MacOS issue — a lot of purgeable disk space

I used to have an issue — about 300Gb of extra disk space occupied on my MacBook labeled as «pergeable» (on my MacOS Sonoma). There are a lot of suggestion on the internet, but only 2 of them worked for me. First, I synced my backups with 2 of my TimeMachines (one of them was …

Golang’s sync.Map internals

Great article on the topic — https://victoriametrics.com/blog/go-sync-map/index.html. The whole series of articles is solid, so please take a look if you are interested. Let me share the most important insights. How it works Internal structure is:

type Map struct {
	mu Mutex
	read atomic.Pointer[readOnly]
	dirty map[any]*entry
	misses int
}

type Map struct {

mu Mutex

read atomic.Pointer[readOnly]

dirty map[any]*entry

misses int

}

MVC, MVP, MVVM, MVVM-C, and VIPER architecture patterns comparison

Great diagram comparing MVC, MVP, MVVM, MVVM-C, and VIPER architecture patterns from ByteByteGo: They also provide the following description: — MVC, the oldest pattern, dates back almost 50 years — Every pattern has a «view» (V) responsible for displaying content and receiving user input — Most patterns include a «model» (M) to manage business data …

Cleanlinter — my first golang linter

I’ve implemented my first go linter, called cleanlinter — https://github.com/bullgare/cleanlinter. It’s a simplistic linter to check golang project internal imports according to Clean Architecture pattern. Installation

go install github.com/bullgare/cleanlinter/cmd/cleanlinter@latest

1	go install github.com/bullgare/cleanlinter/cmd/cleanlinter@latest

Usage

cleanlinter \
-cleanlinter_path_to_domain=github.com/bullgare/cleanlinter/test/testdata/src/project_correct/internal/domain \
-cleanlinter_path_to_usecase=github.com/bullgare/cleanlinter/test/testdata/src/project_correct/internal/usecase \
-cleanlinter_path_to_adapter=github.com/bullgare/cleanlinter/test/testdata/src/project_correct/internal/adapter \
-cleanlinter_path_to_infra=github.com/bullgare/cleanlinter/test/testdata/src/project_correct/internal/infra \
./...

cleanlinter \

-cleanlinter_path_to_domain=github.com/bullgare/cleanlinter/test/testdata/src/project_correct/internal/domain \

-cleanlinter_path_to_usecase=github.com/bullgare/cleanlinter/test/testdata/src/project_correct/internal/usecase \

-cleanlinter_path_to_adapter=github.com/bullgare/cleanlinter/test/testdata/src/project_correct/internal/adapter \

-cleanlinter_path_to_infra=github.com/bullgare/cleanlinter/test/testdata/src/project_correct/internal/infra \

./...

To be honest, writing proper integration tests made much more time than just writing the linter.
