Wow, this post went absolutely viral by bluesky standards. Literally dozens of likes.

FormKit 1.7.2 is out! 🎉

🐛 Fixes:
• Dried up the memory leaks

Code block showing how tempo can format and parse internationalized date strings.

The date time library that can format and parse Intl.DateTimeFormat, work with timezones natively, and tree-shakes to zero....goes 1.0 🎉

The amount of grave dancing on this platform is truly despicable.

I've released 3 projects recently:

- jsonreader (parsing for partial json)
- dmux (multiplexer for claude code)
- zodown (Zod 4 -> Zod 3 runtime converter)

They're like hidden gems though. No one knows about them 😂

announcing: zodown

A Zod 4 -> Zod 3 runtime converter.

Why? Lots of packages don't support Zod 4, but you want to write Zod 4 because you live in the future:

Nope. Although I may use Claude in ci mode as fallback for when open router isn’t available. But I want new panes to open fast so you can get going.

course, and today is special because the course is open for preorder…and that comes with a HUGE 50% discount, but only for the next few hours.

to crap as soon as the project got even slightly complicated.

The solution isn’t a gimmick. There is no “this one trick made me a 10x dev” going on here.

**Using AI is a skill just like any other dev skill.**

So I’m going to teach that skill in this…

It’s simple. Coding w/ AI is binary, either you get a huge productivity boost OR flow-breaking, atrophy inducing, malaise producing, spaghetti code.

The difference between the two?

**it’s a skill issue** 😂

I know because I’ve been on both sides of it 🙂. My first few projects went straight…

📣 I’m partnering with @Bitter_Brains to teach a course on AI Driven Development (@aidd_io).

I’ve become at least 3x more productive at coding in the past 2 years, but for a lot of devs AI is actually slowing them down…why?
…

Never heard of it, so I googled it. I think I know why it’s not popular…

This has to be one of the worst looking websites I’ve ever had the displeasure of seeing.

Right or wrong, I assume a bad looking website is a reflection of competence.

My morals are available more in the $75/month range

If you know that unlock you should certainly tell me, but also the teams running Twitter and bluesky

Yup! You should make a public article “how to make bluesky good” and explain all the knobs and whistles and tips and tricks to create a good experience, but especially one that fosters actual conversation

Agreed! I want to recreate that time

I don’t know….im a good faith participant who wants to have tech and tech adjacent conversations but:

1. They don’t appear to be happening.
2. Whenever I post, even in reply to folks, zero engagement.

So it feels about as relevant to me as truth social

It was?

The effort it takes to get a good feed might be the problem. Whatever it is, this place is crickets for me 😕😢

Even the posts that I do see have no engagement. Kinda sad.

Why did you leave me Daniel! Whyyyyyyyyy

It’s too bad this platform failed too, we’ve now just further fragmented the dev community.

Sadly I don’t think Humpty Dumpty gets put back together.

I suspect you’re correct, but what a sad thing for people to dislike another human for their opinions.

Honestly it’s unlikely to solicit a conversation. Bsky algo will show this to 4 people total.

Hey, can someone explain why so many folks in tech don’t like DHH?
