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 Reguated Industries Capgemini Template.Indd
    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

  • Advanced Tcl E D
    PART II I I . A d v a n c Advanced Tcl e d T c l Part II describes advanced programming techniques that support sophisticated applications. The Tcl interfaces remain simple, so you can quickly construct pow- erful applications. Chapter 10 describes eval, which lets you create Tcl programs on the fly. There are tricks with using eval correctly, and a few rules of thumb to make your life easier. Chapter 11 describes regular expressions. This is the most powerful string processing facility in Tcl. This chapter includes a cookbook of useful regular expressions. Chapter 12 describes the library and package facility used to organize your code into reusable modules. Chapter 13 describes introspection and debugging. Introspection provides information about the state of the Tcl interpreter. Chapter 14 describes namespaces that partition the global scope for vari- ables and procedures. Namespaces help you structure large Tcl applications. Chapter 15 describes the features that support Internationalization, includ- ing Unicode, other character set encodings, and message catalogs. Chapter 16 describes event-driven I/O programming. This lets you run pro- cess pipelines in the background. It is also very useful with network socket pro- gramming, which is the topic of Chapter 17. Chapter 18 describes TclHttpd, a Web server built entirely in Tcl. You can build applications on top of TclHttpd, or integrate the server into existing appli- cations to give them a web interface. TclHttpd also supports regular Web sites. Chapter 19 describes Safe-Tcl and using multiple Tcl interpreters. You can create multiple Tcl interpreters for your application. If an interpreter is safe, then you can grant it restricted functionality.

  • Theta Engineering Firmware Coding Conventions
    Theta Engineering Firmware Coding Conventions Best Practices What constitutes “best practice” in software development is an ongoing topic of debate in industry and academia. Nevertheless, certain principles have emerged over the years as being sound and beneficial. In taking a conservative stance on this topic, we will avoid the most recent and contentious ideas and stick with the ones that have withstood the test of time. The principles we will use in the development of firmware are: o Object oriented design – Even though we are not programming in an “object oriented language” per se, the principles of object oriented design are still applicable. We will use a C module to correspond to an “object”, meaning a body of code that deals with a specific item or conceptually small zone of functionality, and encapsulates the code and data into that module. o Separation of interface and implementation – Each module will have a .c file that comprises the implementation and a .h file specifying the interface. Coding details and documentation pertaining to the implementation should be confined to the .c file, while items pertaining to the interface should be in the .h file. o Encapsulation – Each module should encapsulate all code and data pertaining to its zone of responsibility. Each module will be self contained and complete. Access to internal variables if necessary will be provided through published methods as described in the header file for the module. A module may use other appropriate modules in order to do its job, but may do so only through the published interface of those modules.

They can be established for iii) understand if a tool is able to check a certain rule, iv) many reasons, ranging from improving the readability of code configure a tool to check a certain rule, etc. to avoiding the introduction of security flaws.

  • Best Practice Programming Techniques for SAS® Users
    PharmaSUG 2016 – Paper AD11 Best Practice Programming Techniques for SAS® Users Kirk Paul Lafler, Software Intelligence Corporation, Spring Valley, California Mary Rosenbloom, Lake Forest, California Abstract It’s essential that SAS® users possess the necessary skills to implement “best practice” programming techniques when using the Base-SAS software. This presentation illustrates core concepts with examples to ensure that code is readable, clearly written, understandable, structured, portable, and maintainable. Attendees learn how to apply good programming techniques including implementing naming conventions for datasets, variables, programs and libraries; code appearance and structure using modular design, logic scenarios, controlled loops, subroutines and embedded control flow; code compatibility and portability across applications and operating platforms; developing readable code and program documentation; applying statements, options and definitions to achieve the greatest advantage in the program environment; and implementing program generality into code to enable its continued operation with little or no modifications. Introduction Code is an intellectual property and should be treated as a tangible asset by all organizations. Best practice programming techniques help to clarify the sequence of instructions in code, permit others to read code as well as understand it, assist in the maintainability of code, permit greater opportunity to reuse code, achieve measurable results, reduce costs in developing and supporting code, and assist in performance improvements (e.g., CPU, I/O, Elapsed time, DASD, Memory). Best Practice Concepts A best practice programming technique is a particular approach or method that has achieved some level of approval or acceptance by a professional association, authoritative entity, and/or by published research results. Successful best practice programming techniques translate into greater code readability, maintainability and longevity while ensuring code reusability.

At this date copyright is owned by the author. Signature: . Date: . Abstract Despite decades of research aiming to ameliorate the difficulties of creat- ing software, programming still remains an error-prone task. Much work in Computer Science deals with the problem of specification, or writing the right program, rather than the complementary problem of implementation, or writing the program right. However, many desirable software properties (such as portability) are obtained via adherence to coding standards, and there- fore fall outside the remit of formal specification and automatic verification. Moreover, code inspections and manual detection of standards violations are time consuming. To address these issues, this thesis describes Exstatic, a novel framework for the static detection of coding standards violations. Unlike many other static checkers Exstatic can be used to examine code in a variety of lan- guages, including program code, in-line documentation, markup languages and so on.
