Ghana Code Club. The Ghana Code Club is an after-school programme in Ghana that teaches children computer programming skills. The programme was founded by Ernestina Edem Appiah, and the programme is organized in various schools by Healthy Career Initiative, a nonprofit organisation in Ghana. Healthy Career Initiative was also founded by Appiah, in 2007. Ghana Code Club is a digital fun club that is being organized in schools in Ghana for children between the ages of 8–17. It is an after-school extracurricular programme.

As of January 2016 in Ghana, the present information communications technology curriculum in Ghana does not include learning activities for technology. The club encourages children to attain modern skills in computer technology to help them with future careers. Some of the activities include learning how to create websites, animations and video games. In January 2016, the programme began operations in five schools, and the organisation is prepared to expand into most schools in Ghana in 2016, with a goal of educating at least 20,000 children.

Challenges faced by the Ghana Code Club includes problems with internet connectivity in Ghana, and access to capital and computer equipment. As a result, a significant portion of the classes are presently taught on paper with printouts.

History
The founder and CEO of Ghana Code Club is Ernestina Edem Appiah,  her interest  was initiated by an article she read about children in the United Kingdom learning coding (computer programming). Appiah was one of the BBC's 100 Women.

Butalene. Butalene is a polycyclic hydrocarbon composed of two fused cyclobutadiene rings. A reported possible synthesis of it involves an elimination reaction from a Dewar benzene derivative. The structure itself can be envisioned as benzene with an internal bridge, and calculations indicate it is somewhat less stable than the open 1,4-didehydrobenzene biradical, the valence isomer in which that bridged bond is broken.

Structure and bonding 

Ab initio calculations indicate butalene has a planar geometry and, in keeping with a planar structure with 6 π-electron configuration, is aromatic. Thus, the most significant π bonding interactions involve conjugation around the periphery of the whole six-atom structure, similar to benzene, rather than cross-ring resonance along the bridging bond. Significant resonance around one or the other four-membered ring alone would be a less-stable antiaromatic form, as is seen in cyclobutadiene itself.

Bob Belleville. Robert L. Belleville is an American computer engineer who was an early head of engineering at Apple from 1982 until 1985.

Belleville worked at Xerox, where he was a primary designer of the hardware for the Xerox Star. Steve Jobs is said to have invited him to join Apple by saying, "Everything you've ever done in your life is shit, ... so why don't you come work for me?" In May 1982, he became software manager for the Macintosh 128K; in August that year he became engineering manager of the Macintosh division. As Apple Director of Engineering, he played a major role in developing the LaserWriter. He resigned from Apple in summer 1985 after Jobs announced his resignation, and later worked at Silicon Graphics.

In Alex Gibney's documentary Steve Jobs: The Man in the Machine, Belleville said that the pressure of working at Apple had ended his marriage and that Jobs "[was always apparently] seducing you, vilifying you, or ignoring you", but he cried when he recalled working for him.

Glenn L. Martin Bomber Plant. The Glenn L. Martin Bomber Plant (also known as Air Force Plant 1) was an aircraft manufacturing facility in the central United States, located at Offutt Field, Nebraska, south of Omaha. Adjacent to suburban Bellevue in Sarpy County, the plant was operational during World War II, from 1942 to 1945.

Background
In 1940, as American involvement in World War II loomed, the U.S. Army Air Corps chose Offutt Field as the site for a new bomber plant that was to be operated by the Glenn L. Martin Company. The plant's construction included a  concrete runway, six large hangars, and a  aircraft assembly building.

B-26
Martin began producing its bombers in January 1942, with the plant reaching full-scale production 8 June 1942.  Initially producing B-26 Marauder medium bombers, 1,585 Marauders were built at this plant.  The Army Air Forces designated the military personnel assigned to the plant as the 83d Army Air Force Technical Training Detachment, later re-designated as Sq L, Government-Owned Assembly Plant No. 1, WD-101, Army Air Forces Material Command. President Franklin D. Roosevelt toured the plant on 26 April 1943 with Nebraska Governor Dwight Griswold and plant owner Glenn L. Martin.

B-29
Production switched to B-29 Superfortresses in 1944, and 531 of the Boeing-designed very heavy bombers were produced at the Nebraska site. Among these were the Enola Gay and Bockscar, the aircraft that dropped the first atomic weapons to be used in a military action (against the cities of Hiroshima and Nagasaki, Japan).  Both were built and modified (Silverplate) at the base. Paul Tibbets personally selected the Enola Gay from the assembly line.

Production ended on 18 September 1945, when the last B-29 rolled out of the assembly building. With the manufacturing plant's closure, custody of the airfield and ground facilities were assumed by the 4131st Army Air Force Base Unit, Air Materiel Command.

The building's use continued at Offutt AFB into the 21st century.

Demolition
Due its proximity to the main runway at Offutt, the building was scheduled to be demolished as a safety risk.

Code: Debugging the Gender Gap. CODE: Debugging the Gender Gap is a 2015 documentary by Robin Hauser Reynolds. It focuses on the lack of women and minorities in the field of software engineering. It premiered on April 19, 2015 at the Tribeca Film Festival in New York. The film focuses on inspiring young girls to pursue careers in computer science by profiling successful women in computer programming, such as, Danielle Feinberg of Pixar, Aliya Rahman of Code for Progress, and Julie Ann Horvath. By profiling and displaying the careers of these women, the film makers hope to show that computer science can be creative, lucrative, and rewarding.

The film traces the history of women in the U.S. technology industries, from the work of Ada Lovelace, Grace Hopper, and the women of ENIAC. It then follows the decline of women graduates in mathematics and computer science during the 1980s, linking the phenomenon to the release of the 1983 film WarGames, and a cultural shift that depicted men and boys as technology workers, and increasing hostility for women and girls in the tech industries. Additionally, the film highlights the work of women in the field, by featuring interviews with women in the tech industry, such as Kimberly Bryant (founder of Black Girls Code), Debbie Sterling (founder of GoldieBlox), Maria Klawe (president of Harvey Mudd College), and Danielle Feinberg (director of photography at Pixar).

Fundraising 
Funding for the film was partially raised via Indiegogo and Reynolds was able to successfully receive additional funding from corporations like CapitalOne, MasterCard, Ericsson, NetApp, Qualcomm, and Silicon Valley Bank.

Reception 
The general reception of the film by popular press has been positive. Stephen Cass of IEEE Spectrum, stated of the film: "Code doesn't have all the answers, of course. But ultimately, it does make a good case that everyone should think deliberately about diversity in their hiring." Some criticism has focused on the apparent lack of attention paid to the Gamergate controversy, and the work and experience of women in the gaming industries.

Graham Winfrey of Inc. magazine wrote, "CODE makes a compelling case that the lack of women in tech poses a significant threat to America's future."
