AI in Cybersecurity: An Overview

Aggregated on: 2022-07-08 14:51:26

What Is Cybersecurity? Network safety or Cybersecurity is the act of safeguarding basic frameworks and touchy data from advanced assaults. Otherwise called data information technology (IT) security, these measures are intended to cope with the dangers that arranged frameworks and applications might face, irrespective of whether those dangers are external or internal. Security framework intricacy, made by divergent advancements and an absence of in-house ability, can intensify these expenses. Yet, associations with a complete network protection procedure, represented by best practices and robotized utilizing progressed investigation, man-made consciousness (AI), and data and machine learning can battle cyber threats all the more successfully and diminish the lifecycle and effect of breaks when they happen. In recent times, cybersecurity and Artificial Intelligence have become the flip sides of one same coin, cybersecurity cannot be dreamt of anymore without AI.

The native ecosystem integration enables projects to be automated from the moment developers commit code for deployment into production.

The Rise of RAD and Its Application in the Tech Industry

Aggregated on: 2022-07-08 03:36:26

Software development wasn’t always so fluid and efficient. The early beginnings of software development took months to prepare for and even more months in the development process, much like traditional engineering. Developers would come up with a plan that took laborious months and software architects would work directly with end users in order to come up with functional designs before defining them in spec sheets. If their clients didn’t like what the option they were presented with, it was back to the drawing board and developers would have to yet again start from scratch, taking even years to produce something that their clients first requested. Aside from opportunity cost, the expenditure to fund such undertakings were astronomical. In a bid to make software development much more cost-effective and time-efficient, RAD, or rapid application development, was proposed in the 1980s. The idea was that software development should be treated as a malleable and intuitive process, rather than something rigid as constructing a building. Instead of focusing on costly planning, RAD emphasized rapid prototyping.

How to Store Text in PostgreSQL: Tips, Tricks, and Traps

Aggregated on: 2022-07-08 00:51:26

DDL generation based on JPA entities definition is a daily task for many developers. In most cases, we use tools like Hibernate's built-in generator or JPA Buddy plugin. They make the job easier, but there are exceptions. When it comes to storing big chunks of data in the database, things get a bit complicated. Use Case: Storing Documents Let’s assume we need to store a document object with its content in the PostgreSQL database. The JPA entity code for this might look like the code below:

Two Principles of Geometric Deep Learning

Aggregated on: 2022-07-07 15:21:26

After CNNs exploded in 2012, showing unprecedented levels of prediction accuracy on image classification tasks, a group of researchers from Yann LeCun's team decided to extend their success to other, more exotic domains. Specifically, they started working on generalizing convnets to graphs. Their efforts were described in this influential paper. Since then, Graph Neural Networks have become a hot area of research within the ML community and beyond. Numerous papers have been published explaining how different kinds and flavors of GNNs can be applied to complicated, irregular, high-dimensional, non-grid-like structures (graphs, manifolds, meshes, etc.).

Data Quality Metrics to Know and Measure

Aggregated on: 2022-07-07 14:51:26

The most important characteristic for any organization is not data; it is quality data. In a study, IBM estimated that bad data costs the U.S. economy $3.1 trillion per year. Such costs are incurred when your employees spend time cleaning data or rectifying the errors caused by bad data. Apart from financial costs, bad data becomes a source of dissatisfaction and discontent between you and your customers, partners, and other business relationships. This clearly explains the importance of housing quality data in your organization. But what exactly is it, and how can you measure data quality? Let’s take a look.

Digital transformation is making every business faster, smarter, and more connected. At the same time, it’s also putting pressure on businesses to reduce their environmental footprint and make sure that their IT operations are socially responsible. Are we at a point where we were with security five years ago, where you can no longer ignore the importance of social governance in your IT environment? Data Security & Compliance When I began conducting interviews with IT executives for DZone in 2015, GDPR and data security were only the concern of CIOs and CTOs -- there weren't many CISOs then. Data security was a nuisance to CEOs, CSOs, and COOs. IT just needed to "handle it."

Authorization has become quite a hot topic: Intuit, Airbnb, Google, and others have recently described the architectural challenges surrounding authorization at scale and the solutions that they’ve built internally to address them. As a developer of a B2B SaaS application, you may be scratching your head about how this is relevant to you. Early on in your application’s lifecycle, these challenges may not be obvious: your application typically starts with “regular users” and “admins”; for admin-level operations, you write some code to check whether the logged-in user has admin rights. Life is simple.

How to Handle JavaScript Alert in Selenium WebDriver Using Python?

