Teams need alerting and incident management tools to respond to incidents – but today, they’re separate. What's more, the way we build software continues to evolve and become more complex, but alerting tools are still stuck in the past. Introducing Signals by FireHydrant [5] a modern alerting tool that helps you:
This article discusses the process of writing a code generator for a systems programming language with a focus on translating a high-level language into x86-64 assembly code. It explains how to represent integer literals, variables, negation, and addition in the compiler and provides code examples for each.
The activity feed team at Postman investigated their DocumentDB usage and was able to reduce the monthly cost from $6k to $3k with 50% performance gains. They optimized their feed collation query, refined their indexing strategy, shifted from TTL-based deletes to direct deletes, and updated their collation strategy to use updates instead of inserts and deletes. These changes led to significant reductions in both read and write I/O operations and a 35% reduction in CPU utilization.
This article explores React Server Components and React Server Actions, clarifying key terms and concepts related to these features and highlighting the experimental and under-documented nature of these APIs. It shows how both can be used to address various challenges in web development, such as data fetching, routing, latency, and more. The article uses an example of migrating a React Notes App to React Server Components without using a framework, showcasing the use of React Canary, React Server & React Flight APIs, and other dependencies.
In large organizations, there is a tendency to focus on technical minutiae and overcomplicate solutions rather than addressing core business problems. There are two types of companies: the ones that prioritize measurable business outcomes but accumulate technical debt, and those that obsess over technical details and tools without considering the business impact. Finding a middle ground where developers can focus on core business logic without unnecessary complexity is essential.
It's crucial to be aware of survivorship bias when seeking advice in the tech industry as individuals tend to believe their path is the only path to success. The job market is constantly changing and what worked in the past may not work today. Your experience will also vary depending on factors like location and educational background.

Hotkey allows the triggering of actions on target elements when specific keys or key combinations are pressed on the keyboard. These hotkeys can be scoped to form fields and are extracted from a target element's data-hotkey attribute by default. GitHub uses hotkeys extensively to declare shortcuts on its platform.
A recent experiment showed that GPT-4 is not well-calibrated in predicting the probability of various events and questions, often overestimating or underestimating probabilities. It also shows variations in prediction quality across different categories, with better performance in some areas like sports, and poorer performance in others like personal questions. This suggests that GPT-4's performance variations are not solely due to question difficulty but also reflect differences in its ability to provide confident and well-calibrated predictions across categories.
Web Components that work in any framework consist of three key technologies: Custom Elements, Shadow DOM, and HTML Templates. Custom Elements allow you to define your own custom HTML elements that can be reused across your site and even published for use by other developers. Shadow DOM provides encapsulation, ensuring that the styles and behavior of your custom elements are not affected by global styles. HTML Templates allow you to create reusable templates for rendering content within your web components. While building web components can involve some boilerplate code, there are tools like Lit that simplify the process, making it more streamlined and ergonomic.
Chrome introduced Core Web Vitals (CWV) in 2020 to measure web performance. Today, over 40% of sites pass all of the CWV metrics, resulting in pages that load and respond to interactions more quickly.
API latency refers to the time it takes for a request to travel from the client to the server, get processed on the server, and then return a response back to the client. API response time encompasses the entire time it takes for a client to send a request to an API, the server to process that request, and for the server to send a complete response back to the client.
