The Noida double murder case refers to the murder of 14-year-old girl Aarushi Talwar and 45-year-old Hemraj Banjade, a domestic worker, employed by her family in Noida, India.
 The two were killed on the night of 15–16 May 2008 at Aarushi's home.
 The case aroused public interest as a whodunit story, and received heavy media coverage.
 The sensational media coverage, which included salacious allegations against Aarushi and the suspects, was criticized by many as a trial by media.

 Produced by Ray Haboush, the film stars Corey Landis, Victoria Summer, Krash Miller, Stuart Rigby and Keith Reay.

Lindenstraße (literally "Lime Street") is a German television drama series, broadcast by Das Erste.
 The first episode aired on 8 December 1985 and since then new episodes have aired weekly.
 Its current timeslot on Das Erste is Sundays at 18:50.
 The events of the Sunday episode usually take place on the Thursday before the show, based on the TV station's original plan of airing the episodes Thursday night.
 Prior of the start of the show, the timeslot was switched to Sunday evening but the Thursday remained the day the events usually take place as the show shall feature the daily life routine of the protagonists on a working day.
 Exceptions are the so-called holiday episodes that take place on Sunday, such as for Christmas and Easter and also on important election days (especially the election to the German Bundestag).
Teknivals (the word is a portmanteau of the words tekno and festival) are large free parties which take place worldwide.
 They take place most often in Europe and are often illegal under various national or regional laws.
 They vary in size from dozens to thousands of people, depending on factors such as accessibility, reputation, weather, and law enforcement.
 The parties often take place in venues far away from residential areas such as squatted warehouses, empty military bases, beaches, forests or fields.
 The teknival phenomenon is a grassroots movement which has grown out of the rave, UK traveller and Burning Man scenes and spawned an entire subculture.
 Summer is the usual season for teknivals.
Aniversario: Never Compromise was a professional wrestling internet pay-per-view (iPPV) event produced by the Chikara promotion, that took place on June 2, 2013, at the Trocadero Theatre in Philadelphia, Pennsylvania.
 The event marked Chikara's fourth iPPV, third to take place at the Trocadero Theatre and the promotion's only event to take place in Philadelphia in 2013.
 Much like the previous iPPV, Under the Hood, Aniversario: Never Compromise also aired through Smart Mark Video.
 Aniversario: Never Compromise celebrated Chikara's eleventh anniversary and was the first anniversary event to take place on iPPV; in the past, the promotion had celebrated its anniversaries with weekends of two shows.
 The event saw all three Chikara championships being defended with one title change, where Pieces of Hate (Jigsaw and The Shard) defeated 3.0 (Scott Parker and Shane Matthews) for the Campeonatos de Parejas.
 Another major match during the event saw former Campeones de Parejas, Amasis and Ophidian, end their nineteen-month storyline rivalry in a Sarcophagus match.
 The event concluded with a major storyline development, where Chikara's authority figure Wink Vavasseur ended the event and shut down the promotion, while the main event was still going on in the ring, leading to the promotion going inactive for a full year.
The next elections for the President of Croatia are due to take place by direct popular vote on a date between 21 December 2019 and 20 January 2020, with a second round (if necessary) to take place on a date between 4 January 2020 and 3 February 2020 between the two candidates with the largest number of votes in the first round.
 Namely, the Constitution of Croatia states that a presidential election must be held no more than 60 days and no less than 30 days before the expiration of the incumbent president's term.
 They will be the seventh presidential elections since the first direct ones were held in 1992.
Presidential elections were held in Haiti on 25 October 2015, alongside local elections and the second round of the legislative elections.
 Incumbent President Michel Martelly was constitutionally barred from running.
 As no candidate received a majority of the vote in the first round, a runoff was to be held on 27 December 2015.
 Voter turnout was reportedly 28.8%.
 On 22 December the Conseil Electoral Provisoire announced that the runoff has been postponed indefinitely.
 However, on 1 January 2016 President Michel Martelly announced that the runoff would be held on 17 January, but on 7 January the President changed the date to 24 January.
 On 20 January, Jude Célestin issued a statement that calls "whatever the person who will participate in this January 24 [runoff], is a traitor to the Nation".
 Because of rioting and electoral violence, on 22 January the CEP decided to postpone the second round again, with no specific date given, even after President Michel Martelly confirmed the previous day in a nationwide speech that the election should still take place.
 The run-off date was later agreed to take place on 24 April 2016.
 However, according to Reuters and several other sources, the runoff is postponed again with an indeterminate date most likely after October 2016.
 United Nations Secretary-General has expressed deep concern that the agreed upon date for holding elections in Haiti was not met and that no alternate electoral calendar was announced.
The Trojan horse defense is a technologically based take on the classic SODDI defense, believed to have surfaced in the UK in 2003.
 The defense typically involves defendant denial of responsibility for (i) the presence of cyber contraband on the defendant's computer system; or (ii) commission of a cybercrime via the defendant's computer, on the basis that a malware (such as a Trojan horse, virus, worm, Internet bot or other program) or on some other perpetrator using such malware, was responsible for the commission of the offence in question.
The WTA 125K series is the secondary professional tennis circuit organised by the Women's Tennis Association.
 The 2016 WTA 125K series calendar consists of eight tournaments, each with a total prize fund of $125,000.
 After 2015, the Nanchang event was upgraded to a WTA International level tournament, and with new events starting in San Antonio, West Hempstead and Bol.
 The planned tournament in West Hempstead was then cancelled, and the tournament scheduled to take place in Carlsbad, California was moved to Oahu, Hawaii.
 Following the death of the Thai king Bhumibol Abdulyadej, the event due to take place in Hua Hin was also cancelled, in accordance with Thai tradition that sporting events cannot take place in the month after a monarch's death.
