Running an etcd 2.0 Cluster on Ubuntu 14.04

In this post, I’m going to show you how to set up a cluster of three nodes running etcd 2.0 (specifically, etcd 2.0.9). While I’ve discussed etcd before, that was in the context of using etcd with CoreOS Linux. In this case, I’ll use Ubuntu 14.04 as the base OS, along with the latest released version of etcd.

To help you follow along, I’ve created a set of files that will allow you to use Vagrant to turn up an etcd 2.0 cluster on Ubuntu 14.04 (on your laptop, if so desired). You can find all these files in the “etcd-2.0” directory of my learning-tools GitHub repository.

Installing the Base OS

You don’t need anything special when setting up etcd; a straightforward Ubuntu Server 14.04 x64 installation will work just fine. If you’re using the files in my learning-tools repository, you’ll see that Vagrant simply turns up a VM based on a plain-jane Ubuntu 14.04 box. If you’re building this from scratch (why?!), simply create a VM and install Ubuntu 14.04 into it. As long as it has Internet connectivity, that’s all that’s needed.

43% of Slashdotters call ISPs liars

I know what you’re thinking: Only 43%?But we’re talking here about a single question: “How do your actual ISP speeds compare to the advertised speed?”And as you can see from the screen capture of the poll results above, roughly four in 10 of some 5,000 Slashdotters who bothered to weigh in say their actual speeds are slightly lower or significantly lower than what their ISPs advertise.Yes it’s an online poll and hence a self-selected sample, but these are people who by and large care more and are better equipped to make this judgment than other ISP customers.To read this article in full or to leave a comment, please click here

Transition to IP network creates cybersecurity challenges for FAA

The Internet hasn’t totally invaded the nation’s air traffic control system, but as it does the Federal Aviation Administration faces a growing challenge to make sure the network is locked down secure.The security issues arise as the agency moves from a point-to-point legacy air traffic control structure to a new IP-based system commonly known as NextGen or Next Generation Air Transportation System. NextGen in a nutshell will move the current radar-based air traffic system to one that is based on satellite navigation and automation.+More on Network World: The most magnificent high-tech flying machines+To read this article in full or to leave a comment, please click here

Pure Storage CEO promises huge savings with flash

The term 'disruption' gets tossed about a lot -- too often -- in the technology industry. But it isn't always hype. Backed by nearly half a billion dollars in investment, CEO Scott Dietzen and Pure Storage are hard at work disrupting a big chunk of the enterprise storage market owned by the likes NetApp and EMC, which is no stranger to disruption itself, having turned the tables on a previous generation of storage leaders.I had the opportunity to talk to [EMC CEO] Joe Tucci a couple of months back and I asked him about flash. I'm paraphrasing him here, but he describes a world where there's a role for tape, disk, flash.

For Microsoft, hardware and OS consistency key in Surface 3

With the upcoming Surface 3, Microsoft is ending experimentation and bringing back hardware and OS consistency across its line of tablets, hoping that consumers and businesses will find a lot to like.The Surface 3 is radically different than its predecessor, Surface 2, which had an ARM processor and the tablet-specific Windows RT OS. The Surface 3 sports a full Windows 8.1 OS and an Intel x86 processor, which is the combination available in most PCs and laptop-tablet hybrids today.The Surface 3, which has a 10.8-inch screen, is a thinner and lighter version of Surface Pro 3 and can offer longer battery life, said Brian Eskridge, senior manager for Microsoft’s Surface products.To read this article in full or to leave a comment, please click here

Huawei’s P8 and P8max get all-metal designs, improved camera

Huawei Technologies is betting its all-metal P8 and the P8max will help the company make further inroads into the high end of the smartphone market.Following in the footsteps of the Galaxy S6 and S6 Edge from Samsung Electronics and the HTC One M9 is no easy feat, but Huawei is hoping it has developed a product that can compete with those devices.The P8 has a 5.2-inch, 1080-by-1920-pixel screen and is powered by a HiSilicon Kirin 64-bit processor with eight cores running at 1.5GHz or 2GHz. It has 16GB or 64GB of integrated storage and 3GB of RAM. The integrated storage can be expanded using a microSD card.Huawei has also worked to make the P8 look more premium.

Six net neutrality lawsuits: What are the complaints about?

One of the main arguments for the trade groups and ISPs that have filed six—yes, six—lawsuits against the U.S. Federal Communications Commission’s net neutrality rules is that the agency violated a 69-year-old administrative procedure law in crafting the new regulations.The two ISPs and four trade groups filing lawsuits in recent days have challenged the FCC’s decision—as part of the new net neutrality rules—to reclassify broadband as a regulated, common-carrier service, instead of its long-standing classification of broadband as a lightly regulated information service. The plaintiffs, in addition to accusing the FCC of violating administrative procedure, will argue the agency violated ISPs’ constitutional rights.To read this article in full or to leave a comment, please click here

Don’t look now, but ATMs are about to get a cloud makeover

Automated teller machines have been around for decades, but surprisingly few changes have been made to the technologies that run them. That’s about to change.NCR on Wednesday rolled out new software that will transform ATMs to use the cloud with Android and a thin-client model of computing. The result, it says, will be a big boost in security as well as dramatically lower costs.Most of the world’s 2.2 million or so ATMs today are essentially thick-client PCs, and the vast majority of them—as much as 75 percent—run Windows XP, NCR says. It’s perhaps no wonder that security is an issue, yet banks typically must still administer updates manually to each ATM in their network.To read this article in full or to leave a comment, please click here

Apple buys Israeli camera technology company

Apple has purchased LinX Imaging, an Israeli company that makes multi-lens cameras for smartphones, tablets and ultrabooks.A distinguishing feature of LinX’s cameras are their small size. Its cameras “are nearly half the height of a standard mobile camera,” according to a news release from 2014 discussing the company’s latest imaging technology. LinX’s cameras can capture images that rival the quality of pictures taken with high-end SLR cameras, the release said.Smaller components could help Apple since the company is known for slimming down its hardware. For example, Apple’s new MacBook replaces the traditional USB Type-B ports and power jack with a single USB Type-C port to cut down on size.To read this article in full or to leave a comment, please click here

IDG Contributor Network: How smartphone sensors can make expensive weather-monitoring equipment obsolete

Currently, millions of drivers are traveling around our cities collecting data on road traffic with their smartphones. The objective: crowd-sourced traffic conditions.Drivers simply install an app onto their smartphones. The device collects data, and then the system shares the nuances of traffic jams with other app users for the "common good," as Google's Waze, the app's developer, describes it.Waze and the GPS sensor In that case, speed and location is calculated by the smartphone's GPS sensor. Waze has somewhere between 20 and 50 million users, depending on who you listen to.To read this article in full or to leave a comment, please click here
