on to Java EE 8 discussion |
| 00:04 |
|
whartung |
eager to hear what they're scheming next |
| 00:04 |
|
pdurbin |
considering ways to leverage SE 8 features |
| 00:04 |
|
whartung |
stateless lambda beans! |
| 00:04 |
|
pdurbin |
2.5 - 3 years after EE 7 |
| 00:04 |
|
pdurbin |
("our usual pace") |
| 00:05 |
|
pdurbin |
first idea: JCache |
| 00:05 |
|
whartung |
?? |
| 00:05 |
|
pdurbin |
next idea: Data Grid API (JSR 347) |
| 00:05 |
|
pdurbin |
builds on JCache |
| 00:05 |
|
pdurbin |
another: STate management API jsr 350 |
| 00:06 |
|
pdurbin |
another: identity api, jsr 351 |
| 00:06 |
|
pdurbin |
another: cloud |
| 00:06 |
|
pdurbin |
:) |
| 00:06 |
|
pdurbin |
"is cloud mature yet?" |
| 00:06 |
|
pdurbin |
"is it time to standardize yet?" |
| 00:07 |
|
pdurbin |
I'm glad to see SAML listed at http://jcp.org/en/jsr/detail?id=351 |
| 00:08 |
|
whartung |
yea, dunno why they're attacking this again |
| 00:08 |
|
pdurbin |
another idea: NoSQL |
| 00:08 |
|
whartung |
it STILL won't be used :) |
| 00:08 |
|
pdurbin |
"is it time to standardize yet?" (again) |
| 00:08 |
|
pdurbin |
"based on JPA?" |
| 00:08 |
|
pdurbin |
"new API?" |
| 00:09 |
|
whartung |
standardize what? |
| 00:09 |
|
pdurbin |
"just a simple key/value store API?" |
| 00:09 |
|
whartung |
uh..Map? |
| 00:09 |
|
pdurbin |
whartung: standardize a NoSQL API... is it time? |
| 00:09 |
|
whartung |
eh |
| 00:10 |
|
whartung |
I think there's too much variance in implementations |
| 00:10 |
|
whartung |
abstraction limits the usefulness and distinguishing properties of them all |
| 00:10 |
|
pdurbin |
another idea: more CDI |
| 00:10 |
|
pdurbin |
another idea: security interceptors |
| 00:11 |
|
pdurbin |
"apply container managed security to any bean" |
| 00:11 |
|
whartung |
yea |
| 00:11 |
|
whartung |
well that's the question |
| 00:11 |
|
pdurbin |
"port of deconstructing the EJB programming model" |
| 00:11 |
|
whartung |
are Session beans going away? |
| 00:11 |
|
whartung |
yea |
| 00:11 |
|
whartung |
exactly |
| 00:11 |
|
whartung |
are we only keep ing them for remote EJBs? |
| 00:12 |
|
pdurbin |
buh. they didn't say they're going away |
| 00:12 |
|
pdurbin |
another idea: improved security framework |
| 00:12 |
|
pdurbin |
another idea: JAX-RS MVC |
| 00:12 |
|
whartung |
I don't even know what that means |
| 00:12 |
|
pdurbin |
"action-oriented web framework" |
| 00:12 |
|
whartung |
oh please |
| 00:13 |
|
whartung |
no |
| 00:13 |
|
pdurbin |
heh |
| 00:13 |
|
pdurbin |
another idea: "more html 5, mobile alignment" |
| 00:13 |
|
pdurbin |
"write web user interface in javascript" |
| 00:13 |
|
whartung |
JAX-RS could use better binding |
| 00:13 |
|
pdurbin |
"look at project avatar" |
| 00:13 |
|
whartung |
like Struts 2 and Stripes |
| 00:13 |
|
pdurbin |
another idea: more config flexibility and control |
| 00:13 |
|
pdurbin |
another idea: templating support |
| 00:14 |
|
whartung |
we have JSPs :) |
| 00:14 |
|
pdurbin |
"templates for any web page" |
| 00:14 |
|
pdurbin |
another idea: logging improvements |
| 00:14 |
|
pdurbin |
another idea: more embedded support |
| 00:14 |
|
whartung |
that's an SE issue |
| 00:14 |
|
whartung |
logging... |
| 00:14 |
|
pdurbin |
"embedded web container, like EJB container" |
| 00:14 |
|
whartung |
JAva already has one |
| 00:14 |
|
pdurbin |
"primarily for testing?" |
| 00:14 |
|
whartung |
it's terrible |
| 00:14 |
|
whartung |
but it's there |
| 00:15 |
|
pdurbin |
[#JAVAEE_SPEC-27] Standardize Embedded Containers/Testing - Java.net JIRA - https://java.net/jira/browse/JAVAEE_SPEC-27 |
| 00:15 |
|
whartung |
yea |
| 00:15 |
|
whartung |
I mean, that would be cool I guess |
| 00:15 |
|
pdurbin |
idea: jms messages as cdi events |
| 00:15 |
|
pdurbin |
(missed the second to last one, flew by too quickly) |
| 00:15 |
|
whartung |
I haven't worked with CDI events |
| 00:16 |
|
pdurbin |
meeting tomorrow of platform expert group |
| 00:16 |
|
whartung |
I imagine they're trivial to d yourself |
| 00:16 |

