@richardstartin @snatverk @netflix @forked_franz ... the jira issue before I had a JVM solution worked out. Still working that out. BTW, I don't have to be the one that fixes the issue - I just want it fixed!
@richardstartin @snatverk @netflix @forked_franz Yes, both groups have been working on this independently for months. Both are excellent examples of performance analysis, and both blog/video postings cover some common ground but highlight complementary technical issues. Seeing @forked_franz's new case pushed me to re-raise...
@christophdreis @brendangregg More cores, more problems😀. Seriously, this was an under-appreciated problem when it was first brought up. And if you squint enough, it's not that different from bugs.openjdk.org/browse/JDK-827…. Knowing one doesn't help you find another, but there's a set of solutions...
@carter_kozak @brendangregg @forked_franz Yes, I think so. Both cases are referenced in OpenJDK issue bugs.openjdk.org/browse/JDK-818… targeting this issue. There are a few solutions to the problem in progress (that DON'T involve avoiding basic language features like instanceof and checkcast!)
@BrianGoetz @HomeDepot You didn’t say what kind of garbage disposal you chose - a Concurrent disposal runs intermittently, but never for very long. Parallel can dispose of your whole sink in one go. Or a Cereal garbage disposal? I can never find a good use for those.
Intel's JPE group has been a long-standing contributor to the #OpenJDK project. Now hiring! Looking for people excited to work on Java performance and implementation all the way from micro-services to micro-architecture. linkedin.com/jobs/view/2766…
My Open Letter to the Open Ecosystem 👇 Highlights:
@davidgsIoT 3/3 The only reason nobody definitely died is the thin wire acted as a safety fuse. Did it work? Count the number of times I used the words "calculated, math, or adult supervision" :-) (the '70s). Sweet pecan stain on the control box though.
@davidgsIoT 2/3 - Place wire screen on either end of kite - Connect to rectified 120V DC - Place high voltage spark gap in center of kite to "ionize air" - Connect to Control Box with thinnest possible wire (28+ guage?)
@mreinhold It's great to see Oracle providing AArch64 binaries again! Joining AdoptOpenJDK, Amazon, Azul, and Bellsoft as well as major linux distros. #Java + #Arm64
@chegar999 24 years ago I had my first kid, and started working on Java. I've been working off and on Java (and the kids) ever since. This weekend marks the commencement of a new phase. #MovedbyJava / #MadebyJava. Thanks Java - I'll get back to you next week!
