Until now, Internet backups required subscribing to a cloud-based backup service and using proprietary software to handle archiving and retrieval. Now, there’s a DIY alternative: Arq backup software and Backblaze’s B2 cloud storage system.

The domain name system is largely insecure, leaking information and subject to compromise. New services from Cloudflare and Quad9 could provide greater security and integrity than Google Public DNS, currently the best known public DNS service.

The Wi-Fi Alliance has announced WPA3, a replacement for its current local network encryption options. WPA3 both fixes an exploit and increases security for those using open networks, all while reducing the burden on users. But don’t expect it to take over from WPA2 soon.

iOS 11’s Camera app now automatically recognizes QR codes, those square sets of black rectangles that contain URLs, Wi-Fi connection details, contacts, and much more. Here’s how to create and deploy QR codes in practical and useful ways.

A security researcher found a fundamental flaw in the WPA2 security specification that underlies all Wi-Fi implementations. It lets an attacker decipher encrypted data between a device and a base station. However, the opportunity to exploit this flaw is limited and closing fast for hardware that can be updated.

Users who have Find My Mac enabled but are relying on weak iCloud passwords that have been stolen in mass breaches have had their Macs locked by extortionists. We need to change iCloud passwords immediately and, longer term, give up outdated password ideas.

In iOS 11, Apple slipped notable changes into its Control Center networking controls. They’re not obvious, but you can master them.

AppleInsider found a mismatch with certain Thunderbolt 3 cables and USB-C drives that support only USB standards. We checked it out and were able to confirm AppleInsider’s results.

Apps proliferate for sending and receiving that antiquated form of document transfer, the fax. Pick the right app to keep costs down.

A news report referring to AgileBits’s aggressive shift to subscription-based licensing for 1Password overstates a requirement to store passwords at its 1Password.com site.

To save storage space and bandwidth, and to provide additional capabilities, Apple is moving forward with image and video formats that boast higher compression ratios. Glenn Fleishman dives into the details of HEVC and HEIF to explain why they’ll be so useful when they debut in iOS 11 and macOS 10.13 High Sierra.

Slack has added its most-requested feature, threaded messages, to its group messaging service, but since it’s awkwardly integrated into the system’s existing interface, the result isn’t entirely successful.

Reviewers have a responsibility to understand how their testing differs from consumer use when problems arise because introducing confusion into the world reduces trust in technology journalism as a whole.

The latest update to the long-standing synchronization and backup app ChronoSync lets you perform scheduled backups to Amazon S3 and Google Cloud and via SFTP. This is particularly interesting from the perspective of off-site backups.

The new MacBook Pro laptops are the first Macs with Thunderbolt 3, a standard that uses the USB-C plug style and retains USB compatibility. But what’s most interesting about Thunderbolt 3 is how it supports numerous other protocols, including USB, Thunderbolt 2, FireWire, DisplayPort, and Ethernet, with the addition of appropriate adapters.
