chapel VS Gatsby

Thanks, @subharmonicon!

While Chapel can run on many different systems, the main goal is making HPC programming much easier. Therefore, we are currently focusing on hardware that you can find in HPC systems (NVIDIA, AMD and Intel). Metal doesn't fall into that category, unfortunately. So far, the name came up infrequently in our discussions IIRC (especially targetting SPIRV), but we haven't heard from any [potential] user who may be interested in it. I would encourage you or anybody else interested in it to create an issue asking for the feature: https://github.com/chapel-lang/chapel/issues/new. Seeing public interest in that direction can change our prioritization.

One thing that I wanted to add that's not in the blogpost is the "cpu-as-device" mode. With that mode, you can use any machine, even one without a GPU, to write applications using Chapel's GPU features. That mode is for those who want to do initial development/debugging on their personal laptops before putting their application on an HPC system. In other words, while you can't use Metal directly, you can still write GPU-enabled applications in your Mac using Chapel, if the end goal is to run it on an HPC system. More details on cpu-as-device: https://chapel-lang.org/docs/main/technotes/gpu.html#cpu-as-...

Agreed. Here is a serious contender[0] minus all the hype and the $100M in VC money. You would expect a minimum of interest given how Mojo is received by the community, but not really in practice.

Cray is pushing their own language as well, Chapel.

As for Julia on Cray,

"Julia — The Newest Petaflop Family Language We Have Started to Love"

> Julia is one of the few languages that are in the so-called PetaFlop family; the other languages are C, C++ and Fortrant. It achieved 1.54 petaflops with 1.3 million threads on the Cray XC40 supercomputer.

https://chapel-lang.org if possible, Nix was also recently mentioned in Chapel Workshop https://chapel-lang.org/CHIUW2023.html https://github.com/twesterhout/nix-chapel

See Val for a possible step into that direction.

Or how the Chapel language for HPC is going at it,

https://chapel-lang.org/

I suggest posting to a PLT focused resource, such as http://lambda-the-ultimate.org/

That said, a bit confused about the languages you reference in this context (Python, C#, JS) - didn't see any mention here or at your github repo of languages (some relatively ancient) in this space designed.

We needed the implicit conversion to `uint` in order for the overload resolution rules to make reasonable choices when faced with binary overloads for all of the numeric types. The document I linked talks through the examples. The case we were facing is something that we shared with `C#` -- in `C#` terms, if I make overloads for `f` for all numeric types (see https://github.com/chapel-lang/chapel/blob/main/test/types/coerce/allNumericsBinary.cs if you want to know exactly what I am talking about), then `f( myInt, myUlong )` runs `f(float, float)` which makes no sense. Especially if you care about numerical accuracy or program performance.

The first time I started building static websites is when I discovered Gatsby. I built several projects using Gatsby and hosted it on Netlify free tier. It felt like a really robust architecture and I loved that it was free.

A Gatsby site uses Gatsby, which leverages React and GraphQL to create fast and optimized web experiences. Gatsby is often used for building static websites, progressive web apps (PWAs), and even full-blown dynamic web applications.

While Next.js is a powerful framework for building server-rendered React applications, it's not the only option for developers looking to create high-performance websites. One notable alternative is Gatsby, a static site generator that leverages React and GraphQL.

The other piece of important information to acknowledge here is that when we say RSCs need a framework, “framework” effectively just means “Next.js.” There are some smaller frameworks (like Waku) that support RSCs. There are also some larger and more established frameworks (like Redwood) that have plans to support RSCs or (like Gatsby) only support RSCs in beta. We will likely see this change once we get React 19 and RSCs are part of the Stable version. However, for now, Next.js is currently the only framework recommended in the official React docs that supports server components.

GatsbyjsCMS - Gatsby is the fast and flexible framework that makes building websites with any CMS, API, or database fun again. Build and deploy headless websites that drive more traffic, convert better, and earn more revenue!

GatsbyJS

Babel plugins are everywhere. From being used to remove unwanted exports from files in Gatsby to being used to disallow users from doing re-exports in Nextjs.

In terms of GitHub stars, SSGs like Next.js, Hugo, Gatsby, Docusaurus, Nuxt.js, and Jekyll top the list. Some popular SSGs even host conferences and workshops, providing resources and networking opportunities for those looking to explore more advanced topics in depth.

Flexibility : Developers have complete control over the frontend so they can use their preferred tools and frameworks like React, Next.js, Gatsby, or Remix.
