00:00:16.640
thank you um hi everyone um my name is
00:00:19.160
Yuki um I'm really happy to be here
00:00:21.160
today um I'm going to be talking about
00:00:23.640
20,000 technique that you can use to
00:00:25.359
make yourself more uh productive um let
00:00:28.199
me talk about myself um this is me again
00:00:30.720
um I'm on a ruby C I maintain a jam
00:00:33.719
called Kar which is a r p um I'm going
00:00:36.879
to creator of the D gam and basically
00:00:38.960
what it does is um if if you have any
00:00:41.280
Tyles in the in the method and it triy
00:00:43.920
to suggest suggest to you what it should
00:00:45.879
be so it it is basically the C before
00:00:48.280
Ruby so someone someone calls someone
00:00:51.360
calls this J C before
00:00:54.480
Ruby anyway um I work for a company
00:00:57.840
called pel uh we have access in
00:00:59.960
Singapore Sydney and toel um so if you
00:01:02.879
are interested in working a p uh just
00:01:05.119
let me
00:01:07.600
know um going back to the main topic um
00:01:11.000
before I really start uh I'm going to
00:01:12.600
speak really fast so I'm going to upload
00:01:14.840
the slides later so you can take a look
00:01:16.479
uh the slides later okay the first one
00:01:18.960
is actually actually from the diim jam
00:01:21.680
um if you install diim 1.0.2 you can
00:01:24.159
require uh dig mean experimental which
00:01:26.920
enables um dig me's experimental
00:01:29.479
features
00:01:30.400
uh let's take a look at this example
00:01:31.920
which is um there's a typle in the
00:01:34.600
instance variable name and what's going
00:01:36.799
to happen is really trying to call the
00:01:38.439
method on nil so you get an error but if
00:01:41.119
you require DET experimental um it try
00:01:43.479
to find the right correct um instance
00:01:46.280
Val man for you um let's also take a
00:01:49.799
look at this this example um you have a
00:01:52.320
hash and you want to get a value out of
00:01:53.920
it and there's a title in the key name
00:01:55.880
and you get a key key error but again if
00:01:58.360
you require dig experimental um it it
00:02:01.159
will try to um correct the wrong um
00:02:06.520
kire um another another example would be
00:02:09.360
something like this um notice there's a
00:02:11.239
typle in the word initialize and this is
00:02:13.440
tricky because you define the method
00:02:16.200
called initialize and what you really
00:02:17.560
call is new so it's really hard to
00:02:19.519
realize that there a typo but if you
00:02:21.920
enable dising experimental it will
00:02:24.319
display a warning so it's going to be a
00:02:26.160
little easier for you to notice that
00:02:28.400
that's a typo okay number four Bon
00:02:31.400
confli gels um it allows you to insult
00:02:34.480
gems in parallel using threads um by
00:02:37.519
default it set to one and let's say you
00:02:40.519
want install about 200 gems and it takes
00:02:43.360
about two three minutes actually uh but
00:02:45.800
if you set it to like 1610 it only takes
00:02:48.000
30 minutes which is a lot
00:02:49.959
faster uh the next one is U making a
00:02:52.280
request on real console um if you are on
00:02:54.800
real console you can actually make a
00:02:56.360
fake request to the controller by saying
00:02:58.840
after get path uh you can also say um
00:03:02.239
after post or after delete so this is
00:03:05.080
really handy if you want to process a
00:03:06.360
controller action okay the next one is
00:03:08.920
power set um let's say you have a test
00:03:11.840
and that's weding and you don't know
00:03:13.280
what's going on and what it does is uh
00:03:15.480
it displays um description social
00:03:17.920
messages for you so this is really
00:03:19.959
useful if you have a mysterious Val in
00:03:21.680
your test there's also a JavaScript
00:03:23.879
implementation so if you have a
00:03:25.280
JavaScript R project you should
00:03:27.440
definitely con using this to the next
00:03:30.280
one is what is is a watch command it
00:03:33.080
executes a command uh periodically uh
00:03:35.599
let's take a look at this example on the
00:03:37.720
right side I'm running R test and there
00:03:39.959
a filing test and on the left side I'm
00:03:42.120
going to change a file and save it and
00:03:45.280
in the watch command runs break test and
00:03:48.720
I and here now you can see green um
00:03:52.319
usually I have to stop emac and go back
00:03:54.680
to the terminal and run the test but if
00:03:56.879
you use watch you don't have to do that
00:03:58.680
uh which is great okay the next one is a
00:04:01.360
new thing of getf uh this is actually
00:04:04.519
new that uh new thing that came out last
00:04:07.879
week um which is called compassion heris
00:04:11.159
um I think you've seen something like
00:04:13.120
example on the right side which is quite
00:04:15.360
not right but if you set compaction
00:04:17.479
fistic to tr then the G will be a little
00:04:21.160
a little smarter to display uh the
00:04:24.759
deaths the next one is bre expansion um
00:04:28.000
I think you've uh most of you know that
