I never thought of that, actually. Perhaps I should as I don't remember shimmer or sparkle. I'll see if I can find some examples (if you happen to know of any I can reference please send them over).
Enjoy!
And please feel free to share anything you make with me — I'd love to see. (Contact details in the help menu.)

Seeking: Senior Product Engineer with product design ownership (permanent preferred; open to substantial contract work)
I turn unclear product problems into useful, well-designed software. I talk to customers, turn what I learn into product and technical specs, design the workflows and interface, build the system, then help launch, market, and support it. That breadth is my strongest skill: it keeps the customer problem in view throughout.At Flowstate, I took a workforce-planning SaaS from blank repo to paid pilot in 10 weeks as sole engineer-designer. I've since owned product design, backend, mobile apps, Stripe Connect payments, AI-assisted listing tools, and infrastructure for a US trading-card marketplace.
I use and evaluate new AI models and coding workflows to make product development faster, while preserving quality through type safety, tests, CI, review, and product judgement.
I'm looking for a team that uses AI coding tools seriously, values strong product design, and keeps product builders close to customers.

It checks every 5 minutes, and if more than one story happens to meet the criteria during that 5 minute bucket then it'll put them into one email (so the "hiring" checks appear in one email). But in reality because it's rare that 2 stories will trend within the same 5 minute bucket it ends up being one email per story.
It sends me an email once a story hits a certain number of upvotes per minute, so it's useful for keeping track of breaking news.
It'll also soon allow you to get alerted to specific words or phrases in titles. (I have one set up so the monthly hiring threads notify me as soon as they appear.)
They appear to have removed reference to this 50-session cap in their usage documents. (https://gist.github.com/eonist/5ac2fd483cf91a6e6e5ef33cfbd1e...)
So even if these mystery people Anthropic reference who did run it "in the background, 24/7", they still would've had to stay within usage limits.

I'm a multidisciplinary designer-developer with deep curiosity and a passion for building intuitive, human-centered products, particularly those leveraging generative AI.My professional roles have typically involved much more than just coding, spanning product design, strategy, marketing, and customer support. I thrive in small, ambitious teams where I can make a tangible impact.
Outside of work, I've built successful side projects, including:
- Balance, a free web app that anonymously helps people with acute anxiety (https://balance.dvy.io/)
- AI Autotagger, an Eagle plugin currently processing over a million images and videos per month (https://community-en.eagle.cool/plugin/4B56113D-EB3E-4020-A8...)
- HN Alerts, a free notification service that sends emails when trending Hacker News stories appear (https://hnalerts.com/)

Look carefully through my codebase and identify any bugs/issues, or refactors that could improve it.
<codebase>
…
</codebase>
Doesn't have to be anything overly complicated to get good results. It also does well if you give it a git diff.Very expensive, but I've been using it with my ChatGPT Pro subscription and it's remarkably capable. I'll give it 100,000 token codebases and it'll find nuanced bugs I completely overlooked.
(Now I almost feel bad considering the API price vs. the price I pay for the subscription.)

More generally, I tend to give o1 pro as much of my codebase as possible (it can take around 100k tokens) and then ask it for small chunks of work which I then pass to Sonnet inside Cursor.
Very excited to see what o3 pro can do.
I use it with ChatGPT's o1 pro (which can handle around 100,000 tokens).
1. Open all of the files I think are relevant
2. Use the extension to combine them
3. Copy and paste into ChatGPT

Fool me once, shame on Elon. Fool me 194 times, shame on me.
Whatever they're doing at Midjourney is still impressive. No training needed and a better result.
I have a preset in there that I sometimes use to generate captions using GPT-4o.
If you use Replicate, they'll also generate captions for you automatically if you wish. (I think they use LLaVA behind the scenes.) I typically use this just because it's easier, and seems to work well enough.
