Microsoft cleans house at the Windows Store

Microsoft announced earlier this year that it would remove applications from the Windows Store that do not comply with the age rating policies the company had adopted. The age rating policy is based on appropriate age and content ratings administered by the International Age Ratings Coalition (IARC) rating system. Microsoft said these ratings are about the suitability of the content in the app, rather than the age of the target audience for your app.  Well, it meant what it said. A large number of applications have been removed from the Windows Store, with reports ranging from 90,000 apps and games to more than 100,000. Given the Windows Store has (or had) 329,000 apps, that's about one-third of the total apps. To read this article in full or to leave a comment, please click here

Mozilla plans to rejuvenate Firefox in 2017

Mozilla last week named its next-generation browser engine project and said it would introduce the new technology to Firefox next year.Dubbed Quantum, the new engine will include several components from Servo, the browser rendering engine that Mozilla has sponsored, and been working on, since 2013. Written with Rust, Servo was envisioned as a replacement for Firefox's long-standing Gecko engine. Both Servo and Rust originated at Mozilla's research group."Project Quantum is about developing a next-generation engine that will meet the demands of tomorrow's web by taking full advantage of all the processing power in your modern devices," said David Bryant, the head of Firefox engineering, in a piece published Thursday on Medium.To read this article in full or to leave a comment, please click here

Worth Reading: Dyn’s DDoS Reveals IoT Weak Points

The massive internet outage last Friday that took out Twitter, GitHub, Spotify and others, was caused by a tsunami of incoming requests to Dyn, the DNS service provider supporting these companies. Where did all these requests pour in from? Hacked CCTV video cameras, digital video recorders and other IoT devices. The Internet of Things has arrived. And it brings huge security issues. —The New Stack

IBM deploys machine learning to bolster online banking security program

Behavioral biometrics that uses machine learning is behind new features being added to IBM’s Trusteer Pinpoint Detect platform, which financial institutions use to head off crooks who may have stolen the username and password of legitimate account holders.The new feature looks for anomalies between legitimate users’ normal mouse gestures and those of the current user, and over time refines the accuracy of its analysis, says Brooke Satti Charles, Financial Crime Prevention Strategist for IBM Security.That analysis creates a risk score that banks can use to decide whether an ongoing transaction is fraudulent and trigger an alert. The institutions have to decide what to do about the alerts, but they could cut off the transaction or require further ID before the customer is allowed to continue, she says.To read this article in full or to leave a comment, please click here

CCDE – CCDE Practical Studies – Practice Lab 1 by Martin Duggan

One of the most challenging aspects when studying for the CCDE practical is to find scenarios to practice with. It’s difficult to find a scenario that has enough background information, requirements and constraints to emulate the experience of the real practical. Writing a full scale scenario is very time consuming and challenging. You have to find a good story, make it believable and challenging enough. The scenario must also be somewhat realistic.

I’m happy to announce that my friend Martin Duggan has released a new scenario for the CCDE practical. Martin and I studied for the CCDE together and passed on the same day. Martin is well known in the industry and holds a CCIE in RS and works as a network architect at AT&T. He is a Cisco Press author and has authored the CCIE RS Practice Labs Bundle. I have been a technical reviewer for this scenario and based on my experience this is one of the best quality scenarios I’ve seen.

These are some of the things that I think Martin has done really well to make this scenario as realistic as possible.

Background information – The scenario contains more background information than some of the other Continue reading

Dell/EMC, SnapRoute reinforce OpenSwitch networking features

Looking to broaden the qualities of its open source stack, the OpenSwitch project said SnapRoute and Dell EMC will add new features to its network operating system.Specifically, the new contributions include: SnapRoute’s open source network stack and management services, which support a modular, hardware independent NOS, accessible through a complete set of APIs. Dell EMC’s OS10 Open Edition, which represents an open, disaggregated base subsystem incorporating hardware and platform abstraction layers for networking switching applications. On top of OS 10 base module run application modules which include traditional Layer 2/3 networking functions and other IP, fabric, security, and management and automation tools from Dell, Linux, third-parties and the open source community. “OpenSwitch is now one step closer to providing the data center community with an open source network operating system that enables organizations to focus on developing innovative networking solutions, which can exploit Cavium’s extensible switch architecture to address rapidly changing market needs," said Albert Fishman, Linux Foundation OpenSwitch project marketing chair and senior technical marketing manager of Cavium Switching Platform Group.To read this article in full or to leave a comment, please click here

IBM, LEGO offer Macs as recruiting tool

In a job-seeker’s market, employers will do everything they can to attract and retain skilled talent. For some companies, that extends to the technology they offer to employees.At IBM, employees can now choose Apple devices, thanks to an initiative launched in June of 2015. In the first few months of the user-choice program, IBM deployed 30,000 Macs to its workforce. Today, IBM has 90,000 Macs deployed and is on pace to exceed 100,000 by year end.The Mac@IBM program is part of a larger effort to transform company culture, according to Fletcher Previn, vice president of Workplace as a Service at IBM.To read this article in full or to leave a comment, please click here

snaproute Go BGP Code Dive (13): Finding the tail of the update chain

Just in time for Hallo’ween, the lucky thirteenth post in the BGP code dive series. In this series, we’re working through the Snaproute Go implementation of BGP just to see how a production, open source BGP implementation really works. Along the way, we’re learning something about how larger, more complex projects are structured, and also something about the Go programming language. The entire series can be found on the series page.

In the last post in this series, we left off with our newly established peer just sitting there sending and receiving keepalives. But BGP peers are not designed just to exchange random traffic, they’re actually designed to exchange reachability and topology information about the network. BGP carries routing information in updated, which are actually complicated containers for a lot of different kinds of reachability information. In BGP, a reachable destination is called an NLRI, or Network Layer Reachability Information. Starting with this code dive, we’re going to look at how the snaproute BGP implementation processes updates, sorting out NLRIs, etc.

When you’re reading through code, whether looking for a better understanding of an implementation, a better understanding of a protocol, or even to figure out “what went wrong” on Continue reading

Messaging and collaboration tools are most valuable enterprise apps

Messaging and collaboration applications are the most mission-critical mobile apps in enterprise today, according to a new survey of executives commissioned by Adobe.

Internet of Things poised to transform cities

The internet of things (IoT) is set to transform municipal life, according to government officials surveyed by the nonprofit trade association Computing Industry Trade Association (CompTIA)."Cities and city leaders are thinking more holistically about different uses of technology that are integrated and bringing different aspects of the city together into a unified whole," says Tim Herbert, senior vice president, research and market intelligence, CompTIA."Improved decision-making made possible through new or better streams of data ranks as the highest perceived benefit," he adds.How to build a smarter city In June and July of this year, CompTIA surveyed 172 government personnel with some degree of technology decision-making responsibility for its Building Smarter Cities report. It found that one-half of local, state and federal government personnel believe IoT and the smart cities enabled by IoT will definitely provide value. A further 39 percent felt IoT and smart cities would probably provide value.To read this article in full or to leave a comment, please click here
