davidbarker··on Show HN: TitleArt – Make text like it's 1997
Gosh, I hadn't thought about that for a long time. That was fun.
davidbarker··on Show HN: TitleArt – Make text like it's 1997
I immediately think of the hot air balloon.

I've just added support and it seems to work in the testing I've done. If you find anything that's off, feel free to let me know. Have fun!

Do you have any notes/write-up on that? I'd love to read.
davidbarker··on Show HN: TitleArt – Make text like it's 1997
Wonderful.

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).

davidbarker··on Show HN: TitleArt – Make text like it's 1997
I wanted to make a faithful recreation of the original WordArt so I went through the various screenshots I could find and tweaked the built-in styles by eye. It's pretty fun to play with, and I didn't realise it would take me back to sitting in the ICT computer rooms at my school in the late '90s.

Enjoy!

And please feel free to share anything you make with me — I'd love to see. (Contact details in the help menu.)

davidbarker··on Ask HN: Who wants to be hired? (October 2026)

  Location: London, UK
  Remote: Yes
  Willing to relocate: No
  Technologies: TypeScript/React, PHP/Laravel, PostgreSQL, React Native/Expo, product design/UX, AI-assisted development
  Résumé/CV: https://dvy.io
  Email: hn@davidbarker.me
  LinkedIn: https://www.linkedin.com/in/dvyio
  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.

This is pleasant coincidence. Really like your site and it's queued to send in my newsletter in the morning! Just happened to see your comment here while I was reading. Great work.

davidbarker··on Ask HN: What are you working on? (June 2026)
I have no practical use for this but I want to play with it anyway. Looks cool.
davidbarker··on Ask HN: What are you working on? (June 2026)
Typically one email per story.

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.

davidbarker··on Ask HN: What are you working on? (June 2026)
Currently working on HN Alerts — a simple free site I made to alert me (via email) to trending stories on Hacker News.

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.)

davidbarker··on Stop selling “unlimited”, when you mean “until we change our minds”
No, it's never promised unlimited — it's always had usage limits: 20× the usage of their regular Pro plan, with a limit of 50 sessions per month (a session being a 5-hour window), although I don't know if they ever enforced this.

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.

  Email: david@davidbarker.me
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/)

davidbarker··on OpenAI's o1-pro now available via API
That's right. I made a VS Code extension to combine all the files I have open into one long string I can copy & paste.

https://marketplace.visualstudio.com/items?itemName=DVYIO.co...

davidbarker··on OpenAI's o1-pro now available via API
Typically something like:

  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.
davidbarker··on OpenAI's o1-pro now available via API
Pricing: $150 / 1M input tokens, $600 / 1M output tokens. (Not a typo.)

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.)

davidbarker··on New tools for building agents
In theory there shouldn't be — LLMs are pretty robust to typos and usually infer the intended meaning regardless.

davidbarker··on Claude 3.7 Sonnet and Claude Code
Claude 3.5 Sonnet is great, but on a few occasions I've gone round in circles on a bug. I gave it to o1 pro and it fixed it in one shot.

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.

davidbarker··on Claude 3.7 Sonnet and Claude Code
If you do `/cost` it will tell you how much you've spent during that session so far.
davidbarker··on Show HN: Transform your codebase into a single Markdown doc for feeding into AI
If it's useful to anyone, I made a VS Code/Cursor extension that combines all open files into one big text document.

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

davidbarker··on Tesla's Robotaxi event still not started after 40 minutes [video]
It disappoints me when otherwise intelligent people take him for his word at this point. Even ignoring his descent into political madness and conspiracy, he's simply not trustworthy.

Fool me once, shame on Elon. Fool me 194 times, shame on me.

davidbarker··on FLUX1.1 [pro] – New SotA text-to-image model from Black Forest Labs
Unfortunately, not Flux. They're from Midjourney, using a few Degas as a style reference.

Whatever they're doing at Midjourney is still impressive. No training needed and a better result.

davidbarker··on FLUX1.1 [pro] – New SotA text-to-image model from Black Forest Labs
It's funny you should ask. I recently released a plugin (https://community-en.eagle.cool/plugin/4B56113D-EB3E-4020-A8...) for Eagle (an asset library management app) that allows you to write rules to caption/tag images and videos using various AI models.

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.
