San Francisco-Oakland Bridge: LEDs, Cool Photo


(Teton Gravity Research, via Wired, used w/o permission)

"Check Out the San Francisco Bay Lights in 4K Glory"
Christina Bonnington, Gadget Lab, Wired (April 1, 2013)

"The Golden Gate Bridge has long overshadowed its grayer, plainer companion, the San Francisco-Oakland Bay Bridge. That's changed, just a bit, now that the Bay Lights illuminate 'the other bridge' with the glow of 25,000 glittering LEDs.

"We've been lucky enough to see them each night since they first lit up March 5, and now you can enjoy them too - in stunning 4K definition.

"The video was shot with a RED Epic attached to Gyro-Stabilized Systems' C520, a portable five-axis gyro-stabilized camera platform. It's the first such system that is fully upgradable, interchangeable, and can accommodate 4K camera tech...."

It's a pretty cool photo. The copy in this post was cropped to fit the Lemming's format.

What's really impressive is what it took to get the video: for that you'll have to read the Wired article.

Normally, the Lemming would ramble on about LEDs, San Francisco, or maybe bridges. It's been one of those weeks, though, and the Lemming's taking a break.

Save the - Goldfish?!

"San Francisco Wants to Ban Goldfish to Prevent Their 'Inhumane Suffering' "
Todd Starnes, FoxNews.com (June 16, 2011)

"The San Francisco Animal Control and Welfare Commission wants to take away your goldfish, proposing a bill that would also include a renewed ban on pets like puppies, kittens and hamsters.

"The proposed ban is meant to discourage 'impulse buys' of pets that sometimes end up at shelters, said commission member Philip Gerrie....

Before anybody has a stroke, please note that the Lemming thinks:
  • Animals should not be mistreated
  • Pet owners have responsibilities
  • Kittens and puppies grow into cats and dogs
  • Free Willy was a fun movie
The Lemming also thinks that even elected officials should think before acting.

Is impulsively buying a kitten or puppy - or a baby chick - a bad thing to do? Not, in the Lemming's opinion, necessarily. In principle, it's possible for someone who knows about litter boxes and leash laws to suddenly decide that it'd be nice to have a kitten around - and a dozen years later still be taking care of the long-since-grown-up cat.

The Lemming also realizes that not everybody who grabs a cute little ball of fur and fangs really understands what having a pet means.

That's the real world, now, back to the article:

Swim Free, as Free as the Wind Blows - - -

"...He [commission member Philip Gerrie] said goldfish, guppies and other tropical fish were added to the proposed ban because of what he called the 'inhumane suffering of fish' and the way the fish are harvested.

" 'It causes animal suffering,' Gerrie told Fox News Radio. 'Whole reefs and ecosystems are being exploited for whatever might be marketable or sellable.'

"The Board of Supervisors considered a similar ban last year that would have included dogs, cats, hamsters, mice, rats and guinea pigs – but not fish. That proposed ban was tabled last August. The supervisor said they were going to reconsider it in January of this year – but did not.

"The proposed fish ban has local pet store owners up in arms...."

There's a lot going on in those four paragraphs.

Fish Really do Have Feelings - Sort of

About the "inhumane suffering of fish?" That may not be as crazy as it sounds. Fish are animals with a central nervous system that doesn't work all that differently from ours.1

On the other hand, it's anyone's guess whether or not the San Francisco Board of Supervisors is aware that domestic goldfish are just that - domestic. There are no prides of Lionhead Goldfish swimming free along the sunlit shores of some exotic island.

Commercial exploitation of exotic animals, that's something else.

Remember how groovy "zero tolerance" must have seemed at the time? And that isn't quite another topic.

By the way, here's an entirely different sort of commercial goldfish:

Save the Endangered - - - Rats?!

Last year's efforts to save San Francisco's (pet) rats may not have been the result of someone assuming that greedy pet store owners recklessly disturbed delicate ecosystems in the city's dumpsters and sewer system, harvesting rats for the pet trade. Still, you never know.

Again - rats have central nervous systems. They're not all that different from mice - and the Lemming's been over this before:In the Lemming's considered opinion: elected officials should get out of the office more often, and see what it's like on the planet the rest of us call home. So, again in the Lemming's opinion, should quite a few scientists.

And that is another topic.

San Bruno Fire: Enter Investigators - and Lawyers

"Gas explosion, San Bruno: how authorities will investigate it"
Christian Science Monitor (September 10, 2010)

"The massive explosion Thursday evening in San Bruno, Calif., which killed at least four people and leveled 38 homes, was apparently sparked by a ruptured natural-gas line. Now, as authorities and residents deal with the aftermath of the gas explosion in San Bruno, attention is turning to the regulators and the regulations that govern the massive skein of pipelines moving natural gas in the United States.

