Making Java more dynamic: runtime code generation for the JVM
While Java’s strict type system is a great help for avoiding programming errors, it also takes away some of the flexibility that developers appreciate when using dynamic languages. By using runtime code generation, it is possible to bring some of this flexibility back to the Java virtual machine. For this reason, runtime code generation is widely used by many state-of-the-art Java frameworks for implementing POJO-centric APIs but it also opens the door to assembling more modular applications. This presentation offers an introduction to the complex of runtime code generation and its use on the Java platform. Furthermore, it discusses the up- and downsides of several code generation libraries such as ASM, Javassist, cglib and Byte Buddy.
Java is an object-oriented programming language created by James Gosling. It was originally called Oak but was later renamed to Java. The document discusses the different editions of Java including J2SE, J2EE, and J2ME. It also covers key Java technologies like applets, servlets, JSP, and Swing. The document provides an overview of Java features such as being platform independent, portable, multi-threaded, and having a Java Virtual Machine. It also discusses concepts like inheritance, interfaces, packages, exceptions, and input/output in Java.
Writing software for a virtual machine enables developers to forget about machine code assembly, interrupts, and processor caches. This makes Java a convenient language, but all too many developers see the JVM as a black box and are often unsure of how to optimize their code for performance. This unfortunately adds credence to the myth that Java is always outperformed by native languages. This session takes a peek at the inner workings of Oracle’s HotSpot virtual machine, its just-in-time compiler, and the interplay with a computer’s hardware. From this, you will understand the more common optimizations a virtual machine applies, to be better equipped to improve and reason about a Java program’s performance and how to correctly measure runtime!
Understanding Java byte code and the class file format
At first glance, Java byte code can appear to be some low level magic that is both hard to understand and effectively irrelevant to application developers. However, neither is true. With only little practice, Java byte code becomes easy to read and can give true insights into the functioning of a Java program. In this talk, we will cast light on compiled Java code and its interplay with the Java virtual machine. In the process, we will look into the evolution of byte code over the recent major releases with features such as dynamic method invocation which is the basis to Java 8 lambda expressions. Finally, we will learn about tools for the run time generation of Java classes and how these tools are used to build modern frameworks and libraries. Among those tools, I present Byte Buddy, an open source tool of my own efforts and an attempt to considerably simplify run time code generation in Java. (http://bytebuddy.net)
This document discusses Java bytecode manipulation techniques using unsafe, instrumentation, and Java agents. It covers areas where bytecode manipulation is commonly used like mocking, persistence, and security. It analyzes techniques for defining and transforming classes at runtime and discusses challenges like injecting state and working with modules. The document also proposes ideas to standardize testing support and provide a unified dynamic code generation concept in Java.

Object Oriented Programming (OOP) allows developers to organize complex programs using classes and objects. OOP uses concepts like encapsulation, inheritance and polymorphism to keep data and functionality together in objects. The basic building blocks in OOP are classes, which define the properties and methods of an object, and objects, which are instances of classes. Classes can inherit properties and methods from parent classes, and objects can be identified and compared using operators like instanceof. Magic methods allow objects to override default behavior for operations like property access, method calling and object destruction.
Java allows writing code once that can run on any platform. It compiles to bytecode that runs on the Java Virtual Machine (JVM). Key features include automatic memory management, object-oriented design, platform independence, security, and multi-threading. Classes are defined in .java files and compiled to .class files. The JVM interprets bytecode and uses just-in-time compilation to improve performance.
This document provides an overview of the Java programming language.

While most bugs reveal their cause within their stack trace, Java’s OutOfMemoryError is less talkative and therefore regarded as being difficult to debug by a majority of developers. With the right techniques and tools, memory leaks in Java programs can however be tackled like any other programming error. This talks discusses how a JVM stores data, categorizes different types of memory leaks that can occur in a Java program and presents techniques for fixing such errors. Furthermore, we will have a closer look at lambda expressions and their considerable potential of introducing memory leaks when they are used incautiously.
At first glance, Java byte code can appear to be some low level magic that is both hard to understand and effectively irrelevant to application developers. However, neither is true.

Quality Patents: Patents That Stand the Test of TimeAurora Consulting
Is your patent a vanity piece of paper for your office wall? Or is it a reliable, defendable, assertable, property right? The difference is often quality.
Is your patent simply a transactional cost and a large pile of legal bills for your startup? Or is it a leverageable asset worthy of attracting precious investment dollars, worth its cost in multiples of valuation? The difference is often quality.
