The city of Los Angeles recently finished replacing all of its streetlights with high-efficiency LED lights. They use less power, last longer, and require less maintenance than even the sodium vapor lights — an all-around win. They also cast a slightly bluish light, eliminating the amber look of sodium. But my first thought was that with all that work, they could have taken the opportunity to combat light pollution. The night sky doesn’t seem any darker than it did when we moved up to this area.

Then I took a good look at these LED street lights near work. The new fixtures actually do aim all the light downward, shielding upward leakage. They’re plenty bright from the ground, but from a few stories up, I couldn’t tell which lights were on without looking below them to see whether there was a pool of light on the ground.

So if the streetlights really are leaking less light into the sky, why is it still so hard to see stars to the north? Seriously, I can see Orion clearly most nights, but the Big Dipper is practically impossible to pick out.

  • It was a city project, not a county one. There are plenty of other cities in the area that either haven’t been converting their lights, or have only converted a few.
  • They didn’t actually convert all the streetlights in town, just the standard, boring ones (141,089 of them). Phase 2 is converting decorative street lights.
  • There are lots of other lamps that leak light upward: Parking lots, building lights, private roads. LAX is to the north, and there’s a reason for the phrase “lit up light a landing strip.” There’s also a park nearby with a baseball field; those lights drown out quite a bit when they’re on.
  • The ongoing drought has caused smog levels to climb, making the skies hazier.

Rain lit up by a car headlight.Speaking of the drought, I found myself wondering: How much water would we save if the city did a similar project to replace all the grass along street medians, parking lot boundaries, etc. with drought tolerant native plants? A home lawn at least has a potential use as a gathering place, or a play area. But a little strip of lawn six feet across? What’s the point?

And what do they do with medians out in the high desert, anyway? I remember driving out to Joshua Tree once and noticing in one of the towns along the way that all the houses were built on a standard suburban lot plan with space for a lawn, but that they used it for rock gardens, or native plants, or just left it empty. But I can’t remember what they put along the sides and middles of city streets.

And that gets me to the other article: It was a summary of a study on the vulnerability to climate change in various parts of the region. Most of LA will handle a rise in sea level fine, except for the beaches, Marina del Rey, and San Pedro…but depending on how the climate changes, most of LA would be vulnerable to severe flooding.

In any given decade in California, you can expect at least one drought and at least one winter of heavy rains and flooding. And sometimes those floods can be spectacular. A flash flood in 1825 changed the course of the Los Angeles River (it used to flow into what’s now Marina del Rey). And then there’s the Great Flood of 1862, which covered huge swathes of California and Oregon with water, including all the lowlands of what are now Los Angeles and and Orange County.

So in addition to planning for drought, the region also plans for the occasional flood — unfortunately, by trying to channel all that water out of the way as quickly as possible, because, as the study pointed out, more than 80% of the ground in the area is covered with impermeable surfaces — you know, asphalt, concrete, buildings, etc.

They do have spreading ponds to replenish groundwater from at least part of the storm drain system, but a lot of that water just goes straight into the ocean, and in heavy rains, the ponds get overwhelmed anyway.

It just seems like there ought to be a better way to capture the rain we do get.

I’ve been using Pocket lately to offload “Hey, this looks interesting” articles from times when I really should be doing something else to times when I have, well, time.

  • It syncs a copy of the article to each mobile device, which means I can see something in the morning, save it to Pocket, then read it on my tablet at lunch.
  • Feedly talks to it easily. I’ve even linked it up with IFTTT so that tapping “Save for Later” on the tablet will add an article to Pocket.
  • Speaking of IFTTT, I’ve also set it up so that saving an article as a favorite in Pocket also adds it to Delicious.
  • The Android app will accept shares even if there’s no network connection, then sync up when it’s online. That means I can look over a newsletter in Gmail at lunch, save the links that look interesting, and archive the email. Then I can read the article at work or at home…or the next time I’m out somewhere, after it’s synced.

I’ve also started using the text-to-speech feature to listen to articles in the car while driving to and from work. The voice is fairly decent despite the usual flat tones and lack of natural rhythms, but there are a few oddities that take getting used to.

  • # is always read as “hash.” This makes it really odd for comics articles, which frequently talk about issue numbers. “Batman Hash 123” just sounds wrong.
  • Italics are…always…emphasis, and presented by…pausing…rather than changing tone. This makes it…awkward…for anything involving lots of titles.
  • It parses words, rather than using a dictionary, and can’t always figure out whether initials should be read individually or pronounced as a word. This usually works fine, but occasionally leads to phrases like “tah-kay-down notice,” (takedown) “link-uh-din” (who knew LinkedIn rhymed with Vicodin?) or “pohs terminal” (POS as in Point-Of-Sale) On the other hand, it figured out “I-triple-E,” so I imagine it’s got a dictionary for special cases.

Last night I had to do some late-night laundry, and when I went in to move clothes from the washer to the dryer, I noticed water on the floor. My first thought: Great, the washing machine’s busted. On opening it, though, it looked like it had at least drained fine. So I checked the closet for the water heater.

Bingo: A fine jet of water spraying out the side of one of the pipes.

So I got out some duct tape, figuring it could block the leak for a few hours, and notified the landlord so he could call a plumber.

It was dripping again by the time I finished writing the text. Maybe it would have worked if I’d been able to shut off the water to that pipe before putting the tape on, but my plumbing expertise is…rather limited. I didn’t want to mess things up any more than I had to.

