Intel is said to mull sale of its security business

Intel is considering selling its security business as the company tries to focus on delivering chips for cloud computing and connected devices, according to a news report.The Intel Security business came largely from the company's acquisition for US$7.7 billion of security software company McAfee. Intel announced plans to bake some of the security technology into its chips to ensure higher security for its customers.With the surge in cyberthreats, providing protection to the variety of Internet-connected devices, such as PCs, mobile devices, medical gear and cars, requires a fundamentally new approach involving software, hardware and services, the company said in February 2011, when announcing the completion of the McAfee acquisition.To read this article in full or to leave a comment, please click here

Crafting responsive email with CoffeeCup’s RED

If you’ve ever sent bulk email such as newsletters, updates, sales pitches, etc., then you’ll be aware that this isn’t as simple as it used to be. Many moons ago, you could slap some text into a page along with a few links and that was good enough. Then came HTML mail and the ante was upped but you still didn’t have to break a sweat to ensure that the user could read your content. But now …To be competitive these days you have to deliver slick, styled, typographically sophisticated content with color, responsiveness, animation … you name it. And you’ve got to take into account not only how email renders on desktop clients (just consider the horrors of Microsoft Outlook’s eccentric rendering of otherwise valid HTML and CSS content) but also what happens to content in various Webmail services and, most importantly these days, on mobile devices. And just to make it all that little bit harder, many mobile platforms have specific version-dependent quirks that break the best-laid plans o' mice and designers.To read this article in full or to leave a comment, please click here

iPhone 7 Rumor Rollup: 10th anniversary is when the iPhone fun will really start

Much of this past week in iPhone 7 rumorville was occupied with rehashing and debunking a lot of the most popular scuttlebutt (dual cameras, no more 3.5mm headphone jack, etc.) about Apple’s next flagship smartphone, which is expected to debut in September. Plenty continues to be said as well about how boring the new iPhones promise to be (though Apple will need to try really hard to make it duller than its recent Worldwide Developers Conference bounty). Macworld’s Macalope column rips into those who don’t have faith in Apple to do the right thing, including a writer for The Verge who urges Apple shoppers to have “Have some dignity” over buying what Apple is reportedly selling this time around.To read this article in full or to leave a comment, please click here

My SDN Testbed

Over the next few articles, I will write about OpenFlow, Open vSwitch and other SDN related topics. As always, I'm combining the theory part with some hands-on practice and for this, I put this article together describing one way of building such a testing environment.

State Department turned off spam filters for Hillary Clinton

Former Secretary of State Hillary Clinton’s emails, those sent from her private home server – using Clintonemail.com – were being caught in the spam filter, so the State Department turned the filters off.Bob Gourley, former CTO for the Defense Intelligence Agency (DIA) told Fox News, “You're putting not just the Clinton server at risk but the entire Department of State emails at risk. When you turn off your defensive mechanisms and you're connected to the Internet, you're almost laying out the welcome mat for anyone to intrude and attack and steal your secrets.”To read this article in full or to leave a comment, please click here

OpenSwitch Containers ♥ GNS3

OpenSwitchDocker

In one of my previous articles, I elaborated on a setup to create DC fabric simulations with GNS3 and OpenSwitch. I also promised to follow up with some post about using Ansible with it.

Well, I have been a bit distracted with some changes to the setup before moving into the Ansible details (to say true, I got the Ansible article almost ready, but things are moving so fast, that I keep rewriting it).

One of the things that ‘change everything’ recently was the release of GNS3 1.5. This is a great release that includes several features that makes using OpenSwitch with GNS3 awesome:

  • Support for Docker containers! This enables OpenSwitch to be a container instead of a VM, allowing to scale better:
    • This obviously consumes less RAM memory and use it more efficiently.
    • We are no longer limited to 8 ports per node (VirtualBox’s restriction), but instead we can have as many ports as you want. Even more, the OpenSwitch Appliance container will change the number of ports available, based on the GNS3 configuration.
  • Support for portable projects! Now you can export your project and shared it with others (restrictions apply).

