Non-technical business founders often overestimate their value in tech startups and struggle to find technical co-founders because they lack the skills to execute their ideas. While ideas are important, execution, primarily driven by technical expertise in the early stages, holds greater value. Business founders can become valuable by focusing on their strengths: customer acquisition, relationship building, and their ability to create a significant customer base or get strategic partnerships.
Software teams often follow outdated and unnecessary practices without questioning their purpose. These practices in software engineering, such as limiting line width or adhering to outdated team rules, can slow down teams for no good reason. Instead, devs should ask clarifying questions, suggest alternatives, and test the relevance of existing processes.
A team won an Italian startup weekend competition. In this post, they talk about what they learned, such as the importance of validating a real-world problem by talking to potential users. Their solution to the problem was also reasoned well, with their pitch deck being clear, clean, and concise.

Devs can build ultra-fast websites by focusing on user journey metrics like server response, rendering, and interaction speed. Using Next.js features such as pre-rendering, caching, and React Server Components can help optimize performance. Each technique adds up to a smoother overall user experience over time.
This post discusses a class of React components that attempt to mix server-only and client-only logic, such as reading a file from the filesystem (server-side) while handling user input (client-side). Such components are “impossible” in traditional React rendering models. This tension illustrates the need for clear boundaries between server and client responsibilities.

A 20-year-old bug in GTA San Andreas that causes the Skimmer plane to disappear in-game has surfaced in Windows 11 24H2. The root cause has been traced to missing wheel scale parameters in the vehicles.ide file for the Skimmer, which went unnoticed due to the game's incomplete data validation. The bug was triggered by changes in Windows 11 24H2's internal stack management, which overwrote uninitialized values that the game unintentionally relied upon.
2025.04.24·cookieplmonster.github.io·14 min read·TLDR Web Dev Model Context Protocols (MCPs) are standardized APIs connecting external data sources and applications to LLMs. The current user experience and security of MCPs are not good enough yet for widespread adoption. The power will be with client-side interfaces like ChatGPT and Claude, who control which MCPs are used and how their responses are displayed. LLM providers will act as gatekeepers, managing MCP selection and monetization similar to app stores and search engines.

A whistleblower at the NLRB alleges that Elon Musk's DOGE accessed sensitive NLRB case files and downloaded code libraries, including one very similar to a program by DOGE employee Marko Elez. The code, designed for generating pseudo-infinite IPs, could be used for web scraping and brute force attacks. The DOGE accounts had unrestricted permissions to read, copy, and alter information. The code found supports the NLRB whistleblower's claim.
Rust can improve software safety by preventing vulnerabilities. The NAME:WRECK vulnerability in the Nucleus real-time operating system is a good case study. An experiment was conducted where engineers rewrote a vulnerable DNS decoding routine in Rust to show how Rust's memory safety and expressive language reduced the likelihood of introducing vulnerabilities. Rust implementations avoided arbitrary code execution vulnerabilities and resulted in recoverable errors, saving time and money compared to a secure C implementation.

LaunchDarkly cures your deployment anxiety by decoupling feature releases from code deployments. It goes beyond basic feature flags to unify release management, context-aware targeting, and experimentation [4] in one system.
React Router v7.5 introduces a new granular lazy loading API for routes in Data Mode that allows individual route properties—like loader, Component, and middleware—to be lazy-loaded separately. This change was driven by the need to support middleware without degrading performance. Unlike the previous route.lazy() function that loaded everything at once, the new approach allows for faster, more efficient loading by only fetching what's needed at each navigation step.
This developer created a text-based 3D Doom clone in the browser using DuckDB-WASM to handle game state and rendering with SQL queries. The core of the rendering engine is a SQL VIEW that performs raycasting via recursive CTEs, with JavaScript handling orchestration, sprite rendering, and Z-buffering. There were some challenges along the way with WASM initialization, SQL dialect differences, query planner limitations, and race conditions, all of which the dev overcame with some creativity.
Layered React Structure (LRS) is a method for organizing React projects for better clarity, modularity, and scalability. Unlike Angular's opinionated structure, React doesn't have a formal style guide, which often leads to inconsistent project layouts. LRS solves this by separating concerns into clearly defined layers: “smart” components (business logic) and “dumb” components (UI only), along with organized folders for views, components, hooks, services, utils, and types.
This post goes over 13 software engineering laws relevant to engineers and managers using comics and explanations. Each law is presented with its potential impact on engineering management. The laws range from well-known principles like Parkinson's Law (work expands to fill the time available for its completion) to lesser-known ones such as Zawinski's Law (every program attempts to expand until it can read mail - those programs which cannot expand are replaced by ones which can).
