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

The Treehouse Show is our weekly
conversation with the Treehouse community.

This episode we'll be chatting with the
early adopter, Treehouse Android teacher,
0:10
and disc golfer, Ben Deitch.
0:15
[NOISE] Thanks for being on the show Ben.
0:17
Yeah, glad to be here.
0:18
>> I've got a question for you.
0:20
>> Shoot.
>> How did you get started in technology?
0:21
>> And
I'm a little embarrassed to answer this.
0:25
>> Okay.
>> But Flash.
0:27
>> Flash?
0:29
>> And Flash is not a very popular thing.
0:29
>> Right.
0:32
>> But,
>> In my junior year of college
0:33
my professors wanted us to make websites.
0:35
>> Okay.
0:37
>> Because he thought that
everybody was gonna need a website.
0:38
>> He was right.
0:39
>> He sure was.
0:40
>> Yeah.
>> So
0:41
I had to choose between Dreamweaver and
Frontpage.
0:42
>> Okay.
0:45
>> And I chose Dreamweaver.
0:46
>> Okay.
0:47
>> And then in Dream Weaver they
had this little flash thing and
0:48
they're like you can do all these
animations so I made some silly animation
0:50
that I put at the top of the screen,
and that was awesome.
0:53
>> What did it do?
0:55
I don't remember.
0:56
>> Okay.
[LAUGH]
0:57
>> But it got me hooked on this
0:58
just kinda in an activity so
I could hit a button, so
1:00
first it was just an animation-
>> Right.
1:03
>> And then I figured out that
you could hit buttons and
1:05
make it do things-
>> Cool.
1:07
>> And I was hooked.
1:08
>> Right.
>> And I started doing all this Flash
1:10
stuff, and eventually I made
1:12
kind of a Minecraft clone-
>> Really?
1:14
>> In Flash.
1:16
>> Wow.
1:17
And then eventually I hit an op
code limit for the GPU for
1:18
writing shaders in Flash right which you
1:23
know Flash you're like what are you
doing in Flash with GPU stuff.
1:27
So that got me to look into Java and
1:30
then I implemented the MineCraft clone in
the same way in Java, and then C Sharp.
1:33
And then I wanted to do it on android and
then that's how I got to android.
1:38
>> Okay.
>> And
1:42
it eventually became
a live wallpaper instead.
1:42
And so I started android,
I got into android doing GPU stuff.
1:46
Which is like not Even Android
>> Wow
1:50
>> stuff so yeah, kind of a weird path.
1:52
>> Yeah, I don't think that's embarrassing
at all though, I think that's super cool.
1:54
>> Yeah, I agree, but, flash.
1:57
>> Flash, right,
it takes a knock in there.
2:00
So what do you teach here at Treehouse?
2:03
Mostly Android, with a side of Kotlin
2:05
>> Right
>> Which
2:08
is
>> That's cool
2:08
>> Yeah, a really cool way
2:09
to do Android stuff.
2:10
And it's also kind of a way that you
can do front end now with it, and
2:11
it will transpile,
2:14
I think is the right word, to Javascript,
as well as there's callin native.
2:15
Which is interesting and
I don't know much about it, and yeah so
2:19
that's awesome
>> Awesome
2:22
>> And then in addition to that
2:24
I'm working on some SQL content to
2:25
help students get a lot of practice in
kind of a real world SQL environment.
2:27
>> I'm really excited about that too.
2:30
>> That's fun, that's awesome man.
2:31
What is something that the students
might not know about you.
2:33
>> I'm really into aetherium right now.
2:39
>> What's aetherium?
2:42
>> It is.
2:43
>> I guess the easiest way to
explain it would be as kind
2:45
of BitCoin's little brother right now.
2:49
>> [LAUGH]
>> But that's really not doing it justice.
2:51
>> Okay, so explain, let's back up,
BitCoin, I have heard the term.
2:54
I don't exactly understand what that is.
2:57
>> Yeah, so BitCoin
>> What it allows you to do right
3:00
now is you can basically send BitCoins and
3:03
receive BitCoins to people anywhere in
the world, and it's fairly easy to do.
3:05
>> Okay.
3:09
>> And it's being used as a currency, so
you can kinda trade value with somebody
3:10
in, say, China,
just over the Internet really easily.
3:14
And that's nice, but in Ethereum,
this is in BitCoin too, but
3:18
it's a lot harder to do.
3:21
And with Ethereum you have this
concept of smart contracts.
3:22
Okay.
3:25
>> And smart contract,
let me just back up another step.
3:26
Another way that you an think of
the is like a global computer.
