Some recommendations for the network engineers

In this post, I will share many network engineering blogs which will be very beneficial for the network engineering and for those who want to learn more about network design.     Almost everyday I receive a message through social media or via email from the connections. What should we study ? I am new […]

What is MPLS Traffic Engineering and Why do you need MPLS-TE ?

MPLS Traffic Engineering is a mechanism that provides cost savings in an MPLS networks.   How cost saving can be achieved  ?  How traffic is steered to the paths which wouldn’t be used in normal circumstances ?  I will explain in this post.   Let’s look at below topology.     MPLS Traffic Engineering    […]

Is HPE’s “Machine” the Novel Architecture to Fit Exascale Bill?

The exascale effort in the U.S. got a fresh injection with R&D funding set to course through six HPC vendors to develop scalable, reliable, and efficient architectures and components for new systems in the post-2020 timeframe.

However, this investment, coming rather late in the game for machines that need hit sustained exaflop performance in a 20-30 megawatt envelope in less than five years, raises a few questions about potential shifts in what the Department of Energy (DoE) is looking for in next-generation architectures. From changes in the exascale timeline and new focal points on “novel architectures” to solve exascale challenges, …

Hackers attacked 4 Florida school districts, allegedly hoped to hack voting systems

We’ve heard a lot about Russians attackers attempting to hack the US election, but another hacking group also allegedly wanted to interfere with the election; they attempted to pivot from compromised school districts to state voting systems.The Miami Herald reported that MoRo, a group of hackers based in Morocco, penetrated “at least four Florida school district networks” and purportedly searched for a way “to slip into other sensitive government systems, including state voting systems.”To read this article in full or to leave a comment, please click here

Serial Pinout for APC

This is just a quick note to remind me how to make serial cables for APC power strips. This cable works between an APC AP8941 and an Opengear terminal server with Cisco-friendly (-X2 in Opengear nomenclature) pinout.


Only pins 3,4 and 6 are populated on the 8P8C end. It probably doesn't matter whether the ground pin (black) lands on pin 4 or 5 because both should be ground on the Opengear end. The yellow wire is unused.

Worth Reading: Not all who wander are lost

Not all who wander are lost is a favorite “Lord of the Rings” nerd-ism, and one I’ve always personally loved. Gandalf, however, never tried to learn computer programming, and also he already had a pretty sweet job in the wizardry sector. For those of us working toward that first junior web dev job, though, wandering can be a serious issue. —The New Stack

IT budgets shift away from capital expenses thanks to the cloud

IT organizations are enjoying a slow but steady increase in budgets, but their capital expenses and hiring trends are essentially flat, reflecting the effect of the shift to cloud computing. That’s the takeaway from Computer Economics’ annual IT Spending and Staffing Benchmarks study for 2017/2018. The study finds that the greatest effect has been a decrease in the total amount of spending that goes toward the capital budget."Unless you are an IT equipment manufacturer, this is good news," said David Wagner, vice president of research at Computer Economics in a statement. "The cloud transition is far from over, and we're already seeing more efficient IT departments, particularly on a cost-per-user basis, which is at a new low. Business applications and network infrastructure are the top areas of new IT spending, while the data center, for the first time, is at the bottom. We take this as a sign the cloud transformation is continuing in earnest."To read this article in full or to leave a comment, please click here

IDG Contributor Network: Partnerships among many paths to fintech tipping point

Fintech adoption and revenue have grown quickly and consistently enough to inspire some hand-wringing by banks and on their behalf, and to prompt speculation not just about which company will be the next unicorn, but how finance will react, and how the fintech industry as a whole will develop.Media coverage seeking the next dominant power — a fintech version of Amazon — may miss an important trend underlying the fintech industry growth. Fintech companies have tended to succeed through partnership and collaboration, reaching new markets and expanding services by finding mutual benefit with another company.“The fintech industry will only continue to grow, and this will be aided by an influx of collaborations between financial institutions and fintech companies to come,” wrote Alice Chen in a blog post for Due, a digital wallet for payments online.To read this article in full or to leave a comment, please click here

Tackling Computational Fluid Dynamics in the Cloud

Cloud computing isn’t just for running office productivity software or realising your startup idea. It can support high-performance computing (HPC) applications that crunch through large amounts of data to produce actionable results.

Using elastic cloud resources to process data in this way can have a real business impact. What might one of these applications look like, and how could the cloud support it?

Let’s take buildings as an example. London’s ‘Walkie Talkie’ skyscraper has suffered from a bad rap of late. First it gave the term ‘hot wheels’ a whole new meaning, melting cars by inadvertently focusing the sun’s rays …
