We’ve all seen it. A drone flies in the air and crashes in the water. There’s a new drone from Rutgers University that flies in the air and swims in the water. The project is funded by the Office of Naval Research. It’s called the Naviator. It’s intended use is aerial reconnaissance or for snooping underwater. It can be deployed to perform ship and bridge inspections. In an oil spill, it can go underwater and see how far the spill goes.

The first website ever created by British scientist, Sir Tim Berners-Lee, celebrated its birthday two days ago. The site is 25 years old. The website was launched on December 20, 1990. The original server is maintained by CERN (European Organization for Nuclear Research). Here’s an article about restoring the first web site.
Apparently, there’s a simple way to hack a Linux distro. Just hit backspace 28 times in a row and you’re in. This applies to systems that use Grub2 boatloader, which applies to pretty much all Linux distros. On bootup, you can bypass the lock screen by hitting backspace 28 times in a row, and it will send you to the grub rescue shell. Researchers say there is a bug that creates a memory error leak, which in turn opens up a rescue shell. You’ll need physical access to the keyboard to take advantage of this bug. Ubuntu, Redhat and Debian have already release patches, so you’re out of luck.
VLC is considered by many as the swiss army knife of video players is finally coming to ChromeOS users. As you may well know, you can pretty much run VLC on any platform, from the PC, to Mac and Linux and to practically every mobile device. The last frontier was ChromeOS. The VideoLan team just made the popular player available now to ChromeOS users.
I have two access points stolen from one of my clients, a mid-size hotel somewhere in the Bay Area. Six days later, the thief decides to connect one of the access points to his network. Of course, the access point reconnected to my cloud controller giving me complete access to the stolen unit. Just to mess around with the dumb thief, I decided to change the Wi-Fi password of the access point. I also changed the SSID to “Stolen from xxx hotel.” I’m sure his neighbors are delighted to see such a unique SSID. And one more thing, I turned on the “locate” feature causing the access point to blink every second. I hope the thief sleeps through fine with a blinking blue light at night.
