- Temperature Zero for Culture: Why Everything Is Starting to Look the Same laurenleek.substack.com
A world that keeps removing the unlikely also removes the things that could have become the next likely. Ecologists have known this for a long time already and even priced it: they call it the insurance value of biodiversity, the standing reserve of rare species that cost energy and contribute nothing, until the climate shifts and one of them turns out to be what survives. A monoculture is efficient right up until the weather changes.
- What is the Red Bead Experiment? maaw.info
The red bead experiment is deceptively simple because it provides a powerful message that is difficult for many to grasp. In summary, the misconception that workers can be meaningfully ranked is based on two faulty assumptions. The first assumption is that each worker can control his or her performance. Deming (1986, 315) estimated that 94 percent of the variation in any system is attributable to the system, not to the people working in the system. The second assumption is that any system variation will be equally distributed across workers. Deming (1986, 353) taught that there is no basis for this assumption in real life experiences.

- The Statistics of Web Performance slideshare.net
In terms of web performance, the experience we need to measure is user perceived page load time, and the single number we need to extract depends on the distribution of measurements across the sample. There are a few contenders for what the magic number should be. Do you use the mean, median, mode, or something else? How do you determine the correctness of this number or whether your sample size is large enough? Is one number sufficient?

- How many users have JavaScript disabled? · YDN Blog developer.yahoo.com
While 2% of U.S. visitors may not seem like a lot, keep in mind that over 300 million users visit the Yahoo! homepage each month. That means 6 million users visit each month without the benefit of JavaScript. So even though it’s worth spending your time on the JavaScript-enabled version of the site, there are still a non-trivial amount of users out there who won’t be able to use it. While the percentage of visitors with JavaScript disabled seems like a low number, keep in mind that small percentages of big numbers are also big numbers.
- Cars (again) - Charlie's Diary antipope.org
Lots of interesting bits here but the stats in particular stand out. "The death toll is not small. The UK, despite having an excellent road safety record, sees more people killed on the roads every year than died during the entire duration of the Troubles in Northern Ireland; "According to the World Health Organization motor vehicle collisions are the 6th most common cause of death in developed nations, with an average rate of 20.8 per 100,000 populations in the year 2000 (30.8 for males, 11.0 for females). African nations have the world's highest road traffic injury mortality rates." (Wikipedia on traffic-related death rates.) 1.2 million were killed and 50 million injured in road traffic accidents in 2004."
- Analysis: What are the Web's Top Sources of Referral Traffic? readwriteweb.com
Not totally convinced by the results shown here but potentially a useful starting point.
Despite marketers' embrace of the medium, brands are finding themselves on the outside of the conversation. Of the 90% of Twitter messages sent by real people -- the other 10% come from businesses -- only 12% ever mention a brand, and most of those mentions are of Twitter itself. Further, only 1% of consumer tweets that mention a brand are part of an active conversation with that brand, meaning marketers are, for the most part, conducting one-way conversations -- the opposite of the way consumers often use Twitter.
- The Data-Driven Life - NYTimes.com nytimes.com
In the cozy confines of personal life, we rarely used the power of numbers. The techniques of analysis that had proved so effective were left behind at the office at the end of the day and picked up again the next morning. The imposition, on oneself or one’s family, of a regime of objective record keeping seemed ridiculous. A journal was respectable. A spreadsheet was creepy. And yet, almost imperceptibly, numbers are infiltrating the last redoubts of the personal. Sleep, exercise, sex, food, mood, location, alertness, productivity, even spiritual well-being are being tracked and measured, shared and displayed.

What makes my heart go pitty-pat is the swarm of data that the sensor in the wheel captures and transmits. Not only does it track info about the biker (riding time, effort, calories) but it also grabs info from the environment, like temperature, carbon monoxide, noise and humidity. You can share this info with friends, and also with your city by making an anonymous donation of your data. The end result? A community of data-contributors helping cities build more accurate models of routes, noise, carbon emissions and temperature. All this data can be used inform urban planning, transit systems and environmental policies in service to sustainable cities.

- The Loudness War Analyzed « Music Machinery musicmachinery.com
I’m interested in looking at the loudness for the recordings of a number of artists to see how wide-spread this loudness war really is. To do this I used the Echo Nest remix API and a bit of Python to collect and plot loudness for a set of recordings. I did two experiments. First I looked at the loudness for music by some of my favorite or well known artists. Then I looked at loudness over a large collection of music.

- High Performance Web Sites :: Wikia: fast pages retain users stevesouders.com
Wikia measures exit rate - the percentage of users that leave the site from a given page. Here they show that exit rate drops as pages get faster. The exit rate goes from ~15% for a 2 second page to ~10% for a 1 second page. This is another data point to add to the list of stats from Velocity that show that faster pages is not only better for users, it’s better for business.
