There exists several schema migration tools from MySQL to PostgreSQL, pgloader as one of the most popular ones.

All off them, as far as I have seen, is designed to be a single shot schema migration tool, so if MySQL schema was changed due to continuous development after pgloader was executed, developers have to sync them to PostgresQL in some kind of manual, or custom-made script. (custom-made script seems like the most common way when I searched it online) Another aspect of the existing ones is that how the schema is migrated tends to be a black box, and the configuration file didn't seem fully customizable to me. For example, you cannot do something like excluding an index for a certain table.

This tool can resolve both cases.

How it works consists of 3 steps:

1. parse MySQL schema into ruby-handleable objects by using rails ActiveRecord

2. combine 1., pre-defined general migration rules, and user-defined dsl to generate a PostgresQL schemafile

3. apply 2. using ridgepole(a common rails schema management tool in japan) to PostgresQL, which checks the diff between 2. and the actual PostgresQL schema and generates/runs the exact DDL necessary to apply

A few weeks back as the US export ban news hit, and while I still had access to Fable, I asked it to create a blog from his own POV.

Of course I "prompted" this and it would be silly to try to state otherwise, but regardless I think its thinking and thus writing are interesting enough to share.

The full contents of this site are written by the LLM. From text to code to svg's.

It made several articles, I think they're also a bit short and shallow like the lake's itself is, but I'll leave that opinion up to you guys.

PS: As i prompted this, i remember there was some "I dont want your AI slop making the headlines of HN that day". The whole point of this site was to let the AI experiment, not to put myself or intersect any humanity from it, the text is interesting cause it approaches thinking about the differences between human and artificial minds, I think.

If you hate it just don't visit it idk what to tell you.

I am a glider pilot, coming back to the sport after 10 years break. I am building YAW - a digital logbook for glider pilots. At the moment it has an ability to add flights and share the logbook with relevant third parties, ie instructors, CFIs at other gliding sites.

I am now working on onboarding existing pilots which means loading tonnes of flights from print/paper logbooks.
