[RapaFan]

Take off your coat NERD!

[perkelation]

ctrl+opt+cmd+8 !

[gmdtvh]

Is node actually capable of replacing PHP? Shit, I just learned the language, and Zend Framework ... Well it looks hust great. JS is awesome. Now Ryan, can you tell us please which is the most suitable framework for node? Is it Spine or something else?

[karankent]

An off-topic question.. what is the music track at the beginning of the presentation?

[tobiasartz]

Great talk! Node.js is probably going to be THE web2.0 back-end language. Bye bye PHP.

[joeydanielallen13]

Try holy buddha instead of Jesus

[jbperez808]

Great to see Ryan has gotten a lot more confident at public speaking nowadays. One of his first public talks was rather difficult to listen to because it was peppered with uhhs and mmms.

I do find this talk much more pleasant to watch and in fact it was very compelling and interesting.

[csmath30]

Ryan,

I have no doubt you are a very smart guy. However, your presentation is very confusing and it seems your were unprepared. If you want to makert this stuff, you need to deliver clearly on your presentations. Just a suggestion.

[wafflejock]

@nicpro85, PHP is interpreted as is JS, PHP interpreter and libraries are written in C, my guess is V8 the javascript VM used here is also written in C. I don't think PHP is crap is a valid statement, but this should be considered as a viable alternative. Javascript running in V8 in some circumstances can end up executing faster than similar compiled C due to the optimizations built into V8 (that is pretty amazing). This is just another example of pick the right tool for the job (and skills).

[gshauger]

I wish the camera would have shown the nerd who made the Windows comment....some basement dwelling virgin

[nicpro85]

is PHP crap? i dont understand

[NewYork81983]

ok sooo....is it really cold in there?

[miXn]

@NewYork81983 Made my day.

[Centersphere]

I tried to interrupt, but he didn't respond to my question :(

[webinfornet]

Estou espantado com esta tecnologia

[gamersma]

The guy dosn't know shit about PHP and yet he talks like he's got it figured out... His statement was maybe true like 6 years ago... ignorance...

[MoritzMyer]

thanks for that

[clray123]

59:00 tracing data flows instead of tracing control flows is a bitch. it's an anti-pattern sort of thing that you really want to avoid for most of your code. speaking from experience in developing multi-threaded client software (with event loops and tons of callbacks, of course). the async continuation style of programming might look like a new cool invention to boys, but in terms of ease of comprehension and debugging it's vastly inferior to the traditional blocking procedural approach.

[IAmRyanCoke]

Whats the music at the beginning?

[yopizza]

Wow the guy is fun! I really enjoyed the show!

[tennistechie]

The example of deeper and deeper anonymous functions starting around minute 48.00 totally reminds me of the movie Inception. A dream within a dream within a dream. And then the callback cb that he added is totally like the totem that you need to carry around as you go deeper into this anonymous world to remind you.

[kszpirak]

Love it. This guy for president. He doesn't **** around.

[Snyflex]

Like someone says down there, great talk wrong audience. Its a cool technology! Im going to play with it now to see what i get.

[Zoasterboy]

i'm in luv

[DaSheep]

great talk, wrong audience..

they don't get how awesome that is. :(

[strictlykev2008]

@DaSheep Hindsight is 20/20

[DaBigNob]

Node looks amazing and quite useful and even something fun and interesting to explore.

But as to this presentation itself , I couldn't get past the repetitious usage of "ok so" "ok so" "ok so" "ok so" to fill the gaps of silence while the presenter mentally prepared his next train of thought!

How about a cliffs notes version of the presentation that chops out all the OK So's? LOL

[makrusak]

6 persons are not programmers

[moveaxebx]

"cat /etc/passwd"

"rm -rf"

I LOLed.

[cantoraz]

Cool!

BTW. What the name of colorscheme you used for the Vim or iTerm?

[OopsAiee]

Event-based engine is a cool idea for developers, the trouble is it won't double up the hardware. Once you need not make a thread (or care about everithing else) the engine is making it for you.

