<strong>MCP is dead. Long live the CLI (5 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
MCPs can be replaced by CLIs (command line interfaces) most of the time. This is because CLIs are composable and debuggable for both humans and LLMs, and they often don't require any extra background processes. As a result, CLIs should be preferred over MCPs in most cases.

<strong>Creating Query Abstractions (8 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Custom hooks are the wrong way to abstract useQuery, as they lock you into one hook, get messy with TypeScript generics, and can't be used outside components. Instead, use queryOptions to define your key and fetch function once, then spread it into whatever hook you need (useQuery, useSuspenseQuery, etc.) with per-usage options on top.

<strong>747s and Coding Agents (6 minute read)</strong>

A 747 pilot who wistfully noted that his highly skilled job offered no further opportunities for improvement or learning. The advent of AI coding agents makes programming feel somewhat familiar in cases of the nitty-gritty of code, as they reduce the need for deep understanding of underlying code.

<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Computer programming is still a valuable career despite the advent of AI, as the core skills of problem-solving and complexity control will always be essential. Junior programmers should still actively write code rather than rely solely on AI generation, as this hands-on experience is necessary for developing a deep understanding.

<strong>"All Lawful Use": Much More Than You Wanted To Know (16 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
US Secretary of War Pete Hegseth designated AI company Anthropic a "supply chain risk" for refusing military use of its AIs for surveillance and autonomous weapons, then quickly made a similar deal with OpenAI. However, OpenAI's stated safeguards have been criticized by many as they are not as transparent in their language compared to Anthropic.

<strong>Claude Adds Ability to Import Memory From Other AI Providers (2 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Anthropic has launched a new memory import tool for Claude, allowing users to transfer their accumulated context and preferences from other AI providers like ChatGPT or Gemini. The process is simple: users paste a special prompt into their current AI, copy the output, and then paste it into Claude's memory settings. This easy transferability suggests there's still no good lock-in or moat in the LLM industry.
