You can run your entire life through Claude Code thanks to MCP, Skills, and Subagents

I’m going to need a new tab key
Replying to @claudeai
Claude will now automatically suggest your next prompt. After a task finishes, Claude will occasionally show a followup suggestion in ghost text. Press Enter to send it or Tab to prefill your next prompt.

It feels like software engineering is cooked when you’re already a proficient engineer. Then you watch non-technical people vibe code something and realize you’ll be just fine. Yeah the bar is higher - but that’s literally all of the history of technology.
Experience no longer really matters in software engineering. Opus 4.5 basically levelled the playing field. Jesus - 10 years of my life were for nothing

Anthropic's prompt structure guide is great.

Don’t believe anyone that says you can just clone an app like MacroFactor and make $20k a month easily. These apps aren’t easy to clone. Sure you can vibe code the basic stuff in a weekend, but the real value is in the details, which takes much longer and is much harder.

Anyone fine tuning models is wasting their time. GPT-6 will beat you, Claude-5 will beat you, Gemini-3 will beat you, Grok-5 will beat you, Llama-5.

One of the funnier @grok interactions I've seen on here. This is a case to keep grok, please

I want to know what they were doing that they were using Claude Code 24/7 for WEEKS!
Replying to @AnthropicAI
Some of the biggest Claude Code fans are running it continuously in the background, 24/7. These uses are remarkable and we want to enable them. But a few outlying cases are very costly to support. For example, one user consumed tens of thousands in model usage on a $200 plan.

Big-O for beginners: Imagine we have a stack of 100 sticky notes. On the back of each note, there is a name written down.

If I want to compare each of the 100 notes against each other, that is comparing 100 notes, 100 times, which makes it a quadratic time operation, O(n^2).

Big O is an important topic in technical interviews. Simplifying it to analogies will help you visualize and understand tech concepts easier!

the only difference between me (experienced swe) and the interns that I've had was confidence i just focused all of my time instilling confidence in them. if they just pretended like they were experienced they'd have just as much impact
