On basic properties of DOS systems and languages

A. Ehrenfeucht, G. Rozenberg
1980 Information and Control  
A new type of grammar called a DOS system is introduced and investigated. Essentially it formalizes the notion of a context free grammar without variables that is generatively deterministic.  ...  Verraedt and P. Zeiger for comments concerning the first version of this paper. The authors gratefully acknowledge the financial support of NSF Grant MCS 79-03838.  ...  DOS SYSTEMS AND LANGUAGES In this section DOS systems and languages are introduced and illustrated by examples. Also a "forest representation" of (all derivations in) a DOS system is presented.  ...

The Limits of Language in Doing Systems Work [chapter]

Richard J. Boland
2000 IFIP Advances in Information and Communication Technology  
Doing systems work brings us to the limits of language as few human activities do.  ...  This paper sets five voices in dialogue to explore the limits of language in doing system work. Thefive voices, C.  ...  Acknowledgments The author appreciates the constructive criticism made by Geof Bowker and Ulrike Schultze on an earlier version of this paper, and the helpful discussion she had with Barbara Czarniawska  ...

What does the system of phonemes do?

Anatoly S. Liberman, University of Minnesota
2020 Vestnik of Saint Petersburg University Language and Literature  
System is one of the most important concepts of modern linguistics, including phonology, but it remains unclear in what sense the phonemes of a language form a system.  ...  Nowadays, phonemes are usually presented in the form of generative models, and the possibility to do so is understood as system's justification.  ...  Liberman University ofMinnesota, 9, Pleasant str., Minneapolis, MN 55455, USA aliber@umn.edu What does the system of phonemes do?For citation: Liberman A.

Eliminating Network Protocol Vulnerabilities Through Abstraction and Systems Language Design [article]

C. Jasson Casey, Andrew Sutton, Gabriel Dos Reis, Alex Sprintson
2013 arXiv   pre-print
We introduce a systems programming language with new abstractions that capture these constraints.  ...  Incorrect implementations of network protocol message specifications affect the stability, security, and cost of network system development.  ...  We do not expose pointers to the users of the language and drastically restrict heap allocation to certain language built-in types. Figure 2 shows the abstract syntax of the language.  ...

What do we really know about data flow languages?

Guido Salvaneschi
2016 Proceedings of the 7th International Workshop on Evaluation and Usability of Programming Languages and Tools - PLATEAU 2016  
In this paper, we advocate a systematic investigation of the design principles of data flow languages and suggest important research questions that urge to be addressed.  ...  While there is a general agreement that the data flow style simplifies the access to such complex systems compared to low level imperative APIs, this design has been substantiated by little evidence.  ...  These systems include PigLatin, Dryad, Spark and Spark Streaming.  ...

COMPUTER PROGRAMMING LANGUAGES IN 2020: WHAT WE USE|| WHO USES THEM|| AND HOW DO THEY IMPACT JOB SATISFACTION

2020 Issues in Information Systems  
Many other insights have been discovered including number of languages used, significant differences in language use by age and gender, and the relationship of language usage and job satisfaction.  ...  But how many of these languages are being actively used by today's software professionals? And are there differences in language usage by gender or age?  ...  Designing programs, algorithms, principles of programming languages, and systems are priority. What to include next is in question.  ...

1994 Proceedings of the ninth annual conference on Object-oriented programming systems, language, and applications - OOPSLA '94  
Each panelist was asked to provide his definition of team and a position statement reflecting on:  ...  Products might be built from objects, but most customers do not care much about objects.  ...  I acknowledge a wide variety of design techniques and programming languages that support a spectrum of design approaches that we collectively call "the object paradigm," but they all build on encapsulation  ...

Do language constructs for concurrent execution have impact on energy efficiency?

Gustavo Pinto
2013 Proceedings of the 2013 companion publication for conference on Systems, programming, & applications: software for humanity - SPLASH '13  
Nonetheless, the trade-off between performance and energy consumption in multicore applications is not so obvious.  ...  This study analyzed the performance and energy consumption of multicore applications, using three techniques to manage concurrent execution in a set of benchmarks.  ...  We can divide these attributes in two groups: internal (programming language construct, number of threads in use and resource usage -CPU and/or IO) and external (the clock frequency and the JVM implementation  ...
