In software application development and deployment, teams typically work collaboratively and require managers to approve certain actions. Companies often adopt external systems like ticketing services, chat applications, external workflow tools such as Jira, or rely on manual emails to manage this coordination. These approaches can disrupt developer workflows.

ClickHouse is a high-performance, columnar database designed for analytics and big data applications. One of ClickHouse's standout features is its ability to perform filtering directly on compressed data, enabling faster results compared to traditional relational databases. While working with ClickHouse, you will often encounter the WHERE and PREWHERE clauses, both of which are used to filter data. But what is the difference between WHERE and PREWHERE, and when should you use one over the other?

Today’s fast-paced development environments require new approaches to testing. Enter continuous performance testing. Unlike traditional performance testing, automated continuous performance testing is part of every build, monitoring the application continuously under increased load. With continuous performance tests, organizations with lots of users can expect to improve the customer experience, prevent major outages, and find and resolve issues faster.

Strings are important concepts in programming and are data types that allow storage of character sequences. String methods are built-in functions that are called on a string to either get information or manipulate data. In Java, strings are treated as immutable data, therefore their values cannot be changed. To work with strings and perform operations on them, you need to understand string methods in Java and how they work.

When running tests, it's a great feeling to see dozens of green check marks indicating that a test suite is passing. It's especially gratifying after tackling a tricky bug or slogging through a tough feature. But those passing tests may be giving you a false sense of security. Often, bugs lurk in passing tests, undermining trust in the test suite and your application. Such tests can cause more harm than good, giving you a hearty pat on the back while hiding broken functionality.

This is one of a series of posts that explain Ably’s four pillars of dependability. The four pillars project at Ably is about making concrete, objectively verifiable, statements about the technical characteristics of the service. We aim to ensure that our claims about service performance are expressed clearly in terms of explicit metrics, and we explain in technical terms how those performance levels are met.

This year, Apple Intelligence will be available in beta.

You can read more about the possibilities our CEO believes it will unlock here.

In the digital age, we interact with countless applications, whether for personal, professional, or recreational purposes. Many of these applications appear consumer-oriented but are, in fact, business-to-business (B2B) applications. For example, when accessing healthcare services, payroll systems, or school management platforms, you are likely using applications where your provider (such as your GP or employer) is a business customer of a larger B2B application.