| 00:16 |
|
whartung |
is today the last day or is there more tomorrow? |
| 00:16 |
|
pdurbin |
tomorrow and thursday |
| 00:16 |
|
whartung |

hi |
| 13:34 |
|
newbiee |
i'm a newbie in java |
| 13:35 |
|
newbiee |
i'm not understanding this statement String holder="sae"; |
| 13:35 |
|
Fubar^ |
it creates a string variable named holder with the value "sae" |
| 13:36 |
|
newbiee |
Fubar^: Thats where i'm getting confused |
| 13:37 |
|
Fubar^ |
where? |
| 13:37 |
|
newbiee |
Is holder is a instance variable ? |
| 13:37 |
|
newbiee |
but string class seems to have no instance variable at all |
| 13:37 |
|
newbiee |
String* |
| 13:38 |
|
Fubar^ |
there is nothing called instance variable |
| 13:38 |
|
Fubar^ |
do you understand the statement int foo = 3; |
| 13:38 |
|
newbiee |
?? |
| 13:39 |
|
newbiee |
yes i do |
| 13:39 |
|
Fubar^ |
there is no difference |
| 13:39 |
|
newbiee |
why no difference |
| 13:39 |
|
Fubar^ |
you have "type name = value;" |
| 13:39 |
|
newbiee |
It an Object oriented right |
| 13:40 |
|
Fubar^ |
what? |
| 13:41 |
|
raelianer |
you mean it's not a literal? |
| 13:41 |
|
raelianer |
it does not matter how it's been implemented, just treat it the same as int |
| 13:42 |
|
newbiee |
Wait ! .......... String must hold onto some char[] as instance variable right ? |
| 13:42 |
|
raelianer |
this is not c++ |
| 13:43 |
|
newbiee |
Java is OO right ? |
| 13:43 |
|
raelianer |
sure and don't worry about the implementation |
| 13:44 |
|
newbiee |
I'm worried where can i know how its implemented bro |
| 13:44 |
|
raelianer |
if you are a newbie, you should not worry about that |
| 13:45 |
|
raelianer |
otherwise you can educate yourself about building compilers |
| 13:45 |
|
newbiee |
please let me know |
| 13:45 |
|
raelianer |
look at the source code? |
| 13:47 |
|
newbiee |
I looked at the documentation my bad . Err how stupid i am |
| 13:47 |
|
newbiee |
/** The value is used for character storage. */ private final char value[]; cool |
| 13:48 |
|
newbiee |
Thank You raelianer |
| 13:48 |
|
raelianer |
open source ftw lol |
| 13:48 |
|
raelianer |
you're welcome |
| 13:49 |
|
newbiee |
raelianer: Bye |
| 13:49 |
|
newbiee |
Fubar^: You need to recheck on beginner java :D. |
| 13:49 |
|
raelianer |
newbiee: bye |
| 13:52 |
|
Fubar^ |
Did he think I was wrong about something? :) |
| 13:52 |
|
raelianer |
I don't know, haven't really understood him... |
| 13:53 |
|
raelianer |
guess he meant instance variables would be the objects during runtime |
| 13:53 |
|
raelianer |
oh wait, I guess private variables? |
| 13:54 |
|
raelianer |
seems to be messed up a bit |

OSGi might be fun is you start out that way, but bringing it in late to the party -- that's no fun at all. |

does anyone write to the OSGI layer? that would bypass the JEE api layer |

my understanding is container/impl suppliers write to the OSGI layer |

right, it does. GF has a hybrid model |

pdurbin |
50% of their code base is javascript |

or something |

it's IS really neat..but…kind of complicated, hard to justiry |

|
pdurbin |
say no to globals in javascript :) |
| 22:10 |
|
whartung |
yea, even the namespaces are in namespaces |
| 22:10 |
|
pdurbin |
use anonymous functions instead |
| 22:11 |

tjsnell |
I use osgi all the time |
| 22:12 |

but I wouldn't even consider a job where ejb's and crowd were in use |
| 22:12 |

pdurbin |
no to static names (namespacing) |
| 22:12 |
|
pdurbin |
don't make private methods public |
| 22:13 |
|
pdurbin |
instead, put helper function inside anonymous function |
| 22:13 |

then they wouldn't be private then, would they? |

| 22:36 |
|
pdurbin |
they minify their javascript with r.js: https://github.com/jrburke/r.js |
| 22:36 |
|
pdurbin |
per http://requirejs.org/docs/optimization.html |
| 22:38 |

