Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,trying to say
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,the final point I'm trying to make is

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,good for writing cloud services back-end
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,service it's good for being well this is
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,debatable but those people who have
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,written in go think it's actually quite
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,simple to read and understand it's good
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,for having this thing funny thing called

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,I'll talk about in a while it's got
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,fantastic concurrency and my favorite
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,feature its Java done right it's

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,ignore the funny fmt in the capital case
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,it's not a class print line it just goes
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,way of denoting a public variable you
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,see it's pretty much the same across
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,many many different languages so goal is
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,somewhat familiar and therefore somewhat
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,easy to learn in fact go about design to
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,be easy to learn anybody who comes from
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,a Java environment or c-lite language
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,will find go somewhat familiar go is
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,definitely type safe I like to I like to
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,put up this example do you think this
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,come this program will run do you think
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,this program will compile really compile
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,it won't even compile let's try how many
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,of you have run your presentations
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,before I'm going to run the presentation
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,and let's read their messages go error
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,messages are not too bad actually
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,so what it's done is taken this HTML fed
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,it into a temporary file called compiled
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,0 dot go and the compiler complained
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,cannot use B type string in an integer
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,for assignment can you do in JavaScript
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,yes or no yes let's prove it and you put
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,down a microphone
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,so I is definitely okay thank you my
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,anything so I is definitely an integer
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,now I is a string
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,javascript is bad truffles I'm starting
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,a flame war here actually not true
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,javascript is a pretty good language now
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,in a godo so let's talk about go alright
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,this one is not so obvious how strongly
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,typesafe is go
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,why type safety at all but let's let's
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,look at this code and let's see whether
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,it will compile at all
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,I declare a type called mynum as an
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,integer and over here I declare a

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,assign it the value two over here I
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,assign a variable J of type int integer
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,of value three can I assign I and J in
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Java cannot can in ogs definitely can

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,look at error message

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,very very strongly typed and this is
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,very useful if you write big code if you

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,now how do I know there is a method this
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,funny syntax which go created the way
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,you read this line means quantify is a

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,returns an integer that's how you read
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,it so basically it's a matter of my
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,string it says print that means printer
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,screen quantifying s and was s its

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,that simple code for that so let's cut

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,well this code were let's go to line by

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,declaration syntax so a variable Q is of
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,type quantifier that's why it means it
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,is not quantifier is of type 2 it's the
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,other way around so variable Q is of
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,type quantifier so the quantifier has a
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,quantified method Q equals my int 3 now

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,make it my it so I'm casting 3 to my end
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,think of it like a constructor in Java
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,so that's a constructor kind of thing
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,print queue 25 so 3 is a numeric it's
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,positive so should be 1 I guess so
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Q equals my string ABC and the length of

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,sort of right and how is it different
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,from the Java interface well I like to
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,think go start the refers Java copied it
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,but here that's actually a very good

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,circumvent that problem by anyway let's
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,go to goes the feature which I want to
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,talk about which is concurrency which is
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,something which for a person new to

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,quite hard as well so over here I
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,declare a function let's call plus and
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,all it does for event however prints
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,the plus sign that's all it does after
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,one second it Blin prints another plus

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,dot okay
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,most of us when we start out writing

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,one compiled so
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,let's run it like this this one compiled
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,it all it's got some real error message
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,about to execute select so I'm about to

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,something in NGO called a goroutine and
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,his detected deadlock and its crash the
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,program and it's exited so okay let's
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,make the program work
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,let's fix me ok let's run + let's run

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,programmer I would do that of course

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,let go any time to run it all okay I am
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,the creator I'm the right of this
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,program now dot can run correct yeah
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,don't runs by one go and plus and dot to
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,run at the same time how do I do that
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,anybody we got go experts here come on
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,ah yes the goalkeeper do ah start a go
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,routine let's do that
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,I added three characters g/o and a space
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,and I've turned a regular routine into a

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,block let's prove it hey it doesn't
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,block it works but hold on this part the
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,code is not executing this particle
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,which says about to execute select is
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,not executing how do I get that to
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,execute as well
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,oh you guys are learning fast
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,put another make dot a go routine so
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,let's do that
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,bang now there's something interesting
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,here this comes from printing lying go
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,concurrency this comes from about to
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,execute select and then the pluses and
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,dots what is actually happened here is
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,the program ran put that into the
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,background it's running independently in
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,the background put that in a background
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,that took a few hundred microseconds
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,fraction of a millisecond so in a
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,fraction of a millisecond or maybe a
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,millisecond later the print line
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,executed and I needed to put this select
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,here select here select is a statement
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,which actually tries to determine which
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,grow routine is ready to run but if I
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,remove that select if I remove the wait
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,forever what do you think will happen
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,the program would actually the program
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,would terminate
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,what happened to my goal routines if
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,main terminates the core routines
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,dominate let's prove that
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,so no more select it's commented out and
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,by the way the double slash if you've
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,not figured it out its comment
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,program exited no dots no plus so that's
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,another feature of go
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,it has garbage collected the goal
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,routines goal is a garbage collector

