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.

Help with setting up Ben Johnson's wtf repo locally
I am new to go. Found wtf dial - ( https://github.com/benbjohnson/wtf ) while looking to get some project based learning. This looks pretty interesting but when I did git clone of the project my vs code is giving number dependency related problems like below.

Educational Codebases
There are a few Go projects meant to be learned from:
- https://github.com/pion/opus for to learn audio
- https://github.com/benbjohnson/wtf for overall production quality
- https://github.com/upspin/upspin difficult to explain, personally I'm not a fan of the errors
- Ben Johnson's WTF project layout: interface usage
- Exemple of Web API written in Go that you'd consider high quality

Directory structure for a golang project
I read about https://github.com/benbjohnson/wtf and the connected blog here a couple of times. Seems quite good.
- Project structure - I often see duplicate function names in db layers, why?
-
The one-and-only, must-have, eternal Go project layout
Personally I think the method is the layered architecture approach. Example: https://github.com/benbjohnson/wtf

Examples of Good Go Repos

Examples of an idiomatic API project
https://github.com/benbjohnson/wtf This repo serves as an example and fits Go very well in my opinion. Check the discussions on the repo and the blog posts.
- what do you use for migrations? or how do you the sql tables and seeding?

Setting up a Database Driver, Repository and Implementation of a transaction function for your Go App
Sometimes, backend developers tend to opt for an ORM library because it provides an abstraction between your app and the database and thus there is little or no need to write raw queries and migrations which is nice. However, if you want to get better at writing queries (SQL for example), you need to learn how to build your repositories without an ORM. To open a database handle, you can either do it directly from the database driver or do it from database/sql with the driver passed into it. I will be opening the connection with database/sql together with pgx which is a driver and toolkit for PostgreSQL. Walk with me.

The DDD Hamburger for Go
The infrastructure layer contains the concrete implementation of the repository domain interface ActivityRepository in the struct DbActivityRepository. This repository implementation uses the Postgres driver pgx and plain SQL to store the activity in the database. It uses the database transaction from the context, since the transaction was initiated by the application service.

Building RESTful API with Hexagonal Architecture in Go
For building the RESTful Point of Sale service API, I've considered and selected a combination of technologies that would work seamlessly together. For handling HTTP requests and responses, using the Gin HTTP web framework would make sense because I think it seems complete and popular among Go community too. To ensure data integrity and persistence, I'm using PostgreSQL database with pgx as the database driver, the reason I choose PostgreSQL because it is the most popular relational database to use in production and offers efficient Go integration. I'm also implementing caching using Redis with go-redis client library, which provides powerful in-memory data storage capabilities.

Working with postgres in GO.
If you are willing to commit to working only with Postgres, I highly recommend pgx. Be sure you get the latest version github.com/jackc/pgx/v5. This gives you the full power of interacting with Postgres without going through an intermediate lowest-common-denominator library.

How to Use Iris and PostgreSQL for Web Development
It uses pg package and pgx driver under the hood.

Could I get a code review?
Starting off, is there any reason you're calling out to the CLI, instead of just using a Postgres driver like pgx? Shelling out to the command line should always be a last resort where possible as a software engineer.

Why elixir over Golang
For maintaining state I use PostgreSQL. Driver: https://github.com/jackc/pgx (I use the pgxpools) Along with Sqlc for generating database models and allowing me to focus on just building queries in DBeaver. https://sqlc.dev/

Make psql display settings on login
An example of what I'm looking for can be found here https://github.com/jackc/pgx/wiki/Getting-started-with-pgx-through-database-sql/c9f798b4d9a500fcf93931df2464af969d68f516

Zig now has built-in HTTP server and client in std
Except pgx recommends using their native interface, not database/sql, for performance and extra features [0], so it's not that simple in practice.
