Huawei looks to give indoor mobile speeds a boost with LTE-Advanced

Huawei Technologies has conducted a real-world trial of LTE-Advanced that shows that much faster indoor cellular speeds may be around the corner.The telecommunications equipment vendor conducted the trial with Singaporean network operator StarHub, using products capable of download speeds of up to 300Mbps. Early test results were promising, with users getting much faster downloads and better video quality than before, Huawei said without offering any details of the data rates achieved.The speed increase is fueled by a technique called carrier aggregation, an LTE-Advanced technology that allows mobile operators to treat up to three radio channels in different frequency bands as if they were one.To read this article in full or to leave a comment, please click here

Talented startup aims to deliver software defined cloud

One of the ways you can tell that software defined networking (SDN) has the power to change the vendor landscape is by the number of startups that have emerged. Over the past few years, we've seen startups pop up to address the evolution of the data center and the WAN. For this reason, I always tend to keep my eyes open for companies generating buzz in the marketplace in this area. In my recent travels, I was made aware of another "stealth-mode" startup that's building a solution to address a new use case for SDNs. According to its website, Avni Networks addresses the "transformation of the Data Center to Virtual Clouds for the Applications Economy." From what I can tell, there seems to be some buzz around what this company is up to, which made me curious about learning more.To read this article in full or to leave a comment, please click here

5 cool ways to give an iOS device a physical keyboard

This week, a startup named Tactus Technology got a lot of attention for its Phorm iPad Mini case, which includes a transparent screen cover that creates bubbles over each letter in the iOS keyboard. It's basically a tactile keyboard that appears on a touchscreen only when the user needs it. Tactus has been working on its on-demand keyboard technology for more than five years, according to Wired. The screen cover is based on microfluidic technology, which has its roots in ink jet printers, and it has small grooves carved into the spot where each letter appears on the iPad screen. When the user slides a switch on the back of the case – which appears to be almost a third of the size of the rear of the case, so it won't require you to flip your iPad around and hunt for a button – the case applies a small amount of pressure that forces a tiny amount fluid to rush across the screen. That fluid gets caught fills up each of the grooves, creating bubbles that act as tactile buttons on the touchscreen keyboard. Here's a video showing the technology in use.To read this article in full or Continue reading

Information disclosure flaw exposes Netgear wireless routers to attacks

Several wireless routers made by Netgear contain a vulnerability that allows unauthenticated attackers to extract sensitive information from the devices, including their administrator passwords and wireless network keys.The vulnerability can be exploited over local area networks, as well as over the Internet if the devices are configured for remote administration and expose their Web interface externally.Details about the vulnerability were published on the Full Disclosure mailing list last week, along with a proof-of-concept exploit. Peter Adkins, the researcher who found the flaw, claims that he contacted Netgear but that his attempts to explain the nature of the issue to the company’s technical support department failed.To read this article in full or to leave a comment, please click here

Myths That Refuse to Die: Scalability of Overlay Virtual Networking

If you watched the Network Field Day videos, you might have noticed an interesting (somewhat one-sided) argument I had with Sunay Tripathi, CTO and co-founder of Pluribus Networks (start watching at around 32:00 to get the context). Let’s try to get the record straight.

Is Apple building a car?

Early last week, a somewhat bizarre Apple rumor emerged from out of nowhere. Specifically, rumor has it that Apple is seriously investigating the prospect of developing its own branded automobile. The wave of rumors began a few days ago when Business Insider posted a report claiming that Apple was working on an exciting project that was luring back former employees from Tesla.... We got an unsolicited email from an employee at Apple about "vehicle development" at the company. This person said Tesla employees were "jumping ship" to work at Apple. "Apple's latest project is too exciting to pass up," the person said. "I think it will change the landscape and give Tesla a run for its money." Initially, it was easy to scoff at the report. Not only does the notion of Apple getting into the car business seem absurd on its face, but it's not as if Apple employees are exactly known for sending unsolicited emails about top secret research initiatives to tech publications. At most, the prevailing attitude was that Apple was simply keen on deepening their exploration into automotive-based software such as CarPlay. The very next day, Bryan Chaffin of Mac Observer chimed in with a Continue reading

Xiaomi leads China’s smartphone market, despite Apple’s iPhone 6

Apple’s iPhone 6 has been a hit in China, but according to one account, rival Xiaomi still reigns as the country’s largest smartphone vendor.In last year’s fourth quarter, Android handset maker Xiaomi had a 13.7 percent share, while second place Apple only had a 12.3 percent share, research firm IDC said Monday.The rankings are, however, different from those of another research firm Canalys, which put Apple as the top vendor, and Xiaomi second.Apple achieved in the fourth quarter its highest quarterly market share in China over the past two years, and it came from strong demand for its newest iPhone, said Xiaohan Tay, an IDC analyst.To read this article in full or to leave a comment, please click here

Infosys to acquire startup Panaya to automate customer tasks

Indian outsourcer Infosys is to acquire Panaya, a U.S. vendor of automation technology for testing enterprise software deployments and upgrades.The cash deal values Panaya at an enterprise value of US$200 million, and is in line with the company’s strategy under new CEO Vishal Sikka to automate processes, including by using artificial intelligence, to cut down on repetitive tasks and accelerate services delivery.“This acquisition aims to use automation to boost the revenue of the company without a corresponding increase in staff,” said Sudin Apte, CEO and research director at analyst firm Offshore Insights. He pointed out that Infosys’ rivals like Tata Consultancy Services already use some degree of automation developed in-house.To read this article in full or to leave a comment, please click here

Cybercriminal gang plunders up to $1 billion from banks over two years

A still-active cybercriminal gang has stolen up to a $1 billion from banks in at least 25 countries over the last two years, infiltrating networks with malware and spying on employees’ computers to facilitate large wire transfers, Kaspersky Lab said Sunday.The computer security vendor, which said it will release a report Monday on its findings, said the gang penetrated deeply into the banks’ networks, taking time to learn about internal procedures to make their fraudulent activity less suspicious.In some cases, the gang learned about wire transfer systems by watching administrators’ computers over video.“In this way the cybercriminals got to know every last detail of the bank clerks’ work and were able to mimic staff activity in order to transfer money and cash out,” Kaspersky said in a news release.To read this article in full or to leave a comment, please click here

Generating Web Docs for Ansible Modules

If you have ever worked with Ansible, it’s almost a guarantee that you have used their online docs to figure out what parameters a given module supports, how they should be used, or what their defaults are. Over the past few weeks, I’ve been working on a few custom modules and was trying to find a way to generate web docs for them, and have them locally accessible or easily posted to GitHub.

Ansible offers a way to “make webdocs,” but it generates the complete module inventory and truth be told, I didn’t get this work for my custom modules, so I figured I would explore a “simplified” way — a way that should be able to generate docs as needed for one or more modules on an as needed basis.

The outcome was the creation of an Ansible module and Jinja2 template that automatically generates a markdown file (that can then be viewed or posted anywhere).

How does it work?

The modules you’ve built or are local to your machine (even Ansible core modules) that you want to generate a web doc for must be documented according to Ansible standards. That’s the only major requirement.

From there, Continue reading

NAT, Security, and Repeating Myself
