WEBVTT

00:00:16.509 --> 00:00:18.659
Thank you for coming

00:00:18.659 --> 00:00:23.269
and Ruby Conf is always great

00:00:23.269 --> 00:00:30.269
and a keynote make me depressed (laughs)

00:00:32.238 --> 00:00:33.659
You know I'm a programmer

00:00:33.659 --> 00:00:35.260
I'm a language designer

00:00:35.260 --> 00:00:42.260
so you know, my main tasks should be is designing
language

00:00:42.920 --> 00:00:43.739
a great language

00:00:43.739 --> 00:00:48.369
I admit that I did great things

00:00:48.369 --> 00:00:49.149
you know

00:00:49.149 --> 00:00:51.829
that influenced

00:00:51.829 --> 00:00:54.819
so many people all around the world

00:00:54.819 --> 00:00:55.889
including you guys

00:00:55.889 --> 00:00:57.899
so I'm pretty happy with it

00:00:57.899 --> 00:00:59.679
but still

00:00:59.679 --> 00:01:01.899
you know

00:01:01.899 --> 00:01:04.250
I'm not really a great presenter

00:01:04.250 --> 00:01:10.159
nor

00:01:10.159 --> 00:01:11.170
I'm very

00:01:11.170 --> 00:01:18.170
I'm not really good at english

00:01:19.380 --> 00:01:21.069
that always makes me nervous

00:01:21.069 --> 00:01:26.789
anyway, today I'm going to talk about the
fantasy land

00:01:26.789 --> 00:01:29.759
ok

00:01:29.759 --> 00:01:30.039
this way

00:01:30.039 --> 00:01:33.539
fantasy land

00:01:33.539 --> 00:01:37.970
that is a place being away from reality

00:01:37.970 --> 00:01:43.099
the where the unicorn lives

00:01:43.099 --> 00:01:44.649
in Japanese it is called

00:01:44.649 --> 00:01:46.229
genjitsu-tohi

00:01:46.229 --> 00:01:49.069
which is escaping from reality

00:01:49.069 --> 00:01:50.920
my dictionary says that is escapism

00:01:50.920 --> 00:01:53.899
is that correct word or something

00:01:53.899 --> 00:01:55.280
so for example

00:01:55.280 --> 00:02:00.800
so the starting cleanup right before the deadline

00:02:00.800 --> 00:02:05.420
is kinda like escapism

00:02:05.420 --> 00:02:08.030
starting debuging mruby right before the keynote

00:02:08.030 --> 00:02:10.818
is escapism

00:02:10.818 --> 00:02:12.129
that is what I did

00:02:12.129 --> 00:02:14.980
so today

00:02:14.980 --> 00:02:16.620
I'm going to talk about

00:02:16.620 --> 00:02:19.110
oh excuse me

00:02:19.110 --> 00:02:21.610
two fantasy lands

00:02:21.610 --> 00:02:26.249
the first one is kinda like a distopia

00:02:26.249 --> 00:02:29.590
in 1990

00:02:29.590 --> 00:02:31.590
I graduated from university

00:02:31.590 --> 00:02:36.459
I feel old

00:02:36.459 --> 00:02:39.989
I was hired by a software development company

00:02:39.989 --> 00:02:43.230
which does, which did some kind of enterprise
software

00:02:43.230 --> 00:02:48.029
in that, that age

00:02:48.029 --> 00:02:52.799
the software development is totally different
from now

00:02:52.799 --> 00:02:58.819
so we had some kind of three year project
or something

00:02:58.819 --> 00:03:04.219
from the huge company or huge government department

00:03:04.219 --> 00:03:09.189
we had some kind of analysis for months or
even years

00:03:09.189 --> 00:03:13.189
then we wrote some kind of very detailed documentation

00:03:13.189 --> 00:03:14.769
this abstract documentation

00:03:14.769 --> 00:03:16.480
the detailed documentation

00:03:16.480 --> 00:03:19.459
then we code

00:03:19.459 --> 00:03:26.260
which is the translation from natural language
to computer language

00:03:26.260 --> 00:03:30.730
so the process was driven by waterfall process

00:03:30.730 --> 00:03:36.299
so the company's decision was very, very,
very conservative

