Operation Legacy was a British Colonial Office (later Foreign Office) programme to destroy or hide files, to prevent them being inherited by its ex-colonies. It ran from the 1950s until the 1970s, when the decolonisation of the British Empire was at its height.

MI5 or Special Branch agents vetted all secret documents in the colonial administrations to find those that those that could embarrass the British government—for instance by showing racial or religious bias. They identified 8,800 files to conceal from at least 23 countries and territories in the 1950s and 1960s, and destroyed them or sent them to the United Kingdom. Precise instructions were given for methods to be used for destruction, including burning and dumping at sea. Some of the files detailed torture methods used against opponents of the colonial administrations, such as during the Mau Mau Uprising.

As decolonisation progressed, British officials were keen to avoid a repeat of the embarrassment that had been caused by the overt burning of documents that took place in New Delhi in 1947, which had been covered by Indian news sources. On 3 May 1961, Iain Macleod, who was Secretary of State for the Colonies, wrote a telegram to all British embassies to advise them on the best way to retrieve and dispose of sensitive documents. To prevent post-colonial governments from ever learning about Operation Legacy, officials were required to dispatch "destruction certificates" to London. In some cases, as the handover date approached, the immolation task proved so huge that colonial administrators warned the Foreign Office that there was a danger of "celebrating Independence Day with smoke."

Academic study of the end of the British Empire has been assisted in recent years by the declassification of the migrated archives in the Foreign and Commonwealth Office (FCO) 141 series. After the UK government admitted in 2011 that it had secret documents related to the Mau Mau Uprising, it began to declassify documents and by November 2013 some 20,000 files had been declassified. These documents can now be accessed at the National Archives in Kew, London.

The McMurdo Dry Valleys are a row of largely snow-free valleys in Antarctica, located within Victoria Land west of McMurdo Sound. The Dry Valleys experience extremely low humidity and surrounding mountains prevent the flow of ice from nearby glaciers. The rocks here are granites and gneisses, and glacial tills dot this bedrock landscape, with loose gravel covering the ground. It is one of the driest places on Earth and has not seen rain for nearly 2 million years.

The region is one of the world's most extreme deserts, and includes many features including Lake Vida, a saline lake, and the Onyx River, a meltwater stream and Antarctica's longest river. Although no living organisms have been found in the permafrost here, endolithic photosynthetic bacteria have been found living in the relatively moist interior of rocks, and anaerobic bacteria, with a metabolism based on iron and sulfur, live under the Taylor Glacier.

🔗 Philosophy 🔗 Philosophy/Logic

Trivialism (from Latin trivialis 'found everywhere') is the logical theory that all statements (also known as propositions) are true and that all contradictions of the form "p and not p" (e.g. the ball is red and not red) are true. In accordance with this, a trivialist is a person who believes everything is true.

In classical logic, trivialism is in direct violation of Aristotle's law of noncontradiction. In philosophy, trivialism is considered by some to be the complete opposite of skepticism. Paraconsistent logics may use "the law of non-triviality" to abstain from trivialism in logical practices that involve true contradictions.

Theoretical arguments and anecdotes have been offered for trivialism to contrast it with theories such as modal realism, dialetheism and paraconsistent logics.

🔗 Computing

The ST3000DM001 is a hard disk drive released by Seagate Technology in 2011 as part of the Seagate Barracuda series. It has a capacity of 3 terabytes (TB) and a spindle speed of 7200 RPM. This particular drive model was reported to have unusually high failure rates, approximately 5.7 times higher fail rates in comparison to other 3 TB drives.

In cryptography and computer science, a hash tree or Merkle tree is a tree in which every leaf node is labelled with the cryptographic hash of a data block, and every non-leaf node is labelled with the cryptographic hash of the labels of its child nodes. Hash trees allow efficient and secure verification of the contents of large data structures. Hash trees are a generalization of hash lists and hash chains.

Demonstrating that a leaf node is a part of a given binary hash tree requires computing a number of hashes proportional to the logarithm of the number of leaf nodes of the tree; this contrasts with hash lists, where the number is proportional to the number of leaf nodes itself.

The concept of hash trees is named after Ralph Merkle, who patented it in 1979.

🔗 Politics

In political jargon, a self-licking ice cream cone is a self-perpetuating system that has no purpose other than to sustain itself. The phrase appeared to have been first used in 1992, in On Self-Licking Ice Cream Cones, a paper by Pete Worden about NASA's bureaucracy. James A. Vedda described it as "Why do humans go into space? So we can go farther into space!"

Since then, the term has been used to describe the habit of government funded organisations and programs spending taxpayer money to lobby for more funding from the taxpayer. Other things compared have included financial bubbles, chatshows and reality television. In The Irish Times, Kevin Courtney observed that "many organisations are also stuck in limbo, destined to keep lurching on without ever achieving their stated goal. That’s because their real goal is simply to carry on regardless." The Cold War infrastructure has also been compared to a self-licking ice cream cone, given that expensive projects continued to be financed long after world communism had ceased to pose a viable threat.

Richard Hoggart used the term to describe certain United Nations programmes.

In sport, the Bowl Alliance was criticised using the term.

The tall poppy syndrome is the cultural phenomenon of jealous people holding back or directly attacking those who are perceived to be better than the norm, "cutting down the tall poppy". It describes a draw towards mediocrity.

Commonly in Australia and New Zealand, "Cutting down the tall poppy" is used to describe those who think too highly of themselves and it is seen by some as self-deprecating and by others as promoting modesty and egalitarianism.

Abram Petrovich Gannibal, also Hannibal or Ganibal, or Abram Hannibal or Abram Petrov (Russian: Абра́м Петро́вич Ганниба́л; c. 1696 – 14 May 1781), was a Russian military engineer, major-general, and nobleman of African origin. Kidnapped as a child, Gannibal was taken to Russia and presented as a gift to Peter the Great, where he was freed, adopted and raised in the Emperor's court household as his godson.

Gannibal eventually rose to become a prominent member of the imperial court in the reign of Peter's daughter Elizabeth. He had 11 children, most of whom became members of the Russian nobility; he was a great-grandfather of the author and poet Alexander Pushkin.

🔗 Poetry

"Dane-geld" is a poem by British writer Rudyard Kipling (1865-1936). It relates to the unwisdom of paying "Danegeld", or what is nowadays called blackmail and protection money. The most famous lines are "once you have paid him the Danegeld/ You never get rid of the Dane."

The Corpus Clock, also known as the Grasshopper clock, is a large sculptural clock at street level on the outside of the Taylor Library at Corpus Christi College, Cambridge University, in the United Kingdom, at the junction of Bene't Street and Trumpington Street, looking out over King's Parade. It was conceived and funded by John C. Taylor, an old member of the college.

It was officially unveiled to the public on 19 September 2008 by Cambridge physicist Stephen Hawking. The clock was named one of Time's Best Inventions of 2008.
