> 00:03:57,900
Why don't you hold out your hand flat.

85
00:03:57,900 --> 00:04:03,170
And I'll put cards here in your hand,
and we're gonna do something together.

86
00:04:03,170 --> 00:04:05,730
I'd like you to take half of those
cards and put them into my hand here.

87
00:04:05,730 --> 00:04:06,830
>> Half of these cards, there we go.

88
00:04:06,830 --> 00:04:08,630
>> Yeah about half of them, that's good.

89
00:04:08,630 --> 00:04:11,365
And what were you thinking about,
were you thinking about ace of spades?

90
00:04:11,365 --> 00:04:12,356
>> The ace of spades, yes.

91
00:04:12,356 --> 00:04:20,586
>> Okay, so what other cards might me work
with that would help us do some magic?

92
00:04:25,599 --> 00:04:27,091
>> Like the 2?

93
00:04:27,091 --> 00:04:29,281
>> The 2.
>> The 2 of Diamonds.

94
00:04:29,281 --> 00:04:31,802
>> Right, we could do that,
or how about 2 aces?

95
00:04:31,802 --> 00:04:35,810
Why don't we try doing that?

96
00:04:35,810 --> 00:04:38,448
>> Okay [LAUGH] [CROSSTALK]
>> Why don't you just flip through your

97
00:04:38,448 --> 00:04:41,770
cards and find a card, something that
you feel, a feeling that you have.

98
00:04:41,770 --> 00:04:44,120
And I'm gonna find it,
this one feels really good to me.

99
00:04:44,120 --> 00:04:46,140
It's all about intuition.

100
00:04:46,140 --> 00:04:47,730
>> So I got to use my intuition?

101
00:04:47,730 --> 00:04:48,770
>> Yeah.
[CROSSTALK]

102
00:04:48,770 --> 00:04:50,600
>> Just sort of, okay.

103
00:04:50,600 --> 00:04:51,520
I'll take that.

104
00:04:51,520 --> 00:04:52,310
You take this one.

105
00:04:52,310 --> 00:04:53,750
>> Okay?
>> All right, so let's exchange.

106
00:04:53,750 --> 00:04:54,440
Put them on top.

107
00:04:54,440 --> 00:04:54,957
>> Put them on top?

108
00:04:54,957 --> 00:04:56,010
Okay.
>> Yeah.

109
00:04:56,010 --> 00:04:58,410
And what did you say
the most popular card was?

110
00:04:58,410 --> 00:04:59,253
>> Ace of spades.

111
00:04:59,253 --> 00:05:02,044
>> Let's see what I gave you.

112
00:05:02,044 --> 00:05:04,316
>> How did you-
>> Yeah, the ace of spades.

113
00:05:04,316 --> 00:05:05,290
Let's see what you gave me.

114
00:05:06,610 --> 00:05:12,181
Wow, we got 2 aces out of 52
cards on our very first try.

115
00:05:12,181 --> 00:05:14,140
>> How did you do that?
>> What do you say, lets do it again.

116
00:05:14,140 --> 00:05:14,895
>> Okay.
>> Lets do it again.

117
00:05:14,895 --> 00:05:17,280
You've got 2 aces,
do you think you can get 4 aces?

118
00:05:17,280 --> 00:05:19,110
>> There's no way that, [LAUGH].

119
00:05:19,110 --> 00:05:20,430
>> There is no way we can get four aces?

120
00:05:20,430 --> 00:05:21,150
>> No.
>> Are you sure?

121
00:05:21,150 --> 00:05:22,120
>> Yeah.
>> Okay.

122
00:05:22,120 --> 00:05:24,780
Let's see, I think there is
a way that we can get four aces.

123
00:05:24,780 --> 00:05:28,290
I think it's by concentrating,
that's how we're gonna get our four aces.

124
00:05:28,290 --> 00:05:29,860
So let's do the same thing, but

125
00:05:29,860 --> 00:05:32,970
concentrate harder this time,
cuz it's gonna be twice as hard.

126
00:05:32,970 --> 00:05:33,800
>> All right.

127
00:05:33,800 --> 00:05:35,674
>> I got a card for you,
you got a card from me?

128
00:05:35,674 --> 00:05:36,815
>> I'm feeling this one right here.

129
00:05:36,815 --> 00:05:38,562
>> Okay, great.

130
00:05:38,562 --> 00:05:39,767
I'm gonna take that.

131
00:05:39,767 --> 00:05:40,687
Why don't you take that one?

132
00:05:40,687 --> 00:05:41,721
>> Okay.

133
00:05:41,721 --> 00:05:42,390
I put it on top again?

134
00:05:42,390 --> 00:05:43,207
>> Yeah put it on top.

135
00:05:43,207 --> 00:05:46,060
And then, what do you think?

136
00:05:46,060 --> 00:05:46,806
One out of 52.

137
00:05:46,806 --> 00:05:47,520
One out of 52.

138
00:05:47,520 --> 00:05:49,124
One out of 52.

139
00:05:49,124 --> 00:05:49,856
Let's see.

140
00:05:52,973 --> 00:05:55,230
>> Dude, how did you do that?

141
00:05:55,230 --> 00:05:59,074
>> What's more amazing about this,
is not only did we get the four aces, but

142
00:05:59,074 --> 00:06:01,439
we got the only four
cards in the entire deck.

143
00:06:03,863 --> 00:06:06,420
All the other cards are completely blank.

144
00:06:06,420 --> 00:06:07,484
>> How did you do that?

145
00:06:09,636 --> 00:06:10,588
Where did you?

146
00:06:13,702 --> 00:06:15,830
