My experience with the current tools so far: 1. It helps to get me going with new languages, frameworks, utilities or full green field stuff. After that I expend a lot of time parsing the code to understand what it wrote that I kind of "trust" it because it is too tedious but "it works". 2.

I'm not a programmer, but I need to write python and bash programs to do my work. I also have a few websites and other personal projects. Claude Code helps me implement those little projects I've been wanting to do for a very long time, but I couldn't due to the lack of coding experience and time. Now I'm doing them. Also now I can improve my emacs environment, because I can create lisp functions with ease. For me, t…

Big +1 to customizing emacs! Used to feel so out of reach, but now I basically rolled my own cursor.

Before this they supposedly had a longer context window than ChatGPT, but I have workloads that abuse the heck out of context windows (100-120K tokens). ChatGPT genuinely seems to have a 32K context window, in the sense that is legitimately remembers/can utilize everything within that window. Claude previously had "200K" context windows, but during testing it wouldn't even hit a full 32K before hitting a wall/it forg…

Strong agree, Claude is very quick to forget things like "don't do this", "never do this" or things it tried that were wrong. It will happily keep looping even in very short conversations, completely defeating the purpose of using it. It's easy to game the numbers, but it falls apart in the real world.

I've found it better to use antonyms than negations most situations.

LLMs totally kick ass for making bash scripts

I believe this can be configured in Claude Code via the following environment variable: ANTHROPIC_BETAS="context-1m-2025-08-07" claude

Have you tested it? I see that this env var isn't specified in their docs https://docs.anthropic.com/en/docs/claude-code/settings#envi...

    Add these settings to your `.claude/settings.json`:

     ```json
     {
       "env": {
         "ANTHROPIC_CUSTOM_HEADERS": {"anthropic-beta":
     "context-1m-2025-08-07"},
         "ANTHROPIC_MODEL": "claude-sonnet-4-20250514",
         "CLAUDE_CODE_MAX_OUTPUT_TOKENS": 8192
       }
     }
     ```

I'm not sure if I would say human reasoning is 'probabilistic' unless you are taking a very far step back and saying based on how the person lived, they have ingrained biases (weights) that dictates how they reason. I don't know if LLMs have a built in scepticism like humans do, that plays a significant role in reasoning. Regardless if you believe LLMs are probabilistic or not, I think what we are both saying is cont…

Humans have a neuro-chemical system that performs operations with electrical signals. That's the level to look at, unless you have a dualist view of the brain (we are channeling a super-natural forces).

Complexity theory doesn’t have a mathematics (yet), but that doesn’t mean we can’t see that it exists. Studying the brain at the lowest levels haven’t lead to any major insights in how cognition functions.

I work in FAANG, have been for over a decade. These tools are creating a huge amount of value, starting with Copilot but now with tools like Claude Code and Cursor. The people doing so don’t have a lot of time to comment about it on HN since we’re busy building things.

> These tools are creating a huge amount of value... > The people doing so don’t have a lot of time to comment about it on HN since we’re busy building… “We’re so much more productive that we don’t have time to tell you how much more productive we are” Do you see how that sounds?

I feel this, honestly. I get so much more work done (currently: building & shipping games, maintaining websites, managing APIs, releasing several mobile apps, and developing native desktop applications) managing 5x claude instances that the majority of my time is sucked up by just prompting whichever agent is done on their next task(s), and there's a real feeling of lost productivity if any agent is left idle for too long.

The only time to browse HN left is when all the agents are comfortably spinning away.

At the end of the day, all tools are made to make their users' lives easier.

I use GitHub Copilot. I recently did a vibe code hobby project for a command line tool that can display my computer's IP, hard drive, hard drive space, CPU, etc. GPT 4.1 did coding and Claude did the bug fixing.

The code it wrote worked, and I even asked it to create a PowerShell script to build the project for release

It is very useful for small tasks like fixing network problems, or writing regexp patterns based on a few examples.

Maybe that is a skills issue.

If you are suggesting that LLMs are proving quite good at taking over the low skilled work that probably 90% of devs spend the majority of their time doing, I totally agree. It is the simplest explanation for why many people think they are magic, while some people find very little value. On the occasion that I find myself having to write web code for whatever reason, I'm very happy to have Claude. I don't enjoy codin…

What a supremely arrogant comment.

I have yet to get it to generate code past 10ish lines that I am willing to accept. I read stuff like this and wonder how low yall's standards are, or if you are working on projects that just do not matter in any real world sense.

4/5 times I can easily get 100s of lines output, that only needs a quick once over. 1/5 times, I spend an extra hour tangled in code it outputs that I eventually just rewrite from scratch. Definitely a massive net positive, but that 20% is extremely frustrating.

In my experience, if I have to issue more than 2 corrections, I'm better off restarting and beefing up the prompt or just doing it myself