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,performant garbage collector those
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,people coming from Java every now and

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,to be like that as well stop the world
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,for a few hundred milliseconds the

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,really stop the world alright
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,those people who know JavaScript will
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,know no js' that's nothing new
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,no Jas has concurrency as well so let's
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,prove it I'll put it here
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,f12 to get console
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,so over here I've defined two JavaScript
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,functions function plus and function dot
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,and this is very JavaScript every 1000
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,milliseconds lakh to the console a plus

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,console a - no - a dot so when I run
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,that well pluses go on to pluses four
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,pluses five pluses go on and on
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,if I run dot if I can type
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,now you got plus and dot's so javascript
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,can do what go to us mind budget if you
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,know JavaScript do you want to learn go
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,okay was it the same sort of sort of the
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,same what I just did in my in my web

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,good question
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,let me attack let me attack the first
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,question first let me address the first
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,question first go binaries can get
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,pretty big pretty fast that hello world
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,was about one to two megabytes why is it
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,so big why is a hello world almost two
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,megabytes
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,yes when you write a Java class
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,HelloWorld in Java class and the class
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,file is a few hundred bytes a go
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,executable is a few megabytes almost two
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,megabytes but the Java file can run on
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,its own you need the JVM which is 50
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,megabytes or more the last time I
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,checked the entire JVM for go the entire
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,go runtime is embedded in the binary the
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,entire go runtime the handles go
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,routines the entire go runtime that does
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,all this smart implicit interfaces
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,entire go runtime that does strong
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,static types is embedded in that one or
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,two megabytes in the hello world so most
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,go binaries are self-contained most HTTP
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,is not self-contained but you can make
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,it self-contained and can make a pure
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,coding net HTTP or the net library
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,actually makes use of the operating
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,systems resolver library which means
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,it's a time I'm a clear link library and
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,many pure go operas don't like it so
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,they turn off see go and you can produce
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,a pure goal binary and that consumes
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,maybe about five megabytes to eight
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,megabytes the entire web browser
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,resolver stack so that's why gold
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,binaries can get big quite fast the
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,entire docker binary was written in go
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,and it's about fifty megabytes I think
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,right so really really huge projects
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,like docker kubernetes cube control cube
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,CTL they win roughly tens of megabytes
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,when you deploy a goal binary in a
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,docker container I don't use Alpine
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,because I guess I just used from scratch
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,in docker terms from scratch means start
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,with an empty container empty docker
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,container and in my go binary is five
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,megabytes my docker containers five
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,megabytes really tiny docker containers
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,so the mantra for goal is don't
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,communicate by sharing memory right
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,don't communicate by sharing memory
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,share memory by communicating so
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,everything in goal is independent and
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,unshared non share you communicate
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,across different processes using
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,channels any other comments questions
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,reactions if not I think Xiao Zhang yes
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,yes I've used a patch a benchmark to
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,test the let me repeat the question for
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,the audience the question was is go now
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,because that hello world was static
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,content static web browsers everybody
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,knows it's blazingly fast right any any
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,person can write a fast static web
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,browser the question was is go the right
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,tool for IO intensive dynamic content
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,and absolutely that's the purpose of
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,goal it's designed to have very very
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,fast io intensive stuff if if everything
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,is compute intensive like video encoding
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,go will not be very effective because
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,the compute or CPU resource hungry
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,process will grab the CPU but if it is
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,IO intensive go is the perfect fit much
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,much much better than no GS know GS
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,rocked the world because it multiplexed
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,a lot of i/o intensive process
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,on two one thread go multiplex the same
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,thing actually cause some copy no GS in
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,their sense but knock not one trip on
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,all available threads if you have a 64
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,core CPU 64 processes can be called the
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,task versus one process in no js' and
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,yet that yes ok take two days
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,I'll just because need ok
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,go good for writing back in service
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,. go is fantastic for writing back-end
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,service second question is cool
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,resource-hungry does go require a lot of
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,resources like Java for example in the
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,answer is no go is very very efficient
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,next to see in terms of efficiency if C
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,was the ghost and there is one it uses
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,100% go would use maybe of 110% maybe
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,hundred five percent so it is very very
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,resource efficient thank you
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,[Applause]
