On any other day at Live Oak High School in Morgan Hill, Daniel Galli and his four friends would not even be noticed for wearing T-shirts with the American flag.

"You can pass this physics course without learning any physics. You just need to learn how to decode a textbook." I have felt this cognitive dissonance for years, but haven't been able to articulate it clearly. I've always said that the ability to get stellar grades has little to do with being a good engineer. Now I know why.
Course Description This subject is aimed at students with little or no programming experience. It aims to provide students with an understanding of the role computation can play in solving problems. It also aims to help students, regardless of their major, to feel justifiably confident of their ability to write small programs that allow them to [...]
The textbook business has been rotten for decades. 46 years ago the renowned Caltech physicist Richard Feynman served on a California state committee for adopting textbooks for high schools. He wrote about the incompetence and corruption in the whole process in his autobiography Surely You're Joking, Mr. Feynman!. You can read an online version of [...]
According to the filings in Blake J Robbins v Lower Merion School District (PA) et al, the laptops issued to high-school students in the well-heeled Philly suburb have webcams that can be covertly activated by the schools' administrators, who have used this facility to spy on students and even their families. The issue came to light when the [...]

The Massachusetts Institute of Technology has begun the most revolutionary experiment in the history of education, stretching all the way back to the pharaohs. It now gives away its curriculum to anyone smart enough to learn it. It has posted its curriculum on-line for free. These days, this means a staggering 1900 courses. This number will [...]
John McCardell (a president emeritus and a professor of history at Middlebury College) in the Atlantic argues that the US national drinking age of 21 is a failure... it has failed to stop underage drinking, and has instead driven it underground and made it more dangerous. I grew up with Ontario's drinking age of 19, but I started drinking at [...]
Remember: freecreditreport.com is a scam from the credit bureaus, the one they’re required, by law to offer you, for free is AnnualCreditReport.com

It might not [...]
Auto-correct typos Typing on the command line isn't easy.

But there's a way out: Bash has a built-in command called "shopt" that lets you set [...]

Wired has a great piece up on the world's burgeoning crop of Hacker Spaces -- clubhouses where members pitch in to share the rent in exchange for a role in governing a collectively managed collection of hacking kit: workbenches, tools, and components. I've visited hacker lofts in Vienna, San Diego, Los Angeles and elsewhere, and they always have a [...]
