Facebook change will give you control over data sharing with apps

Users are getting greater choice over what information is shared with websites and apps when they log in using their Facebook ID.A new version of Facebook Login, which begins its wide roll out this week, will present users with a prompt to “Edit the info you provide.” Clicking that will let users grant or deny access to different types of information. The login now also highlights who will see content posted by the app in Facebook, for apps that request the ability to do so.Facebook first announced this system during its F8 developers conference in April 2014. Many of the most popular apps, like Pinterest and Netflix, are already using it and over the next few weeks, Facebook will turn on the system for every app that uses the Facebook Login.To read this article in full or to leave a comment, please click here

Citizens of Tech 001 – Knuckle Cracking Felt Animals

I have a new podcast recommendation to share. The title is Citizens of Tech and is a product of our good friend Ethan Banks and Eric Suthphen. Although it is part of the PacketPushers ecosystem, it is a very different type of podcast. As opposed to typical network-centric topics, this show seems to include all things tech (and things that tech people are interested in).

Check out the first episode here–

GogglePal: Augmented reality and heads-up meets the snow

It seems like every sport is in the process of getting a high-tech digital makeover and snow sports are no exception. For example, a 3-day old Kickstarter campaign by GogglePal for an augmented reality (AR) heads up display (HUD) that can be mounted on any brand of ski googles is already over halfway to its funding goal of $40,000 and runs through May 28.The GogglePal system (I keep wanting to write “GooglePal” which is what it could become if a certain company gets interested) consists of the HUD module that sits inside your goggles a magnet that sits on the outside of your goggles to hold the HUD in place and a controller “pod” that you clip to your goggle strap.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Lasers will allow real-time satellite communications

There's an inherent problem with Low Earth Orbit (LEO) satellites of the kind used for remote observation, such as border security and disaster monitoring.The problem is that because of their low orbit—they're a few hundred miles above earth's surface, rather than 22,300 miles as found with Geostationary (GEO) satellites—they can't see their ground station at all times.They can see the earth more clearly, so they are good for monitoring; they are cheap to deploy because they don't need such a big rocket to get it up there; and they don't suffer from as much packet latency as GEO satellites because the distances are shorter.However, they aren't visible from any given point on earth at all times—they're not stationary, and they're low-down.To read this article in full or to leave a comment, please click here

House committee approves bill to end NSA phone records program

A U.S. Congress committee has overwhelmingly approved legislation designed to stop the bulk collection of U.S. phone records by the National Security Agency.The 25-2 vote in the House of Representatives Judiciary Committee sends the USA Freedom Act to the House floor for a vote. The two votes against the bill came from lawmakers who had argued for stronger protections for civil liberties.The legislation is a stronger version of a similar bill that passed the House last May but stalled in the Senate, sponsors said. However, several efforts to further strengthen privacy protections by amending the bill failed in committee. Opponents said changes would upend a carefully crafted compromise with House Republican leaders who have threatened to kill an amended bill.To read this article in full or to leave a comment, please click here

Wireless engineers now have a new online hotspot for geeking out

There are plenty of places online to bounce ideas off of other network and IT pros, but Kevin Franzen felt there was a need for at least one more, and he calls it the WirelessGeek.net forums.“I am trying to provide an open forum for engineer types to discuss wireless networks,” says Franzen, a certifiably smart wireless network guy (CWNE #136 and CCNP-Wireless) who works in Austin as principal network engineer for a large telco that is not affiliated with the forums.  “Currently folks try to use Twitter for this but it is not effective. The other wireless forums are related to vendors or a training company.”To read this article in full or to leave a comment, please click here

Microsoft relents a little after Windows 10 phone design backlash

Microsoft is making some changes to its Windows 10 smartphone apps after provoking outrage with its initial designs.Specifically, Outlook’s Mail and Calendar apps will put common commands at the bottom of the screen, where users can easily reach them with one hand. In a blog post, Microsoft has shared some mockups of a future design, showing a bottom bar for actions such as compose, delete, search, next message, and calendar views.An earlier Windows 10 preview for smartphones had these commands closer to the top of the screen, well out of one-handed range. “Without a doubt, the highest volume of dissatisfaction we’ve heard about Outlook Mail and Calendar for phones” came from people upset with this change, wrote Albert Shum, head of the design team in Microsoft’s Operating Systems Group.To read this article in full or to leave a comment, please click here

Apple, IBM to bring iPads to 5 million Japanese seniors

An initiative between Apple, IBM and Japan Post Holdings could put iPads in the hands of up to 5 million members of Japan’s elderly population.The iPads will run custom apps from IBM tailored to the needs of Japan’s elderly, who make up about a quarter of the country’s population, IBM said. The programs will remind people to take medication, offer diet and exercise information and connect them to services like grocery delivery, among other tasks. The tablets will also come with standard Apple software like FaceTime for communication, iTunes for organizing music and Photos for managing pictures.Japan Post will manage the devices and its 400,000 employees will receive training from IBM on how to use them. Japan Post, a government-owned holding company that offers banking and insurance services in addition to handling postal operations, will begin testing the iPads in the second half of the year. Details on the size of the trial weren’t provided.To read this article in full or to leave a comment, please click here

Writer rescues Verizon customer in distress

A Virginia woman writes to Christopher Elliott, an author, journalist and consumer advocate who gets results: Help! Verizon lost the cable boxes and remotes I returned to it via UPS after I moved out of my apartment. Now it’s trying to stick me with a $2,000 bill, even though UPS tracking showed it had been delivered, and even though the Verizon representative I spoke to agreed and updated my account to show that they had received the equipment.Here’s the problem: I discarded the UPS tracking information after speaking with the Verizon rep in early December, never dreaming that it would come back to haunt me on my January bill.To read this article in full or to leave a comment, please click here
