The Top 3 Challenges of AI-Powered Voice Technology

Aggregated on: 2022-11-11 16:43:43

The promise of artificial intelligence (AI) that can generate human-like data has been talked about for decades. Yet, data scientists have tackled this problem with little success. Pinpointing effective strategies for creating such systems has presented challenges that run the gamut from technical to ethical and everywhere in between. However, generative AI has emerged as a bright spot to watch. At its most basic, generative AI enables machines to use elements such as audio files, text, and images to produce content from speech, to writing, to artistry. According to tech investor Sequoia Capital, “Generative AI is well on the way to becoming not just faster and cheaper, but better in some cases than what humans create by hand,” according to a recent Tech Monitor interview.

VR in Healthcare: Market Trends, Use Cases, and Growth Potential

Aggregated on: 2022-11-11 14:43:43

Developed for several decades, virtual reality or VR technology attracted significant attention in 2012 with the launch of HMD (head-mounted play) products, such as Oculus Rift and Google Cardboard. Before then, virtual reality was mostly used in video games and entertainment. The new developments, however, quickly increased the number of possible VR uses. Combined, AR (augmented reality) and VR technologies were valued at $15.3 billion in 2020, with a projected growth of $77 billion by 2027. Out of all industries adopting virtual reality, healthcare has been among the leading ones. VR and AR in healthcare were valued at 1,206 billion in 2021, and there is a projected increase to $11,658 billion by 2028. So where does the healthcare segment of VR stand right now, what are its key uses, and is there room for new players in the already competitive market? Those are some of the things we will investigate in this article.

Typescript Interview Questions and Answers

Aggregated on: 2022-11-11 14:43:43

Top 20 Typescript Interview Questions and Answers 1. Define TypeScript Answer: A compiler may accept TypeScript as a superset of JavaScript and create ordinary JavaScript from it since it is clearly typed. Dealing with JavaScript in a totally object-oriented context is made possible by TypeScript. Use classes and interfaces in this situation. It is also labeled, much like C# or Java. You'll need a TypeScript compiler to turn the code into a JavaScript file, which you can then utilize.

3 Docker Desktop Extensions Every Developer Must Try

Aggregated on: 2022-11-11 00:58:42

The world of software development is changing faster than ever. The need for faster release cycle times has led to a proliferation of virtualization technologies. Virtual machines (VMs) have been around for many years, but containers have recently overshadowed them because VMs are slower and not as lightweight as containers. With the popularity of microservices, containers have emerged as an excellent alternative to virtual machines for developing, testing, and deploying applications in a lightweight environment. There comes Docker, an open-source technology that uses Linux containers to virtualize apps and other software processes so they can run independently and more securely in another container as if they were separate computer programs on the same device.

We achieve this by using the Jolie programming language, npm, VS Code, and Docker. Prerequisites You will need npm, Docker, and VS Code installed. Make sure that you have enabled support for Dev Containers in VS Code. (Jolie comes preloaded in the Docker images that we are going to use, so no need to install it.)

Basic Implementation of CI/CD in Android Development

Aggregated on: 2022-11-10 20:13:42

CI/CD is a software development practice most mobile developers in team projects use daily; however, most times, the Version Control practices (or git branching strategy) as well as the automated testing/deployment is already established and will only require small changes if anything. On the other hand, when working on individual or personal projects, setting up our own CI/CD pipelines can seem overkill if not with a learning motive or client requirement. As a result, many mobile developers might feel like CI/CD falls outside their fields of expertise, and perhaps without the use of a mobile DevOps platform, this might be the case, but mobile CI/CD automation has never been easier through the use of these platforms.

Technology for People: How to Develop an Engineering Culture and Make a Quantum Leap In Development

Aggregated on: 2022-11-10 16:58:42

Software Developer, Technical Recruiter, HRD, VP of Corporate Development, VP of Delivery, and Head of Manufacturing, Supply Chain, and Logistics are all pivotal destinations of my career journey. Such a trajectory may raise questions for a layman: development, HR, and management seem to lie in different dimensions. In fact, for me, as a leader in a technology company, this is pretty logical. I have always realized that all innovative solutions are created by people and for people. Given this, my goal was to obtain a non-trivial combination of technological base and knowledge about how and why people think and behave. I needed to master the skills of negotiations and sales and understand what exactly stands behind one’s goals, thinking, setting tasks, motivation, and what one’s pains and expectations are. This body of knowledge empowers me to offer technology that will be maximum beneficial. It also helps me with the team: to inspire, guide, help them grow, and become leaders.

5 API Abuse Use Cases and How to Prevent Them

Aggregated on: 2022-11-10 16:58:42

What Is a Vulnerability? Sometimes, vulnerabilities are straightforward flaws due to bad design. For example, the Tacoma Narrows Bridge in the state of Washington was built in 1940 and collapsed later that year in a 40-mph wind due to poor construction. No lives were lost (the suspension bridge underwent reconstruction in 1950 and is still standing). Sometimes, though, vulnerabilities are part of the actual design. Consider door locks. A door lock is not flawed because it can be unlocked. There’s no inherent design flaw in how the pins and tumblers are precision-crafted and laid out. The issue is not that the structure is poor, but their structure and precision design provide a consistent way for would-be thieves to know how to pick them. (For more information on locksport, one good organization is TOOOL).

