"🌴Imagine what LA could do if it tied street enhancement to a comprehensive program of shade creation: widening the sidewalks, undergrounding powerlines, cutting bigger tree wells, planting leafy, drought-resistant trees, + making room for arcades, galleries, + bus shelters.🌳"]

"All you have to do is scoot across a satellite map of the Los Angeles Basin to see the tremendous shade disparity. Leafy neighborhoods are tucked in hillside canyons and built around golf courses. High modernist homes embrace the sun as it flickers through labor-intensive thickets of eucalyptus. Awnings, paseos, and mature ficus trees shade high-end shopping districts. In the oceanfront city of Santa Monica, which has a dedicated municipal tree plan and a staff of public foresters, all 302 bus stops have been outfitted with fixed steel parasols (“blue spots”) that block the sun. 9 Meanwhile, in the Los Angeles flats, there are vast gray expanses — playgrounds, parking lots, and wide roads — with almost no trees. Transit riders bake at unsheltered bus stops. The homeless take refuge in tunnels and under highway overpasses; some chain their tarps and tents to fences on Skid Row and wait out the day in the shadows of buildings across the street.

Shade is often understood as a luxury amenity, lending calm to courtyards and tree-lined boulevards, cooling and obscuring jewel boxes and glass cubes. But as deadly, hundred-degree heatwaves become commonplace, we have to learn to see shade as a civic resource that is shared by all. In the shade, overheated bodies return to equilibrium. Blood circulation improves. People think clearly. They see better. In a physiological sense, they are themselves again. For people vulnerable to heat stress and exhaustion — outdoor workers, the elderly, the homeless — that can be the difference between life and death. Shade is thus an index of inequality, a requirement for public health, and a mandate for urban planners and designers.

A few years back, Los Angeles passed sweeping revisions to the general plan meant to encourage residents to walk, bike, and take more buses and trains. But as Angelenos step out of their cars, they are discovering that many streets offer little relief from the oppressive sunshine. Not everyone has the stamina to wait out the heat at an unprotected bus stop, or the money to duck into an air-conditioned cafe. 11 When we understand shade as a public resource — a kind of infrastructure, even — we can have better discussions about how to create it and distribute it fairly.

Yet cultural values complicate the provision of shade. Los Angeles is a low-rise city whose residents prize open air and sunshine. 12 They show up at planning meetings to protest tall buildings that would block views or darken sunbathing decks, and police urge residents in high-crime neighborhoods to cut down trees that hide drug dealing and prostitution. Shade trees are designed out of parks to discourage loitering and turf wars, and designed off streets where traffic engineers demand wide lanes and high visibility. Diffuse sunlight is rare in many parts of Los Angeles. You might trace this back to a cultural obsession with shadows and spotlights, drawing a line from Hollywood noir — in which long shadows and unlit corners represent the criminal underworld — to the contemporary politics of surveillance. 13 The light reveals what hides in the dark.

When I think of Los Angeles, I picture Glendale Boulevard in Atwater Village, a streetcar suburb converted into a ten-lane automobile moonscape. People say they like this street for its wall of low-slung, pre-war storefronts, home to record stores and restaurants. To me, it’s a never-ending, vertiginous tunnel of light. I squint to avoid the glare from the white stucco walls, bare pavement, and car windows. From a climate perspective, bright surfaces are good; they absorb fewer sun rays and lessen the urban heat-island effect. But on an unshaded street they can also concentrate and intensify local sunlight."



"At one time, they did. “Shade was integral, and incorporated into the urban design of southern California up until the 1930s,” Davis said. “If you go to most of the older agricultural towns … the downtown streets were arcaded. They had the equivalent of awnings over the sidewalk.” Rancho homes had sleeping porches and shade trees, and buildings were oriented to keep their occupants cool. The original settlement of Los Angeles conformed roughly to the Law of the Indies, a royal ordinance that required streets to be laid out at a 45-degree angle, ensuring access to sun in the winter and shade in the summer. Spanish adobes were built around a central courtyard cooled by awnings and plants. 15 As the city grew, the California bungalow — a low, rectangular house, with wide eaves, inspired by British Indian hill stations — became popular with the middle class. “During the 1920s, they were actually prefabricated in factories,” Davis said. “There are tens of thousands of bungalows, particularly along the Alameda corridor … that were manufactured by Pacific Ready-Cut Homes, which advertised itself as the Henry Ford of home construction.” 16

All that changed with the advent of cheap electricity. In 1936, the Los Angeles Bureau of Power and Light completed a 266-mile high-voltage transmission line from Boulder Dam (now Hoover Dam), which could supply 70 percent of the city’s power at low cost. Southern Californians bought mass-produced housing with electric heating and air conditioning. By the end of World War II, there were nearly 4 million people living in Los Angeles County, and the new neighborhoods were organized around driveways and parking lots. Parts of the city, Davis said, became “virtually treeless deserts.”"



