In order to perform structured tests, a general description of the task as found in most development models is not sufficient. Besides integrating testing into the development process it is also necessary to provide a detailed test procedure. The development task consists of the process phases test planning and control, analysis and design, implementation and […]

A microservice architecture is made of single responsibility-focused services that are small, independently and deployable. A complete business application can be obtained aggregating and orchestrating this kind of service. These services are independent of each other, giving you the ability to easily test and deploy each one individually. . A single instance of a microservice […]

One of the most useful and emerging applications in the ML domain nowadays is using the transfer learning technique; it provides high portability between different frameworks and platforms. Once you’ve trained a neural network, what you get is a set of trained hyperparameters’ values. For example, LeNet-5 has 60k parameter values, AlexNet has 60 million, and VGG- 16 has about 138 million […]

Much like we gain knowledge about the behavior of the physical universe via the scientific method, we gain knowledge about the behavior of our software via a system of assertion, observation, and experimentation called “testing.” There are many things one could desire to know about a software system. It seems that most often we want […]

Continuous Integration The first step to delivering consistent and high-quality software is Continuous Integration (CI). CI is all about ensuring your software is in a deployable state at all times. That is, the code compiles and the quality of the code can be assumed to be of reasonably good quality. Source control CI starts with […]

A deep-belief network can be defined as a stack of restricted Boltzmann machines in which each RBM layer communicates with both the previous and subsequent layers. The nodes of any single layer don’t communicate with each other laterally. This stack of RBMs might end with a Softmax layer to create a classifier, or it may […]

First Class Function and Higher Order Function One of the key factors in Scala that beautifully blends functional paradigm into object-oriented paradigm is that functions are objects. In functional programming, functions are first-class citizens. A first-class function is a function that can be – Assigned to variables, – Passed as an argument to the other […]

Expression-Oriented Programming In expression-oriented programming every statement is an expression. To understand EOP, you have to understand the difference between a statement and an expression. A statement executes code, but does not return any value, for example: customer.computeDiscount() An expression returns value. Expressions are blocks of code that evaluate to a value as seen here: […]

Introducing RxJava To write reactive programs, we need a library or a specific programming language, because building something like that ourselves is quite a difficult task. Java is not really a reactive programming language (it provides some tools like the java.util.Observable class, but they are quite limited). It is a statically typed, object-oriented language, and […]

Nowadays, the term reactive programming is trending. Libraries and frameworks in various programming languages are emerging. Blog posts, articles and presentations about reactive programming are being created. Big companies, such as Facebook, SoundCloud, Microsoft, and Netflix, are supporting and using this concept. So we, as programmers, are starting to wonder about it. Why are people […]

Apache Spark is a cluster computing platform designed to be fast and general-purpose. On the speed side, Spark extends the popular MapReduce model to efficiently support more types of computations, including interactive queries and stream processing. Speed is important in processing large datasets, as it means the difference between exploring data interactively and waiting minutes […]

Cucumber is a very fun and cool tool for writing automated acceptance tests to support software development in the behavior-driven development (BDD) style. Getting ready In the BDD style, when a developer starts writing a test case, unlike writing a test method in TDD, he/she writes a “feature” belonging to a “story” which describes the […]
