at the planescale movie night of the Elizabeth Holmes doc, everybody in the cinema has just been laughing so hard since the start on Nathan Fielder’s filming style and his very plain reactions to Elizabeth breaking down 10/10 best comedy movie of the year

I honestly don't even know how @kaylee_dev & @BurnedChris got it this fast. v2 was 89ms. Is v4 going to give back users their time?
Replying to @BurnedChris
The banner arrives with the page. Your build fetches the policy once. The server decides each visitor with 0 network calls and ships the banner in the HTML. On CookieBench, our open benchmark: on screen in 27 ms, 0 ms of blocking time.

c15t v3 is out. Paste this into your coding agent and see what it sets up: Set up c15t in my app: c15t.com/SKILL.md On CookieBench, our open benchmark, its banner is on screen in 27 ms. Moving off another consent tool? My DMs are open.

Well that's me sore before the flight. I guess they didn't like my last name or something.

how to see your Spotify Wrapped top played songs early... create a Prompted playlist using this prompt: Using my Spotify listening history from January 1, 2026 through today, create a playlist of my 100 most-played songs. Rank them from most played to least played based on how many times I actually listened to them. Do not add recommendations or songs based on similarity. Include exactly 100 songs. Great, now you've got a new playlist and can manipulate your top 5 songs before your guilty pleasure songs get seen by your friends

The first feedback on the Inth CLI: let me install it without npm. Now you can: curl -fsSL inth.com/cli/install.sh | sh And "inth update" keeps it current.

I like that our customers who go live with us just tell us what our value is and what's important to them. You can spend months trying to figure out wording before launch, or you can focus on getting just 1 customer and they just tell you how to pitch, rather than you overcomplicating it. Inth's cookie banners get you better metrics because they only show in countries that require it.

You publish a privacy policy and then hope prod and runtime match it going forward. but when engineers & marketers change product and the site everyday, they go unnoticed unless it's declared, or found out by an angry user. Inth's audits now catch every risk before it goes live

Think it doesn’t apply to you? It does, and your startup is probably next on Vivek Shah’s list to send you a demand letter for breaking the CIPA wire tapping law.

Your startup could be one privacy mistake away from a $10,000 CIPA demand letter. It’s coming. Will you be ready before it lands?

TIL, Code review isn't dead, it's just about who owns the decision. ty @BurnedChris, all of our privacy compliance is now better for it

When Chris first pitched Inth at me to join him in the company, it was never only about having the fast cookie banner. Today, we launch the next stage of Inth to help catch any privacy issue before it reaches production and so it never blocks growth again.
