Therefore this session tries to compare COBOL/PLI/Assembler with Java and how the Java technology works on System z: > Why can't you phase in a Java Program > How is a JIT working > Understand the Development Process of Java Applications > Debugging and Logging of Java Applications > and a lot more...
With the official release of Java EE 6 in December 2009 a new version of the Enterprise JavaBeans specification also saw the light. Enterprise JavaBeans is an architecture for the development and deployment of component-based business applications. Applications written using the Enterprise JavaBeans architecture are scalable, transactional, and concurrent.
While a lot of faithful EJB developer's have been scared away from the specification and some of its unfortunate implementations in the past five years, EJB 3.1 has all the ingredients that make for a successful lightweight component based implementation. At last a decent implementation of a server-side component framework as part of the Java EE specification. This no longer makes you dependent on rebel frameworks such as the Spring framework.
EJB 3.1 continues down the path where EJB 3.0 left us off. The purpose of the Enterprise JavaBeans 3.1 specification is to further simplify the EJB architecture by reducing its complexity from the developer's point of view, while also adding new functionality in response to the needs of the community. Although the Java Persistence API was developed within EJB 3.0, it now evolves under a separate JSR rather than within EJB 3.1 and will therefore not be covered in this presentation.
This presentation will mainly focus on the new features introduced by EJB 3.1 and the basics of EJB are only covered very briefly. Topics covered include: EJB Lite, simple packaging, no-interface local view, portable JNDI names, Embeddable API, Startup/shutdown callbacks, Singleton beans, the new and improved timer and scheduler component, Async invocations, and REST integration.

Moving From Small Science To Big Scienceguest2426e1d
The document discusses two case studies of scientific research projects - one tracking marine mammals over 40 years, and the other studying genetic factors in bipolar disorder over 20 years. Both projects grew significantly in size and scope over time. This led to challenges in organizing and managing the large amounts of data collected in a way that was compatible, standardized, and accessible to collaborators. The researchers received training in conducting scientific tasks but not in systematically organizing information on a large scale. The document examines issues that arise when small projects expand and ways to help scientists address data management challenges as projects increase in scale and collaboration.

1) Java is a programming language created by James Gosling at Sun Microsystems in 1995. It is an object-oriented language designed to be portable and robust.
2) Java applications can run on many platforms due to its "write once, run anywhere" ability. This is enabled by the Java Virtual Machine, which converts Java code into code that devices can understand.
3) Java has several editions for different use cases, including the Java Standard Edition for desktop apps, the Java Enterprise Edition for enterprise software, and the Java Micro Edition for limited devices.
This document discusses an ontology-based platform for personalizing Java applications to better utilize resources in the host environment. It proposes using an intelligent Java agent to scan the host for native libraries and insert Java Native Interface (JNI) calls into Java bytecode to improve performance. The paper outlines the Java runtime environment and virtual machine architecture to provide context. It describes using JNI to allow Java code to call native methods in order to leverage host environment features. The proposed personalization aims to converge Java performance with platform-dependent languages like C++.
This paper presents a personalization platform to adapt Java based applications to Host
Environment; this is to converge the performance and reliability toward platform dependant (e.g.,
like C++). Intelligent Java agent is designed to perceive Host Environment and embed Java Native
Interfaces (JNI) to Java program at Byte Code level. Intelligent Java agent scans host machines for
low level libraries; which are normally DLL (Dynamic Link Library) files, and list them in table.
The personalized program is executed at two performance levels, first level is the impersonalized
level (i.e., not handled by the agent) which is low performance and the second is the personalized
level which is the high level in term of performance due to injecting JNI interfaces

Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.
