As a burnt-out, laid-off aging developer, I want to thank Anthropic for helping me get in love with programming again. Claude Code on terminal with all my beloved *nix tools and vim rocks.

Agreed, it's actually fun again. The evening hours I used to burn with video games and weed are now spent with claude code, rewriting and finishing up all my custom desktop tools and utilities I started years ago.

I had ChatGPT write from spec an assignment I failed to complete during university, that has always stuck with me as something I would like to finish.

> IMPORTANT: DO NOT ADD * ANY** COMMENTS unless asked* Interesting. This was in the old 1.x prompt, removed for 2.0. But CC would pretty much always add comments in 1.x, something I would never request, and would often have to tell it to stop doing (and it would still do it sometimes even after being told to stop).

I am guessing this is an attempt to save computing resources/tokens?

Comments in code are instant technical debt. They need to be maintained alongside the code, so you are *programming" twice. Avoid comments, except when they really explain some obscure, incomprehensible section of code or to prevent explorers from the future getting smacked on the face twice by the same stick. I find myself using the latter often to tell future agents what not to do in the next few lines.

So tell us how to safely run this stuff then. I was under the impression that Docker container escapes are actually very rare. How high do you rate the chance of a prompt injection attack against Claude running in a docker container on macOS managing to break out of that container? (Actually hang on, you called me out for suggesting containers like Docker are safe but that's not what I said - I said "a safe container…

> So tell us how to safely run this stuff then. That's the secret, cap... you can't. And it's due to in band signalling, something I've mentioned on numerous occasions. People should entertain the idea that we're going to have to reeducated people about what is and isn't possible because the AI world has been playing make believe so much they can't see the fundamental problems to which there is no solution. https://e…

Seems pretty glib. Be more specific about what "can't" be done? The preceding argument was about the inadequacy of namespaced shared-kernel containers for workload isolation. But there are lots of ways to isolate workloads.

Cerebras has OpenAI compatible "Qwen Code" support. ~4000 tokens/s. Qwen code's 480B param model (MoE) that's quite good. Not quite sonnet good, but speed is amazing. https://www.cerebras.ai/blog/introducing-cerebras-code

When they announced this I went to try it and they only work with Cline really (which is what they promote there) but Cline has this VSCode dependency as far as I know and I don't really like that. I have my IDE flow and my CLI flow and I don't want to mix them. But you're right, they have an OpenAI compatible API https://inference-docs.cerebras.ai/resources/openai so perhaps I can actually use this in the CLI! Thank…

I'm using Cerebras's MCP with Claude Code and it works mostly OK. CC doesn't send updates through the MCP by default (as far as I can tell) so I have to add an instruction to CLAUDE.md to tell it to always send code creation and updates through the Cerebras MCP, which works pretty well.

You can rewind your context back to the checkpoint

That is nice, but it makes me wonder how little people actually know and use git nowadays. This is after all, something git really shines at. Still good to see! (It's not like I can't still just use git for that, which I fully intend to do)

If you're building a feature, you don’t want to commit every single line of code. Instead, you commit complete chunks of work. That’s why the ability to go back with Esc-Esc and revert code changes when Claude goes off the rails is a very welcome improvement.

imo, comments are quite good for junior developers. docstrings are much preferred though.

I really like these tools. Yesterday I gave it a filename for a video of my infant daughter eating which I took while I had my phone on the charger. The top of the charger slightly obscured the video. I told it to crop the video to just her and remove the obscured portion and that I had ffmpeg and imagemagick installed and it looked at the video, found the crop dimensions, then ran ffmpeg and I had a video of her all…

Isn't cropping a video something you can do in the photos app in 2 seconds?

Shift+Tab still brings up the planning mode.

What's the difference between thinking and planning? Planning leads to the use of the ToDoWrite Tool?

The thinking is more tokens dedicated to think. While planning has a different system prompt.

Amazing work, dang. Is there a way to report a comment to the mods? Or the flag feature does that already?
