Open Source Maintenance Is Community Organizing

Aggregated on: 2023-03-07 20:14:52

About six months ago, I wrote a piece about the state of open-source commercialization that garnered some notice. Almost immediately after that, Hacker News featured a problematic piece of prose on the front page. The title is “Fix it, Fork it, F*ck off” (censorship is mine). I think this is a great sample of where OSS is failing commercially and as a movement. A lot of the attention in OSS goes into the code of conduct policies (which are important), but not enough goes into what it takes to build a successful open-source project. It isn’t just the coding. I’d argue that coding is often less important than this. The Clash of Entitlement I understand where the author is coming from. He’s writing from frustration. We put a lot of work into our OSS project, and an entitled end user can be difficult. I agree some people go over the line, but in my experience, this is less than 0.1% of complaints. It’s rare to have a truly toxic user.

Direct socket connections can benefit all real-time applications since data can be sent or received anytime.

OWASP Kubernetes Top 10

Aggregated on: 2023-03-07 19:14:52

One of the biggest concerns when using Kubernetes is whether we are complying with the security posture and taking into account all possible threats. For this reason, OWASP has created the OWASP Kubernetes Top 10, which helps identify the most likely risks. OWASP's Top 10 projects are useful awareness and guidance resources for security practitioners and engineers. They can also map to other security frameworks that help incident response engineers understand Kubernetes threats. For example, MITRE ATT&CK techniques are also commonly used to register the attacker's techniques and help blue teams to understand the best ways to protect an environment. In addition, we can check the Kubernetes threat model to understand all the attack surfaces and main attack vectors.

How To Automate an API Gateway Migration

Aggregated on: 2023-03-07 18:29:52

Application Programming Interfaces (APIs) and API management are critical business assets. Today’s businesses are scaling APIs to meet different business needs with varying types of APIs, specifications, and functions across enterprise environments and complex architectures. Smart developers understand the business value of APIs and the need to have an API strategy independent of API gateways and host locations. Any workable API strategy must include gateway-agnostic APIs so they can run on-premises, in the cloud, or in a hybrid environment. APIs also must be easy to port to any new gateway provider. Whether the organization uses APIs custom-built by the DevOps team or purchased as Software-as-a-Service (SaaS), using APIs to connect applications throughout the organization requires effective API management. As the speed of business accelerates, APIs need to move faster as well, which means APIs need to be unified and self-service to be more agile and more portable.

The Three Daily Scrum Questions Won’t Die

Then, if the need should arise, the Developers adapt their plan to accomplish the Sprint Goal. While the theory may be generally accepted, applying the idea to the practice is more challenging. One of the recurring issues is the continued popularity of the “three Daily Scrum questions” from the Scrum Guide 2017. Let’s reflect on why answering these obsolete Daily Scrum questions negatively influences the Scrum team.

Managing Multiple APIs Using an Adapter Pattern

Aggregated on: 2023-03-07 18:29:52

Let's imagine the problem: Your company creates a B2B product that provides a service for some other companies. This service helps client-company to resolve very specific problems of their customers. This customer can communicate with our company web app and do some operations. The results of these operations should be reported to the other company side. Times go on, and now you have a few more clients that work by the same scheme. At first, you connect small companies one by one, but when you get to much bigger client companies, you discover that they use third-party API service providers and delegate all the integration problems to them. These API service providers act as a proxy for this toil of service reverse integration, which unifies the logic of cross-company communication on both sides. Due to the structure of presented business relationships, our company almost inevitably start to use a set of similar actions to communicate with dozens of different APIs for hundreds of clients in the future.

Modern Web Applications Authentication Using Face Recognition

Aggregated on: 2023-03-07 17:59:52

With the development of digital technology, information systems are also constantly upgraded. In the past, we have developed many mature WEB application information systems. With the continuous improvement of security level, the traditional way of account login is getting worse and worse in the current user experience. For example, after you log in to the WEB application on one computer, when you change to another computer and enter the correct account and password to log in, the WEB application cannot determine whether it is you or someone else who logged in illegally because of the change of IP address and device. It will ask you to verify whether it is you again through email or mobile phone number. This security measure is reasonable, but it will make real users feel uncomfortable. If we add the facial authentication function in the user authentication module to confirm the current login user, this security measure can avoid a bad user experience. Facial authentication can be easily performed using FACEIO, and the amount of code added to WEB applications is very small. It provides online JavaScript libraries, which can be directly referenced in front-end web pages. Below the code

