Terry Lake 2009

For many years I've been spending Easters, Thanksgivings and Christmases with Wendy's family in Terry Lake, Fort Collins, CO. The lake's north shore is hugely photogenic, so nice photos are easy pickings each year.

This Christmas was no exception. I zipped out at sunset one evening and shot this set:

Broncos v Raiders

While in Denver over the holidays Wendy and I went to the Broncos/Raiders game at Mile High Stadium (or "Invesco Field at Mile High"). We'd managed to get fantastic tickets for seats on the 4th row at the 40-yard line, Broncos side, and the weather turned out to be absolutely beautiful.

Tragically, and heart-breakingly, the Broncos lost to their arch-rivals in the last minute of the game—chances of reaching the playoffs diminishing accordingly. Still, I got some good photos.

Christmas Gifts

This year I was lucky enough to receive the most kick-ass selection of books. I can't wait to get started working my way through the pile:

I also received one of the most fantastic Christmas gifts ever: a Korg Kaossilator. Holy moly this thing is some kind of super-addictive-awesome.

Also: a Brookes saddle for the fixie and a two-tone chopping board. Got to love it.

Day Labor

One of my recent favorites is this one.

Intersection

It was taken at the same intersection as this one:

Day Labor

Round here we have very enterprising day labor crews. Within three blocks of our house you could recruit an army for contingent work, should you ever need to.

Fall In Bernal

Bernal Hill is a few blocks south of where we live in the Mission. I find the area incredibly photogenic.

Yesterday Wendy and I went on a walk up and around the hill, as we often do. In the fall afternoon sun I got a set I'm fond of, some of which are below:

Limited Unlimited

[an atypical business-related post with due credit to the Telco 2.0 Blog, an excellent resource on the modern economics of telco]

I've witnessed this point argued again and again: at my current employer, my previous employer, and the one before that. Telcos are greedy; telcos sell "unlimited data" but deliver otherwise; telcos will lose the broadband market to a player who can offer better value; and so on. Definitely I'm not defending misleading marketing of broadband services, but claiming that telcos are on a mission to exploit consumers falls short of the mark.

It's really not as simple as that.

The problem the telcos have is this: their costs building and running a packet-switched network are fundamentally a function of data volume on that network, (# of bits transported) * (cost per bit). As a first-order approximation, this linear function works pretty well; in this simplified model the cost per bit is an aggregation of OpEx and CapEx (amortized). CapEx includes licensing wireless spectrum, building out towers and backhaul and so on.

Telco costs are a function of data transport volume, more or less.

So you might be tempted to think that a "cost-plus" pricing model is the answer: charge the consumer per transported bit (ie. a metered data plan) at a rate of X * (cost per bit), where X>1. In general these pricing plans don't work well because on the consumption end what users end up paying doesn't correlate with the value they're getting. Is watching that YouTube video on my iPhone 100x more valuable to me than downloading that email from my boss? No, but it might cost me 100x more. Consumers can't make sense of that, and metered data plans haven't worked for the industry.

Consumer value is not a function of data transport volume.

So the telcos move to a subscription-based pricing model, otherwise known as flat-rate. Here they charge you a monthly fee for access to the network but typically give you "unlimited data" along with that. This is easy for consumers to understand, avoids the problem of data value being independent of data volume, and everything works just fine... EXCEPT that now the telco's revenue is a function of (# of subscribers) while their costs are a function of (# of bits transported).

In a subscription-based world, telco data costs and revenues are decoupled.

Having your revenues decoupled from your costs is a dangerous situation to be in, because you could easily find yourself paying out more money than you're taking in. So you try a few things:

  • you place a cap on the "unlimited data", to control how far revenues can deviate from costs and keep your margins positive. Providers are in general moving this way.
  • you start throttling traffic, for the same reason
  • you start looking at ad-supported models, inserting X ads per bit transported, to couple revenues to costs again
  • you start looking for a way to make your costs independent of traffic but instead a function of the number of "unlimited data" subscribers

After the launch of iPlayer in the UK (iPlayer is the BBC's streaming media product), one major ISP revealed that their costs of carrying streaming traffic trebled within weeks. Unless they can pass those costs to consumers, or fund them some other way, or prevent them entirely, they'd be in trouble. Bad news when your costs treble and your revenues don't.

Thanksgiving

Thanksgiving is an interesting time if you're an expat in the States. Intellectually of course I "get" the protocol—the family gatherings, the turkey meal, all-day Bond marathons on TV, mega-retail, putting up the Christmas tree, and so on—but viscerally my experience seems inevitably different from that of those around me. They've grown up with the holiday and I haven't.

