16:07 IoannisM Hi Simon
16:07 sjmaple if you have questions, throw them in here and I'll ask gleb :)
16:07 Michael_Willer :-)
16:07 sjmaple hey IoannisM
16:07 sandor_nemeth @sjmaple hey :)
16:08 sjmaple welcome sandor_nemeth :)
16:08 D-Spair Hmmm . . . Fibers, I assume he's referring to using Quasar?
16:09 NITS audio isn't great
16:09 D-Spair http://docs.paralleluniverse.co/quasar/
16:10 D-Spair NITS:  Audio is fine for me.
16:10 IoannisM same here
16:11 sjmaple maybe try a refresh NITS
16:11 sjmaple or increase your quality on the video by clicking the cog bottom right
16:11 IoannisM also change Quality from Auto to 720p
16:11 IoannisM if your connection can handle it :)
16:12 sjmaple yeh, I'd love to set that as the default on the site, but I don't think I can :(
16:12 nabil joined #virtualJUG
16:12 sandor_nemeth on youtube I automatically have 720p
16:12 Tushar screen is not clear
16:12 Tushar its blurr
16:13 gyro please more on fibers
16:13 IoannisM change quality to 720p ppl
16:13 IoannisM and all will be revealed :)
16:13 NITS that worked, thanks
16:13 Tushar thnks
16:13 avaj yes
16:13 sjmaple cool! thanks IoannisM :)
16:13 sandor_nemeth @IoannisM :)
16:14 sjmaple for those who want to hear more about the JMM session, check out this session after Gleb has finished http://virtualjug.com/java-memory-model-pragmatics/
16:14 zk joined #virtualJUG
16:14 sjmaple It's a hardcore, but really great session on JMM
16:15 Ely joined #virtualJUG
16:15 HarmeetSingh its great @simon
16:15 sjmaple by Aleksey Shipilev who Gleb has referenced a couple of times now
16:15 sjmaple yeh, although tough to follow :)
16:16 satya111 display is blurred
16:16 richm joined #virtualJUG

16:31 sjmaple select the highest quality you can
16:32 sjmaple 720p preferably
16:32 Guest52863 it helped

16:33 gyro joined #virtualJUG
16:34 jeremy_prime joined #virtualJUG
16:36 AmaliaH joined #virtualJUG
16:36 sjmaple any questions so far?
16:37 sjmaple other than video quality? ;)
16:37 marius_filip I was a little bit late. Was the @Actor annotation taken from Akka?
16:38 MarsYang joined #virtualJUG
16:39 crew4ok a question regarding jcstress: i heard that it's kind of internal openjdk project, can it be used as a standalone harness, like jmh?
16:42 millrossjez joined #virtualJUG
16:42 yshthdn joined #virtualJUG
16:43 Carl_Jokl Is there a lot of variation of handling of concurrency between x86 and ARM?
16:43 millrossjez joined #virtualJUG
16:45 Carl_Jokl I am likely to be dealing with a lot of JVM implementations on ARM
16:45 sjmaple thanks for the questions marius_filip, crew4ok and Carl_Jokl!
16:45 Carl_Jokl Sorry I missed the last meetup
16:45 Carl_Jokl I have just moved and started a new contract
16:45 Carl_Jokl Between the two I was insanely busy
16:45 sjmaple ahh, congrats :)
16:46 Carl_Jokl I will watch the recording though
16:46 sjmaple ARM related I presume :)
16:46 Carl_Jokl No that is related to my JCP membership
16:46 gyro very simple chart
16:46 Carl_Jokl I will now represent the LJC for mobile and embedded technology
16:47 Carl_Jokl I am manly motivated that I want to be a Rockstar like you obvously
16:47 Carl_Jokl mainly*
16:47 sjmaple hehe
16:47 sjmaple I should talk with you about JRebel for Android then, maybe ;(
16:47 sjmaple ;)
16:47 Carl_Jokl I expect to be delving into a lot of JVM on embedded and mobile devices
16:48 jeremy_prime joined #virtualJUG
16:48 Carl_Jokl Let me clear that with my boss...
16:48 Carl_Jokl Oh wait I am my boss...
16:48 sjmaple haha
16:49 Carl_Jokl I will probably do the JClarity advanced JVM internals course too
16:49 Carl_Jokl I can't having you running around like a champion stealing all of my attention
16:49 Carl_Jokl I am afraid that won't do
16:49 sjmaple :)
16:49 Jayho How does this relate to interpreted mode? (non-JIT compiled)
16:50 Jayho (last slide)
16:50 sjmaple Jayho: I'll ask after this demo :)
16:51 Carl_Jokl I also hope to see if I can flagrantly promote myself as an LJC associate candidate
16:51 Carl_Jokl The LJC needs me. I can prove this.
16:56 sjmaple :D
16:57 Jayho thanks :)

17:02 jeremy_p_ joined #virtualJUG
17:06 sjmaple any other final questions before we wrap up?
17:07 Carl_Jokl Where can we find more information on this topic?
17:07 Carl_Jokl Recommended books or articles?
17:08 solimo yea, especially with "every day" use cases
17:10 Carl_Jokl Now that I have a new place and my broadband is up and running I will start setting up Open Wonderland servers.
17:10 Gyro How this knowledge can be applied in `every day ` java
17:11 Carl_Jokl @sjmaple that will give me a chance to actually demonstrate Open Wonderland rather than just keep talking about it with you
17:13 itgeek left #virtualJUG
17:17 geoL I think "The Art of Multiprocessor Programming" is still good for explaining concurrency in java and underneath and how to control it(before Java 8)
17:18 avaj I agree, @geoL!
17:18 avaj One question -- how do they test this stuff?
17:19 AmaliaH Java Concurrency in Practice (Brian Goetz) is also a good book
17:20 solimo it is indeed but recently i've noticed a great shift into scaling instead of tweaking perf., so while the topic is fascinating I'd appreciate up to date use case blog/book/talk.
17:20 solimo here we go - links ;)
17:21 geoL i think by a deadlock, it was among the first examples of the book, the motivation for volatile
17:21 avaj Awesome, thank you!
17:21 Gyro Hardcore, but i liked it, thankx
17:22 Carl_Jokl I think I have concurrency in practice on Kindle
17:24 sjmaple Thanks for attending everyone, and thanks Gleb for a great session! Here's the replay -> http://virtualjug.com/java-concurrency-under-the-hood/
17:25 Jayho ok great, thanks!
17:26 solimo thx
17:26 irare Thx Gleb! It was a great talk!
17:26 Jayho good stuff