00:03:36.299 --> 00:03:42.590
so at that time I felt something was wrong

00:03:42.590 --> 00:03:43.779
but I couldn't explain why

00:03:43.779 --> 00:03:47.419
just because it was so natural

00:03:47.419 --> 00:03:50.930
everyone was doing it that way in software
development

00:03:50.930 --> 00:03:52.790
back then

00:03:52.790 --> 00:03:56.389
so I couldn't explain why

00:03:56.389 --> 00:03:57.629
everyone was doing that

00:03:57.629 --> 00:04:01.829
it is quit difficult to tell what is wrong

00:04:01.829 --> 00:04:04.269
when everyone is doing bad things

00:04:04.269 --> 00:04:05.379
right

00:04:05.379 --> 00:04:10.999
so yea I couldn't imagine what was right and
what was wrong

00:04:10.999 --> 00:04:14.219
so after more than 20 years of experience

00:04:14.219 --> 00:04:15.999
I was a pretty experienced programmer

00:04:15.999 --> 00:04:16.418
ah maybe

00:04:16.418 --> 00:04:23.419
now I understand, I now understand what was
wrong

00:04:23.710 --> 00:04:26.660
we were wrong in software development

00:04:26.660 --> 00:04:31.900
that depends on some false assumptions

00:04:31.900 --> 00:04:37.290
we were depending on such false assumptions

00:04:37.290 --> 00:04:39.010
assumption number one

00:04:39.010 --> 00:04:42.440
we know what we make

00:04:42.440 --> 00:04:49.210
back then we believed we are knowing what
we are going to make

00:04:49.210 --> 00:04:54.990
in reality we don't know what software is

00:04:54.990 --> 00:04:59.870
so software does not have any physical entity

00:04:59.870 --> 00:05:03.620
so it is not limited by physical law

00:05:03.620 --> 00:05:08.620
so it can be very, very easily complex

00:05:08.620 --> 00:05:15.620
so, for example, if I were a building architect

00:05:17.490 --> 00:05:21.920
so I design a building like this hotel

00:05:21.920 --> 00:05:25.560
so we need to think about, for example

00:05:25.560 --> 00:05:31.250
about weather, or the strengths of the concrete,

00:05:31.250 --> 00:05:37.560
or iron, or something, the building materials

00:05:37.560 --> 00:05:42.460
then the strength of the building itself can
be

00:05:42.460 --> 00:05:47.640
calculated by physically, easily simulated

00:05:47.640 --> 00:05:50.930
but you know

00:05:50.930 --> 00:05:55.670
when we starting developing software it is
easy, like

00:05:55.670 --> 00:05:57.140
"hello world"

00:05:57.140 --> 00:05:57.940
that's quite easy

00:05:57.940 --> 00:05:59.720
there is no room for bug

00:05:59.720 --> 00:06:03.110
but the software is getting bigger and bigger

00:06:03.110 --> 00:06:09.370
so it's quite difficult to understand say
10,000 lines of code

00:06:09.370 --> 00:06:14.030
but now days software is so huge

00:06:14.030 --> 00:06:21.030
like if I had a Prius here, it is an automobile,

00:06:24.490 --> 00:06:30.080
it has tons of lines of code, maybe hundreds
of lines of code, tons of hundreds

00:06:30.080 --> 00:06:32.560
maybe millions of code

00:06:32.560 --> 00:06:39.560
so it's like, as a software developer, you
can imagine how difficult to ensure no bugs

00:06:41.630 --> 00:06:44.800
in the millions of lines of code

00:06:44.800 --> 00:06:45.580
yeah

00:06:45.580 --> 00:06:46.970
I'm sure I cannot do that

00:06:46.970 --> 00:06:53.970
so, the software can be a most complex creation,
maybe

00:06:54.860 --> 00:06:59.220
and no document but code can explain the details

00:06:59.220 --> 00:07:06.220
so the, we believe we knew what we were going
to make

00:07:06.300 --> 00:07:09.610
but in reality, we didn't

00:07:09.610 --> 00:07:12.020
false assumption number two, which is

00:07:12.020 --> 00:07:16.840
we know what we want

00:07:16.840 --> 00:07:19.580
in reality, it's quite difficult to imagine

00:07:19.580 --> 00:07:26.580
you know, in a waterfall age I write a code
(?? 00:07:27.16) with sophistication