Is your patent application only good enough to get through the examination process? Or has it been crafted to stand the tests of time and varied audiences if you later need to assert that document against an infringer, find yourself litigating with it in an Article 3 Court at the hands of a judge and jury, God forbid, end up having to defend its validity at the PTAB, or even needing to use it to block pirated imports at the International Trade Commission? The difference is often quality.
Quality will be our focus for a good chunk of the remainder of this season. What goes into a quality patent, and where possible, how do you get it without breaking the bank?
** Episode Overview **
In this first episode of our quality series, Kristen Hansen and the panel discuss:
⦿ What do we mean when we say patent quality?
⦿ Why is patent quality important?
⦿ How to balance quality and budget
⦿ The importance of searching, continuations, and draftsperson domain expertise
⦿ Very practical tips, tricks, examples, and Kristen’s Musts for drafting quality applications

Coordinate Systems in FME 101 - Webinar SlidesSafe Software
If you’ve ever had to analyze a map or GPS data, chances are you’ve encountered and even worked with coordinate systems. As historical data continually updates through GPS, understanding coordinate systems is increasingly crucial. However, not everyone knows why they exist or how to effectively use them for data-driven insights.
During this webinar, you’ll learn exactly what coordinate systems are and how you can use FME to maintain and transform your data’s coordinate systems in an easy-to-digest way, accurately representing the geographical space that it exists within. During this webinar, you will have the chance to:
- Enhance Your Understanding: Gain a clear overview of what coordinate systems are and their value
- Learn Practical Applications: Why we need datams and projections, plus units between coordinate systems
- Maximize with FME: Understand how FME handles coordinate systems, including a brief summary of the 3 main reprojectors
- Custom Coordinate Systems: Learn how to work with FME and coordinate systems beyond what is natively supported
- Look Ahead: Gain insights into where FME is headed with coordinate systems in the future
Don’t miss the opportunity to improve the value you receive from your coordinate system data, ultimately allowing you to streamline your data analysis and maximize your time. See you there!
Are you interested in dipping your toes in the cloud native observability waters, but as an engineer you are not sure where to get started with tracing problems through your microservices and application landscapes on Kubernetes? Then this is the session for you, where we take you on your first steps in an active open-source project that offers a buffet of languages, challenges, and opportunities for getting started with telemetry data.
The project is called openTelemetry, but before diving into the specifics, we’ll start with de-mystifying key concepts and terms such as observability, telemetry, instrumentation, cardinality, percentile to lay a foundation. After understanding the nuts and bolts of observability and distributed traces, we’ll explore the openTelemetry community; its Special Interest Groups (SIGs), repositories, and how to become not only an end-user, but possibly a contributor.We will wrap up with an overview of the components in this project, such as the Collector, the OpenTelemetry protocol (OTLP), its APIs, and its SDKs.
Attendees will leave with an understanding of key observability concepts, become grounded in distributed tracing terminology, be aware of the components of openTelemetry, and know how to take their first steps to an open-source contribution!
Key Takeaways: Open source, vendor neutral instrumentation is an exciting new reality as the industry standardizes on openTelemetry for observability. OpenTelemetry is on a mission to enable effective observability by making high-quality, portable telemetry ubiquitous. The world of observability and monitoring today has a steep learning curve and in order to achieve ubiquity, the project would benefit from growing our contributor community.

Mitigating the Impact of State Management in Cloud Stream Processing SystemsScyllaDB
Stream processing is a crucial component of modern data infrastructure, but constructing an efficient and scalable stream processing system can be challenging. Decoupling compute and storage architecture has emerged as an effective solution to these challenges, but it can introduce high latency issues, especially when dealing with complex continuous queries that necessitate managing extra-large internal states.
In this talk, we focus on addressing the high latency issues associated with S3 storage in stream processing systems that employ a decoupled compute and storage architecture. We delve into the root causes of latency in this context and explore various techniques to minimize the impact of S3 latency on stream processing performance. Our proposed approach is to implement a tiered storage mechanism that leverages a blend of high-performance and low-cost storage tiers to reduce data movement between the compute and storage layers while maintaining efficient processing.
Throughout the talk, we will present experimental results that demonstrate the effectiveness of our approach in mitigating the impact of S3 latency on stream processing. By the end of the talk, attendees will have gained insights into how to optimize their stream processing systems for reduced latency and improved cost-efficiency.

