06:26	sfisque	cem__ not directly, but you can execute a method in a backing bean that performs the check for you
06:36	cem__	i thought sessionscope removing means removing entire session :/ i was wrong good jsf :/
06:36	cem__	only that managed bean is removed
06:41	sfisque	sessionscoped persists while until teh user session is invalidated
06:41	sfisque	s/while/until
06:41	sfisque	headn to bed. be well and code strong

09:26	cem__	#{obj.m1(1,2,3,4,5,6.....))}
09:26	cem__	??
09:27	neuro_sys	about time planning on a career change perhaps
09:48	sajjadg	neuro_sys, audio embedded steganographic image!!!??? :D good one
09:50	neuro_sys	wait, oh
09:50	neuro_sys	you're in the other channel too I see

11:17	phao	Hi. Why would someone choose something like node.js over java ee? I mean, besides the general tendency of going with the dynamic languages.
11:17	phao	I knwo very little of both, btw. Unfortunately. I wanna learn the 2, and I'm doing that, but currently, I'm kind of clueless.
11:18	neuro_sys	I guess to be a full stack dev, using the same language for both backend and frontend?
11:19	phao	That's it?
11:20	phao	I was thinking that it maybe would be something more profound.
11:20	tjsnell	we use javaee and 0 front end java
11:21	neuro_sys	what's the gain with being profound
11:21	phao	neuro_sys, nothing really.. it's just that node.js got so much attention that I thought there were somethings profound about it.
11:22	neuro_sys	I don't know much either, maybe there's more to it
11:23	tjsnell	there isn't a general tendency for dynamic language either
11:23	phao	tjsnell, isn't there?
11:23	tjsnell	http://www.tiobe.com/index.php/content/paperinfo/tpci/index.html
11:23	phao	Oh, yes, but it's not about being used now.
11:24	tjsnell	what?
11:24	phao	It's just that lots of people want to do it over a statically typed language.
11:24	tjsnell	source?
11:24	tjsnell	I'm showing you data
11:24	tjsnell	you show me your data
11:25	phao	I don't really have it. I just hear about it in lots of places.
11:26	tjsnell	my data trumps your anecdotal observations :)
11:26	tjsnell	perhaps you tend to look only in places that favor dynamic languages :)
11:27	phao	I'm not sure. It could be.
11:28	phao	I guess it's just the hype. Like with nosql databases stuff.
11:30	acuzio	NOSql database is not hype ; neither are dynamic languages.
11:30	neuro_sys	I really dig json/xml over the wire only approach, as in SPA.
11:30	CJ_	I'm currently running node.js for my frontend js and html and tomcat for my backend java servlets. So both can be used.
11:30	neuro_sys	managing ui/app state in the server is kindda weird, and stupid.
11:30	acuzio	neuro_sys: absolutely
11:31	acuzio	CJ_: node.js for frontend JS ?
11:31	acuzio	There is no such thing as FrontEnd node.js
11:31	CJ_	acuzio, Any recommendations for learning NoSQL? Moved to mongo and still trying to learn the ins and outs.
11:31	tjsnell	he's talking multi levels
11:31	CJ_	acuzio, I'm hosting the js on node.js
11:31	acuzio	Mongo is good
11:31	tjsnell	node to serve the front end
11:32	acuzio	Why would you want to do that ?
11:32	tjsnell	Mongo is web scale
11:32	CJ_	tjsnell, Exactly.
11:32	phao	tjsnell, hehehehehe
11:32	phao	acuzio, why do you say they're not?
11:32	CJ_	acuzio, Because it allowed us to easily work on the front end without having to continuously redeploy.
11:33	CJ_	tjsnell, The trouble is that mongo isn't like a relational db, which is what I'm used to. So I still have that mindset when using mongo.
11:33	acuzio	CJ_: So node is just being used to "serve" JS+HTML
11:33	CJ_	acuzio, Yes.
11:33	acuzio	phao: Because they are not - there is a lot of unwanted hype but that happens across the board
11:33	acuzio	CJ_: meh
11:33	phao	I see.
11:34	CJ_	acuzio, meh?
11:34	tjsnell	nginx++
11:34	acuzio	tjsnell: really
