Got fed up with Mac's built in audio transcriber and the lack of simple, free software to run OpenAI's whisper model locally.
So I built it with Claude Code in a day.
Free, local, speak words into your cursor position.
Sharing it with you guys so you can win with your voice.

Yes, please! No reason not to support ESM in 2026. Even jQuery can do it 😁
Woah. jQuery migrated to ESM!
Come on other big libraries! No excuses now.

jQuery support standard JS modules. jQuery!
If they can do it, other big libraries can do it too.

Been playing around with a personal AI assistant on my phone. Integrates with Notion, can talk to it, runs locally, etc. Open source to boot.

I want to give a shout out to my “useless” philosophy degree.
You taught me how to read and write.
You taught me how to think critically.
And you taught me how to argue constructively.
All of which I use extensively at work.

Opus 4.5 Fail of the Day
In a valiant attempt to fix the overflow issue in a modal, Opus took 5 tries at it and still failed to fix such a simple bug.
Genius architect, terrible stylist 😂

I’ve gained a new appreciation for content creators out there.
As a new startup founder, I’m learning how to use social media and started creating YouTube videos for software education.
This stuff is hard. Very hard.
Mad respect to you guys.

It's a great time to hire junior devs.
They're more creative with AI, bring energy to an organization, and are on a deep discount thanks to the industry.

Do you have a brag board?
A brag board is where you write down your accomplishments.
Big or small.
Great for performance reviews, salary negotiations, or even when you're burned out.
When you finish something, make sure to write it down.

Be wary of magic numbers.
- The next reader has no clue why a number is that number.
- It's super hard to find in the codebase / update in all places
Instead:
- Assign to a variable and give it a meaningful name.
- Hoisting to the top of the file or refactor to a config file.

Lesson #1 from Design of Everyday Things:
- affordances are a deeply misunderstood concept
- if your product has features but no signals for discovery, then you have a design problem

Stop worrying about using the best model.
The bottleneck isn't your model capability. It's your prompt.
Spend the extra minute or two curating your idea, or better yet, use the LLM to improve your prompt first.
Take the guesswork out for your AI and find your results improve 100%.

Ever console.log'ed the... console?
I use these methods all the time:
- console.time() - easy way to time function calls
- console.table() - easy way to view a list of objects
- console.error() - easy way to view errors
