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.

1.18 is released
I already played around a bit wit the beta a while back and made an iterator library to get to know this new language. It's here for anyone interested: https://github.com/polyfloyd/go-iterator

iter: Generic, lazy iterators for Go 1.18
Regarding call chaining, it is still possible to chain things with operations that return different types, but they have to be done with functions instead of methods, so the result is still the same, just it's a little less readable. There is a generic iterator implementation by polyfloyd that doesn't support method chaining, but imo being able to chain iterators is one of their biggest strengths, since implementing lazy evaluation manually for a single operation isn't that difficult, its when you need to perform multiple kinds of manipulations that it gets messy.

Go 1.20.5 is released
Seems like this go runtime deadlock fix didn't get included.

If you must read the rest of this document to understand the behavior of your program, you are being too clever. Don't be clever.
Nothing new in fact, it's part of the culture. There is no "why", just "don't"s - an example among others https://github.com/golang/go/issues/45179
Not to worry, at least the Go team itself is still having trouble with its own completely uncheckable locking.

Is there a good place to find best practices?
I usually see and recommend: https://go.dev/talks/2013/bestpractices.slide#1 https://go.dev/talks/2014/readability.slide#1 https://github.com/golang/go/wiki/CodeReviewComments https://about.sourcegraph.com/blog/go/idiomatic-go https://github.com/teivah/100-go-mistakes

Why no src directory?
This mother of all things has a dedicated src directory, so it really comes down to each project to choose its own file structure.

Exploring Async PHP
There are many solutions available without requiring PHP 8.1 that have been battle tested, but it's interesting to see the direction the PHP language is going in to compete with the likes of Golang and Elixir, both of which support async programming and have done for years.

Some annoying moments in Golang
I dislike how the implicit reference-like behavior of slices, maps, channels, and function pointers confuses newcomers to the language. It would be less ergonomic to have to declare them as pointer types, but it would be more clear to readers. The language used to actually do this in its pre-1.0 infancy (example). Everything is passed by value, but the values are pointer themselves to the actual data structures.
Will change in Go 1.21

v - Simple, fast, safe, compiled language for developing maintainable software. Compiles itself in <1s with zero library dependencies. Supports automatic C => V translation. https://vlang.io
TinyGo - Go compiler for small places. Microcontrollers, WebAssembly (WASM/WASI), and command-line tools. Based on LLVM.
zig - General-purpose programming language and toolchain for maintaining robust, optimal, and reusable software.
Nim - Nim is a statically typed compiled systems programming language. It combines successful concepts from mature languages like Python, Ada and Modula. Its design focuses on efficiency, expressiveness, and elegance (in that order of priority).
