Then why not just have an int?[00:45:11] <cyth> zmanning_, your mail header: Content-Transfer-Encoding: quoted-printable[00:45:40] <zmanning_> cyth: im sorry what about it?[00:45:45] <surial> fannagoganna: myVar++ instead of myVar.increment(). And you can use BigInteger if you need arbitrary number sizes; you'd have myVar = myVar.add(1);[00:45:57] <fannagoganna> with an int in a map, i would have to get the key (value corresponding to int), then increment that int value, and then store (put) this kay/value mapping into the map[00:45:59] <cyth> zmanning_, read the wiki[00:46:13] <fannagoganna> ah ok, bigInteger acts like a counter?[00:46:37] <fannagoganna> i don't require the concurrency features of AtomicInteger or AtomicLong, etc.[00:46:52] <surial> fannagoganna: Any number can act like a counter. You're going to have to be a bit more specific about what you are expecting.[00:47:02] <surial> fannagoganna: If you need a mutable integer, then just wrap an immutable anything into an object.[00:47:15] <surial> fannagoganna: A common hacky way to do it is to make an array of size 1. There are nicer ways.[00:47:36] <surial> fannagoganna: stop.[00:47:38] <surial> fannagoganna: Your plan doesn't work.[00:47:39] <fannagoganna> right, the nicer ways is what i am thinking of...[00:47:39] <cybereal> fannagoganna: Atomic* use CAS optimization for the concurrency feature, in other words, unless you have an old cpu, it's practically free, so it's just convenient to have a mutable primitive wrapper as standard[00:47:43] *** mistik1 has joined ##java[00:47:50] <surial> fannagoganna: You can't mutate objects that serve as keys in a map and expect the map to work properly.[00:47:57] *** zacs7 has joined ##java[00:47:59] <surial> fannagoganna: The only way to mutate a key object is to take it out, and then re-insert it.[00:48:11] <_W_> fannagoganna, what's wrong with get-increment-put again?[00:48:33] <surial> _W_, cybereal: Stop. Reread the entire stream. fannagoganna is trying to use a mutable object as a key in a hashmap. The entire principle is wrong.[00:48:44] *** oxi has quit IRC[00:48:54] <zmanning_> cyth: yea i pieced that together after reading it, the only thing is that thunderbird isnt picking up the characters in my content[00:48:54] <fannagoganna> extra step. Plus, say I have a Map<String, AtomicInteger>. When I run map.get(key).incrementAndGet(), it does increment the value associated with key.[00:49:01] <_W_> surial, you read again[00:49:12] <fannagoganna> simplicity of code is why i like the shorter way[00:49:12] <surial> oh, you're using them as values.[00:49:20] *** zacs7 has left ##java[00:49:20] <_W_> fannagoganna is contradicting himself - a histogram has the counter as a value, not a key[00:49:22] <zmanning_> cybereal: yea thunderbird is reading thesubject line but not the content[00:49:26] <zmanning_> getting closer though[00:49:38] <surial> fannagoganna: Use AtomicLong, or if that isn't long enough, look for an AtomicBigInteger, and if that isn't there, roll your own BigInteger wrapper that does have an increment.[00:49:44] *** oxi has joined ##java[00:49:56] <_W_> I don't see why this needs so much thought. int does the job[00:50:15] <_W_> or Integer, since he's using a collection[00:54:28] <cyth> zmanning_, does it work if you send the mail as plain/text?