pointfree.io VS flyctl

You can test out things like that at https://pointfree.io. It takes a lambda with all the arguments present, like \ a b c -> f (g a b c), and it produces ((f .) .) . g.

I'm learning Haskell, coming from the APL family. I'm familiar with point-free style and function composition and wanted to learn Haskell for a more pure functional experience. To get some practice i figured I'd write up the dot product and vector product functions. I haven't begun looking at the vector product, but for dot product I quickly came to `dot a b = sum $ zipWith (*) a b`. After toying around with composition (the B-combinator .), I couldn't get it to work. I looked up the tacit solution in pointfree.io, and it gave me the short and sweet `dot = (sum .) . zipWith (*)`. Now here's my question: how is (sum .) supposed to work? I don't get where the arguments implicitly go or how this makes syntactically sense. What is the order of operations?

Pointfree sort of does that https://pointfree.io/

This is great! And timely too, since http://pointfree.io seems to be down at the moment. It’s also nice to see that the WASM backend is already usable.

The source code seems to be here: https://github.com/keathley/pointfree.io

To begin with, you could go with a Platform-as-a-Service (PaaS) provider like Heroku, or Fly for a more seamless experience. You can also do a bit of DevOps: set up a Docker installation on a VPS and deploy your app there.

To begin visit fly.io to create an account. Next install flyctl a command line tool for creating and deploying fly apps. macOS

For frontend deployment, I used Netlify (for the generous free package) and the recommended fly.io for server + database (also cheap package).

Create an account on Fly.io.

You can learn more about fly.io and tigris, we will need to create an account on both platforms for this project regardless. Anyway with the theory out of the way let's get started in the next section as we create our accounts and start building the app.

Fly.io is a platform that helps you run your apps and databases closer to your users all around the world. It takes your app code, packages it up neatly, and puts it on virtual machines that can be quickly started or stopped. This makes your app faster for users and more reliable. Fly.io is easy to use, works well for small projects or personal apps. It's a great way to make sure your app runs smoothly for people no matter where they are.

In this post, we'll start from scratch, running FerretDB locally via Docker, trying out the connection with mongosh and the MongoDB Node.js client, and finally deploy FerretDB to Fly.io for a production ready set up.

Fly is a cloud platform that focuses on global edge computing. Fly specializes in high-performance hosting and provides a global network of edge locations. Fly is known for its scalability and performance optimizations.

But videototextai.com is built using NextJS + Firebase auth + Firestore and a backend deployed at fly.io . Fly makes it really easy to deploy docker containers and that is IMO the fastest way to develop, you can setup a local setup
