An erratum or corrigendum (plurals: errata, corrigenda) (comes from Latin: errata corrige) is a correction of a published text. As a general rule, publishers issue an erratum for a production error (i.e., an error introduced during the publishing process) and a corrigendum for an author's error.[1] An erratum is most commonly issued shortly after its original text is published.

Patches to security issues in a computer program are also sometimes called errata. Erratum, like corrigendum, can also be used as a term for an error itself.

Errata sheets

According to the Chicago Manual of Style, "Errata, lists of errors and their corrections, may take the form of loose, inserted sheets or bound-in pages. An errata sheet is definitely not a usual part of a book. It should never be supplied to correct simple typographical errors (which may be rectified in a later printing) or to insert additions to, or revisions of, the printed text (which should wait for the next edition of the book). It is a device to be used only in extreme cases where errors severe enough to cause misunderstanding are detected too late to correct in the normal way but before the finished book is distributed. Then the errors may be listed with their locations and their corrections on a sheet that is tipped in, either before or after the book is bound, or laid in loose, usually inside the front cover of the book. (Tipping and inserting must be done by hand, thus adding considerably to the cost of the book.)"[2]

CPU logic

Design errors and mistakes in a CPU's hardwired logic may also be documented and described as errata. One well-publicized example is Intel's "FDIV" erratum in early Pentium processors,[3] known as the Pentium FDIV bug. This gave incorrect answers to a floating-point division instruction (FDIV) for a small set of numbers, due to an incorrect lookup table inside the Pentium chip.

21088 Chelyabinsk

21088 Chelyabinsk, provisional designation 1992 BL2, is a stony asteroid and near-Earth object of the Amor group, approximately 4 kilometers in diameter. It was discovered on 30 January 1992, by Belgian astronomer Eric Elst at ESO's La Silla Observatory in northern Chile. The asteroid was named after the Russian city of Chelyabinsk and for its spectacular Chelyabinsk meteor event in 2013.

At the Center of the Storm

At the Center of the Storm: My Years at the CIA is a memoir co-written by former Director of the Central Intelligence Agency George Tenet with Bill Harlow, former CIA Director of Public Affairs. The book was released on April 30, 2007 and outlines Tenet's version of 9/11, the War on Terrorism, the 2001 War in Afghanistan, the run-up to the 2003 Iraq war, rough interrogation and other events.

Bulbophyllum erratum

Bulbophyllum erratum is a species of orchid in the genus Bulbophyllum.

Cooperation Sea

Cooperation Sea, also called Commonwealth Sea (erratum) or Sodruzhestvo Sea, is a proposed sea name for part of the Southern Ocean, between Enderby Land (the eastern limit of which is 59°34'E) and West Ice Shelf (85°E), off the coast of MacRobertson Land and Princess Elizabeth Land. It would stretch over an area of 258,000 km². It would be bordered by the Davis Sea on the east, and by another Russian proposal to the 2002 International Hydrographic Organization (IHO) draft, a Cosmonauts Sea to the west.

The Cooperation Sea was named in 1962 by the Soviet Antarctic Expedition in honor of international science cooperation in Antarctica. The name first appeared as a proposal to the IHO in the IHO 2002 draft. This draft was never approved by the IHO (or any other organization), and the 1953 IHO document (which does not contain the name) remains currently in force. Leading geographic authorities and atlases do not use the name, including the 2014 10th edition of the World Atlas from the United States' National Geographic Society and the 2014 12th edition of the British Times Atlas of the World. But Soviet and Russian-issued maps do.Davis Station is located on the coast near here.

Florida naked-tailed rat

The Florida naked-tailed rat (Solomys salamonis) is a poorly known and possible extinct species of rodent in the family Muridae. It was confined to the Nggela Islands (previously known as Florida Islands) in the Solomon Islands. The originally mentioned type locality Ugi Island is an erratum.


Goldmont is a microarchitecture for low-power Atom, Celeron and Pentium branded processors used in systems on a chip (SoCs) made by Intel. The Apollo Lake platform with 14 nm Goldmont core was unveiled at the Intel Developer Forum (IDF) in Shenzhen, China, April 2016. The Goldmont architecture borrows heavily from the Skylake Core processors, so it offers a more than 30 percent performance boost compared to the previous Braswell platform, and it can be used to implement power-efficient low-end devices including Cloudbooks, 2-in-1 netbooks, small PCs, IP cameras, and in-car entertainment systems.