[00:55:52] *** tazle has quit IRC[00:57:33] *** tazle has joined ##java[00:58:06] *** Copter has quit IRC[00:58:40] *** Epoch`_ has quit IRC[00:59:20] *** cyth has quit IRC[01:00:52] <cybereal> zmanning_: well the only clue I can really give you is that E9 is not a value utf-8 byte on its own, it's the unicode codepoint for é for sure, but encoded into utf-8, the quotedprintable version should look like the subject line, not what the body's doing[01:01:14] <cybereal> zmanning_: so maybe somehow whatever's generating the body of your email is not encoding java's internal data structure to utf-8, just keeping it as utf-16[01:01:26] <cybereal> but replacing values above 127 with quoted-printable artifacts[01:01:33] *** Ivellina has quit IRC[01:01:37] <cybereal> maybe try changing your charset to utf-16[01:02:27] *** latebind has quit IRC[01:04:23] *** G0-T0 has joined ##java[01:06:23] *** rlubke has quit IRC[01:06:43] *** blankthemuffin has joined ##java[01:09:12] <cybereal> I hate websites that, after they are finished loading, they relocate your cursor to the username box[01:09:34] <cybereal> because I start typing my username and then password before it's done loading, not realizing this is going to happen and BAM I'm suddenly typing out my password for any onlookers to see in the username box... doh[01:11:44] <`House`> my condolences :O[01:12:27] *** multiHYP has joined ##java[01:12:45] <multiHYP> how can i align Strings in drawString from Graphics2D?[01:12:59] <cybereal> math[01:13:21] <cybereal> there are methods to find out how big a string will be, in whatever direction you want, in there, someplace[01:13:27] <cybereal> you can use that to decide where to render it[01:14:15] <multiHYP> where are those methods?[01:14:41] <cybereal> ~~ multiHYP javadoc Graphics2D[01:14:41] <javabot> multiHYP: http://is.gd/iDGI [java.awt.Graphics2D][01:14:45] <cybereal> learn. to. read.[01:15:43] <multiHYP> cybereal: learn to respond properly, if thats your intention.[01:16:16] <cybereal> multiHYP: this channel shuns lazy asses who can't read docs themselves, so go on now, do your own work[01:16:36] <multiHYP> cybereal: have some manner![01:16:44] <r0bby> multiHYP: have some brains[01:16:46] <r0bby> :P[01:16:47] <cybereal> multiHYP: it is you who needs the manners[01:17:15] <r0bby> multiHYP: not reading the docs shows laziness,furthurmore, it shows you are inconsiderate![01:17:34] <r0bby> We help those who help themselves first[01:17:51] * multiHYP insulted instead of helped![01:18:02] <cybereal> multiHYP: you insulted me by not bothering to read[01:18:11] <cybereal> also you have ridiculous expectations of an IRC channel[01:18:16] <cybereal> this isn't some kind of customer service venu[01:18:18] <r0bby> We help those who help themselves first << you don't deserve it[01:18:21] <cybereal> unless you're paying me[01:18:34] <r0bby> venue cybereal[01:18:36] * r0bby ducks[01:18:40] *** sombriks has quit IRC[01:18:41] <cybereal> r0bby: typo r0bby[01:18:46] <r0bby> suuuuuuuuuuuuuuuuure[01:19:12] <multiHYP> r0bby: don't help, don't answer, dont[01:19:15] <multiHYP> insult!!![01:19:16] *** amz has joined ##java[01:20:01] <r0bby> multiHYP: apologies.

No, not really. Hence the 'amazing parser' bit.

That wasn't as useful as I'd hoped.[01:38:58] <`House`> thank you very much cybereal :) :)[01:39:05] <surial> I know a bunch of apache projects are all over xslt2, and they do a lot of java stuff.

However, the difference is very very tiny. I can't imagine you'd ever notice. Just do whatever makes the most sense, and if you really notice serious performance issues, run a profiler on it. I'd shit in a bag if changing the keys for a map from strings to integers would make an impact.[01:40:29] <cybereal> `House`: basically .hashCode() will be called on key to figure out which bucket to use, so that'll be called on every look up regardless of finding anything, and then .equals() will be called if the bucket's not empty once for every entry in that bucket, so at least one time for a key that's valid in the map[01:40:54] <cybereal> well yeah, and even if you switch you'll have to do something to map them anyway most likely[01:41:07] <cybereal> just because one is faster than the other doesn't mean it will be applicable to your needs heh[01:41:14] <pfn> bobbytek2, does anyone even use xslt2? :p[01:41:26] <surial> `House`: I'll summarize this stream of info for you: For practical purposes, HashMap is very fast.

