Those benchmarks from @t3.gg revealed some interesting issues in Workers. Happy to say it's all fixed now, save for some lingering next.js-specific stuff we're continuing to work on. Thanks for the reproducible test cases, @t3.gg.

the things people see you do are the things they'll ask you to do. if you want to get asked to do certain types of work, make sure people see you doing that type of work

So this screen in @onlineornot.com has always been slower than I wanted - around 2.3s(!) to load 10 rows of data from the GraphQL endpoint.

It was the first screen I ever built (4+ yrs ago), and I leaned heavily into GraphQL resolvers because I assumed it'd be fast.

realised i was missing a pretty important empty state in @onlineornot.com today: when you search for something and there are no results

fyi founder friends — new scam to watch out for
A sneaky scam I've seen a few times now:

Someone writes into support to demand a refund for a duplicate charge.

"oh crap!"

But their email is nowhere in my system, nor is their name...

TIL there are SaaS vendors that raise their prices automatically year over year for existing customers

surely that increases churn?!

Quite an excellent piece. Max and I don't agree on everything (some of our lessons learned contradict each other), but I love having my thinking challenged, and I'm probably wrong on some of these!

Always fun to get emails like these from @onlineornot.com customers

crazy how effective positioning is

"uptime monitoring for your software team"
- weak, tired
- been there, done that

"get alerts when your team vibe-codes your product offline"
- wired, locked-in
- been looking for this for weeks, sign me up fam

fresh off a 28hr flight and have a whole day of work ahead of you?

you will certainly not regret having "two double espressos before 9am"!

think about your audience of course, but the *vast* majority of readers online aren't impressed by your use of words like utilize, leverage, operationalize, etc.

if anything, you're confusing them.

just say use.
Random tip: literally anywhere you utilize "utilize" you can just use "use."

Literally. Anywhere.