Herman A. Johnson

Herman Archibald Johnson (1916–2004) served during World War II as a Major with the Tuskegee Airman in the U.S. Army flying for the 99th-332nd and 477th Group.

Huai-Dong Cao

Huai-Dong Cao (born 8 November 1959 in Jiangsu) is A. Everett Pitcher Professor of Mathematics at Lehigh University and professor at Tsinghua University.

Professor Cao received his B.A. from Tsinghua University in 1981 and his Ph.D. from Princeton University in 1986 under the supervision of Shing-Tung Yau, a Fields Medalist and National Medal of Science recipient. Professor Cao's specialty is geometric analysis and he is an expert in the subject of Kähler–Ricci flow.

Cao is a former Associate Director, Institute for Pure and Applied Mathematics (IPAM) at UCLA. He has held visiting Professorships at MIT, Harvard University, Isaac Newton Institute, Max-Planck Institute, IHES, ETH Zurich, and University of Pisa. Professor Cao has received the John Simon Guggenheim Memorial Foundation Fellow (2004) and Alfred P. Sloan Foundation Research Fellowship (1991–1993). He is Managing Editor of Journal of Differential Geometry.

Cao collaborated with Xi-Ping Zhu of Zhongshan University in verifying Grigori Perelman's proof of the Poincaré conjecture. The Cao–Zhu team is one of three teams formed for this purpose. The other teams were the Tian–Morgan team (Gang Tian of Princeton University and John Morgan of Columbia University) and the Kleiner–Lott team (Bruce Kleiner of Yale University and John Lott of the University of Michigan). Cao and Xi-Ping Zhu published a paper in the June 2006 issue of the Asian Journal of Mathematics with an exposition of the complete proof of the Poincaré and geometrization conjectures. They initially implied the proof was their own achievement based on the "Hamilton-Perelman theory", but later retracted the original version of their paper, and posted a revised version, in which they referred to their work as the more modest "exposition of Hamilton–Perelman's proof". They also published an erratum disclosing that they had forgotten to cite properly the previous work of Kleiner and Lott published in 2003. In the same issue, the AJM editorial board issued an apology for what it called "incautions" in the Cao–Zhu paper.

Jean-Baptiste Pérès

Jean-Baptiste Pérès (1752–1840) was a French physicist best known for his 1827 pamphlet Grand Erratum, a polemical satire, translated into many European languages, that attempted "in the interest of conservative theology, to reduce to an absurdity the purely negative tendencies of the rationalistic criticism of the Scriptures then in vogue" (as Frederick W. Loetscher described what he called "the celebrated pamphlet" in The Princeton Theological Review 1906) through humorously suggesting ways in which the history of Napoleon Bonaparte could be shown to be an expression of an ancient sun myth.

Pérès was professor of mathematics and physics at the University of Lyon, later a government attorney and finally librarian at Agen.

K2K experiment

The K2K experiment (KEK to Kamioka) was a neutrino experiment that ran from June 1999 to November 2004. It used muon neutrinos from a well-controlled and well-understood beam to verify the oscillations previously observed by Super-Kamiokande using atmospheric neutrinos. This was the first positive measurement of neutrino oscillations in which both the source and detector were fully under experimenters' control. Previous experiments relied on neutrinos from the Sun or from cosmic sources. The experiment found oscillation parameters which were consistent with those measured by Super-Kamiokande.

Manifold Destiny

"Manifold Destiny" is an article in The New Yorker written by Sylvia Nasar and David Gruber and published in the August 28, 2006 issue of the magazine. It claims to give a detailed account (including interviews with many mathematicians) of some of the circumstances surrounding the proof of the Poincaré conjecture, one of the most important accomplishments of 20th and 21st century mathematics, and traces the attempts by three teams of mathematicians to verify the proof given by Grigori Perelman.

Subtitled "A legendary problem and the battle over who solved it", the article concentrates on the human drama of the story, especially the discussion on who contributed how much to the proof of the Poincaré conjecture. Interwoven with the article is an interview with the reclusive mathematician Grigori Perelman, whom the authors tracked down to the St. Petersburg apartment he shares with his mother, as well as interviews with many mathematicians. The article describes Perelman's disillusionment with and withdrawal from the mathematical community and paints an unflattering portrait of the 1982 Fields Medalist, Shing-Tung Yau. Yau has disputed the accuracy of the article and threatened legal action against the New Yorker. The New Yorker stood by its story and no lawsuit was filed.