Secure APIs: Best Practices and Measures

Aggregated on: 2023-03-07 14:44:52

An API (Application Programming Interface) acts as an intermediary between two distinct software applications, enabling seamless communication and data exchange. By providing a standardized interface, APIs offer developers the ability to access specific functionalities or data from another software application or service without the need to understand or modify the underlying code. This results in more efficient development processes, improved interoperability between applications, and enhanced overall functionality. APIs represent a potent resource for developers as they offer a uniform approach to accessing data and functionality from various software applications and services, resulting in the creation of more efficient and effective software solutions. This not only streamlines the development process but also enhances the overall performance and scalability of the resulting applications. As the usage of APIs continues to rise, it is imperative that they are appropriately secured. Many industry-wide threats are the result of excessive or sensitive data being leaked through APIs. To mitigate this risk, it is essential to implement a shift left approach, which involves securing APIs from the development stage to maintenance. By integrating security measures at the earliest stage of the development process, developers can reduce the risk of potential vulnerabilities being introduced into the API. Additionally, regular maintenance and updates can ensure that any new vulnerabilities are identified and promptly addressed. Overall, implementing a shift left approach is critical to ensuring the security and protection of data being transmitted through APIs.

Testing Repository Adapters With Hexagonal Architecture

Aggregated on: 2023-03-07 02:14:52

When applying hexagonal architecture (ports and adapters) with access to infrastructure elements like databases is done by the mean of adapters, which are just implementations of interfaces (ports) defined by the domain. In this article, we are going to provide two implementations of the same repository port, one in-memory and another based on JPA, focusing on how to test both implementations with the same set of tests. Context Many software solutions usually developed in the enterprise context have some state that needs to be persisted in a durable store for later access. Depending on the specific functional and non-functional requirements, selecting the correct persistence solution can be hard to make and most likely require an Architecture Decision Record (ADR) where the rationale of the selection, including alternatives and tradeoffs, is detailed. For persisting your application state, most likely, you will look at the CAP Theorem to make the most adequate decision.

Getting Started With Astro

Web development, like most technologies, moves in waves and cycles. Static websites were all we had in the beginning. But, pretty soon, developers were hacking together the first server-generated sites thanks to Perl and PHP. This was the advance that would eventually kickstart frameworks like Laravel, Django, or Rails. Mobile devices would come to change how people consume the web. So long server-generated websites, hello client-rendered applications. The next wave brought frameworks that could give users a more app-like experience—without reloads—like React or AngularJS.

Building Custom Solutions vs. Buy-and-Build Software

Aggregated on: 2023-03-06 23:14:52

The Challenges of Building a FIX Protocol The first day I was introduced to FIX was when I worked at an investment bank in London as a developer, I was told to write a feed handler to retrieve market data. Bear in mind that at this time, I knew nothing about FIX, apart from googling it for about 10 mins on the internet. With a touch of overconfidence and slight arrogance, I set to work coding a direct socket connection to the remote FIX endpoint, thinking, “How hard could it be?” So, What Is FIX? Financial Information eXchange (FIX) is both a market data format and a protocol: it is used by investment banks to place orders and receive market data and has become a global language in financial trading. The format of a FIX message controls how it is encoded. All FIX messages start with 8=FIX, which denotes the start of a FIX message. They then go on to list key and value pairs. The keys are represented as numbers (known as TagNumbers) followed by a = delimiter to delimit the values. Each key=value combination is then delimited by the \u0001 character, which is sometimes visually represented as either ^ or |. The value is often written in a semi-human-readable format. I say semi-human readable because most of the time it is human-readable, but all too often, FIX will use a single character to denote a state or type of message. These characters are not always that obvious. I agree that the character B for "Buy" and S for "Sell" makes sense, but other characters are used that make no sense. For example, D denotes a "New Order Single" message, which is a message that is often used when you wish to place an order with your counterparty.

