Hello, friends! After 10(!) years of #AdventOfCode, I've made some changes to preserve my sanity: there will be 12 days of puzzles each December (still starting Dec 1) and there is no longer a global leaderboard. Read more: adventofcode.com/2025/about#f... adventofcode.com/2025/about#f...

It's great to see things shifting back to the principles we were promoting through the mid 2000s while working on RSS, Atom, Activity Streams, and ironically OpenSocial. Those efforts ended up being short circuited by Twitter and Facebook competing to own the walled gardens. We've come full circle.

ME, IN TEARS: you can't just say every single part of a computer system is a file UNIX, POINTING AT THE MOUSE: file

Regarding goroutine & unbuffered channel interaction, found myself repeating this multiple times. Maybe it's time to write it down for reference. Early return + unbuffered send = goroutine leak. rednafi.com/go/early_ret... #golang

America is beautiful, contradictory, unfinished. I am proud of our country even as we constantly strive to make it better, to protect and deepen our democracy, to fulfill its promise for each and every person who calls it home. Happy Independence Day. No Kings in America.

Proposed incident metric: how often at least one person says "but this is impossible" when considering a theory that turns out to be true.

“no way to prevent this” says only programming language where this regularly happens

Looks like the Google Cloud incident report is out: status.cloud.google.com/incidents/ow... A June 12 policy update with unintentional blank fields triggered a crash loop in Service Control code that lacked proper error handling, causing binaries to fail globally.

A SIGTERM is issued by the operating system; my process effortlessly dodge rolls it, then immediately executes a perfect parry against the MMU. Before it can recover, a null pointer has been loaded into EBX. The kernel groans at my shit.

happy to finally announce it! @cloudflare.social is now backing @pkg.pr.new's data infrastructure! thank you so much everyone for supporting the tool and making this possible.

This is the one timeline where there may be future history books with a chapter on Roganomics.

Sounds like a pretty good start to a cozy adventure. What do you think? #indiegamedev #gamedev #gameaudio #videogamemusic

Really interesting thread here. Stored procedures can move mountains, and there are definitely ways to make them feel nicer to use. But you're not going to have fun pitching them to your team.

New article out: "Cloudflare Durable Objects are Virtual Objects"🚀 This pops up a lot and is a mindset shift from the traditional way of thinking on "creating" and "destroying" resources, so I wrote a few thoughts how to think about it. www.lambrospetrou.com/articles/dur... #DurableObjects

I'm incredibly excited to announce that we're making Hyperdrive available on the Free Plan for Cloudflare Workers! To celebrate this, we put together a deep dive on how it all actually works under the hood. Come take a look, and give Hyperdrive a try! blog.cloudflare.com/how-hyperdri...

I’m going to do a 🧵 about making retro-style games in C/C++, and also about getting them to run in a browser.

A community member just shared this cool article about how to rig up a Worker and AWS IAM to get Hyperdrive working well with Amazon DSQL. It's always fun to see the people build cool stuff on Cloudflare! www.ai.moda/en/blog/auto...

We finished rolling out edge caching for Hyperdrive earlier this month - cached queries are now up to 10x faster. This is reflected in an average 50% decrease in session duration for *all queries*! ⚡️ just landed it in the new Cloudflare changelog: developers.cloudflare.com/changelog-ne...

The way I explain AGI to non-tech people is it's the belief that if I read enough book to my dog, there is some threshold at which it becomes a blackbelt in Karate.

A big shout-out to @jasnell.me for landing experimental QUIC support in #nodejs core 🥳 And thanks to @yagiznizipli.com and @pimterry.fyi for reviewing it. It'll be awesome if QUIC becomes stable in NOde.js 24.x LTS. github.com/nodejs/node/...

Return-to-office (RTO) mandates lead to abnormally high employee turnover, especially for female/more senior/more skilled employees. It also takes significantly longer to fill these job vacancies after RTO mandates. papers.ssrn.com/sol3/papers....

I had missed that ByteDance had a 2022 VLDB paper on their HTAP database, which combines an Aurora-like shared storage system with Apache Flink to create a shared-storage separate-engine HTAP system. The "Related Work" section is a good HTAP survey too. www.vldb.org/pvldb/v...

Personal tech blogs are still some of our favorite context on the Internet and this post by a community member is peak tech blog by our standards. Dig into Ubuntu, k3s, kvm, subiquity auto-install and learn new tricks along the way. Bravo @kubedoll.com kubedoll.com/posts/ubuntu...

Celebrating my 1-year anniversary on the Cloudflare Hyperdrive team by shipping query cache latencies so low they break the demo page's formatting. Here's to building a better internet.

how do you all remember every UUID? I find it really hard. so I wrote them all down on every uuid dot com the list has fast search across all 2^122 values (so you can find your favorites) - hoping to add some social features like "trending UUIDs" soon!

Hello, Bluesky users! I curate and maintain list of resources on testing distributed systems. You might have seen it before. It's a good one, if I may say so myself. asatarin.github.io/testing-dist...

Is #DataBS interested in the internals of streaming engines? The next release of arroyo.dev (0.13) has a new feature in the core dataflow called operator chaining which gets at some of the interesting details of how these systems work. So let’s dive in to streaming dataflow 🧵

Async/await in #Rust is well suited for use in microcontroller-based embedded systems with no operating system, little memory and no heap. #Embassy is an async runtime that makes that possible. Great talk by the creator of Embassy, Dario Nieuwenhuis #IoT #embedded #esp32 youtu.be/H7NtzyP9q8E?...

For my last class this semester, I tried to cram our Advanced Database course into one lecture. We cover the following database systems in 60min: youtu.be/fr5lIchF6pw • Google Dremel / BigQuery • Snowflake • Amazon Redshift • Yellowbrick • Databricks Photon • @duckdb.org • TabDB

As a thanksgiving gift for y'all, Workflows now support 512 steps per workflow (instead of only 256) 🚀
