The Essentials Of Multiprocessor Programming

One near constant that you have been seeing in the pages of The Next Platform is that the downside of having a slowing rate at which the speed of new processors is increasing is offset by the upside of having a lot more processing elements in a device. While the performance of programs running on individual processors might not be speeding up like we might like, we instead get huge capacity increases via today’s systems by having the tens through many thousands of processors.

You have also seen in these pages that our usual vanilla view of a processor or …

IDG Contributor Network: Compuware Total Test brings unit testing to mainframe Cobol development

Compuware, a supplier known for its focus on making mainframes a home for today's applications, not a hospice, recently announced an enhancement to its Total Test agile development tool. The goal is to provide DevOps tools to the mainframe world.Compuware Total Test Here's what Compuware has to say about Total Test: The world’s largest enterprises run their business on Cobol—but can’t nimbly update that code in response to changing business needs due to quality concerns, antiquated processes and loss of application expertise. Compuware is addressing this critical issue with the first fully automated mainframe unit testing solution that empowers in-house, outsourced, expert and novice developers alike to immediately validate code changes. This Java-like unit testing effectively eliminates the notion of Cobol as “legacy” code that can’t be updated with the same speed and confidence as other code—providing large enterprises with unprecedented agility. The release of Topaz for Total Test underscores Compuware’s leadership of a mainframe renaissance encompassing agile, DevOps, continuous delivery and the generational shift in platform stewardship. As a result of this innovation, enterprise IT organizations can now ease and accelerate the entire mainframe application lifecycle.

Dell will ship first the 32-inch 8K display, the UltraSharp 32 Ultra HD

Dell is heralding computer users into an era beyond 4K with its new 32-inch UltraSharp 32 Ultra HD 8K monitor, which is a sight to behold. But there's a caveat: Most PCs may not be ready for this cool display. The monitor will ship on March 23 for US $4,999, Dell announced Thursday. It'll be available in about 12 countries, in limited quantities. The 8K monitor has a resolution of 7680 x 4320 pixels, which is about four times that of 4K. It will feature 33.2 million pixels and more than 1 billion colors. It has a video refresh rate of 60Hz and a viewing angle of 178 degrees. It looks sleek -- it is slim and built into an aluminum cover. There's a thin 9.7-millimeter bezel around it.To read this article in full or to leave a comment, please click here

How to Extend Ansible Through Plugins


 

Did you know a large portion of Ansible’s functionality comes from the Ansible plugin system? These important pieces of code augment Ansible’s core functionality such as parsing and loading inventory and Playbooks, running Playbooks and reading the results. Essentially, Ansible uses plugins to extend what the system is doing under the hood.

In this blog, I’ll review each of these plugins and offer a high-level overview on how to write your own plugin to extend Ansible functionality.

Action Plugins

One of the core critical plugins used by Ansible are action plugins. Anytime you run a module, Ansible first runs an action plugin.

Action plugins are a layer between the executor engine and the module and allow for controller-side actions to be taken before the module is executed. A good example of this is the template module. If you look at template.py in the modules directory, it’s basically a Python stub with documentation strings, everything is done by the action plugin. The template action plugin itself creates the template file locally as a temporary file, and then uses the copy or file modules to push it out to the target system.

If Ansible finds an action plugin with the Continue reading

The downside of buying used gear via Glyde

Growing up in Rhode Island, the way to buy and sell used stuff was in the local newspaper, the Providence Journal. We had something in the classifieds called The Yankee Trader, where you could sell stuff in tiny, one- or two-line ads. You clipped out a form from the paper, filled it out and sent in $1 for the ad to run a few days later. You would contact the seller and meet to make the exchange. These days, those types of ads are dead in the water. I mean, it took 2-4 days just for your ad to run. Now there's eBay, Craigslist and a host of electronics resellers to buy and sell stuff immediately. Unfortunately, when buying from strangers all over the country, there are potential pitfalls—as I keep falling into. To read this article in full or to leave a comment, please click here

AT&T’s next 5G wireless trial will shoot DirecTV Now to users’ homes

5G conjures up visions of super-fast smartphone service, but it could give consumers and enterprises a lot more. In the next few months, some residents of Austin, Texas, will get to watch DirecTV Now at home using a form of the still-emerging wireless technology.AT&T plans to start a trial of that service in the first half of this year. Instead of the cutting-edge mobile networks that are expected to beam multi-gigabit service to moving phones, it will use a fixed wireless network built on pre-standard 5G technology to reach users' homes.MORE: Check out our interactive timeline of 5G trialsTo read this article in full or to leave a comment, please click here

2017: The year of cybersecurity scale

It’s no surprise that lots of pundits and cybersecurity industry insiders claim that 2017 will be a challenging year full of nation state attacks, ransomware, and a continuing wave of data breaches. I concur with this common wisdom, but I also believe 2017 will be remembered as the year where cybersecurity analytics and operations encountered a wave of unprecedented scale. Now, I know that the need for security scalability is nothing new. Leading SIEM vendors can all talk about how they’ve had to rearchitect their products over the past few years to scale from thousands to millions of events per second (EPS) and somehow make sense of all this activity. To read this article in full or to leave a comment, please click here
