I used to be into working on cars. If you ever wondered how and why headers improve performance, here’s a low-level tutorial. The motivation for this is that there’s a famous graduates display case at my kids’ high school, and... Continue reading

Not yet for sale, but the future looks pretty cool. Grandchildren are hopefully still several years out for me, but I’ll bet they’ll never know there was a time when we didn’t have this on our phones: This fairly sharp,... Continue reading

I had not heard this story; perhaps it’s apocryphal: The troops in the first Iraq war wore T-shirts saying “who you gonna call? 001.” It’s still the only number. From John Cochrane’s contribution to a gathering on American exceptionalism. FYI:... Continue reading

From Quora: Germany, Austria and Italy are standing together in the middle of a pub when Serbia bumps into Austria and spills Austria's pint. Austria demands Serbia buy it a complete new suit because there are splashes on its trouser... Continue reading

Interesting. There’s a platform to create internet contact that isn’t linked … to anything … even itself. Not only isn’t it linked, search engines spiders are pointed away from it. It’s a project of Rob Beschizza, who’s an editor at... Continue reading

Why are so many prime age (25 to 54) men not in the labor force? This has gone from 3% to 12% over the last 50 years. One reason may be jail time. How so? First off, labor force participation... Continue reading

Spiders eat 400-800 million metric tons of animals every year (mostly insects of course). This isn’t just trivia. Lots of people are concerned about the ecological impact of human meat consumption. So it’s important to note that humans consume less... Continue reading

Dropped the vXgirl off at high school on Wednesday. Many last minute students walking by the front of my car. One carrying a live turtle in his left hand. Not a baby, but rather a squirming adult about 10 inches... Continue reading

Attributed to Jan L. A. van de Snepscheut:† In theory, there is no difference between theory and practice. But, in practice, there is. In a nutshell, this is the problem with teaching macroeconomics. Is there any other field where the... Continue reading

That’s how much pee is estimated to be in the typical swimming pool. What’s that? About 80 “episodes”? Even so, it’s a concentration of less than 1 in 10,000. BTW: clever bit of science to figure this out. FWIW: eye... Continue reading

What if a biological man who presents as a woman rapes a man?* If convicted, where do they serve their time? This is a case from the UK. But I’m pretty sure that they way the law has evolved over... Continue reading

Correct me if I’m wrong, but doesn’t this qualify as a commercial, inside Windows Explorer on my own PC? Also note that they’re trying to sell me something, OneDrive, that I already have (it’s in the sidebar). I am really... Continue reading

Deirdre McCloskey on free trade. She makes the excellent point that jobs are infinite: all we have to do is do them less efficiently. When you put it that way, it doesn’t make sense any more, does it? Technorati Tags: mccloskey,free,trade,jobs,manufacturing,infinite Continue reading
