Wireless attacks on aircraft instrument landing systems

The Morning Paper

Wireless attacks on aircraft instrument landing systems Sathaye et al., no longer hold: Security was never considered by design as historically the ability to transmit and receive wireless signals required considerable resources and knowledge. In fact, today the majority of wireless systems employed in modern aviation have been shown to be vulnerable to some form of cyber-physical attacks. USENIX Security Symposium 2019.

Protocol Testing?


Protocol Testing is a method of checking communication protocols in the domains of Switching, Wireless, VoIP, Routing, etc. What Is Protocol Testing? The primary goal of protocol testing is to check the structure of packets that are sent over a network using protocol testing tools.

Stuff The Internet Says On Scalability For February 8th, 2019

High Scalability

EFF : EU countries that do not have zero rating practices enjoyed a double digit drop in the price of wireless data after a year. In comparison, the countries with prevalent zero rating practices from their wireless carriers consistently saw data prices increase. Wake up! It's HighScalability time: Change is always changing.

The Future in Visual Computing: Research Challenges

ACM Sigarch

For many IoT applications involving wireless video sensors (e.g. As the amount of video being streamed keeps increasing at a rapid pace, it is important to make efficient use of wireless bandwidth, while not adversely impacting the accuracy of computer vision analysis. The tremendous growth in visual computing is fueled by the rapid increase in deployment of visual sensing (e.g. cameras) in many usages ranging from digital security/surveillance and automated retail (e.g.

Fallacy #5: Topology doesn't change

Particular Software

Some protocols can run afoul of this changing topology — even something simple, like a wireless client disconnect. If one of these clients is on a wireless connection that gets interrupted, the client proxy continues to exist.

The Paradox of Connection

Edge Perspectives

Wireless technology has made it possible for us to connect to this digital infrastructure (and to each other) regardless of where we are in the world with much less expense and effort. We are becoming more connected with each other and less connected with each other at the same time. The Big Shift that we're experiencing on a global scale is full of paradox – this is just one of many, but a particularly important paradox to acknowledge and address.

Have You Tested Your App Performance & Capacity Recently?


Global consumers have high expectations for seamless access via wireless and mobile networks, regardless of their location and the complex, technological components underneath. 2019 will go down as the year when giants collided over who is streaming the right content to win the growing market demand and dollars. Disney announced they would have a streaming service, while Netflix subscribers reached an all-time high with 137.1 million Netflix users as of Q3 2018.

HTTP/3: Performance Improvements (Part 2)

In those set-ups, however (if they’re done correctly), your device will typically keep its IP intact, because the transition between wireless base stations is done at a lower protocol layer. Other causes of packet loss can lead to fewer or individual packets becoming lost (or unusable), especially on wireless networks. HTTP/3: Performance Improvements (Part 2).

A More Ergonomic Setup

Tim Kadlec

I tested my typing on my wireless keyboard before plugging in the ErgoDox so I could compare. My neck and shoulders have bothered me since high school. Nothing debilitating, but a constant soreness and dull ache. I’m not 100% sure why but certainly my work environment is a very likely candidate. My posture can be questionable and for the longest time, I didn’t give even the slightest thought to the ergonomics of my setup.

Sprint's Marathon

The Agile Manager

While a post-merger AT&T/T-Mobile and Verizon Wireless would have most of the customers, there are no switching penalties for long-term handset contract customers. There's been a lot of public hand-wringing at the proposed AT&T / T-Mobile USA merger, particularly with regard to Sprint. Sprint is a distant third in subscribers today, but this is a very dynamic market. Today's subscriber count may not be relevant to tomorrow's.
