My LLM coding workflow going into 2026: https://bit.ly/coding-2026. Specs, skills, MCPs, small iterative chunks, and always review what the AI suggests.

✍️ "Hard truths about AI-assisted coding" tips & tricks in my latest article: https://bit.ly/ai-assisted

While AI-Assisted coding can get you 70% of the way there (great for prototypes or MVPs), the final 30% requires significant human intervention for quality and maintainability.

Had a great time in New York giving new talks on Chrome DevTools & Software Engineering with Agents at React Summit & JSNation

"Chrome now shows each active tab’s memory usage" by @addyosmani https://medium.com/@addyosmani/chrome-now-shows-each-active-tabs-memory-usage-4f74876538e6

Honestly, this might do more to get web apps to fix their memory leaks than just about anything else.

"What makes an effective engineering team?"

I just wrote about this topic: https://addyo.substack.com/p/leading-effective-engineering-teams ✍️

At Google we found that psychological safety is the most important dynamic for an effective team. This was alongside other dynamics like dependability, role clarity, meaningful work and impact.

The #AppleBrowserBan Ends in the EU! 🇪🇺

After 3 years of campaigning by @owa and in a victory for developers and consumers, Apple will no longer ban third party browsers in the EU.

We will fight until we have won in every jurisdiction!

Your Browser, Your Choice!

Chrome is shipping <img sizes="auto"> support. For lazy-loaded images with **srcset**, this allows the browser to use the **layout width** of the image in order to select the **source url** from the srcset.

For lazy-loaded images, CSS is often available before the image load begins. The browser can take the actual width of the image from CSS and use that as if it was the image's sizes.

You may remember a while ago, we asked people to visit a little web app that grabbed their viewport sizes.

We had an idea in mind for a visualisation and article that today, we've just pushed live.

The ideal viewport doesn't exist https://viewports.fyi/

✍️ Good code is like a love letter to the next developer who will maintain it. It’s sincere & unadorned with unnecessary complexity.

The "Software Engineering at Google" book is now free to read online: https://bit.ly/swe-book Great insights on improving code quality & scaling engineering teams.

✍️ Software is a vehicle for delivering value to people: https://addyosmani.com/blog/software-value/

It is all too easy to become fixated on the tools at our disposal but, it is crucial to remember that these tools are just means to an end, not the end in themselves.

✍️ Stick to boring architecture for as long as possible: https://addyosmani.com/blog/boring-architecture/

Before adopting a new architecture or tech stack, ask yourself: Does it solve a specific problem for users, the business or developers? Is it worth the learning curve and potential instability? Is this going to help us further down the line?

Software is a vehicle for delivering value to people. Don’t get lost in the tools; keep your sight fixed on the value created.

Trying Threads: https://www.threads.net/@addyist see you there if you are too!

I don’t see it fully replacing Twitter, but can see it engaging Instagram users (not previously using Twitter) and a % of Twitter users still looking for new home. There’s of course the “can I trust Meta?” dimension and time will tell how the market weighs this. So far I’ll say the community vibes there have been positive.

"In 2023, the dominant cost of JavaScript is download and CPU execution time"

[Pardon the Lighthouse toots..]

In Lighthouse 10.1, we've upgraded reporting of third parties and their impact:
➡️ Audit tables are now grouped by party
➡️ Detected third parties are tagged with their category (and linked!), so it’s easier to identify their purpose

Didja know Lighthouse has a diff tool? 🤔 Compare two reports and see all the changes.
