⚙️ proposal: cmd/go: add support for dealing with flaky tests или работа с «капризными» тестами.

Нестабильные тесты – настоящий бич мира разработки ПО. Для тех немногих счастливчиков, кто не в курсе: "flaky tests" – это тесты, которые проходят или не проходят в зависимости от фазы луны. При повторном запуске такой тест, как правило, успешно проходит (как и при всех последующих попытках). В идеальном мире таких тестов в проекте быть не должно по определению. Однако реальность такова: такие тесты есть почти везде. Они есть у вас в проекте, они есть в Tailscale (где даже написали специальный враппер для работы с ними), они есть и в компиляторе Go.

Брэд Фитцпатрик предлагает решить эту проблему на уровне туллинга для языка. Вы помечаете тест как flaky, и go test автоматически понимает, что его нужно повторить (возможно, несколько раз) в случае ошибки. Предложение еще находится на ранних этапах обсуждения, поэтому у вас есть возможность поучаствовать и предложить свои идеи.

Can I mute a Telegram group?

In recent times, Telegram has gained a lot of popularity because of the controversy over WhatsApp’s new privacy policy. In January 2021, Telegram was the most downloaded app worldwide and crossed 500 million monthly active users. And with so many active users on the app, people might get messages in bulk from a group or a channel that can be a little irritating. So to get rid of the same, you can mute groups, chats, and channels on Telegram just like WhatsApp. You can mute notifications for one hour, eight hours, or two days, or you can disable notifications forever.

Telegram Q&A

Q: How does hottg.com work?

Once you've set up a username, you can give people a hottg.com/username link. Opening that link on their phone will automatically fire up their Telegram app and open a chat with you. You can share username links with friends, write them on business cards or put them up on your website.This way people can contact you on Telegram without knowing your phone number.

With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences. You can write to your phone contacts and find people by their usernames. As a result, Telegram is like SMS and email combined — and can take care of all your personal or business messaging needs. In addition to this, we support end-to-end encrypted voice calls.