00:07:27.360 --> 00:07:31.770
and I give that sophistication to our client

00:07:31.770 --> 00:07:37.240
then clients said, OK, then we started development

00:07:37.240 --> 00:07:41.460
a few weeks, few months, few years later

00:07:41.460 --> 00:07:43.890
the software was finished

00:07:43.890 --> 00:07:44.850
then I wrote

00:07:44.850 --> 00:07:49.330
if we wrote it to the client, then

00:07:49.330 --> 00:07:53.230
can you imagine what the client said?

00:07:53.230 --> 00:07:54.760
it's not what I wanted

00:07:54.760 --> 00:08:00.520
but, they said yes, this is OK

00:08:00.520 --> 00:08:06.750
but, afterwards, they said, this is not what
I wanted

00:08:06.750 --> 00:08:11.310
even, I admit, I said OK

00:08:11.310 --> 00:08:18.310
but, you know, we couldn't imagine what the
software appears in reality

00:08:19.480 --> 00:08:26.480
so, like a stupid boss says ?? (00:08:23.56)
to the client

00:08:28.530 --> 00:08:31.450
yeah, I complained a lot

00:08:31.450 --> 00:08:34.130
I happened to complain so often, back then

00:08:34.130 --> 00:08:41.130
but one day, I asked my colleague to create
some kind of software

00:08:43.078 --> 00:08:46.430
at that time I was so busy, so I

00:08:46.430 --> 00:08:49.050
I explained what I want to my colleague

00:08:49.050 --> 00:08:52.240
then he created the software, then back to
me

00:08:52.240 --> 00:08:57.470
and I said, this is not what I wanted! (laughs)

00:08:57.470 --> 00:09:01.070
stupid me

00:09:01.070 --> 00:09:06.910
I said I don't know why we should make too
maximize business value

00:09:06.910 --> 00:09:13.910
we couldn't, no, we couldn't understand what
is gonna bring you success

00:09:15.630 --> 00:09:20.990
so we are stupid, too

00:09:20.990 --> 00:09:23.580
so, false assumption number three

00:09:23.580 --> 00:09:24.480
which is

00:09:24.480 --> 00:09:27.560
the situation will not be changed

00:09:27.560 --> 00:09:33.860
in reality, we don't know the future

00:09:33.860 --> 00:09:36.190
we're not prophets

00:09:36.190 --> 00:09:38.190
we have wrong forecasts

00:09:38.190 --> 00:09:45.190
so yeah, in this technology field, we have
a lot of

00:09:46.820 --> 00:09:50.250
we're gonna have this technology, we're gonna
have this, too

00:09:50.250 --> 00:09:53.210
we're gonna conquer the world, so

00:09:53.210 --> 00:09:57.090
most forecasts will be wrong

00:09:57.090 --> 00:09:58.920
so let's face it

00:09:58.920 --> 00:09:59.760
we don't know anything

00:09:59.760 --> 00:10:03.980
20 years ago

00:10:03.980 --> 00:10:07.670
we should have admitted our ignorance, but
we couldn't

00:10:07.670 --> 00:10:11.390
so instead, we ignored our ignorance

00:10:11.390 --> 00:10:18.370
so, when we know little, we have very few
choices, so

00:10:18.370 --> 00:10:23.020
choice number one is a conservative strategy

00:10:23.020 --> 00:10:23.990
learn from the past

00:10:23.990 --> 00:10:29.850
so, this is very good strategy

00:10:29.850 --> 00:10:32.980
and the politicians often take

00:10:32.980 --> 00:10:34.000
conservative

00:10:34.000 --> 00:10:40.810
but it is pretty good unless factors don't
change

00:10:40.810 --> 00:10:44.320
unfortunately not in the IT industry, so

00:10:44.320 --> 00:10:50.300
we change a lot, the situation will change
drastically, day by day

00:10:50.300 --> 00:10:57.300
so, in our industry it's kind of like the
quote from Red Queen in Alice in Wonderland

00:11:02.029 --> 00:11:09.029
"Now, here, you see, it takes all the running
you can do, to keep in the same place.

