Welcome, Developers! đź‘‹

We are seeing interesting timelines with AI: one developer juggles 15 browser tabs for free AI models, another restructures his sleep for Claude limits, while thousands protested OpenAI's GPT-4o removal.


Also, dive into why live coding interviews are fundamentally broken, guides on parsing PDFs and reviewing code and more.

Live Coding Tests Suck

Live coding interviews don't actually test coding ability, they measure cortisol levels under stress. The engineer who freezes during a 30-minute LeetCode exercise might be the same person who ships flawless code and debugs complex systems daily. Most jobs don't require performing while being watched and judged which makes live coding a flawed metric for interviews.

GPT-4o Removal Sparks Outrage
Despite there being so many better models over GPT-4o, we forget that it was the default model in ChatGPT for quite some time now to the point that it has a loyal userbase that weren't happy with its removal.


While some people were glad about its removal due to its people-pleasing tendencies, others felt the newer models lack creativity and feel like a "tool". Sam Altman eventually agreed to roll back the model to monitor its usage.

How I Code with AI on a Budget/Free

For those on a budget and don't mind their data being used for training, the free tiers for AI agents are worth considering. Tom maintains 15+ browser tabs with free tiers of models like GLM 4.5, Kimi K2, and Gemini 2.5 Pro, creating a diverse "AI buffet" for different coding perspectives.


Besides the budget talk, he feels that web-based AI chats significantly outperform coding agents like Cursor due to cleaner context without tool-related noise. Plus, this is a great way to identify which model is best for which task.

Optimizing my sleep around Claude usage limits

During productive sessions for his SaaS, Matt would consistently hit the Claude Pro limits, breaking his flow. Inspired by sailors' power-napping, he figured why not try sleeping around the 5-hour Claude reset? The results show better developer flow so far, but it's surely a unique process of achieving it.

How to Review Code

Mathias, a well-known developer in the Rust community, has written a detailed piece on his learnings over the year about reviewing code. Insights include looking at the bigger picture, naming emphasis, open communication, actionable feedback, and learning to say no when quality is not up to standards.
