The Java Standards Committee (JSC) team is encouraging the use of CheckStyle (in the Eclipse IDE environment) to quickly scan Java code, to locate Java programming standard errors, find inconsistencies, and generally help build program conformance. The benefits of writing quality Java code infused with consistent coding and documentation standards is critical to the efforts of the Department of Veterans Affairs (VA). This document stands for the quality, readability, consistency and maintainability of code development and it applies to all VA Java programmers (including contractors). -

DEVSECOPS IN REGULATED INDUSTRIES ACCELERATING SOFTWARE RELIABILITY & COMPLIANCE TABLE OF CONTENTS 03... Executive Summary 04... Introduction 07... Impediments to DevSecOps Adoption 10... Playbook for DevSecOps Adoption 19... Conclusion EXECUTIVE SUMMARY DevOps practices enable rapid product engineering delivery and operations, particularly by agile teams using lean practices. There is an evolution from DevOps to DevSecOps, which is at the intersection of development, operations, and security. Security cannot be added after product development is complete and security testing cannot be done as a once-per-release cycle activity. Shifting security Left implies integration of security at all stages of the Software Development Life Cycle (SDLC). Adoption of DevSecOps practices enables faster, more reliable and more secure software. While DevSecOps emerged from Internet and software companies, it can benefit other industries, including regulated and high security environments. This whitepaper covers how incorporating DevSecOps in regulated Industries can accelerate software delivery, reducing the time from code change to production deployment or release while reducing security risks. This whitepaper defines a playbook for DevSecOps goals, addresses challenges, and discusses evolving workflows in DevSecOps, including cloud, agile, application modernization and digital transformation. Bi-directional requirement traceability, document generation and security tests should be part of the CI/CD pipeline. Regulated industries can securely move away -
Introducing 2D Game Engine Development with Javascript
CHAPTER 1 Introducing 2D Game Engine Development with JavaScript Video games are complex, interactive, multimedia software systems. These systems must, in real time, process player input, simulate the interactions of semi-autonomous objects, and generate high-fidelity graphics and audio outputs, all while trying to engage the players. Attempts at building video games can quickly be overwhelmed by the need to be well versed in software development as well as in how to create appealing player experiences. The first challenge can be alleviated with a software library, or game engine, that contains a coherent collection of utilities and objects designed specifically for developing video games. The player engagement goal is typically achieved through careful gameplay design and fine-tuning throughout the video game development process. This book is about the design and development of a game engine; it will focus on implementing and hiding the mundane operations and supporting complex simulations. Through the projects in this book, you will build a practical game engine for developing video games that are accessible across the Internet. A game engine relieves the game developers from simple routine tasks such as decoding specific key presses on the keyboard, designing complex algorithms for common operations such as mimicking shadows in a 2D world, and understanding nuances in implementations such as enforcing accuracy tolerance of a physics simulation. Commercial and well-established game engines such as Unity, Unreal Engine, and Panda3D present their systems through a graphical user interface (GUI). Not only does the friendly GUI simplify some of the tedious processes of game design such as creating and placing objects in a level, but more importantly, it ensures that these game engines are accessible to creative designers with diverse backgrounds who may find software development specifics distracting. -
Teaching Introductory Programming with Javascript in Higher Education
Proceedings of the 9th International Conference on Applied Informatics Eger, Hungary, January 29–February 1, 2014. Vol. 1. pp. 339–350 doi: 10.14794/ICAI.9.2014.1.339 Teaching introductory programming with JavaScript in higher education Győző Horváth, László Menyhárt Department of Media & Educational Informatics, Eötvös Loránd University, Budapest, Hungary [email protected] [email protected] Abstract As the Internet penetration rate continuously increases and web browsers show a substantial development, the web becomes a more general and ubiq- uitous application runtime platform, where the programming language on the client side exclusively is JavaScript. This is the reason why recently JavaScript is more often considered as the lingua franca of the web, or, from a different point of view, the universal virtual machine of the web. In ad- dition, the JavaScript programming language appears in many other areas of informatics due to the wider usage of the HTML-based technology, and the embedded nature of the language. Consequently, in these days it is quite difficult to program without getting in touch with JavaScript in some way. In this article we are looking for answers to how the JavaScript language is suitable for being an introductory language in the programming related subjects of the higher education. First we revisit the different technologies that lead to and ensure the popularity of JavaScript. Following, current approaches using JavaScript as an introductory language are overviewed and analyzed. Next, a curriculum of an introductory programming course at the Eötvös Loránd University is presented, and a detailed investigation is given about how the JavaScript language would fit in the expectations and requirements of this programming course. -

Node: A node is a running instance of elasticsearch which belongs to a cluster. Terminology Index: Collection of documents Shard: An index is split into elements known as shards that are distributed across multiple nodes. There are two types of shard, Primary and replica. By default elasticsearch creates 1 primary shard and 1 replica shard for each index.

UPTEC F 18029 Examensarbete 30 hp Juni 2018 Investigation and Implementation of a Log Management and Analysis Framework for the Treatment Planning System RayStation Elias Norrby Abstract Investigation and Implementation of a Log Management and Analysis Framework for the Treatment Planning System RayStation Elias Norrby Teknisk- naturvetenskaplig fakultet UTH-enheten The purpose of this thesis is to investigate and implement a framework for log management and analysis tailored to the treatment planning system (TPS) Besöksadress: RayStation. A TPS is a highly advanced software package used in radiation Ångströmlaboratoriet Lägerhyddsvägen 1 oncology clinics, and the complexity of the software makes writing robust code Hus 4, Plan 0 challenging. Although the product is tested rigorously during development, bugs are present in released software. The purpose of the the framework is to allow the Postadress: RayStation development team insight into errors encountered in clinics by Box 536 751 21 Uppsala centralizing log file data recorded at clinics around the world. Telefon: A framework based on the Elastic stack, a suite of open-source products, is 018 – 471 30 03 proposed, addressing a set of known issues described as the access problem, the Telefax: processing problem, and the analysis problem. Firstly, log files are stored locally on 018 – 471 30 00 each machine running RayStation, some of which may not be connected to the Internet. Gaining access to the data is further complicated by legal frameworks Hemsida: such as HIPAA and GDPR that put constraints on how clinic data can be handled. http://www.teknat.uu.se/student The framework allows for access to the files while respecting these constraints.