00:11:09.560 --> 00:11:16.560
If you want to get somewhere else, you must
run at least twice as fast as that!"

00:11:16.890 --> 00:11:21.550
It's our situation, here

00:11:21.550 --> 00:11:25.880
probably, yeah

00:11:25.880 --> 00:11:26.779
it's our situation

00:11:26.779 --> 00:11:32.480
we have to run as fast as we can to be in
the same place

00:11:32.480 --> 00:11:36.190
so, strategy number two is

00:11:36.190 --> 00:11:37.089
ostrich algorithm

00:11:37.089 --> 00:11:43.360
in the ostrich algorithm

00:11:43.360 --> 00:11:49.330
so when the sandstorm comes, ostrich dig in
their head into sand

00:11:49.330 --> 00:11:53.660
and wait until the sandstorm ends

00:11:53.660 --> 00:11:58.040
so the, the ostrich strategy is ignore everything,
and wait

00:11:58.040 --> 00:12:05.040
it is a good strategy

00:12:08.020 --> 00:12:11.440
only when situations will recover

00:12:11.440 --> 00:12:13.760
so sandstorms will end

00:12:13.760 --> 00:12:20.760
so, we will have the clear skies and we

00:12:21.120 --> 00:12:26.170
we can enjoy our climate again

00:12:26.170 --> 00:12:31.020
but, you know, in our industry

00:12:31.020 --> 00:12:32.230
that's not going to happen

00:12:32.230 --> 00:12:36.850
where the situation will change and change
and change and not recover

00:12:36.850 --> 00:12:42.480
so we, we cannot go back to the main frames

00:12:42.480 --> 00:12:47.790
we can go back to the, you know, eighty, fifty
years or something

00:12:47.790 --> 00:12:52.080
so we must keep forward, keep going forward

00:12:52.080 --> 00:12:59.080
so the ostrich algorithm is very good strategy
in the past

00:12:59.490 --> 00:13:01.440
when the situation will recover

00:13:01.440 --> 00:13:06.310
so the, this strategy, this algorithm, is
written in our instincts

00:13:06.310 --> 00:13:10.690
so we are so easy to choose that strategy

00:13:10.690 --> 00:13:17.690
but, otherwise, when the situation will not
recover

00:13:19.660 --> 00:13:21.600
it's kind of like the living in the fantasy
land

00:13:21.600 --> 00:13:28.560
so, going forward with false assumptions is
kind of like living in the fantasy land

00:13:28.560 --> 00:13:35.560
so, ignoring reality

00:13:36.020 --> 00:13:38.279
we had two strategies

00:13:38.279 --> 00:13:42.899
conservative strategy and ostrich algorithm

00:13:42.899 --> 00:13:45.070
which strategy do we take?

00:13:45.070 --> 00:13:48.290
neither of them are good

00:13:48.290 --> 00:13:50.490
20 years ago

00:13:50.490 --> 00:13:56.959
our goal was to create the software, somehow

00:13:56.959 --> 00:13:59.930
having computerized system is the power

00:13:59.930 --> 00:14:05.490
it is so powerful, the computer itself is
so powerful, comparing to the human creation

00:14:05.490 --> 00:14:06.190
??(00:14:05.13)

00:14:06.190 --> 00:14:12.550
so it has great power, so software development
was pretty expensive back then

00:14:12.550 --> 00:14:14.480
the computers were expensive

00:14:14.480 --> 00:14:16.720
the network connection was expensive

00:14:16.720 --> 00:14:21.850
the failure never be allowed in that age

00:14:21.850 --> 00:14:26.720
so they needed to optimize, not to fail

00:14:26.720 --> 00:14:28.390
at the cost of satisfaction

00:14:28.390 --> 00:14:33.850
so I don't care you are satisfied our software
or not

00:14:33.850 --> 00:14:40.850
but I can re-use some kind of the power of
computers with that computerized system

00:14:42.600 --> 00:14:44.100
so everyone was dreaming

00:14:44.100 --> 00:14:48.190
we believed that the only way to create software

00:14:48.190 --> 00:14:52.060
we tried hard to believe that was the only
way

00:14:52.060 --> 00:14:54.270
but 20 years later, now

00:14:54.270 --> 00:15:00.020
our goal is not really, not just create a
software

00:15:00.020 --> 00:15:02.810
our goal is to create the great software

00:15:02.810 --> 00:15:09.810
you know, nowadays everyone has computer,
everyone uses software