wrong[02:25:38] <waz> when cybereal and I agree you are clearly wrong![02:25:42] *** teralaser has joined ##java[02:26:08] <illbeatu> then what's with all the "hiding business logic" "sessions" "database persistence" and what not?[02:26:13] <illbeatu> that doesn't sound like swing at all[02:26:45] <cybereal> illbeatu: uh people were writing gui desktop apps to access databases far more frequently than web apps to do the same before web apps became popular[02:27:01] <cybereal> illbeatu: and swing came about when that was still popular using tools like delphi[02:27:21] <cybereal> so writing a db backed application, or a rich client to a db based server/system is hardly strange[02:27:49] <cybereal> anyway I pity your brain's significant hardening with regards to these concepts...[02:28:19] <illbeatu> well.. this is what i read whenever i find some article about MVC[02:28:28] <waz> it's a way of life for Rails[02:28:30] <illbeatu> on sun. on springsource.

one isn't working out for you[02:28:53] <cybereal> illbeatu: you just happen to be hitting one small subset of applications of it[02:29:17] <reverend> there comes a point when you should just decide 'hey, i don't get this at all' and move on[02:29:31] <illbeatu> whatever.[02:29:41] <cybereal> illbeatu: most computing systems including applications in use consist of what can be described as numerous recursively embedded implementations of "MVC" it's just the idea of separating concerns and a specific strategy for doing so[02:29:48] <r0bby> waz: have you seen griffon?[02:29:50] <reverend> and you would have saved a lot of time if you'd just taken my initial advice of giving up in the first place[02:29:55] <r0bby> Pretty hard to miss[02:30:06] <illbeatu> so it's just some software engineering principle...[02:30:15] <r0bby> illbeatu: it's a good principle[02:30:17] <illbeatu> i wonder why it's so buzzworded.[02:30:32] <cybereal> illbeatu: for example, in a swing app that is a client to say a complex accounting system, something that could conceivably find its way onto the desktop of a loan officer...[02:30:37] <r0bby> illbeatu: if you do proper MVC -- you should be able to attach any "View" you want to your app and it would just work[02:30:40] *** uttumuttu has left ##java[02:31:21] <cybereal> illbeatu: the gui itself has an mvc, modal is the state of the GUI components/etc., view is the underlying windowing resources displaying what the library told it to based on the model, and the controller is the event handling system responding to and delegating events from the windowing system[02:31:44] <illbeatu> r0bby, you're saying if you define your backend well enough, any front end engineer using html dhtml actionscript applets swing whatever, can work with your stuff right?[02:31:48] <r0bby> illbeatu: think of event listeners as the 'controller'[02:31:55] <cybereal> illbeatu: then that whole mvc becomes the view in the client which uses the remote server as its model or maybe a local cache of data from that server, etc. etc. it's not something special for any particular kind of app[02:32:07] <r0bby> illbeatu: in theory yes[02:32:20] <cybereal> illbeatu: more to the point is that you wouldn't have to rewrite the backend to add a new front end[02:32:24] <r0bby> i should be able to (assuming i can get at the API) hook up a web ui[02:32:32] <r0bby> hell even a CLI interface if i wanted[02:32:56] <cybereal> anyway, enough software design history 101, I'm hungry![02:33:13] <r0bby> there are very well defined layers (tiers) in java ee apps[02:33:31] <r0bby> :)[02:33:33] <illbeatu> again, it sounds like server side stuff[02:33:36] <illbeatu> but what do i know heh[02:33:42] <reverend> not much[02:33:49] <r0bby> illbeatu: how old are you?[02:33:58] <reverend> none of this matters to someone who doesn't actually program[02:34:01] <r0bby> you're coming as a tad...naive[02:34:15] <illbeatu> i am. i went to school for computer science :/[02:34:26] <reverend> you should ask for a refund[02:34:46] <aTypical> reverend, don't be r0bby. :-P[02:34:57] <reverend> why not?[02:35:19] <illbeatu> so the front end has it's own little mvc world?