How To Generate Code Coverage Report Using JaCoCo-Maven Plugin

Aggregated on: 2023-01-19 01:59:23

Code coverage is a software quality metric commonly used during the development process that let’s you determine the degree of code that has been tested (or executed). To achieve optimal code coverage, it is essential that the test implementation (or test suites) tests a majority percent of the implemented code. There are a number of code coverage tools for languages like Java, C#, JavaScript, etc. Using the best-suited code coverage tool is important to understand the percentage of code tested and take appropriate actions to ensure that you achieve the ideal code coverage.

Efficiently Computing Permissions at Scale: Our Engineering Approach

Aggregated on: 2023-01-18 20:14:23

A few weeks ago, we introduced a new Role-based Access Management (RBAC) feature in the GitGuardian Internal Monitoring platform. This release resulted from several months of hard work where we had to thoroughly review our data model and implement a very resource-efficient permissions calculation mechanism. Therefore, I thought this was the perfect opportunity to offer a deep dive into the research, problems, and dead-end roads we encountered on this journey. Disclaimer: I’ll be using Django in my code examples, but the ideas can be generalized; however, a relational database is a stronger requirement.

Deploying Java Serverless Functions as AWS Lambda

Aggregated on: 2023-01-18 19:14:23

The AWS console allows the user to create and update cloud infrastructure resources in a user-friendly manner. Despite all the advantages that such a high-level tool might have, using it is repetitive and error-prone. For example, each time we create a Lambda function using the AWS console, we need to repeat the same operations again and again, and, even if these operations are intuitive and easy as graphical widget manipulations, the whole process is time-consuming and laborious. This working mode is convenient for rapid prototyping, but as soon as we have to work on a real project with a relatively large scope and duration, it doesn't meet the team's goals and wishes anymore. In such a case, the preferred solution is IaC (Infrastructure as Code). IaC essentially consists of using a declarative notation in order to specify infrastructure resources. In the case of AWS, this notation expressed as a formalism based on a JSON or YAML syntax is captured in configuration files and submitted to the CloudFormation IaC utility.

Using the PostgreSQL Pager With MariaDB Xpand

Aggregated on: 2023-01-18 16:44:23

I'm not an anti-GUI person. In fact, I wrote three books about web GUI development with Java. However, I also like the command-line interface (CLI), especially text-based UIs. After a year of exploring MariaDB and the DevOps world, I got to discover and play with many text-based CLI tools that I didn't know even existed. These tools are especially useful when connecting to remote servers that don't have a GUI. One special CLI tool that I frequently use is the mariadb SQL client (or mysql in the MySQL world)—a CLI program used to connect to MariaDB-compatible databases. With it, you can send SQL queries and other commands to the database server.

Debugging Threads and Asynchronous Code

Aggregated on: 2023-01-18 00:59:22

This week, we’ll discuss one of the harder problems in programming: threading. For many cases, threading issues aren’t as difficult to debug. At least, not in higher abstractions. Asynchronous programming is supposed to simplify the threading model but oftentimes it makes a bad situation worse by detaching us from the core context. We discuss why that is and how debuggers can solve that problem. We also explain how you can create custom asynchronous APIs that are almost as easy to debug as synchronous applications! Transcript Welcome back to the seventh part of debugging at scale where we don’t treat debugging like taking out the garbage.

How To Create a Stub in 5 Minutes

Aggregated on: 2023-01-17 21:44:22

If you’re developing an application that sends REST requests to the API of another service, mocks and stubs will probably help with your testing. Mock objects are used in unit tests: a call to another service is simulated. A test stub is an HTTP server that completely mimics the behavior of the service with which we plan to interact during the production use of our application. But using this service is not suitable for testing purposes. The scope of stubs is wide: regression testing, load testing, debugging, and more. Today, I will be as brief and, to the best of my ability, clearly talk about how to create stubs in a matter of minutes using the WireMock tool.

The system catalog views are used to show the information of the database engine. The catalog views can be used to display the meta-data of the SQL Server database. The catalog views inherit the information from the SQL Server metadata tables. For example, sys.tables view inherits the data from sys.objects catalog view.

Why Many Developers Don’t Write or Give Talks and How To Overcome Challenges

Aggregated on: 2023-01-17 19:29:22

I asked on Twitter and LinkedIn why many developers don’t write or give talks, and I was amused by the response I received. This article is about that. The Problems It turns out developers do not write blogs or give presentations for a variety of reasons. Some developers may believe they lack interesting experiences or information to share or feel that they are not experts in their profession. Others may be shy or fearful of public speaking. Another reason is due to their hectic schedules, individuals may not have time to write about or discuss their jobs.

Legacy VM Backup vs. Native VM Backup

Aggregated on: 2023-01-17 13:59:22

Today's modern VMware backup solutions offer powerful backup and replication features for the enterprise data center environment. When we think about how far we have come with backup technologies and compare them with the legacy backup solutions of days past, we see the tremendous advantages of using a "native" VM backup solution over a "legacy" VM backup solution. What are legacy VM backup solutions, and what do they do when it comes to backing up virtual machines? What are native backup solutions in this regard? How do these two compare, and why do we want to use a native VM backup solution? Legacy VM Backup Solutions Legacy VM backup solutions are essentially the same backup solutions that have been used on physical workloads for years and then moved over to virtual machines. The same technology, tools, and methodologies are used with virtual machines as with physical machines. Typically, we may think about a "backup agent" being installed inside the guest operating system for the backup solution to be able to back up virtual machines. Suppose the legacy solution is able to utilize (even in a crude way) the VMware data protection APIs. In that case, they generally still need some sort of agent to be able to perform application-aware backups or granular file restores.

