[ANN] New article:
Dear all The following article had been peer-reviewed and accepted by The Python Papers. Title: A Python Module for FITS Files with full C Level Programming Functionality Abstract: A Python module for manipulating files in the FITS format is described. The module was constructed using the capabilites of ctypes to dynamically create foreign function interfaces from a C library. Here this was used to import the CFITSIO library into Python. I describe how this module can be used to call the functions from the C library in their near native form, and how one to manipulate FITS files in a style that Python programmers are accustomed. The ctypes and ctypeslib modules allows one to import all routines and data structures from the C library and avoids the need to manually write language bindings for each routine. Moreover, these modules allow the Python programmer to enjoy the full functionality of the the underlying C library. http://ojs.pythonpapers.org/index.php/tpp/article/view/250 Maurice Ling Co-EIC, The Python Papers -- http://mail.python.org/mailman/listinfo/python-list
[ANN] New article in The Python Papers Source Codes - COPADS III (Compendium of Distributions II): Cauchy, Cosine, Exponential, Hypergeometric, Logarithmic, Semicircular, Triangular, and Weibull
Hi everyone We have a new article in The Python Papers Source Codes. Title: COPADS III (Compendium of Distributions II): Cauchy, Cosine, Exponential, Hypergeometric, Logarithmic, Semicircular, Triangular, and Weibull Abstract: This manuscript illustrates the implementation and testing of eight statistical distributions, namely Cauchy, Cosine, Exponential, Hypergeometric, Logarithmic, Semicircular, Triangular, and Weibull distribution, where each distribution consists of three common functions – Probability Density Function (PDF), Cumulative Density Function (CDF) and the inverse of CDF (inverseCDF). These codes had been incorporated into COPADS codebase (https://github.com/copads/ copads) are licensed under Lesser General Public Licence version 3.

[ANN] New article published: TMSTAF – The Extended Use of STAF on Test Automation
http://ojs.pythonpapers.org/index.php/tpp/article/view/247 Abstract As software packages becomes increasingly large and complex, the time required for testing them, throughout the development lifecycle, has also increased. Because testing activities consume the majority of software Quality Assurance (QA) resources, a test platform was needed to speed up test cycles without any decrease in test result accuracy. The use of Python 2.6 scripting language to create a faster, automated testing platform is reported here. Trend Micro Software Testing Automation Framework (TMSTAF) was developed using Python 2.6, based on Software Testing Automation Framework (STAF), to improve automated testing. We found that TMSTAF not only decreased testing time, it provided faster process integration, test feedback, and improved overall software quality. Using the TMSTAF automation environment for development and execution is simple to set up. Test cases can be created for use in both manual and automated tasks, converted to automated scripts, and implemented with structur al and flexible mechanisms. Automation script pre-runs and debugging make troubleshooting more efficiently; TMSTAF test report data can be used to identify quality issues quickly. TMSTAF can be seamlessly integrated into the build release process, making it a smart option for software QA engineers. -- http://mail.python.org/mailman/listinfo/python-list
[ANN] 2 new articles in The Python Papers
Hi all I'm pleased to announce 2 newly published articles in The Python Papers (ojs.pythonpapers.org). FUSE’ing Python for Development of Storage Efficient Filesystem (http://ojs.pythonpapers.org/index.php/tpp/article/view/244) Abstract: Filesystem is a core component of a functional operating system. Traditional Filesystem development has been confined to the kernel space. A customized, purpose-built, and user-driven Filesystem development involves extensive knowledge of kernel internals, tools and processes. Alternatively, user-space Filesystems are preferred over the kernel space Filesystem, for ease of development, portability and developing prototypes Filesystems, particularly for intuitive abstraction of “non-file” objects. This paper proposes usage of FUSE kernel module to develop a functional Filesystem in user-space, titled “seFS”. Apart from offering convenience of user-space development, FUSE allows on-par features and functionality of a kernel space Filesystem. We demonstrate development of a Filesystem in Python on Ubuntu 11.04 system with Python-Fuse bindings. seFS Filesystem abstracts a SQLite database to store files data and metadata. By developing a Filesystem with Python-FUSE, we quickly solved the problem of efficient data management with online de-duplication and data compression. We discuss the internals of FUSE, its operation and implementation in this paper. An Artificial Life Simulation Library Based on Genetic Algorithm, 3-Character Genetic Code and Biological Hierarchy (http://ojs.pythonpapers.org/index.php/tpp/article/view/245) Abstract: Genetic algorithm (GA) is inspired by biological evolution of genetic organisms by optimizing the genotypic combinations encoded within each individual with the help of evolutionary operators, suggesting that GA may be a suitable model for studying real-life evolutionary processes. This paper describes the design of a Python library for artificial life simulation, Digital Organism Simulation Environment (DOSE), based on GA and biological hierarchy starting from genetic sequence to population. A 3-character instruction set that does not take any operand is introduced as genetic code for digital organism. This mimics the 3-nucleotide codon structure in naturally occurring DNA. In addition, the context of a 3-dimensional world composing of ecological cells is introduced to simulate a physical ecosystem. Using DOSE, an experiment to examine the changes in genetic sequences with respect to mutation rates is presented.

