Object-Oriented Architecture

How to Choose Between Learning Python or R First


That makes R great for conducting complex exploratory data analysis. When you need to do heavy statistical analysis or graphing, R's your go-to. It's simpler to master than R if you have previously learned an object-oriented programming language like Java or C . In addition, because Python is an object-oriented programming language, it's easier to write large-scale, maintainable, and robust code with it than with R. Using Python, the prototype code that you write on your own computer can be used as production code if needed.

This is why most software developers use UML only when forced to.1 For example, the UML diagrams in Figures 1 and 2 portray the embedded software in a fax machine. While these diagrams are attractive, they do not even tell you which objects control which others. Which object is the topmost controller over this fax machine? Which object(s) control the Modem object?

Java is a programming language expressly designed for use in the distributed environment of the Internet. It was designed to have the "look and feel" of the C language, but it is simpler to use than C and enforces an object-oriented programming model. The exercises and presentation of content where extremely helpful. This is the first instruction manual I've used where I actually found myself reading all of the lessons instead of just skipping ahead to the exercises.

Releasing the World's Largest Street-level Imagery Dataset for Teaching Machines to See


Today we present the Mapillary Vistas Dataset--the world's largest and most diverse publicly available, pixel-accurately and instance-specifically annotated street-level imagery dataset for empowering autonomous mobility and transport at the global scale. Please take a moment to enjoy our early results on previously unseen test images below and by following #MapillaryVistas on Twitter and Facebook. To improve the annotation quality for each of our object classes and in order to draw probabilistic conclusions about the overall dataset annotation quality, we developed a 2-stage quality assurance (QA) process, where the second stage is guided by Bayesian statistical modeling. The second stage comprises a QA protocol based on which we can infer, with a confidence level of 99% and a given sample of validated images and corresponding instances, whether the annotators will fail or succeed to provide us with correctly labeled data (i.e.

Fear Of Failure Is The Biggest Obstacle to Teaching High Schoolers How To Program A Computer


What is the hardest concept for high school students to grasp when learning programming? The concept of an "object" is initially hard to understand, making it hard to decide how two objects should be related, and which methods should belong to which classes. At a higher level though, the hardest concept is a willingness to fail. This makes computer science one of the best academic subjects to teach the concept of embracing failure, even though most classes don't actually formally teach it.

MartinLogan Motion AFX review: Remarkable add-on speakers for object-oriented movie soundtracks


About a year an a half ago, I set up a Dolby Atmos, DTS:X and Auro-3D immersive audio setup in my basement with dedicated in-ceiling speakers. While overhead effects are superb, what really seals the deal is the way a Dolby Atmos mix creates a natural, enveloping sense of space throughout the movie. For example, when the rotund Mondoshawan aliens land in Egypt, the Motion AFX and the Atmos soundtrack created a superior, enveloping, natural surround field. I installed the front pair of Motion AFX on tall speaker stands and the rear pair on top of tower speakers.

The Python Tutorial -- Python 3.6.0 documentation


The Python interpreter and the extensive standard library are freely available in source or binary form for all major platforms from the Python Web site, https://www.python.org/, The same site also contains distributions of and pointers to many free third party Python modules, programs and tools, and additional documentation. For a description of standard objects and modules, see The Python Standard Library. The Python Language Reference gives a more formal definition of the language. After reading it, you will be able to read and write Python modules and programs, and you will be ready to learn more about the various Python library modules described in The Python Standard Library.

The Two Faces of #Microservices @CloudExpo @JPMorgenthal #AI #DevOps


Initial design of DOC attempted to solve the problem of simplifying developing complex distributed applications by applying object-oriented design principles to disparate components operating across networked infrastructure. In this model, DOC "hid" the complexity of making this work from the developer regardless of the deployment architecture through the use of complex frameworks, such as Common Object Request Broker Architecture (CORBA) and Distributed Component Object Model (DCOM). The RPC represented a way to call functionality inside of another applications across a network using the programming language function call constructs such as passing parameters and receiving a result. Web Services was eventually rebranded Application Programming Interface (API)--there is really no difference architecturally between a Web Service and an API--and JSON became the primary marshalling scheme for Web-based APIs.

Evolving R Tools and Practices


This leads me to say that languages like C and Java implement strong object oriented programming as these languages work hard to enforce meaningful invariants and hide implementation details from the user. In the Python programming language we also see object oriented semantics, but the implementation details are somewhat user visible because the programmer has direct access to the implementation of the object oriented effects (such as: self, __dict__, __doc__, __name__, __module__, __bases__). The object oriented semantics of Python are defined in terms of lookups against these structures, which are user visible (and alterable). For example R's common object oriented system S3 is visibly implemented as pasting method names together with class names (such as the method summary being specialized to models of class lm by declaring a function named "summary.lm").