Meaning? This approach is nice if project load is not huge - on the huge load you will be bottlenekked faster.

[bainsbeant]

@OopsAiee Look up the C10K problem. The best way to write a server that can handle lots of connections (thousands) is not with threads. The idea with node.js and other asynchronous non-blocking libraries is that you don't need a thread per connection. A thread is a terrible thing to waste on a single blocking connection. Put your non-blocking connection file descriptors in epoll, kqueue or what have you and let the OS notify you when data is available. This eliminates context switching.

[OopsAiee]

@bainsbeant One may write a pool with async sockets with a main loop and this will work in any existing languages. In other words write yourown event handler - thats all. I don't say this technology is bad I say it's just the same thing but from other point of view. It's uniq so far and interesting but I would not switch blinded to node just because it's new and been good advertised. The cons against using it is a different development paradigm. Once must code with async handling in mind.

[Ediblelies]

I have no understanding of what he's explaining but I want to. Why aren't schools teaching the young creative knowledge that allows life to be simplified, such as this? I feel more inquisitive & less educated. The only thing I know how to do with a computer is turn it on & use the Internet. Being this ignorant to a highly rapid world is terrible. Maybe I was just born during the wrong era?

[KeepItFresh02]

whats wrong with php? :/

[dzagent]

The intro music is great... just like Node.js.

[Fiotee]

The red part on his shirt looks like a gun laser scope, lol.

[onurbabadeluxe]

Sry if a ask.... but i mean php is a serverside scripting language and js a clientside scripting language... why is js better than php? they're Two Different Animals?

[dubrox]

@onurbabadeluxe Node.js allows to run javascript server-side so now it can "compete" with PHP and other server-side languages.

Said that, every language has advantages over others, and some people find themself more comfortable with one or another. Evidently many users here prefer scripting in JS instead of PHP, that's it.

[MrSandervanDoesburg]

@onurbabadeluxe node.js is asynchronous and php is not. So when you need to read a file from the disk php waits for the disk to spin and read it and then php goes further with the script. Node.js creates a callback that executes when the file has been reads so it doesn't wait until the file is read but goes further with the script immediately.

[andrija11]

4 php developers dislike this video

[dreampeppers99]

someone has this video? because this is offline at least now 08/26/2011 16:52 GM-3

[CodeRarity]

Control-Command-Option-8 to invert colors =P

[shalpin]

Great talk, I thought Ryan was an interesting presenter, his enthusiasm really comes across.

[MrBTie]

I don't get it. The php people are laughing of their own disgraceful situation?

[rkulla]

@MrBTie PHP developers have to laugh at themselves. It really is the Windows of the programming world. I should know, I've done it for a living for years. Just like Windows, it technically "works" in a sloppy, unsafe--yet easy, way; but really can't beat the well designed opponents.

[MrBTie]

@rkulla great to hear it from someone who actually used it. once I was decided to learn php, then I read the first chapter of a book about variables assignment and declaration in php. "oh god, why a thousand rules just for saying a=1??? php musnt be good" It's the first item of my 'never-gonna-learn' list.

[digerpaji]

@MrBTie what disgrceful sitution i dun get. If he is dissing PHP then he is a fucking retard

[MrBTie]

@digerpaji then search about it on the internet. php good ol'days are behind.

[Nolgthorn]

@digerpaji Can you spell properly? Yes, the creator of node.js is a fucking retard and PHP, a language that is 17 years old is not out of date. You are right about everything how does it feel to go through life being so right all the time?

[boltar2003]

Is there any particular advantage to using this over python other than language preference?

[MrBTie]

@boltar2003 yes. it's faster and different. it's also good for programmer experience. It's not like any other famous framework out there, be it rails or django.

[fengmk2]

After fuck the GFW, I saw this video finally.

