Scala uptake has slowed a lot |
| 15:38 |
|
tjsnell |
still super fringe and java8 may just kill it |
| 15:39 |
|
pdurbin |
he's using https://github.com/scala-ide/scala-worksheet as a REPL in Eclipse, which is cool |
| 15:40 |
|
pdurbin |
(I think) |
| 15:56 |
|
pdurbin |
I dunno about super fringe... Twitter published Scala School - http://twitter.github.io/scala_school/ |
| 16:03 |
|
tjsnell |
if you look at any numbers measuring it's adoption it's very fringe |
| 16:03 |
|
tjsnell |
it's very cool but not widely used |
| 16:03 |
|
tjsnell |
even if a giant like Twitter uses it |
| 16:05 |
|
pdurbin |
sure |
| 16:07 |
|
acuzio |
tjsnell: its not cool - |
| 16:08 |
|
tjsnell |
sure it is |
| 16:08 |
|
tjsnell |
but it's also dangerous as hell and tends to folks being clever and writing unmaintainable code |
| 16:08 |
|
pdurbin |
the REPL he's using is great. It just puts the values to the right of the code as comments |
| 16:08 |
|
acuzio |
your definition must be different - Haskell is cool -., Scala is just retarded ., its a bad mix of a bunch of good ideas |
| 16:09 |
|
pdurbin |
acuzio: what don't you like about Scala? |
| 16:11 |
|
tjsnell |
you're tony aren't you!? |
| 16:12 |
|
acuzio |
pdurbin: it needs to decide what it wants to be - Haskell on the JVM , yes thats good or Lisp on the JVM - thats good as well , its a bit of both with the worst characteristics of bot |
| 16:12 |
|
acuzio |
Additionally, its not readable at all |
| 16:13 |
|
acuzio |
ever tried reading someone else's Scala code - good luck |
| 16:13 |
|
pdurbin |
certainly Scala is multi-paradigm (by design), allowing both object oriented and functional programming |
| 16:14 |
|
tjsnell |
~simple scala |
| 16:14 |
|
tjsnell |
oh damn |
| 16:14 |
|
tjsnell |
no javabot :( |
| 16:14 |
|
* pdurbin |
should set up a javaeebot :) |
| 16:14 |
|
tjsnell |
trait **->**->** {implicit def **->**->**[A, F[_, _], B](a: F[A, B]): *->*->*[A, F, B] = new *->*->*[A, F, B] {val value = a}} |
| 16:14 |
|
acuzio |
Multi-paradigm means everyone picks their own paradigm to write that shit |
| 16:14 |
|
tjsnell |
now that's readable! |
| 16:15 |
|
acuzio |
its the C++ problem - |
| 16:15 |
|
pdurbin |
or perl. I love perl :) |
| 16:15 |
|
acuzio |
No one knows what anyone else has actually written |
| 16:15 |
|
whartung |
I used to thnk perl was the bees knees back in the day, then I walked away from the code for 6mos |
| 16:15 |
|
tjsnell |
but you have to admire code where (_._) is valid syntax |
| 16:17 |
|
acuzio |
I once saw some code where the guy had written Java in Scala - his whole reason for choosing Scala was the REPL - |
| 16:17 |
|
acuzio |
that was the most sane usage i have seen |
| 16:18 |
|
acuzio |
This might also be because i do _boring_ enterprise work |
| 16:18 |
|

