I'm outta here. Find me on the other site, in bio.
This site is bad. Its owner is worse. It's long past time to move on, and be a happier person for it.

i don't think people understand the magnitude of rogers being down in canada.
some 911 services are out.
many PoS systems are dead.
all cellphone service is out on multiple carriers.
many finance networks (e.g. trading) are down.
many travel booking sites are down.

A gift for the Linux/Node.js perf analysis/optimization crowd! You can generate data like this:
$ npx pflames run -- node myapp.js # or any linux binary
Then you can run this to get a flamegraph in your browser:
$ npx pflames
But wait there's more!

Dunno who needs to hear this but: No, giant piles of tooling aren't _necessary_ to write JavaScript. You can still just write some code and run it in a browser or any other JS runtime.

PSA: If your Node.js library breaks asynchronous context via userland queueing or other means, fix it with AsyncResource.
In the rest of this thread, I'll show you how you can test for this, and how to fix it in easy cases.

Hello, fellow white people!
Someone called you racist? It's not a dirty word. It's a description of your actions from their perspective. Own the responsibility to change yourself.

Now that JS runtimes aim for Node.js compat, it's getting harder to tell whether your code is actually running in real Node.js, if that matters to you or your code.
You can use this to know for sure.

Some progress! Lots more work to do here, but I think I can have a draft PR ready to go by the end of the week.
That said, the main goal here is to PR it into Node.js core. Being able to load a native shared lib in Node.js without extra custom C++ glue would be fantastic, considering all the pitfalls of native addons today.

Hey Node.js folks! I made another gift for you!
Ever wish you could free() a Buffer, because you know you're not gonna use it again? The extra perf would be huge, right?
Well you can! I've wrapped up the easiest way of doing it in an npm module. Enjoy!

For some weekend recreational programming shenanigans, I made a *cursed* synchronous HTTP API for Node.js. It works, but it's incredibly slow, and just generally bad in almost every conceivable way.
Kids, don't try this at home. It's 💩. Stay in school.

Dude, no one is in their right mind these days. Global pandemic, a ground war in Europe, IPCC report telling us we have 3 years left to save the world (and that's not likely to happen), etc. Cut people slack or you'll weed out candidates that would otherwise be amazing.

I typically don't use TS in my JS projects either, but neither me nor racecar startup dude nor twitch/youtube stars should decide what language you use. Do what makes you happy and do whatever tradeoff math works for you.

PSA: Are you maintaining a Node.js library that you want folks to be able to instrument in APM tools, etc.?
Consider adding `diagnostics_channel` hooks *everywhere*. A good heuristic here is: put them everywhere there's a start or an end to some kind of operation.

Feels like I'm pretty close to wrapping up the first iteration of built-in FFI in Node.js. By far the biggest difficulty is the multitude of systems that Node.js supports.

I tested positive on thursday, finally, after like 2.5 years. So did some of my colleagues, also their first time. Stuck in a Paris hotel for the next week.
My symptoms are up and down, but overall not worse than a cold or flu.
Stay safe people! This shit isn't over yet.

The longer you write JavaScript, the more your bugs turn out to always be "forgot to return the promise".

Node.js:
* Fast builtin FFI
* More multithreaded programming primitives
* Unix domain datagrams
* Longer-term LTS
npm:
* Not having the registry controlled by a single company
* Package a build tool apart from node-gyp, like cmake.js or literally anything else.

"backend" and "frontend" are some pretty nebulous terms. avoid them if you can. instead refer to exactly what you mean, like "api server", "web server", "browser code", etc. (or better terms if you have them.)

Free idea for VCs:
You're obviously willing to throw large piles of cash at companies doing net-new open source tools. That's cool! Awesome!
But why not also fund a bunch of devs to maintain/improve the tools your portfolio companies already rely on? The benefits would be huge!

I'm finding more and more use cases for long/detailed error messages in Node.js.
What if we normalized/standardized a `detailedMessage` property containing multiline super-helpful error messages, with ANSI diagrams even.
Building support for it into test runners would be cool!

Alright so because everyone's talking about Deno:
There's a lot I like about it. There's also a lot I don't like. Same goes for Node.js.
There's room in the SSJS sphere for both, and they can both learn from each other, and even collaborate! There's nothing wrong with this!

Node.js friends in Austin: stay safe. BA.4 and BA.5 variants are particularly virulent. The pandemic is not over, and events like OpenJS world will increase spread (and increase the probability of more lethal variants) if folks aren't careful.