00:15:09.920 --> 00:15:15.330
so, mere possession is no longer the power

00:15:15.330 --> 00:15:17.529
everyone has computer, everyone has software

00:15:17.529 --> 00:15:19.880
so we're saved

00:15:19.880 --> 00:15:24.839
to differentiate, to have the power over others

00:15:24.839 --> 00:15:30.209
we need to create great software, we need
great software

00:15:30.209 --> 00:15:36.520
we got to create great software, but how?

00:15:36.520 --> 00:15:38.670
of course we don't know

00:15:38.670 --> 00:15:40.279
we have made false assumptions

00:15:40.279 --> 00:15:42.360
admit our ignorance

00:15:42.360 --> 00:15:46.899
but, but there's good news, there's good news

00:15:46.899 --> 00:15:49.200
the computers are cheaper

00:15:49.200 --> 00:15:52.110
cloud computing is even cheaper

00:15:52.110 --> 00:15:54.769
a network connection is cheaper now

00:15:54.769 --> 00:15:55.610
and ubiquitous

00:15:55.610 --> 00:15:57.019
everyone has imagination

00:15:57.019 --> 00:16:00.300
even in this room

00:16:00.300 --> 00:16:01.959
software development is cheaper

00:16:01.959 --> 00:16:04.260
comparing to twenty-something years ago

00:16:04.260 --> 00:16:08.660
so, we can be more productive, more abstract

00:16:08.660 --> 00:16:12.149
and we now have better tools and a better
language

00:16:12.149 --> 00:16:19.149
like Ruby

00:16:24.720 --> 00:16:26.980
and we have a lot of open source software

00:16:26.980 --> 00:16:29.360
so we can rely on that kind of software

00:16:29.360 --> 00:16:31.339
we can learn from that software

00:16:31.339 --> 00:16:38.339
so, old days, it is quite difficult to study
from the real source source code ?? (00:16:41.91)

00:16:44.529 --> 00:16:50.620
if you would like to learn about the operating
system

00:16:50.620 --> 00:16:57.620
so you cannot access to the source code of,
say, Microsoft Windows

00:16:59.810 --> 00:17:04.579
or the ?? (00:17:00.68) or some other operating
system

00:17:04.579 --> 00:17:09.179
you, you can access through Linux?? (00:17:08.34)

00:17:09.179 --> 00:17:12.409
or the very old version of Linux

00:17:12.409 --> 00:17:15.269
but not the real software

00:17:15.269 --> 00:17:18.010
but nowadays you can access the Linux

00:17:18.010 --> 00:17:23.209
a whole bunch of Linux code and you have tons
of operating systems

00:17:23.209 --> 00:17:27.420
and that is used in reality

00:17:27.420 --> 00:17:29.740
and

00:17:29.740 --> 00:17:33.960
you can use some software in your system

00:17:33.960 --> 00:17:37.299
you can learn from that source code

00:17:37.299 --> 00:17:44.299
so it's much easier for us to learn and create
the great software

00:17:46.710 --> 00:17:49.960
and we can now have the collaboration via
internet

00:17:49.960 --> 00:17:55.320
it's, it's changed the game

00:17:55.320 --> 00:18:00.320
so, 20 years ago, soon after I graduated the
university

00:18:00.320 --> 00:18:07.179
I was at the point I was working as a professional
programmer in enterprise software

00:18:07.179 --> 00:18:14.179
I was prohibit to write email abroad, outside
Japan

00:18:14.760 --> 00:18:18.220
only 20 years ago - not two hundred years
ago

00:18:18.220 --> 00:18:25.220
so, yeah, I, when I was a university student

00:18:26.100 --> 00:18:28.640
I wrote some kind of software, free software

00:18:28.640 --> 00:18:35.640
it was distributed by, it was quite minor,
you know client on top of ?? (00:18:32.73)

00:18:36.130 --> 00:18:43.130
and, I got to mail from some other guys, probably
in the States

