In this paper, we will discuss ten programming languages: C++, C#, Java, Groovy, JavaScript, PHP, Schalar, Scheme, Haskell and AspectJ. We summarize and compare these ten languages on ten different criterion. For example, Default more secure programming practices, Web applications development, OO-based abstraction and etc. At the end, we will give our conclusion that which languages are suitable and which are not for using in some cases. We will also provide evidence and our analysis on why some language are better than other or have advantages over the other on some criterion. 1 Introduction Since there are hundreds of programming languages existing nowadays, it is impossible and inefficient

COURSE INFORMATION Required Textbook Python Crash Course: A Hands-On, Project-Based Introduction to Programming by Eric Matthews ISBN-10: 1593276036 OR ISBN-13: 978-1593276034 COURSE DESCRIPTION This course is designed to introduce business analytics programming in Python to students. Students will learn programming foundations, application development in Python, and how to integrate Python applications with business operations in this class. COURSE OBJECTIVES Upon successfully completing this course, students will be able to “do something useful with Python”. Identify/characterize/define a problem Design a program to solve the problem Create executable code Read most Python code Write basic tests GRADING Labs (A Maximum of 50 Points) A number of labs will be given during the semester (almost every class). The labs will be handed out in-class and are usually due at the end of the class (or at the end of the day – instructor discretion). The purpose of the labs is student learning, rather than student testing. Projects (A Maximum of 50 Points) 2 projects will be given during the semester. You can get a maximum of 20 points for the first project, and 30 for the next.

  • Practical Considerations of Open Source Delivery Eric Lyness Microtel, LLC NASA GSFC Planetary Environments Laboratory, Code
    Practical Considerations of Open Source Delivery Eric Lyness Microtel, LLC NASA GSFC Planetary Environments Laboratory, code 699 Software Lead for Mars Organic Molecule Analyzer The days are long gone when one developer wrote an application that provided the data processing for a project. Code is now developed on many platforms, in many languages and often by scientists and engineers, not just professional programmers. This paper discusses the practical difficulties with delivering the software to support a typical research project. The most difficult task for projects delivering source code to an open source repository might be simply defining what is meant by “source code.” Projects frequently rely on fragile, ad hoc collections of code in many forms from many sources that have been used and modified over many years by an array of developers with different skills and preferences. Deliveries of the typical jumble of software products supporting research projects to a public archive would be of limited value and very limited lifetime. Conglomerations A single project could rely on code existing as: 1. Small scripts in Python or Perl along with some Bash scripts. 2. Applications in C++. 3. Web-based java script applications 4. Code in commercial languages such as LabVIEW, Matlab, IDL, Igor or numerous others. 5. Code embedded in spreadsheets using Visual Basic for Applications or formulas. This devolution of code into different languages is an inevitable result of laboratory work. It’s caused by two things: First the typical data flow of a research project and second the heritage code of the organization. Whatever the cause, the myriad code used by a project will result in havoc to deliver to an open source archive.

  • Space Sector
    Space Sector Interview: Eric Perlade, Are there any specific requirements for space applications? Space applications are either safety critical or mission critical, and Technical Account most have hard real-time constraints. Guiding a launcher or delivering positioning data requires precision and high reliability. The software Manager, AdaCore. has to be maintained for 10 years for satellites and 20 or more years for launchers with different versions. What’s more, the environment in which onboard software is running does not allow the usual patching methods. Patching is either impossible or else only achievable with limited capabilities. Why is the Ada language suitable for space applications? All those ingredients make Ada not only suitable for space applications but a very good fit, and it is widely used to develop onboard software. What we see in the space industry is the use of Ada for bare metal applications, that is, where the target platform does not have an underlying operating system. Ada also offers the flexibility and portability to run on native platforms and on embedded real-time operating systems, with advanced tasking capabilities. Because Ada is a general-purpose imperative programming language, you can use it to write software similarly to how you would do it in C or C++. You can write sequential programs (with a single thread of control), or, in a more advanced way, write concurrent programs with features that are high-level but efficient. You can develop software in Ada using object-oriented programming, or even contract-based programming and formal methods. What are Ada’s main attributes? The language has been designed with reliability and maintainability in mind.