Introduction Entrepreneurial ideas take advantage of the range of opportunities this field opens up, thanks to what is engineered by scientific profiles such as mathematicians or programmers. ALGORITHM. In Computer Science, an algorithm is a set of steps to perform a task. In other words, a logical sequence and instructions form a mathematical or statistical formula to perform data analysis. SENTIMENT ANALYSIS. Sentiment analysis refers to the different methods of computational linguistics that help to identify and extract subjective information from existing content in the digital world. Thanks to sentiment analysis, we can be able to extract a tangible and direct value, such as determining if a text extracted from the Internet contains positive or negative connotations. PREDICTIVE ANALYSIS. Predictive analysis belongs to the area of Business Analytics. It is about using data to determine what can happen in the future. The AP makes it possible to determine the probability associated with future events from the analysis of the available information (present and past). It also allows the discovery of relationships between the data that are normally not detected with less sophisticated analysis. Techniques such as data mining and predictive models are used. BUSINESS ANALYTICS. Business Analytics encompasses the methods and techniques used to collect, analyze, and investigate an organization's data set, generating insights that are transformed into business opportunities and improving business strategy. AE allows an improvement in decision-making since these are based on obtaining real data and real-time and allows business objectives to be achieved from the analysis of this data. BIG DATA. We are currently in an environment where trillions of bytes of information are generated every day. We call this enormous amount of data produced every day Big Data. The growth of data caused by the Internet and other areas (e.g., genomics) makes new techniques necessary to access and use this data. At the same time, these large volumes of data offer new knowledge possibilities and new business models. In particular, on the Internet, this growth begins with the multiplication in the number of websites, beginning search engines (e.g., Google) to find new ways to store and access these large volumes of data. This trend (blogs, social networks, IoT…) is causing the appearance of new Big Data tools and the generalization of their use. BUSINESS ANALYTICS (Business Analytics). Business Analytics or Business Analytics allows you to achieve business objectives based on data analysis. Basically, it allows us to detect trends and make forecasts from predictive models and use these models to optimize business processes. BUSINESS INTELLIGENCE Another concept related to EA is Business Intelligence (IE) focused on the use of a company's data to also facilitate decision-making and anticipate business actions. The difference with EA is that EI is a broader concept, it is not only focused on data analysis, but this is an area within EI. In other words, EI is a set of strategies, applications, data, technology, and technical architecture, among which is EA, and all this focus on the creation of new knowledge through the company's existing data. DATA MINING or data mining. Data Mining is also known as Knowledge Discovery in Database (KDD). It is commonly defined as the process of discovering useful patterns or knowledge from data sources such as databases, texts, images, the web, etc. Patterns must be valid, potentially useful, and understandable. Data mining is a multidisciplinary field that includes machine learning, statistics, database systems, artificial intelligence, Information Retrieval, and information visualization, ... The general objective of the data mining process is to extract information from set data and transform it into an understandable structure for later use. DATA SCIENCE. The opportunity that data offers to generate new knowledge requires sophisticated techniques for preparing this data (structuring) and analyzing it. Thus, on the Internet, recommendation systems, machine translation, and other Artificial Intelligence systems are based on Data Science techniques. DATA SCIENTIST. The data scientist, as his name indicates, is an expert in Data Science (Data Science). His work focuses on extracting knowledge from large volumes of data (Big Data) extracted from various sources and multiple formats to answer the questions that arise. DEEP LEARNING is a technique within machine learning based on neural architectures. A deep learning-based model can learn to perform classification tasks directly from images, text, sound, etc. Without the need for human intervention for feature selection, this can be considered the main feature and advantage of deep learning, called “feature discovery.” They can also have a precision that surpasses the human being. GEO MARKETING. The joint analysis of demographic, economic, and geographic data enables market studies to make marketing strategies profitable. The analysis of this type of data can be carried out through Geo marketing. As its name indicates, Geo marketing is a confluence between geography and marketing. It is an integrated information system -data of various kinds-, statistical methods, and graphic representations aimed at providing answers to marketing questions quickly and easily. ARTIFICIAL INTELLIGENCE. In computing, these are programs or bots designed to perform certain operations that are considered typical of human intelligence. It is about making them as intelligent as humans. The idea is that they perceive their environment and act based on it, focused on self-learning, and being able to react to new situations. ELECTION INTELLIGENCE. This new term, "Electoral Intelligence (IE)," is the adaptation of mathematical models and Artificial Intelligence to the peculiarities of an electoral campaign. The objective of this intelligence is to obtain a competitive advantage in electoral processes. Do you know how it works? INTERNET OF THINGS (IoT). This concept, the Internet of Things, was created by Kevin Ashton and refers to the ecosystem in which everyday objects are interconnected through the Internet. MACHINE LEARNING (Machine Learning). This term refers to the creation of systems through Artificial Intelligence, where what really learns is an algorithm, which monitors the data with the intention of being able to predict future behavior. WEB MINING. Web mining aims to discover useful information or knowledge (KNOWLEDGE) from the web hyperlink structure, page content, and user data. Although Web mining uses many data mining techniques, it is not merely an application of traditional data mining techniques due to the heterogeneity and semi-structured or unstructured nature of web data. Web mining or web mining comprises a series of techniques aimed at obtaining intelligence from data from the web. Although the techniques used have their roots in data mining or data mining techniques, they present their own characteristics due to the particularities that web pages present. OPEN DATA. Open Data is a practice that intends to have some types of data freely available to everyone, without restrictions of copyright, patents, or other mechanisms. Its objective is that this data can be freely consulted, redistributed, and reused by anyone, always respecting the privacy and security of the information. NATURAL LANGUAGE PROCESSING (NLP). From the joint processing of computational science and applied linguistics, Natural Language Processing (PLN or NLP in English) is born, whose objective is none other than to make possible the compression and processing aided by a computer of information expressed in human language, or what is the same, make communication between people and machines possible. PRODUCT MATCHING. Product Matching is an area belonging to Data Matching or Record Linkage in charge of automatically identifying those offers, products, or entities in general that appear on the web from various sources, apparently in a different and independent way, but that refers to the same actual entity. In other words, the Product Matching process consists of relating to different sources those products that are the same. Conclusion Today there are numerous data science and AI tools to process massive amounts of data. And this offers many opportunities: performing predictive and advanced maintenance, product development, machine learning, data mining, and improving operational efficiency and customer experience.

