Upgrade guide - Getting started Upgrading your Tailwind CSS projects from v3 to v4.

I’ve been putting off doing that.

I’d approach this by first putting Claude code into /plan mode then giving it a prompt like:

“Upgrade this project from tailwind 3 to tailwind 4 follow this guide: tailwindcss.com/docs/upgrade... and take before and after screenshots to ensure no visual impact.”

I also tried it today for the first time today. Was impressed without even changing from the default free model. The TUI experience felt better too - less bloated.

Later, he tells a story about impartiality. In Sarajevo in 1992, he saw the shelling of two children’s funerals. “I wanted to do a piece to camera saying, this is the most monstrous war crime you can imagine. I wanted to rant.” Then his BBC instincts kicked in. “I just described what happened.” Nineteen years later, the piece was used as evidence against Bosnian Serb leaders Radovan Karadžić and Ratko Mladić. “I remember thinking, if I’d got on my soapbox, would they be admitting it in the war crimes tribunal? I don’t think so.

Scientists no Longer Find Twitter Professionally Useful, and have Switched to Bluesky Synopsis. Social media has become widely used by the scientific community for a variety of professional uses, including networking and public outreach. For

Bluesky is the new science Twitter, new study by @whysharksmatter.bsky.social and Julia Wester concludes!

"Results show that for every reported professional benefit that scientists once gained from Twitter, scientists can now gain that benefit more effectively on Bluesky than on Twitter."

It’s so sad when 80% of applicants hardly make any effort. Especially now they can get free personalised advice that could get them into the top 90%.

Nice! I switched the last of the apps I have with a redis dependency over solid queue today. So much quicker and easier to make changes like this in this day and age.

Wondering if this is more or less likely to be true now.

Might depend on definition of a SaaS.

Did it a couple of years ago and haven’t looked back. Was a very smooth experience then - expect it only to be better now.

Sorry I don’t think I can give you any good reason not to do it.

It’s Alex’s first day.

You want to help them make a big impact fast. You let them use your computer, email address & app logins. They’re so quick you can’t even see all the steps they’re taking.

What could possibly go wrong?

Why can’t we onboard LLMs the way we would really onboard an employee?

Visibility is Velocity Why visible progress beats speed: how incremental updates build trust, reduce risk, and change how complex product work is perceived.

Great short post from @mheap.dev: michaelheap.com/visibility-i...

It takes practice to deliver the right level of abstraction--too many details are not great.

But surprises are so so bad.

Even if Alice delivers a month later than Bob, people understand why and are more likely to accept it.
