A beginner’s guide to using Signal

Keep your private messages private.

If you hadn’t heard of Signal before this week, chances are you’re well aware of it now. The messaging app was thrust into the news on Monday when The Atlantic’s editor-in-chief, Jeffrey Goldberg, was mistakenly added to a group chat involving top military officials planning an airstrike. Even though it entered the discourse for extremely unusual reasons, Signal has been, and remains, a well-regarded messaging platform for secure communication. It’s not foolproof — emphasis on fool, in this case — but it’s worth understanding what it is and how it works, even if you’re not a person who deals with highly confidential information.

What is Signal?

Signal is a messaging app. You download it to your iOS or Android device, link your phone number, and you’re ready to go — just like other services like WhatsApp or Telegram. The thing that makes Signal different is its emphasis on privacy. Communication on the platform is end-to-end encrypted by default, and the app offers additional protections to keep your private discussions private.

Why is end-to-end encryption important?

Aside from, say, walking over to someone and whispering in their ear, end-to-end encryption …

GE wants to put a smart display at head level while you’re cooking. The Kitchen Hub is a 27-inch touchscreen that runs Android and also functionally replaces your exhaust vent at its mounting above your stove. The company first teased the device at last year’s CES but ultimately never shipped it . It has updated this year’s version with a sleeker interface and tons of features like video calls and streaming movies. The Kitchen Hub supports Google Assistant, meaning you can ask Google to create grocery lists, look up recipes, or control other smart home devices like thermostats, lights, and cameras. The Hub can also run apps like Netflix and Spotify, so you can stream The Great British Baking Show or listen to music while you cook. There’s...

TP-Link unveils its first family of Wi-Fi 6 routers

The next generation of Wi-Fi is starting to arrive, and today TP-Link is unveiling its first family of next-gen products. There are six devices in total, ranging from high-end routers to a range extender, all of which use the new Wi-Fi 6 standard to deliver better performance and faster speeds. At the top of the line is the Deco X10, a tri-band mesh router that’ll work with the rest of TP-Link’s Deco series to spread Wi-Fi signal throughout a home. There are basically zero devices that connect to Wi-Fi 6 signals right now, so there’s not much of a reason to upgrade yet, but the Deco X10 at least provides one: it’ll use Wi-Fi 6 to create a stronger link between routers, speeding up the overall connection. You’ll need two Deco X10 units to... Continue reading… source https://www.theverge.com/circuitbreaker/2019/1/7/18167185/tp-link-wifi-6-first-router-family-ces-2019

Mophie’s battery pack case for the new iPhones lets you use wired headphones

Mophie’s newest iPhone battery case, the Juice Pack Access, represents a first for the company: an exposed Lightning port. Mophie’s cases typically plug into each iPhone’s Lightning port, and that’s how it charges the phone. This new case leaves that port exposed, so users can plug their Lightning headphones in and listen to music, even while using the case. The case will support the iPhone X, XS, XS Max, and XR. Instead of the Micro USB port that’s included with the Juice Pack Air for the iPhone X, the Access case can charge wirelessly on any Qi-enabled charging pad. It’ll charge the iPhone first and then focus on itself. It also has a USB-C port, so it can be wired and charge, too. Mophie says the iPhone XS and X case provides up to...
