For many avid gamers, the idea of a gaming marathon sounds like heaven. But just how long is too long when it comes to a continuous session? One gamer has pushed himself to the limit after playing nearly 60 continuous hours of'World of Warcraft' to break the world record. But his impressive feat didn't come without its risks. Barnabás Vujity-Zsolnay admits he got bored 30 hours into the session, while he even started to experience'mild hallucinations' from hour 45!

If you recognise any of these retro Apple computers, now may be a good time to have a rummage through your attic. That's because the set of over 500 devices is going up for auction on Thursday, and is expected to rake in thousands of dollars. 'The Hanspeter Luzi Vintage Apple Archive' is said to be one of the world's most comprehensive collection of Apple computers and products ever offered. It includes a rare 1983 Lisa I computer, which is currently estimated to sell for up to $3,000 (£2,400) alone. All devices were collected by the late Hanspeter Luzi, a Swiss special educational needs teacher who used computers as part of his lessons.

It is the largest collection of video games in the world, worth a whopping $2.1 million (£1.69 million) - but the owner insists he is not done and plans to build on his expensive hobby. Antonio Romero Monteiro, 45, from Texas, USA, has broken the Guinness World record for the largest collection of video games. The avid gamer, whose multi-million-dollar collection began in 1987 when he was just 10-years-old, has collected a whopping 24,268 video games. Mr Monteiro now holds the record for largest collection of Xbox items, largest collection of Sega items, largest collection of Nintendo items, largest collection of PlayStation items and largest collection of video games overall.

The world of an 80s teenager was one of arcade machines, LPs and Nintendo game consoles. And now you can step back in time and enter that world thanks to a computer museum that has recreated it using a series of fascinating exhibitions. They include an 80s classroom with'state-of-the-art' Apple IIe computers, a'friend's basement' that contains wood-panelled walls and a classic Nintendo Entertainment System (NES) console, and a videogame arcade. A typical basement from the 1980s has been recreated at the Living Computers: Museum Labs in Seattle. There is also a 1980s classroom packed with Apple IIe computers.

Image recognition AIs that have been trained by some of the most-used research-photo collections are developing sexist biases, according to a new study. University of Virginia computer science professor Vicente Ordóñez and colleagues tested two of the largest collections of photos and data used to train these types of AIs (including one supported by Facebook and Microsoft) and discovered that sexism was rampant. He began the research after noticing a disturbing pattern of sexism in the guesses made by the image recognition software he was building. 'It would see a picture of a kitchen and more often than not associate it with women, not men,' Ordóñez told Wired, adding it also linked women with images of shopping, washing, and even kitchen objects like forks. The AI was also associating men with stereotypically masculine activities like sports, hunting, and coaching, as well as objects sch as sporting equipment.

DCPS' memory scheme is a modified version of the Random Receptors method [5]. The symbol space is the set of all triples over a 25 letter alphabet. Units have fixed-size receptive fields organized as 6 x 6 x 6 subspaces. Patterns are manipulated to minimize the variance in pattern size across symbols.
