00:00:06.370
wait hi hi everybody my name is Michael
00:00:11.360
and as yesterday I come from Singapore
00:00:15.260
you can find me on twitter my twitter
00:00:17.840
handle is kota kung fu and i also
00:00:20.300
tweeted engineers for the win I am
00:00:24.079
currently a software engineer at the
00:00:25.910
sigma power this basically the digital
00:00:29.090
technologies team there were building
00:00:30.829
some digital products for the for the
00:00:32.660
company so my topic today is about what
00:00:36.320
about Ruby on Rails from a PHP guy I
00:00:38.960
guess from the topic you can guess I am
00:00:41.600
the PHP guy a bit more about me
00:00:46.480
basically I started coding in PHP back
00:00:49.010
in 20 2001 and I started a single PHP
00:00:52.370
user group back in 2007 the user group
00:00:55.460
right now is celebrating its 10th
00:00:56.929
anniversary and that's me with creator
00:01:01.579
of PHP Rasmus laid off when he was in
00:01:04.339
Singapore in 2015 for the pitch becomes
00:01:07.010
Asia which is also a conference that I
00:01:10.010
ran that's us in 2015 but in 2014 I
00:01:16.250
joined a consultancy called new
00:01:18.020
innovation and that's where I started
00:01:20.060
coding Ruby and Ruby on Rails and since
00:01:23.960
then I've been an active member of the
00:01:25.460
Ruby community in Singapore that's us
00:01:28.370
the current batch of the tech ladies
00:01:30.590
bootcamp we're working on a project for
00:01:33.470
the appoint NGO called Mountbatten
00:01:35.510
vocational school yeah and that's me
00:01:39.890
Matz when he was in Singapore for the
00:01:42.050
riddle Ruby conf last year sorry the
00:01:44.990
photos be blurry cuz I had a bit too
00:01:46.850
much drink and
00:01:48.310
you know yeah I think she do this with
00:01:50.350
celebrities but you know yeah so for me
00:01:55.060
as a PHP guy switching from PHP to Ruby
00:01:57.430
and to be real rose to be honest wasn't
00:02:00.759
really that hot in a sense I started my
00:02:03.430
developer life as a web web designer
00:02:05.189
back when formatting web pages with
00:02:07.899
tables was cool you know this no he's
00:02:11.860
coming back really no anyway so I've
00:02:17.590
been building web applications in
00:02:19.120
cakephp and colon cancer for about ten
00:02:22.330
years
00:02:23.110
cakephp itself was inspired by the MVC
00:02:26.019
pattern pioneer by the by Ruby on Rails
00:02:28.890
so what about the languages that is both
00:02:32.200
and we see frameworks were built upon
00:02:33.700
right so having been coding in PHP for
00:02:36.730
more than ten years searching ruby was
00:02:38.950
really quite an interesting experience
00:02:41.489
let me just talk a little bit about the
00:02:43.810
similarities that I find in both
00:02:45.910
languages Ruby and PHP bona fide to
00:02:48.940
present languages they're dynamically
00:02:51.160
typed the easy to understand one reason
00:02:54.310
I think one reads the English and the
00:02:56.320
other one okay not so much both
00:03:01.170
object-oriented and yeah this is tester
00:03:06.609
yeah objected last I remember yes this
00:03:09.790
too is the differences father difference
00:03:12.519
is related to PHP IDs
00:03:15.700
how many PHP developers here I mean were
00:03:17.709
PHP developers or osteo PHP developers
00:03:20.139
quite a few yeah represent anyway um no
00:03:23.380
PHP promise very beginning so as a web
00:03:25.600
centric kind of language whose main for
00:03:28.180
building websites it works very well
00:03:29.500
with Apache web server it's not quite a
00:03:32.200
language in the sense it's more like
00:03:34.180
collection of functions but in PHP seven
00:03:36.910
they we have been some concerted effort
00:03:38.620
to kind of put it together and get act
00:03:40.299
together and make it more like a
00:03:41.560
language which is good
00:03:45.620
and right Wes Ruby is a general-purpose
00:03:51.230
language it's more and it's the more
