Balloon busters were military pilots known for destroying enemy observation balloons. These pilots were noted for their fearlessness, as balloons were stationary targets able to receive heavy defenses, from the ground and the air. Seventy-seven flying aces in World War I were each credited with destroying five or more balloons, and thus were balloon aces.

The Sayfo or the Seyfo (lit. 'sword'; see below), also known as the Assyrian genocide, was the mass slaughter and deportation of Assyrian/Syriac Christians in southeastern Anatolia and Persia's Azerbaijan province by Ottoman forces and some Kurdish tribes during World War I.

The Assyrians were divided into mutually antagonistic churches, including the Syriac Orthodox Church, the Church of the East, and the Chaldean Catholic Church. Before World War I, they lived in mountainous and remote areas of the Ottoman Empire (some of which were effectively stateless). The empire's nineteenth-century centralization efforts led to increased violence and danger for the Assyrians.

Mass killing of Assyrian civilians began during the Ottoman occupation of Azerbaijan from January to May 1915, during which massacres were committed by Ottoman forces and pro-Ottoman Kurds. In Bitlis province, Ottoman troops returning from Persia joined local Kurdish tribes to massacre the local Christian population (including Assyrians). Ottoman forces and Kurds attacked the Assyrian tribes of Hakkari in mid-1915, driving them out by September despite the tribes mounting a coordinated military defense. Governor Mehmed Reshid initiated a genocide of all of the Christian communities in Diyarbekir province, including Syriac Christians, facing only sporadic armed resistance in some parts of Tur Abdin. Ottoman Assyrians living farther south, in present-day Iraq and Syria, were not targeted in the genocide.

The Sayfo occurred concurrently with and was closely related to the Armenian genocide, although the Sayfo is considered to have been less systematic. Local actors played a larger role than the Ottoman government, but the latter also ordered attacks on certain Assyrians. Motives for killing included a perceived lack of loyalty among some Assyrian communities to the Ottoman Empire and the desire to appropriate their land. At the 1919 Paris Peace Conference, the Assyro-Chaldean delegation said that its losses were 250,000 (about half the prewar population); the accuracy of this figure is unknown. They later revised their estimate to 275,000 dead at the Lausanne Conference in 1923. The Sayfo is less studied than the Armenian genocide. Efforts to have it recognized as a genocide began during the 1990s, spearheaded by the Assyrian diaspora. Although several countries acknowledge that Assyrians in the Ottoman Empire were victims of a genocide, this assertion is rejected by the Turkish government.

🔗 Internet culture

Warnock's dilemma, named for its originator Bryan Warnock, is the problem of interpreting a lack of response to a posting in a virtual community. The term originally referred to mailing list discussions, but has been applied to Usenet posts, blogs, web forums, and online content in general. The dilemma arises because a lack of response does not necessarily imply that no one is interested in the topic, but could also mean for example that readers find the content to be exceptionally good (leaving nothing for commenters to add).

On many Internet forums, only around one percent of users create new posts, while nine percent reply and 90 percent are lurkers that do not contribute to the discussion. When no users reply, the original poster has no way of knowing what lurkers think of their contribution.

Warnock's dilemma leads to online writers and publishers adopting more provocative writing strategies in order to ensure that they will get a response. However, this can also lead publishers to avoid producing the kind of content that might fail to generate comments due to its high quality. This problem arises particularly with sites that focus on viral content, such as BuzzFeed and Huffington Post.

The Zone Rouge (English: Red Zone) is a chain of non-contiguous areas throughout northeastern France that the French government isolated after the First World War. The land, which originally covered more than 1,200 square kilometres (460 sq mi), was deemed too physically and environmentally damaged by conflict for human habitation. Rather than attempt to immediately clean up the former battlefields, the land was allowed to return to nature. Restrictions within the Zone Rouge still exist today, although the control areas have been greatly reduced.

The Zone Rouge was defined just after the war as "Completely devastated. Damage to properties: 100%. Damage to Agriculture: 100%. Impossible to clean. Human life impossible".

Under French law, activities such as housing, farming, or forestry were temporarily or permanently forbidden in the Zone Rouge, because of the vast amounts of human and animal remains, and millions of items of unexploded ordnance contaminating the land. Some towns and villages were never permitted to be rebuilt after the war.

"The Analytical Language of John Wilkins" (Spanish: "El idioma analítico de John Wilkins") is a short essay by Argentine writer Jorge Luis Borges, first printed in La Nación on 8 February 1942 and subsequently published in Otras Inquisiciones (1937–1952). It is a critique of the English natural philosopher and writer John Wilkins's proposal for a universal language and of the representational capacity of language generally. In it, Borges imagines a bizarre and whimsical (and fictional) Chinese taxonomy later quoted by Michel Foucault, David Byrne, and others.
