How to extract content from compressed files on Linux

The easiest way to extract the content of compressed files (and compressed archives) on Linux is to prepare a script that both recognizes files by type and uses the proper commands for extracting their contents. Almost every compressed file will have an easily recognizable file extension — .Z, .gz, .tgz etc. And while the commands aren’t very complex, there sure are a lot of them and many options for each.So, why not attack the problem with a script that saves your precious brain cells for more challenging work? Let's look at an example that you might want to consider.To read this article in full, please click here

BrandPost: SD-WAN: Why DIY + Co-Managed Approach is a Win-Win

The SD-WAN market continues to experience phenomenal growth. A September 2017 IDC SD-WAN survey highlights that 75 percent of U.S. enterprises plan to adopt an SD-WAN solution in the next two years. Enterprises are eager to embrace and deploy SD-WAN solutions because they provide many important benefits such as improving network and application performance and availability, reducing branch office complexity, lowering bandwidth and operational costs, and improving the performance of directly connecting users from branch locations to cloud-native applications.Today, enterprises implementing an SD-WAN solution can choose between a do-it-yourself (DIY) approach or selecting a managed SD-WAN service from a managed service provider (MSP). The DIY approach is appealing to enterprises that have in-house expertise in managing their WAN network environment and have invested the time to evaluate and select an SD-WAN solution that addresses their connectivity requirements. In this model, enterprises procure, own, deploy and manage the SD-WAN equipment, software and network connectivity in-house.To read this article in full, please click here

IDG Contributor Network: Debunking today’s dominant automation myths

Automation is dominating a significant portion of the conversations trending among IT professionals. To those working in the industry, this comes as no surprise – the topic is not a new one. More and more enterprises are adopting automation as it quickly transforms from a luxury to a necessity.However, while there are well-defined benefits associated with automation, there are also important questions and misconceptions that remain. Smart IT teams must evaluate and analyze the pros, cons and impact of automation in their unique enterprise before moving forward.  The first step is debunking the most common automation myths with the facts.Myth: automation will completely replace jobs and employees This tops the list of the most significant automation myths. Some research studies do suggest that automation (especially in the form of robotics and artificial intelligence) will completely replace human jobs. This misconception must be clarified once and for all. There is no doubt that automation will have a noticeable impact on human jobs, but we can rest assured it will not replace them completely. Automation is assigning everyday tasks to computers to free up time for humans to be more creative and strategic.  This takes the meticulous tasks that Continue reading

IDG Contributor Network: ‘Tis the season for this year’s networking ‘naughty and nice’ lists

The holiday season is as good a time as any to take stock of what we witnessed in 2017, and from a technology perspective it was a year unlike any other. We saw the value of crypto currencies skyrocket and the opening of a crypto-futures market. The first shipments of 400G technologies into the wide-area-network with AT&T and Vodafone New Zealand, the continued deployment of Software-Defined Networking, a technology we’ve long championed, an early example of augmented reality go viral with Pokémon Go and Virtual Reality start to reshape the way we interact with the world around us – such as changing how we watch live sports.To read this article in full, please click here

Peeking into your Linux packages

Do you ever wonder how many thousands of packages are installed on your Linux system? And, yes, I said "thousands." Even a fairly modest Linux system is likely to have well over a thousand packages installed. And there are many ways to get details on what they are.First, to get a quick count of your installed packages on a Debian-based distribution such as Ubuntu, use the command apt list --installed like this:$ apt list --installed | wc -l 2067 This number is actually one too high because the output contains "Listing..." as its first line. This command would be more accurate:$ apt list --installed | grep -v "^Listing" | wc -l 2066 To get some details on what all these packages are, browse the list like this:To read this article in full, please click here

IDG Contributor Network: Leveraging reconfigurable computing for smarter cybersecurity

The reality for security teams today is that they are facing challenges on multiple fronts. The number of security breaches is increasing, which means the number of security alerts to be examined each day is increasing. The attacks are becoming more sophisticated and multi-dimensional. The number of cybersecurity solutions available continues to grow, which requires time and effort to understand. The amount of data in the network is snowballing, which means the cybersecurity infrastructure needs to be constantly updated to keep up. What’s worse is that all this is happening in the midst of new networking paradigms related to cloud, virtualization and software-defined data centers.To read this article in full, please click here

