Code example showing the usage of Temporal.ZoneddateTime ```js // London DST starts: 2026-03-29 01:00 -> 02:00 const zdt = Temporal.ZonedDateTime.from( "2026-03-29T00:30:00+00:00[Europe/London]", ); console.log(zdt.toString()); // → "2026-03-29T00:30:00+00:00[Europe/London]" const plus1h = zdt.add({ hours: 1 }); console.log(plus1h.toString()); // "2026-03-29T02:30:00+01:00[Europe/London]" (01:30 doesn't exist) ```

Temporal is now Stage 4 at TC39 🎂🎂🎂

Thanks to all the other champions of JavaScript's new date-time API. It has been a wild ride over many years!

I wrote a blog post explaining how we got here 📜

bloomberg.github.io/js-blog/post...

A JSON file representing a source map. The code contains: { "version": 3, // Always the integer 3 "file": "out.js", // Optional: name of the generated file "sourceRoot": "", // Optional: prefix prepended to each entry in "sources" "sources": ["foo.js", "bar.js"], // Required: list of original source URLs/paths (or null) "sourcesContent": [null, null], // Optional: inlined source text, aligned with "sources" "names": ["src", "maps"], // Optional: symbol names referenced by "mappings" "mappings": "A,AAAB;;ABCDE", // Required: encoded mapping data (base64-VLQ deltas) "ignoreList": [0] // Optional: indexes into "sources" considered "third-party" }

Source maps are a vital part of modern web development, but the lack of a standard made it impossible for us to add new features or improve the debugging experience.

This is the story of how we standardized source maps and how we continue to ship features through standards 📜

God, Human, Animal, Machine: Technology, Metaphor, and the Search for Meaning Technology, Metaphor, and the Search for Meaning

The AI/consciousness debate here is just persuading me to go re-read "God, Human, Animal, Machine" - a lovely book that uses AI as an excuse to talk about history of philosophy. bookshop.org/p/books/god-...

AI Didn't Break the Senior Engineer Pipeline. It Showed That One Never Existed. Most organizations never had a model for developing engineers. They had an environment that produced growth by accident. AI just made the luck run out.

If coding is your favorite part of software engineering, keep coding. AI doesn't stop you. But if coding was the only part you were good at, that's a different conversation. The job was always bigger than the code. #bransoncognac blog.bryanl.dev/posts/ai-sen...

We turned away from the light when we invented a way to go online without the computer screaming in warning.

As a company, we @moment_dev have a single ambition: to make it possible to run your entire business out of a Markdown file.

lol "wrote it with AI for a promo project" is also a good theory

Very generous of you, assuming it's implemented with AI rather than with a static list words! 😁

Over the last year or two, engineering blogging has gotten so ... bland. I feel like most of my tech reading is getting clogged up with posts written in a business hustle tone: overwrought and repetitive without saying much of substance.

So SCOTUS, with its fabricated-out-of-thin-air immunity doctrine, has actually made American presidents less accountable than LITERAL royalty.

My hot take on Taiwan is that I wish we would fully commit to the defense of Taiwan and also that saying that out loud may be an absolute disaster especially with this President.

Also you should visit sometime, it's nice.

Wow congratulations!!! Well-deserved!

Homeland Security Wants Social Media Sites to Expose Anti-ICE Accounts

New story up on the Homeland Security Department’s new tactic: flood social media companies with subpoenas to unmask anonymous accounts that criticize ICE or monitor the movements of ICE agents.

In college I took a class in history of animation. I remember reading somewhere that CGI didn't speed up production schedules all that much. It just increased the number of drafts / alternate scenes the animators did.

Maybe that ends up being the future of software too?

As a programmer, this matches my current pattern using agents to write code.

I find that I use the agent to explore a few different prototypes. They're wooly and over-engineered.

Then I go back and rebuild it with simpler abstractions based on what I learned from the prototypes.

One of the reasons I so greatly dislike the “can men and women be friends?” nonsense (yes, full stop, shut up) is that it casts suspicion on people with opposite-sex friends instead of where it more often belongs: on people with no opposite-sex friends.

oh no, not like that

I'm frustrated with how unstable the Go / protobuf / rpc ecosystem has been. Between gogo, grpc-gateway, jsonpb, protojson, and all the buf tooling, there's been a ton of churn.

Has it been like this in other languages or is this a Go-specific problem? #golang #protobuf

Medium gives employees Friday off to participate in national strike protesting ICE | TechCrunch Activists behind the general strike are calling for "no work, no school, and no shopping" amid a push to defund ICE, which has escalated raids in U.S. cities, killing several people, including two U.S. citizens earlier this month in Minneapolis.

Agent Psychosis: Are We Going Insane? What’s going on with the AI builder community right now?

Saying there must be trials isn't just an emotive aspiration.

Congress can:
- Create a new court (complying w/ 6A jury vicinage)
- Give it jurisdiction over defined category of crimes
- Also create dedicated prosecutors for the same
- Strip SCOTUS of appellate jurisdiction

It can be done.

Gas Town’s Agent Patterns, Design Bottlenecks, and Vibecoding at Scale On agent orchestration patterns, why design and critical thinking are the new bottlenecks, and whether we should let go of looking at code

I have Gas Town derangement syndrome and spent the last few weeks writing thousands of words on agent orchestration patterns; how they shift our bottlenecks and force us to ask whether and when we should stop looking at code

Scaling PostgreSQL to power 800 million ChatGPT users By Bohan Zhang, Member of the Technical Staff

This blog post is a cautionary tale of the disaster that is trying to scale PostgreSQL beyond its limits.

I firmly expect to have someone cite it to me as an example of how PostgreSQL scales extremely well.
