Suddenly, your beautiful, safe Rust world — with println!, threads, and files — vanishes. Welcome to the no_std world. But here’s the twist: Rust doesn’t need libc or even...")

The compiler guards your memory like a loyal knight — no use-after-free, no data races, no null dereferences. But then… you meet DMA — Direct Memory Access — a hardware-level beast that says: “I’ll just write into memory directly, thanks. No need to bother your borrow checker.” And suddenly, Rust’s guarantees start trembling. This is the story of what happens when Rust’s ownership model ...")

TL;DR New macro system: define declarative macros with the macro keyword instead of macro_rules!. Real scoping: paths inside the macro body resolve where the macro is defined, not where it’s invoked.

Something that quietly put data on the heap and cleaned it later. I could not have been more wrong. Box<T> is not a convenience. It is a contract. It turns heap allocation — one of the most unpredictable parts of system design — into something you can trust every single time. And once you see what actually happens inside that one call to Box::new(), you...")

Yes, and Here’s the Dangerous Way People Do It (Created page with "500px If you’ve spent time in Java or C#, you’ve probably seen the Singleton pattern — a way to guarantee that only one instance of a type exists in your program. It’s a design pattern that people either love (“simple global access”) or hate (“global mutable state is evil”). When I first moved to Rust, I assumed singletons weren’t even possible. After all, Rust hates global mutable state. And yet… developers still...")

(Created page with "Hook Everyone loves to chant the gospel of Rust: memory safety, fearless concurrency, no segfaults, borrow checker as your guardian angel. But here’s the truth no Rust evangelist wants on a T-shirt: Rust is only safe because of the unsafe parts. Yes. That keyword you were told to avoid like it’s black magic? That’s the engine oil.

This is the story of the tradeoffs, the tiny engineering changes that mattered, and the exact pattern that any backend engineer can reproduce on commodity hardware. 500px Why the question matters Most scaling stories are about adding mo...")

Pages crashed, graphs spiked, and the pager screamed like a fire alarm. The rewrite was calm. No alerts, no drama, no 3 A.M. messages. Now the system quietly serves ten million requests every single day — and I barely think about it. That is not bragging. It is a confession.

Shared memory concurrency forces you into a world of mutexes, race conditions, and the constant fear that somewhere, somehow, two threads are fighting over the same piece of data. The cognitive overhead becomes overwhelming. You spend more time reasoning about locks th...")