00:03:54.650
effort there's a bit more the making
00:03:56.569
making web web enabled and it's very
00:03:59.540
expressive language as I've stated
00:04:00.800
earlier so some of the syntax
00:04:03.260
differences we do to like on the left
00:04:05.030
you have how you declare string in PHP
00:04:07.540
number and the different numbers and
00:04:10.040
sorts of off and variables you always
00:04:12.230
start with dollar sign an object a
00:04:14.930
variable we have a dash greater than and
00:04:18.109
so and so forth
00:04:19.959
Ruby is pretty much close to the same
00:04:23.870
like local variables you don't need to
00:04:25.880
put a dollar sign anywhere a global
00:04:27.530
variable Depot dollar sign and you don't
00:04:30.500
need use a dash greater than to refer to
00:04:32.990
variable set and methods and arrays they
00:04:39.650
have arrays in PHP and raised in Ruby
00:04:43.550
and hashes Ruby and if-else statements
00:04:52.130
in PHP a ruby and this is how you
00:04:56.270
declare a class in PHP like class class
00:05:00.260
T extends beverages same thing on the
00:05:03.560
right as so that's how a ruby yeah and I
00:05:08.419
like the fact that with Ruby class all
00:05:12.470
you do is yeah do private hear the rest
00:05:16.070
of it of stuff below our private methods
00:05:17.930
which is kind of nice where Ruby where
00:05:22.310
Ruby wins I think is in areas where you
00:05:26.900
don't need a semicolon at the end of a
00:05:28.520
statement you know I've been bitten so
00:05:30.889
many times but sometimes I write some
00:05:32.720
Ruby and I kind of like the maintain
00:05:34.820
some PHP code and then why is this cold
00:05:37.010
feeling alright I left our semicolon
00:05:39.070
right happens to us all dot is not used
00:05:44.389
for concatenation like future you could
00:05:46.280
put dot the Concannon concatenate two
00:05:48.080
lines two strings rather
00:05:51.039
in Ruby you don't need to Kali methods
00:05:54.279
you think you come at this with one less
00:05:56.379
character you know like you know you
00:05:58.629
yeah yeah you Ruby just dot something
00:06:01.899
and in PHP gotta dash greater than you
00:06:05.740
know one less character that's that's
00:06:07.749
right less typing on the keyboard you
00:06:09.789
know can you bracelets are not always
00:06:14.319
necessary you know and what opening text
00:06:18.509
you do the opening text in oh yeah oh we
00:06:22.300
don't need that in Ruby right that's
00:06:24.219
great what I think other things that
00:06:27.550
like Ruby tooling tooling supports great
00:06:30.490
testing profiling debugging this is not
00:06:33.309
like afterthoughts in Ruby a few in PHP
00:06:36.159
is well like oh wait we need to do some
00:06:37.719
testing yeah how do you do that
00:06:40.889
dependency management is pretty easy you
00:06:43.089
know bundler of course in PHP we now
00:06:45.430
have composer which also just the same
00:06:47.349
thing but you all know that compose the
00:06:49.360
Kyle copied from where bundle came from
00:06:51.909
right so yeah easy switch between Ruby
00:06:54.909
the versions which is great
00:06:56.199
Robby lrvm we can move between different
00:06:59.020
versions in PHP is a bit harder I think
00:07:02.050
and do that we're in our some Apache
00:07:04.509
config or something composure 24 ini
00:07:06.729
files but it's not as straightforward
00:07:09.870
and open source community is pretty
00:07:11.889
awesome right so problems are we are
00:07:14.169
lost smart people the Ruby community and
00:07:15.759
it has solve a lot of problems that we
00:07:17.289
face ourselves
00:07:20.389
and yeah so that's Ruby hobo Ruby on
00:07:23.539
Rails why what do I like about it so
00:07:27.219
there's no need to depend on a separate
00:07:29.389
web server for development so let's
00:07:30.830
build a web server in where do rails new
00:07:33.020
and has poop I'll install you know that
00:07:34.849
it's pretty great what we receive is web