"It’s easy to see how this hostile design reflected the values of the peak automobile era, but there is more going on here. The destruction of urban refuge was part of a long-term strategy to discourage gay cruising, drug use, and other “shady” activities downtown. In 1964, business owners sponsored another redesign that was intended, in the hyperbolic words of the Los Angeles Times, to finally clear out the “deviates and criminals.” The city removed the perimeter benches and culled even more palms and shade trees, so that office workers and shoppers could move through the park without being “accosted by derelicts and ‘bums.’” Sunlight was weaponized. “Before long, pedestrians will be walking through, instead of avoiding, Pershing Square,” the Times declared. “And that is why parks are built.” 19"



"High-concept architecture is one way to transform the shadescape of Los Angeles. Street trees are another. Unfortunately, the city’s most ubiquitous tree — the iconic Washington robusta, or Mexican fan palm — is about as useful in that respect as a telephone pole.

Palm trees have been identified with southern California since 1893, when Canary Island date palms — the fatter, stouter cousin — were displayed at the Chicago World’s Fair. On the trunk of one of those palms, boosters posted the daily temperatures at a San Diego beach, and the tree itself came to stand for “sunshine and soft air.” In his indispensable history, Trees in Paradise, Jared Farmer traces the palm’s transformation from a symbol of a healthy climate to a symbol of glamour, via its association with Hollywood. 26

Despite that early fame, palm trees did not really take over Los Angeles until the 1930s, when a citywide program set tens of thousands of palms along new or recently expanded roads. They were the ideal tree for an automobile landscape. Hardy, cheap, and able to grow anywhere, palm trees are basically weeds. Their shallow roots curl up into a ball, so they can be plugged into small pavement cuts without entangling underground sewer and water mains or buckling sidewalks. As Farmer puts it, palms are “symbiotic infrastructure,” beautifying the city without making a mess. Plus, as Mary Pickford once pointed out, the slender trunks don’t block the view of storefronts, which makes them ideal for window-shopping from the driver’s seat. The city’s first forester, L. Glenn Hall, planted more than 25,000 palm trees in 1931 alone. 27

Hall’s vision, though, was more ambitious than that. He planned to landscape all of Los Angeles’s roads with 1.2 million street trees. Tall palms, like Washingtonia robusta, would go on major thoroughfares, and side streets would be lined with elm, pine, red maple, liquidambar, ash, and sycamore. A Depression-era stimulus package provided enough funds to employ 400 men for six months. But the forestry department put the burden of watering and maintenance on property owners, and soon it charged for cutting new tree wells, too. Owners weren’t interested. So Hall concentrated his efforts on the 28 major boulevards that would serve the 1932 Olympics — including the now-iconic Ventura, Wilshire, Figueroa, Vermont, Western, and Crenshaw — and committed the city to pay for five years of tree maintenance. That may well have bankrupted the tree planting program, and before long the city was urging property owners to take on all costs, including the trees themselves.

This history partly explains the shade disparity in Los Angeles today. Consider the physical dimensions of a major city street in Hall’s time. Between the expanding road and narrowing sidewalks was an open strip of grass, three to ten feet wide, known as the parkway. Having rejected a comprehensive parks system, Los Angeles relied on these roadside strips to plant its urban forest, but over time the parkways were diminished by various agencies in the name of civic improvements — chiefly, road widening. 29 And the stewardship of these spaces was always ambiguous. The parkways are public land, owned and regulated by the … [more]

Digital Sundial by Mojoptix - Thingiverse
"Tadam !
A Sundial displaying the time inside its shadow, with actual digits ! There is a tiny bit of magic inside...

No batteries, no motor, no electronics... It's all just a really super-fancy shadow show. The shape of the sundial has been mathematically designed to only let through the right sunrays at the right time/angle. This allows to display the actual time with sunlit digits inside the sundial's shadow.

The sundial displays time (with actual digits !!) from 10:00 until 16:00, updating every 20 minutes.
You can precisely adjust the displayed time simply by rotating the gnomon (the magic box that displays time). So you can even adjust for Daylight Saving Time.

You'll also need :
--- an (empty !) jam jar
--- 3x M6 screws, flat head, length = 20 mm
--- 1x M6 screw, flat head, length = 50 mm
--- 4x M6 nuts
--- 4x M6 washer, outside diameter < 14mm"

Ready for Rain — Medium
"It’s raining in Seattle today and tomorrow. This should come as no surprise to those who know the reputation of this part of the world. But in fact, this rain is special. It’s the first storm of the year; a harbinger for a change of season that strikes at the core of how it feels to live in the Pacific Northwest.