[JasonBunting]

It's great that Ryan Dahl created Node.js, and this was a decent enough intro, but it would have been nice if he were a bit more professional in this demo, he's not very polished... And the swearing was pretty lame. How old is this guy?

[cccallum1]

@JasonBunting: Swearing is a tool that can be used to intimidate or demean people, or it can be used to relieve tension and create a sociable atmosphere. I don't think the second type is lame.

[JasonBunting]

@cccallum1 Amazingly, one can "relieve tension and create a sociable atmosphere" without swearing, too. And depending on the audience, swearing, even for this purpose, can make some people feel the opposite. I work with a lot of very professional people, some of which are a bit more conservative about that kind of thing, and it would cause problems - i.e. I can't show this video to such people, unfortunately.

[cccallum1]

@JasonBunting It's a shame about some people being so conservative, but it's their loss. And most professional people I know enjoy swearing. I know it's possible to be casual without swearing, but that doesn't mean everyone always should.

[glabega]

Great job! Awesome introduction to note

[xXxEmogal999xXx]

34:15 lolol very mature.

[Crisboot]

Awesome!

[SeventhFlow]

his moving so much from left to write sorta irritating...

[fiffirt]

What's the intro music?

[zigomir]

cat /etc/passwd

[joeyco67]

Very informative demo. Love it.

[someonerules]

I can't believe I watched that whole thing... I mean, it was awesome and all, I just didn't know I was capable of watching a presentation for an hour.

I guess Ryan is just that damn captivating.

[bezudar]

@someonerules Shucks!! It was for an hour. i dint even notice..wow

[MrNightLifeLover]

Why should I love gdb? It's buggy and absolute horror to debug C++ with stl!

[emarcs81]

Very interesting stuff, I''ve been following this project for some time.

There's an "automated" way to compile nodejs on Archlinux, just use yaourt on the aur repository. Just type: yaourt -S nodejs and you are ready to go.

Ryan is a funny guy.

[bricestacey]

This is a great introduction to node. Thanks, Ryan.

[ardc0rre]

great talk :)

oh and actually Ryan confused himself around 32:00 when he was testing 'delete a[n]'. he was right upfront, delete in JS does not remove the element from array, it changes it to undefined instead. if he'd check array's length he'd see that it's not touched. it seems that for some reason node repl is not showing such elements (that was the confusing part).

[d0m0x]

I <3 his terminal style...

[DrewLeSueur2]

Invaluable

[minhajuddinkhaja]

I think it is vividchalk by tpope.

[mtgred]

What is the Vim colorscheme Ryan uses ?

[attomostube]

@mtgred AFAIK you need to edit your /usr/share/vim/vimrc (if you are using Mac) and Ryan, he use iTerm.

[DmitrijSohin]

“Windows is very important. Just like php.” 1:18

[frosty1433]

@DmitrijSohin I understand Windows is love/hate, but what's wrong with PHP?

[petsoukos]

@frosty1433 Nothing. Just because someone expressed a personal feeling it doesn't mean it's wrong.

[JasonBunting]

@frosty1433 What's wrong with PHP?! Hmm, where do we start? You could start here, and keep going:

bit.ly / php-sucks-but-it-doesnt-matter (sorry, I had to obfuscate the link, *&@#^$!! YouTube doesn't let you link to outside resources, apparently.

[frosty1433]

@DmitrijSohin oooh I get it. this replaces php. lol

[katalysis]

@DmitrijSohin I also like "cuz Macintosh is shit."

[wangchao19890207]

@DmitrijSohin That's mean, but I like it

[yopizza]

@DmitrijSohin Apparently, that was a PHP meeting. Cheeky!

[RecycleEmotions]

@DmitrijSohin Oh f***

[nicpro85]

@DmitrijSohin i dont understand is PHP crap ?

[tonyparisi1]

Thanks Ryan, big node fan here.

[dannycastonguay]

Thank you..

[beardymonger]

Awesome, and without slides! 

[zyrgzyrg]

Very interesting.

[AlicanC]

Cool.
