SQL performance tuning is a difficult task, especially when working with large amounts of data, where even slight changes can have a significant (positive or negative) influence on performance. A Database Administrator (DBA) will be in charge of most SQL performance adjustments in mid-sized and large businesses. However, believe me when we say that there are plenty of developers that have to perform DBA-like jobs.

An UnsupportedOperationException is a runtime exception in Java that occurs when a requested operation is not supported. For example, if an unmodifiable List is attempted to be modified by adding or removing elements, an UnsupportedOperationException is thrown. This is one of the common exceptions that occur when working with Java collections such as List, Queue, Set and Map. The UnsupportedOperationException is a member of the Java Collections Framework.

Variables are memory containers used to store information. In Java, every variable has a data type and stores a value of that type. Data types, or types for short, are divided into two categories: primitive and non-primitive. There are eight primitive types in Java: byte, short, int, long, float, double, boolean and char. These built-in types describe variables that store single values of a predefined format and size.

In the third and final article of our series on the OWASP Top 10 Web Application Security Risks, we’ll explore the lesser-known risks associated with the development of web applications on Rails when it comes to threats involving security misconfiguration, JSON escaping, etc.

As project needs evolve and expand, people need tools or software to enhance business operations and improve productivity. Over the past few years, several frameworks have been designed to aid the development of such tools and software, and among them webhooks are prominent ones. Webhooks are essentially tools used to automate business processes and allow organizations to provide interactive capabilities to customers.

The world is a digital place today. We fulfil most of our work, social and family tasks virtually, using the internet. The technology is now so universal, with so few barriers to entry, that practically anyone can connect to this global grid, no matter their technical skills. However, there is a flip side. Many people lack security awareness and knowledge, which can have drastic impacts on their social and financial life.

Syslog is a protocol that allows you to transmit and receive notifications in a predefined format from various network devices. Timestamps, event messages, severity, host IP addresses, diagnostics, and other information are included in the messages. It may transmit a range of severity levels, including level 0, which is an emergency, level 5, which is a warning, System Unstable, critical, and levels 6 and 7, which are Informational and Debugging.

Logging is used to track events that happen when an application runs. Logging calls are added to application code to record or log the events and errors that occur during program execution. In Python, the logging module is used to log such events and errors. An event can be described by a message and can optionally contain data specific to the event. Events also have a level or severity assigned by the developer. Logging is very useful for debugging and for tracking any required information.

Strings are a fundamental data type in most modern general-purpose programming languages. In Java, strings are defined as character sequences and are represented as immutable objects of the class java.lang.String which contains various constructors and methods for creating and manipulating strings . Below is an example of the string literal "rollbar" being assigned to two different variables a and b which both reference the same (automatically interned) String object.

Few lines of code, no matter how great your development team is, run at peak performance when they're originally developed. To discover the most effective technique to make code run quicker, it must be evaluated, debugged, and reviewed. How can software engineers and quality assurance engineers ensure that their code is fast, efficient, and ultimately valuable? The approach is to evaluate an application's code and discover and resolve performance bottlenecks using code profiling.

When building modern software architectures there can be many moving parts that while adding to the flexibility of software, can also make them more complex than ever before. With software now being built in smaller, more discrete components, issues can occur at many different layers across the stack, making them more difficult to track down.

Flaky tests are like meme stocks — many people have them, but no one knows what to do with them. Today, we will change that by diving into some common causes and, more importantly, solutions for flickering tests in Elixir. Elixir has many great primitives that let us run tests asynchronously, including immutable data, lightweight processes, and the Ecto SQL sandbox. Running tests asynchronously can greatly speed up your test suite, but can also increase the chance of flaky tests.

For any developer, console.log() is one of the most well-known javascript functions since it allows us to quickly check for errors in our code in some circumstances. If you're unfamiliar with it, it's a tool that Javascript developers use to debug their code. Almost all popular browsers include a console, which comes in helpful for debugging Javascript. To access your browser's console, you use the console object of Javascript.

Caching is a common technique for making your applications faster. It lets you avoid slow operations by reusing previous results. In this article, Ayo Asaiah walks us through the different options for caching in NodeJS applications.

Object-Oriented Programming has different concepts allowing developers to build logical code. One of these concepts is polymorphism. But what is polymorphism? Let’s discuss. Polymorphism is one of the core concepts of object-oriented programming (OOP) and describes situations in which something occurs in several different forms. In computer science, it describes the concept that you can access objects of different types through the same interface.

In computer programming, a function is a set of instructions that can be invoked to perform a particular task. In object-oriented programming (OOP), a method is a function that is typically associated with an object and models its behavior . In Java, methods can also be static, in which case they are part of a class definition and do not require an object to be created before they are invoked.

You can run your iOS UI tests way faster now on Bitrise. Wouldn’t it be the perfect time to use this decrease to run more of them?

In the KuppingerCole API Management and Security Leadership Compass 2021, Lead Analyst and CTO Alexei Balaganksi states, “Our general recommendation for customers remains the same: both API management and API security should not be considered as standalone, isolated components of your IT infrastructures.

The Python TypeError: unhashable type: 'list' usually means that a list is being used as a hash argument. This error occurs when trying to hash a list, which is an unhashable object. For example, using a list as a key in a Python dictionary will cause this error since dictionaries only accept hashable data types as a key. The standard way to solve this issue is to cast a list to a tuple, which is a hashable data type.

When a program encounters an exception during execution, it is terminated if the exception is not handled. By handling multiple exceptions, a program can respond to different exceptions without terminating it. In Python, try-except blocks can be used to catch and respond to one or multiple exceptions. In cases where a process raises more than one possible exception, they can all be handled using a single except clause.