00:07:36.500
brick a PHP leak out that quite recently
00:07:39.800
I think 5.40 introduced a testing server
00:07:41.900
billion but it's not as good as what we
00:07:44.750
have in the rails community
00:07:47.479
come on interfaces out pretty awesome
00:07:49.520
although you can say darrell has
00:07:52.099
something similar but it's not as easy
00:07:53.990
to read easy to use tracking DB's
00:07:58.069
changes is pretty straightforward
00:07:59.810
relatively easy usually there's a gem
00:08:04.039
for that when you have a problem there's
00:08:05.900
usually a gem which is great right
00:08:08.919
awesome
00:08:12.430
rails is a little very and be friendly
00:08:14.750
so it's come you can use log commonly
00:08:17.000
use stuff
00:08:18.050
all right probably use things you do you
00:08:20.270
can probably find a gem you know this
00:08:21.889
gem for that and for ideas to product
00:08:24.050
you can get it out in a very short time
00:08:25.669
and that's great it's relatively secure
00:08:28.190
and out of the box
00:08:32.029
they also many development about
00:08:33.680
deployment options like Heroku or Azure
00:08:36.199
I went to a self-hosted VPS it's pretty
00:08:38.570
straightforward
00:08:41.409
that's my repo one of my repo strata and
00:08:45.560
you can see most small ivory projects in
00:08:48.350
there right now 10 PHP projects so some
00:08:54.050
of the projects I've actually worked on
00:08:55.250
on my own my own with using Ruby on
00:08:58.010
Rails this is engineer so SG which is AI
00:09:00.769
I created to basically I create a group
00:09:03.949
to go around different tech meetups in
00:09:05.990
Singapore to come over I call it the
00:09:07.250
meetups because I feel that there's a
00:09:10.640
lot of talks happening in Singapore
00:09:12.769
different user groups and I felt it was
00:09:14.630
good there was no way to kind of like
00:09:16.370
like no one is actually keeping track of
00:09:18.079
them or recalling those two videos so I
00:09:20.839
thought I was always contribute back
00:09:22.339
because I have some knowledge a video
00:09:24.529
editing and videography and all that
00:09:26.510
stuff so I thought it'd be great for me
00:09:28.160
to try this so I've been doing this for
00:09:30.589
the last three years
00:09:31.360
recording meetups at first and
00:09:34.220
more recently conferences so the last
00:09:36.530
two radar we conference was actually
00:09:38.210
recovered by me and quite a few other
00:09:40.940
things that iOS called what cam and
00:09:44.860
DevOps days and few others so the whole
00:09:48.500
site was actually built in Ruby on Rails
00:09:49.990
I think that foot I did the first cut of
00:09:53.810
the website over a weekend it was a
00:09:56.330
weekend hack put together a small site
00:09:58.670
initially it was a reader I think just
00:10:01.010
to the YouTube channel and a car like
00:10:02.840
hey we need to come up with a nice page
00:10:04.790
for this yeah the front end is rails I
00:10:07.370
used active admin that for the back end
00:10:08.780
to make changes to things that's pretty
00:10:11.630
easy as after a while because I was also
00:10:15.050
uploading love videos and a lot of the
00:10:17.090
tasks that I do for uploading files to
00:10:18.980
YouTube was was tedious so I came up
00:10:22.100
with this modular website too for my
00:10:23.660
volunteers who also upload the videos
00:10:25.250
themselves so I built a little engine
00:10:27.380
SSG upload site it was unreal she was on
00:10:31.190
a VPS running and generics passenger and
00:10:33.770
because he was I was handling some large
00:10:35.540
files it was like four five sometimes
00:10:37.100
uploading to three gigs of four gigs of
00:10:39.110
files I need to use an engine X power
00:10:41.630
block modules account handles who flash
00:10:43.580
files of course the processing and
00:10:46.370
building and over there setting him out
00:10:48.140
to YouTube and processing the file was
00:10:49.820
