Наконец-то дошли руки присоединиться к хабра-сообществу: опубликовали мой перевод поста Луки Якобовича "A tale on semirings".

Я выбрал для перевода именно этот пост, поскольку мне очень понравилась наглядность примера - переложение структуры абстрактной алгебры (полукольцо) и связанных с ней законов на код, понятный даже не знакомому со Scala человеку. В дополнение к этому показывается, как можно перенести концепцию полукольца на типы высшего порядка. И всё это с отсылками на классы cats - одной из наиболее используемых в Scala ФП-библиотек.

Надеюсь, вам понравится как мой перевод, так и сам пост Луки. Несмотря на сравнительно большой объём, материал интересный и изложен достаточно подробно.

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.
