This is my exact experience. TypeScript seemed to hit a complexity sweet spot about 5 years ago, then they just kept adding more obscure stuff to the type system. I find that understanding TypeScript compiler errors can be almost as difficult as understanding C++ template errors at times.

This is no longer remotely true. Most .NET teams I know now deploy on Linux and develop on Windows/Mac/Linux.

I'm not seeing a major problem here, you just need to install MSVC++ alongside it.

I've always been a big proponent of TypeScript, but does anyone else feel like the type system has gotten a bit too flexible? I recently had to fix some errors when upgrading packages on an old project, and it was not at all clear what was wrong by just reading the compiler output. For some errors, there were like 5-10 lines of confusing info/context, it felt like trying to understand the errors reported in template-heavy C++.

Maybe libuv? It's used by node and julia. It's not a full standard library by any means, but it would give you the event loop with async/networking/io/threading.

Sarno's work comes up periodically on HN, and I always have to chime in to say that it cured my RSI. Everything is still completely, 100% cured at 15+ years. As a developer, I have no idea what I would have done without it, my career would have been over. Here are my previous comments:

New comment by rlp in "Ask HN: What exactly is a mindfulness meditation?"

rlp — Sun, 03 Jul 2022 09:34:57 +0000

No need for a meditation myth at all, absolutely. It's brain hacking as far as I'm concerned.

As for concentration training vs mindfulness meditation, I do think there's a difference. Concentration is a tight single-pointed focus, while mindfulness is a broad focus on the present moment. I found mindfulness meditation basically impossible without practicing concentration meditation extensively first, my mind was too overactive to settle in the present without an anchor to focus on.

It's about training your mind's executive control/function. You learn to focus on one thing and allow others to pass through your awareness without them being overly distracting/disturbing.

Think of your focus like a spotlight. Most people have very little control over their spotlight and it gets aimed at whatever is the latest thing to enter their awareness: a thought, a sound, another thought, a visual, etc. It's bouncing all around, all the time. A proficient meditator can more effectively control where the spotlight points. Over time, as the mind slowly learns to do this better, the stuff outside the spotlight fades and become less intrusive. This leads to increasing states of calm and peacefulness which extend even after the meditation session ends.

New comment by rlp in "WebAssembly 2.0 First Working Draft"

rlp — Wed, 20 Apr 2022 00:11:48 +0000

Also, WebAssembly can't support most GC runtimes now, because you can't scan the stack for roots. You can keep your own shadow stack on the heap, but that has a bunch of pretty bad performance implications. This actually impacts C/C++/Rust codegen as well, since they can't create references/pointers to anything on the stack, and have to build their own shadow stack (I think this is done in binaryen or LLVM itself?). I understand it's a security thing to disallow direct stack access, but most languages and runtimes expect it.

Anyways, that's why there needs to be support in WebAssembly for GC, because there needs to be a safe way to walk the stack (aside from the obvious JS interop considerations).

Very cool! I'd love to see proper macros in a major language like Dart. And the proposal looks good, like a mix of Scala and Nemerle.

Any particular reason you like Dart so much? I tried it briefly, and it felt like a watered-down mashup of Java and C# with somewhat worse performance.

It highly depends on the use case. When people interact with a piece of software all day every day, they tend to appreciate having more information/actions available at a glance. Simple interfaces are better for casual users, but they generally mean more clicking around and tend to be slower to use for experts.

That's great! Like you, it did take me a while to get to 100%. Old habits die hard, I guess. You really know you're there when you realize you forgot to think about RSI for a whole week/month/whatever.