The difference isn't about knowing the rituals: these can easily be learned and acted out. The difference is that after decades of experiencing the tradition it internalizes and becomes a "feeling". Thanksgiving has a particular "feel" to US natives, the substance of which is an aggregation of memories going all the way back to childhood. Thanksgiving doesn't have a "feel" for me in a way that Christmas Eve does, for example.

This isn't to say, of course, that it's not a good time. This year Wendy and I stayed in San Francisco for Thanksgiving, something we've not done before. We were thankful for each other, the amazing city we live in, the Californian climate, the house we love to live in, and the beauty of the fall.

Kidney Stone

If you search Wikipedia for "worst pain ever experienced" the #1 result is "kidney stone". Until a couple of weeks ago I didn't really know what kidney stones were and the worst pain I'd ever experienced was appendicitis nearly six years back.

All that changed, though:

  • Sat; arrive back from England
  • Sun evening; go to bed just fine
  • Mon 7am; go to work as usual
  • Mon 1pm; do three back-to-back phone interviews with Google job candidates
  • Mon 6pm; go home
  • Mon 9pm; go to bed, still jetlagged from England
  • Mon 9.05pm; sudden severe pain in left side of abdomen
  • Mon 9.10pm; out of bed, agony
  • Mon 9.15pm; writhing on floor. Wendy calls an ambulance
  • Mon 9.25pm; completely incapacitated, speechless with pain
  • Mon 9.30pm; paramedics arrive and deliver oxygen, IV and ECG
  • Mon 9.50pm; arrive at the hospital, given intravenous narcotics
  • Mon 10.40pm; drugged out out of my mind, receive a CT scan
  • Mon 11.15pm; diagnosis from physicians in Australia, working in-timezone (seriously!): kidney stone in right kidney
  • Tue 12.15am; arrive home and go to bed
  • Tue 8am; painkillers
  • Tue 10am; painkillers
  • Tue 12pm; painkillers and sleep
  • Tue 4pm; write up interview feedback
  • Tue 9pm; painkillers and more sleep
  • Wed 7am; back to work, not very comfortable, painkillers
  • Wed 1pm; three more back-to-back phone interviews
  • Wed 8.30pm; "egress" of a kidney stone the size of half a grain of rice
  • Wed 8.31pm; feeling fine, pain-free
  • Wed 9pm; write up interview feedback

The strangest thing.

Last week in England

Isaac's advice for this week: avoid kidney stones. Badness.

About last week: I spent it in England, including visiting my parents a couple of weekends ago. On the Saturday we had a lovely day with a break in the clouds and went for a walk around the village:

Ellis Island

As an immigrant myself, it was touching and poignant to visit Ellis Island and I'm glad that I did. What a place!

I was captivated by the reception hall on the second floor. This is what it looked like 100 years ago:

Central Park

The walk from SoHo to Wall Street was part of a longer walk from SoHo to Battery Park, with the intention of hopping on a ferry to Ellis Island. At 3.30pm or so, though, the line for ferry tickets was about 45 minutes with an additional 60 to board a boat after that. We figured we'd skip it and come back first thing the next day.

Instead we dropped in on the hotel, picked up our books and headed to Central Park. While we hung out I got some great shots in the late afternoon autumn sunshine, like this one:

Empire State of Mind

Sunday in New York I woke up early and started my research on the Empire State Building. Did you know it was built in just 410 days? Or that in 1945 a B-52 bomber crashed into it and precipitated the longest survived elevator fall recorded (75 floors). Or that because it opened during the Great Depression they had such problems finding tenants that in the first year they took in more money from tickets to the observation deck than from commercial rent?

I also learned, crucially as it turned out, that you can buy Express Tickets online. From the site:

The lines at the Empire State Building Observatory are as legendary as the building itself. The line actually consists of 3 different lines. The first one is the security line that everyone must go through. Next comes the ticket line. Visitors with pre-purchased tickets can skip this line which can save a considerable amount of time during our busiest times. The 3rd and last line is for the elevators that take you to the Observatory.

While we have been told that anything this good is worth the wait, we have also heard laments that some people missed out on being able to visit the Empire State Building Observatory because they just didn’t have enough time to see and do everything while in NYC. Now you can. By purchasing an Express Pass you will automatically be moved to the front of each and every line.
and it's true. There are lines to get in, to get authorized, to get screened, to get up, to get down, and to get through. Pay the little extra for express tickets and it's like these lines don't exist. Empire State visitor pro-tip. Save two hours.

