DOES INTERACTION TO NEXT PAINT ACTUALLY CORRELATE TO USER BEHAVIOR?

Earlier this year, Google announced that INP (Interaction to Next Paint) is going out of experimental mode and will replace First Input Delay (FID) as a Core Web Vital in April 2024. This post takes real world data to attempt to correlate INP with real user behavior and business metrics. The short conclusion is that as INP gets worse, business metrics, like conversion rates for sales, tend to suffer.

A DEEP DIVE INTO CPU REQUESTS AND LIMITS IN KUBERNETES

This article explores the effects of CPU requests and limits in Kubernetes and the differences between the default CPU Manager policy and the static policy. To demonstrate these concepts, the article uses scenarios where setting CPU limits is advisable, such as benchmarking, multi-tenant environments, predictability, and Quality of Service (QoS) guarantees. It delves into the details of the CPU Manager's static policy, including how it assigns CPU cores to containers and the associated metrics to monitor.

YOU ARE NEVER TAUGHT HOW TO BUILD QUALITY SOFTWARE

It’s common for software projects to lack adequate quality assurance measures, leading to last-minute QA sprints and unreliable software releases. Budget constraints frequently lead companies to cut QA efforts, resulting in rushed and error-prone releases. In order to convince management of the importance of QA, it’s important to frame it in terms of cost savings and efficiency gains and start with a minimal effective dose of QA measures.

WHAT I WISH I KNEW AS A MID-LEVEL ENGINEER

Shortly after being promoted to mid-level engineer, this author made a subtle mistake by focusing on tasks that, while technically impressive, didn't align with the company's priorities for senior-level engineers. He received an "exceeds expectations" rating but didn’t make progress towards a promotion. To progress from mid-level to senior, it's crucial to consider the "why" behind your work and ensure it aligns with what's most important to your personal interests, team, and company all at once.

BECOMING A GO-TO PERSON GETS YOU PROMOTED. HERE'S HOW TO DO IT AS A SOFTWARE ENGINEER

One effective strategy to reach the senior level as an engineer is to become an expert in a specific area, whether it's a technical skill or a product domain. To determine your expertise, consider what aligns with team or company impact, what you're good at, and what you're passionate about. To become known as an expert, focus on being visible and adding value, such as giving presentations, leading projects, solving challenging problems, and actively contributing to your team's success.

HOW OFTEN SHOULD WE SHARPEN OUR TOOLS?

Tool sharpening refers to the process of improving or upgrading the tools and software one uses for work. This author shares a personal experience of transitioning from one text editor (NEdit) to another (Vim) and later to Neovim, highlighting the considerations, challenges, and benefits of such transitions. As engineers, there is a cost of time and effort in adopting new tools. At the same time, it’s important to periodically reevaluate tool choices and configurations to ensure they enable one to be as productive as possible.

AN INTUITIVE DOCUMENTATION STRATEGY

Good documentation enables smoother project handovers, reduces dependencies on core team members, and simplifies onboarding for new team members. This is a playbook for creating intuitive documentation, including the importance of creating a simple manifesto or vision, establishing an intuitive folder structure, and automating documentation creation where it adds value. It includes practical examples and templates for organizing documentation, covering topics like architecture, onboarding guides, and specialist path guides.
