Video And The Death Of Dialog

video

I was reading a trivia article the other day about the excellent movie Sex, Lies, & Videotape when a comment by the director, Stephen Soderbergh, caught my eye. The quote, from this article talks about how people use video as a way to distance ourselves from events. Soderbergh used it as a metaphor in a movie made in 1989. In today’s society, I think video is having this kind of impact on our careers and our discourse in a much bigger way.

Writing It Down In Pictures

People have become huge consumers of video. YouTube gets massive amounts of traffic. Devices have video recording capabilities built in. It’s not uncommon to see a GoPro camera attached to anything and everything and see people posting videos online of things that happen.

My son is a huge fan of videos about watching other people play video games. He’ll watch hours of video of someone playing a game and narrating the experience. When I tell him that he’s capable of playing the game himself he just tells me, “It’s not as fun that way Dad.” I, too, have noticed that a lot of things that would normally have been written down are Continue reading

How to set up a portable, non-cloud-based password manager

Nothing helps strong passwords become a central tenet of your electronic life than conscientious use of a password manager. However, the compromise of at least one cloud-based password manager last year and recent actions by a government agency may have given you second thoughts about using the cloud for something that instinctively feels like it should be managed locally.Those incidents aside, password managers remain the best way to avoid reusing weak passwords which is as commonplace as the number of password leaks that happen every year, even on large, reputable websites. And, if you don’t mind putting in a modicum of effort, you can still establish a non-cloud-based password manager that can be utilized across multiple devices.To read this article in full or to leave a comment, please click here

Expert: Comprehensive software security for cars will take years

Software security for automobiles is improving but it will take another three or four years until manufacturers can put overarching security architecture in place, says Stefan Savage, winner of the 2015 ACM-Infosys Foundation Award in the Computing Sciences.“We’re at a point where the industry has to recognize that this is a real issue for them,” says Savage, a professor in the Computer Science and Engineering department at the UC San Diego Jacobs School of Engineering.+ MORE CAR SECURITY: Car hackers urge you to patch your Chrysler, Ram, Durango, or Jeep +To read this article in full or to leave a comment, please click here

Cross-VC NSX for Multi-site Solutions

The Cross-VC NSX feature introduced in VMware NSX 6.2, allows for NSX logical networking and security support across multiple vCenters. Logical switches (LS), distributed logical routers (DLR) and distributed firewall (DFW) can now be deployed across multiple vCenter domains. These Cross-VC NSX objects are called Universal objects. The universal objects are similar to distributed logical switches, routers, and firewall except they have global or universal scope, meaning they can span multiple vCenter instances. With Cross-VC NSX functionality, in addition to the prior local-scope single vCenter objects, users can implement Universal Logical Switches (ULS), Universal Distributed Logical Routers (UDLR), and Universal DFW (UDFW) across a multi-vCenter environment that can be within a single data center site or across multiple data center sites. In this post we’ll take a look at how we do this. Continue reading

The Trouble with Tor

The Tor Project makes a browser that allows anyone to surf the Internet anonymously. Tor stands for "the Onion router" and that describes how the service works. Traffic is routed through a number of relays run across the Internet where each relay only knows the next hop (because each hop is enclosed in a cryptographic envelope), not the ultimate destination, until the traffic gets to the final exit node which connects to the website — like peeling the layers of an onion.

Think of it like a black box: traffic goes into the box, is bounced around between a random set of relays, and ultimately comes out to connect to the requested site. Anonymity is assured because anyone monitoring the network would have a difficult time tying the individuals making the requests going into the black box with the requests coming out.

Importance and Challenges of Anonymity

Anonymity online is important for a number of reasons we at CloudFlare believe in. For instance, Tor is instrumental in ensuring that individuals living in repressive regimes can access information that may otherwise be blocked or illegal. We this is so important that we offer Continue reading

Court vacates iPhone hack order against Apple, focus shifts to New York

A judge in California vacated on Tuesday an earlier order asking Apple to assist the FBI in cracking the passcode of an iPhone 5c running iOS 9 that was used by one of the San Bernardino terrorists.The focus of the dispute between Apple and the government over whether it can be compelled to help agencies access data on iPhones now shifts to a court in Brooklyn, New York, where Apple is contesting an order to extract data from the passcode-locked iPhone 5s of an alleged drug dealer.The FBI had requested the California court on Monday to vacate the order as the government had successfully accessed the data stored on the iPhone used by Syed Rizwan Farook and no longer required Apple’s assistance.To read this article in full or to leave a comment, please click here

CNBC just collected your password and shared it with marketers

CNBC inadvertently exposed peoples' passwords after it ran an article Tuesday that ironically was intended to promote secure password practices. The story was removed from CNBC's website shortly after it ran following a flurry of criticism from security experts. Vice's Motherboard posted a link to the archived version. Embedded within the story was a tool in which people could enter their passwords. The tool would then evaluate a password and estimate how long it would take to crack it. A note said the tool was for "entertainment and educational purposes" and would not store the passwords. That turned out not to be accurate, as well as having other problems.To read this article in full or to leave a comment, please click here

Next-Generation Network Telemetry

Late last year, I was pleased to be part of a special Tech Field Day event focused on network analytics. We had a day full of presentations from folks like Netflix, Google, and some goofball with a wrinkly jacket - all focused on what the next-generation networks will look like with respect to analytics. This was a while ago, but I’ve wanted to write about this ever since, and a recent conversation gave me the spark I needed.

Spousetivities at OpenStack Summit in Austin

Long-time readers know that my wife, Crystal, has been running this thing called Spousetivities for a few (OK, eight) years now. While Spousetivities originally started out as a VMworld thing, it rapidly expanded, and this year Spousetivities will be at a number of events. That includes the spring OpenStack Summit in Austin, TX!

If you’re planning to attend the Summit in Austin, why not bring your spouse/fiancé/partner/significant other with you? I can tell you from personal experience that having him or her there with you makes the conference experience more pleasant. In this particular case, Austin is a great place to visit in April and it is very affordable. Besides, Spousetivities has a great set of activities planned to keep your traveling companion(s) entertained while you’re at the conference.

Here’s a quick look at some of what’s planned for that week:

  • Explore Austin via a unique scavenger hunt experience, complete with prizes
  • Cruise the lake on private, luxury paddle-wheel boat while enjoying a delicious catered lunch
  • BBQ galore—after all, this is the BBQ capital and Spousetivities will make sure you get to try the famous BBQ of the Salt Lick
  • Quaint and relaxing tour of historic Fredericksburg

Microservices

First, I want to mention that - in no small part due to the Netflix presentation - this was one of the first times I’ve heard microservices brought up in a network tooling context. Sure, microservices are all the rage and we’ve definitely seen a lot of activity regarding how to bring our networks up to the level required by these new application architectures. However, starting with this event, I’ve also started to notice a tremendous value in approaching the network software itself with a microservices architecture, instead of the monolithic network monitoring/management software we use today.

More on that in a future post.