00:18:43.700 --> 00:18:46.490
I don't remember quite

00:18:46.490 --> 00:18:47.730
but

00:18:47.730 --> 00:18:52.460
I tried to reply, and soon after that I got
error mail

00:18:52.460 --> 00:18:59.460
your company did not pay money to the internet
connection

00:19:00.450 --> 00:19:04.809
international internet connection, I mean

00:19:04.809 --> 00:19:10.370
so, I forwarded that reply to my friend in
the university

00:19:10.370 --> 00:19:17.370
the university pay that kind of bill so that
he could receive the mail

00:19:19.850 --> 00:19:23.490
it was quite awkward corresponding, you know

00:19:23.490 --> 00:19:26.720
he wrote mail to me then I did not respond

00:19:26.720 --> 00:19:30.710
so that, the friend respond because of me
or something like that

00:19:30.710 --> 00:19:37.710
but, you know, now we can connect to everyone
all over the world

00:19:37.980 --> 00:19:44.380
so we can access through Japan, China, Moscow,
everywhere

00:19:44.380 --> 00:19:47.750
so we can now collaborate over the internet

00:19:47.750 --> 00:19:54.750
so, that allows us to do some kind of social
coding, so

00:19:55.010 --> 00:19:59.350
so, GitHub changed everything

00:19:59.350 --> 00:20:06.350
so these good things bring up the new fantasy
land

00:20:07.049 --> 00:20:09.520
the new perspective

00:20:09.520 --> 00:20:16.520
so we can ignore gory detail of the hardware
or the

00:20:17.140 --> 00:20:21.840
and the new operating system, for most of
the cases

00:20:21.840 --> 00:20:28.030
we can stand on the shoulders of giants, so
we can use the great huge software

00:20:28.030 --> 00:20:35.030
of the operating system, framework, language,
the tools, editors

00:20:36.220 --> 00:20:37.419
so a lot of the things

00:20:37.419 --> 00:20:44.419
so we can do great things with very little
effort, comparing to the past

00:20:45.470 --> 00:20:52.470
so we can do greater work than our real ability,
real power

00:20:54.040 --> 00:21:01.040
so, I think the genius 20 years ago does not
recur enough, is not strong enough

00:21:04.919 --> 00:21:09.500
they are almost fame ?? (00:21:05.97), the
ability as a human, in genius

00:21:09.500 --> 00:21:16.080
but, now, we can rely, we can collaborate,
we can collaborate over internet

00:21:16.080 --> 00:21:22.929
we can collaborate on top of open source software,
free software, so

00:21:22.929 --> 00:21:26.200
we can do greater works than our past

00:21:26.200 --> 00:21:30.179
but that does not mean we are greater

00:21:30.179 --> 00:21:32.890
so the situation has changed

00:21:32.890 --> 00:21:38.040
we can have power, we can have more freedom

00:21:38.040 --> 00:21:40.870
we can have more joy in software

00:21:40.870 --> 00:21:47.870
so I remember that the, working on the enterprises
software was not fun

00:21:48.419 --> 00:21:55.419
so, it's quite boring, so translating human
sophistication

00:21:55.600 --> 00:22:01.360
in human language into the computer language
was so boring

00:22:01.360 --> 00:22:07.799
you know, that sophistication once said that,
OK, assign this value to this variable

00:22:07.799 --> 00:22:10.990
or something like that, so

00:22:10.990 --> 00:22:17.990
why these kind of genius don't write the code
by themselves?

00:22:18.870 --> 00:22:22.429
it was quite boring when I was ?? (00:22:49.51)

00:22:22.429 --> 00:22:29.429
so now, we can do by ourselves, we can have
joy in our programming

00:22:29.860 --> 00:22:31.740
it's kind of like engineers' heaven

00:22:31.740 --> 00:22:36.530
that's where we are, and that's why we are
here

00:22:36.530 --> 00:22:43.530
but wait, it's still not real

00:22:44.820 --> 00:22:49.720
in reality is as conflict as past

00:22:49.720 --> 00:22:55.650
so, who maintains this fantasy land?

