Dear AI Community,. have you solved polishing PDFs?. Is there an AI capable of.- processing user generated PDFs.- re-arranging texts, considering line breaks, paragraphs,. The goal is to re-arrange texts to "look nicely" (not split up sections if possible, etc.).

Smooth and beautiful! I love it :). The ecosystem of @elixirlang is getting better and better by the day! 🧡.

If you want to find problems in your network setup, what tools do you usually use?. - is there a problem in the local network (router, WLAN,. ).- is there a problem with the connection from the router/modem to the external web?. .

Might come in handy for you @livebookdev devs :). "pbcopy for Livebook". Here's the code for you in a handy gist: . Kudos to @sheharyarn 🤝 (

Go to the "Console" of your @elixirlang service. Connect to `iex`:. ```.bin/<application_name> remote.```. You're in!. You now have the same options as in `iex` locally, but you're in your production service (caution! :)). Copy & paste the code from Livebook and profit 🥂

We are using @digitalocean Apps. Our stack is pretty simple. We're a small team. DO Apps manages the service for us and we can sleep :). The cool thing also: they offer a "console" to connect to your services. That's what I used to connect to our @elixir service in production!.

Draft the code you need. Use modules and functions from the service you are connected to. After it works, lets apply all of it to production where the migration actually needs to be performed.

I knew I had all the moving parts already built in our codebase. However, the service did not offer the particular "feature" (=one off migration) as a simple function. So. Livebook to the rescue!. Connect @livebookdev with your app locally:.
@livebookdev One cool thing:. Connect Livebook with your actual application. Then, access code from that application 🙌. ```.# Generate random cookie value.openssl rand -hex 32. # Copy value, change <cookie_value>.iex --sname realword-service --cookie <cookie_value> -S mix phx.server.```

A tech stack that keeps on giving! 🤠. I had to do a "one off migration". Once again, @elixirlang, @livebookdev and @digitalocean made things easy. Here's how 👇🧵

When you need to add a list of countries to your project, how do you go about this?. What do you use?. I'd also need to distinguish between EU countries and non-EU countries.

Just another example of how the @AshFramework saved us a lot of time 🤝. Btw. here's the official guide, if you want to learn more about Calculations, including a nice video! 📹.

All the data was already stored somewhere, just not the way I wanted it to expose to the GraphQL API. Through the calculation, I could do just that and also "hide" business logic. The API client does not need to care how the data is crunched.

In my real-life example, I had to fetch items for a "travel plan" (think, fetch hotels, flights,. ). Each item had prices. I had to group the items a certain way. For each group, I had to sum numbers (selling prices, sales taxes,. ).

And here comes the magic ✨. The implementation of the "Calculation" that returns a list of Profile resources. You can play with your imagination and do lots of things here. In this example, we pretend to have all the data already and just put them in the shape we need.

Here's what a Profile looks like. It is not a materialized resource (not stored in DB). It's an embeded one that, in this case, only lives for a short time in memory when reading `author.profiles`. It provides the shape we want to work with. An easy to consume data structure.
