Normally, I don’t cover vulnerabilities about which the user can do little or nothing to prevent, but two newly detailed flaws affecting hundreds of millions of Android, iOS and Apple products probably deserve special exceptions.

I’ve lived in many cities during my military career. Each time I’ve moved, I’ve had to deal with a new city’s website, and what I’ve learned is that there are great differences across each city's site design and in how much government data is online and accessible. read more

Programming is a creative activity that any kid can engage in. Your child might not care about writing data processing algorithms, but they might enjoy creating games, programming music, designing websites, or just playing around with code. I've written several books to teach beginners of all ages how to code, and I know from experience that you don't need to consider yourself a techie or "good at math" to learn. In fact, kids often can learn to program faster than adults precisely because they don't know how "difficult" coding is supposed to be. read more