[ANN] New paper published (Volume 7 of The Python Papers) - Designing and Testing PyZMQ Applications
Link: http://ojs.pythonpapers.org/index.php/tpp/article/view/242 Abstract PyZMQ is a powerful and easy-to-use network layer. While ZeroMQ and PyZMQ are quite well documented and good introductory tutorials exist, no best-practice guide on how to design and especially to test larger or more complex PyZMQ applications could be found. This article shows a possible way to design, document and test real-world applications. The approach presented in this article was used for the development of a distributed simulation framework and proved to work quite well in this scenario. -- http://mail.python.org/mailman/listinfo/python-list
[ANN] New paper published (Volume 7 of The Python Papers) - High-Speed Data Shredding using Python
Link: http://ojs.pythonpapers.org/index.php/tpp/article/view/243 Abstract In recent years, backup and restore is a common topic in data storage. However, there’s hardly anybody mention about safe data deletion. Common data destruction methodology requires the wipe operation to fill the disk with zeros, then with random data, and then with zeros again. Three passes are normally sufficient for ordinary home users. On the down side, such algorithms will take many hours to delete a 2TB hard disk. Although current Linux utility tools gives most users more than enough security and data protections, we had developed a cross-platform standalone application that could expunge all confidential data stored in flash drive or hard disk. The data shredding software is written in Python, and it could overwrite existing data using user-defined wipe algorithm. This software project also explores the technical approaches to digital data destruction using various methodologies defined in different standards, which includes a selection of military-grade procedures proposed by information security specialists. The application operates with no limitations to the capacity of the storage media connected to the computer system, it can rapidly and securely erase any magnetic mediums, optical disks or solid-state memories found in the computer or embedded system. Not only does the software comply with the IEEE T10/T13 specifications, it also binds to the number of connectivity limited by the SAS/SATA buses. -- http://mail.python.org/mailman/listinfo/python-list

[ANN] Completion of The Python Papers Volume 4 Issue 1
Welcome to Issue 4 Volume 1 of The Python Papers. This marks our 4th year in business. It is my pleasure to announce 4 improvements made to The Python Papers Anthology. Firstly, we had created a class of editorial members in our team – the Editorial Reviewers (ER). This is in addition to the existing Editors- in-Chief (EIC) and Associate Editors (AE). In the words of our revised editorial policy, “ER is a tier of editors deemed to have in-depth expertise knowledge in specialized areas. As members of the editorial board, ERs are accorded editorial status but are generally not involved in the strategic and routine operations of the periodicals although their expert opinions may be sought at the discretion of EIC.” To this aspect, we are glad to have Jacob Kaplan-Moss (President, Django Software Foundation; Partner, Revolution Systems, LLC; Co-BDFL, Django) as our first ER. Welcome aboard. Secondly, we had adopted a fast publication scheme. In the past, accepted manuscripts will only be published on the release date in the month of April, August and December each year. With the use of Open Journal System, we are able to publish manuscripts as they are being accepted. This means that the release date in the month of April, August and December is now effectively our closing date for the issue. For example, manuscripts accepted after April 2009 will be routed to immediate publication in Volume 4 Issue 2. This is to being information faster to our readers, rather than waiting for a few months. Thirdly, we announce a set of manuscript templates for our authors and contributors for their manuscript preparation. As such, we had revamped our website (http://www.pythonpapers.org) to reflect these changes. Lastly, we are glad to announce the launch of our 2nd publication under The Python Papers Anthology – The Python Papers Source Codes (ISSN 1836-621X). TPPSC, for short, is a collection of software and source codes, usually associated with papers published in The Python Papers and The Python Papers Monograph. These codes are refereed for originality, accuracy, completeness, and lasting value. TPPSC will act as a developers codebook of high-quality, peer-reviewed codes. TPPSC is an annual publication using the same fast publication scheme. We thank all our readers and contributors for their continued support. Happy reading.

