Порекомендовали познавательный сайт с перечнем принципов, которые могут пригодиться разработчику. Среди них приводится закон Вадлера:

In any language design, the total time spent discussing a feature in this list is proportional to two raised to the power of its position.
    0. Semantics
    1. Syntax
    2. Lexical syntax
    3. Lexical syntax of comments

То есть, каждый последующий пункт в списке будет занимать в 2 раза больше времени, чем предыдущий - больше всего времени уйдет на лексический синтаксис комментариев. Примечательно, что впервые этот закон появился при обсуждении очередной языковой фичи языка Haskell больше 25 лет назад, уже тогда подтвержденный "многочисленными эмпирическими наблюдениями".

Приятно видеть, что при разработке Dotty закон Вадлера смогли обойти - на форуме контрибьюторов едва ли можно найти пост, посвященный комментариям. Тем не менее, судя по тому же форуму, имеет место "закон Одерского", в котором место лексического синтаксиса комментариев занимают изменения, связанные с implicit-параметрами.

Encrypted messaging app Telegram has announced that it is rolling out a new update that gives users more ways to use new emojis to express how they are feeling -- with infinite reactions and emoji statuses. The company said that premium users can pick reactions from an infinite selection of custom emojis. To make choosing from thousands of emojis easier, they can now attach up to three reactions per message.

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.