How to create self-driving private clouds

A few years ago, the Society of Automotive Engineers (SAE) outlined the five stages of self-driving vehicles. In actuality, there are six levels, but the zero level is no automation, so we will ignore that. The idea behind the different phases is to make it possible for us to get there in a reasonable, phased approach.It’s unrealistic that the car manufacturers could go from where we are today to a fully autonomous car with no driver or even controls. Even if the automotive community could build an autonomous vehicle today, very few people would have enough trust to use a car with no controls. When it comes to a massive shift like this, crawl-walk-run is definitely the right approach — and that’s what the five stages are designed to do.To read this article in full, please click here

IDG Contributor Network: Network analytics will change everything

The way we manage and monitor networks is morphing. Passive, reactive tools are being replaced by more proactive network analytics systems that give the entire network team a single source of truth about network behavior and a much deeper understanding of where infrastructure issues are hiding and what to do about them.Before IT was forever changed by the arrival of mobile devices, virtualization and cloud apps, fixing network problems was relatively simple because users plugged into the network from one location to access local applications and resources.But with the proliferation of diverse wireless clients – a range of hardware using different versions of different operating systems (the permutations can quickly scale into the thousands) – and the use of applications and services that are often not under IT’s control, getting to the heart of individual user and systemic client network problems has become the new nightmare.To read this article in full, please click here

IDG Contributor Network: Refactoring the network

The fundamental shift of the enterprise toward the cloud has posed a conundrum for many. The largest issue is the state of most enterprise networks. These networks were designed for an era gone by. Their original designs could not foresee the coming of technologies such as SDN, SDWAN, Segment Routing, the Cloud and an exponential increase in bandwidth that have all happened over the past 10 years.The IPv4 Internet BGP routing table alone has experienced a 10% year over year growth between 2009 and 2017 along. In 2009 the table eclipsed 286,000 routes. Here in 2017 we are at approximately 650,000. These figures only account for IPv4 routes, and not the full IPv4 and IPv6 tables. During that same period we have gone from token ring and 10Base-T to 100GbE.To read this article in full, please click here

IDG Contributor Network: IoT devices communicate by Chirping

Most IoT systems assume there will be some form of connectivity. But what happens when there isn’t any Bluetooth, WiFi or cellular connectivity? R2D2, the adorable robot from Star Wars, may have the answer with the bird-like noises he used to communicate.How can sensors share data when connectivity isn’t available? How can IoT devices be designed to last longer without being recharged? How can legacy equipment be retrofitted affordable to communicate with other devices?Most IoT devices communicate through either a Bluetooth, WiFi, LoRaWAN, SIGfox or cellular connection. The mode chosen is determined by the size of the payload to be transmitted, distance to be traversed, and the power available to the transmitting device. Walls, other electronic equipment and conflicting radio signals also influences the selection of the protocol to be used. What’s needed is that can work in ‘noisy’ environments and work with very little power.To read this article in full, please click here

Gartner analyst predicts doom for on-premises data centers

Enterprise software’s days are numbered, and if you don’t adopt artificial intelligence (AI) and machine learning, your data center will be useless.Those are the claims of Gartner Research Vice President Milind Govekar, who gave a presentation at Gartner’s annual conference for IT infrastructure operations professionals recently in Las Vegas.Govekar said that as soon as 2019, at least a third of the largest software vendors will have transitioned their products from cloud-first to cloud-only. Although he didn’t mention it by name, you have to think Microsoft is in that category because it is already cloud-first with its enterprise apps. Office 365 already outsells the packaged Office 2016, so I can see a major de-emphasis of the client product in the coming years.To read this article in full, please click here

IDG Contributor Network: 5 top data challenges that are changing the face of data centers

