There are repetitive patterns in strategies of manipulating source code. For example, modifying source code before acquiring knowledge of how a code works is a depth-first style and reading and understanding before modifying source code is a breadth-first style. To the extent we know there is no study on the influence of personality on them. The objective of this study is to understand the influence of personality on programming styles. We did a correlational study with 65 programmers at the University of Stuttgart. Academic achievement, programming experience, attitude towards programming and five personality factors were measured via self-assessed survey. The programming styles were asked in the survey or mined from the software repositories. Performance in programming was composed of bug-proneness of programmers which was mined from software repositories, the grades they got in a software project course and their estimate of their own programming ability. We did statistical analysis and found that Openness to Experience has a positive association with breadth-first style and Conscientiousness has a positive association with depth-first style. We also found that in addition to having more programming experience and better academic achievement, the styles of working depth-first and saving coarse-grained revisions improve performance in programming.

Enterprise architecture (EA) is a new approach that organizations should practice to align their business strategic objectives with information and communication technology (ICT). Enterprise Architecture encompasses a collection of different views and aspects of the enterprise which constitute a comprehensive overview when put together. Such an overview cannot be well-organized regardless of incorporating a logical structure called Enterprise Architecture Framework (EAF). EAF presents a transparent and comprehensive map of an organization that shows how all organization elements (business and IT) work together to achieve defined business objectives. Several distinctive EAF have been proposed, but many organizations are struggling with using these frameworks. This article try to eliminate the challenges of common and famous EAF by using Service Oriented (SO) paradigm. This service oriented EAF (SOEAF) named KASRA EAF. KASRA EAF involves a SO Roadmap that is compatible with ITIL and a Classification Schema comprises four rows and six columns.

Stream ciphering is an essential coding method for delay sensitive traffic such as voice and video. In this method the source sequence is combined with the output of a key stream generator using XOR The strength and robustness of this ciphering method lays in complexity of the key stream generator. A well-known method for generating key stream is pseudo-random number generator) which is based on LFSR. Recently the anti-random sequence has attained attraction and shown to have better statistical properties compared to pseudo-random numbers, so it appears be suitable for stream ciphering. The existing methods for generating anti-random numbers are highly time and memory consuming. This paper presents an approximate method for generating anti-random sequence, which is very simple and does not need large capacity of memory, while preserves the properties of the sequence. Moreover, we show that our method presents enough statistical complexity to fulfill the required security for stream ciphering.