It was a wonderful clear day and I took a bunch of photos. You can find a selection in the usual spot on Flickr. An example:

NY in B&W

I went to New York for the weekend to meet my mom, who was also there for the weekend. She rightly had the list which every NY first-timer develops before their trip, and the first day there found us in Grand Central Station.

Completely fabulous place! We checked out the Campbell Apartment but it was too busy so we ended up drinking in Cirpriani's. The whole experience was utterly photogenic:

About Truisms

A couple of people asked after my last post, Truisms.

I was watching the movie Helvetica (a great movie, by the way). About 50 minutes in begins a segment with this guy Stefan Sagmeister, who says

I myself got fairly disappointed with modernism in general. It simply became boring. If I see a brochure now with lots of whitespace, that has six lines of Helvetica up on the top, and a little abstract logo on the bottom, and a picture of a businessman walking somewhere—the overall communcation says to me "do not read me because I will bore the shit out of you"

Stefan himself was not the most engaging individual ever, but behind him was a poster series of Jenny Holzer's Truisms. See here in a frame from the film:

About Propofol

Very few of my childhood friends am I still in touch with. Fewer still do I have any meaningful relationship with, but one of those with whom I do happens to be both a smashing stand up guy and a super-successful real-life medical doctor.

This friend of mine works in anesthetics (anaesthetics in the UK), so I figured I'd ask him about the Michael Jackson case. What's the deal with Propofol? Pretty illuminating what he said:

Yes. I use it a lot. Almost every day when I'm doing anaesthetics. It's my bread and butter, my pharmacological hammer of choice, my 'go-to' anaesthetic.

Basically it's most commonly used as an Induction agent, ie. it'll put your patient to sleep (AND STOP HIM BREATHING—crucial detail—remember for the test later) in 10 seconds, but in the next five minutes you'll need something else or he'll be getting a little frisky. The 'something else' can either be a vapour added to your oxygen line (the commonest and cheapest way of keeping someone asleep) or if you prefer, more Propofol. If it's going to be used to keep you asleep it'll be delivered by an electronically controlled pump which is designed to keep the concentration of the drug in the brain at a certain level.

Now. I didn't know it was a drug of abuse. For the following reasons:

  • it'll kill you in the wrong hands.
Oh yeah. See? I was right.

So it shouldn't be used by anyone who's not an anaesthetist. This whole 'toxic level' stuff is bollocks. It was doing what it's supposed to do. When it's given in hospitals, the patient stops breathing, and would die if the anaesthetist weren't there, but that's the point. That's what it does, and that's why we're there.

I can imagine that they were trying to use it at very low doses (at which concentration it's more of a sedative than an anaesthetic) but that's really playing with fire, because individual responses are difficult to predict and it's easy to get it wrong if you're not experienced. Every anaesthetist has given a little too much or too little when we were less experienced—but it's forgiving in the right environment, ie. with all our tubes and machines that go 'beep'. Without them? Disaster is inevitable.

The short verson: anyone giving, administering or supplying MJ with Propofol should fry. There's no medical use for it outside a critical care medical environment.

I love it that I know such smart people.

Painting with light

Lots of people have been asking how the light painting photos were done. There's been speculation about multiple exposures, unseen spotlights, dark cloth, and even Photoshop (I don't use Photoshop). It's actually much much simpler than that.

  • Step 1: find somewhere really dark and put the camera on a tripod. For all of these shots the dark place in question is Costanoa at night. It's a camp site on the northern California coast, about halfway between Santa Cruz and Half Moon Bay.
  • Step 2: open the camera's shutter for a minute. For the technically inclined, almost all the pictures were done with an exposure time of 60 seconds at aperture f6.3, ISO 400 sensitivity. Pretty much any SLR, and now many compact cameras, could be configured with these settings; there's nothing special about the camera.
  • Step 3: step into the frame with a flashlight and "paint" your chosen design. This is where it helps to have someone as artistically inclined as Matt; in pretty much all of the good pictures it was actually Matt stepping into the frame and wielding the torch. I did one or two, but it's Matt's creative genius behind the really spectacular examples.

The painting itself can take a few forms:

  • mid-air painting; just sketching shapes in mid-air. The dinosaur is a great example of a standalone line drawing.
  • painting still objects; shine the flashlight on still objects in the background, or on the ground. For the forest path picture, Matt pointed the flashlight at the ground and walked off into the distance, lighting his path in front of him as he went.
  • painting people; pretty much anything you want to actually see in the photo you have to paint with the flashlight, and that includes anyone standing in the frame. They must hold very still while you paint them but it can be done in a second or less.

