Why is Apple avoiding wireless charging?

First, the iPhone 6 arrived last year without it. Now, comes the Apple Watch. Same story. Wireless charging seems to be something Apple's going to wait on even as major mobile manufacturers adopt it.Last week, Samsung announced that its Galaxy 6 and S6 Edge smartphones will have wireless charging. Two years ago, the Windows Phone 8-based Lumia 920 smartphone had wireless charging. So it's not as if it's not becoming a more mainstream technology.To read this article in full or to leave a comment, please click here

What caused the Google service interruption?

This morning people on twitter reported that they were unable to reach Google services. Businessinsider followed up with a story in which they mentioned that the Google service interruption primarily involved European and Indian users.

In this blog we’ll take a quick look at what exactly happened by looking at our BGP data. The first clue comes from David Roy and Franck Klopfenstein ‏on twitter who noticed traffic was re-routed towards AS9498 in India. Digging through our BGP data we are able to indeed confirm that routing paths for many google prefixes changed to a path that includes the Indian AS 9498 between 08:58 UTC and 09:14 UTC.

Let’s take a look at an example. In my case www.google.com resolves to the following addresses:
www.google.com has address 74.125.226.19
www.google.com has address 74.125.226.20
www.google.com has address 74.125.226.17
www.google.com has address 74.125.226.16
www.google.com has address 74.125.226.18
www.google.com has IPv6 address 2607:f8b0:4006:806::1014

The IPv4 addresses are all in the 74.125.226.0/24 range. If we now look at the BGP announcements for that Continue reading

10 common Android annoyances, solved

When you stop and think about it, smartphones are a lot like cars: They're fun, they're functional, and we always feel lost without them.

From insufficient storage and wonky auto-brightness to less-than-stellar stamina, certain problems seem to pop up often. And nine times out of 10, there's a pretty easy fix -- or at least some steps that can help make things a little bit better.To read this article in full or to leave a comment, please click here

12 early Apple Watch apps for business

Apple Watch Apps for BusinessImage by Apple/Shutterstock On March 9, Apple at last revealed more specifics about the much-anticipated Apple Watch. CEO Tim Cook said that following the release of the company's WatchKit SDK in November, developers created "thousands of new apps," a few of which were showed off by Apple vice president of technology Kevin Lynch. (You can jump to the 68-minute mark of the presentation video to see Lynch demo Watch apps.) Apple also revealed the new Apple Watch software, which is part of iOS 8.2 (now available) and lets you browse, buy and download apps for the watch.To read this article in full or to leave a comment, please click here

High-end phones on the way with LG, Huawei next in lineIf you were disappointed with the shortage of new flagship smartphones at Mobile World Congress last week, just hang on until next month. LG Electronics is expected to announce the highly anticipated successor to its good-looking G3—the G4?—that may sport a 1620 x 2880 pixel display. Huawei has started to post teasers for an event on April 8 for its P8, likely to offer a screen that’s a bit larger than the Ascend P7’s 5 inches, better battery life and an improved camera. Even Sony, which badly needs a big hit, may jump in the fray, with the Xperia Z4.To read this article in full or to leave a comment, please click here

Juniper rewires the data center

Juniper Networks this week rolled out new data center switches to help customers address opportunities and challenges presented by cloud computing.The new switches are yet another line of data center spine switches that have virtually no integration with Juniper’s three-and-a-half year old QFabric portfolio.Juniper says there will be 7.6 billion Internet users with 50 billion connected devices by 2020, continually accessing data around the globe. This necessitates higher levels of network performance, automation and scale for both enterprises and service providers to address growing demands on their IT infrastructure.+ MORE ON NETWORK WORLD: Juniper unveils new fabric switch, architecture +To read this article in full or to leave a comment, please click here

Reducing BGP SNMP Traps in DMVPN Networks

One of my readers decided to build a large DMVPN network with BGP as the WAN routing protocol (good choice!) and configured BGP SNMP traps with snmp-server enable traps bgp command on the hub router to detect spoke router failures. Turns out that’s not exactly a good idea.

Networks! Now, With More DevOps!

TL;DR - buzzwords suck and I want to rant about that.

I’ve been doing a lot of posts lately on the skillsets and technologies needed to move networking into the same level of productivity that other disciplines have reached. During this process, I’ve had time to contemplate labels and buzzwords.

By itself, I don’t see much value in the term “DevOps”, whether it’s succeeded by the phrase “for networking” or not. These days, the person using this term might just mean “automation”, or be describing a technical position.

As in “We’re looking for an experienced DevOp.” I know, right?

Just today I heard yet another story that illustrated a total misuse of this term, undoubtedly confusing all involved. I say, what’s in a name?

DevOps For Networks

This leads me down the path of considering that the phrase “DevOps for networking” is just as useless. Although I’m sure this was certainly not intended, this phrase implies that there is a special sector of the DevOps movement that is specific to networking. Unless you’re focusing on specific tools (which you shouldn’t be) then this isn’t the case. The underlying business value is precisely the same.

The DevOps culture and tooling that came Continue reading

Introducing New VCE VxBlock Systems with Integrated VMware NSX

Last month, we outlined VMware’s vision for helping customers achieve one cloud for any application and any device. We believe the prevailing

The EMC Federation

model for cloud adoption will be the hybrid cloud, and the best architecture for achieving the hybrid cloud is through a software-defined data center architecture.

The fastest path to building reliable infrastructure for the hybrid cloud is through the use of converged infrastructure systems, and no company has been more successful at delivering on the promise of converged infrastructure than our partner VCE.

Now, the ability to procure and deploy the VMware NSX network virtualization platform with VCE converged infrastructure is about to get whole lot easier.

Today, VCE launched VCE VxBlock Systems, a new family of converged infrastructure systems that will factory-integrate VMware NSX for software-defined data center deployments. The new VxBlock Systems will include VCE pre-integration, pre-testing and pre-validation of VMware NSX, with seamless component-level updates, ongoing lifecycle assurance, and unified single-call support from VCE.

As I wrote previously, VMware NSX already runs great on existing Vblock Systems. Customers today are deploying VMware NSX with their existing Vblocks, and customers will be able to extend VMware NSX environments across their entire Continue reading

Google researchers hack computers using DRAM electrical leaks

Google researchers have written the first-ever attack code that takes advantage of electrical interference between densely packed memory cells, a unique style of attack that could require changes in chip design.The work builds on a paper published last year by Carnegie Mellon University and Intel, which found it was possible to change binary values in stored memory by repeatedly accessing nearby memory cells, a process called “bit flipping.”DRAM memory is vulnerable to such electrical interference because the cells are so closely packed together, a result of engineers increasing a chip’s memory capacity.To read this article in full or to leave a comment, please click here

Twitter bans stolen nude photos and revenge porn

Twitter has amended its policies to ban the posting of intimate photos and videos taken without the person’s permission.“You may not post intimate photos or videos that were taken or distributed without the subject’s consent,” the company added to its rules on Wednesday.

What the *, traceroute?

If you've ever done a traceroute from one IOS box to another, you've undoubtedly seen output like this:

R8# traceroute 192.168.100.7
Tracing the route to 192.168.100.7
VRF info: (vrf in name/id, vrf out name/id)
  1 192.168.0.1 4 msec 3 msec 4 msec
  2 192.168.100.7 4 msec *  0 msec

That msec * msec output. Why is the middle packet always lost?? And why only on the last hop??