"The national regulatory program to assure the safe transportation of natural gas, petroleum, and other hazardous materials is administered by the Department of Transportation - specifically, the Pipeline and Hazardous Material Safety Administration, acting through the Office of Pipeline Safety.

"These regulators oversee more than 2 million miles of pipelines throughout the United States, which provide 25 percent of the nation’s energy, according to the American Gas Association (AGA). More than 650,000 miles of pipeline were added between 1984 and 2004...."

Despite the article's title, there isn't all that much detail on how the San Bruno explosion and fire will be investigated. Naturally enough, for an article that's probably intended as a quick introduction for a non-technical audience. Here's a sample:

"...A key part of the investigation will be finding the precise point of the explosion. Additional things to look into, say 'fire and explosion' Michigan attorney Mr. Stuart Sklar and others, include: Has the pipe failed before? Was the explosion a result of faulty pipe fittings, corrosion, or nearby excavation?..."

Aside from providing gainful employment for lawyers, investigating this sort of accident is important - so that the odds of similar events happening can be lowered.

The Lemming suspects that there will be a bit of hand-wringing about dangerous technology in general and fuel like natural gas in particular. The stuff's dangerous, no question about that. But even back in the 'good old days' it was possible to hurt yourself by falling into the cooking fire - or cutting yourself while knapping a new spearhead.

On a more positive note, there's this paragraph, at the end of the article:

"...According to the AGA, reported explosions have declined 28 percent from 1986 to 2004. Natural gas causes an average of about 2,000 home fires a year, according to the National Fire Protection Association."

One of the down sides to natural gas as a fuel is that it's a gas - and isn't necessarily visible if it's leaking into a room. And then there's the occasional fellow who'll go looking for a gas leak with a lighted match.

Natural Gas Line, Explosion, Fire, and a Really Bad Night Near San Francisco


Update (9:45 a.m. CDT, September 10, 2010)

Blood Donors Needed

"Blood center calls for more donations"
The Daily Journal, San Mateo (September 10, 2010)

"Blood Centers of the Pacific is issuing an emergency appeal for blood donations, particularly of Type O negative, to replenish the supply currently being depleted by those injured in Thursday’s explosion and fire in San Bruno.

"Area hospitals are requiring significant amounts of Type O negative blood — the type that can be given to anyone in an emergency.

"While the blood center will be able to move supplies from other hospitals to the ones treating the injured patients...."

This hour's burn victims have enough blood on hand - but the area supply has gotten low as a result of that quick shuffle.

Daylight: Putting Out Hot Spots, Searching for More Victims

"San Bruno explosion and fire kills 4, destroys 53 homes"
San Jose Mercury News (September 10, 2010)

" small army of firefighters continued this morning to fight hot spots in the San Bruno neighborhood devastated by a massive fire sparked by a gas main explosion. At the same the search for possible victims is underway as the death toll reached four and could go higher.

"This morning the San Bruno fire chief said six people had died, according to ABC7-TV, but later the San Mateo County coroner said there were four confirmed dead.

"Meanwhile, two people were arrested for looting in the fire area, according to KTVU-Channel 2.

"The search for victims intensified at daylight as rescue workers combed through rubble across 10 acres of Crestmoor Canyon...."

KTVU has been updating its online article:

Four Dead; 53 Homes Destroyed In San Bruno Fireball"
KTVU (September 10, 2010)

"As of approximately 10:30 p.m. Cal Fire was reporting that the fire was 50% contained and that 10 acres total had burned. San Bruno city officials said at a news conference later Thursday night that fire crews were working to hold the fire, and the city's priority is the safety of those battling the blaze and those affected by the tragedy...."

"...San Bruno Mayor Jim Ruane, who was on hand at the briefing, said that his main concern is making sure the citizens of San Bruno are safe.

" 'I would ask anyone who sees this broadcast tonight to say a special prayer for those people,' Ruane said...."

I posted another excerpt from KTVU coverage earlier today.
One thing seems clear at this point: there's been a really bad fire in a San Francisco suburb, at least one person is dead, over two dozen are injured, and the trouble isn't over yet.

The story's made it into international news:

"Gas blast near San Francisco burns homes, kills one"
Reuters (September 10 2010)

"A natural gas pipeline explosion ripped through a neighborhood in a San Francisco suburb on Thursday, starting fires that burned as many as 25 homes and killing at least one person, local media and officials reported...."

That natural gas pipeline shows up in most news articles: and the odds are that it's involved. What isn't so obvious yet is just why a normally well-behaved piece of technology is incinerating a neighborhood.
"At Least One Dead, Several Others Injured In Massive Bay Area Fire"
2News KTVN Reno (September 10, 2010)

"At least one is dead and several others are injured, some seriously after a massive fire started just south of San Francisco Thursday night.

"The blaze broke out around 6 p.m. in San Bruno, just south of San Francisco and near the San Francisco Airport.