But I did know that you don’t want water puddling on your floor, even if it’s a concrete laundry room floor, so I put a container down to catch the drips (now that it was only drips). It was full by the time I came back for the clothes.

Then I noticed the wall vent near the damaged pipe. There was a small hole in the screen to allow an overflow pipe to run outside, and it was a few inches below the bottom of the pipe that the hot water was trickling down.

Lightbulb moment: Cut a Pringles can in half and make a trough to channel the water out through the vent and into the planter outside.

Problem: I don’t think I’ve bought a can of Pringles in over a decade.

Solution: A paper towel roll lined with foil.

I actually ended up using several toilet paper rolls taped together end to end, but it worked: The spit-and-baling-wire contraption diverted the water outside, keeping it from flooding any worse until the plumber arrived.

Yeah, it’s best to fix something right. But sometimes you need to patch it now and fix it right later.

Trickling Out

San Francisco Food Court Trash Cans

In the old days, trash was trash and as long as it wasn’t cluttering the place up, you didn’t worry so much about where it was going. These days we’re more aware. In the LA/OC area, you can often get residential recycling (and sometimes green waste for compost) along with your trash pickup, and malls and other areas often have bins for aluminum cans and glass/plastic bottles.

San Francisco goes a step further, with not just trash and cans/bottles, but trash, recycling (all), and compost. More importantly, they’re labeling the “plain” trash as landfill. It makes you think about where the trash is going, and a bit more likely to separate it so that things are a bit less messy and wasteful in the long run.

But for the short term, it really takes a while to figure out which bin to put your trash in.

Stranded travelers leaving LAX on foot down a closed Century Blvd.

I work in an office building across the street from Los Angeles’ main airport, LAX. This morning was….interesting.

I was driving to work as usual, and noticed two things:

  1. Just past the next intersection, the street was completely full of stopped cars.
  2. At least five helicopters were hovering in place up ahead.

This is the third time in as many months that I’ve seen helicopters just holding position like that near the airport. Once the choppers were keeping an eye on a damaged airplane making an emergency landing. Once was the ex-TSA agent bomb scare on September 11.

I turned onto a side street and took a back way to the parking structure. The drone of helicopters was stronger when I got out of the car, and police car after police car started racing down the left side of the street, sirens blaring.

The building concierge hadn’t heard what was going on. She just shrugged and said, “L.A.”

Once I got into the office I found out what was going on: There had been a shooting at the airport, an incident still ongoing. There were still airplanes taking off at the time, though we hadn’t noticed anyone landing, and more and more helicopters took up position in the sky down the street.

Information was still spotty at the time, so I sat down to work, but it’s unnerving to listen to the constant drone of helicopters when you know they’re there because something’s wrong, especially when that sound is punctuated every few minutes by yet another siren.

By lunchtime, Century Blvd. had been blocked off by police and the trapped cars had been cleared out, leaving the street eerily empty. A stream of stranded travelers trudged along the sidewalk and in lanes, dragging their luggage away from the airport and toward hotels, offsite parking, or transportation. The cafe downstairs was swamped (though not as full as I’ve seen it during conventions).

What surprised me were the people getting out of cars at the curb just outside of the barricaded area, pulling their suitcases with them and starting the mile-long trek toward the airport. I can only assume they were counting on delays being lifted by the end of the day and their flights actually taking off. Though I’m not sure what the people waiting at the bus stop inside the closed area were planning to do.

It’s about two in the afternoon right now. I’m pretty sure I heard an airplane take off a few minutes ago. Most of the helicopters are gone, and while the street still looks closed, I can see more people walking toward the airport than away from it. It looks like things may be starting to return to normal.

Update 6:00pm: Century Blvd has been re-opened for traffic (though I wouldn’t say it’s moving, and airplanes are taking off again. If you look closely in the picture below, though, you can just see some helicopters still holding position above the airport.

Backed up traffic at sunset

On a completely different note: I’ve decided to try NaBloPoMo and post every day this month. I’ve been getting all the NaNoWriMo emails, and while I don’t have the time or story ideas (and Katie’s covering the “writing a novel” thing), I’m a little nostalgic for a writing challenge.

Wow. A study finds that only 54% of patients experiencing an anaphylactic episode requiring an ER visit or hospitalization get an epinephrine prescription within a year, and only 22% visit an allergist or immunologist in that time. (via this week’s FARE newsletter)

The article treats this as an education/compliance issue, but I have two big questions:

  1. How many of these patients discussed the incident with their regular doctor? It’s possible that more than 22% followed up with a doctor, just not with a specialist.
  2. How does insurance coverage correlate? If you don’t have insurance, it’s expensive to see a specialist, and expensive to get an Epi-pen (though there are generics now that are a bit cheaper)…especially after you’ve just received a bill for thousands of dollars for the emergency room.

Regarding #2, the study looked at “healthcare claims,” so if I’m reading that correctly, they may have only looked at people who do have insurance. If that’s the case, I wonder if it would be possible to break it down by type of insurance: HMO vs. PPO, do they charge a higher co-pay for specialists, etc. Our current system could do a lot more to encourage preventative care.

For the record: The first thing I did when I got home from that San Diego trip was to order a replacement Epi-Pen, and Monday morning, I called up my allergist to schedule an appointment. But then, I already had an allergist, a prescription, and insurance.
