Interns loving life at Facebook, Google & Apple
While many young people are reportedly abandoning Facebook as a place to socialize online, many others say it's a great entryway to the workforce. For the second year in a row, Facebook is the highest rated company by interns based on the feedback they share on jobs and career online marketplace Glassdoor.Other tech companies also rated well, with Google (#3), Yahoo! (#6), Apple (#11), Microsoft (#13), Intel (#14) and Qualcomm (#16) among those in the top 25 (companies were rated on a 5-point scale ranging from very dissatisfied to very satisfied). One tech vendor on last year's Top 25 List that didn't repeat this year: Cisco Systems. Google, meanwhile, has slipped a bit down the list in recent years, having been the top company in 2012 and 2013.To read this article in full or to leave a comment, please click here Read More

Samsung and HTC have a lot to prove with Sunday smartphone launches
Samsung Electronics and HTC are going head to head on Sunday with almost simultaneous launches of new flagship smartphones. Both companies have a lot to prove, but for different reasons.“Samsung is fighting for its credibility and HTC for its survival,” said Neil Mawston , executive director at market research company Strategy Analytics, speaking of the duelling events ahead of Mobile World Congress in Barcelona.Mawston thinks Samsung’s critics have been a bit too harsh on the company. Despite the shortcomings of the Galaxy S5, it was the second-best-selling phone last year, beaten only by the iPhone 5S. However, the S5 wasn’t able to live up to expectations, and Samsung is now under pressure to launch something special.To read this article in full or to leave a comment, please click here Read More

Lenovo's Superfish nightmare may be the tip of the iceberg
The Superfish problem didn't happen in a vacuum. And it's not limited to just certain Lenovo notebooks sold between October 2014 and January 2015. This is because the chain of fools goes back to a root source at Komodia, now a poster child for what amounts to zero-days for the rest of us. Their ploy is pretty simple: 1.) Insert and spoof root certificates, 2.) Profit! And Superfish isn't the only problem, as ArsTechnica reported, via Marc Rogers of CloudFlare.

Apple, Linux, not Windows, most vulnerable operating systems in 2014; IE wins worst app
A whopping average of 19 security vulnerabilities were reported every day in 2014. The number of vulnerabilities discovered each year in operating systems, applications and hardware has skyrocketed in a nasty trend, according to analysis by GFI Software.Operating systems with most security vulnerabilities in 2014The top spot for vulnerabilities in operating systems no longer goes to Microsoft Windows; in fact Windows isn’t even listed in the top three. Instead, the most vulnerable OS was Apple Mac OS X, followed by Apple iOS and then Linux kernel. As you can see in the list below, Mac OS X had 147 vulnerabilities, with 64 being rated as high severity bugs. There were 127 in iOS, 32 of those rated as high. Linux kernel had a rough year, with 119 security vulnerabilities and 24 being rated as high severity. The flip-side is that none of the security holes in Windows versions were rated as low severity.To read this article in full or to leave a comment, please click here Read More

IDG Contributor Network: What Wi-Fi looks like
Hackaday member CNLohr has created some stunning images of a Wi-Fi network using a remarkably simple technique. He documented his experiments on his Hackaday project page.He achieved the results by capturing wireless signal strength using a Wi-Fi chipset hooked up to a single multi-color LED. The LED rapidly changes color depending on signal strength. He then captures long-exposure photographs of the LED, as his buddy, holding the piece of kit, moves around a space. The result is a multi-colored graphic with variations representing signal strength.Pinging the chipsetTo read this article in full or to leave a comment, please click here Read More

Apple Watch may be more water resistant than we thought
One of the longstanding questions surrounding the Apple Watch is how water resistant the device is going to be.As a quick aside, "waterproof" denotes a product that can be completely submerged under water for extended periods of time and still function as intended. So while a device filled to the brim with complex electronics, like the Apple Watch, isn't likely to be waterproof, having a degree of water resistance is extremely important.To that end, Apple CEO Tim Cook was recently in Germany where he reportedly spoke to some Apple employees and remarked that he wears his Apple Watch all the time, "even in the shower." The report comes courtesy of iGen.Fr which relayed the news earlier this week.To read this article in full or to leave a comment, please click here Read More

