A surge of Pokemon Go-related apps is out to steal your data

Privacy fears about the Pokemon Go app have been largely addressed, but dozens of other apps that piggy back on the popular game have raised further concerns.Since the game launched last week, a swarm of unofficial apps has emerged and is trying to capitalize on the title’s success. And many are hungry for your personal data.These unofficial apps have been offering cheats, tips and even songs from the hit game. But in exchange, they demand permission to access sensitive data on your phone, said Chad Salisbury, a security engineer with RiskIQ, which monitors mobile malware.To read this article in full or to leave a comment, please click here

BRKRST-2042 – Highly Available Wide Area Network Design

Presented by: David Prall, Communications Architect, Cisco

For reference, David is the “father of IWAN”.

This session was not what I was expecting. I was expecting design and architecture, but it was all about features in IOS and IOS-XE (eg, FHRPs, talked about routing protocol timers, PfRv3, BFD). I guess I need to pay more attention to the session code (RST == routing; ARC == architecture).

IBM and AT&T are cozying up to IoT developers

Big IoT partnerships are coming thick and fast these days. A deal between IBM and AT&T to help developers turn IoT ideas into reality is just the latest tie-up involving major enterprise vendors in this field.The partnership will combine AT&T’s connectivity with IBM’s Watson and Bluemix analytics platforms. Through APIs (application programming interfaces) and development environments, plus open-source tools, the two companies say they’ll make life easier for developers.IoT involves so many parts that it’s almost inevitable enterprises will be working with several vendors to get their infrastructure up and running. Devices that collect data, clouds that analyze it, and networks that link the two are just the main components of systems that can rival the complexity of anything in IT.To read this article in full or to leave a comment, please click here

BRKEWN-2017 – Understanding RF Fundamentals and the Radio Design of 11n/ac Networks


Presenter: Fred Niehaus, Technical Marketing Engineer, Cisco Wireless Networking Group

Basic understanding of radio:

  • Every radio wave has a physical size (proportionate to its wavelength)
  • The lower the frequency, the physically longer the radio wave
  • Higher frequencies have shorter waves and as such, takes more power to move them greater distances
  • 5Ghz UNI 2 and UNI 2 Ext overlap with DFS (RADAR)
  • Dynamic Freq Selection (DFS) requires that if a radio is operating in UNI 2/UNI 2 Ext and it hears something that is not WiFi, it has to get off that channel

Antenna basics:

  • Directional or omnidirectional (360 degree)
  • Cisco color markings: blue: 5, black 2.4, orange 2.4 and 5ghz
  • Low gain omnidirectional antennas radiate in a beach ball pattern
  • Omni-direction dipoles in a pancake pattern
  • Yagis are directional; radiate more like a flashlight
  • Patch: multiple elements in a square form factor; radiates like a flashlight
  • Dipole: does not require a ground plane as the bottom half is the ground
  • Monopole requires a (conductive surface) ground plate; monopoles are shorter than dipoles and often used on APs (because of the smaller size) and they can use the metal in the AP as the ground plate.
  • Azimuth: how Continue reading

iPhone 7 to have nearly 15% bigger battery than the iPhone 6s

Noted iPhone leaker OnLeaks (aka Steve Hemmerstoffer of Nowhereelse.fr) published an interesting tweet earlier today indicating that the iPhone 7 may finally address one of the more longstanding complaints about Apple's iconic smartphone: battery life. To be clear, Apple has made tremendous improvements in the iPhone's battery technology over the years, but as we continue to demand more and more from our smartphones, many people find that they can't even go a full day on their iPhone with a single charge.That being the case, OnLeaks's tweet relays that the iPhone 7's battery will have nearly 15% more capacity than the iPhone 6s battery. Pretty reliable (not 100% but almost...) source told me #iPhone7 battery = 1960mAh (#iPhone6s = 1715mAh)To read this article in full or to leave a comment, please click here

Slideshow: Inside Facebook’s lab where it tests 2,000 phones at once

Facebook can test its code on 2,000 phones at onceImage by FacebookFacebook makes thousands of changes in its code every week. Any one of them could accidentally cause Facebook software to take up more data, memory or battery life on your phone. So the company tests code on more than 2,000 phones to account for different hardware models, operating systems and network connections.To read this article in full or to leave a comment, please click here

Microsoft spices up Surface Hub with Azure cloud services

Microsoft's supersize Surface Hub is often viewed as a computer for videoconferencing and digital whiteboarding, but it is emerging as more than just the centerpiece of a conference room.The Surface Hub is a one-of-a-kind, all-in-one PC with a 55- or 84-inch screen that started shipping a few months back. The device provides new ways for users to present, exchange, share and manipulate data from the Azure cloud, said Hayete Gallot, general manager at Microsoft Devices.Users are still exploring ways in which it can be used. The large screen and collaborative features can be powerful tools in visualizing data extracted from the cloud, Gallot suggests.To read this article in full or to leave a comment, please click here