Aggregated on: 2022-07-05 21:06:25

Alert windows are widely used across websites where an alert message acts as a mode to ‘interrupt’ the current flow of the user journey. A simple example of a JavaScript alert would be someone filling in details on the sign-up page and submitting the details without entering some mandatory information. This user flow also needs to be verified when Selenium automation testing is performed on the web product. Handling pop-ups and alerts are one of the common test scenarios that should be tested using Selenium WebDriver. In this post of the Selenium Python tutorial series, we look at how to handle JavaScript alerts in Python. It is worth mentioning that the core fundamentals of JavaScript alerts and popups remain unchanged irrespective of the programming language used for Selenium.

How Intrinsic Type Manipulations Work in TypeScript

Aggregated on: 2022-07-05 19:36:25

Did you know that TypeScript comes with a bunch of built-in string manipulator types? That means we can easily transform a string type into uppercase, lowercase, or capitalized versions of itself. When might this be useful? In lots of situations where you have a fixed set of string values, for example, whenever you have a set of strings from an object using something like keyof. To transform a string into a different version by defining a new type along with one of the type manipulators. For example, below, we transform myType into the capitalized version:

Why More Incidents Are Better

Aggregated on: 2022-07-05 19:36:25

As most SREs how many incidents they’d have to respond to in a perfect world, and their answer would probably be “zero.” After all, making software and infrastructure so reliable that incidents never occur is the dream that SREs are theoretically chasing. Reducing actual incidents as much as possible is a noble goal. However, it’s important to recognize that incidents aren’t an SRE’s number one enemy. What matters more than the number of incidents you experience is how effectively you respond to each one.

Document Annotation, Its Industry Significance, and Best Practices

Aggregated on: 2022-07-05 19:06:25

By images and document annotation, we mean the process of identifying fields and values within a document in order to extract useful information. By using AI and machine learning algorithms, data sets in files can be categorized and extracted automatically without the need for manual intervention. When you mark up documents, you can easily find the information you are searching for without having to comb through the entire document. Data can be structured and shown in a clear and comprehensible format that other users can understand and appreciate as well. Image annotation traditionally is handled by specialized staff, with innovations in technology, OCR, and RPA eliminating the need for employees to look up information in documents manually and freeing up workers for more productive tasks.

Benchmarking PostgreSQL Workloads on Kubernetes

Aggregated on: 2022-07-05 17:36:24

Kubernetes used to be a platform that could only host stateless workloads, and while this has mostly changed with up to 90% believing Kubernetes is ready for stateful workloads, "databases like PostgreSQL cannot run on Kubernetes" is something that you can still hear. However, Gabriele Bartolini, Vice President of Cloud Native for EDB, and Francesco Canovai, System Engineer for 2ndQuadrant, think otherwise. But they don’t want us to take their words for granted. If a company is considering running Postgres on Kubernetes, the first question they should ask is “why”. Once the goal is figured out, benchmarking the setup is a great way to ensure that it will be performed as needed.

How to Use Automatic Mixed Precision Training in Deep Learning

Aggregated on: 2022-07-05 16:51:24

Why Use Mixed Precision Deep Learning? As advancements have been made in the field of deep learning, the discussion about mixed-precision training of deep learning models has seen a similar increase. These improvements and natural evolution of the scope, sequence, and raw power of neural networks mean that the size of these models has had to increase to compensate accordingly. Larger and more complicated deep learning models require advancements in technology and approach. This has led to multi-GPU setups with distributed training which can get out of hand quickly as more GPUs are integrated into training. Getting back to the basic training principles of deep learning and brushing up on fundamental techniques can ease the stress of the training phase of neural networks and optimize GPU usage. Mixed precision training or automatic mixed precision training can be a simple way to do exactly this.

Getting Your Developers to See Value With a Great Developer Experience

Aggregated on: 2022-07-05 16:21:24

One of the beauties of working with APIs is their convenient and practical ways to share data and applications. APIs have enabled a transformational shift from an interface that relied on custom integrations to now a relatively streamlined process. That said, because of their agile framework, some companies have overlooked the importance of providing a great developer integration experience and are not taking the necessary steps to help drive the Time To First Hello World. Unfortunately, it’s an all too common sentiment surrounding API management that the integration should be left to a hyper-intelligent developer to figure out and that standard onboarding workflows are unnecessary luxuries. However, this is a misguided notion; developers don’t want to be treated as second-class citizens; they want to be shown how to integrate and would appreciate the convenience of streamlined workflows.

Refactor Switch to a One-Liner

Aggregated on: 2022-07-02 16:51:22

Intro In this article, we’ll take a look at why switch is almost never a good idea in OOP. We are going to look from different perspectives at how it affects the code, tests, and maintainability. Afterwards, we’ll do some refactoring on our existing code and analyse the benefits of the newly refactored code. We’ll see how almost any (no matter how long) switch can and should be converted to an elegant one-liner. All the source code used in this article can be found here, which has two branches — the un-refactored code (main) and the result after refactoring (feature/refactor-switch). switch Is Almost Never a Good Idea How many times have you come across some code that you need to add some changes to or modify something, and you do this?