3:30
>> Okay.
3:33
>> So whereas BitCoin is global and
everybody.
3:34
So, one thing about
BitCoin is that everybody,
3:37
every node in the network has a copy
of the entire transaction ledger.
3:40
>> Okay.
3:44
>> So, it's
>> Whoever
3:45
has the node knows that Craig
has this many bitcoins.
3:49
>> Okay.
>> They can just figure it out.
3:52
There's a global state
of bitcoin ownership.
3:54
>> Okay.
3:58
>> And with Ethereum,
you can have this global state of, and
3:58
the tokens are called ether,
ether ownership.
4:02
But what they can also do is in that
global state, you can have contracts.
4:06
And what a contract is is
like a little program.
4:09
>> So you can have say, let's say you're
a movie and you set up a contract,
4:12
what the contract does is that any
money that comes in to this contract,
4:16
it's just gonna split that out
to some predefined addresses.
4:20
So, if you wanted people to take
a percentage of gross on the movie,
4:23
you could set up all the addresses
in to this contract for
4:27
all the people and the percentages
that they would get of gross.
4:30
>> And
you deploy that contract to the network.
4:33
>> Okay.
>> And then once it's on the network,
4:36
it can't really be changed or anything.
4:39
It's there for people to audit,
they can look at it.
4:40
And then when the movie gets its money,
you just put all the money into that
4:43
contract, and it would automatically
By rule of code, go to those people.
4:45
>> Wow, that's a big mistake
if you code that wrong.
4:50
[LAUGH]
>> Right, yeah, you gotta get it right,
4:53
it's important.
4:54
>> [LAUGH] And
everybody can see the contracts.
4:55
>> Yeah.
>> So there's no hidden money,
4:58
is that kind of the concept?
4:59
Yeah
>> Okay.
5:02
>> But you can still hide it in the same
way you can hide it on BitCoin,
5:03
you can make a hundred accounts and
start trading all between them.
5:06
with VPNs, you really can get
complicated if you like too.
5:11
>> That's like the off shore
banking of- > Exactly like that.
5:14
>> Cool, cool.
5:17
Wow, and
this is such an early adopter thing.
5:20
It seems like you
are always early adopting.
5:23
I think you're the first
person I know who had VR.
5:25
>> Yeah.
>> Could you tell me about your VR
5:27
experience a bit?
5:30
>> Well, VR is just one of those
things where it was like, it's coming,
5:32
you can see it coming, and you just
knew that it was gonna be really big.
5:36
So I wanted to be there for
it when it landed.
5:40
>> Okay.
5:42
And then it took forever to show
up cause Aqua had shipping delays,
5:43
well you don't know but shipping delays so
it took a while to get out there.
5:46
But, yeah, the logic seemed pretty clear
there that I wanted to be a part of this.
5:52
>> Right.
5:56
>> Especially for all the people that,
>> Who aren't me, but
5:57
are around earlier than me.
5:59
And just seeing all the cool VR stuff,
in movies and everybody's so
6:02
excited about VR all the time.
6:05
And it's here.
6:07
>> Yeah.
>> Like it's freaking here.
6:07
>> Right.
6:09
>> So cool.
>> And you actually watched
6:09
>> Flicks on your device, right?
6:11
Is that right?
>> Yeah!
6:13
>> That's where you watch your movies.
6:14
>> Yeah!
>> With a gigantic screen in
6:15
front of your face.
6:16
>> Right.
>> Yeah, that's awesome.
6:17
And you, there's like, social stuff right?
6:19
>> There is, I haven't used it a lot,
because unfortunately,
6:21
not a lot of people have VR yet.
6:25
>> Okay.
>> It's expensive.
6:26
>> I was thinking maybe we could
make that dream come true,
6:29
because I have
>> A headset here.
6:31
Dude did you bring your headset?
6:33
>> I did.
>> Okay.
6:34
Let's go in together and
6:35
we can see what the social
experience is like and record it.
6:37
>> Yeah.
>> All right.
6:40
Let's do it.
6:41
>> Should I be seeing you?
6:42
I'm in this room.
6:43
>> I'm over at the table.
6:45
I'm playing Simon Says.
6:47
Next, map launcher you're
at the games table?
6:51
>> I'm at the games table I don't
see anybody else on the games table.
6:54
There you are,
it's weird that you're over there.
6:57
>> Is that you?
6:59
You're bald.
7:01
>> So are you well we've gotta set our
avatars or whatever that screen was?
7:02
>> What was that?
7:06
>> [INAUDIBLE] Side.
7:07
>> Okay.
7:09
