garbage collection

Intermediate 💻 Tech / IT

Definition

An automatic memory management process that cleans up unused objects so programmers don't have to. It's like having a roommate who actually takes out the trash, except it occasionally pauses your entire application to do it.

Example Usage

The app freezes for a second during garbage collection when the heap gets full—we might need to tune the GC parameters.

Origin

Invented by John McCarthy for Lisp in 1959, one of the oldest concepts in computer science still in daily use

Fun Fact

Java developers love to hate garbage collection pauses, C++ developers love to hate having to manage memory manually, and everyone agrees the other side has it worse.

virus

A microscopic piece of malicious code that spreads through computer systems like gossip through an office, corrupting files and causing IT departments to justify their existence. Unlike biological viruses, these digital parasites are deliberately created by humans who apparently have nothing better to do than ruin everyone's Tuesday. They require a host program to replicate and typically announce their presence by making your computer behave like it's possessed.

deployed

The terrifying moment when code or systems are pushed from the cozy safety of a test environment into the chaotic wilderness of production where real users can break everything. In military terms, it means sending troops into action; in tech, it means sending developers into a state of anxiety. Either way, something's probably going to explode.

proxy

An intermediary server that stands between your computer and the internet, acting as a middleman for requests and responses.
