Bloomberg on some promising trends in U.S. energy production.
For the first time, widespread adoption of renewables is effectively lowering the capacity factor for fossil fuels. That’s because once a solar or wind project is built, the marginal cost of the electricity it produces is pretty much zero—free electricity—while coal and gas plants require more fuel for every new watt produced. If you’re a power company with a choice, you choose the free stuff every time.
It’s a self-reinforcing cycle. As more renewables are installed, coal and natural gas plants are used less. As coal and gas are used less, the cost of using them to generate electricity goes up. As the cost of coal and gas power rises, more renewables will be installed.
From a concept kitchen developed by IKEA, IDEO, and design students from Lund University and Eindhoven University of Technology.
While we often see smart refrigerators as in concept kitchens, IKEA and the designer believe that fridges will become obsolete in the future due to their energy inefficiency. Rather, people will store food much as how they have done so in the past—using materials that are naturally insular, such as cooling ceramic, to keep items as fresh as possible. People will no longer buy groceries on a weekly basis, but with automatic delivery from drones and the like, fresh food will be just as easy to get on demand.
The film world received dreadful news this week when it was discovered that the famed Belgian filmmaker and pioneer of modern feminist cinema Chantal Akerman had died. She is well known for her breakout film, directed at age 25, Jeanne Dielman, 23 quai du Commerce, 1080 Bruxelles (1975), which depicts several hours in the domestic life of a single mother who is also a sex worker.
Mitigating the sad circumstance of Akerman’s passing, the Criterion Collection, an American film distribution company known for its discriminating supply of virtuoso filmmakers, has made its entire catalogue of Akerman’s work available for viewing on Hulu for free.
Do check out Jeanne Dielman. It’s very slow paced, but that pace feels deliberate and effective. The subtlety of the photography and sound design manages to hold your attention for 3-plus hours. However, you may want to seek out the film elsewhere if you don’t have a paid Hulu account. The relentless advertising significantly shifts the viewing experience. I appreciate the gesture of the Criterion Collection licensing this as they have, but such a quiet, poised film easily gets overwhelmed by schlocky ads.
As a coding exercise for a course I’m teaching this semester I created this single-serving site serializing Moby Dick into tiny individual texts. Remember single-serving sites? Sadly many of those domains have expired, but one of the best of them—Barack Obama Is Your New Bicycle—is still there, if a bit quaint. I ruthlessly stole the design.
Theory of Everything recently posted an addendum to last year’s Enchanting by Numbers. Both episodes are very worthwhile, and both include the same segment talking about how misunderstood Facebook algorithms are to most of its users.
Be sure to listen to the interview with Suw Charman-Anderson, founder of Ada Lovelace Day, which is today! That part starts at 14:30 in part 1.
Margaret Hamilton oversaw the guidance software on the Apollo program. Thanks to sophisticated error-handling in that code, her engineering efforts prevented an abort of the Apollo 11 landing.
Three minutes before the Lunar lander reached the Moon’s surface, several computer alarms were triggered. The computer was overloaded with incoming data, because the rendezvous radar system (not necessary for landing) updated an involuntary counter in the computer, which stole cycles from the computer. Due to its robust architecture, the computer was able to keep running; the Apollo onboard flight software was developed using an asynchronous executive so that higher priority jobs (important for landing) could interrupt lower priority jobs.
This was on a 2 MHz machine with 1 MB of RAM. Even the term software engineering was coined by Hamilton, who also helped develop “concepts of asynchronous software, priority scheduling, end-to-end testing, and human-in-the-loop decision capability.”
A safe mantra to keep in mind with software is “all software has bugs,” which so often means “don’t expect too much.” Margaret Hamilton was instrumental in creating processes to ensure that software can systematically accommodate surprises and continue functioning as expected.
A fan of the space program, Kipp Teague, has uploaded a huge trove of Apollo mission photo scans onto Flickr. They’re organized into albums, but rather overwhelming as a collection, unless you want to just page through thousands of space photos (which, I mean, yeah why not?).
Digg has posted a smaller “best of” selection if you want to see just the highlights.
Does your lifestyle prevent you from qualifying for insurance discounts?
Do you lack sufficient time for exercise or have limited access to sports facilities?
Maybe you just want to keep your personal data private without having to pay higher insurance premiums for the privilege?
Unfit Bits provides solutions. At Unfit Bits, we are investigating DIY fitness spoofing techniques to allow you to create walking datasets without actually having to share your personal data. These techniques help produce personal data to qualify you for insurance rewards even if you can’t afford a high exercise lifestyle.
Photogrammar is an impressive database from Yale “organizing, searching, and visualizing the 170,000 photographs from 1935 to 1945 created by the United States Farm Security Administration and Office of War Information (FSA-OWI).”
No known dialect of Ant employs any verbal person except the third person singular and plural and the first person plural. In this text, only the root forms of the verbs are used; so there is no way to decide whether the passage was intended to be an autobiography or a manifesto.
Long are the tunnels. Longer is the untunneled. No tunnel reaches the end of the untunneled. The untunneled goes on farther than we can go in ten days [i.e., forever]. Praise!
The mark translated “Praise!” is half of the customary salutation “Praise the Queen!” or “Long live the Queen!” or “Huzza for the Queen!”—but the word/mark signifying “Queen” has been omitted.