The article was selected for inclusion in the book The Best American Science Writing 2007. Sylvia Nasar is best known for her biography of John Forbes Nash, A Beautiful Mind. David Gruber is a PhD recipient and graduate of Columbia University Graduate School of Journalism, who also wrote (with Vincent Pieribone) Aglow in the Dark, published by Harvard University Press.

Matthew Dillon

Matthew Dillon (born 1966) is an American software engineer known for Amiga software, contributions to FreeBSD and for starting and leading the DragonFly BSD project since 2003.Dillon studied electronic engineering and computer science at the University of California, Berkeley, where he first became involved with BSD in 1985. He also became known for his Amiga programming, his C compiler DICE and his work on the Linux kernel. He founded and worked at Best Internet from 1994 until 1997, contributing to FreeBSD in that time. His "Diablo" internet news transit program was very popular with many ISPs.

In 1997, Dillon gained commit access to the FreeBSD code and heavily contributed to the virtual memory subsystem, amongst other contributions.

Concerned with problems he saw in the direction FreeBSD 5.x was headed in regards to concurrency, and coupled with the fact that Dillon's access to the FreeBSD source code repository was revoked due to a falling-out with other FreeBSD developers, he started the DragonFly BSD project in 2003, implementing the SMP model using light-weight kernel threads. The DragonFly project also led to the development of a new userspace kernel virtualisation technique in 2006, called Virtual Kernel, originally to ease the development and testing of subsequent kernel-level features; a new file system, called HAMMER, which he created using B-trees; HAMMER was declared production-ready with DragonFly 2.2 in 2009; and, subsequently, HAMMER2, declared stable in 2018 with DragonFly 5.2.

Most recently, Dillon has gotten a number of headlines around CPU errata. In 2007, this was after Theo de Raadt of OpenBSD raised the alarm around the seriousness of some of the errata for Intel Core 2 family of CPUs. Dillon has independently evaluated Intel's errata, and did an overview of Intel Core errata as well, suggesting that several of the erratums were so serious as to warrant avoiding any processor where the issues remain unfixed. Dillon has since been a fan of AMD processors, and, subsequently in 2012, he has discovered a brand-new deficiency in some AMD processors for which no existing erratum existed at the time. Matt continued his work around CPU issues as late as 2018, presenting solutions to tackle the latest security vulnerabilities like meltdown, some of which have been subsequently adoped by OpenBSD as well.Matt was a frequent guest on bsdtalk during the runtime of the show, and was interviewed several times for KernelTrap.

Pentium F00F bug

The Pentium F00F bug is a design flaw in the majority of Intel Pentium, Pentium MMX, and Pentium OverDrive processors (all in the P5 microarchitecture). Discovered in 1997, it can result in the processor ceasing to function until the computer is physically rebooted. The bug has been circumvented through operating system updates.

The name is shorthand for F0 0F C7 C8, the hexadecimal encoding of one offending instruction. More formally, the bug is called the invalid operand with locked CMPXCHG8B instruction bug.

Platform Controller Hub

The Platform Controller Hub (PCH) is a family of Intel chipsets, introduced circa 2008. It is the successor to the Intel Hub Architecture, which used a northbridge and southbridge instead, and first appeared in the Intel 5 Series.

The PCH controls certain data paths and support functions used in conjunction with Intel CPUs. These include clocking (the system clock), Flexible Display Interface (FDI) and Direct Media Interface (DMI), although FDI is only used when the chipset is required to support a processor with integrated graphics. As such, I/O functions are reassigned between this new central hub and the CPU compared to the previous architecture: some northbridge functions, the memory controller and PCI-e lanes, were integrated into the CPU while the PCH took over the remaining functions in addition to the traditional roles of the southbridge.


