As you might imagine, soldiers can’t just use garden variety earplugs to protect their ears. It might tone down the sounds of explosions and gunshots, but it’ll also prevent them from hearing a crucial command or an enemy on the other side of a doorway. It’s less of an issue for the US Army these days, though. The military branch has been gradually rolling out a smart earplug, TCAPS (Tactical Communication and Protective System), that adapts to the audio realities of war. The smartphone-linked device softens louder noises, but amplifies quieter ones; if your squad leader needs to issue a command, you’ll hear it over the din of battle. It’s a relatively simple system, but it’s very flexible. Some versions link to a soldier’s existing communications, and it’ll play nicely with hearing aids . TCAPS is far from ubiquitous. Only 20, 000 of the earplugs are in the field, and it’s doubtful that every single person in the infantry will get one when they cost around $2, 000 a pop. However, it stands a relatively good shot of catching on. More than anything, the technology provides confidence — you know you’ll get crucial audio cues without going deaf. Source: NPR

US Army’s smart earplugs spare soldiers from loud noises
Tom Mendelsohn, reporting for Ars Technica: Some smartphone users of Facebook are reporting that they’re no longer able to access their messages from the mobile site, and that they’re being directed towards the free content ad network’s dedicated Messenger app. Users of the regular Facebook mobile app were shunted over to Facebook Messenger to access their chats a while ago. Now, folk who access the service on their phone’s Web browsers, or via third-party apps such as Tinfoil or Metal, are beginning to find that they can no longer view their messages. Complaints are popping up from users who are being told by Facebook that “your conversations are moving to Messenger.” Some Android users are even finding themselves automatically redirected to the download link on the Google Play store when they try and view their messages on the mobile site.
