/g/ is 4chan's technology discussion board. The board letter /g/ stands for gijutsu (技術), the Japanese word for technology.
/g/ - Technology was created in mid-January of 2005, amidst a major restructuring in an attempt to make 4chan more appealing to advertisers and normalfags, and less of a breeding ground for pedophiles. Like everything moot does, the restructure changed nothing, and only served to made 4chan's heavily prominent undertones of pedophilia and sexual frustration much more prevalent.
/g/ - Guro
Prior to October of 2004, /g/ was 4chan's guro board, home to all manner of violent, grotesque and gory anime art.
/g/ - Guro was deleted in October of 2004 along with /l/ - Lolikon, but their spirit continues to live on at /g/ - Technology, which is frequently the host of many blatantly off-topic and unabashed loli/guro dump threads with almost zero moderator intervention.
Tox is a WIP secure instant messaging client. It's meant to be a Skype replacement, created directly in response to the Snowden NSA leaks.
MooGNU is a copyleft alternative to the popular NyanCat animation. It was created by /g/ in response to the pre-emptive removal of NyanCat from the Desktop Environment MATE due to concerns by the developers about NyanCat's copyright status.
LiveChan is an IRC-like 4chan clone with dynamic post updates and loads of other features. Programmed in node.js by emgram, LiveChan is still in development. Open-source, but non-free software.
