Understand Pointers, simple and easy with Go

Lidar com ponteiros pela primeira vez assusta quem vem de linguagens como JavaScript, Python ou Java, onde a gestão de memória é automática Mas a ideia é mais simples do que parece.

• Pointers are variables holding memory addresses of other variables, not their values.
• In Go, pointers are declared using the & operator, e.g., &x for a variable x.

Anonymous pastebins are a spam magnet. I gated mine with proof-of-work instead of logins.

Open pastebin, no login, paste text, get a link. That is the whole appeal, and it is also why every anonymous paste service turns into a dumping ground.

• Anonymous pastebins become spam magnets due to bot scripting.
• Proof-of-work replaces logins, CAPTCHAs, and IP rate-limiting.
• Node.js script demonstrates hashing and posting with proof-of-work.

• LazyPromise offers promise-like API while maintaining Observable features
• Supports cancellation via AbortController API, unlike native Promise
• Runs constructor callback on each subscription, similar to single-shot Observable
