Hashrate is the speed of hash attempts. Miners keep trying until one hash falls below Bitcoin’s target. On average, the network finds one block every 10 minutes. #bitaxe(1.2 TH/s) shows it to you on your desk: Power in. Hashes produced. Bonus: you might find a block. #bitaxe

Ever wondered what actually happens inside a microcontroller the exact moment you apply power? πŸ€“ When you hit "compile," the IDE hides the magic. Here’s a look under the hood of an ARM Cortex-M memory layout: Before vs. After Power-Up. πŸ§ πŸ”½

πŸ”‹ AFTER POWER-UP (Active in SRAM) πŸ”Ή Copy .data: Startup logic copies initial values from Flash (LMA) to working addresses in SRAM (VMA). πŸ”Ή Zero .bss: Block reserved for uninitialized globals & explicitly zeroed out. πŸ”Ή Stack/Heap: Mapped for local vars/dynamic allocation.

⚑ THE POWER-UP SEQUENCE The moment power hits, the CPU reads the Vector Table, loads the Stack Pointer, and jumps to the Reset Handler. Before your main() function can even safely run, this startup code must do the heavy lifting to prep your SRAM. πŸ› οΈ

πŸ”‹ BEFORE POWER-UP (Resting in Flash/ROM)While powered off, firmware rests in non-volatile memory. πŸ”Ή .text: Compiled instructions & Vector Table πŸ”Ή .rodata: Read-only constants πŸ”Ή .data (LMA): Initial values of initialized globals (must survive power loss!)
