IoT seems to be a hot
topic recently.
The
Tangled Web of IoT Security
… In addition to
there being no clear definition of the IoT, estimates vary widely
about the number of unique devices it includes. There are an
estimated 26 billion devices, according to Gartner,
but a whopping 212 billion, according to IDC.
… The Internet of
Things has
the potential to create an economic impact of US$2.7 trillion to
$6.2 trillion annually by 2025, Microsoft said, based on statistics
from McKinsey Global Institute.
As a result of the IoT,
"potentially billions of devices will
report data about themselves, making it possible to create new
applications in areas as diverse as factory optimization, car
maintenance, or simply keeping track of your stuff online,"
notes an MIT Technology Review report.
This may help. (I
should have written a book like this) $42 ($35 paperback) or read
the whole thing online for free.
New
Report Details Basics of Cybersecurity for Decision Makers
by Sabrina
I. Pacifici on May 6, 2014
“At
the Nexus of Cybersecurity and Public Policy offers a wealth of
information on practical measures, technical and nontechnical
challenges, and potential policy responses. According to this
report, cybersecurity is a never-ending battle; threats will evolve
as adversaries adopt new tools and techniques to compromise security.
Cybersecurity is therefore an ongoing process that needs to evolve
as new threats are identified. At
the Nexus of Cybersecurity and Public Policy is a call for action
to make cybersecurity a public safety priority. For a number of
years, the cybersecurity issue has received increasing public
attention; however, most policy focus has been on the short-term
costs of improving systems. In its explanation of the fundamentals
of cybersecurity and the discussion of potential policy responses,
this book will be a
resource for policy makers, cybersecurity and IT professionals,
and anyone who wants to understand threats to cyberspace.”
ISPs are Monopolies.
Monopolies do things companies with competitors don't dare to do.
What did you expect?
Level 3 Communications,
a company that provides bandwidth for a wide variety of customers
trying to get content from point A to point B on the internet, just
accused five U.S. ISPs and one European ISP of using their market
power to interfere with how traffic flows from Level 3 onto the ISPs’
last-mile network. The result is that customers of those ISPs
experience degraded quality for services going over Level 3′s
network.
This is a so-called
peering
problem. The topic has been in the news since early this year,
when consumers began complaining
about the quality of their Netflix, Hulu and Amazon Instant Video
streams on networks like Comcast, AT&T, Verizon and Time Warner
Cable. The issue is that at the interconnection points where Netflix
traffic attempts to enter the last-mile ISP’s network, there isn’t
enough capacity. Usually, when that happens, the transit provider or
the content provider negotiate to add more capacity by opening up
more ports. (I explain the
process in this story.)
However, in recent
months Level 3, Netflix and Cogent have all gone public accusing
some ISPs of keeping those ports congested while trying to charge
above-market rates for direct interconnection. Netflix has signed
such a direct interconnection agreement with both Comcast
and Verizon.
But it isn’t
happy about it and accuses the ISPs of abusing their market power
to extract payments from content companies trying to serve the last
mile.
Perhaps I could ask my
students...
Why
the $20 smartphone won't be the next burner cellphone
News reports are
bursting with the revelation of a $20 Android smartphone coming from
chipmaker ARM by this summer, and the development will open up the
Internet to millions of consumers who have only had access to text
messaging.
… According to one
report ARM has claimed $20 is rock bottom in terms of devising an
inexpensive smartphone offering. The report states ARM's smartphone
device will feature single-core Cortex-A5 processor and 2.5G wireless
data.
Another news outlet is
dismissing the device, describing it as almost a throwaway, a new
kind of 'burner' phone, noting most users don't want such low-level
functionality.

Track,
Compete, Socialize, Explore With Strava Running & Cycling For
Android
… Strava
is an Android app (included on our Best
Android Apps page) that records and tracks your running and
cycling habits. The idea of tracking how far and where you
go with GPS is a fairly recent development in the fitness world,
although it’s taking off fast.
In this article, we’re
going to focus on the functions and features of using the Strava
Android app. However, Strava is also one of the must-have
iPhone apps for cyclists. If you use a standalone GPS device
(see supported
GPS devices), Strava works perfect for many of those too.
Unfortunately, this
applies to many, many areas of business and academia...
