Michael J. (Mike) Karels (August 2, 1956 – June 2, 2024) was an American software engineer and one of the key figures in history of BSD UNIX.

In 1993, the USENIX Association gave a Lifetime Achievement Award (Flame) to the Computer Systems Research Group at University of California, Berkeley, honoring 180 individuals, including Karels, who contributed to the CSRG's 4.4BSD-Lite release.

In February 1992 Karels moved to BSDi (Berkeley Software Design) and designed BSD/OS, which, for years, was the only commercially available BSD style Unix on Intel platform. BSDi's software assets were bought by Wind River in April 2001, and Karels joined Wind River as the Principal Technologist for the BSD/OS platform.

Following his time at Wind River, Karels joined Secure Computing Corporation in 2003 as a Sr. Principal Engineer. Secure Computing used BSD/OS as the basis for SecureOS, the operating system of its Sidewinder firewall, later known as McAfee Firewall Enterprise. However, BSD/OS development had ceased, so Karels was involved in transitioning SecureOS to use FreeBSD as its base, and porting its unique features over to the new kernel. Secure Computing and the Sidewinder firewall team went through a series of acquisitions and spinoffs, including McAfee, Intel, and Forcepoint, so while Karels appeared to have several different jobs from that point onward, he had remained in roughly the same role from 2003 until his retirement in 2021.

The Sidewinder product was eventually discontinued, though Karels fed some SecureOS changes back into the main FreeBSD codebase. Karels officially became a FreeBSD committer in 2017. He continued working on FreeBSD in his spare time following retirement.

A 2019 report by the National Center for Education Statistics determined that mid to high literacy in the United States is 79% with 21% of American adults categorized as having "low level English literacy," including 4.1% classified as "functionally illiterate" and an additional 4% that could not participate. According to the U.S. Department of Education, 54% of adults in the United States have prose literacy below the 6th-grade level.

In many nations, the ability to read a simple sentence suffices as literacy, and was the previous standard for the U.S. The definition of literacy has changed greatly; the term is presently defined as the ability to use printed and written information to function in society, to achieve one's goals, and to develop one's knowledge and potential.

The United States Department of Education assesses literacy in the general population through its National Assessment of Adult Literacy (NAAL). The NAAL survey defines three types of literacy:

• prose literacy: the knowledge and skills needed to search, comprehend, and use continuous texts. Examples include editorials, news stories, brochures, and instructional materials.
• document literacy: the knowledge and skills needed to search, comprehend, and use non-continuous texts in various formats. Examples include job applications, payroll forms, transportation schedules, maps, tables, and drug and food labels.
• quantitative literacy: the knowledge and skills required to identify and perform computations, either alone or sequentially, using numbers embedded in printed materials. Examples include balancing a checkbook, figuring out tips, completing an order form, or determining an amount.

Modern jobs often demand a high level of literacy, and its lack in adults and adolescents has been studied extensively.

According to a 1992 survey, about 40 million adults had Level 1 literary competency, the lowest level, comprising understanding only basic written instructions. A number of reports and studies are published annually to monitor the nation's status, and initiatives to improve literacy rates are funded by government and external sources.

Some writers have had prolific careers with hundreds of their works being published. While some best-selling authors have written a small number of books that have sold millions of copies, others have had lengthy careers and maintained a high level of output year after year. Dame Agatha Christie, the most-published novelist in history, is estimated to have sold 4 billion books, having written 69 novels and 19 plays. Her works were published between 1920 and 1976, equating to around three publications every two years. Dame Barbara Cartland has also sold millions of copies of her books but wrote many more than Christie. She spent 80 years as a novelist with 722 books published, averaging one book released every 40 days of her career. While Cartland wrote a significant number of full-length novels, other authors have been published many more times but have specialised in short stories. Spanish author Corín Tellado wrote over 4,000 novellas, selling 400 million copies of her books.

Not all authors work alone. Groups of writers, sometimes led by one central figure, have published under shared pseudonyms. The Stratemeyer Syndicate, started by Edward Stratemeyer in 1905, created numerous book series including 190 volumes of The Hardy Boys and 175 volumes of Nancy Drew. More than 1,300 books were published by the group, and although Edward L. Stratemeyer wrote several hundred, he also employed ghostwriters to keep up with the demand. These writers were given storylines and strict guidelines to follow to ensure a level of consistency within each series. Amongst the writing team was Howard R. Garis, who contributed several hundred books to the collection, one of the most active authors. Sales were estimated at over two hundred million copies before the syndicate was sold to Simon & Schuster in 1984.

Most authors carefully craft their work, writing and rewriting several times before publication. Some authors simply use pen and paper, while others such as Isaac Asimov spent hours at a stretch working at a typewriter. Philip M. Parker, by one measure the world's most prolific author, has an entirely different approach. Parker has over 200,000 titles listed on Amazon.com, having developed an algorithm to gather publicly available data and compile it into book form. The computer-generated nature of the books is not detailed on the sales page and the books are printed only when ordered.

"I Have No Mouth, and I Must Scream" is a post-apocalyptic science fiction short story by American writer Harlan Ellison. It was first published in the March 1967 issue of IF: Worlds of Science Fiction.