Security Implications of URL Parsing Differentials

Aggregated on: 2022-11-10 15:58:42

During my team's security research on an authentication module for Apache2, my team and I identified an issue introduced by how the HTTP server Apache2 and modern web browsers parse URLs differently. Although the general problem of differential URL parsing has been documented publicly, I think it did not get the attention it deserved. It can impact a broad range of software and introduce vulnerabilities in critical features like authentication flows and requests to internal services. In this blog post, I detail how differential URL parsing bugs can occur and what URL parser libraries are affected. I'll use a recent bug that we discovered in mod_auth_openidc, a popular Apache2 module, to give you a real-life example of this pattern and then show you how to detect similar bugs in your application through differential testing easily. With this, I hope to raise awareness about these subtle bugs and add a new item to your toolbox!

Will Open-Source SDKs Improve the Adoption of Confidential Computing?

Aggregated on: 2022-11-09 17:43:42

If you have been following the Confidential Computing space, you would have noticed that many Software Development Kits (SDKs) that use Trusted Execution Environments (TEEs) are pursuing the open-source route. It might seem counter-intuitive that the SDKs promoting privacy-first computing allow their source code to be visible for everyone to see. However, open-sourcing an SDK is essential to improve the trust and transparency of a privacy-enhancing technology.

Saving Interesting Observability Data Using SLO-Based Retention Policy

Aggregated on: 2022-11-09 17:13:42

In any data management policy, there are two extremes: save everything (just in case), and delete everything that ages out. The two extremes work hand in hand, as eventually, you decide that even if you want to save it all, the realities of storage costs have forced you to delete your data arbitrarily. Ideally, you would retain "interesting” data that might be useful and delete the rest. Even better would be to not collect the data in the first place.

There are a ton more libraries than just these, but I can't speak to libraries I haven't used, and I think these are the ones getting used the most.

Are 45 Minutes Sufficient for a System Design Interview?

Aggregated on: 2022-11-09 16:13:42

I am working as a Senior Software Engineer(Backend) at Netflix. System Design interviews are part of every interview cycle, be it for a beginner role, intermediary, or senior role at every big or small company. I myself struggled with design interviews, felt I was all over the place, and could not come up with a single flow design in 45 mins. One question I always had was: "How can I solve it in 45 minutes when it took hundreds of engineers a few years to solve?" After reading several design interview articles and books and taking and giving several interviews, I came up with my strategy to handle this. Most of us are familiar with the technical aspect of design but lack the ability to structure or frame a complete (not right or wrong) solution in 45 mins. I will focus on how to structure the problem in time, in the most effective and efficient manner. My main focus will be on backend design.

Developers do not often pay attention to licenses when using various open-source projects. We can often use projects/part of a project or functions for our applications and programs without thinking about how it might affect the future. Do you need to keep the copyright? What are the requirements and obligations of different licenses? In this article, I want to highlight the issue of choosing licenses for the project and the specifics of using projects with different types of licenses. Here and below, the project refers to an open-source project or repository.

In this blog, you can find my takeaways of Devoxx Belgium 2022! 1. Introduction Devoxx Belgium is the largest Java conference in Europe. This year, it was already the 19th edition. As always, Devoxx is being held in the fantastic theatres of Kinepolis Antwerp. The past two editions were cancelled due to COVID-19. As a result, there was a rush on the tickets. The first batch of tickets was sold out in 5 minutes, the second batch in a few seconds. Reactions on Twitter mentioned that it looked like a ticket sale for Beyonce.

Create Realistic Lighting With DDGI

Aggregated on: 2022-11-09 03:13:41

Why We Need DDGI Of all the things that make a 3D game immersive, global illumination effects (including reflections, refractions, and shadows) are undoubtedly the jewel in the crown. Simply put, bad lighting can ruin an otherwise great game experience. A technique for creating real-life lighting is known as dynamic diffuse global illumination (DDGI for short). This technique delivers real-time rendering for games, decorating game scenes with delicate and appealing visuals. In other words, DDGI brings out every color in a scene by dynamically changing the lighting, realizing the distinct relationship between objects and scene temperature, as well as enriching levels of representation for information in a scene.

