Today at BUILD in the Day One keynote Kevin Gallo announced that you can now run "Bash on Ubuntu on Windows." This is a new developer feature included in a Windows 10 "Anniversary" update (coming soon). It lets you run native user-mode Linux shells and command-line tools unchanged, on Windows.

A security researcher has identified a Tor exit node that was actively patching binaries users download, adding malware to the files dynamically. The discovery, experts say, highlights the danger of trusting files downloaded from unknown sources and the potential for attackers to abuse the trust users have in Tor and similar services. Josh Pitts of Leviathan Security Group ran across the misbehaving Tor exit node while performing some research on download servers that might be patching binaries during download through a man-in-the middle attack. Downloading any kind of file from the Internet is a dodgy proposition these days, and many...

The ‘slow boat’ to Centauri concept we’ve discussed before in these pages envisions generation ships, vessels that take thousands of years to cross to their destination. And based on current thinking, that’s about the best we could manage with the propulsion systems currently in our inventory. Specifically, a solar sail making a close solar pass (a ‘sundiver’ maneuver) could get us up to 500 or 600 kilometers per second (0.002c), making a 2000-year journey to the nearest star possible. It’s hard to imagine under what circumstances such a mission might be launched.But let’s think long-term, as Greg Matloff (New York...