It won a Hugo Award in 1968. The name was also used for a short story collection of Ellison's work, featuring this story. It was reprinted by the Library of America, collected in volume two (Terror and the Uncanny, from the 1940s to Now) of American Fantastic Tales.

Usenet () is a worldwide distributed discussion system available on computers. It was developed from the general-purpose Unix-to-Unix Copy (UUCP) dial-up network architecture. Tom Truscott and Jim Ellis conceived the idea in 1979, and it was established in 1980. Users read and post messages (called articles or posts, and collectively termed news) to one or more categories, known as newsgroups. Usenet resembles a bulletin board system (BBS) in many respects and is the precursor to Internet forums that are widely used today. Discussions are threaded, as with web forums and BBSs, though posts are stored on the server sequentially. The name comes from the term "users network".

A major difference between a BBS or web forum and Usenet is the absence of a central server and dedicated administrator. Usenet is distributed among a large, constantly changing conglomeration of servers that store and forward messages to one another via "news feeds". Individual users may read messages from and post messages to a local server, which may be operated by anyone.

Usenet is culturally and historically significant in the networked world, having given rise to, or popularized, many widely recognized concepts and terms such as "FAQ", "flame", sockpuppet, and "spam". In the 1990s, before access to the Internet became commonly affordable, Usenet connections via Fidonet's dial-up BBS networks made long-distance or worldwide discussions and other communication widespread, not needing a server, just (local) telephone service.

The Nine Worthies are nine historical, scriptural, and legendary personages who personify the ideals of chivalry established in the Middle Ages, whose lives were deemed a valuable study for aspirants to chivalric status. All were commonly referred to as 'Princes', regardless of their historical titles. In French they are called Les Neuf Preux or "Nine Valiants", giving a more specific idea of the moral virtues they exemplified: those of soldierly courage and generalship. In Italy they are i Nove Prodi.

The Nine Worthies include three pagans (Hector, Alexander the Great and Julius Caesar), three Jews (Joshua, David and Judas Maccabeus) and three Christians (King Arthur, Charlemagne and Godfrey of Bouillon).

A thought-terminating cliché (also known as a semantic stop-sign, a thought-stopper, bumper sticker logic, or cliché thinking) is a form of loaded language, commonly used to quell cognitive dissonance. Depending on context in which a phrase (or cliché) is used, it may actually be valid and not qualify as thought-terminating; it does qualify as such when its application intends to dismiss dissent or justify fallacious logic. Its only function is to stop an argument from proceeding further, in other words "end the debate with a cliche... not a point." The term was popularized by Robert Jay Lifton in his 1961 book Thought Reform and the Psychology of Totalism, who called the use of the cliché, along with "loading the language", as "The language of Non-thought".

The Up series of documentary films follows the lives of ten males and four females in England beginning in 1964, when they were seven years old. The first film was titled Seven Up!, with later films adjusting the number in the title to match the age of the subjects at the time of filming. The documentary has had nine episodes—one every seven years—thus spanning 56 years. The series has been produced by Granada Television for ITV, which has broadcast all of them except 42 Up (1998), which was broadcast on BBC One. Individual films and the series as a whole have received numerous accolades; in 1991, the then-latest instalment, 28 Up, was chosen for Roger Ebert's list of the ten greatest films of all time.

The children were selected for the original programme to represent the range of socio-economic backgrounds in Britain at that time, with the expectation that each child's social class would determine their future. The first instalment was made as a one-off edition of Granada Television's series, World in Action, directed by Canadian Paul Almond, with involvement by "a fresh-faced young researcher, a middle-class Cambridge graduate", Michael Apted, whose role in the initial programme included "trawling the nation's schools for 14 suitable subjects". About the first programme, Apted has said:

It was Paul's film ... but he was more interested in making a beautiful film about being seven, whereas I wanted to make a nasty piece of work about these kids who have it all, and these other kids who have nothing.

After Almond's direction of the original programme, director Michael Apted continued the series with new instalments every seven years, filming material from those of the fourteen who chose to participate. The aim of the continuing series is stated at the beginning of 7 Up as: "Why did we bring these together? Because we wanted a glimpse of England in the year 2000. The union leader and the business executive of the year 2000 are now seven years old." The most recent instalment, the ninth, titled 63 Up, premiered in the UK on ITV in 2019. A special episode featuring celebrity fans of the series, 7 Up & Me, also aired on ITV in 2019. Apted is reported to have said, "I hope to do 84 Up when I'll be 99"; however, he died in 2021.

Trabant (German: [tʁaˈbant] ) is a series of small cars produced from 1957 until 1991 by former East German car manufacturer VEB Sachsenring Automobilwerke Zwickau. Four models were made: the Trabant 500, Trabant 600, Trabant 601, and the Trabant 1.1. The first model, the 500, was a relatively modern car when it was introduced.

It featured a duroplast body on a steel chassis, front-wheel drive, a transverse two-stroke engine, and independent suspension. Because this 1950s design remained largely unchanged until the introduction of the last model, the Trabant 1.1 in 1990, the Trabant became symbolic of the former East Germany's stagnant economy and the collapse of the Eastern Bloc in general. Called "a spark plug with a roof", 3,096,999 Trabants were produced. Older models have been sought by collectors in the United States due to their low cost and fewer restrictions on the importation of antique cars. The Trabant also gained a following among car tuning and rallying enthusiasts.
