From Java Code to Java Heap: Understanding the Memory Usage of Your Application
 
56:47
When you write and run Java code, the JVM makes several allocations on your behalf, but do you have an understanding of how much that is? This session provides insight into the memory usage of Java code, covering the memory overhead of putting "int" into an integer object and the cost of object delegation and the memory efficiency of the different collection types. It also gives you an understanding of the off-Java (native) heap memory usage of some types of Java objects, such as threads and sockets. Most importantly, the session covers how to determine where there are inefficiencies in your application and how to choose the right collections to improve your Java code.

A Deep Dive into Java Performance Analysis with Advanced Toolsets
 
46:32
"Tackling performance issues on modern hardware has become a complex activity due to new multicore topologies, varieties of cache systems, and advanced microarchitecture optimizations. The choice of a proper tool can be a key to resolving critical bottlenecks. Some of the issues can be identified only with specialized tools such as those that have access to processor events. This session gives an overview of existing performance analysis tools for Java and highlights the enhanced analysis capabilities of two advanced toolsets: Oracle Solaris Performance Analyzer and Intel VTune Amplifier XE. It covers features of each, shares analysis methodologies that use these toolsets, and provides real case examples based on the speakers' experience." Copyright © 2013 Oracle and/or its affiliates.

JVM Bytecode for Dummies (and the Rest of Us Too)
 
50:34
You've written applications for the JVM, using various frameworks and maybe even various languages. You understand how to rig up the CLASSPATH, get .class files to load, compile source, and set up an IDE. But you've always wanted a better understanding of the plumbing underneath. How does JVM bytecode work? How does the JVM itself work? This presentation walks you through JVM and JVM bytecode basics, with lots of examples of how to bend the JVM to your whims.

Java Thread Dump Analysis, Thread Dump: Thread Stack Trace analysis, A thread dump can only show the thread status at the time of measurement, so in order to see the change in thread status, it is recommended to extract them from 5 to 10 times with 5-second intervals. The thread dump is written to the system out of the VM on which you executed the kill -3. If you are redirecting the console output of the JVM to a file, the thread dump will be in that file. If the JVM is running in an open console, then the thread dump will be displayed in its console. java thread dump jstack tutorial Using kill -QUIT to trigger Thread dump without restarting the Server Java Thread Activity Analyzer kill -3 to get java thread dump Java Análisis de Problemas Thread, Dump Tema: Análisis de trazas de pila del subproceso, Un volcado de hilo sólo puede mostrar el estado de hilo en el momento de la medición, por lo que con el fin de ver el cambio en el estado de hilo, se recomienda extraerlas de 5 a 10 veces con intervalos de 5 segundos.

Big O Notations
 
20:31
Get the Code Here: http://goo.gl/Y3UTH Welcome to my Big O Notations tutorial. Big O notations are used to measure how well a computer algorithm scales as the amount of data involved increases. It isn't however always a measure of speed as you'll see. This is a rough overview of Big O and I hope to simplify it rather than get into all of the complexity. I'll specifically cover the following O(1), O(N), O(N^2), O(log N) and O(N log N). Between the video and code below I hope everything is completely understandable.

"Introduction into Java Profiling" by Fabian Lange - Coding Serbia Conference
 
43:46
As developers, we sometimes need to improve the performance our code. Or worse: the code in third party libraries. This talk gives a little bit of background information on why code can be slow, what free and commercial tools we have at hand to measure it, and how different measuring techniques differ. We then apply what we learned by troubleshooting a real performance issue in a real application. The second part of the talk covers the problems associated to high memory allocation and memory leaks, which, unlike unicorns do exist in Java, and will also present a real world application exhibiting these problems, which we will fix. After attending the talk, you will be able to resolve time and memory problems in your applications more easily.

Improve Your Java Code, Functional-Style—Now!
 
52:42
Functional programming is all the rage. It can undoubtedly produce cleaner and more expressive code, but why switch to Scala or wait for Java 8? In fact, there are many ways to dramatically improve your Java code quality by using a more functional style today. This presentation discusses how techniques such as functional programming, using fluent APIs, and other clean coding practices can make your code more concise, more readable, and much easier to maintain. But more importantly, you will learn about libraries such as LambdaJ and Google Guava that make this possible today with your existing Java code base. Copyright © 2013 Oracle and/or its affiliates.

JOverflow: Advanced Heap Analysis in Java Mission Control
 
58:26
Large Java applications tend to be memory-hungry. Most profiling tools tell users which data structures consume memory but don't tell whether that's good or bad or how to improve the situation. JOverflow, a recent extension to Java Mission Control, analyzes a heap dump automatically, looking for known bad memory usage patterns. It detects empty and underused collections, duplicated strings, unused data fields, and several other issues. What's more, for many of these problems, the tool can suggest a fix by analyzing application code together with the heap dump and thus save the developer hours of tedious and unrewarding work.

Troubleshooting Live Java Web Applications
 
01:03:12
Recorded live at SpringOne2GX 2013 in Santa Clara, CA. Speaker: Ashley Puls, NewRelic Operations teams tend to get nervous when debugging tools are installed on production systems. This is understandable as most people have had at least one debugging tool crash a system. However, are there tools that can be run in a production environment? This talk will cover methods and tools that can be used to uncover and resolve performance problems arising in Java web applications that use the Spring Framework. This talk will touch on a few common problems such as slow SQL, slow web page load times, blocked threads, and exceptions in the code. It will use a variety of diagnostic tools to examine these problems including log files, jmap, jvisualvm, and New Relic. Finally, the talk will evaluate the use of these tools in a production environment, separating them into what can and cannot be realistically used in live production web applications

This is a project I put together for my Management Information Systems class this semester at Iowa State University. Wrote a java program that checks for new news articles and then used Rapidminer to do a simple keyword analysis of the downloaded articles. Things I forgot to mention in this video (I'm sure there's more): 1. The website the java program is downloading the rss articles is called fulltextrssfeed.com 2. I forgot I made some changes to one of the article methods. That's why you only 3 articles in the "new" folder. I swear works now though... 3. I understand that there are more efficient ways to write the java program. I just went with the simplest/most visual route for faster development.

JVM JIT for Dummies
 
01:01:10
Most Java developers never get past -Xmx, -classpath, and -jar when learning about the flags that JVMs offer. If you're an OpenJDK user, you know -server and -client too. But if you're a performance nut, you crave more. This session walks through several lower-level OpenJDK flags you can use to monitor what code the JVM compiles into native code, what decisions it makes along the way, and even what that native assembly looks like. You'll learn how JVM bytecode makes its way through Oracle's HotSpot and how you can write code that JVMs will optimize well. Copyright © 2013 Oracle and/or its affiliates.
