Ada Lovelace Day
A portrait of Ada Lovelace, based on an original watercolour portrait by Alfred Edward Chalon (1780 – 1860), that has been modified into a woodcut-style graphic by Colin Adams, for the Ada Initiative. It has been converted into SVG format by Fred the Oyster then colourized by Kaldari. The original artwork is in the public domain, and this final Creative Commons derivative has been available in this form since 2011-10-15.

Today is Tuesday, 2021-10-12. Because it is the second Tuesday in October, it is Ada Lovelace Day.

The micro-story behind this posting is that Ada Lovelace (1815 – 1852) collaborated with Charles Babbage (1791 – 1871) on his Analytical Engine. In 1843, she was the first person to publish a computer program. It generated Bernoulli numbers. Lovelace is also considered the first person to foresee the creative potential of the Analytical Engine, especially its ability to create music and art. The date selected for Ada Lovelace day is arbitrary. This day is one that could be one used by people with programming skills to serve humankind in various ways. In many places, it is also a school day, although not this year, and many other years where I live, as a week long autumn school break is being held.

For those wanting more information about Ada Lovelace, one place to begin is her Wikipedia article. In additional to a biography, it also provides other sources of information about her, including books, plays and videos.

At one level this day attempts to raise the profile of women in Science, Technology, Engineering and Mathematics (STEM). Some want to use STEAM, by adding Art. In my time as a teacher of technology, Ada Lovelace day was an opportunity to encourage female students to investigate STEAM, where they might be able to bypass some of those headstrong members of another, weaker gender. This day does not supersede or in any way compete with the International Women’s Day on 03-08,

In terms of the more technical aspects of computing there are many other days that can be celebrated, World computer day is 02-15. It was first celebrated in 2021, with a focus on 75 year old Eniac, described by some as the first programmable, electronic, general-purpose digital computer. At a more practical level, the second Monday in February, is designated the (American) National Clean Out Your Computer Day. Many people have issues regarding the storage of data on their computers, including the taking of regular backups. However, there is also a World Backup Day on 03-31, which could be a better day to focus on such issues.

For those who need more computing days: (Apple) Macintosh Computer Day = 01-24; World Password Day = 05-05; System Administrator Appreciation Day = 07-30; Computer Security Day = 11-30; Computer Literacy Day = 12-02, and National Download Day = 12-28.

Dates in the weblog follow International Standard ISO 8601 formats. Generally, of the form YYYY-MM-DD, however in this specific post there are many in the MM-DD format. ISO 8601 is the only format that the Government of Canada and Standards Council of Canada officially recommend for all-numeric dates. It is my experience that about half the Canadian population uses the American MM-DD-YYYY format, while the other half uses DD-MM-YYYY, necessitating the need for ISO 8601. However, usage differs with context. See:
