We recently ran a successful live failover of our control plane database from Azure West US to East US 2. Our goal was to validate that Vercel can survive a complete regional failure of its core database. Here's the full breakdown: vercel.com/blog/prepar...

Preparing for the worst: Our core database failover test - Vercel

On July 24, 2025, we successfully performed a full production failover of our core control-plane database from Azure West US to East US 2 with zero customer impact.

I'm pleased to have had a small hand in this (all actual credit to @tomocchino.com). it is music to my ears — and, I hope, to open source maintainers and community alike... 🎶 specifically, I'm delighted that @vercel.com (and others) _see the value_ in aiming for openness, portability + choice.

@e18e.dev CLI is available! Looking forward to trying it out!

I wonder how that correlates to the training data. If that prompt is successful does it also mean that devs do better with positive affirmation??

Explained being On Call to my two year old daughter, so she has an intimate understanding of capitalism now. She wants to know who’s calling me, but otherwise seems ok with it.

Most annoying thing about SQL is that you can't chain WHERE clauses. Same annoyance as languages that don't allow trailing commas on lists.

Why the “experienced” part though? How does it distinguish between experienced and inexperienced anyway?

Why does every system promote start with “you are an experienced software engineer”?

JSON is widely considered a machine readable format. It’s ironic that it became a standard precisely because it was human readable. And even more ironic that LLMs are reading plain text / natural language formats now.

I had switched to Ask mode in cursor instead of Agent, I guess it was my fault. Wish it had prompted me though instead of telling me it can’t run the commands

Mehul Kar @mehulkar.com · 18/07/2025

Mind boggling that slackbot doesn’t an have LLM mode yet.

Amazing! Can’t wait to add some @e18e.dev energy at Vercel 😃

Oh, yeh this chart is JUST lint time, not the other things.

as opposed to parsing, you mean? we used turbo to run lint in each package of the monorepo, so there's some overhead with concurrency. biome runs on the whole codebase. (p99 is to capture "whole codebase" situations, the p50 for eslint is much lower because many packages get skipped)

sorry bad joke, I guess. I thought when you asked "are you", you were referring to whether or not i'm happy in life (as opposed to with biome), and I was following the joke :D

130

biome is great, but it can't fix me matteo

120

I don't remember the bottlenecks now, but I think typescript-eslint plugin was one of them

yeah we dropped a few, but got all the critical stuff. We also contracted with Biome to implement type inference for the noFloatingPromises and noMisusedPromises rules that we considered critical!

Vercel @vercel.com · 08/07/2025

Dropped @eslint.org in favor of @biomejs.dev in our 2 million LOC codebase. p99 ESLint times in CI went from ~19m down to ~2mins. A bunch of caveats, but we're...happy?

I wonder if there's overlap between the people who're really good at writing clear prompts for coding tasks and the people who're really good at writing clear git commits. Seems that prompts could be seen as writing the commit first?

if you can, avoid exporting the types of a dependency. some of the migrations we've done are such a pain in terms of backwards compat because of this 😬

the word might have the same root as the word for when you're trying to get somewhere quickly and every traffic light is yellow

What is the german word for when you're trying to do something quickly and every single UI lag, password reset and confirmation comes up at the same time. Also you bump your coffee mug and it spills.

It should be a red flag if the most visited doc in your eng org is "how to force merge a PR"

Mehul Kar @mehulkar.com · 23/06/2025

A good reason to use node:test is that you can focus on upgrading your runtime, instead of upgrading dependencies.