00:04:30.919
uh you can use uh you can move a file by
00:04:32.919
using um MV but you can also use
00:04:35.320
something like this to move a file which
00:04:37.120
is a little shorter this is called
00:04:39.160
breast expansion and you can also use
00:04:41.600
this with a lot of more commands like
00:04:45.199
CP the next one is his stre um terminal
00:04:48.479
actually remembers um the command that
00:04:50.639
you ran before so if you said his stre
00:04:53.400
it's displays all the commands you ran
00:04:55.360
before and here you can see some numbers
00:04:57.440
and what you can do with them is that to
00:04:58.919
run a specific spe command that is
00:05:00.840
associated to that
00:05:02.360
number you can also say ban band to run
00:05:05.600
the last command that you just run like
00:05:09.240
this and sometimes you don't really
00:05:11.360
remember uh the whole command but if you
00:05:14.880
if you only remember the first or second
00:05:17.000
character you can say uh control r u in
00:05:20.240
this example I'm trying to run right
00:05:21.840
test something something something which
00:05:23.080
I don't really remember but I just but I
00:05:25.319
just have to hit control R and hit W and
00:05:28.000
then the terminal will give me that the
00:05:29.720
right command that I that I would like
00:05:31.240
to
00:05:32.680
run the next one is three it's like
00:05:35.120
losos but it also displays in the
00:05:37.080
directory tree uh so it so if you don't
00:05:39.360
know what's inside the directory this is
00:05:40.919
really
00:05:41.960
handy you can also find a file if you
00:05:44.240
use it U with uh
00:05:46.639
grip the next one is Agent uh it's a Cod
00:05:49.880
searching tool a similar to act but it's
00:05:51.960
a lot faster um here I'm trying to find
00:05:54.840
files which which have um the word leral
00:05:58.440
um and the results looks like pretty
00:06:00.560
much the same as what act provides but
00:06:03.520
it's actually a lot faster than act so
00:06:05.600
if you think Act is slow then you should
00:06:07.160
definitely consider using AG the next
00:06:10.479
one is HP Pi it's a it is basically a
00:06:13.160
ver version of curl like let's say I
00:06:15.520
make a request to Ruby jams and you get
00:06:17.639
a result like this which is not really
00:06:19.599
readable uh but if you replace Cur with
00:06:22.400
hdp then it as well pretty far the Jason
00:06:25.199
so it's it's going to be a lot easier to
00:06:27.440
read the Jason but sometimes you don't
00:06:30.360
want to install um HD P because it's a
00:06:33.120
python implementation and you don't want
00:06:34.880
to install python just to be able to see
00:06:37.240
Jon and that's when J command comes
00:06:40.319
really really
00:06:41.720
handy
00:06:43.280
um so how can we use it um you make a
00:06:46.919
cur request and you can just pass you
00:06:48.919
can just PPE the result to JQ it will
00:06:51.400
just pretty far result for you and
00:06:53.680
what's nice what's nice about this is
00:06:55.440
that uh if you want to know what's
00:06:57.000
inside dependences development it will
00:06:59.199
just filter the results so if you have a
00:07:02.039
really really jent result um you don't
00:07:04.039
have to like uh scroll down to the
00:07:05.879
bottom you can just say JQ like this
00:07:07.919
array or and this property something
00:07:10.080
like that so it's really
00:07:11.879
useful the next one is pigment ties
00:07:14.400
which is a syntax Ty written in Python
00:07:17.280
um I used to use more before but it's
00:07:19.039
not really pretty so um I started using
00:07:21.840
pigment ties so if you use it um it
00:07:24.199
colorizes what's inside file so it's
00:07:26.479
going to be a lot easier to read and I
00:07:28.639
have this area on my personal computer
00:07:30.680
so if uh so I don't have to think about
00:07:33.039
uh what command I should be using to
00:07:34.840
display colorized results so it's going
00:07:38.120
to be like
00:07:39.240
this um sometimes you go to stack F and
00:07:42.919
then copy p a command but you don't know
00:07:45.199
really what's what it's really doing um
00:07:47.759
in that case you can just go to explain
00:07:49.199
shell.com and pass that command and
00:07:51.520
hopefully it's going to explain uh what
00:07:53.520
it actually does it it's not actually
00:07:56.080
100% smart so sometimes it doesn't work
00:07:58.800
then this is open source project so if
00:08:00.639
you think you can improve then you can
00:08:02.240
just go to get and P Quest the last one
00:08:05.360
is shift it um sometimes you want to see
00:08:08.039
you want to see two windows side by side
00:08:10.080
but it's a little hard to adjust Windows
00:08:12.120
manually and what it does is if you hit
00:08:14.560
us uh certain command it will position
00:08:17.360
the window on the right or left on the
00:08:19.879
bottom or bot or top so it's really
00:08:22.960
useful if you want to see two thingss um
00:08:25.520
side by side okay that's the 20 Tails uh
00:08:28.479
that's it thank you so much
00:08:33.360
much
