Geekiest alarm clock ever?

Everyone knows what to do when life gives you lemons. Well, the same can apply when technology cries wolf at four in the morning, according to a contributor to Reddit’s section devoted to systems administration. Every morning at just past 4 a.m., I get a text from Solarwinds that makes my phone beep. The alert is that one of our LDAP servers is unresponsive. Then two minutes later I get a text/phone beep that LDAP is back up. Every day.It’s OK, I need to catch the bus/train just past 5 a.m. anyway, gives me time to get ready / pack my lunch, drink a cup of coffee, etc.To read this article in full or to leave a comment, please click here

Can VR make the jump from oddity to mainstream? I’m having doubts

In virtual reality’s latest iteration, it’s clear that 2016 and the first part of 2017 (based on the number of companies and products displaying at CES) is seeing the beginnings of mainstream interest in the concept.But after having tried several different VR headsets and offerings, I’m starting to have doubts about whether the technology can make the jump from a niche audience and market (mainly gamers) into the larger space held by the rest of the world. The rest of this year (and possibly 2018) could determine whether VR becomes as prevalent as the smartphone, or whether it becomes another gadget that gets placed in the recycling bin labeled “fads.”To read this article in full or to leave a comment, please click here

State of the CIO 2017: The new reality

As technology grabs the lead role in modern business, all eyes are on the CIO's ability to lead initiatives that radically transform how companies sell products, reach customers and drive opportunities for new revenue streams. At the same time, the digital era's wholesale dependence on technology means there's little room for the slightest hiccup in operations -- resulting in another mandate on the CIO's agenda.One functional responsibility that CIOs don't expect to spend less time on in the future is security management: 26 percent of the respondents to this year's survey said they expect to devote more time to that task in the next three to five years, up from 21 percent in last year's survey.To read this article in full or to leave a comment, please click here(Insider Story)

AMD reveals another edge for Ryzen vs. Intel’s Skylake: It will be smaller

AMD’s upcoming Ryzen CPU will occupy less space and offer twice the amount of cache of Intel’s 6th-generation CPU, according a news report. Oh, and there will indeed be a quad-core model.AMD engineers made the disclosure in a paper this week during the International Solid-State Circuits Conference in San Francisco, according to EE Times' Rick Merritt.The engineering paper said a quad-core Ryzen chip built on a 14nm process would be about 10 percent smaller than a comparable 6th-generation Intel Skylake CPU built on a 14nm process, while offering twice the L2 cache of the Intel chip. The paper appears to count only the amount of space used for the x86 cores on an Intel CPU in its comparison. Like other mainstream CPUs, Intel’s Skylake chips also include graphics cores aboard.To read this article in full or to leave a comment, please click here

What company execs can learn from Trump’s tweeting

Like him or hate him, there's no debating that President Trump loves to tweet. What is up for debate, though, is whether his tweet storms will complicate what is already stressful work for the Secret Service. Enormous effort goes into protecting the President and his staff from hackers, and any tweets that could be deemed argumentative, hostile, or reactionary could elevate the risk of a targeted cyber attack on the White House. In the same way, executives at major enterprises also need to be cautious in how they choose to represent the company through social media. This type of security, said Larry Johnson, ex Secret Service agent and CSO of CyberSponse, is not just protecting the individual. Whether it's the Secret Service or the security team, "They’re protecting the company, the country, the assets."To read this article in full or to leave a comment, please click here
