Lessons Learned From Facebook’s Split Network Backbone

Distributed applications, whether they are containerized or not, have a lot of benefits when it comes to modularity and scale. But in a world of feature creep on all applications, whether they are internally facing ones running a business or hyperscale consumer applications like Google’s search engine or Facebook’s social media network, these distributed applications put a huge strain on the network.

This, more than any other factor, is why network costs are rising faster than any other aspect of the datacenter. Gone are the days when everything was done in three or four tiers, with a Web server like …

Worth Reading: Avoid falling into the hybrid cloud hype

Despite the many cloud benefits, most IT departments have yet to figure out how to manage their cloud usage effectively. DevOps is often still in control of cloud deployments and, in many cases, costs are spiraling out of control. A reaction has been to treat cloud management primarily as financial management by focusing on bills. To truly optimize cloud decisions and build an effective hybrid-cloud strategy, however, organizations must ignore the hype and take a methodical, data-driven approach to evaluating the options against the business requirements and the associated applications. —Data Center Journal

Sketchy report claims iPhone 8 won’t launch this year

In a brand-new research report that you might want to take with a huge grain of salt, analysts at Deutsche Bank say the release of Apple's highly anticipated iPhone 8 may be pushed back until 2018.While we've seen reports that the iPhone 8 release date might be delayed sometime until October or November, this is the first projection we've seen claiming we might not  see a brand-new iPhone 8 model in 2017 at all.The research note, obtained by Business Insider, reads in part: Report suggests no new iPhone 8 this calendar year. As we have written in previous [research notes], several supply chain reports have suggested that key component shortages and technical challenges could delay the release of a high-end iPhone 8 device this fall. We believe this report further underscores the uncertainty around the timing of Apple's next- generation iPhone model.To read this article in full or to leave a comment, please click here

Why AI careers can start with a degree in linguistics

A linguistics degree traditionally prepares students for careers in academia, professional writing or translation, but as technology continues to advance, these graduates are finding their skills in high demand from an unlikely place-positions in artificial intelligence.Companies in the AI market are turning to those with linguistic backgrounds to help aid in things like product development and customer service, says Caterina Balcells, chief linguistic officer at conversational search technology company Inbenta."Linguistics is important to better understand users and how they're communicating with a company. If we can develop tech that uses natural language processing to help customers find what they're looking for, then that reduces the need to have a person do that, and it improves customer satisfaction at the same time," Balcells says.To read this article in full or to leave a comment, please click here

How Microsoft plans to reinvent business productivity

Microsoft's Office applications haven't changed much over the past 25 years. Indeed, a time-traveller from 1992 who knew how to use Word 5.5 for DOS or Mac System 7 would have to get used only to the tools moving from vertical menus to the horizontal ribbon.  Yes, Microsoft successfully brought Office back to the Mac after years of neglect. It also used the acquisition of Accompli and Sunrise to quickly get high-quality email and calendar apps onto iOS and Android — those teams are revitalizing the Outlook applications on PC and Mac, and the new To Do service is trying to do the same thing, based on the popular Wunderlist app. Yes, there are some clever new tools in Word and PowerPoint that use machine learning to improve spell checking and automate slide design, and the monthly updates keep adding more features. And, yes, the hidden gem that is OneNote is finally getting significant investment to make the note-taking tool more useful on more platforms.To read this article in full or to leave a comment, please click here

Microsoft to cut update ties between Edge and Windows 10

Microsoft will sever the update ties between Windows 10 and its default browser, Edge, to give company developers a way to refresh the browser more often than twice a year, according to an online report."Users will finally be able to get updates to the Edge browser via the Windows Store, which will allow Microsoft to add new features more frequently," wrote Rich Woods of Neowin Monday, citing unnamed sources within Microsoft.Since the mid-2015 launch of Windows 10, Edge feature updates have been limited to the times when the operating system itself was upgraded. There have been four iterations of Edge thus far: The original of July 2015, dubbed version 12; then November 2015's version 13; August 2016's version 14; and April 2017's version 15.To read this article in full or to leave a comment, please click here

Red Hat beefs up its OpenShift containerization platform

Red Hat is beefing up its OpenShift containerization-as-a-service offering with a new developer tool for packaging apps into containers, foundations for incorporating microservices into those applications, and tighter integration of Amazon Web Services functionality with the platform. The biggest news, as far as Red Hat is concerned, is that it will offer native access to AWS from within OpenShift Container Platform later this year. That will make it possible for enterprises to configure AWS services from within the same interface they use to create and deploy containerized applications.It made the announcements at the Red Hat Summit in Boston on Tuesday.To read this article in full or to leave a comment, please click here

Troubleshooting: Basics

It’s 2AM, the network is down, and the CEO is on the phone asking when it is going to be back up—the overnight job crucial to the business opening in the morning has failed, and the company stands to lose millions of dollars if the network is not fixed in the next hour or so. Almost every network engineer has faced this problem at least once in their career, often involving intense bouts of troubleshooting.

And yet—troubleshooting is a skill that is hardly ever taught. There are a number of computer science programs that do include classes in troubleshooting, but these tend to be mostly focused on tools, rather than technique, or focused on practical skill application. I was also trained in troubleshooting many years ago as a young recruit into the United States Air Force—but the training was, again, practical in bent, with very few theoretical components.

Note to readers: I wrote a short piece on troubleshooting here on rule11, but I have taken that piece down and replaced it with this short series on the topic. I did start writing a book on this topic many years ago, but my co-authors and I soon discovered troubleshooting was going Continue reading