we may well dive headlong in to Java 8 with our new project |
| 18:05 |
|
pdurbin |
we're talking about skipping 7 :) |
| 18:05 |
|
sfisque |
we probably wont. not enough need for anonymous functioning (very little parallel processing, as well) |
| 18:06 |
|
pdurbin |
it's due out in the spring |
| 18:06 |
|
sfisque |
we'll just skip to 10 when they remove the primitive types :P |
| 18:07 |
|
tjsnell |
you're using 1.6 still!? |
| 18:07 |
|
sfisque |
previous rev was 1.6, new rev is 1.7 (we had to refactor some because 1.7 broke some stuff in the version of primefaces we were using) |
| 18:07 |
|
pdurbin |
we have a ticket to upgrade :) |
| 18:08 |
|
sfisque |
in the enterprise world, stability > "gee whiz" |
| 18:08 |
|
pdurbin |
sfisque: they put up a slide yesterday about how primefaces adoption has taken off in the last 4 years (since the project started) |
| 18:09 |
|
tjsnell |
no primefaces for me! |
| 18:09 |
|
sfisque |
yah. it's probably the best "third party" jsf impl |
| 18:09 |
|
tjsnell |
actually I'm doubtful to ever do much web side in java again |
| 18:09 |
|
sfisque |
feature rich, and it's getting pretty "bug free" |
| 18:10 |
|
sfisque |
what would you do then? even SOAP and REST are web techs |
| 18:10 |
|
sfisque |
and RC is kind of taking a beating atm |
| 18:10 |
|
tjsnell |
server side java all the way |
| 18:10 |
|
tjsnell |
presentation side javascript |
| 18:11 |
|
tjsnell |
angularjs of late |
| 18:11 |
|
sfisque |
right but what's the js calling? |
| 18:11 |
|
sfisque |
for data |
| 18:11 |
|
sfisque |
and session |
| 18:11 |
|
sfisque |
and other stuff |
| 18:11 |
|
tjsnell |
java |
| 18:11 |
|
tjsnell |
as I said |
| 18:11 |
|
tjsnell |
java on the server |
| 18:11 |
|
sfisque |
and those calls are still web |
| 18:11 |
|
whartung |
he's talking removing the presentation logic from the services, and pushing it all in to the JS web client |
| 18:11 |
|
tjsnell |
but no jsps, play, wicket etc |
| 18:11 |
|
tjsnell |
semantics |
| 18:11 |
|
whartung |
yea |
| 18:11 |
|
whartung |
they're "http" |
| 18:11 |
|
tjsnell |
i've clarified |
| 18:11 |
|
sfisque |
if it's talking http, you're still doing web |
| 18:11 |
|
tjsnell |
stop being a pedant |
| 18:12 |
|
pdurbin |
:) |
| 18:12 |
|
sfisque |
vs messaging or some other delivery |
| 18:12 |
|
whartung |
he could be using websockets... |
| 18:12 |
|
tjsnell |
web.... |
| 18:12 |
|
pdurbin |
he's talking about the front end being written in javascript, as oppossed to JSF or whatever |
| 18:13 |
|
sfisque |
aye but jsf isnt java. it's xml. if you want to get really pedantic, so it's not even java |
| 18:13 |
|
tjsnell |
I don't |
| 18:13 |
|
pdurbin |
yeah, let's not get pedantic :) |
| 18:13 |
|
tjsnell |
pedantic is just irritating |
| 18:13 |
|
sfisque |

| 18:13 |

ok, lets' devolve into sophistry instead :P |

* sfisque |
goes and hides |
| 18:14 |
|
pdurbin |
so those slides from last year have a lot of the same examples |
| 18:14 |
|
pdurbin |
he goes through the old way and the new way with lambdas |
| 18:14 |
|
pdurbin |
in his "robocall" examples |
| 18:15 |
|
pdurbin |
and then from lambdas to streams |
| 18:15 |
|
pdurbin |
it's all about streams :) |
| 18:15 |
|
pdurbin |
pipelines |
| 18:16 |
|
pdurbin |
I expect people will be happy to use lambdas in Java 8 |
| 18:16 |
|
sfisque |
as long as they don't create unreadable soup |
| 18:17 |
|
sfisque |
showing 1 line examples hides the danger |
| 18:17 |
|
pdurbin |
"write only" ;) |
| 18:19 |
|
sfisque |
aye but doing things like ( int, int ) -> { blah; } hides things like ( obj, obj, obj ) -> { tons of questionably thread safe modifications as well as side effects spread over many lines of code }; |
| 18:19 |
|
sfisque |
i remember when inner classes were added in 1.1 and it was "the new toy". tons of inexcusably complex or obtuse object graphs |
| 18:20 |
|
sfisque |
i'm guessing we'll see a couple years of crap code, before people "get over it", and dial it back to use it more smartly |
| 18:20 |
|
pdurbin |
new: Optional - http://download.java.net/jdk8/docs/api/java/util/Optional.html |
| 18:20 |
|
sfisque |
now that's nice |
| 18:21 |
|
sfisque |
no more NullPerson class building |
| 18:21 |
|
whartung |
In java 8, all I'll write is Lambdas. I'll builtd my own object system out of Java Closures and Lambdas…it will be Pure and Perfect! |
| 18:21 |
|
* sfisque |
hates nullObject definitions |
| 18:21 |
|
sfisque |
ROFL whartung |