all done using sidekick pretty pretty
00:10:52.370
easy so I cut bill this over a couple of
00:10:55.670
weekends but again it was very easy to
00:10:58.520
get up and running up MVP and currently
00:11:02.420
the project I'm working on for the
00:11:04.810
techies boot camp was also built on Ruby
00:11:07.400
on Rails
00:11:08.570
this is back she actually a website for
00:11:10.220
mountain bathroom vocational school
00:11:12.380
so basically be a student management
00:11:14.600
system for the for the school so that
00:11:15.980
they can take cube shahu the students
00:11:18.650
that goes through the school these are
00:11:20.630
students the students are pesky children
00:11:25.790
with disabilities like autism or
00:11:29.080
visually handicapped and we basically
00:11:31.280
the school basically brings them train
00:11:33.230
them for hospitality jobs like food
00:11:36.560
preparation FMB and housekeeping so
00:11:39.620
basically the school prepares them for
00:11:40.940
that and for the longest time they have
00:11:42.950
been doing a lot of these things in on
00:11:44.300
paper so as part of project for tech
00:11:46.250
need is really building a
00:11:48.260
student management system for them some
00:11:53.120
of the downsides of although I talked
00:11:55.190
about a lot of good things about Ruby on
00:11:56.390
Rails but there's some downsides to it
00:11:59.500
was serving web static or static content
00:12:02.420
you have probably have to bring your own
00:12:03.740
web server to do that it's quite rare
00:12:07.190
intensive but probably you just usually
00:12:10.070
solve about twenty more machines at a
00:12:11.480
problem
00:12:11.930
so lots of money troll just spin up the
00:12:14.510
Dinos and all that stuff that usually
00:12:16.370
solves problem write some reflections so
00:12:22.610
what I mean for me it was a deliberate
00:12:24.860
decision moving into the picking up Ruby
00:12:27.290
and Ruby on Rails for me if I only knew
00:12:30.560
PHP if all this PHP is audio a tall
00:12:34.010
order
00:12:34.370
only if P Spears only language I know
00:12:37.570
it's kinda like a hammer and everything
00:12:40.580
I see is a nail right knowing more tools
00:12:42.650
just give me my options and ability to
00:12:44.570
determine what is the best tool for the
00:12:46.280
job so basically everything we whatever
00:12:53.450
language we use these are based merely
00:12:55.160
tools for building great websites and
00:12:57.430
great web apps knowing more tools give
00:13:00.560
us the ability to decide on which are
00:13:03.560
the better tools to use for the job on
00:13:07.460
top that knowing not knowing different
00:13:09.800
languages all different frameworks is
00:13:11.660
one thing is far better know to have
00:13:14.390
better deeper knowledge in design
00:13:15.650
patterns in understand so that we can
00:13:17.900
understand how well do how we should
00:13:19.520
better build web apps we can also you
00:13:24.320
can actually write seven thousand lines
00:13:25.910
of spaghetti code in Ruby as well so so
00:13:29.270
knowing design patterns help you design
00:13:31.400
your code better such days more
00:13:33.350
maintainable and easier to make changes
00:13:36.510
so if you're if you own any of you I
00:13:39.000
don't know where any of you here seen
00:13:40.440
you do this if you are this some
00:13:43.019
resources I'd I personally try and went
00:13:45.779
through and was very helpful to me
00:13:47.699
try Ruby the real sky real skills guide
00:13:51.110
will be a real tutorial Rio's cast has
00:13:54.209
been all data but the videos are pretty
00:13:56.220
kind of a soup really good of course if
00:13:59.220
you are interested go for the one for
00:14:01.079
the Ruby Meetup you can meet like-minded
00:14:02.820
people as well yeah so that's me
00:14:07.620
Kotaku and then Gina's for the win thank
00:14:10.709
you thank you so much Michael so glad
00:14:17.490
you've seen the lights of rails
