SDN/OpenFlow/NFV Workshop: Frequent Questions

One of the potential attendees of my SDN workshop sent me a long list of questions. Almost every networking engineer, team leader or CIO asks the first one:

What will happen, if we don´t follow the SDN hype (in the short term, in the medium term and in the long term)?

Answering this question is the whole idea of the workshop.

The up-to-date list of scheduled SDN workshops is available on my web site.

Free SSL/TLS certificate project moves closer to launch

Let’s Encrypt, a project aimed at increasing the use of encryption across websites by issuing free digital certificates, is planning to issue the first ones next month.Digital certificates are used to encrypt data traffic between a computer and a server using SSL/TLS (Secure Sockets Layer/Transport Layer Security) and for checking that a website isn’t a spoof.Let’s Encrypt is run by the Internet Security Research Group (ISRG), a new California public-benefit corporation. Its backers include Mozilla, the Electronic Frontier Foundation, Cisco and Akamai.The first certificates will not be valid unless administrators install the organization’s root certificate in their client software, wrote Josh Aas, ISRG’s executive director, in a blog post.To read this article in full or to leave a comment, please click here

HTC move to test ads on BlinkFeed app angers users

As HTC faces shrinking revenue, the smartphone vendor is testing ads over its BlinkFeed media aggregation app, and some users aren’t happy.On Tuesday, HTC said it had begun rolling out an update to its BlinkFeed app that would include advertisements for users in the U.S., the U.K., China and a few other markets.The ads, for now, will be in a limited number, and promote sponsored apps, in addition to HTC accessories and devices, the company said in a blog post.“Because these are native ads, they will appear like a typical BlinkFeed post rather than as a pop-up or banner ad,” HTC added. However, users will be given an option to opt out from seeing the ads.To read this article in full or to leave a comment, please click here

How a bad keystroke can lead you to SpeedUpKit ‘scareware’

Dozens of misspelled domain names that spoof major brands are leading unsuspecting PC users to a questionable tune-up application called SpeedUpKit.Since people are unlikely to seek out the application, its promoters rely partly on people misspelling the domain name for prominent brands to lead them to it. If you try to access the obituary website legacy.com from a Windows PC in the U.S., for instance, but type “legady” by accident, you’re likely to end up on a page promoting SpeedUpKit.The practice, known as typosquatting, can sometimes violate consumer protection laws or constitute trademark infringement. Big brands police the web for such misspellings, and domain name registrars often try to stop the practice, but it still happens.To read this article in full or to leave a comment, please click here

HTIRW: That Big Number Database in the Sky

As we come close to ending this rather long running series on how the Internet really works (because I’m certain you’re about bored of this series, and ready for me to talk about something else!), I’d like to discuss three more topics I think are really important to the Internet’s operation on a day to […]

Can GitHub really be worth $2 billion?

If youre looking to hire a developer, which is more important: her LinkedIn profile or samples of her code on GitHub?Many would argue the latter, which helps to explain why the online code repository is reportedly closing in on a valuation of $2 billion.“GitHub is an interesting company,” said analyst Frank Scavo, president of Computer Economics. “It is partly a hosting service for developers and partly a social media site.”The San Francisco startup, which offers a popular code-sharing platform for software developers, is seeking a whopping $200 million in an upcoming private funding round that values the company as high as $2 billion, according to a report Monday from Bloomberg, which cited people familiar with the matter.To read this article in full or to leave a comment, please click here

Because dossiers

Here's the thing about computers -- even your laptop can support "big-data" applications. There are only 300-million people in the united states. At  1-kilobyte per person, that's still only 300-gigabytes -- which fits on my laptop hard-drive.

Building dossiers is becoming a thing in the hacking underground. Every time they break into a retail chain, hospital, insurance company, or government agency, they correlate everything back to the same dossier, based on such things as social security numbers, credit card numbers, email addresses, and even IP addresses. Beyond hacked secrets, public sources of information are likewise scanned in order to add to the dossier. Tools such as Maltego make it surprisingly easy to combine your own private information with public sources in order to build such dossiers.

When even the small hacking groups are focused on this effort, you can bet the big guys like China and Russia are even more interested in this.

This is one explanation behind the OPM hack. The hackers may have had something specific in mind, such as getting the personal information from SF86 forms where those seeking clearance are forced to disclose their various addictions and perversions. It may be used to blackmail people -- Continue reading

Wi-Fi and LTE join up for gigabit mobile service in Korea

What happens if you combine the best of Wi-Fi and cellular networks? In South Korea, consumers get gigabit-speed service to their phones.Samsung Electronics and mobile operator KT have developed a hybrid technology called GiGA LTE that can bring LTE and Wi-Fi signals together for download speeds as high as 1.17Gbps (bits per second), according to The Korea Herald. GiGA LTE is available now with a firmware upgrade to Samsung Galaxy S6 and S6 Edge handsets.Wi-Fi and LTE are becoming wary neighbors as cellular operators look for more spectrum and all types of wireless networks face growing user demands. Carriers are looking into LTE-Unlicensed, which can transmit LTE signals in the same band with Wi-Fi, and Qualcomm is now exploring a technology that would let more types of operators set up those networks. Some Wi-Fi backers say LTE-Unlicensed could squeeze out wireless LAN users.To read this article in full or to leave a comment, please click here

Twitter adds autoplaying videos

Twitter has moved well beyond its foundation of 140-character messages. The site will now host videos that play automatically in users’ feeds.Advertisers’ videos and those uploaded to Twitter natively, for example through its new video recording tool, will play automatically on the company’s desktop site and in its iOS app, with Android functionality coming soon, the company said Tuesday.The changes also apply to videos recorded with Twitter’s Vine app, and GIFs.Autoplaying videos, though possibly annoying, will help Twitter compete against Facebook, which started placing autoplaying videos, including those from advertisers, in users’ feeds in 2013. Twitter makes the bulk of its money through advertising, and more Internet companies are looking to siphon video advertising dollars away from traditional TV.To read this article in full or to leave a comment, please click here

From doughnuts to Dressgate: How real-time marketing helps brands stay relevant

It would have been easy enough for Dunkin’ Donuts to dismiss the Internet phenomenon “Dressgate” as irrelevant to its brand. What, after all, could an online debate over optical illusions and the color of a dress possibly have to do with pastry and coffee?Turns out, plenty. In a shining example of real-time marketing done right, Dunkin’ Donuts quickly identified the viral trend and rapidly conceived and executed a relevant promotion to insert its brand into the conversation. On the morning of Feb. 27—just hours after the phenomenon erupted—the company tweeted an image of a black-and-blue frosted doughnut alongside a white-and-gold one. “Doesn’t matter if it’s blue/black or white/gold, they still taste delicious,” read the accompanying text.To read this article in full or to leave a comment, please click here
