The things that are worth doing are the things that you suck at. Kubernetes has been a humbling year-long journey. Embracing the suck was not fun, but I'm now prepared to ship anything anywhere. The role SRE sounds a lot more appealing now than a year before.
This was my thought when I saw the Supabase execs complain about no specific compute instances available from AWS & sniping back at the community it’s out of their hands. A cell-like design where you can split diff compute instances yourself. Who owns your availability? YOU!
Hitting cloud account limits was one of the biggest challenges we had when scaling Confluent to billions of QPS and petabytes of data. At scale, you will frequently hit cloud limits. Some of these were not documented and we only discovered them when it happened. These limits…

Reminds of Byzantine Generals Problem and the way it caused failure of leader consensus for RAFT in etcd at Cloudflare: blog.cloudflare.com/a-byzantine-fa…
Even if you're avoiding AI because "you love writing code" (great!), do yourself a favor and ask it to audit the code you wrote, especially tests for coverage analysis. It's very good and will find your bugs. Example: ampcode.com/threads/T-31ba… Cost me 42 cents. I didn't blindly…
Any component can fail at any time in distributed systems. How do you communicate in the face of unreliability? It's not easy! This is classically known as the "two generals problem" and is a great way to think about communicating over unreliable channels. General A and…

Introducing Claude Haiku 4.5: our latest small model. Five months ago, Claude Sonnet 4 was state-of-the-art. Today, Haiku 4.5 matches its coding performance at one-third the cost and more than twice the speed.

Don’t do microservices if you don’t have distributed tracing + distributed logging from the get go. traceparent and correlationId are your friends.
We had microservices calling microservices calling microservices. One API request triggered 12 internal calls. Believe me, Tracing was a nightmare. Debugging took hours and hours. Adding a new service meant updating 5 other services. The problem isn't microservices. It's what…
You replaced "two storage systems and vibes" with "one storage system and faith in the CRUSH map."
There is no such fundamental principle - that slogan is just a prioritization technique when getting complex things working. Performance is part of correctness. You can't go back and optimize 100s of different routines after the fact. That is what we call "death by a thousand…
Prediction: Cloudflare and Vercel will fight 'til the death-of-the-hyperscalers The pace of innovation at each is spectacular and the real losers will be the ones not in the fight
we didn’t like the benchmark results so we made @cloudflare workers faster & set the record straight⚡️ here’s how 👇

1/ 🚨 NEW NPM MALWARE CAMPAIGN. Yes, another. North Korea’s “Contagious Interview” campaign is escalating: 338 malicious npm packages, 50,000+ downloads -- 25 still live. Aimed at Web3/crypto devs & job seekers via slick recruiter DMs → git clone → npm install → compromise.
I really hope @github starts doing this soon. Agents understand md better than HTML. Every time I pass a reference to a repo or file using GitHub permalink, Claude Code downloads ~100KB (sometimes over 200KB) of data and burns through my tokens trying to contextualise it.
When Claude Code fetches Bun’s docs, Bun’s docs now send markdown instead of HTML by default This shrinks token usage for our docs by about 10x

Still a lot of polish to go, but soon update popups will never show up in your demos again @romainhuet or anyone else. 😎
My favorite thing when people migrate to PlanetScale is how giddy they get about Insights. A single dashboard that shows you tons of opportunities for improving your query performance. A lot of people are even able to downsize their clusters after cleaning up their queries!
We added 2 new columns to PlanetScale Insights: - Bytes returned - Bytes returned per query These metrics can help you find unexpectedly large query responses and the most significant contributors to network egress traffic.

Vite+ now has a website. Licensing for existing projects remains MIT. Whereas Vite+ will be "source-available" and free for open source, non-commercial usage. viteplus.dev
