How to do math on the Linux command line

Can you do math on the Linux command line? You sure can! In fact, there are quite a few commands that can make the process easy and some you might even find interesting. Let's look at some very useful commands and syntax for command line math.expr First and probably the most obvious and commonly used command for performing mathematical calculations on the command line is the expr (expression) command. It can manage addition, subtraction, division, and multiplication. It can also be used to compare numbers. Here are some examples:Incrementing a variable $ count=0 $ count=`expr $count + 1` $ echo $count 1 Performing a simple calculations $ expr 11 + 123 134 $ expr 134 / 11 12 $ expr 134 - 11 123 $ expr 11 * 123 expr: syntax error <== oops! $ expr 11 \* 123 1353 $ expr 20 % 3 2 Notice that you have to use a \ character in front of * to avoid the syntax error. The % operator is for modulo calculations.To read this article in full, please click here

New marketplace for FPGA custom apps launches

A French company called Accelize has launched AccelStore, an app store specifically around providing custom programmed applications for FPGA accelerators.FPGAs are dedicated processors known for doing two things: very fast processing, and being reprogrammable. CPUs have to be general-purpose processors that run an OS, but an FPGA has the luxury of doing a dedicated task, so the architecture is different.The problem is that while FPGAs are reprogrammable to do new, specific tasks, they aren’t that easy to program. In fact, it’s often pretty hard to do. That’s Accelize’s sales pitch. Rather than writing the code to reprogram the FPGAs in your servers, it has the templates for you.To read this article in full, please click here

VMware AppDefense Introduces Least Privilege Security for Containerized Applications

Summary: VMware AppDefense continues to advance with new capabilities, new partnerships, international expansion, and increasing customer adoption

 

As worldwide spending on IT security continues to climb, the odds of falling victim to a data breach have risen to 1 in 4. Despite a multitude of security products on the market and large budgets to purchase them, businesses are not significantly safer. The commoditization of cyber crime has made it possible for virtually anyone with a computer to launch a sophisticated attack against a company and new attacks are being developed every day. This means the continued focus on chasing threats remains relatively ineffective to stamping out the broader challenges facing IT security.

This is a scary prospect for CISOs who are faced with securing the applications and data living in increasingly dynamic, distributed IT environments. And as more businesses embrace modern, agile application development processes, the problem of implementing security at the speed of the business is exacerbated – security is often seen as an obstacle to progress.

We created VMware AppDefense to address these very issues, with a unique approach that leverages the virtualization layer to protect applications by “ensuring good” rather than “chasing bad”. AppDefense leverages VMware’s Continue reading

BrandPost: 3 ways Extreme Networks wins over other network vendors

Extreme Networks recently released a new report, “Quantifying the Value of the New Extreme Networks Solution” (an Enterprise Strategy Group Economic Value Validation report), to show the IT community how deploying our new solution can generate ROI and slash costs significantly, particularly in comparison with other network vendors.When we embarked on this journey, our goal was to make the resources of our organization part of the package. Customers should have access to a comprehensive network solution that goes beyond solving their immediate technology problems and extends into cost savings and economic benefit opportunities, period. This is why we engaged ESG to execute their Economic Value Audit process—to show you how you can realize unparalleled savings through Extreme.To read this article in full, please click here

BrandPost: Solving enterprise networking challenges with Secure Automated Campus

A recently prepared report by IDC focuses on the practical solutions for bringing enhanced automation, security and visibility into the campus network and shares the trends that are impacting them.One trend we’ve observed during the evolution of digital transformation is seeing network workloads increase significantly, parallel to the significance of the network itself. Since business is centered on a fast-paced, on-demand culture, it’s only natural that major changes in networking technology are taking hold.To read this article in full, please click here

IDG Contributor Network: Will enterprise IoT become BYOD on steroids?

If you thought BYOD was a pain the neck for IT management, strap yourself in.The integration of Internet of Things (IoT) devices in the enterprise is moving beyond the hype into a much more pragmatic and operational phase of planning, execution and service delivery.There’s massive interest and buzz around IoT within companies of every type. This is largely due to the transformative business impact IoT will have. Major business will be transformed, disrupted or out completely when IoT is properly used in the business transformation process.But with IoT solutions comes new demands and a wide range of technologies, many of which will take the enterprise into unfamiliar territory, requiring different analytical skills and management tools. In other words, IoT devices quickly finding their way into to the enterprise will make life a living hell for network managers – far beyond the problems they experienced with BYOD.To read this article in full, please click here

BrandPost: What your network needs for GDPR compliance

There is nothing like a looming deadline to get people motivated. For the General Data Protection Regulation (GDPR), May 25 is that deadline. A sweeping new data privacy regulation, GDPR will soon come into effect across the European Union (EU). In practice, however, it affects any company or organization conducting business or operations in the EU (whether through a physical presence there or offering goods and services to EU residents) that collects and processes EU residents’ data. Its goal is to better protect and empower EU residents’ data privacy, and it represents the most significant change in data privacy laws in more than 20 years. For businesses too, it will be a watershed moment in how they process, handle and manage data, with heavy fines on the table for non-compliance.To read this article in full, please click here

In the IoT world, general-purpose databases can’t cut it

We live in an age of instrumentation, where everything that can be measured is being measured so that it can be analyzed and acted upon, preferably in real time or near real time. This instrumentation and measurement process is happening in both the physical world, as well as the virtual world of IT.For example, in the physical world, a solar energy company has instrumented all its solar panels to provide remote monitoring and battery management. Usage information is collected from a customers’ panels and sent via mobile networks to a database in the cloud. The data is analyzed, and the resulting information is used to configure and adapt each customer’s system to extend the life of the battery and control the product. If an abnormality or problem is detected, an alert can be sent to a service agent to mitigate the problem before it worsens. Thus, proactive customer service is enabled based on real-time data coming from the solar energy system at a customer’s installation.To read this article in full, please click here
