OpenCola is a brand of open-source cola, where the instructions for making it are freely available and modifiable. Anybody can make the drink, and anyone can modify and improve on the recipe. It was launched in 2001 by free software P2P company Opencola, to promote their open-source software concept.

EPUB is an e-book file format that uses the ".epub" file extension. The term is short for electronic publication and is sometimes styled ePub. EPUB is supported by many e-readers, and compatible software is available for most smartphones, tablets, and computers. EPUB is a technical standard published by the International Digital Publishing Forum (IDPF). It became an official standard of the IDPF in September 2007, superseding the older Open eBook standard.

The Book Industry Study Group endorses EPUB 3 as the format of choice for packaging content and has stated that the global book publishing industry should rally around a single standard. The EPUB format is implemented as an archive file consisting of XHTML files carrying the content, along with images and other supporting files. EPUB is the most widely supported vendor-independent XML-based (as opposed to PDF) e-book format; that is, it is supported by almost all hardware readers, except for Kindle.

Zooko's triangle is a trilemma of three properties that are generally considered desirable for names of participants in a network protocol:

• Human-meaningful: Meaningful and memorable (low-entropy) names are provided to the users.
• Secure: The amount of damage a malicious entity can inflict on the system should be as low as possible.
• Decentralized: Names correctly resolve to their respective entities without the use of a central authority or service.

Kateryna Lohvynivna Yushchenko (Ukrainian: Катерина Логвинівна Ющенко, Russian: Екатерина Логвиновна Ющенко, December 8, 1919, Chyhyryn - died August 15, 2001) was a Ukrainian computer and information research scientist, corresponding member of USSR Academy of Sciences (1976), and member of The International Academy of Computer Science. She developed one of the world's first high-level languages with indirect address in programming, called the Address programming language. Over the period of her academic career, Yushchenko supervised 45 Ph.D students. Further professional achievements include Yushchenko being awarded two USSR State Prizes, The USSR Council of Ministers Prize, The Academician Glushkov Prize, and The Order of Princess Olga. Yushchenko was the first woman in the USSR to become a Doctor of Physical and Mathematical Sciences in programming.

The Scunthorpe problem is the unintentional blocking of websites, e-mails, forum posts or search results by a spam filter or search engine because their text contains a string of letters that appear to have an obscene or otherwise unacceptable meaning. Names, abbreviations, and technical terms are most often cited as being affected by the issue.

The problem arises since computers can easily identify strings of text within a document, but interpreting words of this kind requires considerable ability to interpret a wide range of contexts, possibly across many cultures, which is an extremely difficult task. As a result, broad blocking rules may result in false positives affecting innocent phrases.

Plankalkül (German pronunciation: [ˈplaːnkalkyːl]) is a programming language designed for engineering purposes by Konrad Zuse between 1942 and 1945. It was the first high-level programming language to be designed for a computer.

Kalkül is the German term for a formal system—as in Hilbert-Kalkül, the original name for the Hilbert-style deduction system—so Plankalkül refers to a formal system for planning.

In computer networking, IP over Avian Carriers (IPoAC) is a proposal to carry Internet Protocol (IP) traffic by birds such as homing pigeons. IP over Avian Carriers was initially described in RFC 1149, a Request for Comments (RFC) issued by the Internet Engineering Task Force (IETF), written by D. Waitzman, and released on April 1, 1990. It is one of several April Fools' Day Request for Comments.

Waitzman described an improvement of his protocol in RFC 2549, IP over Avian Carriers with Quality of Service (1 April 1999). Later, in RFC 6214—released on 1 April 2011, and 13 years after the introduction of IPv6—Brian Carpenter and Robert Hinden published Adaptation of RFC 1149 for IPv6.

IPoAC has been successfully implemented, but for only nine packets of data, with a packet loss ratio of 55% (due to operator error), and a response time ranging from 3,000 seconds (≈54 minutes) to over 6,000 seconds (≈1.77 hours). Thus, this technology suffers from poor latency. Nevertheless, for large transfers, avian carriers are capable of high average throughput when carrying flash memory devices, effectively implementing a sneakernet. During the last 20 years, the information density of storage media and thus the bandwidth of an avian carrier has increased 3 times as fast as the bandwidth of the Internet. IPoAC may achieve bandwidth peaks of orders of magnitude more than the Internet when used with multiple avian carriers in rural areas. For example: If 16 homing pigeons are given eight 512 GB SD cards each, and take an hour to reach their destination, the throughput of the transfer would be 145.6 Gbit/s, excluding transfer to and from the SD cards.

The British Post Office scandal is a widespread and long-lasting series of individual miscarriages of justice which, between 1999 and 2015, involved over 700 subpostmasters being wrongly convicted of theft, false accounting and fraud when shortfalls at their branches were in fact due to errors of the Post Office's Horizon accounting software. In 2019, the High Court ruled that the Horizon system was faulty and in 2020 the government established a public inquiry. Courts began to quash convictions from 2010. As of January 2024, some victims are still fighting to have their convictions overturned and receive compensation, the public inquiry is ongoing, and the Metropolitan Police is investigating the Post Office for potential fraud offences.

The Horizon accounting system was developed by ICL Pathway, owned by the Japanese company Fujitsu. In 1999, the Post Office started to roll out the new software to its branch and sub-offices, the latter managed by subpostmasters on a self-employed basis under contracts with the Post Office. Almost immediately, some subpostmasters noticed the new system reporting false shortfalls, sometimes for thousands of pounds. The Post Office insisted that the system was robust and, when shortfalls occurred, prosecuted the subpostmasters or forced them to make up the amount. The impact of court cases, criminal convictions, imprisonment, loss of livelihood and homes, debt and bankruptcy took a heavy toll on victims and their families, leading to stress, illness, divorce and, in at least four cases, suicide. In May 2009, Computer Weekly broke the story about problems with Horizon software and in September 2009 subpostmaster Alan Bates set up the Justice for Subpostmasters Alliance (JFSA). In 2012, as a result of pressure from campaigners and Members of Parliament, the Post Office appointed forensic accountants Second Sight to conduct an investigation into Horizon. The investigators concluded that Horizon contained faults that could result in accounting discrepancies, but the Post Office insisted that there were no system-wide problems with the software.

In 2019 a group of 555 subpostmasters led by Bates won a group action brought in court against the Post Office, with the judge ruling that Horizon contained bugs, errors and defects. The Post Office agreed to settle out of court for £58 million. The subpostmasters' legal costs amounted to £47 million of, leaving them with only about £20,000 each. The government later agreed to supplement the settlement, as they were excluded from the compensation scheme set up by the Post Office for other victims of the scandal. The first convictions to be quashed were those of six subpostmasters who had been convicted in magistrates' courts and whose appeals were heard at Southwark Crown Court in December 2020. In allowing the appeal by 39 subpostmasters in April 2021, the Court of Appeal judges ruled that in cases that relied on Horizon data a fair trial was not possible. Further appeal cases followed.

In September 2020, the government established the Post Office Horizon IT Inquiry, chaired by retired judge Sir Wyn Williams, to look into the implementation and failings of the Horizon system that led to the prosecution of subpostmasters and termination of their contracts. Evidence was due to be heard from subpostmasters, the Post Office, UK Government Investment, the Department for Business and Trade, and others.

A four-part television drama, Mr Bates vs the Post Office, was broadcast on ITV in January 2024, after which the scandal became a major news story and political issue.
