Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Best practice for separating DB models from API models?
When the internal model and the API model are pretty much the same, you might simply copy the result from one struct to another using e.g. https://github.com/jinzhu/copier

sqlc patterns in production
An alternative is to use a reflection based struct copier library or a codegen struct copier library

Generating a YAML file with Go template engine?
I think using the yaml library directly would be a lot easier. You could then unmarshal both configs to a struct and use something like copier to update the values.

how do you deep copy a struct with slice of structs to another
However, if you don't want to bother, I suggest to take a look at https://github.com/jinzhu/copier which is more extensive and works with slices and pointer types.

Show HN: Riza – Safely run untrusted code from your app
Hi HN, I’m Kyle and together with Andrew (https://news.ycombinator.com/user?id=stanleydrew) we’ve been working on Riza (https://riza.io), a project to make WASM sandboxing more approachable. We’re excited to share a developer preview of our code interpreter API with HN.
There’s a bit of a backstory here. A few months ago, an old coworker reached out asking how to execute untrusted code generated by an LLM. Based on our experience building a plugin system for sqlc (https://sqlc.dev), we thought a sandboxed WASM runtime would be a good fit. A bit of hacking later, we got everything wired up to solve his issue. Now the API is ready for other developers to try out.
The Riza Code Interpreter API is an HTTP interface to various dynamic language interpreters, each running inside a WASM sandbox without access to the outside world (for now). We modeled the API to align with a POSIX shell-style interface.
We made a playground so you can try it out without signing up: https://riza.io
The API documentation lives here: https://docs.riza.io
There are many limitations at the moment, but we expect to rapidly expand capabilities so that programs can e.g. access the network and filesystem. Our roadmap has more details: https://docs.riza.io/reference/roadmap
If you need to execute LLM-generated code we’d love to have you try the API and let us know if you run into any issues. You can email us directly at [email protected].

"Is there a way to get sqlc to use pointers for nullable columns instead of the sql.Null types?"

Show HN: Sqlbind a Python library to compose raw SQL
I came across this yesterday for golang: https://sqlc.dev which is somewhat like what you want, maybe.
Not sure it allows you to parameterize table names but the basic idea is codegen from sql queries so you are working with go code (autocompletion etc).

ORMs are nice but they are the wrong abstraction
Agreed, but tools like https://sqlc.dev, which I mention in the article, are a good trade-off that allows you to have verified, testable, SQL in your code.

Go ORMs Compared
sqlc is not strictly a conventional ORM. It offers a unique approach by generating Go code from SQL queries. This allows developers to write SQL, which sqlc then converts into type-safe Go code, reducing the boilerplate significantly. It ensures that your queries are syntactically correct and type-safe. sqlc is ideal for those who prefer writing SQL and are looking for an efficient way to integrate it into a Go application.

Type-safe Data Access in Go using Prisma and sqlc
I was browsing awesome-go for ideas on how to setup my data access layer when I stumbled on sqlc. It seemed like a great option. Code generation is a strategy often used in the Go ecosystem and making my queries safe at compile time was an idea I really liked. Knex was great, but it required of me that I test thoroughly my queries at runtime and that I sanitize my query results to ensure type safety within my application.
