## Hacker conferences

A hacker conference, also known as a hacker con, is a convention for hackers. These serve as meeting places for phreakers, hackers, and security professionals.
The actual events, time-spans, and details of various themes of these conventions not only depends on the specific convention attended but also its perceived reputation. Typically the actual details of any given convention are couched in mild secrecy due to the legality of certain panels, as well as the willingness of attendees to explain themselves to law enforcement and less computer-savvy individuals (see hacker definition controversy).
Common topics include wardriving, lockpicking, corporate and network security, personal rights and freedoms, new technologies, as well as general 'geek' motifs. Some may also have contests and general collaborative events such as hackathons.
One facet of Hacker conferences that tends to differentiate many "HackerCons" from general computer security conferences, is the evolution of the conference badge. While many conferences use a fairly standard paper/plastic badge to identify attendees by name, many hacker con's have evolved to use more non-traditional badges, such as electronic PCB's with LED's, LCD screens, and can include wifi and advanced, often hidden functionality, to include games, that do not identify the individual, sometimes promoting a group identity or regional/local group affiliation. This has spurred the creation of so-called "badgelife" where different individuals and organizations (such as local hacker groups) may design, create, and sell or otherwise distribute a separate badge attendees wear in addition to their conference badge. These badges may be purchased, but some may have to be earned by completing a challenge at the conference. One of the rarest and most desirable badges is the DefCon Black Badge. While the use of the badges are traditionally associated with DefCon, their use has spread to other conferences.
Pixelflut is a common activity at hacker events. It is a protocol for software to draw a canvas. Usually this is done in a client-server architecture with multiple clients who send individual pixels and the server displays. The clients then overwrite each other's images on the same server. There are various variants of the protocol and different implementations for both the server and the client.
