Reflecting On Margaret Hamilton: 50 Years After Apollo 11

-

In celebration of the 50th anniversary of the first Apollo moon landing, Google created a 1.4-square-mile portrait of NASA software developer Margaret Hamilton using more than 107,000 mirrors from the Ivanpah Solar Facility in the Mojave Desert, a solar thermal power plant with a gross capacity of 392 megawatts.

The fields of heliostat mirrors (173,500 in total) ordinarily focus sunlight on receivers located on the solar power towers, which subsequently generate steam to drive steam turbines. The facility was first connected to the electrical grid in September 2013 before formally opening in February 2014, during which it was the world’s largest solar thermal power station. Ivanpah was developed by BrightSource Energy and Bechtel, with Google contributing $168 million towards its $2.2 billion in costs. Google no longer invests in the facility, however, due to the decline of the price of photovoltaic systems.

The facility has historically taken steps to avoid disrupting the natural wildlife, which includes desert tortoises. The effect of mirror glare on airplane pilots, water concerns, and collisions with birds has also been addressed by the operators of the installation.

According to Google, the image was larger than Central Park and could be seen a mile above sea level. The mirrors are all attached to a rotating mount that maneuvers the mirrors in order to create lighter and darker shades to make up the image.

The Apollo 11 mission, manned by Buzz Aldrin, Neil Armstrong, and Michael Collins, was the first to bring humans to the moon in 1969. Hamilton‘s role in the team included programming the in-flight software for all of NASA’s Apollo missions. She had also worked on satellite tracking software for the Air Force through Lincoln Lab (started by the Massachusetts Institute of Technology) and later joined the Charles Stark Draper Laboratory. It was, however, her work on creating computer systems to predict and track weather systems for use in anti-aircraft air defenses that made her a candidate for a lead developer role at NASA.

Takeaways from the outcry over Dior’s Johnny Depp perfume ad: Tuesday Wake-Up Call

-
Welcome to Ad Age’s Wake-Up Call, our daily roundup of advertising, marketing, media and digital news. You can sign up to get an audio version of this briefing on your Alexa device. Dior pulls a perfume ad starring Johnny Depp Yet another luxury brand just had to backtrack after a culturally insensitive move. Dior on Friday pulled an ad for its “Sauvage” perfume, as Business of Fashion reports ; the spot starred Johnny Depp playing guitar in the desert while a Native American dancer, Canku One Star, performed in traditional dress. The company portrayed the spot as “an authentic journey deep into the Native American soul.” But the brand was quickly accused of cultural appropriation. Critics seemed most troubled by the juxtaposition of Native American imagery with the word "Sauvage"—which means “wild” in French, but which also evokes the history of labeling indigenous groups as “savages.”  LVMH-owned Parfums Christian Dior had apparently tried to proceed cautiously. It coo

When the coronavirus infodemic strikes

Social media sites are stepping up their efforts in the war against misinformation… specifically, the coronavirus/COVID-19 infodemic . There’s a seemingly endless stream of potentially dangerous misinformation flying around online related to the COVID-19 pandemic, and that could have fatal results. It’s boomtown in fake-news land riding high on the wave of people being left with their tech devices 24/7. I myself regularly see everything posted online from “hand gel is an immunizer” (nope) and “children can’t be affected” (not true) to “UK rules mean domestic abuse survivors have to stay with their abusive spouse” (absolutely not true at all and hugely dangerous to claim).  We even have engineers being spat on thanks to 5G conspiracy theories potentially resulting in transmission of coronavirus . Turns out a global pandemic is a lightning rod for pushing people to conspiracy theories galore, to the extent that some folks have to go hunting for guides to wean their family members a

Patch, Or Your Solid State Drives Roll Over And Die

Expiration dates for computer drives? That’s what a line of HP solid-state drives are facing as the variable for their uptime counter is running out. When it does, the drive “expires” and, well, no more data storage for you! There are a series of stages in the evolution of a software developer as they master their art, and one of those stages comes in understanding that while they may have a handle on the abstracted world presented by their development environment they perhaps haven’t considered the moments in which the real computer that lives behind it intrudes. Think of the first time you saw an SQL injection attack on a website, for example, or the moment you realised that a variable type is linked to the physical constraints of the number of memory locations it has reserved for it. So people who write software surround themselves with an armoury of things they watch out for as they code, and thus endeavour to produce software less likely to break. Firmly in that arena is the size
