Proxmox Virtual Environment (Proxmox VE or PVE) is an open-source software server for virtualization management. It is a hosted hypervisor that can run operating systems including Linux and Windows on x64 hardware. It is a Debian-based Linux distribution with a modified Ubuntu LTS kernel and allows deployment and management of virtual machines and containers. Proxmox VE includes a web console and command-line tools, and provides a REST API for third-party tools. Two types of virtualization are supported: container-based with LXC (starting from version 4.0 replacing OpenVZ used in version up to 3.4, included), and full virtualization with KVM. It includes a web-based management interface.

Proxmox VE is licensed under the GNU Affero General Public License, version 3.

The free will theorem of John H. Conway and Simon B. Kochen states that if we have a free will in the sense that our choices are not a function of the past, then, subject to certain assumptions, so must some elementary particles. Conway and Kochen's paper was published in Foundations of Physics in 2006. In 2009 they published a stronger version of the theorem in the Notices of the AMS. Later, in 2017, Kochen elaborated some details.

Coherent is a clone of the Unix operating system for IBM PC compatibles and other microcomputers, developed and sold by the now-defunct Mark Williams Company (MWC). Historically, the operating system was a proprietary product, but it became open source in 2015, released under a 3-clause BSD License.

The Gopher protocol is a communications protocol designed for distributing, searching, and retrieving documents in Internet Protocol networks. The design of the Gopher protocol and user interface is menu-driven, and presented an alternative to the World Wide Web in its early stages, but ultimately fell into disfavor, yielding to the Hypertext Transfer Protocol (HTTP). The Gopher ecosystem is often regarded as the effective predecessor of the World Wide Web.

The protocol was invented by a team led by Mark P. McCahill at the University of Minnesota. It offers some features not natively supported by the Web and imposes a much stronger hierarchy on the documents it stores. Its text menu interface is well-suited to computing environments that rely heavily on remote text-oriented computer terminals, which were still common at the time of its creation in 1991, and the simplicity of its protocol facilitated a wide variety of client implementations. More recent Gopher revisions and graphical clients added support for multimedia. Gopher was preferred by many network administrators for using fewer network resources than Web services.

Gopher's hierarchical structure provided a platform for the first large-scale electronic library connections. The Gopher protocol is still in use by enthusiasts, and although it has been almost entirely supplanted by the Web, a small population of actively-maintained servers remains.

In psychology, the four stages of competence, or the "conscious competence" learning model, relates to the psychological states involved in the process of progressing from incompetence to competence in a skill. People may have several skills, some unrelated to each other, and each skill will typically be at one of the stages at a given time. Many skills require practice to remain at a high level of competence.

The four stages suggest that individuals are initially unaware of how little they know, or unconscious of their incompetence. As they recognize their incompetence, they consciously acquire a skill, then consciously use it. Eventually, the skill can be utilized without it being consciously thought through: the individual is said to have then acquired unconscious competence.

Fluidics, or fluidic logic, is the use of a fluid to perform analog or digital operations similar to those performed with electronics.

The physical basis of fluidics is pneumatics and hydraulics, based on the theoretical foundation of fluid dynamics. The term fluidics is normally used when devices have no moving parts, so ordinary hydraulic components such as hydraulic cylinders and spool valves are not considered or referred to as fluidic devices.

A jet of fluid can be deflected by a weaker jet striking it at the side. This provides nonlinear amplification, similar to the transistor used in electronic digital logic. It is used mostly in environments where electronic digital logic would be unreliable, as in systems exposed to high levels of electromagnetic interference or ionizing radiation.

Nanotechnology considers fluidics as one of its instruments. In this domain, effects such as fluid-solid and fluid-fluid interface forces are often highly significant. Fluidics have also been used for military applications.

International Men's Day (IMD) is a global awareness day for many issues that men face, including parental alienation, abuse, homelessness, suicide, and violence, celebrated annually on November 19. The objectives of celebrating an International Men's Day are set out in 'All the Six Pillars of International Men's Day'. It is also an occasion to celebrate boys' and men's lives, achievements and contributions, in particular for their contributions to nation, union, society, community, family, marriage, and childcare.

The Rational Dress Society was an organisation founded in 1881 in London, part of the movement for Victorian dress reform. It described its purpose thus:

The Rational Dress Society protests against the introduction of any fashion in dress that either deforms the figure, impedes the movements of the body, or in any way tends to injure the health. It protests against the wearing of tightly-fitting corsets; of high-heeled shoes; of heavily-weighted skirts, as rendering healthy exercise almost impossible; and of all tie down cloaks or other garments impeding on the movements of the arms. It protests against crinolines or crinolettes of any kind as ugly and deforming... [It] requires all to be dressed healthily, comfortably, and beautifully, to seek what conduces to birth, comfort and beauty in our dress as a duty to ourselves and each other.

In the catalogue of its inaugural exhibition, it listed the attributes of "perfect" dress as:

1. Freedom of Movement.
2. Absence of pressure over any part of the body.
3. Not more weight than is necessary for warmth, and both weight and warmth evenly distributed.
4. Grace and beauty combined with comfort and convenience.
5. Not departing too conspicuously from the ordinary dress of the time.

Leading members of the Society were Lady Harberton (who created the divided skirt), Mary Eliza Haweis and Constance Wilde (Irish author). Oscar Wilde helped spread the word by publishing the essay "The Philosophy of Dress" in which he stressed the important relationship between clothing and one’s soul. Woman cyclists, such as members of the Lady Cyclists' Association, were keen advocates of women's right to dress appropriately for the activity, as part of a belief that cycling offered women an opportunity to escape overly restrictive societal norms.

In 1889, a member of the Rational Dress Society, Charlotte Carmichael Stopes, staged a coup at a meeting of the British Association for the Advancement of Science in Newcastle upon Tyne, when she arranged an impromptu addition to the programme on the subject of rational dress. Her speech was reported by newspapers across Britain and the notion of rational dress was the biggest news from the meeting.

The naming law in Sweden (Swedish: lag om personnamn) is a Swedish law which requires approval of the government agency for names to be given to Swedish children. The parents must submit the proposed name of a child within three months of birth. The current law was enacted in 2017, replacing a 1982 law. The Swedish Tax Agency administers the registration of names in Sweden. The law has been revised since originally enacted; in 1983, it was made possible for men to adopt their wife's or partner's name, as well as for women to adopt their husband's name.

The 1982 law states, in part: "First names shall not be approved if they can cause offense or can be supposed to cause discomfort for the one using it, or names which for some obvious reason are not suitable as a first name" (§ 34). This text applies both when parents name their children and when an adult wants to change their own name. When changing a name, the first change is free of charge as long as at least one of the names given at birth is kept, and such a change is only allowed once per person. Further name changes require fee payment. The law states nothing about registering which name is used on a daily basis, but the tax authority can register that if requested.