|
sfisque |
well, time to fetch the spawnlings. ttys |
| 18:22 |
|
whartung |
safe journey |
| 18:23 |
|
sfisque |
i've often wondered, after they added Proxy in the reflect package, why they never built in a "nullProxy" |
| 18:23 |
|
sfisque |
until now i guess (Optional) |

"Using reduce() instead removes all of the burden of parallelizing the reduction operation, and the library can provide an efficient parallel implementation with no additional synchronization required." |
| 18:43 |
|
whartung |
yea |
| 18:43 |
|
whartung |
for when you want to sum up those arrays of 1M integers. |
| 18:43 |

whartung |
watch it peg all of your cores for a micro second. |
| 18:43 |
|
whartung |
that's very nice |
| 18:45 |
|
Fubar^ |
is that reduce only safe because sum is commutative? |
| 18:45 |
|
Fubar^ |
because of the .parallelStream i mean |
| 18:45 |
|
whartung |
yea |
| 18:48 |
|
Fubar^ |
for non commutative functions, is the non-parallel version left or right associative? |
| 18:48 |
|
whartung |
"yes" :) |
| 18:51 |
|
pdurbin |
"lambdas change the way you design libraries" |
| 18:51 |
|
Fubar^ |
the function must be associative so i guess the order is undefined |

|
whartung |
no kidding! |

"streams change the way you write applications" |

whartung -> nullObject … static instance of an object that has no sane state, but can at least allow method invocation without getting an NPE (can throw some other informative exception, offer a default unusable value (-1, null, "", etc.) |

pdurbin2 |
I do believe port 22 is blocked at this hotel. works fine at the HIlton. oh well |
| 21:49 |
|
sfisque |
22? |

pdurbin2 |

| 21:50 |
|
pdurbin2 |
usually, I ssh to my server where I have screen+weechat running with my pdurbin nick |
| 21:50 |
|
sfisque |
are you referring to the https urls? |
| 21:50 |
|
sfisque |
oh ok |
| 21:50 |
|
whartung |
so what did adam talk about pdurbin2 |
| 21:50 |
|
pdurbin2 |
whartung: lots of stuff. on my mind what he said about JSF (which we use) |
| 21:51 |
|
pdurbin2 |
he says JSF is great for "enterprise" internal applications that don't need to be pretty, don't need to be pixel perfect |
| 21:51 |
|
sfisque |
thats funny. i would argue the same thing, but not for the reason he specifies |
| 21:51 |
|
pdurbin2 |
but for consumer apps, he likes the idea of exposing everything via an API and using http://angularjs.org to build the front end |
| 21:51 |
|
whartung |
I don't know about pixel perfect, but I'd agree with him on that |
| 21:52 |
|
pdurbin2 |
does anyone have a take on Angular vs. Twitter Boostrap? are they basically the same? |
| 21:52 |
|
whartung |
twitter bootstrap as I understand it is just a CSS theme |
| 21:52 |
|
sfisque |
jsf renders fine for us. my beef with jsf is that it makes deep linking problematic unless you turn the page construction workflow backwards |
| 21:52 |
|
whartung |
Angular is a full boat property change framework in JS |
| 21:55 |
|
pdurbin2 |
whartung: no, there must be some javascript in twitter bootstap a well. right? someone added it to http://sourcefu.com and now it's more... responsive or whatever... looks better in a mobile browser. I don't think it's just CSS... |
| 21:55 |
|
* pdurbin2 |
looks at the commit: Switched to using Twitter Bootstrap, specifically the Spacelab theme fro... · 7f9aa7f · sourcefu/sourcefu.github.com - https://github.com/sourcefu/sourcefu.github.com/commit/7f9aa7f |
| 21:55 |
|
whartung |
oh, I dunno about that. I mean, I can;t really say, just my impression, but BS is just a style as I understand, not a component framework |
| 21:56 |
|
pdurbin2 |
whartung: huh. maybe you're right... |
| 21:57 |
|
pdurbin2 |
"optional JavaScript extensions" according to http://en.wikipedia.org/wiki/Twitter_Bootstrap |
| 21:57 |
|
pdurbin2 |
whartung: ok, and angular is full boat. MVC. I wonder if that's what Discourse uses... |
| 21:58 |
|
pdurbin2 |
huh. no... they use Ember.js: https://github.com/discourse/discourse |
| 21:59 |
|
pdurbin2 |
anyway, bootstrap is what we'd like to take a look at. to use in combination with JSF (IceFaces, I guess, what we use now) if we can |
| 21:59 |
|
whartung |
yea, it makes more sense in that context than angular for sure |
| 22:00 |
|
pdurbin2 |
session starting... "no slides. code is king" \o/ :) |
| 22:00 |
|
sfisque |
icefaces… blech |
| 22:02 |
|
pdurbin2 |
sfisque: you sound happy enough with primefaces |
| 22:02 |