Here's a video showing the process in action. There's not a whole lot to see but it gives you a good idea of how it's all done.

Yes, it's pretty dark! Matt begins by painting the wings, then paints the ground around our subject April (it's this which gave some the impression of a spotlight from above). At 36 seconds in, one wipe of the flashlight over April is enough to paint her into the photo. After that Matt picks up a blue glowstick and paints an aura. The finished result:
IMG_8071

There are lots more of the pictures on Flickr. Diabolical Alexia is one of my favorites; Horse is another.

Here are some of the questions I got asked a lot:

How come the painter isn't visible in the photo?
Mainly because as the painter you're careful not to shine light on yourself. You also have to keep moving as you paint; if you stay in one place for too long then ambient light will indeed put you in the photo as a ghostly blur.
How did you get some of the drawings looking so good?
Matt is excellent at drawing. That's all there is to it.
What's special about the flashlight?
Nothing. It's a regular Maglite (three D-cells). We've also used a mini Maglite (2 AA-cells) and colored glowsticks for different effects.
Got any tips for light painters?
Yes, we learned as we went:
  • keep moving. If you stop for too long the ambient light will illuminate you and put you in the picture;
  • don't accidentally shine the light on yourself. A few promising pictures were spoiled from leaked light;
  • light human subjects quickly, and only once. Most people can't keep perfectly still enough to make any other approach practical;
  • turn off lights not in use. Covering a flashlight with your hand while you move will leave a red trail in the picture. If you're carrying glowsticks, keep them deeply buried in a pocket;
  • when drawing shapes, point the flashlight at the camera even when reaching up or down. It's natural when painting something above head-level to point the flashlight up into the air. If you do that much of the line will be lost;
  • the speed at which you move the flashlight will determine how much light gets painted. Move it quickly for less light and slowly to create very bright patches.
  • manually focus the camera on your subject. Leave that focus setting and put a marker in the ground so subsequent subjects can stand at the marker to be in focus

Enjoy!

Costanoa

We interrupt your regular broken wrist programming to bring you news of my weekend in Costanoa. Wendy and I went down there with Matt and Mary on Friday night and stayed for a couple of days; kind of a reconnaissance mission for an upcoming departmental offsite and kind of just a weekend getaway with old friends.

On the web site it says

Costanoa is an eco adventure resort designed to encourage our guests to explore the stunning beauty of our protected California coastline and Discover the Pace of Nature
to which I say
Costanoa is an unusual campsite in a lovely part of California—by the sea, and in a relatively remote area of the peninsula

What makes it an unusual campsite? Mainly that it has pre-built super-comfortable tents for the lazy. Again from the web site:

Bungalows are a wood or metal frame with waterproof canvas tent walls. They have electricity, sliding windows, a locking door and heated mattress pads. These accommodations combine the best part of camping with creature comforts you will appreciate.
So they're more huts than tents. And perfectly nice huts at that, with beds and nightstands and an electric blanket and bedside lights. They have comfy wooden chairs outside, for hanging out in the sunset, and each has a lockable door. No suburbanite camping concerns of theft et cetera:
Remote Hut
Costanoa

Somehow I had visions of actual real fancy upscale camping, though, and on that front Costanoa was a bit of a disappointment (especially considering the rate of $130/night). One has to imagine that there is indeed a market for luxury camping, where the pre-built tents have housekeeping and turndown service daily, a concierge, room service and a white-gloved bellboy to light your camp fire.

But it's not like that at Costanoa. It's just camping in a hut with a bed. Insects: yes. Cold: yes. Dial 7 for reception: no. "Skeevy" (to use Wendy's word): perhaps a little. Bathroom a fair walk away: yes. Skunk hanging out under the hut: yes. Towel service: no. Chocolate on the pillow: no. Communal showers: yes. Complimentary long-stemmed roses and champagne on ice: no. And no cell service, no power outlets; Wi-Fi doesn't reach the huts. You make your own fun, as they say, and boy did we ever:

Forest Path
Cut Here
Angelic Wendy
Flower Arrangement
Racing Car
And so forth and so on.

A wonderful area of California, though. Even after four years here I'd never been on Highway 1 between Half Moon Bay and Santa Cruz, but it's a lovely scenic stretch of road strewn with farms and beaches and super views. On Saturday we all went down to Capitola; Matt, Mary and Wendy took surfing lessons while I hung out with—ahem—a broken wrist.

Brunch in Santa Cruz on Sunday: also nice.
