The Day a Border Radius Cost 45 Megabytes

What people were saying

The day's most-liked Linear post was not about issues, cycles, or agents. It was @penzington explaining that a border-radius on all four corners, rather than just the bottom two, cost 45 MB of GPU memory and produced a blank frame on every keystroke. The fix was to round fewer corners. That's it. 850 likes for a CSS property, which tells you something about who follows Linear engineers.

The other team thread was quieter but more product-shaped: @guglielmodanna posted that callout components had landed in Linear docs, and the Linear org promptly piled on in a coordinated-but-charming way. @karrisaarinen said docs keep getting better, @artman noted the callouts work in issues, docs and reviews too, and @penzington just posted the raw markdown > [!TIP] syntax, which is how engineers say "nice." Outside the company, @heyimgustavo offered the four-word review of Linear docs: simple, fast, beautiful, works.

The praise

@cjc shared the day's best customer number: a $7B healthcare AI company that left "a certain legacy issue tracker" (Jira, obviously, but unnamed for sport) and has since logged 80,000+ customer requests, weighting them by frequency and revenue. Elsewhere, @arihantCodes shipped an open source shadcn data table explicitly inspired by Linear, which is the highest form of flattery in frontend. @pdotcv posted stickers, and @yannglt confirmed Paul is cooking.

Notable anecdotes

The agent-plumbing genre keeps growing. @dexhorthy hosted a show on "software factories" where one guest runs a discuss/do/compound loop with Linear as the frontend and agent sessions on Mac minis. @guzmanpintos diagrammed a seven-step pipeline where a Slack complaint becomes a Linear issue, then an agent PR, then a review, then a human merge. @thisiskp_ said building "a Linear for my agents" was a great decision, which is either a compliment or a competitive threat depending on your mood. And @jgreze argued the future is one or two agent entry points, not a Linear agent for project management and a Salesforce agent for sales.

On the softer side, @brettmarlin recapped the Lenny & Friends Summit and quoted Karri Saarinen's talk title, "Context is the Product," and @toriistorii__ reported on a Linear-and-Merge happy hour serving something called a merge martini. Also, @penzington asked, in Polish, which companies in Poland use Linear, and got 61 replies, which is a pretty efficient market research method.
