📢 GORM теперь поддерживает дженерики — работа с БД в Go стала ещё проще и безопаснее!

С версии GORM v1.30.0 появилась полноценная поддержка дженериков (Go 1.18+), которая позволяет писать более выразительный и типобезопасный код без шаблонных повторов.

🔧 Пример:


ctx := context.Background()

// Создание
gorm.G[User](db).Create(ctx, &User{Name: "Alice"})

// Поиск
user, err := gorm.G[User](db).Where("name = ?", "Alice").First(ctx)

// Обновление
gorm.G[User](db).Where("id = ?", user.ID).Update(ctx, "age", 30)

// Удаление
gorm.G[User](db).Where("id = ?", user.ID).Delete(ctx)


Что это даёт:
• Типобезопасность на этапе компиляции
• Более компактный и читаемый код
• Лёгкая интеграция с OnConflict, Joins, Hints, Preload и пр.
• Улучшенный DX (developer experience)

📎 Документация: https://gorm.io/docs/the_generics_way.html

Если ты пишешь на Go и используешь GORM — самое время перейти на новый стиль.

Spiking bond yields driving sharp losses in tech stocks

A spike in interest rates since the start of the year has accelerated a rotation out of high-growth technology stocks and into value stocks poised to benefit from a reopening of the economy. The Nasdaq has fallen more than 10% over the past month as the Dow has soared to record highs, with a spike in the 10-year US Treasury yield acting as the main catalyst. It recently surged to a cycle high of more than 1.60% after starting the year below 1%. But according to Jim Paulsen, the Leuthold Group's chief investment strategist, rising interest rates do not represent a long-term threat to the stock market. Paulsen expects the 10-year yield to cross 2% by the end of the year. A spike in interest rates and its impact on the stock market depends on the economic backdrop, according to Paulsen. Rising interest rates amid a strengthening economy "may prove no challenge at all for stocks," Paulsen said.

How Does Bitcoin Work?

Bitcoin is built on a distributed digital record called a blockchain. As the name implies, blockchain is a linked body of data, made up of units called blocks that contain information about each and every transaction, including date and time, total value, buyer and seller, and a unique identifying code for each exchange. Entries are strung together in chronological order, creating a digital chain of blocks. “Once a block is added to the blockchain, it becomes accessible to anyone who wishes to view it, acting as a public ledger of cryptocurrency transactions,” says Stacey Harris, consultant for Pelicoin, a network of cryptocurrency ATMs. Blockchain is decentralized, which means it’s not controlled by any one organization. “It’s like a Google Doc that anyone can work on,” says Buchi Okoro, CEO and co-founder of African cryptocurrency exchange Quidax. “Nobody owns it, but anyone who has a link can contribute to it. And as different people update it, your copy also gets updated.”
