IDG Contributor Network: Infrastructure monitoring: Turn data into knowledge and minimize slowdowns

It’s 2 a.m., and a hospital’s system has slowed to a crawl. Lives are at stake. For the harried system admins looking for the source of the slowdown, time is of the essence.The hospital’s system has servers attached through a SAN to storage devices. But where’s the weak link? The administrator cannot afford to waste time analyzing server performance when the problem may be in a storage device or the SAN. He needs information that enables him to conduct his root cause analysis as quickly as possible.Perhaps you don’t have to worry about whether someone will live or die when your IT infrastructure fails. However, when it’s slow or down, it fails to deliver a satisfying user experience. Also, it’s likely that your company’s operations falter, costs increase, and your bottom line suffers.To read this article in full or to leave a comment, please click here

Is this the year IoT standards will finally make sense?

A few brave souls predict IoT standards will start to gel this year, but making all those connected things work together still looks like a long shot.Two years ago, some industry analysts cautiously suggested that a vast array of IoT standards would merge into just a few beginning in 2017. If the internet of things in late 2014 was a cacophony of discordant musicians tuning up, it’s now reached the point where a few virtuosos are playing the same tune. But there’s still a lot of sheet music getting passed around.To read this article in full or to leave a comment, please click here

The Interplay Of HPC Interconnects And CPU Utilization

Choosing the right interconnect for high-performance compute and storage platforms is critical for achieving the highest possible system performance and overall return on investment.

Over time, interconnect technologies have become more sophisticated and include more intelligent capabilities (offload engines), which enable the interconnect to do more than just transferring data. Intelligent interconnect can increase system efficiency; interconnect with offload engines (offload interconnect) dramatically reduces CPU overhead, allowing more CPU cycles to be dedicated to applications and therefore enabling higher application performance and user productivity.

Today, the interconnect technology has become even more critical than ever before, due to a number …

Stumbling And Fumbling Into Video Blogging

I’m used to writing and to podcasting. I know what the content creation and publication process looks like for written and audio media. The increasing popularity of video has had me and my business partner scratching our heads, wondering how we can best leverage the medium. Or if we even should.

And so, we’ve begun our video adventure the way we’ve always done things. Just go for it. Try it. Hit publish. It won’t be perfect, but that’s okay. Learn and improve.

My first video was a good bit of work, taking roughly eight hours to write, shoot, produce, and publish a ten minute video covering some tech industry news. That’s not scalable, but it was a learning experience. Here was my process.

Write

I get press releases from dozens of marketers and public relations firms, usually several per day. I chose some that I thought folks might be interested in. And then I wrote copy. I know from past projects that many written words translate to many spoken minutes. You have to keep copy tight if you’re writing to a time limit.

I managed to do that, writing just under a thousand words of copy. I did ad lib a bit, but Continue reading

Worth Reading: Class breaks

There’s a concept from computer security known as a class break. It’s a particular security vulnerability that breaks not just one system, but an entire class of systems. Examples might be a vulnerability in a particular operating system that allows an attacker to take remote control of every computer that runs on that system’s software. Or a vulnerability in Internet-enabled digital video recorders and webcams that allow an attacker to recruit those devices into a massive botnet. —Schneier on Security

Is LISP (Locator Identity Separation Protocol) Dead?

Today, there are many networking technologies which haven’t been widely deployed. And among them are Internet Multicast and IPv6 although these two protocols have many benefits .  But probably people are asking the correct question. Do we really need new protocol ? Or can we solve our problem with the existing mechanisms deployed on our […]

IDG Contributor Network: 3 security analytics approaches that don’t work (but could) — Part 1

Digital technologies have changed the face of business and government, and they will continue to do so at an even faster pace. They drive innovation, boost productivity, improve communications and generate competitive advantage, among other benefits.The dark side of this digital revolution has now come clearly into focus as well: McKinsey estimates that cyber attacks will cost the global economy $3 trillion in lost productivity and growth by 2020, while theft, sabotage and other damage inflicted by trusted insider personnel continue to cost organizations in lost revenues, revealed secrets and damaged reputations.To read this article in full or to leave a comment, please click here

WhatsApp vulnerability could expose messages to prying eyes, report claims

When Facebook’s WhatsApp turned on end-end-end encryption in its messaging service last year, it was a big deal. As all eyes were glued on Apple’s fight with the FBI over unlocking the San Bernardino shooter’s iPhone, WhatsApp took a huge step toward protecting its users’ privacy by moving to encrypt all messages and calls being sent between its apps.But a new report suggests it might not be as secure as users think. According to The Guardian, a serious vulnerability in WhatApp’s encryption could allow Facebook to intercept and read messages unbeknownst to the recipient, and only aware of by the sender if they have previously opted in to receive encryption warnings. The security flaw, which was discovered by Tobias Boelter, a cryptography and security researcher at the University of California, Berkeley, can “effectively grant access (to users’ messages)” by changing the security keys and resending messages.To read this article in full or to leave a comment, please click here
