Here’s a test trying to solve the issue… namely using a multi-page approach versus an accordion approach:

The result: Version B (the accordion) recorded a 29.1% Relative Decrease in Conversions (99% LoC)

This might seem like bad news for accordions… or single page tactics… but actually, it isn’t. I have, however, have seen this type of adjustment increase performance, but not in the checkout process itself, but in terms of eliminating that cart review step:

The result? 28.6% relative increase in conversion (95% LoC)

And I have personally run two tests with two different ecomm companies (one B2C, one B2B) where cleaning up the whole account creation process (easing the friction / requirements in it) did produce statistically significant increases in conversion.

This is a study of every high severity production incident at Microsoft Azure services over a span of six months, where the root cause of that incident was a software bug. Software bugs are the most common cause of incidents during this period, accounting for around 40% of all incidents (so we can infer there were around 280 incidents total in the pool). 7% of all software bug incidents are caused by mistakes in constants: hard-code configuration, special purpose strings such as URLs, and enum-typed values.

A new Harvard study revealed that open plan offices have the exact opposite effect on workplaces: they actually kill collaboration and productivity. Researchers Ethan Bernstein and Stephen Turban summarized their findings by stating: “Consistent with the fundamental human desire for privacy and prior evidence that privacy may increase productivity, when office architecture makes everyone more observable or ‘transparent’, it can dampen [face-to-face] interaction, as employees find other strategies to preserve their privacy; Rather than have an [face-to-face] interaction in front of a large audience of peers, an employee might look around, see that a particular person is at his or her desk, and send an email.” Through this data, you can glean insights into your team’s productivity and even monitor your workers – without paying for an office.

Say friend, did you know that the US Standard railroad gauge (distance between the rails) is 4 feet, 8 1/2 inches. The United States standard railroad gauge of 4 feet, 8 1/2 inches derives from the original specification for an Imperial Roman army war chariot. Well, there’s an interesting extension of the story about railroad gauge and horses’ behinds.

But Mijares suspected that it might actually belong to a new species, maybe even a Luzon analog to H. floresiensis. The small stature of H. luzonensis could also cause some traits of the bones to appear more primitive than they truly are, says John Hawks, a paleoanthropologist at the University of Wisconsin-Madison who was not involved in the study. For his part, Mijares is continuing to look for other signs of H. luzonensis, including a current search at Luzon’s Biak na Bato National Park, done with support from the National Geographic Society.

A few months ago I submitted a git repo with three Chapters of this book in PDF format to Hacker News, and surprisingly the repo got 500 stars in a week. There has been considerable debate over choosing R vs. Python for Data Science. If you have any idea to share or find any errors of the book, please contact me directly via email [email protected].

For nearly thirty years, a strange-looking whale skull has gathered dust in the collections of the Natural History Museum of Denmark. Now we provide the data that confirm that yes – it is indeed a hybrid,” says Eline Lorenzen, evolutionary biologist and curator at the University of Copenhagen’s Natural History Museum of Denmark. Whereas the other two species fed in the water column, the hybrid was a bottom dweller,” according to Mikkel Skovrind, a PhD student at the Natural History Museum and first author of the paper.

Apple issues voluntary recall of 2015 MacBook Pro batteries due to overheating this morning announced a “voluntary” recall of MacBook Pro batteries due to potential overheating and safety risk.
