What it does
You sent the Slack, the email, the DM — and they didn't see it for hours. Knock lives in your Mac menu bar and lands your message dead-center on their screen, then shakes it. Impossible to ignore. Plus live notes, time capsules & doodles. $9 once, no subscription.
A tiny Mac app that lands your message right in the middle of someone’s screen and shakes it — impossible to ignore. For the teammate who never sees your Slack. $9 once, no subscription.
You sent the Slack. The email. The DM. They're heads-down and didn't even notice — for hours. Knock takes over their Mac screen and shakes your message until they look. Your message, dead-center on their screen. Impossible to miss. Slack pings get muted. Emails pile up. DMs get “seen” and forgotten.

Homebrew 6.0.0▲1,481Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
