liqilin1567··on Ask HN: Is it still worth pursuing a software startup?
> 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?

liqilin1567··on Show HN: I used Claude Code to discover connections between 100 books
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.
liqilin1567··on Nerd: A language for LLMs, not humans
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.
liqilin1567··on Ask HN: What Are You Working On? (December 2025)
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

liqilin1567··on Ask HN: What Are You Working On? (Nov 2025)
Thanks for feedback! It's working now.

Any questions we could chat on X @liqilin3

liqilin1567··on Ask HN: What Are You Working On? (Nov 2025)
I'm glad to hear feedback

liqilin1567··on I Am Mark Zuckerberg
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

liqilin1567··on I Am Mark Zuckerberg
> 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

liqilin1567··on Study identifies weaknesses in how AI systems are evaluated
> 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

liqilin1567··on An eBPF loophole: Using XDP for egress traffic
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

liqilin1567··on Launch HN: Plexe (YC X25) – Build production-grade ML models from prompts
> Each agent focuses on its domain: data analysis, feature engineering, model selection, deployment, and so on

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.

liqilin1567··on AI can code, but it can't build software
Every time I see a "build an app with just one English sentence" hype, I turn away immediately
liqilin1567··on Claude for Excel
Yeah, the danger lies not in AI itself, but in inexperienced users treating it as a magic solution.
liqilin1567··on Easy RISC-V
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.

liqilin1567··on Validating your ideas on strangers (2017)
This reminds me of a picture where a guy pitch someone in the restroom :D https://pbs.twimg.com/media/G3WSULNaAAAjE17.jpg
liqilin1567··on Feed the bots
Seems like these garbage pages can't trap bots. People discussed it in this thread: https://news.ycombinator.com/item?id=45711987
liqilin1567··on We saved $500k per year by rolling our own "S3"
Maybe there are too many requests, so they have to offload the videos to s3.
liqilin1567··on Show HN: MyraOS – My 32-bit operating system in C and ASM (Hack Club project)
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

liqilin1567··on Show HN: MyraOS – My 32-bit operating system in C and ASM (Hack Club project)
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?
liqilin1567··on An Update on TinyKVM
Exactly. Since containers share the same kernel with the host, if there is a kernel bug that can be exploited from within a container, it makes the whole host vulnerable.
liqilin1567··on The Journey Before main()
Yeah, even library loading relies on glibc, so we can't really escape glibc on GNU/Linux.
liqilin1567··on D2: Diagram Scripting Language
Thanks, animation is really an impressive feature.
liqilin1567··on D2: Diagram Scripting Language
I didn't know about D2. Mind sharing features that are better than mermaid?
liqilin1567··on An Update on TinyKVM
I got a question: in what scenarios is it vulnerable to use containers as a sandbox?
liqilin1567··on Why I code as a CTO
I agree. As a company grows, the CTO must shift from coder to leader, architect, and culture-shaper.
liqilin1567··on The Journey Before main()
Running a container is exactly my current solution as well.

Are there any other solutions that don't depend on glibc?

liqilin1567··on I'm drowning in AI features I never asked for and I hate it
I found that aws's chatbot isn't very good - I often can't get my questions answered with it
liqilin1567··on Show HN: Diagram as code tool with draggable customizations
Great project, I've been generating diagrams with llm for a while, and I often struggle to refine layout through the model.

But now I can interactively make changes to the diagram with this, it's very productive.

liqilin1567··on The Journey Before main()
I'm sick of glibc compatibility problems. Are there any recommended replacements?