Data is clearly not what it used to be! Organizations of all types are finding new uses for data as part of their digital transformations. Examples abound in every industry, from jet engines to grocery stores, for data becoming key to competitive advantage. I call this new data because it is very different from the financial and ERP data that we are most familiar with. That old data was mostly transactional, and privately captured from internal sources, which drove the client/server revolution. New data is both transactional and unstructured, publicly available and privately collected, and its value is derived from the ability to aggregate and analyze it. Loosely speaking we can divide this new data into two categories: big data – large aggregated data sets used for batch analytics – and fast data – data collected from many sources that is used to drive immediate decision making. The big data–fast data paradigm is driving a completely new architecture for data centers (both public and private).To read this article in full, please click here

IDG Contributor Network: ROI linked to later stages of Industrial IoT

When most people think about the adoption of the IoT, they think about smart cities, autonomous vehicles, or the latest consumer tech and wearables. However, some of the most amazing technology applications are taking place within industrial verticals such as manufacturing, oil and gas (O&G), and transportation. Unfortunately, when asked about the state of IoT adoption within these markets, we’re often left relying on basic information about connected endpoints, instead of truly understanding how businesses are progressing through IoT maturity within the industrial field. To help answer these questions (and get a bit more in the weeds on the topic) my company, Bsquare, recently conducted its first Annual Industrial IoT (IIoT) Maturity Study. We polled 300 respondents at companies with annual revenues in excess of $250 million. Participants were evenly divided among three industry groups (manufacturing, transportation and O&G) and titles covered a wide spectrum of senior-level personnel with operational responsibilities, most of whom had spent an average of six years in their organizations.To read this article in full, please click here

IDG Contributor Network: AWS re:Invent and the 5 fronts of the cloud arms race

For the last six years running, the most important event in cloud computing has been AWS re:Invent, where the market leader announces its latest improvements. This year, 44,000 people descended upon a very crowded set of Las Vegas venues spread across multiple hotels for breakout sessions, certification exams, a diverse expo floor, and the all-important keynotes where the newest offerings were announced.Increasingly, the public cloud arms race is being waged on four fronts, with a fifth quickly emerging. All five had a healthy set of announcements—here are some of the highlights.1. IaaS/PaaS AWS started the cloud revolution with its S3 object storage service in 2006, which was quickly followed by its EC2 compute offering and a set of other IaaS products. As time went by, PaaS services like load balancers, message queues, and databases emerged as key components as well. Both classifications of services are, of course, built on physical hardware that AWS organizes into availability zones and regions.To read this article in full, please click here

AMD scores its first big server win with Azure

AMD built it, and now the OEM has come. In this case, its Epyc server processors have scored their first big public win, with Microsoft announcing Azure instances based on AMD’s Epyc server microprocessors.AMD was first to 64-bit x86 design with Athlon on the desktop and Opteron on the servers. Once Microsoft ported Windows Server to 64 bits, the benefit became immediately apparent. Gone was the 4GB memory limit of 32-bit processors, replaced with 16 exabytes of memory, something we won’t live to see in our lifetimes (famous last words, I know).Also on Network World: Micro-modular data centers set to multiply When Microsoft published a white paper in 2005 detailing how it was able to consolidate 250 32-bit MSN Network servers into 25 64-bit servers thanks to the increase in memory, which meant more connections per machine, that started the ball rolling for AMD. And within a few years, Opteron had 20 percent server market share.To read this article in full, please click here

DDI is a critical component of IoT success

The Internet of Things (IoT) era has finally arrived, and businesses need to be prepared for a world where everything is connected.I’m an analyst so I’ll support my proclamation that IoT is here with data: There are currently 25 billion internet-connected devices, and that will double by 2020 and then grow to 80 billion by 2025. ZK Research However, there’s a more basic way of understanding where we are in the adoption cycle: IoT has become the norm, not the exception, according to companies I talk to. IT and business leader no longer look at me like I have three eyes when I say, “IoT.” In fact, in many conversations with them, the term IoT never comes up — yet they are connecting things. Companies are connecting more things because it makes their businesses run better, and over the next decade, this trend will accelerate.To read this article in full, please click here
