Unstable (song)

"Unstable" is the first single released from the Adema album, Unstable. It is featured in Madden NFL 2004

Unstable (album)

Unstable is Adema's second and also final album to feature its original lineup with vocalist Mark Chavez departing from the band after its release and then again after their reunion. It was released on August 12, 2003. It has sold about 400,000 copies worldwide. Its radio single was the self-titled song "Unstable", which also had a music video, but it didn't get very much radio play. Many songs relied more on instrumentation and harmony instead of distortion in comparison to their previous album, but the album also has some of the band's most aggressive work. It was less successful than their first album, debuting at number 43 on the Billboard 200 before quickly falling off the chart.

Unstable (Debian)

In the Debian jargon, unstable is the development distribution of Debian. It is codenamed sid (after the boy next door who broke toys in Toy Story). As unstable never becomes testing, this codename is permanent, contrary to the codenames of stable and testing, which have volatile codenames.

unstable has some newer packages, but suffers from an unusually high number of serious bugs, as many packages are new. In development periods, the number of bugs considered "Release-Critical" by the Debian project in unstable is typically between 2 and 3 times as many as the number in testing.

unstable is targeted at Debian developers for building packages to be uploaded to unstable, and other Debian users that know Debian well in general, master Debian package management, are good for reporting bugs, want to help the Debian project, and have some machines on which they don't depend.
