6 machine learning misunderstandings

MisstepsMachine learning isn’t confined to science fiction movie plots anymore; it’s fueled the proliferation of technologies that touch our everyday lives, including voice recognition with Siri or Alexa, Facebook auto-tagging photos and recommendations from Amazon and Spotify. And many enterprises are eager to leverage machine learning algorithms to increase the efficiency of their network. In fact, some are already using it to enhance their threat detection and optimize wide area networks.To read this article in full or to leave a comment, please click here

US government’s Code.gov software sharing website launched

Code.gov, a U.S. government website for promoting the sharing of custom-developed software code, was launched Thursday with listings of nearly 50 open-source projects from various government agencies.The move follows the announcement by the White House in August of a Federal Source Code policy that would promote reuse of new custom source code developed by government agencies across the federal government to prevent replication of work and expense. The agencies are also required to make some of the software available to the public under an open-source license.To read this article in full or to leave a comment, please click here

Bash Script for Converting Video To MP3 Audio

I like listening to video training on my smartphone while walking to work. To save the space on the memory card I convert videos to MP3 audio in advance. For this purpose I wrote a Bash script video_to_mp3.sh which helps me to manage a conversion job. The script uses ffmpeg for conversion and it creates parallel conversion tasks to speed up the conversion process. The script checks the CPU load and it creates a new background process only if the CPU load is under a particular limit entered by a user.

Below is the output from the conversion process.

The script creates a log file displaying info about the result of all conversion tasks. If the conversion fails for a particular video file, the script displays a return value of ffmpeg utility and the name of the file which is not successfully converted.

OpenStack Summit Barcelona 2016: Current State

It’s October in the UK and blimey charlie, it’s a bit chilly. Good news then that the OpenStack Summit is in Barcelona! In comparison to Canada or Japan, it’s on my doorstep! Spain being the home of English holiday makers, the smell of sun cream, sangria and chicken nugget dinners awaits.

It Felt Different

Needless to say, I play investigator at these summits. Whether it’s the SDN congress, OpenStack or other networking events, the cynical grump hat is donned. Before I even managed to investigate anything, I felt something different. The hype lever was set to average and this show felt almost corporate. Good news or bad news? Something I’ve struggled to quantify all week and even now as I sit on the home bound flight to Blighty, I continue to ponder.

Big bang news was lacking like previous shows. Realistic use cases, real commentary and on-stage demos made this feel different. One of the demos made me both cringe and chuckle as Mark Collier played real life chaos monkey, pulling fibres and eventually even cutting through them during an EPC demo which included OPNFV Doctor and Vitrage. This demoed OpenStack’s capability to integrate with monitoring and life cycle tooling. Continue reading

Speed to drive CIO agenda in 2017

Think fast, CIOs.It’s time for organizations to move past the “false promise” of a bimodal approach to IT, which results in a divided tech department operating at two different speeds, according to research and advisory firm Forrester. Instead, CIOs need to push for enterprise-wide acceleration – and a comprehensive business technology strategy – to keep up with customers’ appetites for new products and services.“Gone are the days of stability and predictability. The business environment you operate in will change faster than ever in 2017. Many of these changes will be outside of your control, but your ability to anticipate and respond will make or break your success,” Forrester writes in a research document focused on the evolving role of the CIO in 2017.To read this article in full or to leave a comment, please click here

DDoS attack from Mirai malware ‘killing business’ in Liberia

The malware behind last month's massive internet disruption in the U.S. is targeting Liberia with financially devastating results.This week, a botnet powered by the Mirai malware has been launching distributed denial-of-service (DDoS) attacks on IP addresses in the African country, according to security researchers.  These attacks are the same kind that briefly disrupted internet access across the U.S. almost two weeks ago. They work by flooding internet connections with too much traffic, effectively forcing the services offline.To read this article in full or to leave a comment, please click here

Worth Reading: Everything you’ve ever posted becomes public from tomorrow

As I sit here, ironically just wrapping up a privacy conference, scrolling my Facebook wall, I am seeing dozens of posts from smart, professional, aware people, all posting an apparent disclaimer to Facebook in an attempt to protect their personal privacy from the new Facebook privacy policy. This disclaimer, known as UCC 1 1-308-308 1-103 and the Rome Statute, is in fact a hoax. It first surfaced in 2012 but is making the rounds again. The post encourages users to share a Facebook status which allows them to be immune from Facebook sharing any of their data uploaded to their platform. —Cloud Security Alliance

RHV and DNS

Hi folks, here’s another “pre” post. What I mean by that is that in the process of creating a demo and the surrounding article, I found I needed to create a sidebar article in order to show how configure an important component. In this case, the requirement to fulfill forward and reverse name server resolution in RHV has lead me to create a basic DNS server. In this case, “dnsmasq” is a perfect solution…

Let me be clear here: I am NOT recommending dnsmasq for production DNS. For production I would recommend deploying BIND, Red Hat IdM, or something else. I’m using dnsmasq because I need something for my home lab and I think you might benefit from the configuration I’m using in your home or test lab. I don’t have that many systems, and a lightweight service like dnsmasq will work nicely.

Background

The RHV 4 documentation is very clear about the requirement for FQDN and fully functional DNS. Simply relying on “/etc/hosts” isn’t going to cut it anymore. Dnsmasq will provide a great and simple solution for small labs. For the uninitiated, dnsmasq provides DHCP, TFTP, DNS, and DNS forwarding. We’ll really only be concerned with the DNS Continue reading

Report: Nearly 90 percent of smartphones worldwide run Android

Android just reached a new milestone in its worldwide dominance over iOS.According to new research from Strategy Analytics, 87.5 percent of smartphones in the world are now running Android. Shipments hit a total of 328.6 million for 3rd quarter of 2016, which is up 10.3 percent up year-on-year. While Android had always been hanging around the 80 percent mark, this latest number is a new high.Comparatively, Apple shipped 45.5 million iPhones, which is down 5.2 percent from the 48 million from last year. The real drop is in "others" (like Blackberry and Windows phone). Last year, 8.2 million units of "other" smartphones were sold in the 3rd quarter. This year, the number is 1.3 million.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Wired internet will be replaced by mobile

Seventy-five percent of internet use will be on mobile devices next year, according to a new study published by ad forecaster Zenith.The firm says that’s just the beginning. It reckons that some places, such as Hong Kong, will have 89 percent of total internet use being performed on mobile by 2018. The United States will marginally trail that at 83 percent in that year.+ Also on Network World: Desktop use off 11% in past year. Winner: smartphones + Smartphone penetration is the cause. Those devices have proliferated rapidly. In 2012, only 23 percent of individuals in Zenith’s 60-studied countries possessed smartphones. That number is now 56 percent and will be 63 percent globally by 2018. Some countries have adopted the devices more spectacularly; for example, Ireland is at 92 percent smartphone penetration.To read this article in full or to leave a comment, please click here
