It doesn’t matter how many war machines you have under your command if you can’t relay orders to their operators. Maintaining communications is just as important as firepower, and DARPA wants the armed forces to have as many contingencies as possible when networks go down or are actively jammed. Setting up a fallback network is even trickier on the open ocean, but the agency’s Tactical Undersea Network Architecture (TUNA) program is well on its way to a solution. That solution being a collection of “node” buoys, deployed from ships or planes, that are tethered together by fiber optic cables to create a radio frequency data network. The fiber cables connecting the buoys may be thin, but are being developed to survive 30 days in challenging underwater environments, which should cover the time it takes to restore normal comms. Powering the network presents another problem, though the University of Washington’s Applied Physics Lab have created a concept buoy that draws energy from the constant ebb and flow of the ocean. The TUNA program has been in DARPA’s pipeline for the past few years , and with the first phase now complete, the next step is to build a fully working system and test it at sea. DARPA’s seafaring solution compliments another ongoing program called Dynamic Network Adaptation for Mission Optimization (DyNAMO) . Its goal is to develop a system that allows all different types of equipment found in different types of aircraft to talk to each other, creating something of a peer-to-peer communications network in the sky.

Earlier this week, on its first trading day of the new year, Bitcoin crossed above the $1, 000 mark for the first time since 2013, but it has now tumbled below that level.

Very long-time Slashdot reader Jim Hall — part of GNOME’s board of directors — has a Christmas gift. Since 1994 he’s been overseeing an open source project that maintains a replacement for the MS-DOS operating system, and has just announced the release of the “updated, more modern” FreeDOS 1.2! [Y]ou’ll find a few nice surprises. FreeDOS 1.2 now makes it easier to connect to a network. And you can find more tools and games, and a few graphical desktop options including OpenGEM. But the first thing you’ll probably notice is the all-new new installer that makes it much easier to install FreeDOS. And after you install FreeDOS, try the FDIMPLES program to install new programs or to remove any you don’t want. Official announcement also available at the FreeDOS Project blog. FreeDOS also lets you play classic DOS games like Doom, Wolfenstein 3D, Duke Nukem, and Jill of the Jungle — and today marks a very special occasion, since it’s been almost five years since the release of FreeDos 1.1. “If you’ve followed FreeDOS, you know that we don’t have a very fast release cycle, ” Jim writes on his blog. “We just don’t need to; DOS isn’t exactly a moving target anymore…” Read more of this story at Slashdot. 
Apple has disbanded its division that develops wireless routers in a move that further sharpens the company’s focus on consumer products that generate the bulk of its revenue, Bloomberg reports. From the article:Apple began shutting down the wireless router team over the past year, dispersing engineers to other product development groups, including the one handling the Apple TV. Apple hasn’t refreshed its routers since 2013 following years of frequent updates to match new standards from the wireless industry. The decision to disband the team indicates the company isn’t currently pushing forward with new versions of its routers. Routers are access points that connect laptops, iPhones and other devices to the web without a cable. Apple currently sells three wireless routers, the AirPort Express, AirPort Extreme, and AirPort Time capsule. The Time capsule doubles as a backup storage hard drive for Mac computers.
