Cables and chargers go big and long

As my family acquires more gadgets and devices that require recharging, I find myself experiencing a lot more drama when one of their devices goes dead and needs to be plugged in. This turns into a battle of “cable swapping”, in which one family member removes a cable from a device being recharged and plugs it into their own device, with the hope that family member #2 doesn’t notice the swap. Buying more cable chargers can help, but then the issue becomes the availability and location of power outlets. Nowhere is this more evident than in our vehicle (a 7-year-old minivan with a recharger port only in the front), which requires a bunch of different power recharging options for occupants in the van. The driver and passenger have priority, of course, as we utilize charging for our smartphones for GPS and music streaming purposes. It's good to be the parents.To read this article in full or to leave a comment, please click here

Opportunistic Encryption: Bringing HTTP/2 to the unencrypted web

Encrypting the web is not an easy task. Various complexities prevent websites from migrating from HTTP to HTTPS, including mixed content, which can prevent sites from functioning with HTTPS.

Opportunistic Encryption provides an additional level of security to websites that have not yet moved to HTTPS and the performance benefits of HTTP/2. Users will not see a security indicator for HTTPS in the address bar when visiting a site using Opportunistic Encryption, but the connection from the browser to the server is encrypted.

In December 2015, CloudFlare introduced HTTP/2, the latest version of HTTP, that can result in improved performance for websites. HTTP/2 can’t be used without encryption, and before now, that meant HTTPS. Opportunistic Encryption, based on an IETF draft, enables servers to accept HTTP requests over an encrypted connection, allowing HTTP/2 connections for non-HTTPS sites. This is a first.

Combined with TLS 1.3 and HTTP/2 Server Push, Opportunistic Encryption can result in significant performance gains, while also providing security benefits.

Opportunistic Encryption is now available to all CloudFlare customers, enabled by default for Free and Pro plans. The option is available in the Crypto tab of the CloudFlare dashboard:

Education needs to study up on fighting ransomware

It should surprise no one that ransomware is on the rise, but it may be news that education -- not healthcare -- is outstripping other industries for rate of infection, according to a study by security ratings firm BitSight.Organizations in education had the highest rate of infection, with at least one in 10 experiencing ransomware on their networks, according to “The Rising Face of Cyber Crime: Ransomware” report.The study looks at businesses in finance, retail, healthcare, energy/utilities, government and education, which are listed in order from best to worst for ransomware infection rate. Education’s score is far behind that of the others, more than double that for government. The rate ranges from 13% of those in education down to 1.5% for those in finance.To read this article in full or to leave a comment, please click here

Worth Reading: Assessing the current state of container security

Any rational organization that wishes to run mission-critical services on containers will at some point ask the question: “But is it secure? Can we really trust containers with our data and applications?” Amongst tech folks, this often leads to a containers versus virtual machines (VMs) debate and a discussion of the protection provided by the hypervisor layer in VMs. —The New Stack

‘Digital laggards’ must harness data or get left behind

Consultants like to warn CIOs that if they don't embrace modern technologies to meet customer demands that they will be left in the dust by more nimble rivals. Such sky-is-falling proclamations have been taken lightly because they've been difficult to back up. However, new research from Harvard Business School (HBS) suggests that a divide is forming between organizations that have accelerated their digital transformations and those that are still figuring out a working digital model.Digital leaders, defined by HBS as companies that landed in the top quarter of its research, generate better gross margins as well as better earnings and net income than organizations in the bottom digital quarter. Leaders post a three-year average gross margin of 55 percent, compared to just 37 percent for the laggards. Leaders also outstrip laggards in three-year average earnings 16 percent to 11 percent. And in three-year average net income, leaders have the advantage 11 percent to seven percent.To read this article in full or to leave a comment, please click here

Cisco diversifies its internal innovation practices

Late last year, Cisco CEO Chuck Robbins significantly restructured the company and was quoted as saying the company would no longer be using “spin-ins” to drive innovation. Based on conversations with Robbins and other members of Cisco’s executive team, I believe the media took his comments out of context. There are no immediate plans for another spin-in, but he hasn’t closed to the door to them either.Robbins reiterated these points in Michael Cooney’s post, Cisco CEO: Spin-in technologies aren’t dead at Cisco, in which he stated Cisco would consider that model if it made sense. To read this article in full or to leave a comment, please click here

Apple Watch Unlock, 802.11ac, and Time

applewatchface

One of the benefits of upgrading to MacOS 10.12 Sierra is the ability to unlock my Mac laptop with my Apple Watch. Yet I’m not able to do that. Why? Turns out, the answer involves some pretty cool tech.

Somebody’s Watching You

The tech specs list the 2013 MacBook and higher as the minimum model needed to enable Watch Unlock on your Mac. You also need a few other things, like Bluetooth enabled and a Watch running WatchOS 3. I checked my personal MacBook against the original specs and found everything in order. I installed Sierra and updated all my other devices and even enabled iCloud Two-Factor Authentication to be sure. Yet, when I checked the Security and Privacy section, I didn’t see the checkbox for the Watch Unlock to be enabled. What gives?

It turns out that Apple quietly modified the minimum specs during the Sierra beta period. Instead of early 2013 MacBooks being support, the shift moved support to mid-2013 MacBooks instead. I checked the spec sheets and mine is almost identical. The RAM, drive, and other features are the same. Why does Watch Unlock work on those Macs and not mine? The answer, it appears, is Continue reading

ACLU: Cops accidentally recorded themselves making up bogus criminal charges

If cops are going to do something shady, something as unethical and illegal as violating a citizen’s First Amendment rights to free speech and his Fourth Amendment rights against warrantless seizure, then they definitely don’t want their actions being recorded. Yet that is exactly what happened when Connecticut State Police troopers seized a camera belonging to a protestor and the camera continued to film while they conspired on which bogus charges to level against him.In September 2015, Michael Picard was protesting near a DUI checkpoint in West Hartford by holding up a big handwritten sign that read “Cops Ahead: Keep Calm and Remain Silent.” Picard, who was lawfully carrying a handgun, also had a camera that he was using to film the police—public employees on a public street.To read this article in full or to leave a comment, please click here