00:22:55.650 --> 00:23:00.730
in reality, we cannot just ignore mess, so
we don't need

00:23:00.730 --> 00:23:07.730
something, so, we can ignore or just forget

00:23:08.980 --> 00:23:14.390
but something's got to maintain this kind
of a mess

00:23:14.390 --> 00:23:21.390
so, it's, so somebody's got to work on that
kind of mess

00:23:23.150 --> 00:23:25.080
garbage collectors

00:23:25.080 --> 00:23:29.160
no, that's not the garbage that you imagine

00:23:29.160 --> 00:23:36.160
for that kind of topic you can go to to the
Koichi talk

00:23:37.070 --> 00:23:43.500
so, by the term garbage collector, I meant
this (picture)

00:23:43.500 --> 00:23:50.500
and, we have to rely on this kind of people
in our daily life

00:23:51.990 --> 00:23:55.040
even in our programming

00:23:55.040 --> 00:24:00.410
without them, we would become mess

00:24:00.410 --> 00:24:02.809
so welcome to the desert of reality

00:24:02.809 --> 00:24:06.809
we rely on garbage collectors

00:24:06.809 --> 00:24:10.280
so we'd better appreciate them

00:24:10.280 --> 00:24:17.280
we rely on a lot of garbage collectors who
keep the fantasy land

00:24:19.320 --> 00:24:22.590
who created your favorite language?

00:24:22.590 --> 00:24:25.070
the garbage collector

00:24:25.070 --> 00:24:30.780
or, who created your favorite gems?

00:24:30.780 --> 00:24:34.820
gem creators, raise your hands

00:24:34.820 --> 00:24:38.429
you have to appreciate them (applause)

00:24:38.429 --> 00:24:43.669
thank you

00:24:43.669 --> 00:24:47.350
who created your favorite frameworks?

00:24:47.350 --> 00:24:54.350
who wrote your favorite books? book writers,
raise your hand (applause)

00:24:57.130 --> 00:25:04.130
who created your opensource software, we have
tons of open source software

00:25:05.750 --> 00:25:07.980
in and out our Ruby community

00:25:07.980 --> 00:25:09.440
so we have to appreciate them

00:25:09.440 --> 00:25:15.620
so appreciation and respect is the key, I
believe

00:25:15.620 --> 00:25:19.299
the key to the open source community

00:25:19.299 --> 00:25:22.240
the key to the moving forward

00:25:22.240 --> 00:25:24.460
so open source community is kind of like a
shark

00:25:24.460 --> 00:25:25.770
(laughs)

00:25:25.770 --> 00:25:32.770
we need to keep moving forward, or die

00:25:35.090 --> 00:25:36.730
(applause)

00:25:36.730 --> 00:25:43.730
so, we have to, and I would advise to you,
keep moving forward

00:25:44.960 --> 00:25:51.630
so you have to run as fast as you can to stay
in the same place

00:25:51.630 --> 00:25:58.630
and you have to run twice as fast as that
to move forward

00:25:59.039 --> 00:26:04.030
so run fast, try often, fail early

00:26:04.030 --> 00:26:08.020
keep moving forward, yes, that is my message

00:26:08.020 --> 00:26:11.630
and in addition, appreciation is not enough

00:26:11.630 --> 00:26:18.270
so, we are not creative to the gem writers

00:26:18.270 --> 00:26:22.679
we are not creative to the language designer

00:26:22.679 --> 00:26:29.150
we are not creative to the open source software
programmers

00:26:29.150 --> 00:26:32.289
so we became one

00:26:32.289 --> 00:26:39.289
so, take the red pill

00:26:41.950 --> 00:26:45.210
so, you can come join us

00:26:45.210 --> 00:26:49.690
if you are a programmer, that's fine, that's
fine you're a programmer

00:26:49.690 --> 00:26:54.539
you take a great step to create something

00:26:54.539 --> 00:26:57.210
you know, the programmer is a creator

00:26:57.210 --> 00:27:04.210
so, you create software, then by your creation

00:27:05.530 --> 00:27:09.720
the world will be better, I hope, I really
will hope

00:27:09.720 --> 00:27:12.880
the world will be better by your creation

00:27:12.880 --> 00:27:18.450
you programmers, you create soft ware, and
you make the world better

00:27:18.450 --> 00:27:25.450
but, but you might still living in the fantasy
land

00:27:27.690 --> 00:27:31.910
which is kept by the garbage collectors

00:27:31.910 --> 00:27:37.020
and if you're willing, I'm not forcing you

00:27:37.020 --> 00:27:40.490
if you're willing, you can be one of them

00:27:40.490 --> 00:27:44.630
you can be a garbage collector

00:27:44.630 --> 00:27:46.710
you don't want?

