Today I tried vibe coding to build something useful - a modern Pomodoro app with customizable timers and themes. Instead of typing, I talked to Claude Sonnet 3.7 through GitHub Copilot using the macOS dictation app.
Here is the result - Pomodoro Flow app my-pomodoro-flow.netlify.app

Hilarious! AGI is almost here 😅!
Gift link, probably the funniest thing the Wall Street Journal has done this year.
We Let AI Run Our Office Vending Machine. It Lost Hundreds of Dollars.
An AI agent ran a snack operation in the WSJ newsroom. It gave away a free PlayStation, ordered a live fish—and taught us lessons about the future of AI.

AWS CEO Matt Garman says companies should not cut junior developer roles for 3 reasons:
1. junior devs are better with AI tools than senior devs
2. it doesn't make sense as a cost-saving move
3. removing junior devs breaks the talent pipeline
I agree #1 and #2

A great example of coding with AI properly - get to a starting point quickly, giving clear instructions, reviewing code thoroughly, comparing various approaches, keeping good code, deleting bad code mercilessly, optimizing for speed and test coverage, writing tools as needed & adding CI/CD 🚀 Super!💪
Here's Emil's 17 step guide to how he used VS Code agent mode plus Claude 3.7 Sonnet, Gemini Pro 3 and Claude Opus to build the new library - it's a fantastic case study in using LLMs for serious, prediction quality code (vibe engineering, not vibe coding) friendlybit.com/python/writi...

Fantastic interview with @kelseyhightower.com. Discusses DevOps, open source, AI hype and personal growth.
"All paths lead to self-learning"
"When people wear a title, they forget to evolve"
"Senior engineer, junior human"
The story about his first contribution to Kubernetes is inspiring 🎉!

Good video capturing journey of our industry, and the following topics: from servers to containers and serverless, #DevOps vs. #Platform engineering, of course #Kubernetes, of course #AI too 😜, tool sprawl/complexity and what's next? Worth a watch and Kelsey sharing his wisdom and experience!
It's rare that I get to reflect back on my entire tech career and my philosophy towards work and life, but this interview captures it perfectly. One of the few recordings of myself I've watched end to end. www.youtube.com/watch?v=HdUb...

Agreed. Definitely worth reading. It speaks directly to the question I have been asking the universe: instead of saying AI will replace humans, why not say AI will augment humans?
Cory explains this through the concept of centaur vs reverse-centaur, and the biggest myth that AI can do your job.

I've been driving Zed as my daily IDE for about a week and while it has improved greatly since the last time I used it, it still has quite a lot of issues that make me less productive or, sometimes, even force me to reach out back to VS Code.
Let's talk about those.

I remember the day watching the news in shock and disbelief. Just regular people who went to work. How do you even begin to make sense of that?
My heart goes out to everyone who lost someone and to the first responders who saved lives. I can't imagine your pain, but I feel it with you today.❤️

Bracket City's UI used to be simple and subtle. I used to love that.
But the new UI is different and bad.
Homepage with deep orange background with black text
Puzzle page with caps lock keyboard, lower case answers and fluorescent blue highlights.😡
It takes away the joy of doing these everyday.😔

Not sure why, but lately Claude in browser is generating several versions of an answer instead of just one per request.
For eg: I asked it to adjust my CLAUDE.MD file, and got 5 drafts at once 🤷♀️. This increases output tokens unnecessarily and in no time, it says you reached the 5-hour max limit 🙄.

Here is a typical chat with agentic coding for a big refactor (GitHub Copilot Claude Sonnet 4).
I give multiple tasks in single shot 'coz each instruction eats up Copilot Premium request budget ($0.04/inst). And agents are capable of doing multiple complex tasks, creating a plan and executing it.🚀💯

I see that GitHub Copilot Agent explains its thinking as it codes - feels collaborative and transparent, like a good peer programmer.🎉
Claude Code is more proactive, often suggesting the next step - feels more autonomous.🚀
Both are great in their own way. Ideally, we want the best of both worlds!💪

Trying out Wimbledon's new AI chatbot 'Match Chat' 🎾(powered by IBM watsonx) - very handy for match stats and insights, answered most questions well.
But for this specific match that ended in Thompson retiring due to injury, it struggled and kept asking about 'Match Context'🤷♀️.
