REACT TRENDS IN 2025

A major trend in 2025 is the increasing adoption of React Server Components (RSC) as a standard and React Server Functions (RSF), which simplify data fetching and mutations in both Server and Client components. React is going through UI standardization through libraries like Shadcn UI and tooling streamlining with tools like Biome.

THE WORST PROGRAMMER I KNOW

Developer productivity metrics like lines of code are not always accurate for engineers. Since many engineers often spend more time architecting designs and mentoring others, this leads to lower lines of code output. However, these types of engineers generally cause the team overall to output more lines of code, so these metrics might be better as a team-wide metric rather than an individual one.

CAREER DEVELOPMENT: WHAT IT REALLY MEANS TO BE A MANAGER, DIRECTOR, OR VP

Typical corporate "leveling" systems are often arbitrary. Instead, a proposed simplified management hierarchy consists of three meaningful levels: manager, director, and vice president. Managers execute plans with support, directors drive results independently, and VPs are responsible for creating and owning the plan. VPs, unlike directors, are ultimately accountable for the results of their plans and cannot hide behind prior approval if the plan fails.

DON'T BE AFRAID OF TYPES

There's a common aversion to creating new data types in codebases, which comes from a fear of altering the "grand design." However, creating new types to group related values, even for specific functions, makes code simpler and much easier to read. Devs should create types whenever necessary.

THE SOFTWARE ENGINEERING IDENTITY CRISIS

The rise of AI coding assistants is causing an identity crisis for software engineers, who are shifting from hands-on builders to orchestrators of AI-generated code. This transition challenges the core satisfaction engineers get from creating solutions and mastering technical skills. For devs to adapt to this change, they should balance deep technical work with strategic AI orchestration.

PYTORCH INTERNALS

This is a guide to the inner workings of the PyTorch library. It is structured in two parts: (1) a conceptual overview of tensor libraries, including data types, extension points, and automatic differentiation; and (2) practical coding aspects with guidance on navigating the codebase, kernel writing, and optimizing the development workflow.

USE LONG OPTIONS IN SCRIPTS

For better readability and maintainability, always use long-form options (e.g., `--create`) instead of short-form options (e.g., `-c`) when writing scripts that use command-line utilities.

YOU DON'T KNOW EVERYTHING, AND THAT IS OKAY

It's okay to not know everything as a dev - instead, focus on problem-solving, use your network, and always keep learning.