5 Data Mesh Best Practices From 4 Data Leaders

Aggregated on: 2023-01-17 13:29:22

Data leaders across industries are embracing data mesh. However, it’s easy to be skeptical based on past trends that have come and gone. Those fads forced us to adjust our strategy, overhaul our tech, or re-skill our teams. But the reason data teams want to understand better how to implement data mesh is that it solves genuine pain points. Specifically, the problems created by an exhaust-friendly data lake and the all-too-often disconnect between teams – of data producers, data consumers, and those in between – that contribute to the value chain of a data product.

There's been a lot of chatter around Chat GPT. In this article, I'm briefly explaining what language models are, how Chat GPT differs from other language models, and how small players coming into this exciting space build sustainable products that can survive the competition. What Are Language Models? Language modeling is at the core of Natural language processing, trying to predict the probability of the following sequence of words given the past sequence of words in a text. E.g., The model tries to learn that the word "blue" is more likely to follow the sequence of words "The water is clear and the sky is <>" than the words red/green/ocean, etc. Suppose the model can learn the next sequence of words/sentences/characters. In that case, this model can be used in various tasks like Autocomplete, speech recognition, machine translation, text generation, etc., along with other classification models.

Unlocking the Power of Polymorphism in JavaScript: A Deep Dive

Aggregated on: 2023-01-16 20:44:22

Polymorphism is a concept in object-oriented programming that allows objects of different types to be treated as objects of a common type. This allows for more flexible and reusable code and a more intuitive way of thinking about objects and their interactions. Overview In JavaScript, polymorphism is implemented through the use of prototypes and prototypal inheritance. Every object in JavaScript has a prototype, which is another object that it inherits properties and methods from. This allows for the creation of a chain of prototypes, where an object can inherit from another object, which in turn inherits from another object, and so on.

Handling Virtual Threads

Aggregated on: 2023-01-16 19:44:22

Virtual threads were released as a preview feature in September 2022 as a part of Java 19. They are lightweight versions of platform threads. Unlike legacy platform threads, the memory footprint of a virtual thread is minute. For an in-depth introduction to virtual threads, check out the following article. Virtual threads support the creation of a thread per unit of work model, no matter how many tasks we have to process. Instead of reusing legacy platform threads via thread pools, we can have a virtual thread for each task. Following the programming flow for each task on a per-thread basis simplifies the coding and eases the maintenance. In particular, virtual threads shine with I/O requests to support concurrent high-throughput I/O programming.

How To Validate Three Common Document Types in Python

Aggregated on: 2023-01-16 15:59:21

Regardless of the industry vertical we work in – whether that be somewhere in the technology, e-commerce, manufacturing, or financial fields (or some Venn diagram of them all) – we mostly rely on the same handful of standard document formats to share critical information between our internal teams and with external organizations. These documents are almost always on the move, bouncing across our networks as fast as our servers will allow them to. Many internal business automation workflows, for example – whether written with custom code or pieced together through an enterprise automation platform – are designed to process standard PDF invoice documents step by step as they pass from one stakeholder to another. Similarly, customized reporting applications are typically used to access and process Excel spreadsheets which the financial stakeholders of a given organization (internal or external) rely on. All the while, these documents remain beholden to strictly enforced data standards, and each application must consistently uphold these standards. That’s because every document, no matter how common, is uniquely capable of defying some specific industry regulation, containing an unknown error in its encoding, or even - at the very worst - hiding a malicious security threat behind a benign façade. As rapidly evolving business applications continue to make our professional lives more efficient, business users on any network place more and more trust in the cogs that turn within their suite of assigned applications to uphold high data standards on their behalf. As our documents travel from one location to another, the applications they pass through are ultimately responsible for determining the integrity, security, and compliance of each document’s contents. If an invalid PDF file somehow reaches its end destination, the application which processes it – and, by extension, those stakeholders responsible for creating, configuring, deploying, and maintaining the application in the first place – will have some difficult questions to answer. It’s important to know upfront, right away, whether there are any issues present within the documents our applications are actively processing. If we don’t have a way of doing that, we run the risk of allowing our own applications to shoot us in the foot.

Type conversion in TypeScript can either be implicit (this is automatically done during the code execution) or explicit (this is done by the developer). The TypeScript file will check for errors after converting the code from JavaScript to TypeScript, as TypeScript has strict type-checking.

It is not a new discovery that a classy and user-friendly UI is necessary to complete your great idea into a successful app. Every developer knew this struggle until 2011, when Facebook first used React for its newsfeed. Or is there something else?

You are going to encounter a number of issues as a Python developer. Mastering the syntax of coding isn’t enough to write functioning, stable applications. You also have to familiarize yourself with different challenges the final application might deal with, including Python security risks. Many of the discussions about developing secure applications focus on using machine learning to protect customers, such as helping them avoid holiday scams. However, it is equally important to ensure the applications themselves are not vulnerable to cybercriminals.