Superheroes Cannot Scale to Meet Application SLAs, But They Can Enhance Their Superpowers

Aggregated on: 2022-11-09 03:13:41

Everywhere one turns, at least in the movie theater or small screen, there is a new superhero with some new power or focus. Given how important application or site uptime is, it’s a wonder that there isn’t yet a superhero for troubleshooting software problems. In a way, though, superheroes have existed for some time and have been the primary means of keeping applications running smoothly. These Software Reliability Engineers (SREs) or support superheroes are highly skilled at finding a solution — if not the actual root cause — of issues based on their deep experience, knowledge, and intuition. But these software superheroes cannot scale to meet the new reality caused by the combination of ever-increasing complexity and the accelerating rate of application change. The combination is driving a steady growth in incident numbers, and observability tools are not the problem. The limitation is the amount of information the human mind needs to quickly absorb and analyze to resolve these incidents.

Why Yoda Never Used Microservices

Aggregated on: 2022-11-08 23:43:41

Microservices were meant to be a blessing, but for many, they’re a burden. Some developers have even moved away from them after negative experiences. Operational complexity becomes a headache for this distributed, granular software model in production. Is it possible to solve microservices' problems while retaining their advantages? Microservices shorten development cycles. Changing a monolithic code base is a complex affair that risks unexpected ramifications. It’s like unraveling a sweater so that you could change its design. Breaking that monolith down into lots of smaller services managed by two-pizza teams can make software easier to develop, update, and fix. It’s what helped Amazon grow from a small ecommerce outfit to the beast it is today.

Is Python Effective for Microservices Architecture?

Aggregated on: 2022-11-08 23:43:41

Python is one of the options when choosing between programming languages suitable for microservices architecture. It has perks like an active community, better prototyping, and popularity among developers. It has some limitations, so other languages can be used to avoid them. Quick Development Architectural Style Review and Statistics Two main development architectural styles are monolithic architecture and microservices architecture. Monolithic has an all-in-one principle and functions as an integral structure, which works best for small development projects or start-ups. When a platform grows and a business needs complex applications, it'll be reasonable to split it into a microservices architecture.

17 DevOps Metrics You Should Be Tracking

Aggregated on: 2022-11-08 20:43:41

Productivity in software development has always been tricky to measure. Unlike in other industries, the act of programming is not something that’s easy to parallelize. The development process is unique in that it requires a diverse mix of technical and communications skills, which calls for a set of specialized metrics to keep track of the team’s vitals. The Pulse of Software Development Not all metrics were created equal. Depending on the context, some are more useful than others. The things we choose to measure can help us find problems or obscure them behind irrelevant data and non-productive goals.

List in C#: Implementation and Features

Aggregated on: 2022-11-08 20:13:41

List is one of the most used collections in C#. Let's inspect the features of List and look at how some of its parts are implemented. This article is about List<T> from the System.Collections.Generic namespace. More specifically, the article describes the internal implementation and some features of List<T>. This is the most used collection in C#, and it's not just my opinion — Andrew Troelsen, Philip Japikse, and Jon Skeet wrote the same in their books. And that's understandable: List<T> is easy to work with. It's quite flexible and thus covers most of the daily tasks for developers. It also has a large number of helpful methods. The collection's abilities are expanded even further with the help of LINQ.

Use of AWS Step Function to Modernize Asynchronous Integration With Oracle ERP Cloud – A Case Study

Aggregated on: 2022-11-08 20:13:41

AWS offers a handful of services for integration. Though AWS is not that way a full-fledged Integration Tool like the well-known ones in the market as Oracle Integration Cloud, Oracle Service Bus or MuleSoft, and many more, there can be potentially effective solutions implemented leveraging the existing service offerings in AWS. This case study is about the modernization of an existing integration in Oracle Integration Cloud by re-solutioning the same in AWS. Background It can be an interesting question that why suddenly a Retail business would wish to migrate a live integration to AWS given the current one is already on the cloud (supposedly already taking advantage of the “pay as you use” flavor of Oracle Cloud). The potential reason is the business at the enterprise level, investing more on AWS, was eventually more inclined to have everything on the same cloud than subscribing to another just for the sake of integrations. Another reason was the lack of resources having the proper skills and expertise to support and debug the integration. Nevertheless, there has been a major shift of technical inclination of the businesses towards having things integrated using microservices on a Cloud rather than paying for a dedicated integration product. This case study is also not an exception.

This article will demonstrate the heterogeneous systems integration and building of the BI system and mainly talk about the DELTA load issues and how to overcome them. How can we compare the source table and target table when we cannot find a proper way to identify the changes in the source table using the SSIS ETL Tool? Systems Used SAP S/4HANA is an Enterprise Resource Planning (ERP) software package meant to cover all day-to-day processes of an enterprise, e.g., order-to-cash, procure-to-pay, finance & controlling request-to-service, and core capabilities. SAP HANA is a column-oriented, in-memory relational database that combines OLAP and OLTP operations into a single system. SAP Landscape Transformation (SLT) Replication is a trigger-based data replication method in the HANA system. It is a perfect solution for replicating real-time data or schedule-based replication from SAP and non-SAP sources. Azure SQL Database is a fully managed platform as a service (PaaS) database engine that handles most of the management functions offered by the database, including backups, patching, upgrading, and monitoring, with minimal user involvement.
