EROS (microkernel)

EROS (The Extremely Reliable Operating System) is an operating system developed beginning in 1991 by The EROS Group, LLC., the Johns Hopkins University, and the University of Pennsylvania. Features include automatic data and process persistence, some preliminary real-time support, and capability-based security. EROS is purely a research operating system, and was never deployed in real world use. As of 2005, development has stopped in favor of two successor systems, CapROS and Coyotos.

Key concepts

The overriding goal of the EROS system (and its relatives) is to provide strong support at the operating system level for the efficient restructuring of critical applications into small communicating components. Each component can communicate with the others only through protected interfaces, and is isolated from the rest of the system. A "protected interface", in this context, is one that is enforced by the lowest level part of the operating system (the kernel). The kernel is the only portion of the system that can move information from one process to another. It also has complete control of the machine and (if properly constructed) cannot be bypassed. In EROS, the kernel-provided mechanism by which one component names and invokes the services of another is capabilities using inter-process communication (IPC). By enforcing capability-protected interfaces, the kernel ensures that all communications to a process arrive via an intentionally exported interface. It also ensures that no invocation is possible unless the invoking component holds a valid capability to the invokee. Protection in capability systems is achieved by restricting the propagation of capabilities from one component to another, often through a security policy known as confinement.

Shaftesbury Memorial Fountain

The Shaftesbury Memorial Fountain is located at the southeastern side of Piccadilly Circus in London, United Kingdom. Moved after World War II from its original position in the centre, it was erected in 1892–1893 to commemorate the philanthropic works of Lord Shaftesbury, who was a famous Victorian politician and philanthropist.

The monument is surmounted by Alfred Gilbert's winged nude statue generally known as Eros. This has been called "London's most famous work of sculpture"; a graphical illustration of it is used as the symbol of the Evening Standard newspaper and appears on its masthead. It was the first sculpture in the world to be cast in aluminium and is set on a bronze fountain, which itself inspired the marine motifs that Gilbert carved on the statue.

The use of a nude figure on a public monument was controversial at the time of its construction, but it was generally well received by the public. The Magazine of Art described it as "...a striking contrast to the dull ugliness of the generality of our street sculpture, ... a work which, while beautifying one of our hitherto desolate open spaces, should do much towards the elevation of public taste in the direction of decorative sculpture, and serve freedom for the metropolis from any further additions of the old order of monumental monstrosities."

Eros (film)

Eros is a 2004 anthology film consisting of three short segments: The Hand directed by Wong Kar-wai in Mandarin, Equilibrium by Steven Soderbergh in English, and The Dangerous Thread of Things by Michelangelo Antonioni in Italian. Each of the three segments addresses the themes of love and sex.

Plot

Miss Hua, a beautiful, 1960s high-end call girl is visited by a shy dressmaker's assistant Zhang, to take her measure. He hears the sounds of sex, as he waits in her living room. He is drawn towards her but there is no meeting ground between the two individuals from completely different classes. She summons him when her client leaves. She tells him, she will supply him with an aid to his memory. He will think about her while designing her clothes, she says.

Nick Penrose is an advertising executive under enormous pressure at work. He tells his psychiatrist Dr Pearl about a recurring dream of a beautiful naked woman in his apartment, as they discuss the possible reasons why his stress seems to manifest itself in the erotic dream.

Holocene

The Holocene /ˈhɒləˌsiːn, ˈhoʊ-/ is the geological epoch that began after the Pleistocene at approximately 11,700 years before the year 2000AD and continues to the present. The term "Recent" (usually capitalised) has often been used as an exact synonym of "Holocene", although this usage is discouraged in 21st-century work. The Holocene is part of the Quaternary period. Its name comes from the Greek words ὅλος (holos, whole or entire) and καινός (kainos, new), meaning "entirely recent". It has been identified with the current warm period, known as MIS 1, and can be considered an interglacial in the current ice age based on that evidence.

The Holocene also encompasses the growth and impacts of the human species worldwide, including all its written history, development of major civilizations, and overall significant transition toward urban living in the present. Human impacts on modern-era Earth and its ecosystems may be considered of global significance for future evolution of living species, including approximately synchronous lithospheric evidence, or more recently atmospheric evidence of human impacts. Given these, a new term, Anthropocene, is specifically proposed and used informally only for the very latest part of modern history and of significant human impact since the epoch of the Neolithic Revolution (around 12,000 years BP).

Holocene (song)

"Holocene" is a song by American indie folk band Bon Iver. It was released as the second single from their eponymous album Bon Iver, Bon Iver on 5 September 2011. The single is backed with a cover of Peter Gabriel's song "Come Talk to Me" as a B-side, which was previously released as a limited edition song for Record Store Day. The song was named one of the best songs of 2011 by various music publications. It was nominated for Song of the Year and Record of the Year for the 54th Grammy Awards, and is featured in the Cameron Crowe film We Bought a Zoo,Zach Braff's film Wish I Was Here, and the 2014 film The Judge.

Background

Front man Justin Vernon explained the song title in an interview with Mojo: "It's partly named after the (geological) era, but it's also the name of a bar in Portland where I had a dark night of the soul." He also stated that "the title is a metaphor for when you're not doing well. But it's also a song about redemption and realizing that you're worth something; that you're special and not special at the same time."
