The language of silicon dreams and stack overflows.
A precise acid-based technique for carving patterns into metal or creating circuit boards by chemically eating away at surfaces—basically letting acid do the heavy lifting while you control where the damage happens.
Data that has been scrambled using cryptographic algorithms so that only someone with the correct decryption key can read it. It's security theater that actually works, making your secrets mathematically useless to hackers.
Electrically Programmable Read-Only Memory—a type of computer chip that stores data and can be reprogrammed using high voltage, with a distinctive window that allows UV light to erase it. Common in early embedded systems and robotics.