pdurbin |
(under "advanced") |
| 22:42 |
|
pdurbin |
talking about shims: http://requirejs.org/docs/api.html#config-shim |
| 22:43 |
|
pdurbin |
on to angularjs (as a use case, perhaps?) |
| 22:43 |
|
pdurbin |
angular has it on module system |
| 22:43 |
|
pdurbin |
its* |
| 22:44 |
|
pdurbin |
allows you to use non-angular modules |
| 22:44 |
|
pdurbin |
using both module systems that is |
| 22:45 |
|
pdurbin |
dependency injection in angular |
| 22:45 |
|
pdurbin |
i.e. injecting a "basket" service |

hmm, this might be the code he's showing: https://bitbucket.org/amdatu/showcase/src |
| 22:51 |
|
pdurbin |
yeah, this I think: https://bitbucket.org/amdatu/showcase/src/1e078853256ef1088295f9d3df246ce8b113d8aa/webshop.frontend.ui/static/js/webshop.services.js?at=master |

pdurbin |
"what about the future" |
| 22:55 |
|
pdurbin |
ES6 basically |
| 22:55 |

next session: Application Resilience Engineering and Operations at Netflix with Hystrix [CON2624] https://oracleus.activeevents.com/2013/connect/sessionDetail.ww?SESSION_ID=2624 |
| 23:12 |
|
pdurbin |
with https://twitter.com/benjchristensen |
| 23:14 |
|
pdurbin |
hmm, I wonder if this will be his talk, more or less: http://benjchristensen.com/2013/06/10/application-resilience-in-a-service-oriented-architecture-using-hystrix/ |
| 23:15 |

"Hystrix is a latency and fault tolerance library designed to isolate points of access to remote systems, services and 3rd party libraries, stop cascading failure and enable resilience in complex distributed systems where failure is inevitable." -- https://github.com/Netflix/Hystrix |

|
pdurbin |
wow, tons of docs: https://github.com/Netflix/Hystrix/wiki/How-To-Use |
| 23:29 |
|
pdurbin |
ok, talk underway |
| 23:29 |
|
pdurbin |
service oriented architecture |
| 23:29 |
|
pdurbin |
two major edge services: discovery and streaming |
| 23:29 |
|
pdurbin |
he's talking about discovery |
| 23:32 |
|
pdurbin |
"machine failure is a solved problem in our infrastructure" |
| 23:32 |
|
pdurbin |
(chaos monkey) |
| 23:32 |
|
pdurbin |
instead, he's talking about failure within the application |
| 23:32 |
|
pdurbin |
showing a slide that looks something like https://raw.github.com/wiki/Netflix/Hystrix/images/soa-1-640.png |
| 23:33 |
|
pdurbin |
user request blocked by latency |
| 23:33 |
|
pdurbin |
at high volume, all request threads can block in seconds |
| 23:33 |
|
pdurbin |
tomcat |
| 23:35 |
|
pdurbin |
focus on speed of iteration |
| 23:35 |
|
whartung |
iteration of what? |
| 23:35 |
|
pdurbin |
development |
| 23:35 |
|
pdurbin |
he's talking about constraints |
| 23:35 |
|
pdurbin |
in developing their solution |
| 23:36 |
|
pdurbin |
teams delivery client libraries |
| 23:36 |
|
pdurbin |
deliver* |
| 23:36 |
|
pdurbin |
systems do get coupled together, but they accept that |
| 23:37 |
|
pdurbin |
last constraint: account for groovy, scala, clojure, and java (mixed environment) |
| 23:38 |
|
pdurbin |
back in the day, failure of one system would bring down all of netflix |
| 23:39 |

Tryable Semaphore |
| 23:41 |
|
whartung |
uh…aren't they all? |
| 23:41 |
|
pdurbin |
:) |
| 23:41 |
|
pdurbin |
one step back... Thread-pool |
| 23:42 |
|
pdurbin |
has timeouts |
| 23:43 |
|
pdurbin |
"in those cases we choose to use tryable semaphores which do not allow for timeouts but provide most of the resilience benefits without the overhead" -- https://github.com/Netflix/Hystrix/wiki/FAQ |
| 23:44 |
|
pdurbin |
4 tools |
| 23:44 |
|
pdurbin |
- tryable semaphores |
| 23:44 |
|
pdurbin |
- separate threads |
| 23:44 |
|
pdurbin |
- aggressive timeouts |
| 23:44 |
|
pdurbin |
- circuit breakers |

"don't think putting stuff into a queue is free" |
| 23:50 |
|
pdurbin |
they are anti-queue, generally speaking |
| 23:50 |
|
tjsnell |
anti queue makes no sense |
| 23:51 |

may migrate from tomcat to netty for the front end |
| 23:54 |
|
pdurbin |
hoping to be full non-blocking on the front end in 6 months |
