Идемпотентность — звучит сложно, говорят о ней редко, но это касается всех приложений, использующих API в своей работе. Меня зовут Денис Исаев, и я руковожу одной из бэкенд групп в Яндекс Такси. Сегодня я поделюсь с читателями описанием проблем, которые могут возникнуть, если не учитывать идемпотентность распределенных систем в своем проекте.

This brief highlights key statistics on men’s health. Men face significant health challenges, including shorter life expectancies, high suicide rates, and substantial losses due to drug overdoses and COVID-19. Despite these issues, there aren’t many public health goals that target men, and only one male-specific preventive measure is covered by the ACA. These facts underscore the need for focused attention on men’s health.

In XDSD everybody is motivated to produce tangible and meaningful results. That's why we don't use emails, Skype, HipChat or phone calls.

For me, this imagined audience is more important than getting it right. Which is why I write my blog posts with the wiki spirit. All these sites are pretty similar, in essence. Blog, wiki, digital garden, Zettelkasten, there’s not enough difference to draw lines. It’s all a question of intent, of culture, of belonging. The blog spirit is to write pages over time, and they disappear into the archive. The digital garden spirit is to write unfinished articles and papers, to be refined or not. The Zettelkasten spirit is to follow the trail of thoughts you thought and add new branches, small notes with new thoughts leading to more thoughts on new notes. And the wiki spirit is to write and edit online, to hit the Save button and then it’s live. There is no editor, there is no draft. Wiki is like brutalism in content management. I can see the page sources and the end result is obvious and full of that old web power. It’s not an app. The software has no idea of process. The wiki spirit is to open that window, write the text and hit save. And then I read it again, and edit it. And tomorrow, I read it again, and edit it. And next week, perhaps, I read it again, and edit it.

I no longer live in the Wiki Now. The pages are intended for future readers but they are not timeless. I add timestamps all over the place. The blog spirit is strong. The pages do disappear into the great compost of thoughts. The archive gobbles them up. I do go back but I don’t rewrite the pages completely. I’m more likely to simply add a timestamp and some thoughts like I did on this page.

package src

type config struct {
    // Required
    foo, bar string

    // Optional
    fizz, bazz int
}

// Each optional configuration attribute will have its own public method
func (c *config) WithFizz(fizz int) *config {
    c.fizz = fizz
    return c
}

func (c *config) WithBazz(bazz int) *config {
    c.bazz = bazz
    return c
}

// This only accepts the required options as params
func NewConfig(foo, bar string) *config {
    // First fill in the options with default values
    return &config{foo, bar, 10, 100}
}

func Do(c *config) {}

You’d use the API as follows:

package main

import ".../src"

func main() {
    // Initialize the struct with only the required options and then chain
    // the option methods to update the optional configuration attributes
    c := src.NewConfig("hello", "world").WithFizz(0).WithBazz(42)
    src.Do(c)
}

GQL is a query language with a syntax very similar to SQL with a tiny engine to perform queries on .git files instance of database files, the engine executes the query on the fly without the need to create database files or convert .git files into any other format, note that all Keywords in GQL are case-insensitive similar to SQL.