Learning Java 1 – Introduction
1. Learning Java 1: Introduction Christopher Swenson Center for Information Security University of Tulsa 600 S. College Ave Tulsa, OK 74104
2. Learning Java Based on Learning Java , by Niemeyer and Knudsen Quick and Dirty overview of Java fundamentals and advanced programming Introduction Objects and Classes Generics, Core Utilities Threads, Synchronization I/O, Network Programming Swing
4. Java Modern, Object-Oriented (OO) Language with C-like syntax Developed at Sun Microsystems (James Gosling, Bill Joy) in the early 1990s Virtual Machine Intermediate bytecode Extremely portable Surprisingly fast (comparable to C++) Features HotSpot on-the-fly native compiling Safe and Clean Dynamic Memory Management Robust Error Handling http://java.sun.com http://java.sun.com/j2se/1.5.0/docs/api/
5. Let’s Go! Standard CLI utilities, although IDEs and GUIs exist (Eclipse, Netbeans) Windows: Start Run “ cmd ” UNIX / OS X: Open up a command terminal “ javac HelloJava.java ” Compiles the file HelloJava.java Outputs executable .class files
6. HelloJava.java public class HelloJava { public static void main(String[] args) { System.out.println(“Hello World!”); } } Run with: java -cp . HelloJava Outputs: Hello World!
7. Some Notes public class HelloJava { … Everything in Java must be in a class (container for code and data). public static void main(String[] args){ … This is a method (which contains executable code). The function called from the command-line is required to be main . Takes a String array (the arguments), and returns nothing ( void ). System.out.println(“Hello World!”); System is a class that contains a lot of useful system-wide tools, like standard I/O, and its out class represents standard out. The println method of out (and all PrintStream objects) prints the String containted within, followed by a newline. java -cp . HelloJava Invokes the Java Virtual Machine (JVM) to execute the main of the named class ( HelloJava ). Searches the current directory for the class file ( -cp . ).
8. Comments /* */ C-style comments are also supported /** */ are special JavaDoc comments Allow automatic documentation to be built from source code, using the javadoc utility. // C++-style comments are preferred Less ambiguity Simpler
9. Variables String s = “string”; int a = -14; long b = 5000000000l; float c = 2.5f; double d = -4.0d; byte e = 0x7f; char f = ‘c’; short g = -31000; boolean h = true; int s are signed 32-bit long s are signed 64-bit float s are signed 32-bit double s are signed 64-bit byte s are signed 8-bit char s are signed 16-bit short s are signed 16-bit boolean s are 1-bit, either true or false
10. Operators Standard arithmetic operators for ints, longs, shorts, bytes, floats and doubles + - * / % << >> >>> Boolean operators for non-floating point & | ^ ~ Logical operators for boolean s && || ^^ ~ Comparisons generate boolean s == < <= > >= != Can be suffixed with = to indicate an assignment a = a + b a += b ++ and -- operators also ( a = a - 1 a-- ) Ternary Operator: (a >= b) ? c : d if (a >= b) c else d
11. Reference Types Reference Types are non-primitive constructs Includes String s Consist of variables and methods (code) Typically identified with capital letter Foo bar = new Foo(); Use the new keyword to explicitly construct new objects Can take arguments No need for destructor or to explicitly remove it No pointers C++: Foo &bar = *(new Foo());
12. String Strings are a reference type, but almost a primitive in Java String s = “this is a string”; No need for new construction Overloaded + operator for concatenation String s = “a” + “ kitten”;
13. Coercion Coercion = automatic conversion between types Up is easy ( int to double , anything to String ) Down is hard int i = 2; double num = 3.14 * i; String s = “” + num; int a = Integer.parseInt(t);
14. Expressions and Statements An statement is a line of code to be evaluated a = b; An statement can be made compound using curly braces { a = b; c = d; } Curly braces also indicate a new scope (so can have its own local variables) Assignments can also be used as expressions (the value is the value of the variable after the assignment) a = (b = c);
15. if-then-else statements if (bool) stmt1; if (bool) stmt1 else statement2; if (bool) stmt1 else if stmt2 else stmt3; if (bool) { stmt1; … ; } … if (i == 100) System.out.println(i);
16. Do-while loops while (bool) stmt; do stmt; while (bool); boolean stop = false; while (!stop) { // Stuff if (i == 100) stop = true; }
17. for loops for ( prestmt ; bool ; stepstmt ;) stmt ; = { prestmt ; while ( bool ) { stmt ; stepstmt ; } } for (int i = 0; i < 10; i++) { System.out.print(i + “ “); } Outputs: “ 0 1 2 3 4 5 6 7 8 9 ”
