Dido ( , ) was, according to ancient Greek and Roman sources, the founder and first queen of Carthage (in modern-day Tunisia). She is primarily known from the account given by the Roman poet Virgil in his epic, Aeneid. In some sources she is also known as Elissa .

Dido Florian Cloud de Bounevialle O'Malley Armstrong, known as Dido (, born 25 December 1971), is an English singer and songwriter. Dido attained international success with her debut album No Angel (1999). It sold over 21 million copies worldwide, and won several awards, including the MTV Europe Music Award for Best New Act, two NRJ Awards for Best New Act and Best Album, and two Brit Awards for Best British Female and Best Album. Her next album, Life for Rent (2003), continued her success with the hit singles " White Flag" and " Life for Rent".

Dido's first two albums are among the best-selling albums in UK Chart history, and both are in the top 10 best-selling albums of the 2000s in the UK. Her third studio album, Safe Trip Home (2008), received critical acclaim but failed to duplicate the commercial success of her previous efforts. She was nominated for an Academy Award for the song " If I Rise". Dido was ranked No. 98 on the Billboard chart of the top Billboard 200 artists of the 2000s (2000–2009) based on the success of her albums in the first decade of the 21st century. Dido made a comeback in 2013, releasing her fourth studio album Girl Who Got Away, which reached the Top 5 in the United Kingdom.

DIDO is a MATLAB optimal control software for solving general-purpose hybrid optimal control problems. Powered by the pseudospectral optimal control theory of Ross and Fahroo, the general-purpose optimal control program is named after Dido, the legendary founder and first queen of Carthage who is famous in mathematics for her remarkable solution to a constrained optimal control problem even before the invention of calculus.

DIDO was a nuclear reactor at the Atomic Energy Research Establishment at Harwell, Oxfordshire in the United Kingdom. It used enriched uranium metal fuel, and heavy water as both neutron moderator and primary coolant. There was also a graphite neutron reflector surrounding the core.

In the design phase, DIDO was known as AE334 after its engineering design number.

DIDO was designed to have a high neutron flux, largely to reduce the time required for testing of materials intended for use in nuclear power reactors. This also allowed for the production of intense beams of neutrons for use in neutron diffraction.

DIDO was shut down in 1990. The primary facilities decommissioning is expected to be complete in 2023 with the reactor decommissioning completed in 2031 and final site clearance achieved in 2064

In all, six DIDO class reactors were constructed based on this design:

• DIDO.
• PLUTO, also at Harwell, first criticality 1957.
• HIFAR ( Australia), first criticality January 1958.
• Dounreay Materials Testing Reactor (DMTR) at Dounreay Nuclear Power Development Establishment in Scotland, first criticality May 1958.
• DR-3 at Risø National Laboratory ( Denmark), first criticality January 1960.
• FRJ-II at Jülich Research Centre ( Germany), first criticality 1962.

HIFAR was the last to shut down, in 2007.