"At first, there were reports of an earthquake, a gas station explosion, even a possible plane crash. In the end, a local fire chief says a natural gas line explosion is to blame...."

I don't think the "possible plane crash" is necessarily out of the running. There's no reasonable doubt, judging from news coverage, that a natural gas pipeline is involved. And that an earthquake isn't involved. A tremor would almost certainly have been picked up by instruments, reported, and incorporated into news coverage by now.

There's no reason to assume that an aircraft ran into the pipeline, rupturing it and setting off the explosion and subsequent fires. On the other hand, there's no reason to assume that's not what happened.

At first the focus seems to have been, quite properly, on evacuating everybody except firefighters - and getting the fires under control. That wouldn't leave much opportunity to look for parts of an aircraft.
Here's the most detailed account I've seen to date:

"Gas-line blast in San Bruno - neighborhood burns"
San Francisco Chronicle (September 10, 2010)

"With a thunderous roar heard for miles, a natural gas line explosion ripped through a San Bruno neighborhood shortly after 6 p.m. Thursday, sending up a geyser of fire, critically burning residents and igniting a blaze that gobbled up more than a dozen houses.

"The wind-whipped blaze jumped from structure to structure in the area near Skyline Boulevard and Sneath Lane, west of Interstate 280, raging unabated for almost an hour as emergency crews rushed in, residents cleared out, and ambulance sirens filled the air.

"The central ball of fire, fed by the gas line, raged past nightfall before abating. By then, about 20 houses and thick stands of trees were engulfed in flames. Power was cut off to the area, and the only light came from emergency vehicles and the smoldering houses...."

Detailed and with some of the more flowery language in coverage of this event. "Geyser of fire ... igniting a blaze that gobbled up ... houses?" Well, that certainly paints a vivid word-picture: although that's awfully close to a mixed metaphor. Never mind.

I sincerely hope that the death toll doesn't go up as the area cools off and people can get in for a detailed search.
More - another detailed report.

"Four Dead; 53 Homes Destroyed In San Bruno Fireball"
KTVU (Posted: 6:21 pm PDT September 9, 2010 | Updated: 11:05 pm PDT September 9, 2010)

"A massive fireball, fueled by a broken natural gas line, erupted in the San Bruno foothills early Thursday evening, destroying at least 53 homes, killing at least one person and sending dozens of people to a local hospitals, six of those in critical condition, authorities said.

"The four-alarm conflagration, soaring several hundred feet into the air in a tornadic column of fire, started at about 6:15 p.m. at Skyline Boulevard and San Bruno Avenue, according to the battalion chief's office.

"As of approximately 10:30 p.m. Cal Fire was reporting that the fire was 50% contained and that 10 acres total had burned. In addition to the 53 homes destroyed by the blaze, 120 homes in the area were damaged.

"The San Mateo County coroner confirmed that at least one person has died in the blaze...."

This detail, from the sixth through tenth paragraphs of the article, is interesting:

"...Local residents said they felt an explosion followed by a fireball that soared hundreds of feet into the air.

" 'We heard what sounded like a plane, then all of a sudden an explosion,' Carmann Robbins told KTVU. 'It shook the window. It kind of startled me. We jumped up and then all you could see was flames. The flames were just spreading all through the houses. I don't think the people had time to get out. It (the fire) was jumping from one house to one house to another.'

"Jane Porcelli, 62, said she lives on a hill above where the fire is centered. She said she thought she heard a plane overhead with a struggling engine.

" 'And then you heard this bang. And everything shook except the floor, so we knew it wasn't an earthquake,' Porcelli said.

"I feel helpless that I can't do anything. I just gotta sit by and watch."..."

"What sounded like a plane" may prove to have nothing to do with the pipeline rupture, explosion, and fires. It's not all that long after the start of this event: and there's going to be a very serious look taken at just what happened.

San Francisco Computer Hijacker Convicted

"S.F. Admin Guilty of Hijacking City Passwords"
Threat Level, Wired (April 27, 2010)

"After a six-month trial, a San Francisco city admin was found guilty Tuesday of a sole felony count of hijacking the city's computer system.

"Terry Childs, 45, was guilty of one count of locking out the city from its FiberWAN network containing city e-mails, payroll, police records, information on jail inmates and more — virtually an all-access pass to City Hall...."

"...Childs' $5 million bail was set five times higher than most murder defendants' because the authorities feared that, if released, he might permanently lock the system and erase records...."

Like Juvenal said, "Quis custodiet ipsos custodes?"

About that high bail? I think it's reasonable, under the circumstances. And, something of a relief. At least one court seems to have caught on that crimes involving computer networks can be very, very serious: and affect a whole lot of people.

