Reasons are: The program is large. Even with fast computers, editing and compiling a single file with a million lines leads to unnecessary delays. The program is developed by several people. Different programmers cannot easily edit the same file at the same time. (There is software for collaborative work that permits that, but it is still a research topic.) A large program is easier to understand if it is divided into natural units. E.g. each module defines one data type with its operations.

Article Reading Qualitative Studies Margarete Sandelowski University of North Carolina at Chapel Hill Chapel Hill, North Carolina, USA Julie Barroso University of North Carolina at Chapel Hill Chapel Hill, North Carolina, USA © 2002 Sandelowski et al. This is an Open Access article distributed under the terms of the Creative Commons Attribution License (http://creativecommons.org/licenses/by/2.0), which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Abstract In this article, the authors hope to shift the debate in the practice disciplines concerning quality in qualitative research from a preoccupation with epistemic criteria toward consideration of aesthetic and rhetorical concerns. They see epistemic criteria as inevitably including aesthetic and rhetorical concerns. The authors argue here for a reconceptualization of the research report as a literary technology that mediates between researcher/writer and reviewer/reader. The evaluation of these reports should thus be treated as occasions in which readers seek to make texts meaningful, rather than for the rigid application of standards and criteria. The authors draw from reader-response theories, literature on rhetoric and representation in science, and findings from an on-going methodological research project involving the appraisal of a set of qualitative studies. Keywords: Reader-response, reading, representation, rhetoric, qualitative research, quality criteria, writing Acknowledgments: We thank the members of -

The Programming Language Concurrent Pascal
IEEE TRANSACTIONS ON SOFTWARE ENGINEERING, VOL. SE-I, No.2, JUNE 1975 199 The Programming Language Concurrent Pascal PER BRINCH HANSEN Abstract-The paper describes a new programming language Disk buffer for structured programming of computer operating systems. It e.lt tends the sequential programming language Pascal with concurx:~t programming tools called processes and monitors. Section I eltplains these concepts informally by means of pictures illustrating a hier archical design of a simple spooling system. Section II uses the same enmple to introduce the language notation. The main contribu~on of Concurrent Pascal is to extend the monitor concept with an .ex Producer process Consumer process plicit hierarchy Of access' rights to shared data structures that can Fig. 1.

Revoke Obfuscation Report
Revoke-Obfuscation: PowerShell Obfuscation Detection Using Science Daniel Bohannon @danielhbohannon | Lee Holmes @Lee_Holmes Revoke-Obfuscation is the result of industry research collaboration between Daniel Bohannon - Senior Applied Security Researcher at Mandiant/FireEye, and Lee Holmes – Lead Security Architect of Azure ManaGement at Microsoft. Background By far the most prevalent delivery and execution vehicle for malware in the industry today is basic malicious executables and malicious documents. While not represented accurately by its popularity in the news, a small portion of the current malware ecosystem leverages PowerShell as part of its attack chain. Of malware that uses PowerShell, the most prevalent use is the garden-variety stager: an executable or document macro that launches PowerShell to download another executable and run it. Despite its relative statistical rarity, development of malicious and offense-focused PowerShell techniques has been a rich field of innovation. Commercial products have started to react to these techniques in several ways. Because they are often delivered as script files, Antivirus vendors have long had the ability to write signatures that block malicious PowerShell scripts. With the release of Windows 10, some vendors have additionally begun to implement support for Windows’ Antimalware Scan Interface. This interface gives Antivirus vendors the ability to implement deep content scanning, providing visibility as each stage of malware fetches and dynamically executes new instructions from a remote network location. In addition to antivirus signatures, many SIEM vendors have started to implement alerting based on command-line parameters that are frequently used in malicious contexts. Palo Alto provides an excellent survey of commonly-used malicious PowerShell command-line arguments in their post, Pulling Back the Curtains on EncodedCommand PowerShell Attacks. -
How to Evade Application Whitelisting Using REGSVR32
EXTERNAL/INTERNAL, RED TEAM, RED TEAM TOOLS CASEY SMITH, COM+ SCRIPLETS, DLL, FOLLOW US 10 SUBTEE, WEVADE, WHITELISTING MAY 2017 How to Evade Application Whitelisting Using REGSVR32 Jo Thyer // I was recently working on a Red Team for a customer that was very much up to date with their defenses. This customer had tight egress controls, perimeter proxying, strong instrumentation, and very tight application whitelisting controls. My teammate and I knew that we would have to work very hard to get command and control outbound from this environment, and that would be after obtaining physical access (yet another signicant challenge). Create PDF in your applications with the Pdfcrowd HTML to PDF API PDFCROWD The week before going on-site, we began to LOOKING FOR research all of the various methods for SOMETHING? potential application whitelisting bypass. We assumed the best case defensive scenario whereby the customer would have all binary execution blocked with the exception of specic applications permitted. In prior tests SUBSCRIBE TO THE with other customers and this same BHISBLOG customer, we had used “rundll32.exe” to execute DLL content. This method is really useful if you can host shellcode Don't get left in the dark! Enter within a DLL, and have a nice controlled entry point. In the Metasploit case, the your email address and every DLL entry point is named “Control_RunDLL”. While this might evade time a post goes live you'll get instant notication! We'll also whitelisting, we also knew this old trick had been played before and we likely add you to our webcast list, so could not count on it again. -