11:34	acuzio	apache+vagrant - sorted
11:34	CJ_	I like nginx, but I've only used it as a reverse proxy.
11:34	acuzio	s/vagrant/varnishd
11:35	acuzio	rigth laters ladies better get back
11:35	phao	tjsnell, btw, that data is kind of weird because of how little it ranks js.
11:36	* tjsnell	shrugs
11:37	tjsnell	it's a well known source and widely used
11:37	tjsnell	it is data, JS will rank higher on different data I'm sure
11:38	phao	http://langpop.com/
11:40	tjsnell	see
11:40	tjsnell	still top 2 static, 3 of the top 5
11:40	phao	Yeah. The issue is that afaik, this wasn't even close to true 5 to 10 years go.
11:41	phao	It's growing. Maybe it reached max. now, but that doesn't seem to be the case.
11:41	phao	this === dynamic languages on "the top" like shown in that langpop graphs
11:42	phao	I mostly do statically typed languages. So I'm kind of out of the world of dynamic languages, unfortunately. I only did scheme, but that was pretty isolated.
11:43	phao	s/years go/years ago
11:43	phao	=D
11:48	tjsnell	can't imagine doing any web apps and not being at least decent at JS
11:48	tjsnell	even with using some java framework
11:48	tjsnell	never deployed one that didn't require some custom js tweaks
11:50	phao	I see. I remember people users of gwt saying the same thing too.
11:51	phao	I shouldn't generalize. I was talking to only 4 gwt developers =D
11:52	tjsnell	5 now :)
11:52	phao	hehehehe
11:52	tjsnell	it was the case in a GWT I deployed also :
11:52	tjsnell	was my first and last one :))
11:52	tjsnell	actually liked it a lot
11:53	tjsnell	but now I like going straight JS instead
11:53	phao	I see. Reminds me of vanilla.js
11:54	tjsnell	vanilla is an improvment over jquery but still requires too much DOM manipulation/interaction
11:54	tjsnell	AngularJS is where it's at :)
12:01	fabioportieri	every js framework will require dom manipulation because that's just what js is about. angular and others mvw js framework delegate their dom manipulation stuff to subcomponents like jqlite, (a lite version of jquery)
12:04	fabioportieri	my point is: mvw frameworks are not better then prototype,dojo,etc just because you don't need to manipulate the dom, they don't do it because their purpose is to create a webapp archetype, but for a full fledged rich webapp you will still have to manipulate the dom, with jquery or your preferred low level js library
12:05	fabioportieri	or raw js, if you like pain
12:11	tjsnell	fabioportieri: no shit
12:11	tjsnell	of fucking course that's the case
12:12	tjsnell	the point is, the DEVELOPER
12:12	tjsnell	doesn't have to muck with the DOM virtually ever with angularjs
12:12	tjsnell	my point is, the code is massively cleaner, easier to understand and easier to test
12:13	tjsnell	I've deployed Angular apps into production that had zero code that manipulated the DOM directly

17:16	acuzio	tjsnell: This is a big point - most people dont understand that YOU as a developer don't have to manipulate the DOM by hand - this is a BIG FUCKING change.
17:20	Guest66321	when we use SVG ?\
17:21	sfisque	anyone recommend a java lib that will handle FLR, delimited, AND excel format for import/export? i'd like to leverage one lib if i can. i know i can glob together several libs to do it
17:23	whartung	FLR?
17:24	sfisque	fixed length record
17:24	sfisque	i can find ones that handle 2 of the three in different combos, but none that handle all three
17:26	semiosis	angularjs <3
17:26	sfisque	i guess i glom 2 libs together
17:26	semiosis	came across this on twitter the other day: http://alicialiu.net/leveling-up-angular-talk/
17:27	semiosis	lots of good stuff for the intermediate angular dev to level up

18:12	Guest66321	i'm getting afraid of maven and pom.xml
18:12	Guest66321	very strange way !
18:12	Guest66321	ALIEN
18:18	tjsnell	exciting