Your continuous delivery pipeline could also consist of many stages that should trigger these automated tests to verify defined quality gates before the software can move to the next stage and eventually into production (see Figure 1). Depending on the stage of your pipeline, your automated tests could range in complexity from unit, integration, end-to-end, and performance tests. When considering the quantity and complexity of tests, along with the possibility of having multiple stages in your pipeline, there could be many challenges when onboarding, executing, and evaluating the quality of your software before it is released. This article will describe some of these challenges. I will also provide some best practice guidelines on how your automated tests could follow a contract to help increase the delivery of your software to the market faster while maintaining quality. Following a contract helps to onboard your tests in a timely and more efficient manner. This also helps when others in your organization might need to troubleshoot issues in the pipeline.

Monolithic First

Aggregated on: 2023-03-06 03:29:51

In recent years, microservices architecture has become a popular buzzword in the software industry. The idea of breaking down a monolithic application into smaller, independent services that can be deployed and scaled independently sounds appealing. However, before you jump on the microservices bandwagon, there are a few things to consider. Monolithic architecture is an approach in which an entire application is built as a single, cohesive unit. It's a traditional architecture pattern that has been in use for a long time and has proven to be successful in many applications. With monolithic architecture, all the components of the application are tightly coupled, and it can be challenging to make changes to one component without affecting the others.

Leveraging Data Locality to Optimize Spark Applications

Aggregated on: 2023-03-05 04:14:51

Data locality is an essential concept in distributed computing, particularly in PySpark. It refers to the ability to process data where it is stored, rather than moving the data to where the processing is done. In this article, we will explore how to take advantage of data locality in PySpark to improve the performance of big data applications. 1. Use Cluster Manager The first step in taking advantage of data locality in PySpark is to use a cluster manager that supports it, such as Apache YARN. YARN ensures that the data is processed on the same node where it is stored, reducing data movement and improving performance.

Building a Certificate Authority (CA) Server for Your Servers and Applications Free of Cost

Aggregated on: 2023-03-04 17:14:51

In any organization, it is a best security practice to have an SSL certificate installed on servers, applications, and databases. To get an SSL certificate, the first step is to have or build a Certificate Authority (CA). SSL Certificates and CA make communication secure between client and server or application. If you do not have a CA ready internally or externally, you can not issue the certificate to any internal or external application. In that case, the risk of the application or server is at stake, as anybody can prove its identity and read critical data to harm the system. The CA is responsible for attesting to the identity of users, computers, and organizations. The CA authenticates an entity and assures the identity by issuing a digitally signed certificate. This article will focus on how to set up an internal CA for your organization. This provides better control to IT Admin over implementation and certificate life cycle management. You can use any number of SSL certificates free of cost. We will use a Windows server for it.

Ruby Adds Support for WebAssembly

Aggregated on: 2023-03-04 04:29:50

Ruby has joined the ranks of languages capable of targeting WebAssembly with its latest 3.2 release. This seemingly minor update might be the biggest thing that has happened to the language since Rails, as it lets Ruby developers go beyond the back end. By porting their code to WebAssembly, they can run it anywhere: on the front end, on embedded devices, as serverless functions, in place of containers, or on the edge. WebAssembly has the potential to make Ruby a universal language. What Is WebAssembly? WebAssembly (commonly shortened as Wasm) is a binary low-level instruction format that runs on a virtual machine. The language was designed as an alternative to JavaScript. Its aim is to run applications on any browser at near-native speeds. Wasm can be targeted from any high-level language like C, Go, Rust, and now also Ruby.
