IDG Contributor Network: Last-mile mobile optimization boosts app performance

News watchers might have noticed a bunch of hot air and chest pounding emanating from media nuts a few days ago.The reason: the end of civilization was nigh for traditionalists, because Facebook and the New York Times had made a deal for Times content to be wrapped into Facebook pages, rather than simply linked to.Big deal, you might say. Makes sense. Add venerable 1851-launched newspaper content to a 1.3 billion-user social network, and stir thoroughly.Well, it does make sense. However, intriguingly, there's more to it than a simple you-scratch-my-back media deal. What's most interesting about this move is the technical reason prompting it.To read this article in full or to leave a comment, please click here

Safari users in the UK can sue Google over alleged privacy violations

The U.K. Court of Appeal won’t block a privacy lawsuit that alleges Google tracked Safari users without authorization, so the three plaintiffs can continue their legal fight against the search company.“These claims raise serious issues which merit a trial. They concern what is alleged to have been the secret and blanket tracking and collation of information, often of an extremely private nature, as specified in the confidential schedules, about and associated with the claimants’ internet use, and the subsequent use of that information for about nine months,” reads the decision, released Friday. “The case relates to the anxiety and distress this intrusion upon autonomy has caused.”To read this article in full or to leave a comment, please click here

BlackBerry shocks with Q4 profit but CEO Chen can’t stop sales slide

BlackBerry surprised Wall Street by getting its bottom line back into the black in the fourth quarter, but sales shrunk significantly again, putting in question CEO John Chen’s assertion that the company’s turnaround is on track.BlackBerry is trying to become less dependent on hardware, counting instead on software such as the BES12 enterprise mobile management platform, which can be used to manage not only the company’s devices but also iOS, Android and Windows Phone smartphones.During the quarter, which ended Feb. 28, software revenue grew 24 percent on a sequential basis and 20 percent year-on-year to US$67 million, the company said Friday morning before the U.S. financial markets opened.To read this article in full or to leave a comment, please click here

Musing: HP Networking Futures after deals with Aruba & H3C

HP Networking will acquire Aruba and now it is selling 51% stake in H3C to a Chinese venture capital firm.  What could this mean for HP Networking customers ?  The sale of a controlling interest in H3C means that HP Networking has government support (blessing?) to sell products in China. The Chinese government has been […]

Go Go Gadget Networking Lab!

For the last few years, if you wanted to set up a virtual network environment (for testing purposes, or setting up a lab, etc), it was more or less a manual process of installing software like the CSR 1000v from an ISO or OVA. Rinse and repeat. If you were fortunate enough to work at a company with decent virtual machine automation and infrastructure (and had access to it) then you could in theory make this a little easier, but it’s hardly portable. However, this is still much better than it was only a few short years ago, when many vendors simply did not offer a virtual machine version of their routers and firewalls.

The other day I was catching up on some Twitter feed, and I noticed a tweet from John Deatherage that caught my eye:

I’ve been using Vagrant for about a year, so I’ve got a bit of experience with it, but mostly with server operating systems. Seeing this tweet reference it’s use in the context of spinning up instances of a Continue reading

Microsegmentation in VMware NSX on Software Gone Wild

VM NIC firewalls have been around for years (they’re also the reason I got my first invitation to the awesome Troopers conference), but it sounds so much better when you call them Microsegmentation (not the one I talked about @ Troopers this year).

Marketing gimmicks aside, VMware NSX includes an interesting in-kernel stateful firewall, and Brad Hedlund was kind enough to explain the intricacies of that feature in Episode 27 of Software Gone Wild

UN to appoint watchdog to focus on privacy in digital age

The Human Rights Council of the United Nations has voted in favor of a resolution backed by Germany and Brazil to appoint an independent watchdog or ‘special rapporteur’ to monitor privacy rights in the digital age.The council said Thursday that the same rights that people have offline must also be protected online, including the right to privacy.The proposed appointment of the rapporteur is likely to be mainly symbolic as the official’s functions will be mainly advisory. But it reflects continuing concerns around the world about privacy in the wake of disclosures of U.S. surveillance by former National Security Agency contractor, Edward Snowden.To read this article in full or to leave a comment, please click here

At Facebook, a sharpening focus on virtual reality

In 10 years, there may be no need to check Facebook’s site to see what that friend overseas is up to. You might just pick up a pair of goggles, reach out and hold her hand at her birthday party.You won’t have to actually be there. The experience could be made possible through virtual reality.Facebook sees it as a radical and important technology that in the not-too-distant future could provide new ways to help people connect and transport them to places that are out of reach or don’t even exist. Providing those experiences is among Facebook’s ambitious long-term goals, along with providing Internet access through aerial drones and deepening its artificial intelligence technology to better understand what people want.To read this article in full or to leave a comment, please click here