[02:35:27] <reverend> i've got like 20 minutes until a poker tourney[02:35:29] <cybereal> I don't know, does every CS program even bother teaching these higher level application design concepts? it's not as if you n eed to know mvc to write a sorting algorithm[02:35:31] <aTypical> OK. You can be him.[02:35:39] <cybereal> illbeatu: it might![02:35:57] <cybereal> illbeatu: it might not even be all three parts, might just be the V and C and always remotely access the M someplace else[02:36:05] <cybereal> it might have two M's![02:36:09] <reverend> cybereal: no, but it should have given you enough understanding of basic design principles to understand why separation of concerns is important[02:36:18] <pragma_> lightweight?[02:36:20] <cybereal> reverend: I guess, I'd agree that that is ideal[02:36:22] <r0bby> illbeatu: the point of MVC is that you can revamp the UI[02:36:29] <pragma_> what's a heavyweight gui for java?[02:36:31] <illbeatu> i understand that part[02:36:32] <thunderbolt> cybereal: I don't think they formally covered any of the GoF design patterns in my CS classes, although the professor recommended purchasing and reading hte book.[02:36:46] <illbeatu> i don't understand why you'd include MODEL in swing development[02:36:49] <cybereal> pragma_: the term refers to the technique of rendering, where heavy = native widgets and light = java drawn widgets[02:36:53] <illbeatu> don't you just call the interface[02:36:55] <pragma_> oh[02:37:00] <pragma_> awt vs java[02:37:00] <r0bby> illbeatu: how the FUCK do you think your data is represented?[02:37:05] <pragma_> er, s/java/swing/[02:37:20] <illbeatu> it's not like i'm gonna implement some distributed search algorithm in swing[02:37:21] <cybereal> pragma_: basically, although swing is built on awt... but that's kinda coherent to look at it that way[02:37:41] <illbeatu> then just call it VC[02:37:43] <illbeatu> whatever[02:37:59] <reverend> you know best[02:38:49] <tazle> illbeatu: because Swing is particular about models not changing at ankward moments etc.[02:39:14] <cybereal> illbeatu: you're too hung up on dogmatic views of abstract concepts[02:39:20] <tazle> illbeatu: thus the general purpose model might not be useful as a Swing model[02:39:33] <reverend> illbeatu: you need to write code, a lot of it[02:39:33] *** G0-T0 has quit IRC[02:39:36] <reverend> then you'll understad[02:39:42] <Infinito-> illbeatu, you wish to skip learning everything else and only working with the interface ? you should have studied graphical design then...[02:39:42] <illbeatu> uh huh[02:39:56] <cybereal> illbeatu: swing itself is a model, it's a model of components which the libraries underneath draw on the screen. An individual component will have the MVC parts even, take a List which has a model that represents the contents. That model might be based on some other model depending on how you implement it[02:40:08] <Infinito-> and don't fool yourself, you need to understand all the rest before being in charge of only doing GUIs... And if you get to work in some place where you attain this position, your job won't be exactly designing the GUI(since there's graphical designer for that), you're just gonna implement what the designer tell you too, and also implement all the interface connections and logic with the other software components...[02:40:13] <reverend> you don't learn programming by dicking around whining about buzzwords that you don't understand[02:40:20] <reverend> you learn it by doing[02:40:33] <cybereal> ~soc[02:40:33] <javabot> cybereal, I have no idea what soc is.[02:40:37] <illbeatu> reverend, you don't know me[02:40:40] <cybereal> ~you're an idiot[02:40:40] <javabot> Yo momma's an idiot, cybereal[02:40:43] <reverend> sure i do[02:40:45] <illbeatu> and how much i've coded[02:40:50] <illbeatu> so. the argument ends[02:40:54] <reverend> i remember everyone that breezes through here[02:40:57] <r0bby> summer of code[02:40:58] <cybereal> illbeatu: if you dislike the way you've been interpreted then better represent yourself[02:40:59] <reverend> it's a curse[02:41:28] <reverend> the problem isn't MY familiarity with you, it's YOUR familiarity with me[02:41:44] <cybereal> ~soc is <reply>In computer science, separation of concerns (SoC) is the process of breaking a computer program into distinct features that overlap in functionality as little as possible.
