Today I'm writing about the Go's Profile-Guided Optimization (PGO), where you hand the compiler a profile of a real run and it optimizes the code that is actually hot, without touching your source.
One interesting fact is that the compiler doesn't use the whole profile, it just keep a subset of the information, the "call edges" (caller, callee, where the call happens, and how many samples hit it).
From those edges, the compiler does three things: guesses the concrete type behind interface calls, inlines much bigger functions at hot calls, and aligns hot loops to cache lines. We will see each of those in detail.
The article will be out tomorrow!

Today we're launching @costgraphai.
It tells you what your infrastructure costs, whether that spend is justified, and then fixes it.
Cloud, Kubernetes, CI runners and SaaS. One view.

The web rewrite is working.
On a slow connection, the old X web took more than 22 seconds to show the first post on a profile. The new X web does it in 2.7 seconds. Here's how we did it, and how we're rolling it out one country at a time.

A year and 6 months ago, I posted about optimizing costs with a vibe coded UI and an API that God knows should not have existed.
Today, the service has daily signups, keeps growing in revenue and boasts at least a 30% reduction in costs from our insights.
@costgraphai launches officially to the public with more features and taste than ever, it works on-prem too. Be there this Saturday.

Keep exposing them, I spoke about opposition using international influencers since a lot of Nigerian influencers are working for APC.
I’m glad we are gradually getting there🤭🤭

Amazon's leadership is very good at writing, but you still need to read between the lines.
What I read between these lines:
Engineers who are not "product engineers" (aka eng + PM interest) and don't like to be customer-facing will not have a future inside of Amazon

Come work with me at Resend. We’re hiring a Platform Engineer.
What I love most about Resend is solving scaling problems across infra, code and processes. Seeing those solutions have a real-world impact is amazing. And I get to do it with the most talented, kind people I’ve ever worked with.
You’ll be a great fit if:

- You have an AI mindset and are curious about how it changes the way we build
- You take ownership and use the autonomy to improve things at every opportunity
- TypeScript and Go are what we mostly use.
None of this is a hard requirement, and the full details are in the career link.
Perks:
🌍 Fully remote across the Americas/Europe time zones
🛫 Two off-sites per year
♥️ Did I mention working with incredibly talented and kind people
💰 Above average compensation, depending on location and experience
