Bulgaria
Bulgaria (; bg, България, Bǎlgariya), officially the Republic of Bulgaria,, ) is a country in Southeast Europe. It is situated on the eastern flank of the Balkans, and is bordered by Romania to the north, Serbia and North Macedonia to the west, Greece and Turkey to the south, and the Black Sea to the east. Bulgaria covers a territory of , and is the sixteenth-largest country in Europe. Sofia is the nation's capital and largest city; other major cities are Plovdiv, Varna and Burgas. One of the earliest societies in the lands of modern-day Bulgaria was the Neolithic Karanovo culture, which dates back to 6,500 BC. In the 6th to 3rd century BC the region was a battleground for ancient Thracians, Persians, Celts and Macedonians; stability came when the Roman Empire conquered the region in AD 45. After the Roman state splintered, tribal invasions in the region resumed. Around the 6th century, these territories were settled by the early Slavs. The Bulgars, led by Asp ...

Frances Elizabeth Holberton (March 7, 1917 – December 8, 2001) was an American computer scientist who was one of the six original programmers of the first general-purpose electronic digital computer, ENIAC. The other five ENIAC programmers were Jean Bartik, Ruth Teitelbaum, Kathleen Antonelli, Marlyn Meltzer, and Frances Spence. Holberton invented breakpoints in computer debugging. Early life and education Holberton was born Frances Elizabeth Snyder in Philadelphia, Pennsylvania in 1917. Her father was John Amos Snyder (1884-1963), her mother was Frances J. Morrow (1892-1981) and she was born as the third child in a family of 8 children. Holberton studied journalism, because its curriculum let her travel far afield. Journalism was also one of the few fields open to women as a career in the 1940s. On her first day of classes at the University of Pennsylvania, her math professor asked her if she wouldn't be better off at home raising children. Career During World War 2 while t ...