Lincoln is praising https://github.com/arun-gupta/javaee7-samples |
| 22:06 |
|
sfisque |
from what i know, ice faces is a bad knockoff of PF. i'd say, if you're working on jboss stack, RichFaces is probably btter fit, but for GF, PF works nicely |
| 22:07 |
|
whartung |
nice pdurbin2 |
| 22:09 |
|
pdurbin2 |
they're showing a "batch" example: https://github.com/arun-gupta/javaee7-samples/blob/master/batch/chunk-csv-database/src/main/java/org/javaee7/batch/chunk/csv/database/MyItemReader.java |
| 22:09 |
|
whartung |
yea, that's going to be a nice feature. |
| 22:09 |
|
whartung |
maybe it can replace the kit I wrote 5 years ago lol |
| 22:10 |
|
pdurbin2 |
a sample "job" - https://github.com/arun-gupta/javaee7-samples/blob/master/batch/chunk-csv-database/src/main/resources/META-INF/batch-jobs/myJob.xml |
| 22:10 |
|
whartung |
interesting |
| 22:11 |
|
whartung |
mine didn't go that far |
| 22:11 |
|
whartung |
didn't need to paramterize the steps |
| 22:11 |
|
pdurbin2 |
looks like these are the docs: http://docs.oracle.com/javaee/7/tutorial/doc/batch-processing.htm |
| 22:11 |
|
whartung |
the internal classes had that, sorta, but not as meta data |
| 22:14 |
|
pdurbin2 |
they're highlighting @DataSourceDefinition http://docs.oracle.com/javaee/6/api/javax/annotation/sql/DataSourceDefinition.html |
| 22:14 |
|
whartung |
oh, icky |
| 22:15 |
|
whartung |
I mean, really |
| 22:15 |
|
whartung |
I get it, much of the meta data in an EJB app is perhaps a bit overkill |
| 22:15 |
|
whartung |
but the DS isn't one of them, frankly |
| 22:16 |
|
whartung |
you need out of band instructions to have the container admin add the appropriate JDBC Driver anyway, whats a few more lines to set up a connection pool |
| 22:17 |
|
whartung |
how busy is it there pdurbin2 |
| 22:19 |
|
pdurbin2 |
people are standing in the back |
| 22:19 |
|
whartung |
cool |
| 22:19 |
|
whartung |
"java is dead" |
| 22:20 |
|
pdurbin2 |
they're talking about schema generation, using example from (I think) https://github.com/arun-gupta/javaee7-samples/tree/master/jpa |
| 22:21 |
|
whartung |
schema generation is folly |
| 22:21 |
|
whartung |
IMHO |
| 22:21 |
|
whartung |
from JPA |
| 22:22 |
|
whartung |
it's a nice toy, demos well, but it doesn't work |
| 22:22 |
|
pdurbin2 |
heh |
| 22:22 |
|
* pdurbin2 |
looks at http://en.wikibooks.org/wiki/Java_Persistence/What_is_new_in_JPA_2.1%3F |
| 22:23 |
|
whartung |
"Entity Graphs - allow partial or specified fetching or merging of objects." nice |
| 22:23 |
|