18. switch statement switch ( int expression ) { case int_constant : stmt ; break ; case int_constant : stmt ; case int_constant : stmt ; default: stmt ; }
19. Arrays int [] array = { 1,2,3 } ; int [] array = new int[ 10 ]; for (int i = 0; i < array.length ; i++) array [ i ] = i; Array indices are from 0 to (length – 1) Multi-dimensional arrays are actually arrays of arrays: int [][] matrix = new int [3][3]; for (int i = 0; i < matrix.length ; i++) for (int j = 0; j < matrix[i].length ; j++) System.out.println(“Row: “ + i + “, Col: “ + j + “ = “ + matrix [i][j] );
20. enum s What about something, like size? Pre-Java 1.5, int small = 1, medium = 2, … But what if mySize == -14 ? enum Size {Small, Medium, Large}; Can also do switch statements on enums switch (mySize) { case Small: // … default: // … }
21. Loop breaking break breaks out of the current loop or switch statement while (!stop) { while (0 == 0) { break ; } // Execution continues here }
22. Loop continuing continue goes back to the beginning of a loop boolean stop = false; int num = 0; while (!stop) { if (num < 100) continue ; if (num % 3) stop = true; }
23. Objects class Person { String name; int age; } Person me = new Person(); me.name = “Bill”; me.age = 34; Person[] students = new Person[50]; students[0] = new Person();
24. Subclassing class Professor extends Person { String office; } Professor bob = new Professor(); bob.name = “Bob”; bob.age = 40; bob.office = “U367”; However, a class can only “extend” one other class
25. Abstract Classes If not all of its methods are implemented (left abstract), a class is called abstract abstract class Fish { abstract void doesItEat(String food); public void swim() { // code for swimming } }
26. Interfaces class MyEvent implements ActionListener { public void actionPerformed(ActionEvent ae) { System.out.println(“My Action”); } } Can implement multiple interfaces Interfaces have abstract methods, but no normal variables
27. Static and final A static method or variable is tied to the class, NOT an instance of the class Something marked final cannot be overwritten (classes marked final cannot be subclassed) class Person { public final static int version = 2; static long numberOfPeople = 6000000000; static void birth() { numberOfPeople++; } String name; int age; } // … in some other code Person.numberOfPeople++; System.out.println(“Running Version “ + Person.version + “ of Person class);
28. Special functions All classes extend the Object class Classes have built-in functions: equals(Object obj), hashCode(), toString() Equals used to determine if two objects are the same o == p – checks their memory addresses o.equals(p) – runs o.equals() hashCode() – used for hash tables ( int ) toString() – used when cast as a String (like printing)
29. Packages Classes can be arranged into packages and subpackages, a hierarchy that Java uses to find class files Prevents naming issues Allows access control By default, a null package Doesn’t work well if you need more than a few classes, or other classes from other packages java.io – Base I/O Package java.io.OutputStream – full name Declare a package with a package keyword at the top Import stuff from package with the import keyword import java.io.*; import java.util.Vector; import static java.util.Arrays.sort;
30. Using Packages Compile like normal Packages = a directory Java has a “classpath”: root directories and archives where it expects to look for classes Example java -cp compiled swenson.MyServer In the the “compiled” directory, look for a class MyServer in the subfolder “swenson” /compiled/swenson/MyServer.class Also need to specify -classpath when compiling Class files can also be put into ZIP files (with a suffix of JAR instead of ZIP)
31. Permissions public – accessible by anyone protected – accessible by anything in the package, or by subclasses (default) – accessible by anything in the package private – accessible only by class
32. Coding Style class Test { public static void main(String[] args) { if (args.length > 0) System.out.println(“We have args!”); for (int i = 0; i < args.length; i++) { int q = Integer.parseInt(args[i]); System.out.println(2 * q); } System.exit(0); } }
39. Homework Download Java Download a GUI and learn it (e.g., Eclipse) Implement a Card class enum s for Suit hashCode() should return a different value for two different cards, but should be the same for two instances of the same card (e.g., Jack of Diamonds) Write a program that builds a deck and deals 5 cards to 4 different players toString() should work so you can use System.out.println() to print out a deck, hand, or a card