Let’s see how to use this Continue reading

DNS Privacy

It seems that it's the season to consider "openess" in Internet Governance circles. The OECD has recently stated that: “the level of Internet openness will also affect the digital economy’s potential." And according to the Global Commission on Internet Governance (GCIG) “One Internet” report, an open and accessible Internet should generate several trillions of dollars a year in economic benefits. A fragmented Internet on the other hand would weigh on investment, trade and GDP, as well as on the right to free expression and access to knowledge.” It seems that the stakes are high when we consider Internet Openness. How well are we doing?

Amazing analysis of the Brexit with machine learning

So the UK has just given itself a national headache. Whether you think the Brexit was the right decision or a dangerous and unmitigated screw-up (as I do), the consequences of the referendum will be non-trivial and take years to complete. But the mechanics of the UK exiting the European Union aside, the question of how people now feel about the Brexit is interesting. Are they awash in jubilation or has buyer’s remorse set in? An intriguing post by MonkeyLearn attempts to answer this question by analyzing tweets and, as a bonus, provides tools that you might well find useful for similar exercises.First, let me explain what MonkeyLearn is: The service defines itself as a “[highly] scalable Machine Learning API to automate text classification.” To use MonkeyLearn you assemble your text data,  train and test a machine learning model with that data, then, using a custom API for your model, have your application code interact with the API to perform analysis and classification of new data. You can also provide your data to MonkeyLearn by pasting it into their Web interface or uploading CSV files or Excel spreadsheets.To read this article in full or to leave a Continue reading

Here’s how NASCAR is digitizing race day

When cars leave the starting line at Sonoma Raceway in California on Sunday for the start of the Toyota/Save Mart 350, they'll be taking part in the launch of a product designed to help NASCAR officials monitor and manage the 110-lap race.New race management software that NASCAR is launching on Sunday is designed to give officials a single screen to watch where cars are on the racetrack, manage penalties and share information with racing teams about what's going on.It arose from a partnership between NASCAR and Microsoft that started in 2014. It began with a mobile inspection app that let race officials see whether cars were in compliance with all the rules about how they have to be constructed.To read this article in full or to leave a comment, please click here

Should Microsoft release a successor to Surface 3?

Microsoft will stop manufacturing Surface 3 by the end of the year, which raises a big question: Will there be a Surface 4?The company has declined to say whether a Surface 4 will ever be released. But Microsoft says it saw strong demand for the Surface 3 tablet PC, so releasing a successor seems like a no-brainer.But the PC market is challenged. Upgrades have slowed down to every five or six years, and tablet shipments -- with the exception of 2-in-1s -- are declining. PC makers are already releasing innovative products that could be viable options to a Surface 3 successor.To read this article in full or to leave a comment, please click here

Worth Reading: Net Neutrality set in stone

Nothing is forever and beyond change. That said, it is beginning look as if net neutrality will be with us for a while. Certainly, it is embedded in our laws more firmly than it ever has been. In a 2-to-1 ruling, the U.S. Court of Appeals for the D.C. Circuit found that the rules promulgated early last year by the Federal Communications Commission (FCC) are legal. The challenge had been brought by a group of telecommunications companies and associations. The Washington Post reports that the ruling has the narrow impact of prohibiting unequal treatment of content providers. That, however, is just one example of the impact of a regulatory structure that enables telecommunications to be managed as a utility… -IT Business Edge

Researchers steal data from a PC by controllng the noise from the fans

Even the noise from your PC’s fans could be used to steal the data inside. Researchers in Israel have found a way to do just by hijacking the fans inside and manipulating the sounds they create.The research from Ben-Gurion University of the Negev shows how data could be stolen from “air-gapped” computers, which are not connected to the Internet.These air-gapped computers are isolated and typically contain the most sensitive information. To hack them, attackers typically need to gain physical access and install malware, possibly through a USB stick. To read this article in full or to leave a comment, please click here

The ‘summer of AI’ is here, this startup chief says

Artificial intelligence is still surrounded by an aura of mystery, and it would be tough to find a better illustration than the story in the news last week about a British grandmother who includes "please" and "thank you" in all her Google searches."Please translate these roman numerals mcmxcviii thank you," read the search request from May Ashworth that ultimately went viral when her grandson tweeted it on Twitter."I thought, well somebody's put it in, so you're thanking them," Ashworth reportedly explained. "I don't know how it works, to be honest. It's all a mystery to me."To read this article in full or to leave a comment, please click here
