vim is kiki, and emacs is bouba

@netcapgirl Imagine monitoring the situation from up there

maybe the hardest selfie of all time

@eatonphil "At this point I don't really want to keep trying since named format arguments were a key part of the static site generator." brutal but fair 😂 I like how clear the writing is!

I've wanted to look at Mojo for quite some time. It is definitely not yet a superset of Python. But with that seeming to be a goal and with the standard library being open-source there is a very clear area for you to go and contribute to a well-funded major programming language.

Excited to announce Claude for Open Source ❤️ We're giving 6 months of free Claude Max 20x to open source maintainers and core contributors. If you maintain a popular project or contribute across open source, please apply! claude.com/contact-sales/…

I started a software research company

@ekzhang1 would love to read an essay on this (I also find this oddly relatable!)

5 years ago, I was making programming languages, dreaming up interfaces, learning graphics, building with Rust/Wasm. everything was new. how beautiful were the things you made if you put yourself out there and were a bit scrappy? then at some point I GOT A JOB and started doing INFRA and working with COMPLEX CODEBASES and PRODUCTION SERVICES. and now I am like every other software engineer. lol

@swyx @nytimes What article was that?

just found out from @nytimes that the man shortage in NYC is so bad that dating events are charging women $100 and men $0 and the attendance ratio is still 3:1 do u new york girls know how insane you sound right now to san franciscans, just… move? pictures taken 5 mins apart right now

@AtharvaXDevs Looks interesting, though I'd be curious to see an updated / modern take on it. S3 has seen improvements to its consistency guarantees since 2008, and notably it now has Compare-and-Swap functionality.

currently reading btw

@jarredsumner Bun.rrule() next? 🙏

In the next version of Bun `Bun.cron(file, schedule, name)` schedules a function to be called on a recurring interval

@turbopuffer Curious if you had a chance to load test the setup? What's the max throughput you can achieve with the single file approach?

queue.json on object storage is all you need to build a reliable distributed job queue → FIFO execution → at-least-once delivery → 10x lower tail latencies tpuf.link/queue

In the end, I think software engineering *is* still here to stay -- but the nature of it (our relationship with "code" as an artifact) will change, and the demand for programmers in many sectors will take a hit.

At one level, I think "how" we've done our work in software has always been changing. Languages, tools, methodologies, paradigms - we've always had to keep adapting and learning. Yet this change feels more different than the rest, somehow.

@ArjunGuha "You can think of this as containers 2.0: we don't need containers, and this makes the world a better place. Trust me, I was there before containers" incredible

SlopOS requires a machine with a 1.44" high density floppy drive and an HDD. You can run it on QEMU on a legacy OS. The release also includes the Codex transcript that built it in a few hours: github.com/arjunguha/Slop… (3/3)

Introducing SlopOS: a new vibe-coded, operating system for safety-critical applications. SlopOS leapfrogs existing OS designs with first-class support for a new memory managed, object-capability based programming language for the userland and core kernel routines. (1/3)

THE UNBRIDLED GREATNESS OF TRAINS WILL ENDURE FOR A MILLION YEARS

@PostgreSQL has long powered core @OpenAI products like ChatGPT and the API. Over the past year, our production load grew 10× and keeps rising. Today we run a single primary with nearly 50 read replicas in production, delivering low double-digit millisecond p99 client-side latency and five-nines availability. In our latest OpenAI Engineering blog, we unpack the optimizations we made to to scale @Azure PostgreSQL to millions of queries per second for more than 800M ChatGPT users.

@mitchellh How did you create the diagrams in your blog post?

Rejoice, the rare but massive memory leak in Ghostty (that particularly Claude Code users would hit) has been found and resolved. This leak has existed for almost 3 years! It's in an uncommon code path that CC happened to hit. I blogged about it: mitchellh.com/writing/ghostt…

It's 2026. AI writes most of my code. Now what?

New blog post! Writing mutexes from scratch in Go rybicki.io/blog/2026/01/0…

TIL reentrant locks are considered harmful? These are locks that are OK to call .acquire() on by the same thread more than once. For example, Java provides ReentrantLock out of the box in java.util.concurrent.locks. But they aren't available in Go: groups.google.com/g/golang-nuts/…

Happy New Year all!