You see, this time of year, I want it to rain for days. I want an atmospheric river to roll off the Pacific and slam Seattle with precipitation. I want to look at the weather map and see greens, yellows and oranges. Thankfully, I live in a place that makes the timely arrival of rain an absolute certainty.

It’s not simply the arrival or rain, but the transition to a different environment and way of life. The drear has a certain dark beauty; a low-contrast softness. There’s no need to squint or close the blinds. Even the sound of the rain on our house is music to my ears, a lullaby.

In this feeling, I am not alone:"



"The long, dark Seattle winters do something to me. They make me forget what it’s like when the days are long and warm. The bare trees make it hard to imagine the lush Seattle spring.

And then, just as it becomes too dark for too long, the promise of a sun-kissed rendezvous returns and the great maximization begins again — along with the pressure. It’s a cycle I’ve come to love.

I do look forward to the sun, but it ends just in time, because in my heart, I also love the rain."

"The Weight of Mountains

Here’s a short film by a children’s book illustrator about “the processes by which mountains are created and eventually destroyed, based upon the work of British geographer L. Dudley Stamp.” It’s eye-meltingly gorgeous and starkly scientific. The tone is meditative and incantatory, turning geological terms into epic poetry. If you’ve ever wanted to read John McPhee’s “Annals of the Former World” but only have 11 minutes, watch this."

[Direct link to video: https://vimeo.com/87651855

"This is a short film about the processes by which mountains are created and eventually destroyed. It is based upon the work of British geographer L. Dudley Stamp, and was shot in Iceland.

Physical geography and geology is an enormous and fascinating subject, and this film only touches upon the surface of the discipline. For those who wish to further advance their knowledge in this field, additional reading and research is recommended.

The film was created as part of The Weight of Mountains filmmaker residency program. For more information please visit twom.is/

Penelope Umbrico
[Maybe best known for Suns (From Sunsets) from Flickr, 2006-ongoing http://www.penelopeumbrico.net/Suns/Suns_Index.html

"This is a project I started when I found 541,795 pictures of sunsets searching the word “sunset” on the image hosting website, Flickr. I cropped just the suns from these pictures and uploaded them to Kodak, making 4" x 6" machine prints from them.

For each installation, the title reflects the number of hits I got searching "sunset" on Flickr on the day I made/print the piece – for example, the title of the piece for the Gallery of Modern Art, Australia, was 2,303,057 Suns From Flickr (Partial) 9/25/07 and for the New York Photo Festival it was 3,221,717 Suns From Flickr (Partial) 3/31/08 - the title itself becoming a comment on the ever increasing use of web-based photo communities, and a reflection of the ubiquity of pre-scripted collective content there. I think it's peculiar that the sun, the quintessential life giver, constant in our lives, symbol of enlightenment, spirituality, eternity, all things unreachable and ephemeral, omnipotent provider of warmth, optimism and vitamin D, and so universally photographed, finds expression on the internet, the most virtual of spaces equally infinite but within a closed electrical circuit. Looking into this cool electronic space one finds a virtual window onto the natural world.

Dung Beetles, Dancing to the Milky Way : The New Yorker
"The cosmos is nothing if not egalitarian; we are all equally small. It seems fair that Earth’s sanitation workers should benefit from the Milky Way, as the rest of us do. And dung beetles likely aren’t alone; crickets, moths, nocturnal bees, and other insects probably share their ability to navigate by the Milky Way and by polarized moonlight. “I’d be surprised if they were the only insect,” Warrant said."

"We suppose that we are superior to dung beetles, but are we really? At least dung beetles recycle. We scavenge, hoard, consume…what? Crap, mostly. It piles up around us; increasingly we live on a ball of it. Even light we waste; designed to illuminate, it now obscures. As our celestial guides recede, we risk losing our bearings and will have ever less to consider but ourselves."

Let's assume that I am the stupidest person that ever lived. Explain to me what JavaScript is, what it does, and how a moron would go about learning it... - web design coding | Ask MetaFilter
"So Netscape said to a guy named Brendan, who worked at Netscape, "Please make us a programming language. Also, you have to call it Javascript.<br />

The "look like Java" mandate came early, but the name was "Mocha" from May 1995 until around September, IIRC, where it became "LiveScript" (to match Netscape's "LiveWire" server authoring CMS PHP-like offering with browser-based HTML editor).

The data is streamed to Earth by NASA’s twin STEREO spacecraft which monitor the sun from two different spots, one ahead of Earth in its orbit and one behind, giving stereoscopic images to give a sort of three-dimensional view, similar to the way our two eyes do."
