JSON schema doesn't deal with how your language treats the underlying data - and shouldn't do it. Use custom deserializers for that.

CRUD on database rows via HTTP verbs is solved. See Postgrest/postgraphile. Most backend programmers are obsessed with constructing lousy versions of those two programs. With this said, I know I just made a few extra enemies.

Every time that I tried to implement something like this (logic/validation in DB via constraints/fks, postgraphile/postgrest in the backend, react admin/react-json-schema-forms in the frontend) all I got was new enemies.

Text files are a meh proxy for ASTs, which is what we actually write when writing programs. I want a programming language in which I can edit ASTs.

Avoiding side effects is great, it allows you to construct big programs by reasoning about the parts that make them. FP also taught me a lot about types, which allow me to define even better the parts that construct big programs.

Furthermore, this enables creating sub-contexts (like run this operation but with this different configuration) which is something almost impossible to do with DI frameworks.

Congratulations on your code! You created apiCall, effectively your own library for doing requests. The very same thing that you ought to banish. Once you have setup that library (or hook) yes, using it it's indeed 4 lines of code. Tha

I just spent most of the afternoon trying to make a government java program work. It won't apply electronic signatures. I know because it throws 47-line exception tracebacks and does nothing on the UI. Its documentation is for windows

Well, Microsoft has always been about "our stuff is first class citizen, everything else is second class citizen". You could see that in the 2000s when Microsoft claimed Windows 2003 to be multiplatform because it could run binari

Sure, after you name an example of a programming language where neither you nor someone else has to compile the dependencies for a given program.

Nothing short of linear types prevent you from saving the open file descriptor to a variable, closing the file, then using the open file descriptor variable again.

10 billion years is more than the age of the Earth. It's beyond arrogant to plan that anything that we do now will be relevant by then. After all, for more than half the last 10 billion years the Earth didn't exist yet.

Yeah, a distributed system with proofs of it working under some specific assumptions. This is the future. It's a future hard and complicated because the tools and the expertise are not here yet, but definitely the future.

Martin Kleppmann verifying distributed systems? That's as good as it can get.

Can I have the opposite? I want to be able to run webassembly-based extensions in postgresql. I don't like writing C, and most postgresql languages offer too much (no sandboxing, need slow interpreters and shit). But a WASM based sandb

That's fair. Why write html in javascript, when you can write shitty javascript in the templates (via ng-if and ng-for)?

This is a very good book that will teach you the basics of manipulating code in a correct way (correct as in mathematically correct, not in some nebulously ill-defined level of correctness). if-nest-a FTW!

Can you pattern match deeply? Can you make a case for ADD where the first param is a MULT with the second param of the MULT being INT(5)?

You can separate concerns without microservices too! People in the past were able to do it, they even invented programming language keywords for it, like https://www.tutlane.com/tutorial/csharp/csharp-access-modif
