Show HN: ChaosData – Chaotic data that fits your schema

blamarvt — Thu, 01 Oct 2026 14:19:23 +0000

I've always been the person who types an emoji into a form just to see what happens. Most of the bugs I've reported are really about data that my code assumed would look a certain way.

So I built ChaosData. Give it a schema, and it generates realistic data with a few deliberate edge cases mixed in. Emojis where they shouldn't be, malformed strings, edge-case integers, etc.

  mysqldump --no-data shop | curl -s -X POST \
    "https://chaosdata.net/api/v1/quick-generate?rows=100&chaos=20" \
    -H "Accept: text/sql" --data-binary @- | mysql shop_test

Some tools generate realisitc data, and some generate chaotic data, but we'll do both (and respect your schema)!

There are lots of ways I could go from here, but I wanted to see if I could get some input first before I took it further.

I'd love any thoughts or feedback.

I mean, lots of numbers are near zero depending on your definition of near.

This is not how software works. Although I guess this isn't quite as catchy:

Assume all software is broken at all times. Constantly try to ensure it works and is secure. Sometimes updates break things. Test before production. Ensure test environments are similar to production. You're going to break things.

I think that's great for you. Truly.

Could it be that your experience doesn't apply to everyone?

I've been living in the same area as you, and I go for walks almost daily; it's astonishingly miserable out.

I have a friend who does almost identical physical activity to me, as we have similar jobs. He sweats very little when outside unless physically exerting himself. I sweat profusely when just walking; even when wearing significantly less clothing.

Why do you think tailored content will prevent you from exploring new territory? You are choosing the content.

I can't wait to watch the first entirely generated short film and create my own.

Are you saying you don't see the value in video generation? The potential for unlimited high quality and customizable content generation?

> Don’t listen to me, I don’t know anything about drugs. Obviously you’ll build up a tolerance over time and obviously it’s very bad to depend on a substance to perform.

Cool.

As someone on the same dose of Adderall/Vyvanse for 15+ years it's really hard to keep reading after this. Lots of people depend on substances to live. This article reads like it's trying to solve all psychological conditions with willpower.

I choose to interpret the post as saying "start small, and be consistent". If you were to tell someone to go for an at least 30 minute walk every day many people would balk at you.

Start with a minute walk. Make time in your day for it. Extend to a 2 minute walk. 5 minute. 15 minute. Etc.

What if the first blind person was also deaf and just trolling the other blind person so wouldn't the second "Can you hear me?" be needed?

It's pretty hard for me to get past the very first sentence.

Technology isn't supposed to do anything. Technology is a tool to be used. Anyone can use tools incorrectly. Lots of people do, including myself!

> Why would anyone put lots of people on a product that is mature and doesn't need a lot of work?

Nobody is suggesting anyone put 'lots of people' on a mature product. However, there are always things that need to be done.

Apps need to be updated for new devices, OS/library/security updates, and general bug reports to name a few. That's just on the app side, the same is true for any build pipelines/hosting infrastructure.

These apps don't run themselves regardless of how mature they are.

You're right in that fewer people are needed and I'm all for optimizing but what I feel like you're missing is that it's quite easy to over-optimize for cost at the expense of users.

Ask HN: Standard for webhook source IP declaration?

blamarvt — Tue, 22 Aug 2023 18:50:32 +0000

Is there a standard way to tell customers where your webhooks will be coming from just in case they want to whitelist those IPs?

If there isn't a standard what is the most common way? Docs? Some random URL with IP CIDRs in JSON?

“Not bullish” implies either neutral or bearish, I think.