[ANN] The Python Papers Source Codes (Volume 1)
Hi everyone, It has been a few months in the cooking and I'm pleased to announce the publication and ISSN of The Python Papers Source Codes (ISSN 1836-621X). The Python Papers Source Code (TPPSC) will be a collection of code manuscripts, usually with a longer companion manuscript published in The Python Papers (TPP) or The Python Papers Monograph (TPPM). The purpose of TPPSC is modeled after "Collected Algorithms of the ACM". We will consider the following papers for TPPSC: * Algorithms: Implementation of an algorithm where it should be possible for a user to incorporate this software into a larger program, with the exception of standalone software. * Remarks: Brief report on a previously published algorithm, with the purpose of correcting / modifying the code. Details arguing for the modification should be provided with the modified code and patch file to used with the original implementation. * Translations: Translation of an algorithm / code from another programming language to Python, and should only be done if the algorithm still represents the current state of the art. * Certifications: Report on performance characteristics or verification of correctness by specification or from extensive testing of a previously published an algorithm / code. Certification reports do not change the original code; hence, a certification report usually do not contains codes. Each submission will usually consist of the following sections: 1. Title and author(s) affiliation 2. Abstract (usually a terse description of 1 or 2 sentences) 3. Description (about a page description of the purpose of the codes, including licence) 4. Code section (this is where the codes will be listed) 5. References 6. A compressed file of the codes files as supplementary materials For more details or to read our first paper under TPPSC, please go to http://ojs.pythonpapers.org/index.php/tppsc/issue/current All manuscripted for the periodicals under The Python Papers Anthology (http://ojs.pythonpapers.org) will be published once they are accepted. We look forward to your continued support. Cheers Maurice Ling Co-EIC, TPPA Maurice Ling -- http://mail.python.org/mailman/listinfo/python-list
[ANN] The Python Papers Volume 3 Issue 3
Hi everyone First of all, let me apologize for the delay of this issue of TPP. I understand that all of you had been anxiously waiting and I do sincerely apologize that Christmas and New Year celebrations are taking a toll on my time. Finally, here it is... Volume 3 Issue 3... And we are THIRD year in business. As usual, the issue can be found at http://ojs.pythonpapers.org/index.php/tpp/issue/current The 1-PDF per issue will be released shortly. Let me also take this opportunity to show our deep felt appreciation to all our supporters/readers and contributors. Without you, we will not have our day to serve the community. At this moment, I will also like to announce our new publication schedule - there will not be any!!! Oppss, that did not come out right... What I am trying to say is that from Volume 4 Issue 1 onwards, we will adopt the "fast publishing" method that many journals are using. We will be releasing each article out to the public as they are being accepted but each issue will be delimited by our usual “issue release” date. The “issue release” date is then our cutoff deadline to prepare the 1-PDF per issue file. This means that we will be serving new articles to everyone much faster than now and there will not be anymore meaningful publication schedules. Hence, let's gear up to another year of exciting Python development and a recovering economy. Happy reading Maurice Ling Co-EIC, The Python Papers Anthology -- http://mail.python.org/mailman/listinfo/python-list
