The world lacks a great all-around red. Always has. We’ve made do with alternatives that could be toxic or plain gross. The gladiators smeared their faces with mercury-based vermilion. Titian painted with an arsenic-based mineral called realgar. The British army’s red coats were infused with crushed cochineal beetles. For decades, red Lego bricks contained cadmium, a carcinogen.

More than 200 natural and synthetic red pigments exist today, but each has issues with safety, stability, chromaticity, and/or opacity. Red 254, aka Ferrari red, for example, is safe and popular, but it’s also carbon-based, leaving it susceptible to fading in the rain or the heat. “If we sit out in the sun, it’s not good for us,” says Narayan Khandekar, director of Harvard’s Straus Center for Conservation & Technical Studies and curator of the Forbes Pigment Collection. “That’s the same for most organic systems.” One red is stable, nontoxic, and everlasting: iron oxide, or red ocher, the ruddy clay found in Paleolithic cave paintings. “It’s just not bright in the way that people want,” Khandekar says.

I imagine that back at my parents house there are a few buckets of highly toxic old Legos. Who knew red was so difficult?

In the same way that we use an American-style toilet, a Roman user would sit down, take care of business, and watch number two float blissfully away down the sewer system. But instead of reaching for a roll of toilet paper, an ancient Roman would grab a tersorium (or, in my technical terms, a “toilet brush for your butt”).

Since we had busy lives and lived hundreds of miles apart, we agreed on three rules. First, we would play it only in February each year; second, you were not allowed immediately to tag back the person who had tagged you; and finally, you had to declare to the group that you were “it”.

Now we are grown men, we don’t run like Usain Bolt, so subterfuge and collusion have become our weapons. Eleven months of the year are spent planning. Collaborating with a friend is where the fun is – we can spend hours discussing approaches.

I was tagged spectacularly a few years back when a friend popped round to show me his new car. As I approached it, Sean sprang out of the boot where he’d been hiding and tagged me. He’d flown 800 miles from Seattle to San Francisco just to stop being “it” – to shrug off the “mantle of shame”, as we call it. My wife was so startled she fell and injured her knee, but she wasn’t angry; she was pleased to see Sean. All our partners are good-natured about the game – they even get involved in the sting operations.

How wonderful is this?

The pipeline didn’t record many metrics. The ones it did have made it look like things had gotten worse. My bug discoveries caused the overall bug count to increase. The pipeline’s failures increased because I made it fail fast on anomalies instead of silently passing along bad data. I drastically reduced the time developers spent repairing those failures, but there were no metrics that tracked developer time.

Believe me, I’ve been there — working for organizations which value the wrong things. It’s sort of surprising to see it happen at a place like Google though. Institutionally, it would seem they should better understand the issues with the metrics they collect (or do not collect.)

I spent the early part of my career working for political campaigns, where the only metric that mattered was the number of hours you worked (this is still the case today.) As long as you are on the job 18 hours per day, nobody cares if you are doing your job well or doing it efficiently. If you dared to leave the office before 8pm, you would probably find yourself fired.

I do not miss campaign life.
