> There is an endless list of problems to solve

As an indie hacker I often struggle to find new ideas. Are there any practical strategies for discovering these real pain points?

When I saw that the trail goes through just one word like "Us/Them", "fictions" I thought it might be more useful if the trail went through concepts.

I like the idea, but this is going be a very very long journey to develop a completely new machine-friendly language like this while LLMs still have many limitations now.

I built a website (https://hpyhn.xyz) for hacker news users for reasons: 1. hn comments are valuable, I've spent a lot of time going through hn comments. I think there are valuable comments buried in the threads with fewer points, so it's not enough to just read top3 threads.

2. Sometimes a good post is ignored due to a bad title, sometimes I still have no idea what the post's theme even after I read a few paragraphs.

3. I want to filter out some posts I'm not interested in, but I realized I need read some other posts it's not a simple yes/no problem, so I gave every post a interesting score based on my own preference

so I built this tool to save my time while not missing out too much on hn

Thanks for feedback! It's working now.

Any questions we could chat on X @liqilin3

Wow this is so rare, I can't recall any case like this.

But there are celebrities with exactly the same name, the media add a "big" or "little" prefix to their names according to age

> How do Chinese people deal with name conflicts?

In a big company, there are often many people with the same name. some companies may add a numeric suffix to their name like abc1, abc2, abc3.

We usually don't use our real names for social media accounts

> Brittle performance – A model might do well on short, primary school-style maths questions, but if you change the numbers or wording slightly, it suddenly fails. This shows it may be memorising patterns rather than truly understanding the problem

This finding really shocked me

Thanks for sharing. There are two things I don't understand:

> XDP for Egress Traffic Flow Diagram

1. Are packages still raw application data when they get to veth0-A without going through the tcp-stack?

2. In container to container communication case, do you plan redirect packages directly from veth0-A to veth0-B

Sounds very practical in real-world use cases. I trained a ML model couple months ago, I think it's a good case to test this product.

Yeah, the danger lies not in AI itself, but in inexperienced users treating it as a magic solution.

I have to praise the interactive style of this content.

As a C/C++ dev, I've always thought assembly was much harder. But this interactive content makes assembly clearer.

Maybe there are too many requests, so they have to offload the videos to s3.

Yeah, it's kind of annoying to fix these bugs for me, even though GDB is a great debugging tool.

I always wonder if there are any techniques to avoid these kind of bugs in huge projects like OSes and browsers, otherwise it can be a nightmare

One of the biggest headaches for me is memory bugs when codebase grows large. So I 'm very interested: is this a headache for you too and how do you deal with this?