Silvermont is a microarchitecture for low-power Atom, Celeron and Pentium branded processors used in systems on a chip (SoCs) made by Intel. Silvermont forms the basis for a total of four SoC families:

Merrifield and Moorefield – consumer SoCs intended for smartphones

Bay Trail – consumer SoCs aimed at tablets, hybrid devices, netbooks, nettops, and embedded/automotive systems

Avoton – SoCs for micro-servers and storage devices

Rangeley – SoCs targeting network and communication infrastructure.Silvermont was announced to news media on May 6, 2013 at Intel's headquarters at Santa Clara, California. Intel had repeatedly said the first Bay Trail devices would be available during the Holiday 2013 timeframe, while leaked slides showed that the release window for Bay Trail-T as August 28 – September 13, 2013. Both Avoton and Rangeley were announced as being available in the second half of 2013. The first Merrifield devices were announced in 1H14.Airmont is the 14 nm die shrink of Silvermont, launched in early 2015 and first seen in the Atom x7-Z8700 as used in the Microsoft Surface 3. Airmont microarchitecture includes the following SoC families:

Braswell – consumer SoCs aimed at PCs

Cherry Trail – consumer SoCs aimed at tablets.Silvermont based cores have also been used, modified, in the Knight's Landing iteration of Intel's Xeon Phi HPC chips.

Symphlebia erratum

Symphlebia erratum is a moth in the subfamily Arctiinae. It was described by Schaus in 1933. It is found in Venezuela.

The Book of Heroic Failures

The Book of Heroic Failures, written by Stephen Pile in 1979, is a book written in celebration of human inadequacy in all its forms. Entries include William McGonagall, a notoriously bad poet, and Teruo Nakamura, a soldier of the Imperial Japanese Army who fought for Japan in World War II until 1974.

The original edition included an application to become a member of the Not Terribly Good Club of Great Britain; however, this was taken out in later editions because the club received over 20,000 applications and closed in 1979 on the grounds that, "Even as failures, we failed" (but not before Pile himself had been expelled from it for publishing a bestseller). The American version of the book was misprinted by the publishers, who left out half the introduction. As a consequence, later versions of the book came out with an erratum slip longer than the entire introduction. In his second book The Return of Heroic Failures, published in 1988, Stephen Pile reports that Taiwanese pirates were not aware of this and did not include the erratum slip. The second book was published in the USA under the title Cannibals in the Cafeteria.

The second book came out in Greece in 1992 although the first one had never been published there. In fact, this second book was named "Η ΤΕΧΝΗ ΤΗΣ ΑΠΟΤΥΧΙΑΣ No1" (The Art of Failure No. 1). A small erratum slip in the book itself explains that it was a mistake. In an interview with English Radio DJ Andrew Marshall, Pile said, "The Book is one of the least successful books ever issued in the USA, I don't think it has reached double figures there as yet and long may that remain the case."

In 1999 Penguin made the decision to re-publish the book as part of their "Penguin Readers" series to encourage reading from a young age.

A third volume, The Ultimate Book of Heroic Failures, was published by Faber and Faber in 2011, and a selection from the first two volumes (the author's last ever word on the subject of heroic failure) was published in 2012.

The Truth About Uri Geller

The Truth About Uri Geller, formerly known as The Magic of Uri Geller, is a 1982 book by magician and skeptic James Randi about alleged psychic Uri Geller. In the book, Randi challenges Geller's assertions that he performs paranormal feats. Randi explores Geller's background as a stage magician, and explains how Geller's spoon bending can be easily reproduced by any magician using sleight of hand.

In 1991 Geller filed a $15 million lawsuit against Randi and the Committee for the Scientific Investigation of Claims of the Paranormal (CSICOP) over slander concerning Randi's statements that Geller had "tricked even reputable scientists" with tricks that "are the kind that used to be on the back of cereal boxes when I was a kid". The court dismissed the case and Geller had to eventually settle the case at a cost of $120,000.In February 1992, Geller sued Randi, Prometheus and local book distributors in London, England for libel concerning The Magic of Uri Geller. The lawsuit centered on the sentence: "He began his career as a stage magician in Israel where he was once arrested for claiming his feats were performed with psychic power", since Geller had not been arrested but merely sued. The publisher issued an erratum that changed the phrase "he was once arrested" to "he was once sued". Randi commented in 1993 that "My position is that I made an unintended factual error in misinterpreting the words 'brought to court' and 'guilty' as 'arrested,' and that this was done without malice or reckless disregard for the truth." Geller lost this case as well and had to pay Randi's legal fees.In April 1992 Geller sued Prometheus Books for $4 million alleging libel in two other books. This suit was thrown out in 1994 and the judge ordered Geller to pay $20,272.89 in legal fees.After Geller's three lawsuits, Randi said he "never paid even one dollar or even one cent to anyone who ever sued me, and certainly not to Geller".
