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

Review: Google’s Home invasion

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

How and why did you initially become involved with Docker?

I was certainly aware of Docker. There were also a number of groups across SAP that were using Docker. When a member of the Docker board approached me about joining the company’s Board of Directors, I learned a fair bit more about the market opportunity Docker was pursuing and could easily see the importance of the Docker suite for corporate IT and ISV’s. I was also intrigued by the opportunity to support Ben and Solomon in building an enduring business.

 

What led you to joining Docker’s board?

For me, there are two requirements when considering board roles. The first question I Continue reading

Mobile subscriber identity numbers can be exposed over Wi-Fi

For a long time, law enforcement agencies and hackers have been able to track the identity and location of mobile users by setting up fake cellular network towers and tricking their devices to connect to them. Researchers have now found that the same thing can be done much more cheaply with a simple Wi-Fi hotspot.The devices that pose as cell towers are known in the industry as IMSI catchers, with the IMSI (international mobile subscriber identity) being a unique number tied to a mobile subscriber and stored on a SIM card. IMSI catchers can be used for tracking and in some cases, for intercepting calls, but commercial solutions, such as the Stingray used by the FBI, are expensive.To read this article in full or to leave a comment, please click here