NSA Chief sides with FBI in encryption battle but says backdoor sounds 'shady'
Yesterday at the cybersecurity conference “New America : Big Ideas and New Voices,” Admiral Mike Rogers, the head of the NSA and U.S. Cyber Command, explained that when he attends such cybersecurity conferences he is saying, “Look, there are no restrictions on questions. You can ask me anything.” And bright minds in the audience took him up on that. Yet Reuters reported that other than claiming “we fully comply with the law,” Rogers refused to comment on Kaspersky Lab’s report about the U.S. government using implants on hard drives for surveillance.To read this article in full or to leave a comment, please click here Read More

The downside to mass data storage in the cloud
The cloud can be an enormously cost-effective way to increase storage and computing musculature, and also, sadly, a way to further add misery to those seeking privacy—or who just want to be left alone. It's rare to see organizations stand up and shout, "we'll not give your data to anyone!" or "the life of all stored data, except opt-in assets you want us to store, is always 90 days!" or "yes, we can determine in absolute certainty that your data has been erased to protect you and your identity."The cloud, in some warrens, has become a storage ground for the various factories of "big data," whose ideals are generally to sell things to consumers and businesses. Correlating facts is huge. Ask Target, whose insight into discovering pregnancies helped them capture a nicely profitable market in the pregnancy and new mother world. Smart, you say. There is a downside to this.To read this article in full or to leave a comment, please click here Read More

More companies are going 'Back to the Future' with .com domain names
One of my favorite movies from my teen years was the 1985 film, "Back to the Future." If you haven't seen it, it's about a teenager named Marty McFly who is accidentally sent back in time and skews the space-time continuum, which threatens his very existence. To get "back to the future," McFly must go through a series of difficult tasks to restore things to normal – where he needs to be to survive.I see an interesting analogy today with companies experiencing a similar "Back to the Future" moment when trying something different on the internet and then deciding to switch to what is known and trusted.Last year, I wrote this post and started keeping tabs on the ever-growing list of companies that tried an alternative generic top-level domain (gTLD), skewing their internet "space-time continuum" in the process before eventually switching back to a .com domain to get things back to normal. One might have argued that these companies were simply the exception and not the norm, but this trend isn't showing any signs of slowing down. Since my last post on this topic in December, a number of additional companies had their own Marty McFly moment and made the switch to .com after having tried an alternative domain.

IDG Contributor Network: New, faster wireless network to be built
As recently as a week ago, in a February 17th, 2015, Financial Times newspaper article, investor analysts were speculating as to just what U.S. satellite TV company Dish was going to do with its massive hoard of unused, cached mobile-suitable spectrum that it's been accumulating over the years.Well, we might have just learned the answer. Artemis Networks, a wireless startup, has reached a deal to lease some of that spectrum, for a while, in San Francisco.

Review: Nvidia's Android-powered Shield tablet is actually great for gaming
Over the past few years, I have become increasingly reliant on Android-powered tablets for a large majority of my daily activities: general browsing, social media and email, and even for the majority of my entertainment (music and movie watching).But gaming…gaming is the one area in which Android has just never really embedded itself in my home. Sure, I play some Android games here and there, but I still own dedicated, non-Android powered consoles. Part of the reason is the lack of big, Triple-A quality games available for Android; there are some, but not as many as competing gaming platforms. The other part is the lack of great gaming hardware.To read this article in full or to leave a comment, please click here Read More

Avaya takes a unique approach to ease the pain of SDN migrations
In the movie, Star Trek V: The Final Frontier, Spock's older brother, Sybok, had telepathic abilities and he could feel people's pain by touching them. In the movie he would say, "share your pain with me and gain strength from sharing." Sybok was a deeply religious Vulcan and, in the movie, sought out to find "Sha Ka Ree," the Vulcan equivalent of Eden, where everything began. Nirvana, if you will.In the networking industry, software defined networks (SDN) are supposed to bring the networking equivalent of Sha Ka Ree. However, I don't need to be a Vulcan telepath to understand customers' pain when it comes to SDNs. Almost every network professional I talk to today has an interest in SDN. However, the majority of businesses feel that deploying a software defined network is too complicated.To read this article in full or to leave a comment, please click here Read More
