⚙️

Bitmasks use individual bits as boolean flags. Convert a decimal mask (e.g. 12 = 0b1100) to binary to see which bits are set.

💡

Unix permissions: 7 = 0b111 (rwx), 5 = 0b101 (r-x), 4 = 0b100 (r--). Convert each permission digit to see what it means.

🔢

Power of 2 check: a number is a power of 2 if its binary representation has exactly one 1 bit. The grouped binary display makes this obvious.

📊

Signed vs unsigned: 255 in 8-bit unsigned = 0xFF. As a signed byte, values 128–255 are negative. The bit pattern (11111111) is the same.
