Thanks to the information revolution, a stunning 90% of the data created by humanity has been generated in just the past two years. Yet the math taught in U.S. schools hasn’t materially changed since Sputnik was sent into orbit in the late 1950s. Our high school students are taught algebra, geometry, a second year of algebra, and calculus (for the most advanced students) because Eisenhower-era policymakers believed this curriculum would produce the best rocket scientists to work on projects during the Cold War. It has been 50 years since the U.S. reached the moon, almost 30 years since the Berlin Wall fell. Technology has advanced to the point that tiny powerful computers are routinely carried around in pockets and purses. Times have changed, and so has the math people use in everyday life. We surveyed 900 “Freakonomics” podcast listeners — a pretty nerdy group, we must admit — and discovered that less than 12% used any algebra, trigonometry or calculus in their daily lives. Only 2% use integrals or derivatives, the foundational building blocks of calculus. In contrast, a whopping 66% work with basic analytical software like Microsoft Excel on a daily basis. When was the last time you divided a polynomial? If you were asked to do so today, would you remember how? For the most part, students are no longer taught to write cursive, how to use a slide rule, or any number of things that were once useful in everyday life. Let’s put working out polynomial division using pencil and paper on the same ash heap as sock darning and shorthand. What we propose is as...

At a time when global cyber threats seem to be emerging everywhere, the U.S. White House appears to be ignoring the potential risk of a cyber attack carried on the White House’s computer networks. What is most alarming is a recent exodus of at least a dozen senior cyber security officials, all of them former members of the Office of the Chief Information Security Officer (OCISO). In July 2019, the White House carried out a reorganization, in which these members of the White House cyber security team were shifted into the Office of the Chief Information Officer (OCIO). In the aftermath of this shakeup, former OCISO officials have had their scope of duties removed, and many of their security privileges revoked. All of this is setting up a situation where members of the U.S. Congress are starting to wonder about the long-term security posture of the White House. The politicization of cyber security There’s a lot to unpack here, primarily due to the rampant partisan politics in Washington, D.C. On one hand, the Trump Administration has characterized the reorganization of the OCISO cyber security team as simply a way to improve the overall efficiency and productivity of the White House’s cyber activities and a better way to protect White House computers. Why have two different cyber security teams – the OCISO and the OCIO – carrying out nearly the same duties? There’s a lot of redundancy and inefficiency here, right? On the other hand, opponents of the Trump Administration suggest that the forced exodus of cyber staffers to the private sector is part of a bigger conspiracy, in which...
In the last decade, computer engineering has exploded with solutions based on cloud computing, distributed systems, big data, streaming or artificial intelligence. Today’s world systems are data-intensive so that volumes become higher and cheaper. Shortly speaking, data is at the centre of our interests. One of issues in these area is a data quality — why is it so important? Nowadays, data is everywhere and drives companies and their operations. If we do not make decisions based on reliable or complete information, it might have a huge impact on these and end up with tragic consequences. The data’s correctness and prominence reserves a special discipline, known as a data cleansing, which is focused on removing or correcting coarse records. cleanframes is a small library for Apache Spark to make data cleansing automated and enjoyable. Let’s walk through a problem, step by step, to examine what it takes to make data quality as awesome and reliable as possible! Let’s introduce a sample data and, for a simplicity-sake, make it a small set: And a domain model that, for its representation, is defined as: If you are wondering why there are options across the case class the answer is simple: Scala primitives are values and cannot be nulls. Options liberate us by setting the dataframe schema columns’ nullability to true. Let’s load the data and check what Spark will do about it: The collect variable contains the following result: As you can see, due to malformed values, the second and fourth lines don’t retain the correct data and reject entire rows. We would be much better off if it would be possible to ignore only invalid cells and...
Cyber attacks are happening in today’s world. It can also lead to data breaches where confidential information is leaked online and then exploited by criminals to commit financial fraud. In a bid to put an end to all these illegal activities, 25-year-old Shubham Singh is helping the police department solve complex cases. At a young age itself, Shubham Singh has impressed Mumbai police force with his hard work and dedication. He had the opportunity to lecture the Mumbai Police on ethical hacking and assisting them to solve tough cybercrimes. He was brought up in a family where computer technology was not common. The turning point of his life was when his Facebook profile was hacked. He started to learn a lot of YouTube videos and other important sources of information for rectifying the problem and he finally got his account back. This very learning experience got him motivated and his passion and interest in ethical hacking increased even more. There is a specific reason as to why they made up their mind to work with the Mumbai Police. The journey began last year when he was lecturing at an institute in Vikhroli. Impressed by his teachings and his interest to tackle cybercrimes, one of his professors put him in touch with the police department. He then started helping them by solving a case with his technical knowledge. Since then, he has been connected with Mumbai Police and has played an important role in solving several cases. Shubham Singh now runs his own start-up named “Cyber World Academy in Vikhroli” which is in collaboration with his friend Soumya Mondal. They...
We are very excited to announce our 2019 fourth and final release, Kali Linux 2019.4, which can be downloaded immediately. This brings the kernel up to version 5.2.9 and includes a variety of new features across the board including NetHunter, ARM and packages (plus fixes and updates for normal bugs). Features Included In Kali Linux 2019.4 So now let us have a detailed look on the same; New Desktop Environment and GTK3 Theme A long time has come for an upgrade to the desktop environment. Since months now, we’ve been thinking about how to fix it, what we needed to do, experimenting with different methods, and so on. We had a few issues that we wanted to address head-on as a summary like Performance issues, Fractured user experience and Modern look. In order to sort this issue, they have tracked down Daniel Ruiz de Alegría and started the development of a new theme running on Xfce. They considered Xfce, since addressed them best while still being accessible to the majority of users. We’re very excited about this new UI update, and it’s going to love all kali users. But as the UI can be a little like religion, don’t worry if you don’t want to abandon Gnome. They still have a Gnome build for you, with a couple of changes in place. As time goes on, they’re going to make changes to all the desktop environments they release to get them “close” to a similar user experience regardless of what DE you run. Because we don’t have the resources to invest extensively in modifying all these different environments, this...
