Video: How waterproof is the Apple Watch?

Ever since the Apple Watch was unveiled back in September, there's been a lot of discussion surrounding how the device might withstand water. In the months leading up to the actual Apple Watch release, there were a few reports indicating that the device was not waterproof, but rather water-resistant. Which is to say, getting a few splashes of water on the device won't ruin it, but it's not something you'd want to go swimming with.Now that the Apple Watch is on store shelves, or available for pre-order to be more exact, the inevitable wave of amateur Apple Watch durability testing has begun. And, as luck would have it, Apple Watch users will be glad to know that their new wearable is much more water-friendly than most initially assumed.To read this article in full or to leave a comment, please click here

What is a non-blocking switch?

How does Internet work - We know what is networking

It is fairly common to hear about switch being non-blocking. It’s because almost all switches today are non-blocking. But what that means? When I asked people around me on what exactly non-blocking switch means, they were unable to get to the same conclusion. I was going through a lot of different internet places and vendor documents before I wrote this here, but, do not hesitate to add something in comments if you have different view on the subject. Line-rate switch means the same as if you would said wire-speed switch. It basically means that this switch has the forwarding capacity that supports concurrently

New Magento WAF Rule – RCE Vulnerability Protection

Today the Magento Security Team created a new ModSecurity rule and added it to our WAF rules to mitigate an important RCE (remote code execution) vulnerability in the Magento web e-commerce platform. Any customer using the WAF needs to click the ON button next to the “CloudFlare Magento” Group in the WAF Settings to enable protection immediately.

CloudFlare Magento Rule

Both Magento version 1.9.1.0 CE and 1.14.1.0 EE are compromised by this vulnerability. CloudFlare WAF protection can help mitigate vulnerabilities like this, but it is vital that Magento users patch Magento immediately. Select and download the patch for SUPEE-5344.

Starbucks hit by major computer failure

Starbucks suffered what appears to be a major computer system failure late Friday.Stores in Boston, New York, San Diego and other cities appeared to be affected, judging from hundreds of customer and employee posts on Twitter. Some stores are giving away drinks, are only accepting cash, or have closed, according to the messages.In San Francisco, an employee at one store said they were giving away free drinks, though he did not offer many other details. He said he was not sure when service would be restored.Starbucks did not immediately respond to telephone calls and emails requesting comment.To read this article in full or to leave a comment, please click here

Running vSphere on AWS or GCE

By now you’ve probably seen or heard the news about Ravello Systems launching Inception—the ability to run nested VMware ESXi on AWS or GCE, including the ability to run VMs on these nested ESXi instances. (Here’s Ravello’s press release.)

In my opinion, this is pretty cool, and it opens the door to a lot of different possibilities: upgrade testing, automation testing, new feature testing, hosted home labs (aka “Lab as a Service”). Lots of folks are interested in using this new Ravello functionality for “Lab as a Service.” Here’s Andrea Mauro’s take on this topic.

As part of the pre-launch activities, a number of bloggers and community advocates were able to work with Ravello on some very interesting projects:

  • William Lam built both a 32-node VSAN cluster (running vSphere 5.5) as well as a 64-node VSAN cluster (running vSphere 6.0). He posted details here, along with a great walkthrough of setting up vSphere on Ravello.
  • Mike Preston built out an environment that allowed him to perform a vMotion from AWS to GCE.

I was also engaged with Ravello on a project: building a (reasonably) large-scale vSphere environment on Ravello. The original goal was to Continue reading

Kubernetes and OpenContrail

I’ve been working over the last couple of weeks in integrating OpenContrail as a networking implementation for Kubernetes and got to the point where i ‘ve a prototype working with a multi-tier application example.

Kubernetes provides 3 basic constructs used in deploying applications:

  • Pod
  • Replication Controller
  • Service

A Pod is a container environment that can execute one or more applications; each Pod executes on a host as one (typically) or more Docker processes sharing the same environment  (including networking). A Replication Controller (RC) is a collection of Pods with the same execution characteristics. RCs ensure that the specified number of replicas are executing for a given Pod template.

Services are collections of Pods that are consumable as a service. Through a single IP end point, typically load-balanced to multiple backends.

Kubernetes comes with several application deployment examples. For the purpose of prototyping, I decided to use the K8PetStore example. It creates a 4-tier example: load-generator, frontend, redis-master and redis-slave. Each of these tiers, except for the redis-master) can be deployed as multiple instances.

With OpenContrail, we decided to create a new daemon that listens to the kubernetes API using the kubernetes controller framework. This daemon creates virtual networks on demand, for each Continue reading

Teardown of Apple Watch shows sensor could measure blood oxygen levels

The Apple Watch's sensor may hold more health monitoring functions than Apple has revealed, including measuring blood oxygen levels, a feature that's not enabled on the device and that Apple hasn't talked about.That's one of the findings from iFixIt, which disassembled an Apple Watch Sport Edition on the day the wearables started shipping to customers.U.S. government regulations may prevent Apple from allowing the watch to capture blood oxygen data, according to iFixIt, whose website lets people offer each other advice on how to fix a variety of things, including computer hardware. The site is also known for breaking apart Apple's new products as soon as they go on sale.To read this article in full or to leave a comment, please click here

PlexxiPulse—Breaking Down the Distributed Network

Most networks today (including Plexxi solutions) are built as distributed networks. This type of infrastructure reduces complexity and significantly increases network capabilities. Our own Marten Terpstra took a deep dive into the future of distributed networks this week on the Plexxi blog. He identifies and breaks down the “central command” system of today’s distributed networks, and its impact on the functionality of network solutions as a whole. Give it a read before you head out for the weekend.

Below please find a few of our top picks for our favorite news articles of the week. Have a great weekend!

CIO: Declare Your Independence – Virtualize that Network!
By Paul Gillan
Although a relative newcomer to virtualization compared to its server and storage brethren, virtualized networks – and their companion, software-defined networking (SDN) technology – are a no-brainer for any company that’s virtualizing other parts of its IT infrastructure. Once you move platforms to an internal cloud, you’ll want the underlying transport layer to deliver the same flexibility as the virtual resource. Storage, servers, desktops and software all benefit from a more flexible network.
