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 […]

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

Review: Netgear Nighthawk X10 packs a speed punch, has nice add-on features

How many years have gone by since you’ve upgraded your Wi-Fi router? If it’s been a few years and you want to also future-proof the network for upcoming technologies, a router on your short list should be Netgear’s Nighthawk X10 (model R9000, $499.99).The X10 not only has very fast dual-band (5GHz and 2.4 GHz) networking, but it also adds 802.11ad (60GHz) support, which provides for very fast data transfer rates over very short distances. This can be perfect for transferring large amounts of files over your LAN (such as between computers or a centralized storage device). Netgear also says that VR gaming will benefit from 802.11ad technologies (for when the headsets go wireless and need a high-speed connection to the PC from the headset) in the future. MU-MIMO technology is also supported, which maintains high data transfers when multiple-devices are also trying to do things on the network (such as stream video).To read this article in full or to leave a comment, please click here

European legislators debate robot rights for autonomous vehicles

Robots should one day have rights as "electronic persons," members of the European Parliament recommended Thursday -- but not until the machines are all fitted with "kill" switches to shut them down in an emergency.Parliament's Legal Affairs Committee wants the European Commission to propose legislation that will settle a number of ethical and liability issues in the field of robotics -- including who is to blame when an autonomous vehicle is involved in a collision.Granting the more sophisticated autonomous robots some kind of electronic personhood could settle issues of who is responsible for their actions, the committee suggested. More urgent than the question of robot rights, though, is the setting up of an obligatory insurance scheme that would pay out to the victims of a self-driving car if it caused an accident in the European Union.To read this article in full or to leave a comment, please click here

Apple must face claims of monopoly in iPhone app market

An appeals court has ruled that Apple must face antitrust charges in a lawsuit that alleges that the company monopolized the market for iPhone apps.The U.S. Court for Appeals for the Ninth Circuit reversed Thursday a decision by a lower court and ruled that the app buyers filing the lawsuit are direct purchasers of iPhone apps from Apple, rather than from app developers, and hence have standing to sue. Apple was a distributor of iPhone apps, selling them directly to buyers through its App Store, according to the court.The proposed class-action lawsuit started in 2011 with the complaint changing several times.NEWSLETTERS: Get the latest tech news sent directly to your in-box The purchasers object to the 30 percent "surcharge" that they pay to Apple. The company collects 30 percent of the revenue of third-party apps on its store, with the balance going to the developer, in a closed system in which Apple controls which apps can run on an iPhone, according to court records.To read this article in full or to leave a comment, please click here