00:27:46.710 --> 00:27:49.309
but this garbage collector is much cleaner

00:27:49.309 --> 00:27:56.309
so, be a garbage collector, take part in keeping
the fantasy land

00:27:56.840 --> 00:28:03.840
so this fantasy land, unlike the first one,
which ignores everything

00:28:04.860 --> 00:28:11.860
so this fantasy land, we currently enjoy is
our result of the effort of the long time

00:28:15.570 --> 00:28:20.350
maybe twenty, forty, fifty years of the great
effort of the garbage collectors

00:28:20.350 --> 00:28:27.350
so, I, I invite you guys to take part in keeping
the fantasy land

00:28:33.809 --> 00:28:38.640
and for example, so you can join the CRuby

00:28:38.640 --> 00:28:45.640
even in writing some reporting some issues
the bug trackers or something like that

00:28:46.840 --> 00:28:53.840
so, once you know what we garbage collectors
doing behind the CRuby

00:28:54.980 --> 00:29:01.980
you can take the, that session

00:29:04.049 --> 00:29:11.049
so, again, so I ask you to create a great
fantasy land

00:29:18.140 --> 00:29:25.140
currently we enjoy, and it can be even greater
with your effort

00:29:25.330 --> 00:29:30.570
so you can do as much, many things, so writing
software on top of Ruby on Rails

00:29:30.570 --> 00:29:32.220
or the ?? (00:22:49.51) or something like
that

00:29:32.220 --> 00:29:39.220
that will enrich the community and communicate
with blogs, twitter and social net, social

00:29:41.580 --> 00:29:41.929
coding

00:29:41.929 --> 00:29:48.929
or even, participate in the community, like
the GitHub is our friend

00:29:49.990 --> 00:29:55.150
you can do many things, submit bugs, write
documents on the

00:29:55.150 --> 00:29:58.159
you know, have a presentation in the conference,
you can

00:29:58.159 --> 00:30:05.159
or, write a small piece of software, write
a part in the, submit a ?? (00:31:05.62)

00:30:05.240 --> 00:30:11.260
so, so many things you can do, but in any
way create

00:30:11.260 --> 00:30:16.179
and try to keep a great fantasy land that
we enjoy

00:30:16.179 --> 00:30:16.929
change the world

00:30:16.929 --> 00:30:23.929
so, I believe we've changed the world in better
ways

00:30:24.690 --> 00:30:29.230
in the past, say, ten years, so

00:30:29.230 --> 00:30:33.110
a lot of people in this conference, in the
past Ruby conferences

00:30:33.110 --> 00:30:40.110
so presented the great things, so now I expect
even more great work will be introduced in

00:30:44.510 --> 00:30:48.200
this conference

00:30:48.200 --> 00:30:55.200
so do not be a just a listener

00:30:55.360 --> 00:31:01.190
do not be a passive receiver of information

00:31:01.190 --> 00:31:08.190
so you hear something in this conference,
you learn something, take action

00:31:11.270 --> 00:31:12.909
change the world

00:31:12.909 --> 00:31:19.029
so, this is the key of the open source community

00:31:19.029 --> 00:31:25.390
this is the key of the Ruby community, so

00:31:25.390 --> 00:31:29.250
I know myself, I'm not a great programmer

00:31:29.250 --> 00:31:36.250
so, especially the Ruby commuters in the league
knows I'm not a great programmer

00:31:40.080 --> 00:31:42.440
I create so many bugs

00:31:46.240 --> 00:31:56.620
but, but still, I could, I did great job that
influenced the world

00:31:57.140 --> 00:32:03.770
and I respect myself by changing the world
better

00:32:03.770 --> 00:32:09.400
so I believe you can do that too in someways

00:32:09.400 --> 00:32:10.809
so change the world

00:32:10.809 --> 00:32:11.150
thank you

00:32:11.150 --> 00:32:11.809