More, about San Francisco City Hall cybertrouble:That CNET News article gives a little more detail than some, of what Childs' lawyer claimed was his motive:

"...Childs' attorney had claimed that there was no destructive intent and that Childs was merely protecting the network from incompetent city officials who were trying to force him out of his job."

Sound a little like "the paranoids are after me!" - maybe Childs really thought that only he could defend the network against those officials.

Actually - with a little work - there's a seriously tacky B-movie science-fiction plot lurking here.

Seriously? I hope San Francisco's city government gets someone with good technical skills and a full sack of marbles to give the city's network a thorough going-over. Just in case the former admin left a little surprise in the code.

Bubbles!

Bubbles
Exploratorium

"Sticky Water
  • "The Shape of Bubbles
  • "When Bubble Meets Bubble
  • "Soap
  • "Bubble Colors"


  • There's more, of course. That's just the splash screen/index for the Exploratorium's section on bubbles.

    I've been to the Exploratorium in San Francisco - about three decades back. It was a marvelous place then, and probably still is. The folks who founded it had decided that people learn more if they're able to get involved with processes. Which is a sophisticated way of saying that the Exploratorium encouraged people to wade in and get hands-on with science.

    The organizers were careful, of course. The horseshoe crab had a handler who made sure that the weird critter didn't get hurt, for example.

    The online section of bubbles should be fun to go through - and 'educational' without making you want to scream.

    I checked the page source, and there's quite a lot of text that's supposed to show up on each page. Right now, my browser's not showing any of it, so all I get is a really big white page with pictures like this on it:







    Impressive, of course - but without the accompanying text, somewhat arcane.

    Well, maybe it's just my system. Although everything I've checked today, before and since, displays correctly. I'll reboot the browser, after posting this.
    Update (January 23, 2010)

    Aha! The background graphic hadn't loaded. And whoever designed the page - or the designer's supervisor - had decided to make the pages' font white. And make the default page background white, too. The background graphic is fairly dark, so the white text shows up just fine. If the page background had been a dark color, it wouldn't have made a difference.

    Oh, well.

    San Francisco's Richmond District: Social and Architectural History

    "Social and Architectural History of the Richmond District"
    Christopher VerPlanck, first published in "San Francisco Apartment Magazine" (December 2000)

    "The Richmond District (or Park Presidio as it is officially designated) is located in the northwest quadrant of San Francisco. The district is bounded on three sides by natural features or green space: the Presidio and Lincoln Park to the north, the Pacific Ocean to the west, Golden Gate Park to the south and Arguello Boulevard to the east. This article will concern itself with the core of the historic Richmond, whose boundaries are the same as the Richmond except that the western boundary is Park Presidio Boulevard.

    "The Richmond District is one of San Francisco's largest and most varied neighborhoods...."

    This online article follows the development of San Francisco's Richmond District from dairy farms and open land to a densely populated residential area. With photos.

    You'll want to set aside a bit of time to read this: it's not the terse verbal snapshot that's common on the Web. I think it's worthwhile, though. Although the article is, by online standards, long, the writing isn't fluffy. There's a good idea-to-sentence ratio.

    One paragraph stood out for me, partly because it described an important milestone in the Richmond District's history.
    "...The earthquake and fire of 1906 destroyed most of downtown San Francisco, the South of Market, and parts of the Western Addition and the Mission, driving waves of refugees to open parcels of land at the edge of the city. At first the refugees were housed in small wood-frame 'refugee shacks' hastily erected by the City in public parklands. However, as in other districts that experienced an influx of 'temporary' earthquake refugees (including the Potrero and Mission districts), many people decided to start afresh and settle in the Richmond. Parcels were subdivided within a few months of the disaster and houses began to pop up all over the district...."
    I think events following the 1906 disaster are a sort of microcosm of America's history: people arrive as refugees, and stay as residents.

    Bottom line: this seems to be a pretty good place to learn about the Richmond District's social and architectural history.

    Model Cities Look Great, But I Couldn't Live There

    "Biggest Little Cities: Models for Urban Planning"
    Wired (February 29, 2009)

    "Michael Chesko is no architect. He's not a structural engineer or an urban planner either. But he just spent more than 2,000 hours constructing this highly detailed, nearly perfect scale model of midtown Manhattan. Chesko cut, sanded, and glued the mini metropolis—now on exhibit at the New York Skyscraper Museum—using only an X-Acto knife, a nail file, and a Dremel (and lots of balsa wood). But the 50-year-old software engineer was having fun; he's been building little cities since he was a kid.

    "Model cities aren't just for show; they can have real utility. In 1957...."

    There's a video (3:51), which may or may not load in your lifetime, and fifteen photos of model cities. As the article says, they're not just for show. Some are used for engineering studies. City planning is another use.

    Cool photos, a video that still hasn't loaded, and background on scale models of cities: this is a pretty good resource.

    That video still hasn't loaded: but the little 3/4 circle icon spins around very smoothly.
