Hero

A hero (masculine or gender-neutral) or heroine (feminine) (Ancient Greek: ἥρως, hḗrōs) is a person or main character of a literary work who, in the face of danger, combats adversity through impressive feats of ingenuity, bravery or strength, often sacrificing his or her own personal concerns for some greater good.

The concept of the hero was first founded in classical literature. It is the main or revered character in heroic epic poetry celebrated through ancient legends of a people; often striving for military conquest and living by a continually flawed personal honor code. The definition of a hero has changed throughout time, and the Merriam Webster dictionary defines a hero as "a person who is admired for great or brave acts or fine qualities". Examples of heroes range from mythological figures, such as Gilgamesh, Achilles and Iphigenia, to historical figures, such as Joan of Arc and Gandhi, to modern societal heroes like Rosa Parks.

Etymology

The word hero comes from the Greek ἥρως (hērōs), "hero, warrior", particularly one such as Heracles with divine ancestry or later given divine honors. (literally "protector" or "defender") Before the decipherment of Linear B the original form of the word was assumed to be *ἥρωϝ-, hērōw-; R. S. P. Beekes has proposed a Pre-Greek origin.

Deadlock

In concurrent programming, a deadlock is a situation in which two or more competing actions are each waiting for the other to finish, and thus neither ever does.

In a transactional database, a deadlock happens when two processes each within its own transaction updates two rows of information but in the opposite order. For example, process A updates row 1 then row 2 in the exact timeframe that process B updates row 2 then row 1. Process A can't finish updating row 2 until process B is finished, but process B cannot finish updating row 1 until process A is finished. No matter how much time is allowed to pass, this situation will never resolve itself and because of this, database management systems will typically kill the transaction of the process that has done the least amount of work.

In an operating system, a deadlock is a situation which occurs when a process or thread enters a waiting state because a resource requested is being held by another waiting process, which in turn is waiting for another resource held by another waiting process. If a process is unable to change its state indefinitely because the resources requested by it are being used by another waiting process, then the system is said to be in a deadlock.

Geometry Dash

Geometry Dash is a 2013 mobile game and Steam game developed by Sweden-based developer Robert Topala, and published by his own company RobTop Games. It is a rhythm-based running game which currently has 20 levels. Each level features unique background music. Although the player is not required to complete a level to advance to the next, they increase in difficulty for the most part. Other features of the game that exist in the latest versions are a level editor, map packs, user-created levels, secret coins, user coins, a secret vault and a great variety of icons and game modes.

Gameplay

Geometry Dash uses a simple tapping/clicking system to control different vehicles that react when a player presses anywhere on the touchscreen (space/up key(s) or mouse if playing on the Steam version) and can be held down to constantly interact (on some vehicles). Users cannot control the speed at which the icon is moving, unless it interacts with a speed changing portal. The timing and rhythm are key parts of the game.
