Heartbeat (company)

Heartbeat (sometimes Heart Beat) was a Japanese video game developer, famous for developing the sixth and seventh installments of the Dragon Quest series. Heartbeat also developed a remake of Dragon Quest IV. Plans to localize this remake in North America were halted when the employees of Heartbeat decided to take a sabbatical. The company stated its reason was "the raise of development costs", despite the massive financial success of its games. The company no longer exists but several of its members have created Genius Sonority, a company that develops games for Nintendo.

Heartbeat (2PM song)

"Heartbeat" is a song by K-pop band 2PM. It was released on November 10, 2009, as the lead single for The First Album 01:59PM. The song peaked at No. 1 on the Gaon Chart.

Promotion

Six teaser videos, each featuring one of the band members, were released in the weeks leading up to the album's release on YouTube. The videos started with various close-up shots of the band members hooked up to medical equipment and speaking. The videos then pan to a heartbeat monitor, play a short clip of the song, and displays the text "What is your Heartbeating for?" Taecyeon's video mentioned the inclusion of seven members in the band, although the seventh member (Jaebeom) exited the group before release of "Heartbeat."

Release and chart performance

The song peaked at #1 on the Gaon Chart.

Music video

The song's music video was released on November 11, 2009, the day after the song's release. It features dark, moody visuals. The color palette is mostly blacks, greys, and whites. It is the band's first music video to exclude Jaebeom, who left the band a few months before the video's release.

Heartbeat (computing)

In computer science, a heartbeat is a periodic signal generated by hardware or software to indicate normal operation or to synchronize other parts of a system. Usually a heartbeat is sent between machines at a regular interval on the order of seconds. If a heartbeat isn't received for a time—usually a few heartbeat intervals—the machine that should have sent the heartbeat is assumed to have failed.

Heartbeat protocol

A heartbeat protocol is generally used to negotiate and monitor the availability of a resource, such as a floating IP address. Typically when a heartbeat starts on a machine, it will perform an election process with other machines on the heartbeat network to determine which machine, if any, owns the resource. On heartbeat networks of more than two machines, it is important to take into account partitioning, where two halves of the network could be functioning but not able to communicate with each other. In a situation such as this, it is important that the resource is only owned by one machine, not one machine in each partition.

Lucid (programming language)

Lucid is a dataflow programming language. It is designed to experiment with non-von Neumann programming models. It was designed by Bill Wadge and Ed Ashcroft and described in the book Lucid, the Dataflow Programming Language.

Model

Lucid uses a demand-driven model for data computation. Each statement can be understood as an equation defining a network of processors and communication lines between them through which data flows. Each variable is an infinite stream of values and every function is a filter or a transformer. Iteration is simulated by 'current' values and 'fby' (read as 'followed by') operator allowing composition of streams.

Lucid is based on an algebra of histories, a history being an infinite sequence of data items. Operationally, a history can be thought of as a record of the changing values of a variable, history operations such as first and next can be understood in ways suggested by their names. Lucid was originally conceived as a kind of very disciplined, mathematically pure, single-assignment language, in which verification would be very much simplified. However, the dataflow interpretation has been a very important influence on the direction in which Lucid has evolved.

Lucid (album)

Lucid is the fifth studio album by American R&B singer Lyfe Jennings. The album was released on October 8, 2013, by Mass Appeal Entertainment. On May 8, 2013, the album's first single "Boomerang" was released. On July 25, 2013, the music video was released for "Boomerang".

Critical response

Lucid was met with a generally positive reviews from music critics. Andy Kellman of AllMusic gave the album three out of four stars, saying "Jennings draws character sketches, spins cautionary tales—as someone still growing, learning from his mistakes—and largely sticks to the type of mature R&B that his listeners don't get from anyone else. He briefly breaks from the norm with "Rock," a classy but contemporary steppers groove that's one of his best songs. Despite a mostly new cast of collaborators—including TGT associate Brandon Hodge and producer/songwriter Lashaunda "Babygirl" Carr—Lucid is a natural progression for a veteran artist who seems to have plenty left to express."
