Firefly

The Lampyridae are a family of insects in the beetle order Coleoptera. They are winged beetles, and commonly called fireflies or lightning bugs for their conspicuous use of bioluminescence during twilight to attract mates or prey. Fireflies produce a "cold light", with no infrared or ultraviolet frequencies. This chemically produced light from the lower abdomen may be yellow, green, or pale red, with wavelengths from 510 to 670 nanometers.

About 2,000 species of fireflies are found in temperate and tropical environments. Many are in marshes or in wet, wooded areas where their larvae have abundant sources of food. Their larvae emit light and often are called "glowworms", in particular, in Eurasia. In the Americas, "glow worm" also refers to the related Phengodidae. In many species, both male and female fireflies have the ability to fly, but in some species, the females are flightless.

Biology

Fireflies tend to be brown and soft-bodied, often with the elytra, or front wings, more leathery than those of other beetles. Although the females of some species are similar in appearance to males, larviform females are found in many other firefly species. These females can often be distinguished from the larvae only because they have compound eyes. The most commonly known fireflies are nocturnal, although there are numerous species that are diurnal. Most diurnal species are not luminescent; however, some species that remain in shadowy areas may produce light.

Firefly (InMe song)

"Firefly" is the second single by Essex alternative metal band InMe. The 2002 song starts off very melodic with guitar harmonics and a drum and bass driven verse. It then progresses to a heavier pre-chorus/chorus. The chorus and breakdown have the repetitive lyric "It's all over now / You've killed me".

About

From the syncopated strike on the snare to the electrifying sound of the lead guitar and the bass, all bands make their mark by offering a different kind of entertainment to audiences. The Firefly band differentiates itself from the competition by singing not only about love or heartbreak but by articulating ways on how to prevent destructive fires.

The name of the band, which means Firemen Forever Love You, first jammed together during the Bureau of Fire Protection (BFP) Christmas Party on December 22, 2002. Since then, the group continued to deliver their unique message through original songs, most of which are compiled in an album titled Langit. This 10-track album has the carrier single "Langit", which features Cesar Apolinario as the singer. It also includes the tracks "Kasama Mo Ako" featuring Rico J. Puno, "Trapik", "Kalikasan", "Sunog", "Taong Grasa", "Mr. Bell", "Hoy!", "I Love You", and "Nasaan Ka Na".

Shutdown (economics)

In economics, a firm will choose to implement a shutdown of production when the revenue received from the sale of the goods or services produced cannot even cover the fixed costs of production. In that situation, the firm will experience a higher loss when it produces, compared to not producing at all.

Technically, shutdown occurs if marginal revenue is below average variable cost at the profit-maximizing positive level of output. Producing anything would not generate revenue significant enough to offset the associated variable costs; producing some output would add losses (additional costs in excess of revenues) to the costs inevitably being incurred (the fixed costs). By not producing, the firm loses only the fixed costs.

Explanation

The goal of a firm is to maximize profits or minimize losses. The firm can achieve this goal by following two rules. First, the firm should operate, if at all, at the level of output where marginal revenue equals marginal cost. Second, the firm should shut down rather than operate if it can reduce losses by doing so.

Music video

Here the band are performing in a power station with CGI used in the final edit. Then during the bridge part of the song the band freeze for a moment and we see a man climbing a rope (possibly this man is J.S. Clayden). Then he falls off during the final moments of the song. And finally destroying their instruments in the end.

Shutdown (computing)

To shut down or power off a computer is to remove power from a computer's main components in a controlled way. After a computer is shut down, main components such as CPUs, RAM modules and hard disk drives are powered down, although some internal components, such as an internal clock, may retain power.

Implementations

Windows

In Microsoft Windows, a PC or server is shut down by selecting the Shutdown item from the Start menu on the desktop. Options include shutting down the system and powering off, automatically restarting the system after shutting down, or putting the system into stand-by mode. There is also a shutdown command that can be executed within a command shell window. shutdown.exe is the command-line shutdown application that can shut down the user's computer or another computer on the user's network.

Just like other operating systems, Windows has the option to prohibit selected users from shutting down a computer. On a home PC, every user may have the shutdown option, but in computers on large networks (such as Active Directory), an administrator can revoke the access rights of selected users to shut down a Windows computer. Nowadays there are many software utilities which can automate the task of shutting down a Windows computer, enabling automatic computer control. The Windows Shutdown website lists various software utilities to automate the task of shutting down.