wonders what TREAT option is. My cat enjoys TREAT options |
| 22:23 |

pdurbin2 |
on to JMS: https://github.com/arun-gupta/javaee7-samples/blob/master/jms/send-receive-simple/src/main/java/org/javaee7/jms/send/receive/simple/ClassicMessageSender.java |
| 22:24 |
|
whartung |
yea they cleaned that up a bit with Closers (or whtave they're called) |
| 22:24 |
|
pdurbin2 |
closures, lambdas, whatever |
| 22:24 |
|
whartung |
no, things that auto close resources like connections |
| 22:25 |
|
pdurbin2 |
oh |
| 22:25 |
|
pdurbin2 |
much less code in https://github.com/arun-gupta/javaee7-samples/blob/master/jms/send-receive-simple/src/main/java/org/javaee7/jms/send/receive/simple/SimplifiedMessageSender.java |
| 22:25 |
|
whartung |
you'll see in a sec |
| 22:25 |
|
whartung |
prescient! |
| 22:25 |
|
pdurbin2 |
:) |
| 22:25 |
|
whartung |
yea that's nice |
| 22:26 |
|
whartung |
NOT THAT IT MATTERS! |
| 22:26 |
|
whartung |
OH NOES! 5 lines of code... |
| 22:26 |
|
whartung |
shudder, shiver, shake |

pdurbin2 |
sounds like @TransactionScoped is new: https://github.com/arun-gupta/javaee7-samples/blob/master/jta/transaction-scope/src/main/java/org/javaee7/jta/transaction/scope/MyBean.java |
| 22:30 |
|
whartung |
I don't see the difference between scenarios 1 and 2 |
| 22:33 |
|
* pdurbin2 |
looks at http://docs.oracle.com/javaee/7/api/javax/transaction/TransactionScoped.html |
| 22:35 |
|
pdurbin2 |
yeah, seems like JTA 1.2 is the new version: http://docs.oracle.com/javaee/7/tutorial/doc/overview008.htm |
| 22:35 |
|
whartung |
seems messy |
| 22:35 |
|
whartung |
using that stuff over EJB |
| 22:35 |
|
pdurbin2 |
they're talking JSF now... that new versions allow you to do file upload |
| 22:36 |
|
whartung |
Revolutionary! |

pdurbin2 |
whartung: imagine turbotax... you want people to back up and work on earlier parts |
| 22:42 |
|
pdurbin2 |
you want to allow them to skip around |
| 22:43 |
|
whartung |
wizard stuff |
| 22:43 |
|
pdurbin2 |
question from the audience: "Does the back button work?" :) |
| 22:43 |
|
whartung |
that's what I figured |
| 22:43 |
|
pdurbin2 |
yeah, wizard |
| 22:43 |
|
whartung |
heh yea, |

pdurbin2 |
heh |
| 22:49 |
|
pdurbin2 |
so that version was the old way. here's the newer, shorter way: https://github.com/arun-gupta/javaee7-samples/blob/master/jaxrs/jaxrs-client/src/main/java/org/javaee7/jaxrs/client/TestJAXRS2Client.java |

pdurbin2 |
whartung: it's not for you... it's for me... future me :) |
| 22:50 |
|
whartung |
no, sure, but just typing them in -- and accurately…from a slide -- bueno |
| 22:51 |
|
whartung |
you've seen me type -- I can't type my name |
| 22:53 |
|
pdurbin2 |
nope. like I said.. no slides :) "code is king" |
| 22:53 |
|
whartung |
ok |
| 22:53 |
|
whartung |
well, anything on the big screen up front is a "slide" |

whartung |
yes |
| 23:35 |
