Somehow my X feed is now full of people arguing about differences between different Christian sects. Obviously a lot of this is to farm engagement. I hat how this platform is designed to bring out the worst in a lot of people and reward them financially for it.
But all that said, I came to realize a perhaps useful metaphor to explain the false choice between salvation by grace and the importance of good works.
The phrase I often use is "essential but not sufficient". This applies to a lot of things in life, technical discussions at work often involve this idea.
But good works in Christianity is perhaps the most important example of this. Christ clearly taught that we must repent, be baptized, and follow him by doing good continually. Good works are essential to salvation according to Jesus.
But good works alone is like drying to drive to work with a full can of gas and no vehicle. You won't get very far and the vehicle is what actually trabsports you. But also a vehicle without fuel isn't going to go very far.
Christ is the vehicle of salvation, we can do nothing without him. But he expects and commands us as our Lord to do what we can to become better and more like him.
Christ will never save us in our sins, but he will save us from them if we let him by repenting and doing good continually so that he can sanctify us.

If you remember this, it might be time for bifocals.

This is so true! Working on Vercel CDN is challenging and often intense, but never, ever boring. I've used more computer science in this role than any previous job.
This was fun to work on. It was our third CDN project where we designed and shipped JSONL based formats that are both technically efficient and operationally simple at scale.
The Vercel CDN makes over 80 million routing decisions per second.
We cut P99 metadata lookup latency by 91%, helping requests reach your pages faster and speeding up deployments along the way ↓

Starting August 10, Vercel's CDN will stop stripping the 𝚂𝚎𝚛𝚟𝚎𝚛-𝚃𝚒𝚖𝚒𝚗𝚐 response header and pass it through to the browser.
Report backend metrics like database query time, and they show up in the network panel and the Performance API.

“All are invited to participate in a unified fast to express gratitude for religious liberty and to pray that it be strengthened throughout the world,” wrote Church President @OaksDallinH and his counselors in the First Presidency.

It's been so much fun to watch this be developed internally.
WebSockets are now supported on Vercel.

Remember everyone, LLMs are amazing math models that can make extremely correct *looking* code.
By pure coincidence, these are sometimes right and the more guardrails and feedback you give it, the more likely it's actually correct.
But finding error is *very* hard, by design. – at Arkansas, USA
Imagine if you had one of those genies that would grant wishes, but always in the most subtly wrong way while technically doing exactly what you asked.
Then imagine you asked it to write code that looked correct and big free.

When Opus 4.5 came out, it was a one-way door to a new way of engineering. Agents now do most of our coding.
Knowing the inherent flaws and over-confidence of LLMs, we sent a clear message to our teams. Vibing and mission-critical infrastructure don’t go together.
We’re sharing some of our early internal guidance in how we’re “agenting responsibly”, prioritizing security, durability, and availability at all times.

This was a fun project to work on! Again we balanced technical performance with operational complexity and found a really nice solution.
Bulk redirects on Vercel now scale to 1 million per project with near-constant lookup time.
We shipped the simplest thing first, profiled it in production, and iterated from there ↓

I've been iterating on a new encoding format that's LLM friendly. It's a very interesting challenge because tokens are not bytes and especially challenging when you consider that the LLM needs to be able to comprehend the custom format. This makes competing with JSON hard.
