lt-app VS walex

Shout out for an app called Language Transfer that I just came across via Reddit (https://www.languagetransfer.org/). It teaches languages speaking first through a simple audio course. Developed by one guy, completely free and without ads, but from what I’ve seen so far has a very clear focus on quickly getting up to speed with a different angle than other courses.

This is the basic idea behind the Language Transfer series of courses - https://www.languagetransfer.org/

I highly recommend www.languagetransfer.org. He teaches key grammar in a very thoughtful way.

googled it and got https://www.languagetransfer.org/. I assume thats what you were referring to. Can you please share why you recommended that program in particular over others?

Language Transfer has free audio courses for the languages you listed. I did the spanish course and some of the italian. It's honestly the best and most comprehensive audio course I've ever come across. It got me from nada to being able to effectively communicate and understand spanish (albeit with a limited vocabulary). It's heaps better than luodingo!

The guy behind Language Transfer, u/LanguageTransfer, one of the best language learning resource for Spanish, is from Cyprus. I’m not sure whether from the Greek or Turkish side though.

The WAL CDC approach: https://github.com/cpursley/walex?tab=readme-ov-file#publica...

CREATE PUBLICATION news_item FOR TABLE news WHERE (topic IS "AAPL");

What do you mean testing with processes?

I won't suggest these are the best written tests, but I test various processes, supervisors, etc like this:

You don’t send the entire WAL, just what you subscribe to - and you can even filter via SQL: https://github.com/cpursley/walex?tab=readme-ov-file#publica...

What we do is much if the business logic in Postgres. But then there’s all the other stuff like external integrations, etc.

We handled that by having an Even system built on the Postgres WAL that we use like a callback system.

I put together a little library in Elixir (that originally started out as forked Supabase realtime) for this:

Recently added the ability to configure WalEx to forward events to webhooks or EventRelay (so you don’t need to know Elixir).

If you're using Elixir, check out https://github.com/cpursley/walex

I've actually been thinking about turning this idea into a product where you can just point it at your postgres database and select the tables you want to listen to (with filters, like you describe). And have that forwarded to a webhook (with possibility of other protocols).

I'd love to hear folks thoughts on that (and if it would be something people would pay for).

Neat, this is the pattern I've been thinking about for a while now. Also glad to see this is Elixir based.

I've been using https://github.com/cpursley/walex (basically a fork of cainophile via a fork for subabase) to listen to Postgres changes in Elixir.

Which is based on WAL logs and doesnt have the same limitations.

Great writeup, just added this to the WalEx readme:

https://github.com/cpursley/walex

(WalEx is an Elixir lib for listening to the WAL and perform callback-like actions with the data)

Very cool.

I'm using Elixir to listen to change events via https://github.com/cpursley/walex (which I basically ripped off from Supabase).
