WASHINGTON — Twenty-seven states activated National Guard cyber security cells in November 2018 to help ensure critical network infrastructure remained unobstructed during the mid-term elections, the Guard’s top general said Tuesday, predicting more states would deploy such teams in 2020. As concerns about elections security in the United States have risen in recent years amid threats from Russia and others, the National Guard has increased the size of its cyber force and turned to experts within its ranks who have honed critical cyber skills in their civilian jobs, Air Force Gen. Joseph Lengyel, the commander of the National Guard Bureau, told reporters at the Pentagon. Though those National Guard units were not forced to contend with an active threat to elections in 2018, governors and others have recognized the need to have their own state-level forces prepared to ensure no one tampers with U.S. elections, just as Guard members provide them the ability to respond to a natural disaster, the general said. “Our goal as men and women of the National Guard is to be able to offer these kinds of service to our governors to respond to a domestic event, whether it’s a hurricane, a fire, a flood or a cyber event. It’s just another military skillset that we have that can be used,” Lengyel said. “… Election network security is a very state-centric thing. We’re an additive measure that can augment state response entities … and we’re trying to grow it.” Today, the National Guard boasts some 3,900 cyber troops in 59 cyber units with elements in all 50 states. But it has also looked to cyber...
An Artificial Neural Network (ANN) is a computational model that is inspired by the way biological neural networks in the human brain process information. Artificial Neural Networks have generated a lot of excitement in Machine Learning research and industry, thanks to many breakthrough results in speech recognition, computer vision and text processing. In this blog post we will try to develop an understanding of a particular type of Artificial Neural Network called the Multi Layer Perceptron. A Single Neuron The basic unit of computation in a neural network is the neuron, often called a node or unit. It receives input from some other nodes, or from an external source and computes an output. Each input has an associated weight (w), which is assigned on the basis of its relative importance to other inputs. The node applies a function f (defined below) to the weighted sum of its inputs as shown in Figure 1 below: Figure 1: a single neuron The above network takes numerical inputs X1 and X2 and has weights w1 and w2 associated with those inputs. Additionally, there is another input 1 with weight b (called the Bias) associated with it. We will learn more details about role of the bias later. The output Y from the neuron is computed as shown in the Figure 1. The function f is non-linear and is called the Activation Function. The purpose of the activation function is to introduce non-linearity into the output of a neuron. This is important because most real world data is non linear and we want neurons to learn thesenon linear representations. Every activation function (or non-linearity) takes a single number and performs a certain fixed mathematical operation on it . There are several activation functions you may encounter in practice:...
First, let me introduce myself. My name is Sergei Garcia, and I’m a full-time front end developer with 2 years experience. In that time, I’ve worked as a front-end developer for both a Forbes 500 consulting firm and a small company.This may not sound like a lot of experience, but finishing my second year as a developer has been a huge milestone for me. This is because I had no real experience doing web development — and not much programming experience in general beyond some basic C# and Java training I got from a few online courses. I also didn’t have a computer science degree since I graduated with a degree in IT project management.I’d never written about my experience despite all the help I’ve received from wonderful resources like Medium, Stack Overflow, and Reddit’s programming subreddits. So today, I decided to change that. Today I’m going to fill you in on what went right, and what didn’t, so that if you’re embarking on this journey, you’ll have better luck than I did.I know that there are a lot of articles like this, but not very many of them discuss the process with the benefit of an extra two years of hindsight.I’ll start off with my journey, including what went wrong along the way. If you just care about what my suggestions for the shortest possible route to becoming a web developer from scratch are, feel free to skip to the last section: The shortest route .So, without any further ado, Let’s get started! Getting the Basics After deciding I wanted to get into web development the first question...

Stratford Mayor Dan Mathieson says it’s time Ontario municipalities start taking cyber security seriously. In a first for the university and possibly a first in the province, Ryerson University’s Rogers Cybersecure Catalyst has partnered with the City of Stratford and investStratford to bring together cyber security experts and representatives from more than 50 Ontario municipalities — most from the southwest region — in Toronto on Nov. 13 to begin a discussion around cyber security and tackle the threat of cyber attack head on. “After Stratford was hit with a cyber attack in April, Catalyst, which is a Ryerson program around cyber security, reached out to me to have a conversation,” Mathieson said. “They are trying to build a best-practices model.” After speaking with staff at the Cybersecure Catalyst on several occasions, an opportunity to host a broader conversation with municipal leadership across the province presented itself. “It’s an opportunity to just get local government, cyber security experts, and the province all in the same room and start having conversations around best practices, opportunities for partnerships, and really take what was a negative situation for the City of Stratford and try to turn it into a positive for us and help us in the future, and also help our other municipal partners and the government,” Mathieson said. According to the event’s agenda, discussions will focus around identifying the cyber security risks Ontario municipal governments are facing, defending local governments against those risks, and responding to cyber attacks when they happen. Mathieson will kick off the event by sharing the lessons learned through Stratford’s experience, which will be followed by presentations...
