I think Khan is being a little too cautious. However, being a millionaire, he probably is more careful to instill certain values in his children, since they'll never do without for lack of money. I often read on the internet about how parents too often praise their kids for being smart, but I've never seen this in real life (except for my children, who are brilliant ;) I wouldn't take the research literally. I think people should take all the good lessons learned from their parents, along with some common sense, and pass them on to their children.

The students who take the ACT are not necessarily representative of the state's population. For example, I took the SAT, and not the ACT, because all the colleges I applied to accepted SAT results, but not all accepted ACT results. Students who were going to the local state school just took the ACT alone. I bet the reverse is true in different states. It doesn't take much thought to see these results are totally meaningless.

...(He also makes up to $100,000 per speech.)...Reich, a millionaire, is very concerned about rich people who, unlike him, don't really deserve their fortunes. "What someone is paid has little or no relationship to what their work is worth to society," he wrote in a recent blog post, without any apparent irony.
There is no irony. He knows well that $100,000 per speech is ridiculously overpaid. But as we all know, anyone would be a fool not to accept cash for such little work.

Comment: /usr/share/doc (Score 1) 430

On Debian, this is the directory which contains documentation outside of the man/info directories. Sometimes to get documentation for a package named foo, you have to install separately the package foo-doc. Debian does this to separate free software from documentation which does not satisfy its own guidelines for free software.

If we are talking about SHA512, than simply finding two images with the same hash would probably a result worthy of an academic publication.
This isn't true. Finding an incidental collision is not newsworthy. But giving an algorithm which constructs an image for a given hash would be worthy of publication.

Don't pay attention to any of it. Just pay your bills, and your credit score will be 800+. Mine has been 800+ for as long as I've bothered to check (15 years), with debts ranging from $0 to $100,000, including maxed out credit cards. Too many people identify credit scores with self worth. I don't think people should try to do anything special to appease these crooks. If you are financially responsible, and the credit agencies give you a low score, then to hell with them: save money and buy things outright.
